Capturing an asteroid
|
view preview
According to scientists at The Keck Institute for Space Studies in California, NASA is seriously considering capturing an asteroid to put in a high orbit around the moon. If the idea is implemented, we could be looking at a manned mission to "capture" an asteroid in the 2020s. This idea is thought to tie in with the Obama administration's enthusiasm for sending a manned mission to a near-Earth asteroid. If NASA were able to capture an object and lock it into an orbit around the moon, it could be safely used as a practise mission without the need for astronauts to move beyond the range of a rescue mission. ...

H2O2 vapor used to kill superbugs in hospital
|
view preview
Infection control experts at The Johns Hopkins Hospital have found that a combination of robot-like devices that disperse hydrogen peroxide vapor into the air and then detoxify the disinfecting chemical are highly effective at killing and preventing the spread of multiple-drug-resistant bacteria. Of special note, researchers say, was that enhanced cleaning with the vapor reduced by 80 percent a patient's chances of becoming colonized by a particularly aggressive and hard-to-treat bacterium, vancomycin-resistant enterococci (VRE). ...

Compact Planetary Systems
|
view preview
A new study from the California Institute of Technology (Caltech) estimates that our galaxy contains at least 100 billion planets. The team made their estimate while analysing planets orbiting a star called Kepler-32 - planets that are representative, they say, of the vast majority in the galaxy and thus serve as a perfect case study for understanding how most planets form.

Sun ballet
|
view preview
Sometimes, the Sun itself seems to dance. On just this past New Years Eve, for example, NASAs Sun-orbiting Solar Dynamic Observatory spacecraft imaged an impressive prominence erupting from the Suns surface. The dramatic explosion was captured in ultraviolet light in the above time lapse video covering four hours. Of particular interest is the tangled magnetic field that directs a type of solar ballet for the hot plasma as it falls back to the Sun. The scale of the disintegrating prominence is huge -- the entire Earth would easily fit under the flowing curtain of hot gas. A quiescent prominence typically lasts about a month, and may erupt in a Coronal Mass Ejection expelling hot gas into the Solar System. The energy mechanism that creates a ...

Tractor beam
|
view preview
Scientists at University of St Andrews in Scotland and the Institute of Scientific Instruments (ISI) in the Czech Republic have designed a minute but completely functional tractor beam. Reminiscent of Star Trek, they use a beam of light to draw objects towards the light source on a microscopic level.

Amputations will now be a thing of the past
|
view preview
The very first bionic hand that allows the amputee to actually feel what the hand is touching will be transplanted later this year. According to doctors involved in the surgery the hand will be attached directly to the patient’s nervous system via electrodes clipped onto two of the arm’s main nerves. This will allow the patient to control the hand directly with his thoughts, and receive sensory signals to his brain from the bionic hand. This will be a major breakthrough in prosthetics and could open the door to a new generation of artificial limbs with sensory perception. ...

Shark fin soup

A new estimate suggests 100 million sharks are slaughtered worldwide every year, numbers that are completely unsustainable according to researchers. The majority of the time, the fin is the only part of the body used. The rest is simply thrown away.

New weed that won't get you high sure to bum out stoners
|
view preview
Sad news, stoners. Scientists in Israel have cross-bred a new type of medical marijuana that essentially removes the dopey, high-inducing properties from it — basically, it's pot that won't get you stoned. Researchers with Tikun Olam have meticulously cross-bred their medical pot to eliminate most of the psychoactive THC (tetrahydrocannabinol) properties from it; instead, the cannabis has a high concentration of cannabidiol (CBD), a potent anti-inflammatory. The result is a substance that's great for woozy-free pain relief, terrible for stoners trying to get high. ...

Could dietary salt be the reason for increased incidences of autoimmune diseases?
|
view preview
Researchers at Yale School of Medicine, Harvard Medical School and the Broad Institute have identified a prime suspect in the mystery of an increased incidence of autoimmune diseases in the past few decades—dietary salt. In the paper, researchers showed that salt can induce and worsen pathogenic immune system responses in mice and that the response is regulated by genes already implicated in a variety of autoimmune diseases.

Potential treatment for Down's syndrome?
|
view preview
Down syndrome is caused by a triple copy of chromosome 21, which leads to a number of cognitive and physical delays. Now researchers from the Sanford-Burnham Medical Research Institute in La Jolla, California, have found a protein that restores the some of the cognitive and behavioral disorders found in the disease. Mice who were deficient in the SNX27 protein exhibited similar characteristics to mice with Down syndrome—namely, they had fewer glutamate receptors, which are important for learning and memory, the team reported in Nature Medicine on Sunday (March 24). The researchers also showed that in mice with Down syndrome, the protein is blocked by a molecule encoded on chromosome 21, and produced in excess in Down syndrome mice as a re ...

Super batteries
|
view preview
Imagine a battery the size of the one in your cell phone with enough juice to jump-start a car. It's actually not too far-fetched. Scientists at the University of Illinois have been developing microbatteries. Only a few millimeters long, these batteries may pave the way for electronics to become smaller and thinner, while still providing enough energy to be highly effective. The best part is that it recharges 1000 times faster than current batteries. Good things do come in small packages ...

Ant careers
|
view preview
It turns out that ants are capable of making career moves.Computer tracking of ants shows that colonies have three main occupations: nursing the queen, cleaning, and foraging for food. Younger ants typically stay near the queen, but as they get older, they make the transition to foraging. This transition with regards to age was an exciting discovery, giving more insight into ant behavior.

Radioactive bacteria

view preview
Listeria bacteria has been enlisted by researchers to selectively infect metastatic pancreatic cancer cells and deliver radioisotopes into them. The experimental treatment dramatically decreased the number of metastases (cancers that have spread to other parts of the body) in a mouse model of highly aggressive pancreatic cancer without harming healthy tissue. Mice livers are shown above. The saline control liver on the left presents a large number of metastases compared to the liver on the right which was subject to the radioactive Listeria treatment. ...

Seeds germinate after 2000 years
|
view preview
A Judean date palm plant was planted in 2005 using seeds that were hidden away for 2000 years. While other species of date palms thrive around the world, this particular species was thought to be extinct for 1800 years. Date palms are either male or female, and this one, nicknamed Methuselah, is a male, so it will not produce fruit. However, the plant is alive and well, and is the oldest known seed to successfully germinate.
