Present-day lithium batteries are efficient but involve a range of resource and environmental problems. Now, using materials from alfalfa and pine resin and a clever recycling strategy, researchers have come up with an interesting alternative.
Using ecstasy significantly affects a person’s ability to detect faces, shapes and patterns,...
Anti-odor clothing may not be living up to its promise, and a researcher is saying it could all...
California farmers who spray a widely used insecticide on some of the state's most abundant crops may soon have to overcome the nation's steepest restrictions or find another pest killer, officials said this week. Regulators are proposing heavy restrictions— but not an all-out ban— on chlorpyrifos, used to treat crops like grapes and almonds.
The World Health Organization says there should be thousands of doses of experimental Ebola vaccines available in the coming months and they could eventually be given to health care workers and other people who have had contact with the sick.
Concrete is the world’s most used construction material and a leading contributor to global warming, producing as much as one-tenth of industry-generated greenhouse gas emissions. Now, a new study suggests a way in which those emissions could be reduced by more than half— and the result would be a stronger, more durable material.
The various patterns that atoms of a solid material can adopt, called crystal structures, can have a huge impact on its properties. Being able to accurately predict the most stable crystal structure for a material has been a longstanding challenge for scientists.
Future generations of miners could harvest metals from trees, capitalizing on the ability of some plants to isolate and accumulate metals in their shoots. Plants that can extract metals, such as nickel or cobalt, from the soil could be harvested for significant returns.
Concerns that fluids from hydraulic fracturing, or “fracking,” are contaminating drinking water abound. A new study has found that discharge of fracking wastewaters to rivers, even after passage through wastewater treatment plants, could be putting the drinking water supplies of downstream cities at risk.
Researchers are reporting a new inexpensive and simple way to make transparent, flexible transistors— the building blocks of electronics— that could help bring roll-up smartphones with see-through displays and other bendable gadgets to consumers in just a few years.
Scientists have developed a novel one-step process using, for the first time in these types of syntheses, potassium superoxide to rapidly form oxide nanoparticles from simple salt solutions in water.
New government-approved labeling on Pfizer's drug Chantix suggests that the anti-smoking medication may not carry the risks of suicidal behavior that first earned it the Food and Drug Administration's strongest warning more than five years ago.
Chemists have reported a breakthrough in techniques to develop new drugs in the fight against diseases such as cancer and Alzheimer’s. The team has developed an innovative process allowing them to generate a particular type of synthetic amino acid— and a particular type of designer protein— that has not been done before.
The liver provides critical functions, such as ridding the body of toxins. Its failure can be deadly, and there are few options for fixing it. But, scientists are reporting a way to potentially inject stem cells from tonsils, a body part we don’t need, to repair damaged livers— all without surgery.
Antibiotics revolutionized health care in the early 20th century, helping kill bacteria that once killed thousands of people. But bacteria are constantly outsmarting science, and new strains of antibiotic-resistant bacteria are popping up more frequently.
Scientists have scoured cow rumens and termite guts for microbes that can efficiently break down plant cell walls for the production of next-generation biofuels, but some of the best microbial candidates actually may reside in the human lower intestine.
The smell of cut grass in recent years has been identified as the plant’s way of signaling distress, but new research says the aroma also summons beneficial insects to the rescue.
Thanks to new LEGO-like components, it is now possible to build a 3-D microfluidic system quickly and cheaply by simply snapping together small modules by hand.
Researchers have discovered a way to create a highly sensitive chemical sensor based on the crystalline flaws in graphene sheets. The imperfections have unique electronic properties that the researchers were able to exploit to increase sensitivity to absorbed gas molecules by 300 times.
It's the first day of autumn, and the telltale signs are here: crisp weather, pumpkin spice lattes and, most importantly, the leaves are changing colors.
Scientists have generated a new star-shaped molecule made up of interlocking rings, which is the most complex of its kind ever created. Known as a “Star of David” molecule, scientists have been trying to create one for over a quarter of a century.
Researchers have developed a chip capable of simulating a tumor's "microenvironment" and plan to use the new system to test the effectiveness of nanoparticles and drugs that target cancer. The new system, called a tumor-microenvironment-on-chip device, will allow researchers to study the complex environment surrounding tumors and the barriers that prevent the targeted delivery of therapeutic agents.
U.S. Sens. Chris Coons, Susan Collins, Jay Rockefeller and Johnny Isakson have introduced the Sustainable Chemistry Research and Development Act of 2014, which creates a cohesive plan to fund research into sustainable chemistry, improve coordination between federal agencies and boost commercialization of sustainable technologies.
Shellfish such as mussels and barnacles secrete very sticky proteins that help them cling to rocks or ship hulls, even underwater. Inspired by these natural adhesives, a team of engineers has designed new materials that could be used to repair ships or help heal wounds and surgical incisions.
Researchers have created a small-scale hydrogen generator that uses light and a two-dimensional graphene platform to boost production of the hard-to-make element. The research also unveiled a previously unknown property of graphene. The two-dimensional chain of carbon atoms not only gives and receives electrons, but can also transfer them into another substance.
Ensuring that corn absorbs the right balance of nitrogen, phosphorus and potassium is crucial to increasing global yields. A review of data from more than 150 studies from the U.S. and other regions showed that high yields were linked to production systems in which corn plants took up key nutrients at specific ratios— nitrogen and phosphorus at a ratio of five-to-one and nitrogen and potassium at a ratio of one-to-one.
Corrosion resistance and high strength put stainless steel high on the list of essential materials for satellite and rocket designers. Now, ESA plans to investigate an alternative, environmental-friendly method of readying this important metal.
A wild berry native to North America may strengthen the effectiveness of a chemotherapy drug commonly used to treat pancreatic cancer. A new study suggests that adding nutraceuticals to chemotherapy cycles may improve the effectiveness of conventional drugs, particularly in hard to treat cancers.
