Physicists have succeeded in teleporting the quantum state of a photon to a crystal over 25 kilometers of optical fiber. The experiment constitutes a first, and pulverizes the previous record of six kilometers achieved 10 years ago by the same team.
The California State Teachers' Retirement System says it plans to increase its investments in clean energy and technology to $3.7 billion, from $1.4 billion, over the next five years.
Chronic stress can lead to behavioral problems. A team of researchers has discovered an important synaptic mechanism: the activation of a cleaving enzyme, leading to these problems.
The government said Friday it will rewrite sweeping new food safety rules after farmers complained that earlier proposals could hurt business. New proposals by the FDA would make it easier for farmers to meet water quality standards and allow farmers to harvest crops sooner after using raw manure as fertilizer.
A dazzling show of fire and color can make science come alive for young students, but it can also inflict serious and painful injuries, as flash fires in Nevada and Colorado showed this month.
Researchers who found that packing strips of cured pork in the nose of a child who suffers from uncontrollable, life-threatening nosebleeds can stop the hemorrhaging won an Ig Nobel prize last night. Other winners included a team of researchers who wondered if owning a cat was bad for your mental health and Japanese scientists who tested whether banana peels are really slippery.
A multidisciplinary team of scientists are using some of the most advanced X-ray micro Computed Tomography scanners to learn how to design plant roots so they can interact better with soil and capture water and nutrients more efficiently. This non-invasive technology will help them unearth some of the answers to one of the biggest challenges facing the world today— global food security.
It is a cruel world out there, particularly for young animals born into social groups where infanticide occurs. This dark side of evolution is revealed when adults– often males– kill offspring to promote their own genes being passed on, by reducing competition for resources or making females become sexually receptive more quickly.
Most people would describe confidence as an emotion or a feeling. In contrast, scientists have found that confidence is actually a measureable quantity, and not reserved just for humans. A team has identified a brain region in rats whose function is required for the animals to express confidence in their decisions.
“Here’s some of the stories trending This Week at NASA!” Returning human spaceflight to America
Considered to be at the forefront of microscopy technology in agriculture, the Donald Danforth Plant Science Center in St. Louis, Missouri supports education, industry and innovation under one roof.
Eating too much meat often makes the headlines, whether the risk of doing so is equated to smoking or cited as the cause of rising diabetes rates. Though some of these articles have already been labeled as sensational journalism, a new study has shown that people who eat more protein— whether from plant or animal sources— tend to have a lower risk of hypertension, also known as high blood pressure.
Corrosion resistance and high strength put stainless steel high on the list of essential materials for satellite and rocket designers. Now, ESA plans to investigate an alternative, environmental-friendly method of readying this important metal.
Research shows that homicide rates in many countries are falling; leading experts from around the world believe that global rates of homicide and other interpersonal violence— such as child abuse and domestic violence— could be reduced by as much as 50 percent in just 30 years if governments implement the right policies.
