US Military Aids Recovery in Typhoon-Ravaged Philippines

The U.S. military is assisting with recovery efforts and humanitarian relief in the Philippines in the aftermath of Typhoon Haiyan, which caused devastating damage and is estimated to have killed more than 10,000 people. Over the weekend, Defense Secretary Chuck Hagel directed the U.S. Pacific Command to help local search-and-rescue operations in the central Philippines, and provide air support to monitor the effects of Super Typhoon Haiyan, which battered the island nation when it made landfall last Thursday (Nov. 7). The deadly typhoon (known as Typhoon Yolanda in the Philippines), which reached super typhoon strength, has become one of the largest Pacific storms ever recorded. It ravaged the coastal city of Tacloban with storm surge that reached up to 20 feet (6 meters) in places, whipped up by winds that were estimated at 195 mph (314 km/h) hours before landfall.

Lice Reveal Clues to Human Evolution

GAINESVILLE, Fla. — Clues to human evolution generally come from fossils left by ancestors and the molecular trail encoded in the human genome as it is tweaked over generations. in spite of human attempts to get rid of the parasites, their persistence has made them a potential reservoir of information for those who want to know more about human evolution and history, said David Reed, associate curator of mammals at the Florida Museum of Natural History, on Sunday (Nov. 3) here at the ScienceWriters2013 conference. Clues from the bloodsucking hitchhikers, for instance, suggest modern humans intermingled with Neanderthals (a theory also supported by other genetic research) and that humans may have first put on clothing before leaving Africa.

A ride fit for a president, Car Force One is a luxury car service that chauffeurs you around the New York area in the most teched-out car in the world. According to Car Force One founder and CEO Ishai, the company's priority is customer satisfaction. It's for the clients," said Ishai, who declined to divulge his last name.

Bacteria Control Hyena Communication

But the hyenas themselves do not produce these scents — they are actually the product of bacteria that live in the animals' scent glands, a new study shows. As bacterial communities within scent glands change and evolve, so do the odiferous compounds that waft forth, said Kevin Theis, lead author of the study and an ecologist at Michigan State University. "It's an extremely important study showing the role of bacteria mediating interactions between mammals," said David Hughes, a researcher at Penn State who wasn't involved in the study. They then took the material back to Michigan State, where they identified the types of bacteria by looking at their genes, and analyzed the chemical odors with a technique called mass spectrometry.

Incoming Comet ISON Now Visible in Binoculars

The potentially dazzling Comet ISON has brightened enough on its highly anticipated approach toward the sun that it's now visible through a decent pair of binoculars. Skywatchers around the world have recently used binoculars to spot Comet ISON, which is streaking toward a close encounter with the sun on Nov. 28 that will bring the icy wanderer within just 730,000 miles (1.2 million kilometers) of the solar surface. "I have made my first confirmed binocular sighting of C/2012 S1 ISON as well," Pete Lawrence, of the town of Selsey in the United Kingdown, told the website Spaceweather.com on Saturday (Nov. 9). "ISON's head appears small and stellar through a pair of 15x70s optics." [See amazing photos of Comet ISON by stargazers]

Effect of Most Vitamins on Cancer Is Inconclusive

Taking vitamin E or beta-carotene does not appear to reduce the risk of cancer or cardiovascular disease, according to a new review from a government-appointed panel of experts. However, there isn't enough evidence to say whether other vitamins or minerals (such as vitamin D, calcium and selenium) or multivitamins reduce the risk of these two conditions, according to the review from the U.S. Preventive Services Task Force. Although the effect of vitamins is unclear, some studies do suggest that a healthy diet reduces the risk of cancer and heart disease, the researchers said. "In the absence of clear evidence about the impact of most vitamins and multivitamins on cardiovascular disease and cancer, health care professionals should counsel their patients to eat a healthy, well-balanced diet that is rich in nutrients," said Dr. Michael LeFevre, co-chair of the task force.

