The second qualification test of the SLS boosters was a noisy, fiery success.
By combining data from Chandra and several other telescopes, astronomers have identified the true nature of an unusual source in the Milky Way galaxy. This discovery implies that there could be a much larger number of black holes in the...
Contrary to the opinions of some courts, it is easier to determine the truthfulness of a woman wearing a headscarf or even a veil that leaves only her eyes exposed than a woman wearing no head covering at all, according to research published by the American Psychological Association.
A small, squishy vehicle equipped with soft wheels rolls over rough terrain and runs under water. Future versions of the versatile vehicle might be suitable for search and rescue missions after disasters, deep space and planet exploration, and manipulating objects during magnetic resonance imaging (MRI), according to its creators.

A group of physicists in Russia has learned to use a personal computer for calculations of complex equations of quantum mechanics, usually solved with help of supercomputers. This PC does the job much faster.
Scientists report an interesting conclusion that could have major impacts on the future of nano-manufacturing. Their analysis for a model of the process of random sequential adsorption (RSA) shows that even a small imprecision in the position of the lattice landing sites can dramatically affect the density of the permanently formed deposit.
Camera-equipped smartphones, laptops and other devices make it possible to share ideas and images with anyone, anywhere, often in real-time. But in our cameras-everywhere culture, the risks of accidentally leaking sensitive information are growing. Show More Summary
An approved anti-HIV drug latches to the enzyme already responsible for about 80 percent of the cholesterol elimination from the human brain, report scientists. Obtained with a cutting-edge atom-substitution technology called hydrogen-deuterium exchange, the molecular roadmap shows how small amounts of the drug can kick the enzyme, called CYP46A1, into higher gear.
Satellite cells are stem cells found in skeletal muscles. While transplantation of such muscle stem cells can be a potent therapy for degenerative muscle diseases such as Duchenne muscular dystrophy, these cells tend to lose their transplantation efficiency when cultured in vitro. Show More Summary
Prostate cancer researchers have discovered biomarkers using non-invasive liquid biopsies to identify aggressive disease before surgery.
As oil palm production expands from Southeast Asia into Central Africa, a new study finds that converting Africa's forests into monoculture plantations could trigger significant carbon emissions unless governments enact mandatory policies regulating which forests can be cleared and how much remaining forest must be set aside for conservation.

Researchers are closer to solving a decade-old mystery after discovering that a set of genes they are studying play a key role in early human development.
Across the world, many schoolchildren under 10 are overweight. In the search for the cause of this phenomenon, fetal programming was put under scrutiny in new research. That the mother's diet might have some influence could not be confirmed...Show More Summary
Dishonesty not only damages relation between human beings, it can also have a devastating effect on the economy. Scientists have now found out that in markets for credence goods -- markets that require a high degree of trust -- there are also strong incentives for dishonest behavior.
A possible epigenetic link between the environment and pubertal timing has been discovered by researchers. To a large extent, pubertal timing is heritable, but the underlying genetic causes are still unexplained. Researchers have now...Show More Summary
For the first time, a field study shows that social time cues override influence of light and darkness in regulating the natural body clock of honeybees, highlighting the complexity of clock regulation in natural habitat
A new study has identified a gene signature that predicts poor survival from ovarian cancer. The study also identified genes which help the cancer develop resistance to chemotherapy -- offering a new route to help tackle the disease...
By using an innovative 3-D inkjet printing method, researchers have taken the biggest step yet in producing microscopic silk swimming devices that are biodegradable and harmless to a biological system.
Policy makers’ and public health officials’ proper reactions could hold down the total costs to U.S. GDP of an influenza outbreak. Otherwise, costs could be nearly double previous estimates, say experts in a new report.
Parental involvement is crucial to a child's development into an adult, but researchers are finding that crossing the line between supportive and too involved could indirectly lead to issues such as depression and anxiety for young adults.
