The new ‘epidermal’ electronic systems conform to the surface of the skin and may provide a range of healthcare and non-healthcare related functions. John A. Rogers

Game-changing’ printed tattoos may replace hefty medical monitors

Scientists have invented new stick-on ‘tattoos’ that track human heart, brain wave and muscle activity and could one day replace cumbersome medical monitors. Known as an epidermal electronic system (EES…
Methane, emitted in large amounts by wetlands and rice paddies, is being released into the atmosphere at a declining rate but the reason for this remains unclear. Flickr/Kansas Poetry

The case of the disappearing methane

Methane has been floating into the atmosphere at a slower rate over the last three decades but two new papers published in the journal Nature put forward very different theories as to why it’s happening…
Much of academic publishing has shifted online but that has created new costs, the publishers say. Flickr/rosefirerising

Open access and academic journals: the publishers respond

Fees charged by academic publishers to access research journals have caused no small amount of consternation among readers of scholarly research and fuelled the rise of the Open Access movement. As part…

IVF breakthrough could predict fittest embryos

A new method of predicting the chances an embryo will survive has shown promise in tests on mice and could one day be used on humans to boost IVF success rates, UK scientists have said. Many couples undergoing…
Restricting food intake can trigger a process by which certain brain cells start to consume fats within their cellular structure, a study found. Flickr/dierk schaefer

How hunger makes your brain eat itself

Dieting can cause brain cells to eat themselves, a new study has found. In a paper published by the journal Cell Metabolism, US researchers report that tests on mice revealed that hunger triggers a process…

Plastic surgery implant firms when exposed to light

Scientists have invented a new pliable implant that can be injected in liquid form, massaged into shape and hardened up through exposure to light. Fillers are used to make patients look younger, reconstruct…
Brain function in people with schizophrenia improves after 20 minutes of being subjected to very mild, painless electrical current to the brain through electrodes on the scalp, a study found. Flickr/lessherger

Tiny brain shocks may help schizophrenia patients

Around 20 minutes of tiny electric shocks to the scalp may improve brain function in schizophrenia patients, a study has found. Transcranial Direct Current Stimulation (tDCS) involves passing a mild, painless…
Abuse of methamphetamines like ice are at increased risk of developing Parkinson’s disease, a study has found. Flickr/EMSL

Methamphetamine abuse linked to Parkinson’s

People hospitalised for abuse of methamphetamines like crystal meth or ice have a 76% higher risk of developing Parkinson’s disease compared to those with no drug addiction, a study has found. Parkinson’s…
A dog in Queensland has tested positive to Hendra virus, which has killed four of the seven people ever known to be infected. AAP

Dog Hendra case requires fresh research into risks: CSIRO

In a world first, a dog has tested positive to the lethal Hendra virus, prompting the CSIRO to call for fresh research into the risk it could spread from canines to humans. Hendra virus, which is usually…
Scientists are working on ways to make a fingerprint scanner differentiate between a living or dead finger, limiting the chance security will be breached by using an amputated digit. Or a zombie. Flickr/theogeo

How to zombie-proof a fingerprint scanner

High-tech fingerprint scanners may stop most thieves accessing a restricted area, but they have one fatal flaw: scanners can’t tell the difference between a finger that’s living or dead. Or undead. Cases…
The rate at which sea levels are rising can change depending on when or where the measurements were taken, scientists say. Flickr/Brentbat

Sea levels continue to rise, but not uniformly: CSIRO

Global average sea levels continue to rise but readings vary greatly depending on when and where they are taken, a leading expert on coastal impacts of climate change has said, warning that selective sea…

In pictures: 30 years of the Space Shuttle program

At approximately 8pm last night (AEST), the Space Shuttle Atlantis touched down at the Kennedy Space Centre for the final time. The 14-day mission to the International Space Station (ISS) was the 135th…
Is there a link between the function of the female orgasm and producing more handsome offspring? Flickr/TaniaSaiz

The female orgasm: brought to you by natural selection?

Women orgasm more readily during sex with a handsome partner, a study of heterosexual couples has found, with researchers concluding the female orgasm may be linked to an evolutionary urge to produce ‘quality…

How not to win at rock-paper-scissors

Humans instinctively copy their opponents while playing rock, paper, scissors, suggesting the urge to imitate others is deeply etched in the subconscious, a study has found. In an experiment conducted…

LulzSec hacks the hackers at News International

An attack by computer hacker group LulzSec has shut down over 1000 websites owned by Rupert Murdoch’s News International, after the group posted a fake story on the website of Murdoch tabloid The Sun declaring…
Locking carbon dioxide in soils and crops also stimulates emission of other greenhouse gases like methane and nitrous oxide, a study found, meaning the capacity of land ecosystems to slow climate warming may have been overestimated. Flickr/AndyCarvin

Land carbon offset capacity may have been overestimated

The ability of land ecosystems like crops and soils to slow down climate change may have been overestimated because some of these ‘carbon sinks’ actually emit more greenhouse gases than first thought…
A survey of 140 economists found 60% were in favour of the Gillard government’s carbon tax policy. AAP

Economists back carbon tax package

A survey of 145 economists released today found that 60% believe the Gillard government’s carbon tax is good economic policy. The carbon tax package, announced on Sunday, penalises 500 heavy polluters…
