Parts of the primordial soup in which life arose have been maintained in our cells today. Research reveals how cells in plants, yeast and very likely also in animals still perform ancient reactions thought to have been responsible for the origin of life- some four billion years ago.
Could the body's own immune system play a role in memory impairment and cognitive dysfunction...
A researcher has developed a method that uses X-rays for the rapid identification of substances...
According to the World Health Organization, 3.4 million people die from water-related diseases every year. A research team spent a year researching a membrane filter and developing a prototype. What makes the DrinkPure filter unique is that you can screw it on to virtually any plastic bottle. It doesn't require a pump or a reservoir.
Security forces worldwide rely on sophisticated equipment, trained personnel, and detection dogs to safeguard airports and other public areas against terrorist attacks. A revolutionary new electronic chip with nano-sized chemical sensors is about to make their job much easier.
Spinach gave Popeye super strength, but it also holds the promise of a different power for a group of scientists: the ability to convert sunlight into a clean, efficient alternative fuel.
The head of the government lab that potentially exposed workers to live anthrax has resigned. Michael Farrell was head of the Centers for Disease Control and Prevention lab since 2009. He submitted his resignation Tuesday.
The popular culinary herbs oregano and rosemary are packed with healthful compounds, and now lab tests show they could work in much the same way as prescription anti-diabetic medication. Scientists found that how the herbs are grown makes a difference, and they also identified which compounds contribute the most to this promising trait.
Using the second fastest supercomputer in the world, a scientist at the U.S. Department of Energy’s Ames Laboratory is attempting to develop a more efficient process for purifying rare-earth materials.
Federal wildlife refuges in the Northwest and Hawaii will phase out a class of pesticides that are chemically similar to nicotine because they pose a threat to bees and other pollinators key to crop growth.
HIV-infected people carry many different HIV viruses and all have distinct personalities—some much more vengeful and infectious than others. Yet, despite the breadth of infectivity, roughly 76 percent of HIV infections arise from a single virus. Now, scientists believe they can identify the culprit with very specific measurements of the quantities of a key protein in the HIV virus.
Over 150 years since it was first described by Darwin, scientists are finally uncovering the secrets behind the super strength of barnacle glue. Still far better than anything we have been able to develop synthetically, barnacle glue— or cement— sticks to any surface, under any conditions.
The danger of reporting findings before peer review is that scientists often can’t talk about the details of their research, which can lead to hype or fear in the media.
Two attorneys general from the Northwest have sued the companies responsible for the popular 5-Hour Energy drink. The suits allege the companies engaged in deceptive advertising and that 5-Hour Energy falsely claims customers get extra energy and focus from a unique blend of ingredients, when the boost actually comes from a concentrated dose of caffeine.
A biochemist’s discovery of a class of anti-viral small molecules that target the function of a virus DNA hidden in the infected livers of hepatitis B patients may lead to a cure for this viral infection that kills more than 600,000 people annually.
In the presence of charged substances, H2O molecules favor associating with elements with a negative electrical charge rather than a positive electric charge. Researchers have published a study on the subject that could provide new insights on the processes of cell formation.
Scientists haven't solved every potential problem with fracking. But they are working to replace many of the chemicals in the fluid, which contains sand, biocides, mineral-dissolving acids and more.
Scientists have discovered certain stink bug pheromone components and made them artificially in the lab for the first time. These substances can be used to monitor and manage their populations.
In this video, ACS examines four scientific facts about money. Did you know those dollar bills in your pocket have a hint of cocaine on them? Or that there are hidden inks and features to prevent counterfeiting? These are just a couple fascinating facts about money to make you scientifically richer.
Popping the blisters on the bubble wrap might be the most enjoyable thing about moving. Now, scientists propose a more productive way to reuse the packing material— as a sheet of small, test tube-like containers for medical and environmental samples. Their report shows that analyses can take place right in the bubbles.
Chemists and students in science and engineering have created a new type of chemical test, or assay, that’s inexpensive, simple and can tell whether or not one of the primary drugs being used to treat malaria is genuine– an enormous and deadly problem in the developing world.
If you’ve ever tried to watch a video on a tablet on a sunny day, you know you have to tilt it at just the right angle to get rid of glare or invest in a special filter. But, scientists are reporting that they’ve developed a novel glass surface that reduces both glare and reflection, which continue to plague even the best mobile displays today.
A three-dimensional porous nanostructure would have a balance of strength, toughness and the ability to transfer heat, which could benefit nanoelectronics, gas storage and composite materials that perform multiple functions.
Researchers have discovered a soybean gene whose mutation affects plant stem growth, a finding that could lead to the development of improved soybean cultivars for the northern U.S.
Scientists have shown how the main psychoactive ingredient in cannabis, THC, could reduce tumor growth in cancer patients. Research reveals the existence of previously unknown signaling platforms that are responsible for the drug’s success in shrinking tumors.
Researchers have invented a cheap, portable, microchip-based test for diagnosing type-1 diabetes that could speed up diagnosis and enable studies of how the disease develops. The test could improve patient care worldwide and help researchers better understand the disease.
Researchers have developed a technology that could overcome a major cost barrier to make clean-burning hydrogen fuel, which could replace expensive and environmentally harmful fossil fuels. The new technology is a novel catalyst that performs almost as well as cost-prohibitive platinum for electrolysis reactions, which use electric currents to split water molecules into hydrogen and oxygen.
How can the age of archeological objects be determined if the well-established carbon dating method does not apply— for example with metal objects? Scientists have introduced an electroanalytical method for dating artifacts made of copper and bronze based on the voltammetry of microparticles.