Astronaut Sees Super Typhoon Haiyan from Space (Photo)

An astronaut in orbit has snapped a striking view of Super Typhoon Haiyan as it appears from space — an image taken one day after the monster storm devastated the Philippines as it heads toward Vietnam. NASA astronaut Karen Nyberg spotted Typhoon Haiyan through a window on the International Space Station on Saturday (Nov. 9), just one day after the storm caused widespread damage and loss of life in the Philippines. The so-called super typhoon slammed into the Philippines on Friday (Nov. 8) and has been blamed for potentially thousands of deaths due to storm flooding and widespread devastation, according to the Associated Press. According to the Associated Press, the Typhoon Haiyan had sustained winds of up to 147 mph (235 km/h) and gusts of up to 170 mph (275 km/h).

Dig for Hominid Bones Begins in Cradle of Humankind

An expedition to probe the deep recesses of a cave that may contain fossilized specimens of early humans is currently underway in South Africa. An international team of paleoanthropologists is exploring the Rising Star Cave at a site in South Africa dubbed the Cradle of Humankind, which is located roughly 25 miles (40 kilometers) north of Johannesburg. The Cradle of Humankind is one of the richest fossil sites in Africa, and was inscribed as a UNESCO World Heritage Site in 1999. The scientists found several hominid fossils, including a mandible, which forms part of the lower jaw.

Execs Watching Porn a Leading Cause of Computer Viruses

While employees may get the brunt of the blame for security breaches, company leaders are doing their fair share of damage as well, a new study finds. Research from ThreatTrack Security revealed that 40 percent of security professionals found that a device used by a member of their company's senior leadership team had been infected by malware because of a visit to a pornographic website, and nearly 60 percent of the security professionals surveyed have cleaned malware from a device after an executive clicked on a malicious link or was duped by a phishing email. In addition, 45 percent of respondents said they have found malware on a senior leader's device because the executive allowed a family member to use it, with one-third of security professionals discovering it on an executive's mobile devices because they installed a malicious app. ThreatTrack CEO Julian Waits Sr. said that while it is discouraging that so many malware analysts are aware of data breaches that enterprises have not disclosed, it is no surprise that the breaches are occurring.

GlaxoSmithKline heart drug misses goal in major study

drug, designed to fight heart disease in a new way, failed to meet its main goal in a major late-stage clinical study, dealing a blow to one of the company's biggest new treatment hopes. Darapladib's inability to reduce the overall risk of heart attacks and strokes in the first of two big Phase III studies is disappointing, but not a huge surprise. Shares in Britain's biggest drugmaker had fallen 1.2 percent on the news by 1050 GMT on Tuesday, and Deutsche Bank analyst Mark Clark said failure of the drug removed some "blue sky fantasy" about potential multibillion-dollar sales. GSK obtained full rights to darapladib, along with lupus drug Benlysta, when it bought U.S. biotech firm Human Genome Sciences last year for $3 billion.

The Physics of Peeing, and How to Avoid Splash-Back

Enter the Splash Lab at Brigham Young University, where researchers are trying to figure out how to prevent urinal splash-back. Fluid dynamics scientist Randy Hurd and his graduate adviser, Tadd Truscott, created a model of the male urethra on a 3D printer — a cylinder measuring 0.31 inches by 0.12 inches (8 millimeters by 3 millimeters). Before reaching the urinal walls, the urine stream broke up into individual droplets. The greatest pee splash occurred when the urine stream came in angled perpendicular to the urinal wall, down to about 45 degrees.

Recognizing Giant Leaps: Google Lunar XPRIZE Establishes Milestone Prizes (Op-Ed)

Alexandra Hall, senior director of the Google Lunar XPRIZE, contributed this article to SPACE.com's Expert Voices: Op-Ed & Insights. Back in 2007, building upon the successes of the Ansari XPRIZE for suborbital spaceflight and the Northrop Grumman Lunar Lander Challenge, XPRIZE and Google launched the $30 million Google Lunar XPRIZE, the largest incentivized competition to date. This week, XPRIZE and Google announced a series of Milestone Prizes available to competing teams. Over the past decade, XPRIZE has successfully launched and awarded a number of competitions, learning a great deal about what makes for optimum prize design.

