There is no cure for Alzheimer's disease and other forms of dementia, but the research community is one step closer to finding treatment.

'Wetting' a battery's appetite for renewable energy storage
Sun, wind and other renewable energy sources could make up a larger portion of the electricity America consumes if better batteries could be built to store the intermittent energy for cloudy, windless days. Now a new material could allow more utilities to store large amounts of renewable energy and make the nation's power system more reliable and resilient.

Turtles are well known for their longevity and protective shells, but it turns out these reptiles use sound to stick together and care for young, according to the Wildlife Conservation Society and other organizations.

Pygmy phenotype developed many times, adaptive to rainforest
The small body size associated with the pygmy phenotype is probably a selective adaptation for rainforest hunter-gatherers, according to an international team of researchers, but all African pygmy phenotypes do not have the same genetic underpinning, suggesting a more recent adaptation than previously thought.

Climate Change Will Threaten Fish by Drying Out Southwest U.S. Streams, Study Predicts
Fish species native to a major Arizona watershed may lose access to important segments of their habitat by 2050 as surface water flow is reduced by the effects of climate warming, new research suggests.

An embryonic cell's fate is sealed by the speed of a signal
When embryonic cells get the signal to specialize the call can come quickly. Or it can arrive slowly. Now, new research from Rockefeller University suggests the speed at which a cell in an embryo receives that signal has an unexpected influence on that cell's fate.

Applying new cholesterol guidelines to a patient population reduces heart attacks, strokes, study finds
A study from UT Southwestern researchers found that recently introduced cholesterol guidelines would significantly reduce new cardiovascular events, when compared to treatment based on previous cholesterol guidelines.

Zebrafish help to unravel Alzheimer's disease
New fundamental knowledge about the regulation of stem cells in the nerve tissue of zebrafish embryos results in surprising insights into neurodegenerative disease processes in the human brain. A new study by scientists at VIB and KU Leuven identifies the molecules responsible for this process.

Researchers inspired by marine life to design camouflage systems
It could be a fun party trick - put your cell phone down on a table and watch it fade into the woodwork - or part of a lifesaving technology used by industry or the military.

Trees and shrubs invading critical grasslands, diminish cattle production
Half of the Earth's land mass is made up of rangelands, which include grasslands and savannas, yet they are being transformed at an alarming rate.

Antibodies, together with viral 'inducers,' found to control HIV in mice
Although HIV can now be effectively suppressed using anti-retroviral drugs, it still comes surging back the moment the flow of drugs is stopped. Latent reservoirs of HIV-infected cells, invisible to the body's immune system and unreachable by pharmaceuticals, ensure that the infection will rebound after therapy is terminated.

More than just X and Y: A new genetic basis for sex determination
