Cellular contamination pathway for plutonium, other heavy elements, identified

Scientists find that an iron-binding protein can transport actinides into cells


Scientists at Lawrence Berkeley National Laboratory have reported an advance in understanding the biological chemistry of radioactive metals, opening up new avenues of research into strategies for remedial action in the event of possible human exposure to nuclear contaminants. Research led by ...


Scientists are first to see elements transform at atomic scale

Byproduct of research may lead to new way to irradiate cancer with gold-bonded isotopes


Chemists at Tufts University's School of Arts and Sciences, collaborating with PerkinElmer and UCL (University College London), have witnessed atoms of one chemical element morph into another for the first time ever - a feat that produced an unexpected outcome that could lead to a new way to ...


Researchers learn how beryllium causes deadly lung disease


Using exquisitely detailed maps of molecular shapes and the electrical charges surrounding them, researchers at National Jewish Health have discovered how the metal beryllium triggers a deadly immune response in the lungs. In Cell John Kappler, PhD, and his colleagues show how a genetic ...


Flexible supercapacitor raises bar for volumetric energy density

Could be woven into clothes to power wearable medical, communications devices


Scientists have taken a large step toward making a fiber-like energy storage device that can be woven into clothing and power wearable medical monitors, communications equipment or other small electronics. The device is a supercapacitor—a cousin to the battery. This one packs an interconnected ...

Simple microfluidic devices now have valves


Researchers at the National Institute of Standards and Technology (NIST) have added yet another innovation—miniature valves—to their ever-growing collection of inexpensive, easy-to-manufacture and highly efficient microfluidic devices made from plastic films and double-sided tape. Traditionally, ...


A better way to make unnatural amino acids

The findings have potential applications in cancer, infectious disease, Alzheimer's drugs


Chemists at The Scripps Research Institute (TSRI) have devised a greatly improved technique for making amino acids not found in nature. These "unnatural" amino acids traditionally have been very difficult to synthesize, but are sought after by the pharmaceutical industry for their potential ...


Growing number of chemicals linked with brain disorders


Toxic chemicals may be triggering the recent increases in neurodevelopmental disabilities among children—such as autism, attention-deficit hyperactivity disorder, and dyslexia—according to a new study from Harvard School of Public Health (HSPH) and Icahn School of Medicine at Mount Sinai. The ...


A new wrinkle in the control of waves

Flexible materials could provide new ways to control sound and light


Flexible, layered materials textured with nanoscale wrinkles could provide a new way of controlling the wavelengths and distribution of waves, whether of sound or light. The new method, developed by researchers at MIT, could eventually find applications from nondestructive testing of materials to ...

Turkeys inspire smartphone-capable early warning system for toxins


Some may think of turkeys as good for just lunch meat and holiday meals. But bioengineers at the University of California, Berkeley, saw inspiration in the big birds for a new type of biosensor that changes color when exposed to chemical vapors. This feature makes the sensors valuable detectors ...


Personal care products are possible sources of potentially harmful parabens for babies


Through lotions, shampoos and other personal care products (PCPs), infants and toddlers are likely becoming exposed to potentially harmful substances, called parabens, at an even higher level than adult women in the U.S., researchers have reported. They published their findings on parabens, which ...
