ScienceDaily... An enzyme responsible for a crucial step in the production of cholesterol has ten segments that span the cell membrane in which it is embedded. These contain two pockets the enzyme uses to bring the reactants together. Credit: Laboratory of Cell Biology at The Rockefeller University/Nature [Click to enlarge image] In spite of its dangerous reputation, cholesterol is in fact an essential component of human cells. Manufactured by the cells themselves, it serves to stiffen the cell's membrane, helping to shape the cell and protect it. By mapping the structure of a key enzyme involved in cholesterol production, Rockefeller University researchers and a colleague in Italy ...

Epoch Times... The practice of physically stimulating the brain in order to alleviate symptoms of illness and injury has been around since the early 20th century. For example, electroconvulsive therapy (ECT) is still used to alleviate symptoms of depression. However, perhaps in part due to negative connotations associated with ECT, in modern medicine treatment of psychological disorders have tended to use other forms of intervention. These now mostly involve drugs or therapy. However, a recent study, published in the journal Science, sees a return to this idea of stimulating brain regions to improve brain function. Researchers at Northwestern University have shown that targeted ...

ScienceDaily... Fusion energy almost sounds too good to be true -- zero greenhouse gas emissions, no long-lived radioactive waste, a nearly unlimited fuel supply. Perhaps the biggest roadblock to adopting fusion energy is that the economics haven't penciled out. Fusion power designs aren't cheap enough to outperform systems that use fossil fuels such as coal and natural gas. University of Washington engineers hope to change that. They have designed a concept for a fusion reactor that, when scaled up to the size of a large electrical power plant, would rival costs for a new coal-fired plant with similar electrical output. The team published its reactor design and cost-analysis ...

SwissInfo... Entrepreneurs have helped develop a new system designed to detect radiological threats, which is being tested at ports across Europe. (SRF ECO, swissinfo.ch) Monitors hidden inside a van can single out freight containing substances such as uranium, plutonium, or radiological components for "dirty bombs”. These are weapons that combine radioactive material with conventional explosives. The information gathered allows operators to exclude the possibility of a detected plutonium source being a “ready-to-go” nuclear weapon. The system is the first of its type in the world to combine fast and thermal neutron detection. The technologies were tested at CERN, the ...

US Govt Holds Patent on Ebola, But Researcher Rejects Conspiracy Theories Thursday, 09 Oct 2014 11:24 AM By Charlotte Libov Word is spreading on Internet sites that the U.S. government will profit from the Ebola crisis because a patent it holds on the virus would allow it to make money on treatments. However, a top Ebola researcher tells Newsmax Health that these conspiracy theories are off base. It’s true that the U.S. Centers for Disease Control and Prevention does hold a patent on one strain of Ebola. However, it is not the type that is causing the current outbreak, said David Sanders, professor of biological sciences at Purdue University. What’s more, the government ...

ScienceAlert For the first time, Australian scientists have shown that in flies, a female’s previous sexual partner can affect how her offspring from another male turns out. The idea of previous sexual partners influencing how another man’s offspring will turn out was discredited in humans when we started to understand genetics in the early 20th century. But life on Earth is so incredibly diverse, and just because humans aren't affected by this phenomenon doesn't mean other species aren't. To investigate this, a team of scientists from the University of New South Wales (UNSW) worked with different sized male neriid flies to see if previous mates would influence ...

ScienceDaily... Pity the poor lithium ion. Drawn relentlessly by its electrical charge, it surges from anode to cathode and back again, shouldering its way through an elaborate molecular obstacle course. This journey is essential to powering everything from cell phones to cordless power tools. Yet, no one really understands what goes on at the atomic scale as lithium ion batteries are used and recharged, over and over again. Michigan Technological University researcher Reza Shahbazian-Yassar has made it his business to better map the ion's long, strange trip -- and perhaps make it smoother and easier. His ultimate aim: to make better batteries, with more power and a longer life. ...
Scientists have created the most effective “invisibility cloak” so far, and you can make one for $100

ScienceAlert... Created by scientists at the University of Rochester in New York, the device can hide large objects from sight using cheap and readily available lenses. “There’ve been many high tech approaches to cloaking and the basic idea behind these is to take light and have it pass around something as if it isn’t there, often using high-tech or exotic materials,” said John Howell, a professor of physics at the University of Rochester in a press release. But while it works like an invisibility cloak, it looks more like something your optometrist would use to check your eyes - and when something is placed behind the layered lens, it disappears from view, leaving ...
Study Finds Treated Fracking Wastewater Still Too Toxic

One of the biggest concerns about hydraulic fracturing, or fracking, is that the vast amount of wastewater produced by the process of extracting oil and gas from shale rock deep underground is incredibly toxic. Most often, the wastewater is injected into disposal wells deep underground. But a process does exist to convert contaminated water into drinking water that involves running it through wastewater treatment plants and into rivers. Now a new report says that treated wastewater could be fouling drinking water supplies. In an article published in Environmental Science & Technology -- the journal of the American Chemical Society -- a team of researchers acknowledged that the ...
