A team of neuroscientists at the University of Leicester, UK, in collaboration with researchers from Poland and Japan, has announced a breakthrough in the understanding of the 'brain chemistry' that triggers our response to highly stressful and traumatic events. The discovery of a critical and previously unknown pathway in the brain that is linked to our response to stress is announced today in the journal Nature. The advance offers new hope for targeted treatment, or even prevention, of stress-related psychiatric disorders. About 20% of the population experience some ...

Scientists at Imperial College London and the University of Washington, Seattle, have taken an important step towards developing control measures for mosquitoes that transmit malaria. In today's study, published in Nature, researchers have demonstrated how some genetic changes can be introduced into large laboratory mosquito populations over the span of a few generations by just a small number of modified mosquitoes. In the future this technological breakthrough could help to introduce a genetic change into a mosquito population and prevent it from transmitting the deadly ...

Current UK procedures to screen new immigrants for tuberculosis (TB) fail to detect more than 70 per cent of cases of latent infection, according to a new study published in The Lancet Infectious Diseases. TB is caused by a bacterial infection which is normally asymptomatic, but around one in 10 infections leads to active disease, which attacks the lungs and kills around half of people affected. Today's research showed that better selection of which immigrants to screen with new blood tests can detect over 90 per cent of imported latent TB. These people can be given ...

Infants who have problems with persistent crying, sleeping and/or feeding – known as regulatory problems – are far more likely to become children with significant behavioural problems, reveals research published ahead of print in the journal Archives of Disease in Childhood. Around 20% of all infants show symptoms of excessive crying, sleeping difficulties and/or feeding problems in their first year of life and this can lead to disruption for families and costs for health services. Previous research has suggested these regulatory problems can have an adverse effect ...

Children from homes that experience persistent poverty are more likely to have their cognitive development affected than children in better off homes, reveals research published ahead of print in the Journal of Epidemiology and Community Health. Family instability, however, makes no additional difference to how a child's cognitive abilities have progressed by the age of five, after taking into account family poverty, family demographics (e.g. parental education and mother's age) and early child characteristics, UK researchers found. There is much evidence of the ...

In the past 12 years, four large-scale efficacy trials of HIV vaccines have been conducted in various populations. Results from the most recent trial—the RV144 trial in Thailand, which found a 31 percent reduction in the rate of HIV acquisition among vaccinated heterosexual men and women—have given scientists reason for cautious optimism. Yet building on these findings could take years, given that traditional HIV vaccine clinical trials are lengthy, and that it is still not known which immune system responses a vaccine needs to trigger to protect an individual from HIV ...

Imagine you're driving your own new car--or a rental car--and you need to park in a commercial garage. Maybe you're going to work, visiting a mall or attending an event at a sports stadium, and you're in a rush. Limited and small available spots and concrete pillars make parking a challenge. And it happens that day: you slightly misjudge a corner and you can hear the squeal as you scratch the side of your car--small scratches, but large anticipated repair costs. Now imagine that that you can repair these unsightly scratches yourself--quickly, easily and inexpensively. ...

Research from Perth's Telethon Institute for Child Health Research has found a link between the number of stressful events experienced during pregnancy and increased risk of behavioural problems in children. The study has just been published online in the latest edition of the top international journal Development and Psychopathology. Common stressful events included financial and relationship problems, difficult pregnancy, job loss and issues with other children and major life stressors were events such as a death in the family. Lead author, Registered Psychologist ...

NAIROBI (21 April 2011)— Research released in anticipation of World Malaria Day finds that plants in East Africa with promising antimalarial qualities—ones that have treated malaria symptoms in the region's communities for hundreds of years—are at risk of extinction. Scientists fear that these natural remedial qualities, and thus their potential to become a widespread treatment for malaria, could be lost forever. A new book by researchers at the World Agroforestry Centre (ICRAF) and the Kenya Medical Research Institute (KEMRI), Common Antimalarial Trees and Shrubs of ...

Singapore's first indigenous micro-satellite, X-SAT, lifted off on board India's Polar Satellite Launch Vehicle PSLV-C16 at 10.12am Indian Standard Time (12.42pm, Singapore time) on 20 April 2011. The X-SAT, developed and built by Singapore's Nanyang Technological University (NTU), in collaboration with DSO National Laboratories, was launched from the Satish Dhawan Space Centre at Sriharikota in Andhra Pradesh, India. The wholly made-in-Singapore satellite was one of the two "piggyback" mission satellites loaded on the PSLV-C16 rocket owned by the Indian Space Research ...