Giant Moon-Forming Impact On Early Earth May Have Spawned Magma Ocean

LONDON — Billions of years ago, the Earth's atmosphere was opaque and the planet's surface was a vast magma ocean devoid of life. This scenario, says Stanford University professor of geophysics Norman Sleep, was what the early Earth looked like just after a cataclysmic impact by a planet-size object that smashed into the infant Earth 4.5 billion years ago and formed the moon. The moon, once fully formed, which would have appeared much larger in the sky at the time, since it was closer to Earth

4 Secrets of Creativity from Pixar's President

SAN DIEGO — If anyone knows about creativity, it's Ed Catmull. The president of Pixar and Walt Disney Animation Studios in Emeryville, Calif., has spent a lifetime bringing richly imaginative stories to life on the silver screen, from "Toy Story" to "Wall-E." His personal trajectory took him from graduate school in computer science, to working for George Lucas, to leading Pixar and Disney animation.

Health 'Score' on Food Packages May Help Consumers Make Healthier Choices

For people trying to wade though nutrition labels and choose healthy options, a front-of-package food label that boils down nutrition information to a single "score" may be the most user-friendly approach, a new study suggests. In recent years, the fronts of some food packages have been decorated with short food labels, which are intended to briefly summarize a product's nutrition, and make unhealthy ingredients (such as high levels of saturated fat) highly visible to consumers. However, there is currently no standard for what information needs to be on these labels, leading to a variety of front-of-package food labeling systems that may confuse consumers, said study researcher Christina A. Roberto, a psychologist and epidemiologist at the Harvard School of Public Health. The new study attempted to help answer this question by comparing five front-of-package food labeling systems, as well as packages with no label.

Can You Give HPV to Yourself?

One potential risk factor for getting oral infections with the human papillomavirus (HPV) may have been overlooked by researchers: giving it to yourself. In a new study, women who engaged in behaviors that could potentially transfer HPV from their genitals to their mouths were nearly four times more likely to have an oral HPV infection than those who did not engage in such behaviors. (Presumably, women would need to already have an HPV infection in their genitals for such a transfer to occur.) The results held even after the researchers took into account other behaviors that could increase the women's risk of oral HPV infection, such as their number of oral sex partners.

People with Depression May Age Faster

People suffering from depression may be aging faster than other people, according to a new study from the Netherlands. In the study of about 1,900 people who had major depressive disorders at some point during their lives, along with 500 people who had not had depression, researchers measured the length of cell structures called telomeres, which are "caps" at the end of chromosomes that protect the DNA during cell division. Normally, telomeres shorten slightly each time cells divide, and their length is thought to be an index of a cell's aging. The researchers found telomeres were shorter in people who had experienced depression compared with people in the control group.

Big Brother: Streetlights That Watch and Listen

They look like ordinary streetlights, shining down on Las Vegas sidewalks after the sun has set. But Sin City's new streetlights have a few special capabilities that have civil libertarians up in arms. The city is installing Intellistreets, a brand of street lighting that is capable of recording video and audio of pedestrians and motorists. What happens in Vegas, it seems, no longer stays in Vegas.

Underwater Mission by Jacques Cousteau's Grandson Postponed

How Typhoon Haiyan Compares to the 2004 Tsunami

Super Typhoon Haiyan ravaged the central Philippines on Friday (Nov. 8), affecting millions and displacing hundreds of thousands. It will likely go down as one of the five strongest storms in the last 50 years, even though estimates of the storm's strength vary, said Brian McNoldy, a tropical storm expert at the University of Miami. Jeff Weber, a researcher at the University Corporation for Atmospheric Research in Boulder, Colo., put Haiyan in the top three strongest storms, as measured by wind speed at landfall. "The last time I saw something of this scale was in the aftermath of the Indian Ocean tsunami," said Sebastian Rhodes Stampa, the head of a United Nations disaster assessment team that visited the area on Saturday, according to The New York Times.

