Weird weather pushes Greenland to worst ice loss on record

A new study has calculated that the Greenland ice sheet lost hundreds of billions of tons of ice last year, marking the biggest drop in its ice mass since records began in 1948. And warm weather alone wasn’t to blame – the team found that unusual press… Continue reading Weird weather pushes Greenland to worst ice loss on record→

Metal-air scavenger robot “eats” aluminum to power itself

Batteries have served us well over decades, but as electronic devices shrink they’re becoming too heavy and inefficient for some uses. Now, researchers at the University of Pennsylvania have developed a new type of robot that powers itself by “eating” … Continue reading Metal-air scavenger robot “eats” aluminum to power itself→

Two new solar cells break records, including highest efficiency ever

Solar cells are constantly improving on the road to maximum efficiency. Now, three records have been broken by two different devices, including one that pushes the highest overall solar conversion efficiency towards the 50-percent mark.Continue Reading… Continue reading Two new solar cells break records, including highest efficiency ever→

Cancer study stumbles onto potential way to regenerate heart cells

Unfortunately for heart attack patients, heart cells don’t naturally replenish, so this vital organ stays permanently damaged. But now, Cambridge researchers have stumbled onto a gene that appears to trigger heart cell regeneration – and they did so by… Continue reading Cancer study stumbles onto potential way to regenerate heart cells→

Deep sea expedition uncovers 30 new species, plus longest-known animal

Forget space – the oceans are Earth’s final frontier. Even after centuries of exploration we’re still only just scratching the surface of what lives down there. The latest case in point is a diving expedition off the coast of Western Australia, which h… Continue reading Deep sea expedition uncovers 30 new species, plus longest-known animal→

Astronomers spot the brightest and most energetic supernova on record

Astronomers have spotted the brightest and most energetic supernova ever recorded. The event, known as SN2016aps, may have been the result of two stars merging and then exploding, before the dust had completely settled.Continue ReadingCategory: Space, … Continue reading Astronomers spot the brightest and most energetic supernova on record→

‘Oumuamua may be a piece of a planet torn to shreds by a star

‘Oumuamua, the first interstellar interloper detected passing through our solar system, raised many questions when it was discovered. According to a new model, the object’s unusual shape and trajectory may be the result of a devastating close encounter… Continue reading ‘Oumuamua may be a piece of a planet torn to shreds by a star→

Biohybrid battery harvests energy from electric bacteria

Some bacteria are known to produce their own electricity, which could make them useful in batteries and fuel cells. But so far, attempts have been inefficient and inflexible. Now, researchers at Karlsruhe Institute of Technology (KIT) have created a “b… Continue reading Biohybrid battery harvests energy from electric bacteria→

Parts of the universe may be expanding faster than others

One of the core components of cosmology is the understanding that the universe is expanding evenly in all directions. It was predicted by theory decades ago, and supported by measurements of the cosmic microwave background. But new X-ray observations n… Continue reading Parts of the universe may be expanding faster than others→

Cancer-killing nanoparticles don disguises to sneak into the brain

Brain cancers are particularly insidious for many reasons, not least of which is that the brain’s own defense mechanism often prevents treatment. But a new experimental technique has shown success in mice, with carbon nanoparticles able to sneak throug… Continue reading Cancer-killing nanoparticles don disguises to sneak into the brain→
