WEST LAFAYETTE, Ind. -- Scientists have long suspected that a quantum phenomenon might play a role in photosynthesis and other chemical reactions of nature, but don't know for sure because such a phenomenon is so difficult to identify.
Purdue University researchers have demonstrated a new way to measure the phenomenon of entanglement in chemical reactions - the ability of quantum particles to maintain a special correlation with each other over a large distance.
Inspired by the intricate system of water circulating in a tree, a team of researchers led by Princeton University, have figured out how to use a thin slice of wood as a membrane through which water vapor can evaporate, leaving behind salt or other contaminants.
Soon after Tropical Storm Francisco developed in the Northwestern Pacific Ocean NASA's Terra satellite passed overhead.
NASA's Terra satellite used infrared light to gather temperature information from newly developed Tropical Storm Francisco. The strongest thunderstorms reach high into the atmosphere and have the coldest cloud top temperatures.
What The Study Did: This study (called a systematic review and meta-analysis) combined the results of 46 observational studies involving nearly 121,000 nonfrail adults (60 or older from 28 countries) and estimated the rate of new cases of frailty and prefrailty, which is a high risk of progressing to frailty.

A combination of heart cells derived from human stem cells could be the answer to developing a desperately-needed treatment for heart failure, according to new research part-funded by the British Heart Foundation (BHF) and published in Nature Biotechnology.
Researchers have found that, by transplanting an area of damaged tissue with a combination of both heart muscle cells and supportive cells taken from the outer layer of the heart wall, they may be able to help the organs recover from the damage caused by a heart attack.
As you enter a new environment such as visiting a classroom for the first time, your brain takes in information about your surroundings to help inform where you are and what direction you are facing. Knowing where the center of the room is located helps provide a reference point for processing space.
Today, the National Oceanic and Atmospheric Administration (NOAA) released the Status of U.S. Fisheries Annual Report to Congress, which details the status of 479 federally-managed stocks or stock complexes in the U.S. to identify which stocks are subject to overfishing, are overfished, or are rebuilt to sustainable levels.
Wolves are charismatic, conspicuous, and easy to single out as the top predator affecting populations of elk, deer, and other prey animals. However, a new study has found that the secretive cougar is actually the main predator influencing the movement of elk across the winter range of northern Yellowstone National Park.
Tropical Storm Flossie continues tracking in a westward direction through the Eastern Pacific Ocean and is expected to move into the Central Pacific Ocean later today, August 2.
NASA's Aqua satellite used infrared light to provide temperature information of clouds and sea surface. The strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures. Cloud top temperatures that cold indicate strong storms with the potential to generate heavy rainfall.
In the midst of an unprecedented Zika crisis in Brazil, there were a few flickers of hope: Some babies appeared to be normal at birth, free of devastating birth defects that affected other Brazilian children exposed to the virus in utero. But according to a study published online July 8, 2019, in Nature Medicine and an accompanying commentary co-written by a Children's National clinician-researcher, the reality for Zika-exposed infants is much more complicated.
People think of electric scooters, or e-scooters, as environmentally friendly ways to get around town. But a new study from North Carolina State University finds it's not that simple: shared e-scooters may be greener than most cars, but they can be less green than several other options.
The Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) in Gatersleben has been promoting the transition of gene banks into bio-digital resource centres - the aim is the preparation and collation of the phenotypic and genetic information for all stored accessions. As an important step for the further development of the Federal Ex situ Gene Bank, which is being hosted by the IPK in Gatersleben, researchers have been evaluating the historical data which has been accrued by the gene bank over the last 70 years.
Despite their large body size, gorillas are known to have a vegetarian diet consisting almost exclusively of leafy vegetation and fruit. Their teeth are large and high crested when compared to other great apes which is traditionally seen as an adaptation to them spending a large amount of time chewing tough fibrous plant material. In contrast, their teeth are not well adapted to eating hard objects, such as nuts encased in a woody shell, because the high crests on their molar teeth would be at risk of damage.
A KAIST team has designed a novel strategy for synthesizing single-crystalline graphene quantum dots, which emit stable blue light. The research team confirmed that a display made of their synthesized graphene quantum dots successfully emitted blue light with stable electric pressure, reportedly resolving the long-standing challenges of blue light emission in manufactured displays. The study, led by Professor O Ok Park in the Department of Chemical and Biological Engineering, was featured online in Nano Letters on July 5.
Carbon nanotubes able to take on the desired shapes thanks to a special chemical treatment, called crosslinking and, at the same time, able to function as substrata for the growth of nerve cells, finely tuning their growth and activity. The research just published in ACS Nano, the prestigious international scientific journal, is a new and important step towards the construction of neuronal regenerative-interfaces to repair spinal injuries.
