Technology May Save the Amazon

September 3, 2014 7:00 am | by Wake Forest Univ. | News | Comments

Researchers working to save the Amazon are developing a new and more effective version of biochar made from native Amazonian bamboos.

Research Finds Why Sibling Stars Look Alike

September 2, 2014 7:00 am | by UC Santa Cruz | Videos | Comments

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.

Synthesis Yields Natural Antibiotic

Scientists: Stop Non-essential Use of Fluorochemicals

August 28, 2014 7:00 am | by Technical Univ. of Denmark | News | Comments

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.

Potential Ebola Treatment May Help Contain Future Outbreaks

August 27, 2014 2:00 pm | by ACS | News | Comments

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.


Study Questions Long-held Depression Belief

August 27, 2014 2:00 pm | by ACS | News | Comments

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.

Company Recalls Possibly Contaminated Salad Kits

August 27, 2014 7:00 am | by Associated Press | News | Comments

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.

Chemists Debunk MSG Myths

August 26, 2014 7:00 am | by ACS | Videos | Comments

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.

Biomimetic Photodetector Sees Color

August 26, 2014 7:00 am | by Rice Univ. | News | Comments

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.

Japan Offers Flu Drug to Fight Ebola

August 25, 2014 2:00 pm | by Associated Press, Mari Yamaguchi | News | Comments

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.


Bioengineers Close to Poppy-free Opioid Painkillers

August 25, 2014 2:00 pm | by Stanford School of Engineering | News | Comments

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.

Mimicking Evolution Key to Improving Drug Diversity

August 25, 2014 7:00 am | by Univ. of Leeds | News | Comments

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.
