Chemo Timing is Key to Success

May 9, 2014 12:00 pm | by MIT, Anne Trafton | News | Comments

Researchers have devised a novel cancer treatment that destroys tumor cells by first disarming their defenses, then hitting them with a lethal dose of DNA damage. In studies with mice, the team showed that this one-two punch, which relies on a nanoparticle that carries two drugs and releases them at different times, dramatically shrinks lung and breast tumors.

Mummy Study Finds Ancient Egyptians Were Vegetarians

May 9, 2014 7:00 am | by Inside Science News Service, Alexander Hellemans | News | Comments

A French research team figured out that, by looking at the carbon atoms in mummies that lived in Egypt between 3500 B.C. and 600 A.D., you could find out what they ate. They learned that, if you're a vegetarian, tucking in along the Nile thousands of years ago would have felt just like home.

Hormone Has Dual Role in Flower Formation

May 9, 2014 7:00 am | by Univ. of Pennsylvania | News | Comments

New research revealed that a plant hormone once believed to promote flower formation in annual plants also plays a role in inhibiting flowers from forming. The dual role of this hormone, gibberellin, could be exploited to produce higher-yielding crop plants.

Eucalyptus May Be Source of Biofuel

May 9, 2014 7:00 am | by Univ. of Florida | News | Comments

Researchers, working to produce ethanol from plant material, are taking a hard look at eucalyptus as a possible source for the clean fuel. The team recently switched the focus of their lab-scale research from sugarcane and sorghum to eucalyptus.

Nature’s Secrets Can Improve Synthetic Catalysts

May 8, 2014 12:33 pm | by Pacific Northwest National Laboratory | News | Comments

Mother Nature's helper in turning nitrogen from the air into ammonia is an enzyme called nitrogenase that uses molybdenum and iron. Now, scientists want to learn natural catalyst's secrets and apply them to synthetic catalysts.

Light Can Detect Trace Amounts of Explosives

May 8, 2014 12:00 pm | by Univ. of Adelaide | News | Comments

Research may help in the fight against terrorism with the creation of a sensor that can detect tiny quantities of explosives with the use of light and special glass fibers.

Synthetic Peptides Can Influence Cell Survival

May 8, 2014 12:00 pm | by Advanced Photon Source | News | Comments

Peptide amphiphiles are an emerging class of molecules that can be designed for novel therapies in advanced medicine.

Scientists Harness Vibrations to Produce Hydrogen

May 8, 2014 7:00 am | by EPFL | News | Comments

Converting methane into hydrogen is crucial for clean energy and agriculture. This reaction requires water and a catalyst. Now, researchers have used a novel laser approach to control specific vibrations of a water molecule, which can affect the efficiency of the reaction.
