Research reveals aquatic bacteria more recent move to land
Scientists engineer mosquito immune system to fight malaria
Research by University of Tennessee, Knoxville, faculty has discovered that bacteria's move from sea to land may have occurred much later than thought. It also has revealed that the bacteria may be especially useful in bioenergy research.
Second rare white kiwi hatches in New Zealand
Researchers at the Johns Hopkins Malaria Research Institute have demonstrated that the Anopheles mosquito's innate immune system could be genetically engineered to block the transmission of malaria-causing parasites to humans. In addition, they showed that the genetic modification had limited impact on the mosquito's fitness under laboratory conditions. The researchers' findings are published...
Space station commander captures unprecedented view of comet Lovejoy
A second rare white kiwi has hatched at New Zealand's national wildlife centre, conservation officials announced Friday, months after the world's first hatched in captivity.
Unraveling malaria's genetic mysteries

2011: the Year in Space
No White Christmas for Canadians in 2011
ContributorNetwork - 2011 was an eventful year in space, not the least because the year represented a transition from one era-that of the space shuttle-to whatever lays ahead. It was also a time of uncertainty and even anxiety
Mysterious 'Space Ball' Crashes in Namibia
Most Canadians will not wake up to a white Christmas on December 25 for the first time since Canada's weather office began recording snowfalls in 1955.
Cassini delivers holiday treats from Saturn
SPACE.com - A strange metal ball dropped out of the sky and slammed into the remote grassland of northern Namibia recently, according to press reports.
Cell membrane proteins could provide targets for broader vaccines
(PhysOrg.com) -- No team of reindeer, but radio signals flying clear across the solar system from NASAs Cassini spacecraft have delivered a holiday package of glorious images. The pictures, from Cassinis imaging team, show Saturns largest, most colorful ornament, Titan, and other icy baubles in orbit around this splendid planet.
Gravity's effect on landslides: A strike against Martian water
Vaccines with broader reach might be made by stimulating specialized immune cells to recognize foreign cell membrane proteins that are shared across bacterial species, say researchers from Children's Hospital of Pittsburgh of UPMC and the University of Pittsburgh School of Medicine in a report published online today in Immunity. The approach could be particularly beneficial in preventing infection...
Like monkeys, pigeons can put numbers in order
A pile of sand, gravel, or other granular material takes on a familiar conical shape, with the slope of the pile's walls coming to rest at the static angle of repose. If the material exceeds this angle, it will trigger an avalanche, tumbling down until it comes to rest at the dynamic angle of repose.
More than other drugs, injected meth is associated with an increased risk of attempted suicide
(PhysOrg.com) -- Pigeons are on par with primates in their numerical abilities, according to new University of Otago research appearing in the leading international journal Science.
MSU chemists become the first to solve an 84-year-old theory
The dire physical and mental health effects of injecting methamphetamine are well known, but there's been little research about suicidal behavior and injecting meth. In a recent study, researchers at Columbia University's Mailman School of Public Health and the University of British Columbia found that drug users who inject methamphetamine had an 80% greater risk of attempting suicide than drug...
Netflix CEO's stock options slashed after bad year
The same principle that causes figure skaters to spin faster as they draw their arms into their bodies has now been used by Michigan State University researchers to understand how molecules move energy around following the absorption of light.
New device could bring optical information processing
Netflix CEO Reed Hastings will pay a $1.5 million penalty for blunders that alienated the video subscription service's customers and pulverized its stock.
Quadrantids Will Create Brief, Beautiful Show on Jan. 4
(PhysOrg.com) -- Researchers have created a new type of optical device small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers.
Researcher contends multiple sclerosis is not a disease of the immune system
(PhysOrg.com) -- The 2012 Quadrantids, a little-known meteor shower named after an extinct constellation, will present an excellent chance for hardy souls to start the year off with some late-night meteor watching.
Researchers link multiple sclerosis to different area of brain
An article to be published Friday (Dec. 23) in the December 2011 issue of The Quarterly Review of Biology argues that multiple sclerosis, long viewed as primarily an autoimmune disease, is not actually a disease of the immune system. Dr. Angelique Corthals, a forensic anthropologist and professor at the John Jay College of Criminal Justice in New York, suggests instead that MS is caused by faulty...
Sea cucumbers: Dissolving coral reefs?
Radiology researchers at The University of Texas Health Science Center at Houston (UTHealth) have found evidence that multiple sclerosis affects an area of the brain that controls cognitive, sensory and motor functioning apart from the disabling damage caused by the disease's visible lesions.
When 'clean' is not clean enough
Coral reefs are extremely diverse ecosystems that support enormous biodiversity. But they are at risk. Carbon dioxide emissions are acidifying the ocean, threatening reefs and other marine organisms. New research led by Carnegie's Kenneth Schneider analyzed the role of sea cucumbers in portions of the Great Barrier Reef and determined that their dietary process of dissolving calcium carbonate...
Green Blog: In Internal Canadian Documents, a Warning on Oil Sands
Some solutions are just no-brainers. Take medical backboards, for example, those hard plastic boards used to stabilize patients during emergencies before the patient is lifted onto the gurney and hurried into the ambulance. After each call, technicians scrub down their equipment to avoid exposing the next patient to diseases, microbes or bodily fluids, but despite these efforts, a study conducted...
