Mobs rule for great tit neighbors Posted: 01 May 2012 06:20 PM PDT Great tits are more likely to join defensive mobs with birds in nearby nests that are 'familiar neighbours' rather than new arrivals, new research has found.

Skeletons found at mass burial site in Oxford could be 10th-century Viking raiders Posted: 01 May 2012 05:48 PM PDT Thirty-seven skeletons found in a mass burial site in the grounds of St John's College may not be who they initially seemed, according to Oxford researchers studying the remains.

Jurassic pain: Giant 'flea-like' insects plagued dinosaurs 165 million years ago Posted: 01 May 2012 01:27 PM PDT It takes a gutsy insect to sneak up on a huge dinosaur while it sleeps, crawl onto its soft underbelly and give it a bite that might have felt like a needle going in -- but giant "flea-like" animals, possibly the oldest of their type ever discovered, probably did just that.

Use of public and private dollars for scaling up clean energy needs a reality check, say scholars Posted: 01 May 2012 01:27 PM PDT In a post-Solyndra, budget-constrained world, the transition to a decarbonized energy system faces great hurdles. Overcoming these hurdles will require smarter and more focused policies. Two writers outline their visions in a pair of high-profile analyses.

Chemist delivers cleaner air with novel carbon-capture technique Posted: 01 May 2012 01:25 PM PDT Researchers are exploring an increasingly versatile class of materials known as metal-organic frameworks (MOF). An emerging technology in the scientific community, MOF are porous crystalline polymers made up of metal ions or metal-containing components and organic ligands. Chemists are assembling MOF materials with a profound potential for providing for cleaner energy around the globe.

Bigger gorillas better at attracting mates and raising young Posted: 01 May 2012 10:44 AM PDT Conservationists have found that larger male gorillas living in the rainforests of Congo seem to be more successful than smaller ones at attracting mates and even raising young.

Global warming: New research blames economic growth Posted: 01 May 2012 10:43 AM PDT It's a message no one wants to hear: to slow down global warming, we'll either have to put the brakes on economic growth or transform the way the world's economies work. That's the implication of an innovative study examining the evolution of atmospheric CO2, the most likely cause of climate change.

Resveratrol: Study resolves controversy on life-extending red wine ingredient, restores hope for anti-aging pill Posted: 01 May 2012 10:42 AM PDT A new study appears to offer vindication for an approach to anti-aging drugs that has been at the center of heated scientific debate in recent years. The new findings show for the first time that the metabolic benefits of the red wine ingredient known as resveratrol evaporate in mice that lack the famed longevity gene SIRT1.

Garlic compound fights source of food-borne illness better than antibiotics Posted: 01 May 2012 10:42 AM PDT A compound in garlic is 100 times more effective than two popular antibiotics at fighting the Campylobacter bacterium, one of the most common causes of intestinal illness. The discovery opens the door to new treatments for raw and processed meats and food preparation surfaces.

Were dinosaurs undergoing long-term decline before mass extinction? Posted: 01 May 2012 10:41 AM PDT Despite years of intensive research about the extinction of non-avian dinosaurs about 65.5 million years ago, a fundamental question remains: Were dinosaurs already undergoing a long-term decline before an asteroid hit at the end of the Cretaceous? A new study suggests that in general, large-bodied, "bulk-feeding" herbivores were declining during the last 12 million years of the Cretaceous. But carnivorous dinosaurs and mid-sized herbivores were not.

Rare glimpse into great blue heron nest Posted: 01 May 2012 06:59 AM PDT In a first for technology and for bird watching, thousands of people watched live this weekend as a tiny Great Blue Heron emerged from an egg in between its father's gigantic feet. Viewers around the world are now able to follow the surprising lives of herons, including rare views still little known to science.

High-powered microscopes reveal inner workings of sex cells Posted: 01 May 2012 05:55 AM PDT Scientists using high-powered microscopes have made a stunning observation of the architecture within a cell – and identified for the first time how the architecture changes during the formation of gametes, also known as sex cells, in order to successfully complete  the process.

Gene involved in sperm-to-egg binding is key to fertility in mammals Posted: 30 Apr 2012 07:39 PM PDT Scientists looking at fertility in mice, have discovered for the first time that the gene, which makes a protein called PDILT, enables sperm to bind to an egg, a process essential to fertilization.
