Using a powerful data-crunching technique, researchers have sorted out how a protein keeps defective genetic material from gumming up the cellular works.
Protein synthesis is the most important cellular function. The initiation of this process is the most regulated and most critical component, but it is still the least understood. Now, research has unlocked the genetic scanning mechanism that begins this crucial piece of cell machinery.
Detecting HIV/AIDS, tuberculosis, malaria and other deadly infectious diseases as early as possible helps to prevent their rapid spread and allows for more effective treatments. Now, a new nanotechnology method— employing common, everyday shrink wrap— may make highly sensitive, extremely low-cost diagnosis of infectious disease agents possible.
Heat waves could significantly reduce crop yields and threaten global food supply if climate change is not tackled and reversed. This is according to a new study that has, for the first time, estimated the global effects of extreme temperatures and elevated levels of carbon dioxide on the production of maize, wheat and soybean.
A new advanced assay platform “lights up” pathogenic bacteria, such as listeria, E. coli and salmonella, for quick detection on foods and vegetables. The assay uses biological particles called bacteriophages, or phages, which only target bacteria.
A Texas taste testing found that the key to the favorite Lone Star State’s vodkas is in the dissolved salts in the water used for each brand.
When cancer spreads from one part of the body to another, it becomes even more deadly. It moves with stealth and can go undetected for months or years. But, a new technology that uses “nanoflares” has the potential to catch these lurking, mobilized tumor cells early.
A new kind of single-dose vaccine that comes in a nasal spray and doesn’t require refrigeration could dramatically alter the public health landscape— get more people vaccinated around the world and address the looming threats of emerging and re-emerging diseases.
The health benefits of eating dark chocolate have been extolled for centuries, but the exact reason has remained a mystery. Now, researchers are reporting that certain bacteria in the stomach gobble the chocolate and ferment it into anti-inflammatory compounds that are good for the heart.
While the world’s best athletes competed during the winter Olympics, scientists were waging a battle behind the scenes to make sure no one had an unfair advantage from banned performance-enhancing drugs. Now, researchers have unveiled a new weapon— a test for doping compounds that is a thousand times more sensitive than those used today.
Researchers have succeeded in producing uniform antimony nanocrystals. Tested as components of laboratory batteries, they are able to store a large number of both lithium and sodium ions.
Materials for lightweight construction, protective clothing or sports equipment can be produced at high temperatures and high pressures, say chemists. This process is faster, better and more eco-friendly than other techniques.
A research project at a new biosecurity level 2 pilot plant facility is working to create validated processes that the spice industry could use to assure that Salmonella on whole black peppercorns and cumin seeds is eliminated.
As some countries and companies roll out new rules to limit animal testing in pharmaceutical products designed for people, scientists are stepping in with a new way to test therapeutic drug candidates and determine drug safety and drug interactions— without using animals.
Chicken fat, pork fat or beef fat— none is the cornerstone of a healthful diet— but animal fats, including those from alligators, could give an economical, ecofriendly boost to the biofuel industry, according to researchers who reported a new method for biofuel production.
Researchers say a new color-changing smart tag can tell consumers whether a carton of milk has turned sour or a can of green beans has spoiled without opening the containers.
Molecular dynamics simulations often take too long to be practical for simulating chemical processes that occur on long timescales. Now, scientists have shown that time integration algorithms working in parallel can significantly speed up computationally demanding molecular dynamics simulations.
It won't be nearly as much fun as eating candy bars, but a big study is being launched to see if pills containing the nutrients in dark chocolate can help prevent heart attacks and strokes.
A sweetener created from the plant used to make tequila could lower blood glucose levels for the 26 million Americans and others worldwide who have type 2 diabetes and help them and the obese lose weight, researchers say.
A study may lead to more efficient water-desalination systems and a fundamental understanding of fluid flow.
Plants have many functions: they provide food and fuel, release the oxygen that we breathe and add beauty to our surroundings. Now, researchers want to make plants even more useful by augmenting them with nanomaterials that could enhance their energy production and give them completely new functions, such as monitoring environmental pollutants.
Honey, that delectable condiment for breads and fruits, could be one sweet solution to the serious, ever-growing problem of bacterial resistance to antibiotics.
A waste product from making paper could yield a safer, greener alternative to the potentially harmful chemical BPA, now banned from baby bottles but still used in many plastics.
Scientists reported they have created at least five new experimental substances— based on a tiny protein found in cone snail venom— that could someday lead to the development of safe and effective oral medications for treatment of chronic nerve pain.
Adjusting the calcium level and acidity could be the key to developing new better-tasting, more eye-appealing and creamier reduced-fat sauces, desserts and salad dressings that could be on the market soon, researchers are reporting.