11/12/13: What Makes Today So Special?

Perhaps it's only notable for spawning a midweek blitz of weddings or a rush to buy lucky lotto tickets, or being a good day for Count von Count. A David's Bridal survey estimated that more than 3,000 brides would get married today across the United States — a 722 percent increase compared with this Tuesday last year. "Iconic dates have become a trend in the United States, reaching new heights when over 65,000 couples tied the knot on 07/07/07," Brian Beitler, chief marketing officer for David's Bridal, said in a statement.

How the Brain Creates Out-of-Body Experiences

The findings, presented here Sunday (Nov. 10) at the annual meeting of the Society for Neuroscience, highlight which brain regions are active when a person has an out-of-body experience. The findings suggest the brain relies on a complex interplay of information from different senses to produce the experience of being inside of a body — even when it's someone else's.

New Type of Quasar Found, Baffling Scientists

Astronomers have discovered a new type of quasar — an incredibly bright galactic core powered by a supermassive black hole — that current theory fails to predict. The newly found quasars do demonstrate this behavior, but, surprisingly, some of the gas also appears to be falling back to the center, researchers said. "Matter falling into black holes may not sound surprising," study lead author Patrick Hall, an astronomer at York University in the United Kingdom, said in a statement. Gas flow in and around quasars can be calculated by examining its Doppler shift, or the change in the wavelengths of light that are produced as the gas moves.

Satellite likely incinerated after re-entering Earth's atmosphere: officials

By Irene Klotz ORLANDO, Florida (Reuters) - A large science satellite that mapped Earth's gravity likely re-entered the atmosphere where most of it incinerated on Sunday, about three weeks after running out of fuel and beginning to lose altitude, officials said. Ground tracking stations' last contact with Europe's Gravity field and steady-state Ocean Circulation Explorer, or GOCE, was at 5:42 p.m. (2242 GMT) as it passed 75 miles above Antarctica, Heiner Klinkrad, head of the European Space Agency's space debris office, wrote in a status report posted on the European Space Agency's website. The official designation of space is the Karman line, 62 miles above Earth. About 25 percent of the car-sized satellite was expected to have survived re-entry, with debris most likely falling into the ocean, European Space Agency officials said.

International space crew returns Olympic torch to Earth

A Soyuz capsule carried an International Space Station crew of three back to Earth on Monday along with an Olympic torch that was displayed in open space as part of Russia's preparations for the Sochi 2014 Winter Games. Slowed by parachutes and braking rockets fired to soften the impact, the Soyuz TMA-09M hit the Kazakh steppe on schedule at about 8:49 a.m. (0249 GMT) after a more than three-hour descent from the space station, live footage on Russian and NASA TV showed. "The Olympic torch is home after a four-day journey," an announcer on NASA TV said after what he called a flawless descent. Cosmonauts Oleg Kotov and Sergei Ryazansky had taken an unlit silver-and-grey torch, inspired by the Firebird of Russian folklore, on a spacewalk on Saturday, the first time an Olympic torch has been in open space.

Soyuz Spacecraft Carrying Olympic Torch, Crew of 3 Returns to Earth

A Russian Soyuz space capsule landed safely on the steppe of Kazakhstan Sunday (Nov. 10), returning cosmonauts and two astronauts to Earth along with a one other precious item: the Olympic torch. The Soyuz spacecraft landed at 9:49 p.m. EST (0249 Nov. 11 GMT) under a clear blue sky in central Kazakhstan, where the local time was Monday morning. Frigid temperatures greeted the returning space travelers — cosmonaut Fyodor Yurchikhin, NASA astronaut Karen Nyberg and Italian astronaut Luca Parmitano — after five and a half months in space. "The initial reports indicate a bull's eye landing for the Soyuz TMA-09M spacecraft and its crew," NASA spokesman Rob Navias said during the agency's televised landing commentary.[See more landing day photos for Soyuz crew]

1-ton European Satellite Falls to Earth in Fiery Death Dive

A European satellite met its fiery doom in Earth's atmosphere late Sunday (Nov. 10), succumbing to the same gravitational pull of the planet that it spent the last four years mapping like never before. The European Space Agency's GOCE satellite fell from space Sunday at 7 p.m. EST (0000 Nov. 11 GMT) while flying on a path that would take it over Siberia, the Western Pacific Ocean, the eastern Indian Ocean and Antarctica, ESA officials said.

