Alcohol itself can directly damage liver cells. Now researchers at University of California, San Diego School of Medicine report evidence that alcohol is also harmful to the liver for a second reason -- it allows gut bacteria to migrate to the liver, promoting alcohol-induced liver disease. The study, conducted in mice and in laboratory samples, is published February 10 in Cell Host & Microbe.

The growing popularity of battery-powered cars could help reduce greenhouse gas emissions, but they are not entirely Earth friendly. Problems can creep in when these batteries are disposed of. Scientists, in a new study in ACS' journal Chemistry of Materials, are reporting that compounds increasingly used in lithium-ion batteries are toxic to a type of soil-dwelling bacteria that plays an important environmental role.
The team of mining archaeologists was supervised by Prof. Dr Denis Morin of the University of Lorraine, connected with the UMR CNRS 5608 (UMR National Center for Scientific Research 5608) of Toulouse. The scientists employed a drone to locate above-ground installations connected to the mining. It is the first time that such complex mining infrastructure is studied.
Hiroshima, Japan -- Hiroshima University, the National Institute of Information and Communications Technology, and Panasonic Corporation announced the development of a terahertz (THz) transmitter capable of signal transmission at a per-channel data rate of over ten gigabits per second over multiple channels at around 300 GHz. The aggregate multi-channel data rate exceeds one hundred gigabits per second. The transmitter was implemented as a silicon CMOS integrated circuit, which would have a great advantage for commercialization and consumer use.
(Edmonton) An engineering research team at the University of Alberta has invented a new transistor that could revolutionize thin-film electronic devices.
Their findings, published in the prestigious science journal Nature Communications, could open the door to the development of flexible electronic devices with applications as wide-ranging as display technology to medical imaging and renewable energy production.
Washington, D.C., Feb. 9, 2016 - Researchers at the French National Centre for Scientific Research, CNRS, and the University of Lorraine have recently developed a design for a coiled-up acoustic metasurface which can achieve total acoustic absorption in very low-frequency ranges.
"The main advantage is the deep-subwavelength thickness of our absorber, which means that we can deal with very low-frequencies - meaning very large wavelengths - with extremely reduced size structure," said Badreddine Assouar, a principal research scientist at CNRS in Nancy, France.
Research results recently presented in the distinguished Nature Photonics journal open up new outlooks on ghost imaging in the time domain.
Around a fifth of the energy-saving benefits of fuel-efficient cars are eroded because people end up driving them more, according to a study into British motoring habits over the last 40 years.
Using data from 1970 to 2011, energy experts at the University of Sussex found a long-term 'rebound effect' among British car-drivers of around 20 per cent.
Study identifies harmful PAMP molecules in processed foods that may increase risk of diseases such as coronary artery disease and Type 2 diabetes PAMPs can be found in processed foods such as sausages, burgers, ready meals, cheeses, chocolate and ready-chopped vegetables Removal of PAMP molecules from the diet leads to weight loss and reduction in bad cholesterol Fresh food contains undetectable levels of PAMPs Researchers believe food manufacturers could use method to remove PAMPs and make food healthier without change to taste or cost
The timing of significant Great Barrier Reef coral loss captured by a series of historical photos has been accurately determined for the first time by a University of Queensland)-led study.
Professor Jian-xin Zhao from UQ's School of Earth Sciences said the photos were a powerful visual tool often used to highlight the recent decline of the Great Barrier Reef.
"These photographs taken from the late 19th Century onwards of two inshore Great Barrier Reef locations near Bowen, Queensland, reveal a dramatic loss of coral cover," Professor Zhao said.
Our fear and disgust that cockroaches can quickly squeeze through the tiniest cracks are well justified, say University of California, Berkeley scientists.
Not only can they squish themselves to get into one-tenth-of-an-inch crevices, but once inside they can run at high speed even when flattened in half.
These are just a couple of the creepy findings from a UC Berkeley study of how American cockroaches (Periplaneta americana) penetrate the tightest joints and seams in less than a second.
Scientists have created a crystal structure that boosts the interaction between tiny bursts of light and individual electrons, an advance that could be a significant step toward establishing quantum networks in the future.
The sheet of paper taped to the door of Keith Emery's office tells the story. On the paper is a simple fever chart showing the improvements made in increasing the efficiency of two dozen types of solar cells. Some of the lines marking record efficiencies date to the mid-1970s. Others start much more recently, with the advent of newer technologies.
The discovery of the world's oldest storage of fermented fish in southern Sweden could rewrite the Nordic prehistory with findings indicating a far more complex society than previously thought. The unique discovery by osteologist Adam Boethius from Lund University was made when excavating a 9,200 year-old settlement at what was once a lake in Blekinge, Sweden.
In the one-dimensional (1D), various exotic phenomena are predicted that are totally different from those in the 3D world in which we live. One of the reasons of this is that particles cannot pass each other in 1D. (Fig. 1, in other words, correlation between electrons plays much more important role than those in 3D)
