e=mc2: 103 years on, Einstein proved right

Friday, 21 November 2008

It's taken more than a century, but Einstein's celebrated formula e=mc2 has finally been corroborated, thanks to a heroic computational effort by French, German and Hungarian physicists.


LLNL laser facility

Laser creates billions of antimatter particles

Wednesday, 19 November 2008

By shooting a laser through a gold disc no bigger than the head of a drawing pin, physicists have created more than 100 billion particles of antimatter.


Large Hadron Collider

LHC restart delayed even further

Tuesday, 18 November 2008

Europe's giant atom-smasher, which broke down only days after being switched on with great fanfare, is not expected to restart before the middle of next year, say operators.


Gem stones

Earth's minerals have evolved over time

Monday, 17 November 2008

Geologists have found that Earth's 'mineral kingdom' has co-evolved with life, and that up to two thirds of the more than 4,000 known types of minerals can linked to biological activity.


Pierre Auger Observatory

Vast observatory to solve cosmic mysteries

Monday, 17 November 2008

Scientists in western Argentina inaugurated on Friday the world's largest astronomical observatory, hoping to unlock the mysteries of high energy cosmic rays that bombard the Earth.


Ice age

Global warming to stave off next Ice Age

Thursday, 13 November 2008

Scheduled shifts in Earth's orbit are due to plunge the planet into an Ice Age perhaps 10,000 years from now, but the event may be averted by man-made greenhouse gases, say scientists.


Siberian waterfall

Another potent greenhouse gas on the rise

Thursday, 30 October 2008

The amount of methane in Earth's atmosphere shot up in 2007. This brings to an end a decade in which levels were relatively stable, says a report in the journal Geophysical Review Letters.

Sticky tape gives off X-rays

Thursday, 23 October 2008

Unwinding household sticky tape in a vacuum emits radiation strong enough to X-ray a human figure, according to a new study in the British journal Nature.


Taiwan's LiWu River

Cyclones lock away carbon, study says

Monday, 20 October 2008

Tropical cyclones transfer carbon dioxide from land to the deep ocean, where it may get locked-away long term. This could act to temper global warming as it increases the frequency and intensity of cyclones.


Martin Chalfie

Nobel chemistry laureate finds news online

Thursday, 9 October 2008

U.S. scientist Martin Chalfie went on the internet to find out he was one of three co-winners of the 2008 Nobel Prize for chemistry, he said, after ignoring a telephone ringing he thought came from next door.


Toshihide Maskawa

Standard Model work wins Nobel Physics Prize

Wednesday, 8 October 2008

Makoto Kobayashi and Toshihide Maskawa of Japan and Yoichiro Nambu of the United States won the 2008 Nobel Physics Prize Tuesday for groundbreaking theoretical work in fundamental particles.


Graphene sheets

Super-thin material has massive energy storage potential

Monday, 29 September 2008

A material consisting of sheets of carbon just one atom thick, could be very useful for storing renewable energy, says a new study.


OPAL

ANSTO: Opal reactor leaking water, but safe

Friday, 26 September 2008

Australia's OPAL nuclear reactor is facing new criticism that a fault, allowing water to seep internally, renders it unsafe. This follows a fuel issue that already forced the reactor to close for ten months.


LHC magnet

LHC out of action until 2009

Wednesday, 24 September 2008

The multi-billion-dollar machine designed to shed light on the nature of the universe will be out of action until at least the second quarter of 2009, says CERN.


LHC

Large Hadron Collider down for two months

Monday, 22 September 2008

The world's largest atom-smasher has been shut down for two months following a helium leak, just ten days after it began its quest to probe the secrets of the universe.
