Scientists have demonstrated that a bent silicon crystal can bend the paths of focused, very energetic electron beams much more than magnets used today. The method could be of interest for particle accelerator applications such as next-generation X-ray lasers that will help scientists unravel atomic structures and motions in unprecedented detail.
A deadly fungus responsible for the extinction of more than 200 amphibian species worldwide has coexisted harmlessly with animals in Illinois and Korea for more than a century, a pair of studies have found. read more
Large facilities like big box stores or hospitals could keep the lights on by using a fuel cell that runs off the natural gas that already flows in pipelines below most city streets. read more
The earliest known record of the genus Homo -- the human genus -- represented by a lower jaw with teeth, recently found in the Afar region of Ethiopia, dates to between 2.8 and 2.75 million years ago, according to an international team of geoscientists and anthropologists. Show More Summary
Ted Galen Carpenter Alliances tend to entangle America in confrontations that have little or no relevance to the security and liberty of the republic. A prime example of that problem is the ongoing, bitter dispute between Japan and South Korea over some largely uninhabited rocks and the waters surrounding them. Show More Summary
Steve H. Hanke Senator Rand Paul (R-KY) introduced a bill (S.264) which is popularly known as “Audit the Fed” (ATF). The bill picked up 30 initial co-sponsors. Although the Fed is already extensively audited in the accounting sense of the term, the ATF bill would expand the scope and scale of Fed auditing. Show More Summary
Can you guess the language being spoken? Takes a while to load (at least it did for me), but worth it. I got fewer wrong than I would have expected; I was not at all surprised that one of the ones I missed was European Portuguese (see this LH post). Thanks, Bathrobe!
Statesmanship. Gravitas. Moral Clarity. Wisdom. Courage. Great oratory. All in stark contrast to that jayvee player, Obama the Feckless.
Recent research has uncovered the remains of an ancient town and burial complex that date to the Neolithic and Bronze Age. In addition to the Neolithic 'spooning' couple that has been highlighted in recent news articles, the team also uncovered several other burials and the remains of an ancient village that suggest the bay was an important center in ancient times.
A new research paper reveals how specially prepared carbon foam can be used in the detection of neutrons emitted by radioactive materials -- a task of critical importance to homeland security, as well as industry and safety.
Researchers have identified electrical charge-induced changes in the structure and bonding of graphitic carbon electrodes that may one day affect the way energy is stored. The research could lead to an improvement in the capacity and...Show More Summary
Researchers have found a way to increase the production of fuels and other chemicals from biomass fermented by yeast without the need of environmentally harsh pre-treatments or expensive enzyme cocktails.
You can see it through a telescope, or watch a documentary about it, but you can't stick your nose out and take a whiff. Speaking of Chemistry returns this week to answer the very important question, "What does space smell like?" Matt Davenport, Ph.D., reveals the stinky secrets of the cosmos from the people who have been there.
When scientists develop a full quantum computer, the world of computing will undergo a revolution of sophistication, speed and energy efficiency that will make even our beefiest conventional machines seem like Stone Age clunkers by comparison.
For the first time, a study reveals exactly how mutations associated with the most common form of inherited Alzheimer's disease produce the disorder's devastating effects. The paper upends conventional thinking about the effects of Alzheimer's-associated mutations in the presenilin genes and provides an explanation for the failure of drugs designed to block presenilin activity.
IRRADIATION PRODUCTS ON DWARF PLANET MAKEMAKE Authors:Brown et alAbstract:The dark, reddish tinged surfaces of icy bodies in the outer solar system are usually attributed to the long term irradiation of simple hydrocarbons leading to the breaking of C–H bonds, loss of hydrogen, and the production of long carbon chains.

Some of the galaxies in our universe are veritable star nurseries. For example, our own Milky Way produces, on average, at least one new star every year. Others went barren years ago, now producing few if any new stars. Why that happens is a question that has dogged astronomers for years. Show More Summary
The more copies of a genome a cell holds, the more adaptable those cells are, scientists have discovered. This may have implications for cancer's evolution and adaptation.
Roger Pilon Among the countless analyses now going on of today’s 84 minutes of oral argument before the Supreme Court in King v. Burwell, perhaps none is more perceptive than that offered by SCOTUSblog’s Lyle Denniston, the dean of Supreme Court reporters. Show More Summary
A pair of studies show that the deadly fungus Batrachochytrium dendrobatidis, responsible for the extinction of more than 200 amphibian species worldwide, has coexisted harmlessly with animals in Illinois and Korea for more than a century. Show More Summary
