Plants produce a range of chemicals known as volatile organic compounds that influence their interactions with the world around them. In a new study, researchers at the University of Illinois Urbana-Champaign investigated how the type and amount of these VOCs change based on different features of tomato plants. The smell of cut grass is one of the defining fragrances of summer. Smells like that are one of the ways plants signal their injury. Because they cannot run away from danger, plants have evolved to communicate with each other using chemical signals. They use VOCs for a ...

ITHACA, N.Y. – Cornell University engineers have created a new lithium battery that can charge in under five minutes – faster than any such battery on the market – while maintaining stable performance over extended cycles of charging and discharging. The breakthrough could alleviate “range anxiety” among drivers who worry electric vehicles cannot travel long distances without a time-consuming recharge. “Range anxiety is a greater barrier to electrification in transportation than any of the other barriers, like cost and capability of batteries, and we have identified a pathway to eliminate it using rational electrode designs,” said Lynden ...

R. Graham Cooks, the Henry B. Hass Distinguished Professor of Chemistry, and his postdoctoral researcher Lingqi Qiu have experimental evidence that the key step in protein formation can occur in droplets of pure water, and have recently published these findings in the Proceedings of the National Academy of Sciences (PNAS). In this key step, amino acids are dehydrated (they lose water) even though they are in a water solution, a paradox that is resolved by the fact that these droplet surfaces are unusually dry and highly ...

Like humans, mice live in complex social groups, fight over territory and mates, and learn when it is safer to avoid certain opponents. After losing even a brief fight, the defeated animals will flee from the mice that hurt them for weeks afterward, a new study shows. Led by researchers at NYU Grossman School of Medicine, the study reveals that such “retreating behavior” is influenced by a distinct area on the underside of the hypothalamus, a part of the brain that controls hunger, sleep, and levels of many hormones. The team had previously found that this special region, called the anterior ventrolateral part of the ventromedial hypothalamus (aVMHvl), ...

Bacterial infections cause millions of deaths each year, with the global threat made worse by the increasing resistance of the microbes to antibiotic treatments. This is due in part to the ability of bacteria to switch genes on and off as they sense environmental changes, including the presence of drugs. Such switching is accomplished through transcription, which converts the DNA in genes into its chemical cousin in mRNA, which guides the building of proteins that make up the microbe’s structure. For this ...

Cryptocurrency is usually “mined” through the blockchain by asking a computer to perform a complicated mathematical problem in exchange for tokens of cryptocurrency. But in research appearing in the journal Chem on January 24, a team of chemists have repurposed this process, asking computers to instead generate the largest network ever created of chemical reactions which may have given rise to prebiotic molecules on early Earth. This work indicates that at least some primitive forms of metabolism might have emerged without the involvement of ...

About The Study: In this study of 4,360 patients with traumatic brain injury (TBI), functional limitations six months after injury were common after sports-related TBI, even mild sports-related TBI. Persisting impairment was evident in the sports-related TBI group despite better recovery compared with non–sports-related TBI on measures of mental health and post-concussion symptoms. These findings caution against taking an overoptimistic view of outcomes after sports-related TBI, even if the initial injury appears mild. Authors: Lindsay Wilson, ...

Researchers at the Universities of Basel and Zurich have discovered the genetic material of the pathogen Treponema pallidum in the bones of people who died in Brazil 2,000 years ago. This is the oldest verified discovery of this pathogen thus far, and it proves that humans were suffering from diseases akin to syphilis – known as treponematoses – long before Columbus’s discovery of America. The new findings, published in the scientific journal Nature, call into question previous theories concerning the spread of syphilis ...

Reactive oxygen species (ROS) are highly reactive molecules containing oxygen. These compounds, which are normal byproducts of biological processes in all living organisms such as aerobic respiration as well as photosynthesis, are highly toxic. In most cases, ROS damage cellular machinery and can trigger a harmful stress response if their levels are not kept in tight check; this is why antioxidants are an important part of our diet.   However, over the past few decades, scientists have discovered that ROS are often intentionally ...
