An important step towards a completely new experimental access to quantum physics has been made by researchers in Germany. The team of scientists has now shown how to manipulate the electric vacuum field and thus generate deviations from the ground state of empty space which can only be understood in the context of the quantum theory of light.
A new way to identify the state and fate of individual stem cells earlier than previously possible has now been developed by a team of scientists.
Research used anonymous Facebook data from almost 17 million social connections in 55 countries to determine that the role of weak and strong ties in job searches is important around the world, but the value of a single strong tie is even more important for job seekers in countries with pronounced income inequality.
For decades, scientists have theorized that the movement of Earth's tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven significantly by the additional force of heat drawn from the Earth's core. The new findings also challenge the theory that underwater mountain ranges known as mid-ocean ridges are passive boundaries between moving plates. The findings show the East Pacific Rise, the Earth's dominant mid-ocean ridge, is dynamic as heat is transferred.
Massive sea lion, fur seal hunting in the Patagonian coasts is altering Southern Atlantic Ocean ecosystems
Sea lion hunting by the Europeans at the Atlantic coasts of South America – it started in the 19th Century and continued up to the second half of the 20th century in Argentina and Uruguay – changed its nutrition guidelines of these pinnipeds as well as the structure of the coastal trophic network, according to new research.
The multiple sclerosis (MS) therapy alemtuzumab can trigger severe, unpredictable side effects. Scientists report on two patients for whom the infusion of alemtuzumab significantly worsened symptoms. The team also describes a treatment that successfully curbed the harmful side effects.
Researchers have devised a new way to protect personal electronic health records using a patient's own heartbeat.
Gestational diabetes raises the risk of postpartum depression in first-time mothers, researcher have concluded.
Glaciologists have uncovered large valleys in the ocean floor beneath some of the massive glaciers flowing into the Amundsen Sea in West Antarctica. Carved by earlier advances of ice during colder periods, the troughs enable warm, salty water to reach the undersides of glaciers, fueling their increasingly rapid retreat.
Modern genome sequencing methods used to measure the efficiency of synthesis of individual protein during cell division has found that the enzymes that make lipids and membranes were synthesized at much greater efficiency when a cell is ready to split.
A new study has focused on the effects of exercise and physical activity on postmenopausal breast cancer survivors taking AIs -- hormone-therapy drugs that stop the production of estrogen. The work concludes that a combination of resistance and aerobic exercise helps mitigate the side effects of AIs and improves health outcomes in breast cancer survivors, particularly their body composition.
Scientists are planning to send a deep-space probe to a metal asteroid, enabling them to see what is believed to be a planetary core. Psyche, an asteroid orbiting the sun between Mars and Jupiter, is made almost entirely of nickel-iron metal.
Earth's 2016 surface temperatures were the warmest since modern recordkeeping began in 1880, according to independent analyses by NASA and NOAA. This makes 2016 the third year in a row to set a new record for global average surface temperatures.
Antidepressants prescribed to pregnant women could increase the chance of having a baby with birth defects, new research indicates.
A protein-coding gene called Schlafen11 (SLFN11) may induce a broad-spectrum cellular response against infection by viruses including HIV-1, researchers have discovered.
Vitamin B-12 exists in two different, incompatible forms in the oceans. An organism thought to supply essential vitamin B-12 in the marine environment is actually churning out a knockoff version.
Mobile phone, computer and TV displays all use very expensive color filters and other components, which cannot be easily recycled. Scientists have designed a new screen, which is cheaper and ecological as it uses a hybrid material. This material's luminescent proteins can be used in backlighting systems and color filters made using a 3-D printing technique.
The world relies heavily on gasoline and other hydrocarbons to power its cars and trucks. In search of an alternative fuel type, some researchers are turning to the stuff of fireworks and explosives: metal powders. And now one team is reporting a method to produce a metal nanopowder fuel with high energy content that is stable in air and doesn't go boom until ignited.
Treatment for certain diabetes cases involves constant monitoring of blood-glucose levels and daily insulin shots. But scientists are now developing a painless 'smart' patch that monitors blood glucose and releases insulin when levels climb too high. The device has been tested on mice.
Most people who have tried durian either love it or hate it. The fruit's yellowish flesh is sweet and custard-like, but it comes with an overpowering stench of garbage. Scientists studying the unique fruit have now analyzed a set of 20 stinky and fruity chemical ingredients and found that a mere two compounds can re-create the overall smell.