Incredible Technology: How to Launch Superfast Trips to Mars

New propulsion technologies may blast astronauts through space at breakneck speeds in the coming decades, making manned Mars missions much faster and safer. Souped-up electric propulsion systems and rockets driven by nuclear fusion or fission could end up shortening travel times to the Red Planet dramatically, proponents say, potentially opening up a new era in manned space exploration. "Using existing rocket fuels, it's nearly impossible for humans to explore much beyond Earth," John Slough of the University of Washington, leader of a team developing a fusion-driven rocket, said in a statement earlier this year. Putting boots on the Red Planet is a chief ambition of NASA, which aims to send astronauts to the vicinity of Mars by the mid-2030s.

From Space Cooking to Disaster Plans: Astronaut Chris Hadfield Reveals Cosmic Life Lessons (Video)

NEW YORK — You'd be hard-pressed to catch astronaut Chris Hadfield unprepared. Years earlier, during his grueling jet training to become a fighter pilot for the Canadian military, Hadfield would drive the desolate roads of Saskatchewan to familiarize himself with the landscape that he'd be flying over during critical tests — tests he knew might make or break his shot at becoming an astronaut, even though Canada didn't have a space program at the time.

Best Age for Woman's First Child? 25, Poll Finds

Most Americans think the best time for a woman to have her first child is at age 25 or younger, whereas most think first-time dads should be 26 or older, according to a new Gallup poll. The timing of life milestones such as marriage and parenthood has shifted over the years. There are biological reasons to have children earlier rather than later. Women are most fertile in their late teens and early 20s, and older dads confer increased risks for schizophrenia, autism and other mental health disorders onto their children, according to a 2011 study in the journal Translational Psychiatry.

Veterans Bring the Whig Party Back

Though you may remember it from high-school history class, the Whig Party gave America some of the most utterly forgettable presidents of the 1800s. (If the names Millard Fillmore, Zachary Taylor and John Tyler fail to inspire much patriotic fervor in you, you're not alone.) Nonetheless, a new Whig Party — calling itself the Modern Whig Party, or MWP — has risen from the ashes of history and is poised for a comeback. Robert "Heshy" Bucholz, a card-carrying MWP member, was elected last week as an election judge in Philadelphia, making him the first Whig to win any elected office in the city since 1854, according to Philly.com.

Smuggled Chinese Artifacts Lead to Charges

A Florida art dealer is facing heavy fines and possible prison time in connection with an ancient artifact smuggling case. Francois B. Lorin, 74, of Winter Park, was hit with obstruction of justice charges after he forged documents in an attempt to legitimize an illegal shipment of ancient Chinese objects, federal authorizes allege. U.S. Customs and Border Protection discovered the artifacts in Miami, Fla., in June 2011. They detained the shipment from Hong Kong "due to inconsistencies between the shipping documentation and physical examination," said a spokesperson with U.S. Immigration and Customs Enforcement (ICE).

Snakes Control Blood Flow to Boost Vision

At least for one snake species, when the slitherer feels threatened, it controls the blood flow to its eyes to ensure that its sight is unobstructed, a new study found. The research focused on the coachwhip snake (Masticophis flagellum), a thin, nonvenomous species that is found across the United States and Mexico and can range in color from brown to pink. While examining the eye of a coachwhip snake, study researcher Kevin van Doorn, of the University of Waterloo in Canada, said he noticed a network of blood vessels in this see-through layer of skin. He found that the blood vessels constricted and expanded in a consistent cycle while the snakes were resting so that blood cells wouldn't pool up in front of the animals' eyes and obscure their already limited vision.

