Scientists have successfully created magnetic bacteria that could be added to foodstuffs and could, after ingestion, help diagnose diseases of the digestive system like stomach cancer. These important findings constitute the first use of a food as a natural drug and aid in diagnosing an illness, anywhere in the world.
Two widely used neonicotinoids— a class of insecticide— appear to significantly harm honey bee colonies over the winter, particularly during colder winters, according to a new study. The study replicated a 2012 find from the same research group.
The ability to create conducting polymer films in a variety of shapes, thicknesses and surface properties rapidly and inexpensively will make growing and testing cells easier and more flexible.
Researchers have developed materials that not only heal, but regenerate. Until now, self-repairing materials could only bond tiny microscopic cracks. The new regenerating materials fill in large cracks and holes by regrowing material.
Forensic scientists are still trying to match thousands of bone slivers from the remains of people who died in the World Trade Center on Sept. 11, 2001 to DNA from the more than 1,000 victims who never came home and have never been identified.
Researchers have devised a novel cancer treatment that destroys tumor cells by first disarming their defenses, then hitting them with a lethal dose of DNA damage. In studies with mice, the team showed that this one-two punch, which relies on a nanoparticle that carries two drugs and releases them at different times, dramatically shrinks lung and breast tumors.
A French research team figured out that, by looking at the carbon atoms in mummies that lived in Egypt between 3500 B.C. and 600 A.D., you could find out what they ate. They learned that, if you're a vegetarian, tucking in along the Nile thousands of years ago would have felt just like home.
New research revealed that a plant hormone once believed to promote flower formation in annual plants also plays a role in inhibiting flowers from forming. The dual role of this hormone, gibberellin, could be exploited to produce higher-yielding crop plants.
Researchers, working to produce ethanol from plant material, are taking a hard look at eucalyptus as a possible source for the clean fuel. The team recently switched the focus of their lab-scale research from sugarcane and sorghum to eucalyptus.
Mother Nature's helper in turning nitrogen from the air into ammonia is an enzyme called nitrogenase that uses molybdenum and iron. Now, scientists want to learn natural catalyst's secrets and apply them to synthetic catalysts.
Research may help in the fight against terrorism with the creation of a sensor that can detect tiny quantities of explosives with the use of light and special glass fibers.
Peptide amphiphiles are an emerging class of molecules that can be designed for novel therapies in advanced medicine.
Converting methane into hydrogen is crucial for clean energy and agriculture. This reaction requires water and a catalyst. Now, researchers have used a novel laser approach to control specific vibrations of a water molecule, which can affect the efficiency of the reaction.
Humans use more than 100 million tons of plastics annually. Now, scientists are turning by-products of wood and wool into biodegradable packaging to help slash global plastic consumption.
Scientists have developed a model that can help perfumers predict how various combinations of chemicals will smell.
A new video highlights the chemistry behind a pregnant woman's altered sense of taste and smell, how mom's diet influences baby's favorite foods and other pregnancy phenomena.
At the elevated levels of atmospheric CO2 anticipated by around 2050, crops that provide a large share of the global population with most of their dietary zinc and iron will have significantly reduced concentrations of those nutrients.
Research shows that new catalysts, which remove oxygenated compounds from bio-derived oils, may lead to better and cheaper renewable biofuels.
While flexible gadgets such as “electronic skin” and roll-up touch screens are moving ever closer to reality, their would-be power sources are either too wimpy or too stiff. A new energy device provides enough energy and flexibility for tomorrow’s bendable devices.
A research team, using tunable luminescent nanocrystals as tags to advance medical and security imaging, have successfully applied them to high-speed scanning technology and detected multiple viruses within minutes.
Nerve agents are among the world's most feared chemical weapons, but scientists have demonstrated a way to engineer carbon nanotubes to dismantle the molecules of a major class of these chemicals. In principle, they say, the nanotubes could be woven into clothing that destroys the nerve agents on contact before they reach the skin.
As worker bees get older, their roles change from nursing and cleaning the hive to guarding and foraging. Now, researchers have found that the amounts of two substances vary by time and location in the brains of the honeybees in a way that mirrors the timing of their changing roles.
Researchers have developed a new antibacterial fabric that can kill a range of infectious bacteria within 10 minutes. The discovery could significantly reduce the risk of deadly hospital-acquired infections and revolutionize the way the medical industry deals with infection control.
Anthrax occupies a special role as a feared and potentially lethal disease, but the culmination of a 10-year research project has identified a section of its toxin that could produce an effective new vaccine.
Researchers have created an organ-on-a-chip that reproduces the structure, functions and cellular make-up of bone marrow, a complex tissue that until now could only be studied intact in living animals.
