Singapore, Malaysia and northern Indonesia choked under a layer of toxic smog in September and October last year, caused by thousands of fires started in Indonesia to cheaply clear land for palm oil crops and for pulp and paper plantations. The study by scientists from the Netherlands, Britain and Indonesia, published in the online journal Scientific Reports recently, was the first scientific report calculating greenhouse gas emissions from the fires using measurements on the ground combined with satellite observations.

In a 5-3 decision, the court said that parts of law, which imposed a number of restrictions on abortion clinics, were unconstitutional. What did the Texas law require clinics to do?

Previous research on fish oil supplements and other sources of omega-3 fatty acids has shown mixed results, with some studies revealing heart-healthy benefits and others finding no benefit at all. The latest research, reported today (June 27) in the journal JAMA Internal Medicine, was the largest of its kind to measure the actual levels of omega-3 fatty acids in the participants' blood, as opposed to relying on questionnaires in which people report what they eat.

The idea holds that when people are "primed" or prompted to think about a particular concept — such as physical magnetic attraction — it affects their cognition in surprising ways. In this case, the magnets may make the metaphor of love as a physical force more prominent in people's minds, leading them to report closer feelings with their partners, said Andrew Christy, a graduate student in psychology at Texas A&M University and a co-author of the new study.

| Bat wings inspire new breed of drone By Matthew Stock The unique mechanical properties of bat wings could lead to a new breed of nature-inspired drone. A prototype built by researchers at the University of Southampton shows that membrane wings can have improved aerodynamic properties and fly over longer distances on less power. Using a paper-thin rubber membrane, the team designed wings that mimic the physiology of the muscles in a bat's wing, changing shape in response to the forces it experiences.

Python Caught in Circle of Own Molted Skin The serpent slithered around and around for about 3 hours until it eventually broke free, according to a reptile center in Australia. Stimson's pythons molt all the time, about once a month on average, but it's rare for one to get stuck in its sloughed-off skin, said David Penning, a doctoral fellow of biology at the University of Louisiana at Lafayette, who is not affiliated with the reptile center. "A young snake that's growing will shed more often than an older snake, because they're literally running out of space inside their skin," he said.

Normally, shooting stars form when particles in space — usually much smaller than an inch (just a few millimeters long) enter the atmosphere and burn brightly, in a process known as plasma emission. The company plans to launch a satellite carrying about 500 to 1,000 "source particles," which will become the artificial meteors.

Researchers surveyed almost 200 4-year-old girls and boys, as well as the children's mothers and teachers, to learn about each kid's Disney movie- and TV-watching habits, favorite princesses and playtime routines. "Girls who were into the princess culture at the first wave were more gender-stereotyped one year later," said study lead researcher Sarah Coyne, an associate professor of family life at Brigham Young University in Utah.

One earlier study of women, for example, found that the more attractive they considered a man to be, the more willing they would be to have unprotected sex with that man. Fifty-one heterosexual men completed a survey in which they were asked to rate the attractiveness of 20 women in photographs on a scale from 0 to 100.

Egg freezing is the process of extracting egg cells from a woman's ovaries and storing them for later use. Urayasu, a city near Tokyo, will provide the currency equivalent of $850,000 over a three-year period to fund a research project on egg freezing, according to the Associated Press.

The new research could lead to better robots, self-driving cars, data mining, medical diagnosis, stock-trading analysis and "other smart human-interactive systems and machines in the future," said Tae-Woo Lee, a materials scientistat the Pohang University of Science and Technology in Korea and senior author of the study. Previous research suggested that the brain has approximately 100 billion neurons and roughly 1 quadrillion (1 million billion) connections wiring these cells together.

Indeed, summer music festivals can be a perfect storm of heat, dehydration and drug use that can lead to deadly consequences. When it comes to drugs at these events, the biggest problem is ultimately the bad decision-making that goes hand-in-hand with drug use, said Dr. Lewis Nelson, a toxicologist and emergency medicine physician at New York University Langone Medical Center.

An eye exam showed her vision was normal, and she had no signs of a blood clot or other conditions that could cause short-term vision loss, the doctors said. This vision problem lasted about 15 minutes, and happened on and off for six months, the report said. Read More »Stomach Sucker: How Does New Weight-Loss Device Work? The Food and Drug Administration recently approved a weight-loss device that may sound like something out of a science-fiction movie: a small tube inserted into the stomach allows patients to drain a portion of their gut's contents before the body absorbs those calories. The device, called AspireAssist, was approved by the FDA after a year-long clinical trial on 171 people, 111 of whom underwent a procedure to place the device. But not all weight-loss experts think the device is a game-changer.

In these studies, the women took either a planted-based therapy, such as a supplement or herbal remedy, or a placebo to treat symptoms of menopause. The plant-based therapies included a class of compounds called phytoestrogens, which are found in certain foods, like soybeans. Read More » | ||||

| Male Fiddler Crabs Entrap Females In Their Bachelor Pads Read More » Memory-Boosting Trick: Exercise After Learning Researchers found that people who did a high-intensity workout on a spinning bike 4 hours after completing a memory task had better recall when they were retested two days later than men and women who pedaled the bike immediately after the task, and those who didn't exercise after the task at all, according to the findings published today (June 16) in the journal Current Biology. The study showed that delaying exercise by 4 hours after learning has a "moderate" effect on memory, said Dr. Guillen Fernandez, a professor of cognitive neuroscience at The Donders Institute for Brain, Cognition and Behavior at the Radboud University Medical Center in the Netherlands. The findings showed that exercise improves memory performance and changes the way memories are stored in the brain, said Fernandez, who conducted the research with Eelco van Dongen, a postdoctoral student at the institute, and other colleagues.

The percentage of Americans who ate what is considered to be an ideal diet remained low, however, increasing slightly from 0.7 percent in 1999 to 1.5 percent in 2012, according to the study, published today (June 21) in the journal JAMA. The researchers determined diet quality using a scoring system based on dietary recommendations from the American Heart Association (AHA).

The study, based on surveys of U.S. residents, found that most respondents would not want to ride in these vehicles themselves, and were not in favor of regulations enforcing utilitarian algorithms on driverless cars.

"When you blow a whistle, you hear something because the air oscillates — pulses in and out of the whistle — and radiates a wave," the study's lead author Chris Hughes, a researcher at the National Oceanography Centre in Liverpool, in the United Kingdom, told Live Science. "In this case, the water is pulsing in and out of the Caribbean Sea. Read More » | ||||
