Drug dealers found with bank notes contaminated with unusually high levels of drugs are now less likely to get away with their crimes. The research finds that geographical location has absolutely no influence on the distribution of drug contamination on bank notes. Paper money is almost always tainted with some drug residue. Evidence presented at court shows how banknotes seized from a suspect may...

Unless Greater London Authority (GLA) takes radical steps, one of which could be the removal of all cars from both inner and outer London, it will not meet its goals for reducing carbon dioxide emissions, according to a new report. Calculations show that a car-free inner London scenario equates to a 49 percent reduction in emissions.

Most of us have never heard of immune infertility, yet it prevents many prospective parents from conceiving. This reproductive disorder affects both men and women, causing their immune systems to wage war on sperm. A recent discovery may help pinpoint what molecules assist the immune system in attacking sperm.

Researchers have found that patients suffering from the metabolic syndrome -- a cluster of conditions that increases the risk for heart disease, stroke and diabetes -- also have a propensity to develop highly acidic urine, which increases the risk of developing kidney stones.

Scientists have developed a new method for controlling the self-assembly of nanometer and micrometer-sized particles. The method, based on designed DNA shells that coat a particle's surface, can be used to manipulate the structure -- and therefore the properties and potential uses -- of numerous materials that may be of interest to industry.

They say that the way to a man's heart is through his stomach and the same could be said for female chimpanzees. Researchers studying wild chimps in West Africa have discovered that males pinch desirable fruits from local farms and orchards as a means of attracting female mates.

Although pictures can be appreciated in any language, digital image searches are often lost in translation. A new multilingual search tool, PanImages, makes the universal appeal of pictures available to all. A new multilingual search tool makes the universal appeal of pictures available to all. PanImages allows people to search for images on the Web using hundreds of languages.

Online social networks tend to be far larger than their real-life counterparts, but online users say they have about the same number of close friends as the real-life average person. The advent of online social networking sites like Myspace and Facebook is changing the average number of friends people have, with some users befriending literally thousands of others, according to researchers.

Scientists describe a new technique that can detect how proteins undergo changes inside a cell. The technique promises to improve our understanding of how proteins inside cells work and identify how some proteins are not modified properly in common diseases such as cancer and cardiovascular diseases.

The fossil record seems to indicate that the diversity of marine creatures increased and decreased over hundreds of millions of years in step with predator-prey encounters. For decades, there has been a debate between paleontologists, biologists, and ecologists on the role of ecological interactions, such as predation, in the long term patterns of animal evolution.

Individuals who take vitamin D supplements appear to have a lower risk of death from any cause over an average follow-up time of six years, according to a meta-analysis of 18 previously published studies. Individuals who took vitamin D had a 7 percent lower risk of death than those who did not.

A new technique which enables us to identify faces more accurately could make security systems more reliable. Humans are very good at identifying faces we know. However, researchers said, we are much less accomplished when the face is unknown to us. This is almost always the case with the faces captured by CCTV cameras or used to check at a passport barrier.

Psychological factors can make people more likely to suffer physical illness, but cognitive behavioural therapy can help sufferers manage their condition. "People often pigeonhole diseases as being biological or psychological, but in fact they're often a complex mixture of both," according to a researcher. She and her colleagues studied 1000 people who contracted either glandular fever or food...

The drug tadalafil appears to improve erectile function in men with spinal cord injuries, according to a new article. Between 10.4 and 83 individuals per million worldwide experience spinal cord injuries every year, according to background information in the article. Only 25 percent of men with spinal cord injuries are able to have erections that are adequate for having intercourse.

With equal access to medical care and medication, Hispanic men and women have as good or greater chance as non-Hispanics of controlling their high blood pressure, researchers reported in Hypertension: Journal of the American Heart Association.

While sweet sorghum and sugarcane are close relatives, the researchers have shown that the two species have different ways of moving and storing sugar. Tracer sucrose is inserted into growing plants, using a system similar to an IV. Once the sucrose is inside the plants, the researchers can track the movement and distribution.

Researchers provide new details about the inner workings of a parasitic worm that causes a tropical disease called schistosomiasis, which leads to itchy skin, fever, chills, muscle aches, and liver disease that, in some cases, can be fatal. The new results may help design drugs or vaccines against the disease. Schistosomiasis, a disease affecting up to 200 million people in Asia, Africa, and South...

Scientists may have solved a discrepancy between the number of extremely small, faint galaxies predicted to exist near the Milky Way and the number actually observed. In an attempt to resolve the "Missing Dwarf Galaxy" problem, two astronomers used the W. M. Keck Observatory in Hawaii to study a population of the darkest, most lightweight galaxies known, each containing 99% dark matter. The...

Health professionals are regularly confronted by men's complaints that condoms do not fit, or that they are uncomfortable. Correct condom use is critical for preventing unwanted pregnancies and the spread of sexually transmissible infections, yet a new study found that study participants who reported problems with the fit and feel of condoms were also among those who reported the highest rates of...

A fitness expert encourages her personal training clients to break their more ambiguous goals of say, feeling better or dropping a few dress sizes, into smaller goals that can be achieved in three to four weeks. She discourages weight-oriented goals because weight loss is a long-term process and everyone loses weight at different rates. Instead, she wants to know how her clients feel. She is a big...

Significant sexual problems often are an unexpected -- and unwelcome -- side effect of the treatment of early-stage cervical and endometrial cancer for many women following hysterectomy. A targeted therapeutic approach involving mindfulness training has been found to improve desire, orgasm, arousal and other aspects of sexual satisfaction in just three one-hour sessions.

A new turbulence detection system, now being tested, is successfully alerting pilots to patches of rough air as they fly through clouds. The system is designed to better protect passengers from injuries caused by turbulence while reducing flight delays and lowering aviation costs.

In the cerebral cortex, the brain's powerful central processing unit responsible for higher functions, specialized subdivisions known as areas are laid out like a map, but little is known about the genetic forces that shape the geography of our brains.

Researchers have discovered a mechanism that plays a critical role in the multiple myeloma cell cycle and survival. This new research may result in identification of a new therapeutic target for treating multiple myeloma.
