A new solar material that has the same crystal structure as a mineral first found in the Ural Mountains in 1839 is shooting up the efficiency charts faster than almost anything researchers have seen before-and it is generating optimism that a less expensive way of using sunlight to generate electricity may be in our planet's future.
The research, published in the journal Oncotarget, explored tumour heterogeneity - where different cells have different appearances or their own DNA signatures within the same cancer. Such differences could make it difficult to design effective, targeted treatment strategies.
To avoid the need for geoengineering, which could have enormous unforeseen consequences, the international community should pursue increased deployment of nuclear power plants, which do not emit carbon dioxide, to address the climate crisis.
The most comprehensive study to date of the family of bacteria that causes whooping cough points to more effective vaccine strategies and reveals surprising findings about the bacteria's origin and evolution.
The shale gas boom has transformed the energy landscape in the U.S., but in some drier locations, it could cause conflict among the energy industry, residents and agricultural interests over already-scarce water resources, say researchers.
Previous studies have shown that proliferation of endogenous neural precursor cells cannot alone compensate for the damage to neurons and axons.
Scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified a protein complex that plays a critical but previously unknown role in learning and memory formation.
A novel imaging technique provides insights into the role of redox signaling and reactive oxygen species in living neurons, in real time.

A team of scientists led by a researcher from the Cancer Science Institute of Singapore (CSI Singapore) at the National University of Singapore has identified the cancer specific stem cell which causes gastric cancer.
Lowland South America, including the Amazon Basin, harbors most of the last indigenous societies that have limited contact with the outside world.
Inspired by the fist-like club of a mantis shrimp, a team of researchers led by University of California, Riverside, in collaboration with University of Southern California and Purdue University, have developed a design structure for composite materials that is more impact resistant and tougher than the standard used in airplanes.
A study of older adults at increased risk for Alzheimer's disease shows that moderate physical activity may protect brain health and stave off shrinkage of the hippocampus- the brain region responsible for memory and spatial orientation that is attacked first in Alzheimer's disease.
Using nanodot technology, Berkeley Lab researchers have demonstrated the first size-based form of chromatography that can be used to study the membranes of living cells.
Analyzing thousands of breeding bird surveys sent in by citizen scientists across the western United States and Canada over 35 years, wildlife researchers report that most of the 40 songbird species they studied shifted either northward or toward higher elevation in response to climate change, but did not necessarily do both.
Usually, chemical reactions just take their course, much like a ball rolling downhill. However, it is also possible to deliberately control chemical reactions: at the Vienna University of Technology, molecules are hit with femtosecond laser pulses, changing the distribution of electrons in the molecule.
Working with mice and rabbits, Johns Hopkins scientists have found a way to block abnormal cholesterol production, transport and breakdown, successfully preventing the development of atherosclerosis, the main cause of heart attacks and strokes and the number-one cause of death among humans.
Strenuous occupational physical activity in midlife increases the risk of mobility limitation in old age, whereas leisure-time physical activity decreases the risk.
Scientists at Rice University have created a nanoscale detector that checks for and reports on the presence of hydrogen sulfide in crude oil and natural gas while they're still in the ground.
Getting to the bottom of Alzheimer's disease has been a rapidly evolving pursuit with many twists, turns and controversies.
Last month, scientists announced the first hard evidence for cosmic inflation, the process by which the infant universe swelled from microscopic to cosmic size in an instant. This almost unimaginably fast expansion was first theorized more than three decades ago, yet only now has "smoking gun" proof emerged.
When mothers are exposed to trauma, illness, alcohol or other drug abuse, these stressors may activate a single molecular trigger in brain cells that can go awry and activate conditions such as schizophrenia, post-traumatic stress disorder and some forms of autism.
Children hear as much sophisticated information about animals when parents read picture book stories about animals as when they read flashcard-type animal vocabulary books, according to a new study from the University of Waterloo.
As evidence mounts showing the potential health benefits of probiotics, antioxidants and other nutritional compounds, more and more people are taking supplements.
Winsor Lowe, interim director of the University of Montana's Wildlife Biology Program, co-wrote a research paper published April 21 in the Proceedings of the National Academy of Sciences on how streamwater chemistry varies across a headwater stream network.
Like many social mammals, ravens form different types of social relationships - they may be friends, kin, or partners and they also form strict dominance relations.
