Schoolboy survives direct hit by meteorite travelling at 30,000mph

The odds of it happening are astronomical, but not impossible, as one schoolboy found out when he was struck by a passing meteorite.

The rock flew down from space at speeds of 30,000mph, and grazed past 14-year-old Gerrit Blank as he made his way to school.

The meteorite continued on before ending its billion-year intergalactic journey on the pavement, leaving a smoking, foot-wide crater.

Gerrit was left with a scar on his hand, making him one of only a handful of people to have been struck directly by a meteorite.

The student, from Essen, Germany, said: ‘At first I just saw a large ball of light, and then I suddenly felt a pain in my hand.

‘Then a split second after that there was an enormous bang like a crash of thunder.’
The rock would originally have been a lot larger, but would have burned up in the atmosphere as it fell to Earth. Most ‘shooting stars’ burn up completely before they hit the ground.

Experts are now examining the pea-sized meteorite to discover its origins. Most meteorites date back to the formation of the solar system 4.55billion years ago.

The odds of being hit by a meteorite are said to be one in a 100million. There is not a confirmed fatality from a direct hit before, although there are many reported cases of animals being killed by an impact.

One woman in Alabama, America, was injured as she lay asleep in bed in 1954. The 4kg meteorite struck her after smashing through her roof.

A monk is said to have been killed by a meteorite in Milan in 1650 and two sailors in Sweden were reportedly killed by one while sailing in 1674.

Scientists Expect To Create Life In Next 10 years

First cell of synthetic life can only be seen under a microscope.

WASHINGTON – Around the world, a handful of scientists are trying to create life from scratch and they’re getting closer.

Experts expect an announcement within three to 10 years from someone in the now little-known field of “wet artificial life.”

“It’s going to be a big deal and everybody’s going to know about it,” said Mark Bedau, chief operating officer of ProtoLife of Venice, Italy, one of those in the race. “We’re talking about a technology that could change our world in pretty fundamental ways — in fact, in ways that are impossible to predict.”


Step Made Toward Invisible Electronics

From Live Science:

Researchers have made an advance toward a long-sought goal of building “invisible electronics” and transparent displays.

The work could eventually lead to better heads-up displays for pilots or even windshield displays and cars, as well as electronic paper that could deliver all the contents of a magazine or a newspaper on one, ever-changing, portable and perhaps even disposable sheet. Another goal: wearable electronic clothing displays.

The scientists, led by Chongwu Zhou and colleagues at UCLA developed tiny, transparent electronic circuits they say are more powerful than similar devices developed in recent years.

The work was detailed in the Jan. 27 issue of ACS Nano, a monthly journal.

In the new study, Chongwu Zhou and colleagues point out that although scientists have previously developed nano-sized transparent circuits, previous versions are limited to a handful of materials that are transparent semiconductors.


Tips to Taking Holiday Pictures

During the holidays, we attempt to capture every meaningful moment with a few clicks of the button. When it is all said and done, you may only find a handful of photographs that you are happy with. Some of the pictures looked washed out or blurry, while others are lack of any real emotions. Here
are a few tips to help each of your holiday photographs leap off the paper.

Choose the Right Setting

Before you begin taking holiday pictures, you want to make sure t check on the ISO setting on your digital camera. When the ISO setting is set to a higher speed, it will translate into a faster shutter speed and reduce the chance for blurry images. This simple photography tip is especially important if you are trying to take photographs of children because their motor is normally on high throughout the day. If you are not sure how to change your ISO setting, refer to the cameras owner manual.

Reduce the Red Eye

Thanks to the advancements in camera technology, the ability to reduce red eye from your holiday photographs is easy as pie. The problem is even the best amateur photographers forget to set the red eye reduction prior to snapping away. If you still manage to find glimpses of red eye sneaking into your photographs, you can find a variety of computer software, like Photoshop and that will be able to remove the small annoyance.

Bringing Stem Cells to War: Meet the Blood Pharmers

From Popular Mechanics:

New research from DARPA could open the door to on-demand blood-cell manufacturing on battlefields and in hospitals. All medics need is a machine that uses a nanofiber that mimics bone marrow to turn a handful of stem cells into gallons of blood. Who needs blood donations when you have blood pharming?

Fresher blood is better than stale: It carries more oxygen and, when transfused into patients, speeds recovery. Military medics are all too familiar with this problem in the field, where donated blood may take two or more weeks to reach soldiers who need it immediately. But medical researchers—also known as blood pharmers—are working on manufacturing the red stuff on the spot.
