Scientists regenerate 30,000 year-old plant

Fruit seeds stored away by squirrels more than 30,000 years ago and found in Siberian permafrost have been regenerated into full flowering plants by scientists in Russia, a new study has revealed. The seeds of the herbaceous Silene stenophylla are far and away the oldest plant tissue to have been…

Stark warning emerges from summit: science is ‘under siege’

A stark theme emerged from an annual scientific get-together in Vancouver: the world must be helped to believe in science again or it could be too late to save our planet. Science is “under siege,” top academics and educators were warned repeatedly at the American Association for the Advancement of…

Science overturns view of humans as naturally ‘nasty’

VANCOUVER, Canada — Biological research increasingly debunks the view of humanity as competitive, aggressive and brutish, a leading specialist in primate behavior told a major science conference. “Humans have a lot of pro-social tendencies,” Frans de Waal, a biologist at Emory University in Atlanta, told the annual meeting of the…

Animal diseases increasingly plague the oceans

VANCOUVER — When dead sea mammals started washing ashore on Canada’s west coast in greater numbers, marine biologist Andrew Trites was distressed to find that domestic animal diseases were killing them.

‘Artificial leaf’ eyed as holy grail in energy research

Turbo-charging photosynthesis – by which plants and bacteria turn sunlight into food and energy — in an “artificial leaf” could yield a vast commercial power source, scientists said. Photosynthesis is”unfortunately not very efficient,” Anne Jones, assistant professor and biochemist at Arizona State University, told the American Association for the Advancement of Science meetingin Vancouver this…

First ‘test-tube’ hamburger to be produced this year

The world’s first “test-tube” meat, a hamburger made from a cow’s stem cells, will be produced this fall, Dutch scientist Mark Post told a major science conference on Sunday. Post’s aim is to invent an efficient way to produce skeletal muscle tissue in a laboratory that exactly mimics meat, and…

Santorum: Prenatal testing is to ‘encourage abortions’

Republican presidential candidate Rick Santorum on Sunday suggested that “Obamacare” required free prenatal testing coverage because President Barack Obama wanted to see more disabled babies aborted. The former Pennsylvania senators had told supporters on Saturday that the Affordable Care Act just created the requirement “because free prenatal testing ends up…

Single-atom transistor busts the records

PARIS — Researchers in Australia said on Sunday they had made with pinpoint accuracy a working transistor consisting of a single atom, marking a major stride towards next-generation computing. The device comprises a single phosphorus atom, etched into a silicon bed, with “gates” to control electrical flow and metallic contacts…
