Gamma-Ray Burst Captured in Unprecedented Detail
College Park MD (SPX) Jul 26, 2017 -
Gamma-ray bursts are among the most energetic and explosive events in the universe. They are also short-lived, lasting from a few milliseconds to about a minute. This has made it tough for astronomers to observe a gamma-ray burst in detail.
Using a wide array of ground- and space-based telescope observations, an international team led by University of Maryland astronomers constructed one o ...

Using powerful Dark Energy Camera, scientists reach the cosmic dawn
Tempe AZ (SPX) Jul 27, 2017 -
Arizona State University astronomers Sangeeta Malhotra and James Rhoads, working with international teams in Chile and China, have discovered 23 young galaxies, seen as they were 800 million years after the Big Bang. The results from this sample have been recently published in the Astrophysical Journal.
Long ago, about 300,000 years after the beginning of the universe (the Big Bang), the u ...

Large-mouthed fish dominated the seas following mass extinction
Washington (UPI) Jul 26, 2017 -
A team of American and Swiss paleontologists have identified one of the earliest large predatory fish species from the Triassic period. Scientists suggest the large-mouthed fish dominated the seas in the aftermath of the Permian-Triassic extinction event.
The extinction event separating the Permian and Triassic periods occurred 252 million years ago. It was the most devastating extincti ...

Designing soft robots: Ethics-based guidelines for human-robot interactions
New Rochelle NY (SPX) Jul 27, 2017 -
Soft-bodied robots offer the possibility for social engagement, and novel tactile human-robot interactions that require careful consideration of the potential for misplaced emotional attachments and personally and socially destructive behavior by users.
The ethical challenges related to human-robot interactions and how these should contribute to soft robotics design in the context of socia ...

The role of the entropy in a quantum system
Trieste, Italy (SPX) Jul 27, 2017 -
A deep understanding of the irreversibility of the arrow of time cannot ignore the quantum nature of the world that surrounds us. The is the key result of the work carried out by Vincenzo Alba and Pasquale Calabrese of the International School for Advanced Studies (SISSA) of Trieste, recently published in the journal Proceedings of the National Academy of Sciences (PNAS).
According to one ...

Natural molecule to boost the performance of electrodes for rechargeable batteries
Karlsruher, Germany (SPX) Jul 27, 2017 -
Chlorophyll, blood, and vitamin B12 are all based on the porphyrin molecule. But porphyrin can also be used as an electrode material where it speeds up the charging process of rechargeable batteries. In the "Angewandte Chemie International Edition" journal, researchers from KIT now present the new material system that could mark the beginning of an era of high-performance energy storage and supe ...

Pulses of electrons manipulate nanomagnets and store information
Washington DC (SPX) Jul 24, 2017 -
Magnets and magnetic phenomena underpin the vast majority of modern data storage, and the measurement scales for research focused on magnetic behaviors continue to shrink with the rest of digital technology. Skyrmions, for example, are a kind of nanomagnet, comprised of a spin-correlated ensemble of electrons acting as a topological magnet on certain microscopic surfaces. The precise properties, ...

Large single-crystal graphene is possible
Seoul, South Korea (SPX) Jul 27, 2017 -
Boasting the conductivity, strength and flexibility we wished for, graphene was proposed as one of the most likely substitutes for silicon and other materials. Its launch into the market however is still slow. What is curbing graphene from industrial applications? One factor is that top quality single-crystal graphene produced so far is just a couple of millimeters or maximum centimeters in size ...

Tehran (AFP) July 27, 2017 -
Iran on Thursday "successfully" tested a satellite-launch rocket, days after warning Washington of a response to new US sanctions over the Islamic republic's ballistic missile programme, state television said.
It said the launch vehicle, named Simorgh after a bird in Iranian mythology, was capable of propelling a satellite weighing 250 kilograms (550 pounds) to an altitude of 500 kilometres ...

Perched on the edge of a 39-million-year-old crater is a white circular hut. It sticks out on the rocky, lichen-dotted landscape of Devon Island in Nunavut, Canada.
Known as "the Hab," this 26-foot diameter structure is home to six scientists and researchers who just moved in for a 12-week mission to simulate life on Mars.
The Arctic has long been a frontier for exploration, and ...

Using new observations from ESO's VLT Survey Telescope, astronomers have discovered three different populations of young stars within the Orion Nebula Cluster. This unexpected discovery adds very valuable new insights for the understanding of how such clusters form. It suggests that star formation might proceed in bursts, where each burst occurs on a much faster time-scale than previously though ...

In a first-of-its-kind analysis, Northwestern University astrophysicists have discovered that, contrary to previously standard lore, up to half of the matter in our Milky Way galaxy may come from distant galaxies. As a result, each one of us may be made in part from extragalactic matter.
Using supercomputer simulations, the research team found a major and unexpected new mode for how galaxi ...

Things look different on the Moon. Literally. Because the Moon isn't big enough to hold a significant atmosphere, there is no air and there are no particles in the air to reflect and scatter sunlight.
On Earth, shadows in otherwise bright environments are dimly lit with indirect light from these tiny reflections. That lighting provides enough detail that we get an idea of shapes, holes and ...