By the Numbers: 5 Cultural Facts About Veterans

Today, Veterans Day, men and women in uniform are being honored for the service to the country. As the Civil War was winding down, President Abraham Lincoln called on Americans in his second inaugural address "to care for him who shall have borne the battle and for his widow, and his orphan." While returning and fallen servicemembers have long been revered in the United States, Veterans Day was only established as a national holiday in 1919, though at the time it was called Armistice Day, celebrating the anniversary of the end of World War I. The Veterans History Project of the American Folklife Center aims to collect, preserve and make accessible veterans' personal stories from as far back as World War I to more recent conflicts in Iraq and Afghanistan. According to the U.S. Census Bureau, there were 1.6 million female veterans in the nation in 2012.

Babies Named After Dads: Which States Have More (And Why)

Dale Earnhardt Jr., was one. So was Martin Luther King Jr. And who could forget Harry Connick Jr.? In the United States, southern and western states are strongly influenced by honor culture ethics, thanks to immigration by the Scotch-Irish, scientists say. "Sometimes culture plays a hidden or subtle role in the kinds of names we're attracted to," said study researcher Ryan Brown, a psychologist at the University of Oklahoma.

Electron Appears Spherical, Squashing Hopes for New Physics Theories

Job Interview Advice for Veterans: Practice

A new study from Military Benefit Association revealed that half of the veterans recently separated from the U.S. military and are currently unemployed have not had a full- or part-time job since leaving the military. Roy Gibson, a retired U.S. Air Force Senior Master Sgt. and president of the Military Benefit Association, said one critical aspect to landing new work for veterans is ensuring they are well-prepared for the job search process, including any interviews they may go on. When going on an interview, it is important that veterans can accurately describe their skills and what they can bring to the table. Gibson said research shows that more than 70 percent of hiring managers find it difficult to ascertain recent veterans' skill sets based on their resume alone.

Cosmonauts Wore Special Space Patch for Olympic Torch Spacewalk

The two cosmonauts who took an Olympic torch on a spacewalk outside of the International Space Station Saturday (Nov. 9) carried out the symbolic relay wearing a surprise space mission patch depicting the icon of the 2014 Winter Games. Oleg Kotov and Sergey Ryazanskiy with Russia's federal space agency Roscosmos each donned Orlan spacesuits adorned with the previously unseen embroidered emblem, which, like the Olympic Games, came as the result of an international effort. "The patch is done in bold colors and in a bit of a 'comic book' style," wrote Dutch artist Luc van den Abeelen, who designed the patch together with space patch enthusiast Jacques van Oene, in an e-mail to collectSPACE.com. "It shows a cosmonaut on a spacewalk in heavy perspective, with the Olympic torch prominently sticking out toward the viewer." [Photos: See the 2014 Winter Olympic Torch in Space]

Catholic Education No Better Than Public Schooling, Study Suggests

Catholic schools don't provide a better education than public schools, at least when it comes to basics like math and reading, new research suggests. Children at Catholic schools don't improve their math or reading scores on standardized tests across elementary school and don't show better behavioral outcomes than public school children, according to the study, which will be published in a forthcoming issue of the Journal of Urban Economics. "Across many outcomes, both academic and behavioral, we don't find anything that seems to point to a real benefit of Catholic schools over public schools," study co-author Todd Elder, an economist at Michigan State University, said in a statement. Many an adult remembers sitting through classes taught by Catholic priests and nuns, and more than 2 million children are currently enrolled in one of 6,700 Catholic schools across the country, according to the National Catholic Educational Association.

