'Life on Mars' lander aims for risky touch down on red planet

By Maria Sheahan FRANKFURT (Reuters) - The search for life on Mars may take a giant leap on Wednesday when a space lander is due to touch down on the red planet in Europe's first attempt to land a craft there since the Beagle 2's "heroic failure" more than a decade ago. The disc-shaped 577-kg (1,272 lb) Schiaparelli lander, which will test technologies for a rover due to follow in 2020, is expected to enter Mars's atmosphere at a speed of nearly 21,000 km (13,049 miles) per hour at 1442 GMT. The lander is named for Giovanni Schiaparelli, the Italian astronomer who in 1877 began mapping the topography of Mars, extending study of what are now known as the planet's canals, a mistranslation of the Italian word canali, or channels.

Birthplace of Rosetta Probe's Comet Pinned Down

The comet that Europe's Rosetta spacecraft orbited for more than two years was probably born in the realm of icy bodies beyond Neptune, a new study suggests. New analyses of the orbit of Comet 67P/Churyumov-Gerasimenko — on which Rosetta intentionally crash-landed on Sept. 30, ending the probe's historic mission — trace the object's origins back to the Kuiper Belt, whose most famous denizen is Pluto. "These results come from computations of the comet's orbit from the present to the past, which is computationally difficult due to the chaosity of the orbit caused by close encounters with Jupiter," Mattia Galiazzo, a postdoctoral fellow in the Department of Physics and Astronomy at Western University in Ontario, Canada, said in a statement.

Left at the 1st Neuron: Project Will Map Every Human Cell

A new international initiative is creating an atlas that will chart every single cell in the human body, encompassing all of the tissues within Homo sapiens, scientists announced last week at a meeting in London. The revolutionary project, called the Human Cell Atlas, will help biologists and doctors understand, diagnose and treat diseases with the help of high-resolution images of healthy and atypical cells from every structure in the body. The initiative was formally announced at an international meeting convened by the Broad Institute of the Massachusetts Institute of Technology and Harvard University, Wellcome Trust Sanger Institute, and Wellcome Trust on Oct. 13 and 14.

Mothers' Obesity Linked with Biologically 'Older' Newborns

Babies whose mothers are obese may be biologically "older" than babies whose mothers are a normal weight, a new study from Belgium suggests. Researchers analyzed information from 743 mothers ages 17 to 44, and their newborn babies, using samples of umbilical cord blood obtained from each newborn immediately after delivery. Telomeres naturally shorten as people age, but they don't shorten at the same rate in every person.

Model Contracts Eye Infection from 'Dirty' Makeup Brush

An Australian model who contracted an eye infection from a shared makeup brush is now speaking out about the importance of good hygiene when using makeup or getting your makeup done. The model, Anthea Page, posted on Instagram that she contracted a staph infection of the eye after getting her makeup done at a fashion show, where the makeup artists did not properly clean the brushes. "I have just been on a fashion show job for the past 4 days and unfortunately, even though I had observed unhygienic practises and confronted the qualified artists (who I will not name), I still ended up taking home a nasty eye infection from fashion weekend," Page wrote on Instagram.

Don't Fret Step Counts: These Fitness Tracker Measures Are More Important

Your fitness tracker may nag you to reach "10,000 steps a day," but if you can't meet this goal, don't give up hope — a new study finds that taking fewer steps may still bring health benefits, especially if you walk at a brisk pace. More research would be needed to see how changing step count influences health, the researchers said.

The New Science of Willpower: Can Self-Control Really Get Used Up?

Does willpower have a limit? Indeed, a whole line of research, based on a seminal study published in 1998, suggested that not only is human willpower a depletable resource, but it's also drawn from a singular source in the brain. Many psychologists now think this phenomenon, dubbed "ego depletion," doesn't exist at all.

Maggots under microscope for superbug-killing secretions

By Matthew Stock Maggots could help tackle the looming crisis of antibacterial resistance, according to researchers from Swansea University, who found that certain molecules in the secretions of green bottle fly maggots are highly effective at killing some species of bacteria. "We knew, anecdotally and from past studies, that maggots were working to kill bacterial infections in wounds," explained Dr Yamni Nigam, lead researcher of the Swansea Maggot Research group.
