Breaking the bond: To take part or not?

Physicists working have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

Injury alters their aroma — ScienceDaily

Some people watch the competition carefully for the slightest signs of weakness. Lemurs, on the other hand, just give them a sniff. These primates from Madagascar can tell that a fellow lemur is weaker just by the natural scents they leave behind, finds a study on ring-tailed lemurs led by Duke University researchers. Males act more aggressively toward scents that smell “off.” “Our study shows that physical injury from peers dampens an animal’s scent signature, and in a way that…

A new tactic for starving tumors — ScienceDaily

A tumor’s goal is simple: to grow, grow, grow, by making more cancer cells. But that often means growing so fast that the oxygen supply gets scarce, at which point cells within the tumor start to suffocate. Without oxygen, these ever-dividing cells struggle to make enough aspartate, a crucial ingredient in many cellular processes. That’s the scenario worked out by the research group of Kivanç Birsoy, head of the Laboratory of Metabolic Regulation and Genetics at The Rockefeller University. It…

The photoelectric effect in stereo — ScienceDaily

When a photon hits a material, it can eject an electron from it provided it has enough energy. Albert Einstein found the theoretical explanation of this phenomenon, which is known as the photoelectric effect, in Bern during his “year of wonders” 1905. That explanation was a crucial contribution to the development of quantum mechanics, which was under way at the time, and it earned him the Nobel Prize in Physics in 1921. An international team of physicists led by Ursula…

Chemists teach an enzyme a new trick, with potential for building new molecules — ScienceDaily

Princeton chemists have found a way to make a naturally occurring enzyme take on a new, artificial role, which has significant implications for modern chemistry, including pharmaceutical production. Their work appears in the journal Nature Chemistry. “We have found a completely new way to get enzymes to do a non-natural reaction,” said Todd Hyster, an assistant professor of chemistry. “A traditional perspective says that enzymes will only do one thing. This paper shows that this may not be true for…

Overuse of agricultural chemicals on China’s small farms harms health and environment — ScienceDaily

Overuse of agricultural chemicals on China’s small farms harms health and environment: new study The size of farms in China is a key contributor to the overuse of agricultural chemicals, and as a result they may be too small to be environmentally sustainable, a new study has found. The research — conducted by a team from the Universities of Melbourne, Zhejiang, Fudan, Wuhan and Stanford — is published today in the Proceedings of the National Academy of Sciences. The study…

New technique speeds analysis of crop traits

Nebraska researchers have devised a more efficient and accurate way to scan the structural properties of plants. Credit: Yufeng Ge | Suresh Thapa | Scott Schrage A potted nine-leaf corn plant sits on a Frisbee-sized plate. The tandem begins rotating like the centerpiece atop a giant music box, three degrees per second, and after two minutes the plant has pirouetted to its original position. Another minute passes, and on a nearby screen appears a digital 3-D image in the palette…

Novel method to grow elastic diamonds — ScienceDaily

Diamonds is the strongest naturally occurring material on Earth. It is also renowned for its incomparable properties, such as high stiffness, exceptional thermal conductivity, high chemical resistance, and high optical transparency. Although these remarkable properties of diamond make it highly desirable for many scientific and technological applications, progress has been slow due to its brittleness. A recent study, affiliated with UNIST has unveiled that brittle diamonds can be bent and stretched elastically when made into ultrafine needles. This breakthrough has…

Drones will help investigators tackle chemical, biological and nuclear attacks

Credit: Shutterstock Researchers are making use of unarmed vehicles and robots to gather information and samples from crime or disaster scenes. Their initiative will help save lives. Risks that involve chemical, biological, radiological, nuclear and explosive (CBRNe) materials are among major safety concerns. Accidental or targeted, events caused by such agents could be hazardous to humans. They could also hinder and endanger any subsequent forensic investigations. To address the challenges involved in examining such incidents, researchers from the EU-funded…

STEM Cubs sees record-setting attendance

The 120+ students marked the highest attendance at a STEM Cubs event to date with more than 200 applications to participate. A total of 16 volunteers from Engineering and Education helped the event run smoothly. Photo by Trevor Liptak. Last weekend, Lafferre Hall played host to 120+ students for the third edition of STEM Cubs, the free engineering day camp that illustrates the importance of exploratory and experiential learning in science, technology, engineering and math for students from kindergarten through…
