A urine sample could be used to diagnose a complex and serious pregnancy disorder

A urine sample could be used to diagnose a complex and serious pregnancy disorder

A team of scientists from the Federal State Budget Institution "Research Center for Obstetrics, Gynecology and Perinatology", Moscow Institute of Physics and Technology, the Emanuel Institute for Biochemical Physics, and the Talrose Institute for Energy Problems of Chemical Physics have developed an approach for a method of non-invasive testing for pregnant women with a serious and complex condition called preeclampsia. In simpler terms, the scientists have found potential biomarkers in the urine of pregnant women.

PPPL physicist conducts experiments indicating efficiency of fusion start-up technique

PPPL physicist conducts experiments indicating efficiency of fusion start-up technique

Physicist Fatima Ebrahimi at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University has for the first time performed computer simulations indicating the efficiency of a start-up technique for doughnut-shaped fusion machines known as tokamaks. The simulations show that the technique, known as coaxial helicity injection (CHI), could also benefit tokamaks that use superconducting magnets. The research was published in March 2016, in Nuclear Fusion, and was supported by the DOE's Office of Science.

Deep, old water explains why Antarctic Ocean hasn't warmed

Deep, old water explains why Antarctic Ocean hasn't warmed

The waters surrounding Antarctica may be one of the last places to experience human-driven climate change. New research from the University of Washington and the Massachusetts Institute of Technology finds that ocean currents explain why the seawater has stayed at roughly the same temperature while most of the rest of the planet has warmed.

Spin glass physics with trapped ions

Spin glass physics with trapped ions

One of the most striking discoveries of quantum information theory is the existence of problems that can be solved in a more efficient way with quantum resources than with any known classical algorithm.

Number-partitioning, which refers to the simple task of dividing a set of numbers into two groups of equal sums is, in fact, a very difficult problem to solve with classical computers.

Underwater grass beds have ability to protect and maintain their own health

Underwater grass beds have ability to protect and maintain their own health

CAMBRIDGE, MD (May 26, 2016)--An expansive bed of underwater grass at the mouth of the Susquehanna River has proven it is able to "take a licking and keep on ticking." A recent study has found that the submersed aquatic vegetation (SAV) bed at Susquehanna Flats, which only recently made a comeback in the Chesapeake Bay, was not only able to survive a barrage of rough storms and flooding, but it has proven a natural ability to protect and maintain itself.

Arctic Ocean methane does not reach the atmosphere

Arctic Ocean methane does not reach the atmosphere

250 methane flares release the climate gas methane from the seabed and into the Arctic Ocean. During the summer months this leads to an increased methane concentration in the ocean. But surprisingly, very little of the climate gas rising up through the sea reaches the atmosphere.

"Our results are exciting and controversial", says senior scientist Cathrine Lund Myhre from NILU - Norwegian Institute for Air Research, who is cooperating with CAGE through MOCA project.

The results were published in Geophysical Research Letters.

Expert urges voluntary family planning to mitigate climate change

Expert urges voluntary family planning to mitigate climate change

With climate change already close to an irreversible tipping point, urgent action is needed to reduce not only our mean (carbon) footprints but also the "number of feet" - that is, the growing population either already creating large footprints or aspiring to do so, argues a leading physician and environmentalist in The BMJ today.

Yet John Guillebaud, Emeritus Professor of Family Planning and Reproductive Health at University College London, says most climate change discussions focus only on technology and consumption.

New survey shows that retirement includes work for many older Americans

May 10, 2016, Chicago--Departing the workforce entirely and entering retirement at age 65 is no longer a reality for many older people in the United States, according to a recent survey by The Associated Press-NORC Center for Public Affairs Research. The study finds that there are large numbers of older Americans who are currently, or who expect to be, working longer. However, this doesn't necessarily mean that they are continuing with the same employment circumstances indefinitely.

At the top of their game

Being at the top of the food chain is no guarantee of a species survival. Not only are many of these so-called apex predators susceptible to human impacts, they also are slow to recover from them, which makes these animals vulnerable despite their high-ranking ecosystem status.

Schrödinger's cat is alive and dead in 2 places at once

Through new experiments involving the famous Schrödinger cat state paradox, researchers have shown that a "quantum cat" can be both alive and dead, and in two places at once. The results, which involve inducing a large number of photons to have matching states (or to become entangled), show the ability to manipulate complex quantum states, with applications for computation and long-distance communication. They also represent perhaps the first time scientists have been able to achieve such quantum coherence at a macroscopic scale.
