Bad weather delays Japan asteroid probe lift off

Bad weather will delay the launch of a Japanese space probe on a six-year mission to mine a distant asteroid, just weeks after a European spacecraft's historic landing on a comet captivated the world.

Staying warm: The hot gas in clusters of galaxies

Most galaxies lie in clusters, groupings of a few to many thousands of galaxies. Our Milky Way galaxy itself is a member of the "Local Group," a band of about fifty galaxies whose other large member is the Andromeda Galaxy about 2.3 million light-years away. The closest large cluster of galaxies to us is the Virgo Cluster, about 50 million light-years away, with about 2000 members.

Venus Express spacecraft, low on fuel, does delicate dance above doom below

It's been an interesting year for Venus Express. A few months ago, controllers deliberately dipped the spacecraft into the atmosphere of the planet—for science purposes, of course. The daring maneuver was approved because the spacecraft is near the end of its mission. It's nearly out of fuel and will fall into Venus—sometime. Likely in 2015. No one knows exactly when, however.

JUICE mission gets green light for next stage of development

The European Space Agency's JUICE (JUpiter ICy moons Explorer) mission has been given the green light to proceed to the next stage of development. This approval is a milestone for the mission, which aims to launch in 2022 to explore Jupiter and its potentially habitable icy moons.

Orion on track at T MINUS 1 Week to first blastoff

At T MINUS 1 Week on this Thanksgiving Holiday, all launch processing events remain on track for the first blast off of NASA's new Orion crew vehicle on Dec. 4, 2014 which marks the first step on the long road towards sending Humans to Mars in the 2030s.

'Meteoric smoke': Comet siding spring could alter Mars chemistry permanently

Feeling lucky? Events such as the Comet Siding Spring approach by Mars in October only happen about once every eight million years, according to NASA.

Duality in the human genome

Humans don't like being alone, and their genes are no different. Together we are stronger, and the two versions of a gene – one from each parent – need each other. Scientists at the Max Planck Institute for Molecular Genetics in Berlin have analysed the genetic makeup of several hundred people and decoded the genetic information on the two sets of chromosomes separately. In this relatively small group alone they found millions of different gene forms. The results also show that genetic mutations do not occur randomly in the two parental chromosome sets and that they are distributed in the same ratio in everyone.

'Chatty' cells help build the brain

The cerebral cortex, which controls higher processes such as perception, thought and cognition, is the most complex structure in the mammalian central nervous system. Although much is known about the intricate structure of this brain region, the processes governing its formation remain uncertain. Research led by Carina Hanashima from the RIKEN Center for Developmental Biology has now uncovered how feedback between cells, as well as molecular factors, helps shape cortical development during mouse embryogenesis.

Sperm can carry Ebola for 82 days: WHO

Sperm can carry the Ebola virus for at least 82 days, the World Health Organization said Friday, urging men recovering from the disease to use condoms for three months after the onset of symptoms.

Thai parliament votes to ban commercial surrogacy (Update)

Thailand's parliament has voted to ban commercial surrogacy after outrage erupted over the unregulated industry following a series scandals including the case of an Australian couple accused of abandoning a baby with Down's syndrome.

Behavioral interventions to prevent progression to diabetes equally effective in men and women

Behavioural and drug interventions aiming to prevent people with prediabetes progressing to full blown type 2 diabetes are equally effective for both sexes at preventing progression and reducing weight, according to a new systematic review and meta-analysis. The research is by Dr Anna Glechner, Danube University Krems, Austria, and Dr Jürgen Harreiter, Medical University of Vienna, Austria, and colleagues.

British-led scientists trial 15-minute Ebola test in Guinea

British scientists announced trials on a 15-minute Ebola test in Guinea as France's Francois Hollande arrived in Conakry on Friday, becoming the first Western leader to visit one of the countries devastated by the epidemic.

How do Tourette's patients react to visual stimulation with their own self-image?

Tourette's syndrome is characterised by tics caused in many by premonitory urges; sensations which give patients compulsion to act to relieve discomfort. Habit reversal therapy conditions patients into heightened awareness of premonitory urges and forced counteraction of the tic.

Johns Hopkins docs, researchers explain why you and your family should get vaccinated against the flu

One little stick can save your life. The flu shot remains critically important to fight off the influenza virus, both around the world and in your home, say doctors and researchers at the Johns Hopkins University School of Medicine, who encourage people 6 months of age and older to get vaccinated against this year's influenza virus.

Beijing adopts smoking ban for public places: state media

China's capital on Friday passed a smoking ban for all indoor public places and offices, state media reported, despite the failure of past attempts to limit where the country's 300 million smokers can light up.

Smoking rates halve since 1970s in Britain

The number of smokers in Britain has more than halved in the past four decades, according to the latest figures.

The palaeolithic diet and the unprovable links to our past

We still hear and read a lot about how a diet based on what our Stone Age ancestors ate may be a cure-all for modern ills. But can we really run the clock backwards and find the optimal way to eat? It's a largely impossible dream based on a set of fallacies about our ancestors.

Metals in local groceries may impact kids health

A survey of metal concentrations in 253 food and beverages commonly eaten by Western Australians has turned up mixed results.

Brazil's Amazon region houses latex 'love factory'

Deep in Amazonia, Raimundo Pereira expertly cuts a gash in a rubber tree to collect white sap destined for the nearby factory at Xapuri, the world's only producer of contraceptives made from tropical forest latex.

S. African disease lab on frontline of Ebola fight

South African professor Janusz Paweska hesitates for a moment as he describes his work trip to the heart of the Ebola epidemic in Sierra Leone.

Understanding psychosis and schizophrenia

A report published today by the British Psychological Society's Division of Clinical Psychology challenges received wisdom about the nature of mental illness.

Real-time volume imaging of hearts

A new ultrasound system from Siemens enables doctors to carry out heart examinations through the esophagus for the first time. The system supplies 3D images of the heart as well as additional real-time information about the blood flow throughout the heart. Moreover, these examinations can even be made in patients suffering from ECG irregularities. Surgeons could, for example, use the system to see whether heart valves are closing properly during the corrective procedure. Because a lot of computing power is needed to generate blood flow information in real time, it could previously only be done for small volumes. That's why the new solution, called Acuson SC2000 Prime Edition, has more computing power and an imaging ultrasound scan head that passes through the esophagus to create images of a large part of the heart with a single scan. Siemens presented the new system at this year's congress of the European Society of Cardiology.

Research examines relationship between domestic abuse and football

A report, published today by the Scottish Centre for Crime and Justice Research (SCCJR), highlights a correlation between the occurrence of certain football matches and increased reports of domestic abuse.

Ebola scare boosts business for US company

The Ebola scare has subsided in the United States, at least temporarily, but an Alabama manufacturer is still trying to catch up with a glut of orders for gear to protect against the disease.

Syria hit by flesh-eating maggot disease

Three cases of myiasis have been reported near Damascus, marking the first appearance of the flesh-eating maggot disease in Syria, UN health experts said Friday.
