X-rays detected from the dark side of Venus
Phys.org - latest science and technology news stories - Hace 7 horas
Venus and Mercury have been observed transiting the Sun many times over the past few centuries. When these planets are seen passing between the Sun and the Earth, opportunities exist for some great viewing, not to mention serious research. And whereas Mercury makes transits with greater frequency (three times since 2000), a transit of Venus is something of a rare treat.

Animals feeding at sea inherit a chemical record reflecting the area where they fed, which can help track their movements, according to a new study by scientists from the University of Southampton.
History shows experiments to be just as key as theory in gravity physics
Phys.org - latest science and technology news stories - Hace 7 horas
In the 1950s and earlier, the gravity theory of Einstein's general relativity was largely a theoretical science. In a new paper published in EPJ H, Jim Peebles, a physicist and theoretical cosmologist who is currently the Albert Einstein Professor Emeritus of Science at Princeton University, New Jersey, USA, shares a historical account of how the experimental study of gravity evolved.
New method to make permanent magnets more stable over time
Phys.org - latest science and technology news stories - Hace 7 horas
For physicists, loss of magnetisation in permanent magnets can be a real concern. In response, the Japanese company Sumitomo created the strongest available magnet—one offering ten times more magnetic energy than previous versions—in 1983. These magnets are a combination of materials including rare-earth metal and so-called transition metals, and are accordingly referred to as RE-TM-B magnets. A Russian team has now been pushing the boundaries of magnet design, as published in a recent study in EPJ Plus.

Vitamins A and C help erase cell memory
Phys.org - latest science and technology news stories - Hace 8 horas
Vitamins A and C aren't just good for your health, they affect your DNA too. Researchers at the Babraham Institute and their international collaborators have discovered how vitamins A and C act to modify the epigenetic 'memory' held by cells; insight which is significant for regenerative medicine and our ability to reprogramme cells from one identity to another. The research is published today in Proceedings of the National Academy of Science (PNAS).
Quantum-dot solar windows evolve with 'doctor-blade' spreading
Phys.org - latest science and technology news stories - Hace 8 horas
In a paper this week for the journal Nature Energy, a Los Alamos National Laboratory research team demonstrates an important step in taking quantum dot, solar-powered windows from the laboratory to the construction site by proving that the technology can be scaled up from palm-sized demonstration models to windows large enough to put in and power a building.
'Time machine' study warns of long-term dangers of ocean acidification
Phys.org - latest science and technology news stories - Hace 8 horas
New research into the effects of ocean acidification suggests that, while marine organisms may be able to cope with the effects of climate change in the short term, the biological cost of doing so may be too high to guarantee long-term survival.

New dwarf planet found in our solar system
Phys.org - latest science and technology news stories - Hace 8 horas
(Phys.org)—A team of space scientists at the University of Michigan has discovered a dwarf planet that is approximately half the size of Pluto and twice as far from the sun. The sighting was reported by NPR, which interviewed team lead physicist David Gerdes. He told them credit goes to a group of students who were challenged to find some new objects to add to the ongoing construction of a galaxy map. Their efforts led to software that can be used to analyze imagery from the Dark Energy Camera (the camera used as part of the ongoing Dark Energy Survey). It looks for objects that are... más »
