Recent studies indicate that infusing hearts with stem cells taken from bone marrow could improve cardiac function after myocardial infarction - tissue damage that results from a heart attack. But in a recent systematic review, Cochrane Researchers concluded that more clinical trials are needed to assess the effectiveness of stem cell therapies for heart patients, as well as studies to establish how these treatments work.
In a heart attack, blocked arteries can cut off the blood supply to areas of heart tissue. This leads to myocardial infarction - severe tissue damage caused by lack of oxygen, which is transported in the blood.

New research provides support for the use of St. John’s wort extracts in treating major depression - Cochrane Systematic Review backs up previous research that showed the plant extract is effective in treating mild to moderate depressive disorders.
Extracts of the plant Hypericum perforatum, commonly known as St. John’s wort, have long been used in folk medicine to treat depression and sleep disorders. The plant produces a number of different substances that may have anti-depressive properties, but the whole extract is considered to be more effective.

There is no evidence probiotics can relieve the symptoms of eczema and there is evidence that they may occasionally cause infections and gut problems. These findings from The Cochrane Library come at a time when use of probiotics to treat eczema is increasing.
Eczema is an itchy skin condition that affects more than 1 in 20 people at some time in their lives and is especially common in children. Its cause is complex and not well understood, but sufferers do have different bacteria in their guts compared to unaffected people. Consequently, some nutritionists have suggested that eating live gut-dwelling bacteria, such as those found in probiotic yogurts and some infant formulas, could be beneficial.

Scientists at the University of Leicester, where genetic 'fingerprinting' was invented by Professor Sir Alec Jeffreys, say they are developing techniques which may one day allow police to work out someone’s surname from DNA alone.
Research by Turi King has shown that, unsurprisingly, men with the same British surname are highly likely to be genetically linked even in today's multicultural world. The results of her research have implications in the fields of forensics, genealogy, epidemiology and the history of surnames.
On Wednesday 8th October Dr King will present the key findings of her Ph.D. research in which she recruited over two and a half thousand men bearing over 500 different surnames to take part in the study. Carried out in Professor Mark Jobling’s lab, Dr Turi King’s research involved exploring this potential link between surname and Y chromosome type.

Scientists filming in one of the world’s deepest ocean trenches have found groups of highly sociable snailfish swarming over their bait, nearly five miles (7700 metres) beneath the surface of the Pacific Ocean. This is the first time cameras have been sent to this depth.
‘We got some absolutely amazing footage from 7700 metres. More fish than we or anyone in the world would ever have thought possible at these depths,’ says project leader Dr Alan Jamieson of the University of Aberdeen’s Oceanlab, on board the Japanese research ship the Hakuho-Maru.
‘It’s incredible. These videos vastly exceed all our expectations from this research. We thought the deepest fishes would be motionless, solitary, fragile individuals eking out an existence in a food-sparse environment,’ says Professor Monty Priede, director of Oceanlab.

Smell plays an important role in our lives: It influences the way in which we choose fruit and vegetables, perfume, and even a partner. And yet, smell is not just what we smell with our noses, it's also what we taste, explains Prof. Alexander Vainstein, who is heading the team at the Robert H. Smith Faculty of Agriculture, Food and Environment at the Hebrew University of Jerusalem. "Aroma is of major importance for defining the taste of food."
Scent in flowers and plants is used to attract pollinating insects like bees and beetles that pass on the pollen and help in the reproduction and creation of fruit. The intensity of the scent that the flower emanates is influenced by the time of day, depending on weather, age of the flower and the species.
Now Vainstein and others have found a way to genetically enhance the scent of flowers and implant a scent in those that don't have one.

Astronomers studying new images of a nearby galaxy cluster have found evidence that high-speed collisions between large elliptical galaxies may prevent new stars from forming, according to a paper in the November 2008 Astrophysical Journal Letters.
Led by Jeffrey Kenney, professor and chair of astronomy at Yale, the team saw a spectacular complex of warm gas filaments 400,000 light-years-long connecting the elliptical galaxy M86 and the spiral galaxy NGC 4438 in the Virgo galaxy cluster, providing striking evidence for a previously unsuspected high-speed collision between the galaxies. The view was constructed using the wide-field Mosaic imager on the National Science Foundation telescope at Kitt Peak National Observatory near Tucson, Arizona.

Moderate consumption of red wine may decrease the risk of lung cancer in men, according to a report in the October issue of Cancer Epidemiology, Biomarkers & Prevention.
Chun Chao, Ph.D., a research scientist at Kaiser Permanente Department of Research and Evaluation in Pasadena, California, analyzed data collected through the California Men's Health Study, which linked clinical data from California's health system with self-reported data from 84,170 men aged 45 to 69 years. Researchers obtained demographics and lifestyle data from surveys computed between 2000 and 2003, and identified 210 cases of lung cancer.

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics for 2008 with one half to Yoichiro Nambu of the Enrico Fermi Institute, University of Chicago, IL, USA "for the discovery of the mechanism of spontaneous broken symmetry in subatomic physics"
and the other half jointly to;
Makoto Kobayashi, High Energy Accelerator Research Organization (KEK), Tsukuba, Japan and Toshihide Maskawa,Yukawa Institute for Theoretical Physics (YITP), Kyoto University, Japan, "for the discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature".

Your next wireless network could use light instead of radio waves. Researchers funded by a National Science Foundation grant expect to piggyback data communications capabilities on low-power light emitting diodes, or LEDs, to create "Smart Lighting" that would be faster and more secure than current network technology.
This initiative, known as the Smart Lighting Engineering Research Center (http://smartlighting.bu.edu), is part of an $18.5 million, multi-year NSF program awarded to Boston University, Rensselaer Polytechnic Institute and the University of New Mexico to develop the optical communication technology that would make an LED light the equivalent of a WiFi access point. This innovative alternative may one day replace most of today's lighting devices.

When astronauts land on the Moon again they may be able to get a critical commodity there – water.
Bill Kaukler, an Associate Research Professor in the Center for Materials Research at The University of Alabama in Huntsville, has spent the past three years investigating the use of microwaves to replenish water on space missions or as a rocket fuel supply.
“A lot of people think that water doesn’t exist on the Moon,” said Kaukler. “It’s true that not all parts of the Moon have water. Where the Apollo missions landed, there isn’t much water because it is exposed to the sun half of the time. However, in the polar regions, exploratory satellites have found huge amounts of hydrogen, which is evidence that water exists.”

COROT has discovered a massive planet-sized object orbiting its parent star closely, unlike anything ever spotted before. It is so exotic, that scientists are unsure as to whether this oddity is actually a planet or a failed star.
The object, named COROT-exo-3b, is about the size of Jupiter, but packs more than 20 times the mass. It takes only 4 days and 6 hours to orbit its parent star, which is slightly larger than the Sun.
As a planet, COROT-exo-3b would be the most massive and the densest found to date - more than twice as dense as lead. Studying it will help them better understand how to categorise such objects. The mystery is how such a massive object formed so close to its parent.
