In 2013, James E. Rothman, Randy W. Schekman, and Thomas C. Südhof won the Nobel Prize in Physiology or Medicine for their discoveries of molecular machineries for vesicle trafficking, a major transport system in cells for maintaining cellular processes. Show More Summary
Researchers have found that green roofs with high vegetation density are 60% more efficient than non-green roofs.
Fewer industrial firms would violate environmental legislation and a higher number would adopt cleaner technologies if environmental authorities would focus their monitoring efforts on companies with the most environmentally damaging technology. At a societal level, such a strategy would mean less pollution at the same or a lower cost of monitoring, according to new research.
The EU wants to further improve the authorization process for pesticides. The different national procedures for this are supposed to be further harmonized. Researchers have now developed a software for estimating the transfer of pesticides into surface water initially in Germany.
Of 85 UCLA undergraduate students, only one correctly recalled the Apple logo when asked to draw it on a blank sheet of paper, psychologists found. Fewer than half correctly identified the logo when shown several options.
Just as crocus and daffodil blossoms signal the start of a warmer season on land, a similar 'greening' event --a massive bloom of microscopic plants, or phytoplankton -- unfolds each spring in the North Atlantic Ocean from Bermuda to the Arctic.
A new study found that more than one-third of elite, Division I college athletes may have low levels of vitamin D, which is critical in helping the body to absorb calcium needed to maintain bone mass, and to minimize musculoskeletal pain and injury risk.
Patients with Clostridium difficile infection (CDI) are twice as likely to be readmitted to the hospital as patients without the deadly diarrheal infection, according to a new study.
Lettuce, one of the indispensable vegetables in the Mediterranean diet, is a food that greatly benefits health, mainly because it is rich in antioxidants. But not all lettuce varieties have the same antioxidant effect. The color of the leaves of these vegetables determines the speed at which their compounds act. Show More Summary
Brown fat tissue, the body’s “good fat,” communicates with the brain through sensory nerves, possibly sharing information that is important for fighting human obesity, such as how much fat we have and how much fat we’ve lost, according to researchers.
The official global target of a two degree Celsius temperature rise is 'utterly inadequate' for protecting those at most risk from climate change, says an expert. The commentary presents a rare inside-view of a discussion at the Lima Conference of the Parties on the likely consequences of accepting an average global warming target of 2 degrees Celsius versus 1.5 degrees Celsius.
Scientists report on the detection of particle entanglement in a beam of squeezed light. Researchers were able to observe effects of entanglement monogamy, where particles can be strongly entangled only if they have few entanglement partners.
So-called 'triple-negative breast cancers' are two distinct diseases that likely originate from different cell types, researchers have found. They have also found a gene that drives the aggressive disease, and hope to find a way to 'switch it off'.
A new study identifies common causes of hospital readmissions following total hip and knee arthoplasty procedures among patients involved in a Bundled Payment Care Initiative. By finding these common causes, researchers believe quality can be increased and hospital costs decreased.
Using a simulation model, researchers have shown that the implementation of Fracture Liaison Services could considerably reduce the human and healthcare costs associated with osteoporotic fractures.
A new study shows that genes crucial for vision were multiplied in the early stages of vertebrate evolution and acquired distinct functions leading to the sophisticated mechanisms of vertebrate eyes.
The first fully implantable micropacemaker designed for use in a fetus with complete heart block has been designed by researchers. The investigators anticipate the first human use of the device in the near future.
Honey bees use different sets of genes, regulated by two distinct mechanisms, to fight off viruses, bacteria and gut parasites, according to researchers. The findings may help scientists develop honey bee treatments that are tailored to specific types of infections.
An obstacle course was used by researchers to evaluate a wearable collision warning device they developed for patients with peripheral vision loss. They found the device may help patients with a wide range of vision loss avoid collisions with high-level obstacles.
Within the next five to ten years, around 100 billion different devices will be online. A large part of the communication takes place solely between machines, and to ensure that they can communicate, the European Commission has supported...Show More Summary
