Scientists have discovered a new molecule that can join together chains of amino acids. Only three other known molecules have been discovered to perform this function, which is an important process in the development of new drugs. A key difference is that the new molecule can do the same process 10,000 times faster than the other three and “cleanly,” without leaving any residue behind.
Scientists have developed new geochemical tracers that can identify hydraulic fracturing flow...
Researchers working toward the technology of the future are interested in the origin of life. If...
Researchers have created a cellular probe that combines a tarantula toxin with a fluorescent compound to help scientists observe electrical activity in neurons and other cells. The probe binds to a voltage-activated potassium ion channel subtype, lighting up when the channel is turned off and dimming when it is activated.
In a new study a researcher at Arizona State Univ.'s Biodesign Institute examines the trajectory of chemicals appearing as emergent threats to human or environmental health. The study reveals that around 14 years typically elapse from the onset of initial safety concerns about a given chemical to the height of concern and appropriate action. This extended timeline implies protracted exposure to CECs for a large number of people.
In a design that mimics a hard-to-duplicate texture of starfish shells, Univ. of Michigan engineers have made rounded crystals that have no facets. The process used to manufacture them—organic vapor jet printing—might lend itself to 3D-printing medications that absorb better into the body and make personalized dosing possible.
Scientists have combined hydrogen with its heavier sibling deuterium—which has an added neutron in its nucleus—and created a novel, disordered, "Phase IV"-material where the molecules interact differently than have been observed before.
Several types of plastic pipes in eco-friendly green buildings in the United States have been found to leach chemicals into drinking water that can cause odors and sometimes exist at levels that may exceed health standards.
New research will help batteries resist overcharging, improving the safety of electronics from cellphones to airplanes. This work focused on the design, synthesis and testing of organic compounds that can be incorporated into the electrolytes of lithium-ion batteries to improve their safety profiles.
Fruit flies can identify odors from illicit drugs and explosive substances almost as accurately as wine odor, which the insects are naturally attracted to because it smells like their favorite food, fermenting fruit.
Each day, plankton rise from deep underwater to the ocean's surface during the night and then return to the depths in daytime. Zoologists describe this movement as Earth’s biggest migration. The stimulus for this mass migration has long puzzled scientists but it may be the sleep hormone melatonin.
Using a common laboratory filter paper decorated with gold nanoparticles, researchers have created a unique platform, known as “plasmonic paper,” for detecting and characterizing even trace amounts of chemicals and biologically important molecules— from explosives, chemical warfare agents and environmental pollutants to disease markers.
A geochemist studying Samoan volcanoes has found evidence of the planet’s early formation still trapped inside the Earth. Known as hotspots, volcanic island chains such as Samoa can hold ancient primordial signatures from the early solar system that have somehow survived billions of years.
Researchers have developed a new catalyst, by mixing inexpensive iron with a tiny amount of rare palladium, which could lead to making biofuels cheaply and more efficiently.
Researchers have designed a family of materials to make LEDs that don’t include rare earths but instead are made out of copper iodide, which is an abundant compound. They tuned them to glow a warm white shade or various other colors using a low-cost solution process.
The EPA has approved a new version of a popular weed killer to be used on genetically modified corn and soybeans. The EPA says that it will allow the use of a 2,4-D weed killer called Enlist Duo.
Alcohol consumption isn't the only thing a breath analysis can reveal. Scientists have been studying its possible use for diagnosing a wide range of conditions in humans— and now in the beloved bottlenose dolphin.
Arsenic, a well-known poison, can be taken out of drinking water using sophisticated treatment methods. Now, scientists have come up with a new low-cost, simple way to remove arsenic using leftovers from another known health threat— cigarettes.
Scientists have taken proteins from nerve cells and used them to create a “smart” material that is extremely sensitive to its environment. This marriage of materials science and biology could give birth to a flexible, sensitive coating that is easy and cheap to manufacture in large quantities.
Researchers looked at how protein molecules in the blood of insects function in insects' immune system. Pest may be sickened to learn to that the scientists have discovered a genetic mechanism that helps compromise their immune system.
A university is playing a key role in an international project to develop a radical new type of nuclear power station that is safer, more cost-effective, more compact and much quicker and less disruptive to build than any previously constructed. Researchers are exploring whether the element thorium could help to meet the new design’s fuel needs.
Poison control workers say that as the e-cigarette industry has boomed, the number of children exposed to the liquid nicotine that gives hand-held vaporizing gadgets their kick also has spiked. More than 2,700 people have called poison control this year to report an exposure to liquid nicotine, over half of those cases in children younger than six.
A team of researchers has pioneered the world’s first fluorescent sensor to rapidly identify the presence of fat in milk. When the light purplish sensor is mixed with a milk sample, it transmits fluorescent signals of orange hues instantly under light when fat is detected, with brighter shades when the concentration of fat in the milk sample increases.
Results of a small clinical trial suggest that a chemical derived from broccoli sprouts— and best known for claims that it can help prevent certain cancers— may ease classic behavioral symptoms in those with autism spectrum disorders.
Chemists have synthesized a ferromagnetic superconducting compound that is amenable to chemical modification, opening the route to detailed studies of this rare combination of physical properties.
Scientists have developed ultra-fast-charging batteries that can be recharged up to 70 percent in only two minutes. The new generation batteries also have a long lifespan of over 20 years, more than 10 times compared to existing lithium-ion batteries.
In spite of its dangerous reputation, cholesterol is in fact an essential component of human cells. Manufactured by the cells themselves, it serves to stiffen the cell’s membrane, helping to shape the cell and protect it. By mapping the structure of a key enzyme involved in cholesterol production, researchers have gained new insight into this complex molecular process.
Scientists have developed a slurry-based process that can revolutionize carbon capture. The slurry, consisting of a porous powder suspended in glycol, offers the efficient large-scale implementation of a liquid while maintaining the lower costs and energy efficiency of solid carbon-capturing materials.
