Muslim immigrants who feel marginalized and discriminated against in countries that expect them to integrate into their culture and society are more likely to experience psychological threats to their own significance that could be related to increased support of radicalism, according to new research.

A new technique for evaluating drug safety is designed to be affordable and can detect stress on cells at earlier stages than conventional methods. It is the first with a fluorescent sensor that turns on when proteins begin to clump together -- an early sign of a process that occurs in Alzheimer's and other diseases.

Birds exhibit an extraordinary diversity of plumage pigmentation patterns. It has been overlooked, however, that complex patterns can be produced only with the contribution of melanins because these are the only pigments under direct cellular control.

Desert tortoises pace back and forth and can overheat by roadside fencing meant to help them, according to a study new study.

One big drawback to biosensors that measure sweat is you have to sweat. But researchers have come up with a new biosensor that can stimulate perspiration for days on just a tiny patch of skin.

A researcher has devised a new bee monitoring system to better understand what more than 20,000 honeybees housed in hives in a local field are 'saying' to each other -- looking for clues about their health.

Researchers have developed a set of tools to observe, monitor and quantify how misfolded proteins associated with Parkinson's disease enter neurons in laboratory cultures and what happens to them once they're inside.

A new drug zeroes in on mutated nuclear receptors found in cancer and leaves normal proteins alone.

Is extinction forever? Efforts are under way to use gene editing and other tools of biotechnology to "recreate" extinct species such as the woolly mammoth and the passenger pigeon. Could such "de-extinction" initiatives aid conservation by reviving species lost to habitat destruction and climate change? Or are they more likely to hinder conservation? What should the guiding ideals of conservation be in a new age of biotechnology? These are some of the questions addressed in a new report.

Astronomers like to say we are the byproducts of stars, stellar furnaces that long ago fused hydrogen and helium into the elements needed for life through the process of stellar nucleosynthesis. But what about the heavier elements in the periodic chart, elements such as gold, platinum and uranium? Astronomers believe most of these "r-process elements" -- elements much heavier than iron -- were created, either in the aftermath of the collapse of massive stars and the associated supernova explosions, or in the merging of binary neutron star systems.

By learning how a recently discovered immune cell works in the body, researchers hope to one day harness the cells to better treat allergies and infections.

Today's 3-D printers have a resolution of 600 dots per inch, which means that they could pack a billion tiny cubes of different materials into a volume that measures just 1.67 cubic inches. Such precise control of printed objects' microstructure gives designers commensurate control of the objects' physical properties. But evaluating the physical effects of every possible combination of even just two materials, for an object consisting of tens of billions of cubes, would be prohibitively time consuming. A new software lets designers exploit this issue of extremely high resolution.

By using concurrent design and nanomanufacturing, researchers produce inexpensive material surfaces for use in ultra-thin solar cells that can absorb more light.

Platelets, the cells in blood that enable clotting, are highly reliant on their ability to metabolize glucose, according to a new study.

Rhesus macaques previously infected with dengue or yellow fever viruses appear to be neither more nor less susceptible to severe infection with Zika virus, according to new research.
