Vulnerable grassland birds abandon mating sites near wind turbines
Shifting to renewable energy sources has been widely touted as one of the best ways to fight climate change, but even renewable energy can have a downside, as in the case of wind turbines' effects on bird populations.
Shifting winds: An early warning for reduced energy
The Rocky Mountains certainly aren't known for their mild winters. But in contrast to the upper Midwest, which seems to exist in a perpetually frozen state from November through March, the plains just east of the Rockies do get an occasional reprieve from the bitter cold: the Chinook winds.
Biodiversity promotes multitasking in ecosystems
A new study of the complex interplay between organisms and their environment shows that biodiversity--the variety of organisms living on Earth--is even more important to the healthy functioning of ecosystems than previously thought.
A practical gel that simply 'clicks' for biomedical applications
If you opt to wear soft contact lenses, chances are you are using hydrogels on a daily basis. Made up of polymer chains that are able to absorb water, hydrogels used in contacts are flexible and allow oxygen to pass through the lenses, keeping eyes healthy.
Gravity data show that Antarctic ice sheet is melting increasingly faster
During the past decade, Antarctica's massive ice sheet lost twice the amount of ice in its western portion compared with what it accumulated in the east, according to Princeton University researchers who came to one overall conclusion -- the southern continent's ice cap is melting ever faster.
New gene editing tools force renewed debate over therapeutic germline alteration
Recent evidence demonstrating the feasibility of using novel CRISPR/Cas9 gene editing technology to make targeted changes in the DNA of human embryos is forcing researchers, clinicians, and ethicists to revisit the highly controversial issue of altering the inherited human genome.
Role of telomeres in plant stem cells discovered
The role played by telomeres in mammalian cells has been known for several years. It is also known that these non-coding DNA sequences, which are found at the ends of the chromosomes, protect them and are necessary to ensure correct cell division.
Substantial benefits for health and environment through realistic changes to UK diets
Making a series of relatively minor and realistic changes to UK diets would not only reduce UK diet-related greenhouse gas emissions by nearly a fifth, but could also extend average life expectancy by eight months, according to new research led by the London School of Hygiene & Tropical Medicine.
Fossils inform marine conservation
The fossil record helps to predict which kinds of animals are more likely to go extinct. When combined with information about hotspots of human impacts and climate-change predictions, Smithsonian scientists and colleagues pinpoint animal groups and geographic areas of highest concern for marine conservation in the May 1 issue of Science magazine.
How some beetles produce a scalding defensive spray
Bombardier beetles, which exist on every continent except Antarctica, have a pretty easy life. Virtually no other animals prey on them, because of one particularly effective defense mechanism: When disturbed or attacked, the beetles produce an internal chemical explosion in their abdomen and then expel a jet of boiling, irritating liquid toward their attackers.
Telomere changes predict cancer
A distinct pattern in the changing length of blood telomeres, the protective end caps on our DNA strands, can predict cancer many years before actual diagnosis, according to a new study from Northwestern Medicine in collaboration with Harvard University.
NOAA, Tulane identify second possible specimen of 'pocket shark' ever found
A very small and rare species of shark is swimming its way through scientific literature. But don't worry, the chances of this inches-long vertebrate biting through your swimsuit is extremely slim, because if you ever spotted one you'd be the third person to ever do so.

If you thought that a beetle with a machine gun built into its rear end was something that only exists in sci-fi movies, you should talk to Wendy Moore at the University of Arizona.
The appeal of being anti-GMO
A team of Belgian philosophers and plant biotechnologists have turned to cognitive science to explain why opposition to genetically modified organisms (GMOs) has become so widespread, despite positive contributions GM crops have made to sustainable agriculture.
Study finds guidance improves food safety practices at school, community gardens
School and community gardens have become increasingly popular in recent years, but the people managing and working in these gardens are often unfamiliar with food safety practices that reduce the risk of foodborne illness.
Sustainability progress should precede seafood market access, researchers urge
Demand for seafood from wild fisheries and aquaculture around the world has nearly doubled over the past four decades.
Study shows replacing 1 serving of sugary drink per day by water or unsweetened tea or coffee cuts risk of type 2 diabetes

New stem cell may overcome hurdles for regenerative medicine
Scientists at the Salk Institute have discovered a novel type of pluripotent stem cell--cells capable of developing into any type of tissue--whose identity is tied to their location in a developing embryo.
Holy agility! Keen sense of touch guides nimble bat flight
Bats fly with breathtaking precision because their wings are equipped with highly sensitive touch sensors, cells that respond to even slight changes in airflow, researchers have demonstrated for the first time.

Crowdsourced science helped predict the path of a deadly plant disease over a six-year period, demonstrating the contributions that trained citizen scientists can make in large-scale geographic tracking projects.
Spinal cord axon injury location determines neuron's regenerative fate
Researchers at University of California, San Diego School of Medicine report a previously unappreciated phenomenon in which the location of injury to a neuron's communication wire in the spinal cord -- the axon -- determines whether the neuron simply stabilizes or attempts to regenerate.
Buyers with a trade-in get a raw deal
If you're in the market for a new car, and especially if you have a trade-in, the latest research from the USC Marshall School of Business marketing department suggests you aren't getting the deal you think you are getting.
Mammals not the only animals to feed embryo during gestation
How and when does mom feed her embryo? We humans, like most mammals, experience pregnancy where a mother supplies nutrition directly to the embryo as it develops. But we're in the minority.

Viruses: You've heard the bad -- here's the good
In sharp contrast to the gastrointestinal distress it causes in humans, the murine (mouse infecting) norovirus plays a role in development of the mouse intestine and its immune system, and can actually replace the beneficial effects of certain gut bacteria when these have been decimated by antibiotics.
