 US Military Aids Recovery in Typhoon-Ravaged Philippines Read More » 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.

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.

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.

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.

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. Read More »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.

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.

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.

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.

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.

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.
