Sheepdogs use just two simple rules to round up large herds of sheep, scientists have discovered. The findings could lead to the development of robots that can gather and herd livestock, crowd control techniques, or new methods to clean up the environment.
An M&A frenzy that accounted for nearly $90 billion of equity set the pace for the first half of 2014 in the pharma and biotech sectors, but a slowdown in IPOs and six months of volatile market activity could tarnish the year’s shimmering start.
A study examining body mass index in a large clinical sample of children with Fetal Alcohol Spectrum Disorders has found that rates of excess weight/obesity are elevated in children with partial fetal alcohol syndrome.
Weight loss surgery can curb alterations in brain activity associated with obesity and improve cognitive function involved in planning, strategizing and organizing.
Among adolescents with depression seen in primary care, a collaborative care intervention that included patient and parent engagement and education resulted in greater improvement in depressive symptoms at 12 months than usual care.
Genomics researchers have unraveled the genetic code of the rapeseed plant, most noted for a variety whose seeds are made into canola oil. Broccoli, cauliflower, Brussels sprouts, Chinese cabbage, turnip, collared greens, mustard and canola oil are all different incarnations of the same plant genus, Brassica.
The Taung Child, South Africa’s premier hominin discovered 90 years ago, never ceases to transform and evolve the search for our collective origins. Now, researchers are casting doubt on theories that Australopithecus africanus shows the same cranial adaptations found in modern human infants and toddlers– in effect disproving current support for the idea that this early hominin shows infant brain development in the prefrontal region.
Governments should have tougher rules for electronic cigarettes— banning their use indoors and putting them off limits for minors— until more evidence can be gathered about their risks, the U.N. health agency said today.
The famous fictional detective Sherlock Holmes used a magnifying lens to reveal barely visible but important evidence. Astronomers are now combining the power of many telescopes on Earth and in space with a vastly larger form of cosmic lens to study a case of vigorous star formation in the early Universe.
Existing power plants around the world will pump out more than 300 billion tons of carbon dioxide over their expected lifetimes, significantly adding to atmospheric levels of the climate-warming gas.
The predominant strain of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) infecting people in Europe, the Middle East and northern Africa derived from a single sub-Saharan ancestor, a team of international researchers have reported.
A balance board accessory for a popular video game console can help people with multiple sclerosis reduce their risk of accidental falls. MRI scans showed that use of the Nintendo Wii Balance Board system appears to induce favorable changes in brain connections associated with balance and movement.
GE, Panasonic, Toshiba and Fujitsu—one can easily point out the similarities between these companies. They have long been recognized and heralded for their work in the electronics and semiconductor industry. However, given their recent investments, it’s possible that this editorial written 20 years down the road may reflect on these companies as agricultural powerhouses instead.
Russell Garwood, a research fellow at the Univ. of Manchester, England, worked with Jason Dunlop, a curator at the Museum für Naturkunde, Berlin, to create a video of the movements of an extinct arachnid. The arachnid was one of the first land predators and lived 410 million years ago. Garwood and Dunlop used exceptionally detailed fossils from the Natural History Museum in London to recreate its walking gait.