US to Destroy 6 Tons of Ivory This Week

In a first, U.S. officials are going to destroy their massive stockpile of illegal ivory this week, hoping to send a zero-tolerance message to elephant poachers. On Thursday (Nov. 14), the U.S. Fish and Wildlife Service (FWS) will pulverize nearly 6 tons (5.4 tonnes) of illegal ivory items, from whole tusks to tiny trinkets, which have been seized over the past 25 years as a result of smuggling busts and criminal investigations. The ivory crush will take place at the Rocky Mountain Arsenal National Wildlife Refuge in Commerce City, Colo., just outside of Denver. After that, the objects can be used to educate the public and train law enforcement officials.

Scientists expect satellite crash next week

BERLIN (AP) — The European Space Agency says its GOCE research satellite will crash to Earth on Sunday night or during the day on Monday, but debris is unlikely to cause any casualties.

Doomed European Satellite May Fall to Earth Tonight, But Where?

A European satellite at the end of its mission is expected to fall out of space tonight. According to European Space Agency predictions, the falling GOCE satellite could to Earth sometime Sunday night (Nov. 10) or early Monday. "The satellite is at an altitude of 147 km (91 miles), dropping at a rate of more than 1 km (0.6 miles) an hour," ESA's GOCE spacecraft operations manager Christoph Steiger wrote in a status update today, adding that the atmospheric drag on the satellite is too high to measure. ESA scientists expect 25 to 45 fragments of the satellite to survive the fiery re-entry through Earth's atmosphere.

Space Station Crew and Olympic Torch Return to Earth Tonight: Watch Live

A Russian Soyuz space capsule will bring the Olympic torch and three residents of the International Space Station back to Earth tonight (Nov. 10) and you can watch the landing live online. The Soyuz TMA-09M spacecraft is due to land on the steppes of Kazakhstan in Central Asia at 9:49 p.m. EST (0249 Nov. 11 GMT) to return NASA astronaut Karen Nyberg, Italian astronaut Luca Parmitano and Russian cosmonaut Fyodor Yurchikhin home after a 5 1/2-month mission in orbit. The trio will also return the Olympic torch to Earth ahead of the 2014 Winter Olympics Games in Sochi, Russia. You can watch the Soyuz landing webcast live here, courtesy of NASA TV.

3 Tips for Getting into an Exercise Groove

Many everyday activities, such as home repairs and gardening may be as good as exercise, according to an October British Journal of Sports Medicine study. These are small actions, but they may give you the momentum you need to keep going.

New Laser Tech Could Detect and Destroy Brain Diseases

A new technology that uses only light could one day detect and annihilate disease-causing proteins in the brain, researchers say. The method involves using lasers to distinguish between normal brain tissue and the abnormal tissue found in people with Alzheimer's disease, Parkinson's disease and Creutzfeldt-Jakob disease (the human form of mad cow disease). The laser technique — which has not yet been tested in animals — might one day be able to treat people with these diseases, researchers report. "Using just a source laser, we can distinguish between proteins in the amyloid structure and those functioning properly," said study researcher Piotr Hanczyc, a biophysicist at the Chalmers University of Technology in Sweden.

The 7 Deadly Sins of Networking

Whether it's online through social media sites or offline at industry events, there's a good chance that anyone you connect with can either help you directly or put you in touch with someone else who can. Mike Muhney, CEO of mobile relationship management purveyor vipOrbit, warned that while social media is incredibly powerful and useful in networking, it can also hurt your ability to create professional and personal connections if you don't utilize it well.

Changing the Way You Think About Change

Chris Majer — founder and CEO of The Human Potential Project, a Washington State-based management and leadership consulting firm — thinks of change as a never-ending cycle of learning. Armed with this definition, Majer has helped corporate clients (AT&T, Microsoft, Intel) and various military agencies (Army, Navy, Marines) break down the barriers that keep change at bay, so that these organizations can achieve greater success. In the second-edition release of his book, "The Power to Transform: Passion, Power and Purpose in Daily Life" (Rodale Books, September 2013), Majer shares the methods that he has developed over several decades for bringing about meaningful changes in his clients' personal and professional lives. Chris Majer: Transformation is simply a rapid amount of change in a short amount of time.
