A group of ecotoxicologists is arguing that the EPA’s current practices for evaluating pesticide safety are inadequate and likely to result in decisions biased toward industry interests.
Researchers have engineered the harmless gut bacteria E. coli to generate renewable propane. The development is a step toward commercial production of a source of fuel that could one day provide an alternative to fossil fuels.
Researchers working to save the Amazon are developing a new and more effective version of biochar made from native Amazonian bamboos. The process creates a fine-grained, highly porous charcoal that makes it possible to grow crops and other plants in areas that have been stripped of trees or contaminated with heavy metals from mining.
The chemical uniformity of stars in the same cluster is the result of turbulent mixing in the clouds of gas where star formation occurs, according to a study by astrophysicists. Their results show that even stars that don't stay together in a cluster will share a chemical fingerprint with their siblings, which can be used to trace them to the same birthplace.
A fortuitous collaboration has led to the total synthesis of a recently discovered natural antibiotic. The laboratory recreation of a fungus-derived antibiotic, viridicatumtoxin B, may someday help bolster the fight against bacteria that evolve resistance to treatments in hospitals and clinics around the world.
Federal researchers next week will start testing humans with an experimental vaccine to prevent the deadly Ebola virus. The National Institutes of Health announced that it is launching the safety trial on a vaccine developed by the agency's National Institute of Allergy and Infectious Diseases and GlaxoSmithKline.
A number of leading international researchers have recommended that fluorochemicals are only used where they are absolutely essential, until better methods exist to measure the chemicals and more is known about their potentially harmful effects.
Ebola is a rare, but deadly disease that exists as five strains, none of which have approved therapies. One of the most lethal strains is the Sudan ebolavirus (SUDV). Now, researchers are reporting a possible therapy that could someday help treat patients infected with SUDV.
New evidence puts into doubt the long-standing belief that a deficiency in serotonin— a chemical messenger in the brain— plays a central role in depression. Scientists are reporting that mice lacking the ability to make serotonin in their brains did not show depression-like symptoms.
A Southern California food company has recalled nearly 93,000 pounds of fully cooked chicken Caesar salad kits sold nationwide over concerns of possible listeria contamination.
Few ingredients come with as much baggage as monosodium glutamate. More commonly known as MSG, the compound has had a bad reputation for nearly 50 years. So, chemists felt it was time to clear its name.
Researchers have created a CMOS-compatible, biomimetic color photodetector that directly responds to red, green and blue light in much the same way the human eye does.
Today, Japan announced it is ready to provide a Japanese-developed anti-influenza drug as a possible treatment for the rapidly expanding Ebola outbreak. Chief Cabinet Secretary Yoshihide Suga told reporters that Japan can offer favipiravir, developed by a subsidiary of Fujifilm Holdings Corp., at any time at the request of the World Health Organization.
For centuries poppy plants have been grown to provide opium, the compound from which morphine and other important medicines, such as oxycodone, are derived. Now, bioengineers have hacked the DNA of yeast, reprograming these simple cells to make opioid-based medicines via a sophisticated extension of the basic brewing process that makes beer.
A revolutionary new scientific method will improve the diversity of biologically active molecules, such as antibiotics and anti-cancer agents. Scientist took their inspiration from evolution in nature. Their research may uncover new pharmaceutical drugs that traditional methods would never have found.
Many people think of crystals as little more than sparkly things behind glass cases in museums. But crystals are everywhere, from the dinner table to the human body.
The onset of Alzheimer’s disease can be slowed and some of its symptoms curbed by a natural compound that is found in pomegranate. Also, the painful inflammation that accompanies illnesses such as rheumatoid arthritis and Parkinson’s disease could be reduced.
Scientists need to understand the mechanisms that control the conversion of organic soil carbon into CO2 gas. Until now, researchers believed that bacteria were largely responsible. But, new research shows that sunlight, not microbial activity, dominates the production of CO2 in Arctic inland waters.
Scientists have developed a low-cost, emissions-free device that uses an ordinary AAA battery to produce hydrogen by water electrolysis. The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas.
Thanks to new insights into the details of photosynthetic water splitting, the prospects for the development of clean fuels based on water and sunlight are improving.
The fluorine that is found in products such as toothpaste was likely formed billions of years ago in now dead stars of the same type as our sun.
Your chairs, synthetic rugs and plastic bags could one day be made out of cocoa, rice and vegetable waste rather than petroleum, scientists are now reporting. The novel process they have developed could help the world deal with its agricultural and plastic waste problems.
When certain sunblock ingredients wash off skin and into the sea, they can become toxic to some of the ocean’s tiniest inhabitants, which are the main course for many other marine animals.
Where the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers. The researchers evaluated an emerging method of power generation, called pressure retarded osmosis, in which two waters of different salinity are mixed to produce energy.
As anyone who has bitten into a chili pepper knows, its burning spiciness— though irresistible to some— is intolerable to others. Scientists exploring the chili pepper’s effect are using their findings to develop a new drug candidate for many kinds of pain, which can be caused by inflammation or other problems.
