"Heaven is a fairy story for people afraid of the dark, the eminent British theoretical physicist Stephen Hawking said in an interview published on Monday."

"Seagrasses around the world are disappearing, with some species now threatened with extinction. The first global survey of individual seagrass species has found that 14% are at risk of going extinct."

"A digital camera that allows photographers to focus their pictures after taking them has gone on sale. Rather than recording a single version of an image, the Lytro captures data about the intensity and direction of all the light entering its lenses."

"The latest study, carried out at the Haukeland University Hospital in Bergen, built on the previous discovery by testing 30 patients with CFS. Half were given two doses of Rituximab, a cancer drug which eliminates a type of white blood cell, while the other half were given a fake treatment. In those patients receiving the drug, 67% reported an improvement in a score of their fatigue levels. Just 13% showed any improvement in the sham group. "

"A report released late Thursday in London and discussed Friday at the U.N. climate conference in South Africa said that - in theory - reflecting a small amount of sunlight back into space before it strike's the Earth's surface would have an immediate and dramatic effect. Within a few years, global temperatures would return to levels of 250 years ago, before the industrial revolution began dumping carbon dioxide into the air, trapping heat and causing temperatures to rise."

"Coffee addicts have an excuse for blaming their genes. According to new research, genetic factors could explain why some people consume large amounts of caffeine. US researchers scanned genetic variations in over 40,000 individuals to search for links with high caffeine intake."

"Every year, about 1,000 women in the UK suffer from what is called postpartum psychosis. Most of them will need several weeks in hospital to help them recover but, because of the stigma of mental illness, it is not often talked about. "

"Most massive galaxies, including our own Milky Way, are thought to harbour supermassive black holes at their centres. But these newly discovered black holes are much bigger than would be predicted by extrapolating from observations from their host galaxies. This suggests that the factors influencing the growth of the largest galaxies and their black holes differ from those influencing smaller galaxies. The findings come from observations of two nearby galaxies: NGC 3842 and NGC 4889."

"A survey of about 600 scientists published this week found that a majority think it's time to consider conservation triage - focusing resources on animals that can realistically be saved, and giving up on the rest. Those that fall into the too-expensive-to-save category, it has been suggested, might include the panda and the tiger."

"Claims that the costs of wind farms and other low-carbon technology will lead to sharp rises in fuel bills are wrong, government advisers say. The Committee on Climate Change (CCC) says increases in bills over the past few years have been largely due to higher wholesale gas costs."

"Nearly 20% of women in the US are raped or suffer attempted rape at some point in their lives, a US study says. Even more women, estimated at 25%, have been attacked by a partner or husband, the Centers for Disease Control said."

"They think they are of a kind never before discovered. The well-preserved organisms from the Ordovician period, which began about 495m years ago, lived in what is now the town of Llandrindod Wells, which was partially under water. Scientists believe they shed new light on how ocean communities have evolved."

"Todd Rider, a research scientist at the Massachusetts Institute of Technology, is developing an antiviral drug called Draco, which has proven successful against all 15 viruses to which it has been applied in lab trials with human tissue and mice. These include the common cold, H1N1 or swine flu, a polio virus, dengue fever and the notorious and fatal Ebola virus. To produce it, Mr Rider took an unusual approach, "wiring together" two natural proteins - one that detects virus entry, and another that acts as a suicide switch that kills the infected cell."

"In the few, limited tests conducted outside the United States, BPS shows estrogenic activity - not as strong as BPA, but not a good sign. BPS is now used in the United States to make PES (polyethersulfone) plastic. Some baby bottles marketed as BPA-free use PES plastic. Bisphenols are shaping up to be a dysfunctional family of chemicals. BPAF is BPA's fluorinated twin. It is used in electronic devices, optical fibers and more. New studies have found BPAF to be an even more potent endocrine disrupter than BPA. Bisphenol B and Bisphenol F are other variants used instead of BPA in various products. In the limited testing done on those chemicals in other countries, scientists found Bisphenol B to be more potent than BPA in stimulating breast cancer cells. "

"Dr. Levine, a Howard Hughes Medical Institute (HHMI) investigator at the medical center, decided to focus on one specific health effect of exercise -- the ability of exercise to prevent blood sugar abnormalities in the face of a high-fat diet. Her mouse study provides the first evidence that exercise stimulates autophagy."

"Researchers from the University of Michigan discovered that a session of aerobic exercise increases storage of fat in muscle, which actually improves insulin sensitivity. Low insulin sensitivity, or insulin resistance, is an impaired ability of the body to take up sugar from the blood, which can lead to high blood sugar and diabetes."

"Harps employs an indirect method of detection that infers the existence of orbiting planets from the way their gravity makes a parent star appear to twitch in its motion across the sky. "Our new observations with Harps mean that about 40% of all red dwarf stars have a super-Earth orbiting in the habitable zone where liquid water can exist on the surface of the planet," said team leader Xavier Bonfils from the Observatoire des Sciences de l'Univers de Grenoble, France. "Because red dwarfs are so common - there are about 160 billion of them in the Milky Way - this leads us to the astonishing result that there are tens of billions of these planets in our galaxy alone.""

"Think the school you chose for your child is good? Better than that academic straggler just down the road? Think again. A new study is raising questions about the information parents commonly use to chose a school for their children, especially in provinces like Alberta and British Columbia, where families commonly shop around for an education."

Throw-away Buildings Thermal Window Failure: How it Happens Virtually all glass condominium towers feature window wall systems (floor-to-ceiling walls of glass) enclosing the entire facade. Window walls yield spectacular views, but owners who buy a condo unit for the view may not realize that they're relying on a couple of panes of glass separated by less than an inch of insulated space to protect them from the elements. That insulated barrier will degrade over time, even as energy costs increase. On some buildings, five per cent of the thermal windows may have failed before they're even delivered to the construction site. Another 10 - 15 per cent will fail by the 20-year mark as they're exposed to the physics of heat expansion. By the 25 year-mark, a growing number will fail every year.

"Building scientists have known for a long time that glass-walled structures are less energy efficient than the stone and concrete buildings that were put up forty of fifty years ago. But the market demand for glass combined with the relatively low cost of glass-wall construction means the building industry has been happy to oblige."
