22:18 WhatReallyHappened.com Are some black holes wormholes in disguise? Gamma-ray blasts may shed clues.

Unusual flashes of gamma rays could reveal that what appear to be giant black holes are actually huge wormholes, a new study finds. Wormholes are tunnels in space-time that can theoretically allow travel anywhere in space and time, or even into another universe. Einstein's theory of general relativity suggests wormholes are possible, although whether they really exist is another matter. In many ways, wormholes resemble black holes. Both kinds of objects are extremely dense and possess extraordinarily strong gravitational pulls for bodies their size. The main difference is that no object can theoretically come back out after crossing a black hole's event horizon — the threshold where the speed needed to escape the black hole's gravitational pull exceeds the speed of light — whereas any body entering a wormhole could theoretically reverse course.

Unlike secondary batteries that need to be recharged, fuel cells are a type of eco-friendly power generation system that produce electricity directly from electrochemical reactions using hydrogen as fuel and oxygen as oxidant. There are various types of fuel cells, differing in operating temperatures and electrolyte materials. Solid oxide fuel cells (SOFCs), which use a ceramic electrolyte, are receiving increasing attention. Because they operate at high temperatures around 700 degrees Celsius, they offer the highest efficiency among fuel cell types, and can also be used to produce hydrogen by steam decomposition. For the commercialization of this technology, further improvement of cell performance is necessary, and novel high-temperature catalyst materials are highly anticipated.

The new calculation gives a more accurate prediction for the likelihood with which kaons decay into a pair of electrically charged pions vs. a pair of neutral pions.

03:45 ScienceDaily.com 'Floating' graphene on a bed of calcium atoms

Adding calcium to graphene creates an extremely-promising superconductor, but where does the calcium go? In a new study, a Monash-led team has for the first time confirmed what actually happens to those calcium atoms. Surprising everyone, the calcium goes underneath both the upper graphene sheet and a lower 'buffer' sheet, 'floating' the graphene on a bed of calcium atoms.

An international collaboration of theoretical physicists—including scientists from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory (BNL) and the RIKEN-BNL Research Center (RBRC)—has published a new calculation relevant to the search for an explanation of the predominance of matter over antimatter in our universe. The collaboration, known as RBC-UKQCD, also includes scientists from CERN (the European particle physics laboratory), Columbia University, the University of Connecticut, the University of Edinburgh, the Massachusetts Institute of Technology, the University of Regensburg, and the University of Southampton. They describe their result in a paper to be published in the journal Physical Review D and has been highlighted as an "editor's suggestion."

16:42 Phys.org Space communication: developing a one photon-per-bit receiver using near-noiseless phase-sensitive amplification

During space-communication researchers require high-space intersatellite data transfer connectivity for deep-space missions while monitoring Earth. The technology is fundamentally influenced by available transmission power and the aperture size of receiver sensitivity. The transition from radio-frequency links to optical links is now under consideration due to its ability to significantly reduce the channel loss caused by diffraction during communication. In a widely used approach, researchers can develop power-efficient formats along with nanowire-based photon-counting receivers cooled to a few Kelvins to function at speeds below 1-Gigabytes per second (Gb/s). In order to achieve data transfer at data rates of multi-GB/s (as expected for future space applications) the systems will have to rely on pre-amplified receivers together with advanced signal generation and processing techniques, including fibre communications.
