The camera study is the first remote-camera scent-station survey conducted within the Chernobyl Exclusion Zone, or CEZ.

Exfoliating thinner flakes of phosphorene at higher yield

Posted: 18 Apr 2016 01:13 PM PDT

By deoxygenating water, researchers discovered a new way to exfoliate phosphorene into atomically thin flakes. In order for phosphorene to reach its full potential, it needs to be incredibly thin -- preferably at the atomic scale. Until now, researchers have experienced difficulties in exfoliating atomically thin flakes from the bulk material, called black phosphorus, in a quick and efficient manner.

Trees' internal water pipes predict which species survive drought

Posted: 18 Apr 2016 01:13 PM PDT

Tree species that can withstand stress to the water-transport system that carries water from the roots to the crown are less susceptible to drought and massive die-off. The findings could help forestry experts, especially in the American West, create early-warning systems and take precautionary steps to reduce a forest's vulnerability to drought.

Nanoparticle acts like Trojan horse to halt asthma

Posted: 18 Apr 2016 01:10 PM PDT

In a new approach to treating asthma and allergies, a biodegradable nanoparticle acts like a Trojan horse, hiding an allergen in a friendly shell, to convince the immune system not to attack it, according to new research. As a result, the allergic reaction in the airways is shut down long- term and an asthma attack prevented. The technology can be applied to food allergies as well and is currently being tested in a mouse model of peanut allergy, similar to food allergy in humans.

New computer program can help uncover hidden genomic alterations that drive cancers

Posted: 18 Apr 2016 11:55 AM PDT

Cancer is rarely the result of a single mutation in a single gene. Rather, tumors arise from the complex interplay between any number of mutually exclusive abnormal changes in the genome, the combinations of which can be unique to each individual patient. To better characterize the functional context of genomic variations in cancer, researchers have developed a new computer algorithm they call REVEALER.

New technique to probe 'noise' in quantum computing

Posted: 18 Apr 2016 10:06 AM PDT

Quantum computing may revolutionize information processing by providing a means to solve problems too complex for traditional computers, with applications in code breaking, materials science and physics, but figuring out how to engineer such a machine remains elusive. Now researchers have devised a new way to 'sense' and control external noise in quantum computing.

American teacher panel surveys teachers' knowledge, perceptions of state standards

Posted: 18 Apr 2016 10:06 AM PDT

Asynchronous cell cycle phase key to critical stage of animal embryonic development

Posted: 18 Apr 2016 10:06 AM PDT

The synchronous mitosis of early embryonic development switches to a patterned form at the 11th cell division following removal of a cell cycle compensatory mechanism, new research shows. An asynchronous S-phase length is masked by a compensatory asynchronous G2-phase length up to the 11th mitosis, after which the transition to spatial patterning occurs. These findings help in understanding the link between mitotic timing and embryonic development.

Researchers find method that could resurrect an abandoned pancreatic cancer targeted drug

Posted: 18 Apr 2016 09:27 AM PDT

Pancreatic cancer is on track to become the second leading cause of cancer-related deaths by 2020. These statistics are due, in part, to pancreatic cancer's resistance to most targeted cancer therapies. Working with pancreatic cancer cells, researchers have now found a mechanism that could be responsible for the cancer's resistance to at least one targeted approach. If the results hold true in animal models and eventually clinical trials, the approach could help researchers develop more effective combination therapies and breathe new life into forgotten and failed cancer drugs.

Bigger brains led to bigger bodies in our ancestors

Posted: 18 Apr 2016 09:07 AM PDT

New research suggests that humans became the large-brained, large-bodied animals we are today because of natural selection to increase brain size. The work contradicts previous models that treat brain size and body size as independent traits. Instead, the study shows that brain size and body size are genetically linked and that selection to increase brain size will 'pull along' body size.

Researchers can identify you by your brain waves with 100 percent accuracy

Posted: 18 Apr 2016 09:06 AM PDT

Shining light on brain tumors

Posted: 18 Apr 2016 09:05 AM PDT

When operating on cancer, surgeons want to remove tumors and not healthy tissue. This is especially important and challenging when dealing with brain tumors, which are often spread out and mixed in with the healthy tissue. Researchers have shown that a well-established optics technique can reveal exactly where brain tumors are, producing images in less than a minute -- unlike conventional methods that can take a whole day.

Tuberculosis bacteria build 'edible' havens in immune cells

Posted: 18 Apr 2016 09:05 AM PDT

Bacteria that cause tuberculosis trick immune cells meant to destroy them into hiding and feeding them instead, report scientists. The study results revolve around the ancient battle between the human immune system and bacterial invaders, where immune cells strive to recognize bacteria as the microbes work to evade them. Mycobacterium tuberculosis remains the leading bacterial cause of death globally because, like other successful pathogens (e.g. HIV), it goes beyond evasion to take over functions of immune cells.

A space 'spider' watches over young stars

Posted: 18 Apr 2016 09:05 AM PDT

A nebula known as "the Spider" glows fluorescent green in an infrared image from NASA's Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS). The Spider, officially named IC 417, lies near a much smaller object called NGC 1931, not pictured in the image. Together, the two are called "The Spider and the Fly" nebulae. Nebulae are clouds of interstellar gas and dust where stars can form.

Posted: 18 Apr 2016 09:03 AM PDT

A new study tries to disentangle the complex question of whether rising amounts of carbon dioxide in the air might in some cases help crops. It suggests that while greater warmth will reduce yields of some, higher carbon dioxide could help mitigate the effects in some regions, unless other complications of global warming interfere.

Brain caught 'filing' memories during rest

Posted: 18 Apr 2016 09:01 AM PDT

Memories formed in one part of the brain are replayed and transferred to a different area of the brain during rest, according to a new study in rats.The finding suggests that replay of previous experiences during rest is important for memory consolidation, a process whereby the brain stabilizes and preserves memories for quick recall in the future. Understanding the physiological mechanism of this is essential for tackling amnesiac conditions such as Alzheimer's disease, where memory consolidation is affected.

Brain scans link physical changes to cognitive risks of widely used class of drugs

Posted: 18 Apr 2016 09:01 AM PDT

Posted: 18 Apr 2016 06:51 AM PDT

Removing an immunomodulatory protein called osteopontin improves the symptoms of mice with muscular dystrophy by changing the type of macrophages acting on damaged muscle tissue, according to a new paper. The study adds support to the idea that osteopontin inhibitors could be used to treat patients with Duchenne muscular dystrophy.

Neonicotinoid seed treatments produce higher soybean yields in the Southern US

Posted: 18 Apr 2016 06:51 AM PDT

Treating soybean seeds with neonicotinoid pesticides (imidacloprid or thiamethoxam) provides higher yields in southern US states, scientists have found. The results of their study contrast with a 2014 report from the US Environmnental Protection Agency, which stated that neonicotinoid seed treatments offered no economic benefits.
