Reproduction can be risky. In the case of katydids, some hunting bats eavesdrop on male mating calls to locate the insects, but little is known about the risk to mates as they move toward each other. A recent study by scientists at the Smithsonian Tropical Research Institute (STRI) and collaborating institutions explores the hunting behavior of a Neotropical bat, asking whether prey movement adds to the risk that they will be eaten.
Like people, neurons need to talk to one another. But instead of turning thoughts into words, these cells convert electrical signals into chemical ones. For nearly 30 years, biochemist Edwin Chapman has studied how one protein triggers this crucial conversion.
Two-dimensional (2D) materials, which consist of a single layer of atoms, have attracted a lot of attention since the isolation of graphene in 2004. They have unique electrical, optical, and mechanical properties, like high conductivity, flexibility and strength, which makes them promising materials for such things as lasers, photovoltaics, sensors and medical applications.
Honey bee colonies from across the UK are increasingly suffering from a viral disease, a new study has shown.
Publishing their findings in the journal Nature Communications, the team led by Professor Giles Budge of Newcastle University, UK, found that the number of honey bee colonies affected with chronic bee paralysis rose exponentially between 2007 and 2017.
Inland waters such as rivers, lakes and reservoirs play an important role in the global carbon cycle. Calculations that scale up the carbon dioxide emissions from land and water surface areas do not take account of inland waters that dry out intermittently. This means that the actual emissions from inland waters have been significantly underestimated - as shown by the results of a recent international research project led by scientists at the Helmholtz Centre for Environmental Research (UFZ) in Magdeburg and the Catalan Institute for Water Research (ICRA).
At the Paul Scherrer Institute PSI, researchers have gained insights into a promising material for organic light-emitting diodes (OLEDs). The substance enables high light yields and would be inexpensive to produce on a large scale - that means it is practically made for use in large-area room lighting. Researchers have been searching for such materials for a long time. The newly generated understanding will facilitate the rapid and cost-efficient development of new lighting appliances in the future. The study appears today in the journal Nature Communications.
CU Boulder researchers have developed a method that could enable scientists to accurately forecast ocean acidity up to five years in advance. This would enable fisheries and communities that depend on seafood negatively affected by ocean acidification to adapt to changing conditions in real time, improving economic and food security in the next few decades.
A technique for studying individual circuits in the brains of mice has been hampered because the light needed to stimulate neural activity briefly overwhelms the electrodes "listening" for the response. Now, improved shielding within the neural probe enables those lost signals to be captured.
Overview
Bronx, NY (May 1, 2020) People with cancer who develop COVID-19 are much more likely to die from the disease than those without cancer, according to physician-researchers at Montefiore Health System and Albert Einstein College of Medicine.
HOUSTON -- (April 30, 2020) -- Rice University researchers have discovered a hidden symmetry in the chemical kinetic equations scientists have long used to model and study many of the chemical processes essential for life.
Scientists have been able to observe the universe and determine that about 80% of the its mass appears to be "dark matter," which exerts a gravitational pull but does not interact with light, and thus can't be seen with telescopes. Our current understanding of cosmology and nuclear physics suggests that dark matter could be made of axions, hypothetical particles with unusual symmetry properties.
A plant extract combination of fruits, leaves, and roots may help to relieve hangover symptoms, reveals research published online in BMJ Nutrition Prevention & Health.
And received wisdom that it's the dehydrating effects of alcohol and the associated loss of electrolytes--electrically charged minerals in the body that help balance water content and acid levels--which are largely responsible for some of the most common hangover symptoms, may be wrong, the findings indicate.
A new study shows the cost of cancer care for Syrian refugees in host nations for the first time, as researchers urge resources to be provided in the wake of the COVID-19 pandemic.
The study published today in the Lancet Oncology, led by researchers at King's College London and a collaboration between the cancer and palliative care working group within UKRI Global Challenge Research Fund R4HC-MENA programme (r4hc-mena.org), shows the increasing cost of cancer care for refugees on host nations such as Turkey, Lebanon and Jordan.
A discovery that long eluded physicists has been detected in a laboratory at Princeton. A team of physicists detected superconducting currents -- the flow of electrons without wasting energy -- along the exterior edge of a superconducting material. The finding was published in the May 1 issue of the journal Science.
