• New bioimaging technique is fast and economical

  18-08-2017 23:52
  A new approach to optical imaging makes it possible to quickly and economically monitor multiple molecular interactions in a large area of living tissue—such as an organ or a small animal; technology that could have applications in medical diagnosis, guided surgery, or pre-clinical drug testing. The method, which is detailed in Nature Photonics, is capable of simultaneously tracking 16 colors of spatially linked information over an area spanning several centimeters, and can capture interac

• Astrophysicist predicts detached, eclipsing white dwarfs to merge into exotic star

  18-08-2017 23:51
  A University of Oklahoma astrophysicist, Mukremin Kilic, and his team have discovered two detached, eclipsing double white dwarf binaries with orbital periods of 40 and 46 minutes, respectively. White dwarfs are the remnants of Sun-like stars, many of which are found in pairs, or binaries. However, only a handful of white dwarf binaries are known with orbital periods less than one hour in the Milky Way—a galaxy made up of two hundred billion stars—and most have been discovered by Kil

• A quick and easy way to shut down instabilities in fusion devices

  18-08-2017 20:28
  Scientists have discovered a remarkably simple way to suppress a common instability that can halt fusion reactions and damage the walls of reactors built to create a "star in a jar." The findings, published in June in the journal Physical Review Letters, stem from experiments performed on the National Spherical Torus Experiment-Upgrade (NSTX-U), at the Department of Energy's Princeton Plasma Physics Laboratory (PPPL).

• Engineers deliver new key components to help power a fusion energy experiment

  18-08-2017 18:20
  Fusion power, which lights the sun and stars, requires temperatures of millions of degrees to fuse the particles inside plasma, a soup of charged gas that fuels fusion reactions. Here on Earth, scientists developing fusion as a safe, clean and abundant source of energy must produce temperatures hotter than the core of the sun in doughnut-shaped facilities called tokamaks. Much of the power needed to reach these temperatures comes from high-energy beams that physicists pump into the plasma throug

• Drug resistance in an intestinal parasite of piglets confirmed for the first time

  The parasite Cystoisospora suis causes diarrhea in pigs, especially in newborn piglets, and is capable of quickly spreading across farms. For this reason, pig farmers in Europe preventively use toltrazuril to control parasite development. In contrast to congeneric parasites in chicken, no resistance to this pharmaceutical compound was described in pig parasites until recently. In an article in Parasites & Vectors, researchers of the University of Veterinary Medicine, Vienna, have now for the

• Want more women in top positions? Provide them with more flexibility at work

  The recent BBC report on the pay of its top earners laid bare the disparities between men and women's earnings. But it should come as no surprise. The gender pay gap has been stubbornly stagnant over the past decade. According to the EU (which calculates the gap based on hourly pay differences between men and women), men earn around 20 percent more. And the UK's official statistics group, which calculates the pay gap of full-time earnings, men earn an average of about 10 percent more than women.

  In the evolution of tetrapods, the position of the hindlimb has diversified along with the vertebral formula, which is the number of small bones forming the vertebra. Tetrapods, as the name implies, are species that have four feet. However, this group also includes many other animals without four or any feet, such as snakes and birds. This is because tetrapods include all the organisms, living and extinct, that descended from the last common ancestor of amphibians, reptiles and mammals, even if
