NASA spaceport breaks ground for shuttle display
NASA's retired space shuttle Atlantis is a step closer to completing its final journey. -
20:24Medications or biologic agents that target T-cells, white blood cells involved in the body's immune system, appear to offer significant benefit to patients suffering from psoriatic arthritis (PsA), a type of arthritis that affects up to 48 percent of patients with the skin disease psoriasis, according to a new review article in the Journal of the American Academy of Orthopaedic Surgeons (JAAOS). About 7.5 million Americans – roughly 2.2 percent of the population – have psoriasis, an autoimmune disease that causes red, flaky skin.

20:24A novel technique has been developed and demonstrated at Penn State University to map the proteins that read and regulate chromosomes -- the string-like structures inside cells that carry genes. The specific order in which these proteins attach DNA-containing nucleosomes along the chromosome determines whether a brain cell, a liver cell, or a cancer cell is formed. Until now, it has been exceedingly difficult to determine exactly where such proteins bind to the chromosome, and therefore how they work. The new technique precisely pinpoints their location, and has the potential to take high-resolution snapshots of proteins as they regulate or miss-regulate an entire genome.

20:24A new research project into the role of sport in rehabilitating young prisoners has found that sport can be effective in reducing the reconviction rate of offenders.

20:24The accumulation of α-synuclein, a small, negatively charged protein, in neural cells, is one of the hallmarks of Parkinson's disease. It has been suggested that oligomeric α-synuclein causes membranes to become permeable, or to form channels on the outer cell membrane. Now, a group of scientists from Sweden has found a way to reliably replicate α-synuclein aggregation on cell membranes to investigate how different forms of α-synuclein interact with membranes under different conditions and to learn if any of the α-synuclein species can penetrate these membranes. Their results are published in the current issue of the Journal of Parkinson's Disease.

20:24In 2005, news first broke that researchers in Scotland found unexpectedly low rates of cancer among diabetics taking metformin, a drug commonly prescribed to patients with Type II diabetes. Many follow-up studies reported similar findings, some suggesting as much as a 50-per-cent reduction in risk.

20:24A new study shows pregnant women exposed to armed conflict have a higher risk of giving birth to underweight babies, a result that could change the way aid is delivered to developing countries.

20:24Harvard scientists have developed the fullest picture yet of how neurons in the brain interact to reinforce behaviors ranging from learning to drug use, a finding that might open the door to possible breakthroughs in the treatment of addiction.

20:24Even the tiniest microscopic organisms make waves when they swim. In fact, dealing with these waves is a fact of life for the ulcer-causing bacteria H. pylori.

20:24If you are unhappy at work, it could be partly due to your boss' management style, according to a new study by Dr. Nicolas Gillet, from the Université François Rabelais in Tours in France, and his team. Both over-controlling managers who use threats as a way to motivate employees, and organizations that do not appear to value individuals' contributions, frustrate our basic needs for autonomy, competence, and relatedness (how we relate to others). This, in turn, is likely to have a negative impact on our well-being at work. The research is published online in Springer's Journal of Business and Psychology.

20:24The United States will Wednesday reject the proposed Keystone XL oil pipeline from Canada, a politically charged project that is bitterly opposed by environmentalists, news reports said.

20:24(AP) -- January 18 is a date that will live in ignorance, as Wikipedia started a 24-hour blackout of its English-language articles, joining other sites in a protest of pending U.S. legislation aimed at shutting down sites that share pirated movies and other content.

Astronomers Aim To Take First Picture of Black Hole
Taking a picture of a black hole, an object so gravitationally bound that not even photons of light can escape, sounds like an oxymoron, but astronomers this week will attempt to do just that. -

Important gene-regulation proteins pinpointed by new method
A novel technique precisely pinpoints the location of proteins that read and regulate chromosomes. The order of these proteins determines whether a brain cell, a liver cell, or a cancer cell is formed. Until now, it has been exceedingly difficult to determine exactly where such proteins bind to the chromosome, and therefore how they work.