The Guide aims to ensure high-quality assisted reproduction treatment as defined by the European Union criteria for good quality medical treatment and the ESHRE position paper on Good clinical treatment in Assisted Reproduction. Although in principle foreign and local patients should be treated the same and with the best possible treatment, there is evidence that this is not always the case. The Guide is based on the core principles in health care: 'equity', 'safety', 'efficiency', 'patient centeredness', 'timeliness' and 'effectiveness'. The principle of equity means ...

In the future, when you walk into a doctor's surgery or hospital, you could be asked not just about your allergies and blood group, but also about your gut type. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, and collaborators in the international MetaHIT consortium, have found that humans have 3 different gut types. The study, published today in Nature, also uncovers microbial genetic markers that are related to traits like age, gender and body-mass index. These bacterial genes could one day be used to help diagnose and predict outcomes ...

ALEPPO, SYRIA (20 April 2011): Researchers meeting at a scientific conference in Aleppo this week reported that aggressive new strains of wheat rust diseases – called stem rust and stripe rust – have decimated up to 40% of farmers' wheat fields in recent harvests. Areas affected are North Africa, the Middle East, Central Asia and the Caucuses, including Syria, Egypt, Yemen, Turkey, Iran, Uzbekistan, Morocco, Ethiopia, and Kenya. “These epidemics increase the price of food and pose a real threat to rural livelihoods and regional food security,” said Mahmoud Solh, Director ...

Local extinction rates of American pikas have increased nearly five-fold in the last 10 years, and the rate at which the climate-sensitive species is moving up mountain slopes has increased 11-fold, since the 20th century, according to a study soon to be published in Global Change Biology. The research strongly suggests that the American pika's distribution throughout the Great Basin is changing at an increasingly rapid rate. The pika (Ochotona princeps), a small, hamster-looking animal sensitive to climate, occurs commonly in rocky talus slopes and lava flows throughout ...

Data from NASA's Cassini spacecraft have revealed that Enceladus, one of Saturn's diminutive moons, is linked to Saturn by powerful electrical currents - beams of electrons that flow back and forth between the planet and moon. The finding is part of a paper published in Nature today. CAPS, one of the instruments on board Cassini which made the electron beam discovery, includes a electron sensor called CAPS-ELS – led by UCL (University College London). Since Cassini's arrival at Saturn in 2004 it has passed 500km-wide Enceladus 14 times, gradually discovering more of ...

The nationwide economic recession has cost tens of thousands their jobs, forced millions into foreclosure and resulted in countless bankruptcy filings. Despite their best efforts, many people are falling behind on mortgage payments due to financial circumstances beyond their control. In an effort to avoid foreclosure, more and more people are seeking loan modifications as a way to lower payments temporarily (or permanently), making them more affordable and making keeping the home a real possibility. Unfortunately, at a time when foreclosures are at a record high, unscrupulous ...

Researchers of Apoptosis and Cancer Group of the Bellvitge Biomedical Research Institute (IDIBELL) have found that a small molecule, Nutlin-3a, an antagonist of MDM2 protein, stimulates the signalling pathway of another protein, p53. By this way, it induces cell death and senescence (loss of proliferative capacity) in brain cancer, a fact that slows its growth. These results open the door for MDM2 agonists as new treatments for glioblastomas. The study has been published at the journal PLoS ONE. Glioblastoma multiforme is the most common brain tumour in adults and the ...

In a multicellular organism, different cells fulfill a range of diversified functions. Often such specialization depends on the delivery of molecular goods to distinct places within a cell. It ensures that particular functions only occur at defined cellular sites. This establishment of intracellular asymmetry in the otherwise fluid environment of the cell cytoplasm requires active transport processes. Messenger RNAs (mRNA) represent an especially important type of freight. They are copies of genetic information stored in the nucleus. In the cytoplasm the information encoded ...

Expectant mothers are familiar with the procedure: the physician examines them with an ultrasound apparatus that displays lifelike images of the fetus on the monitor. The application of this technology has been customary in medicine for years; in materials testing though, it has been used only in relatively rudimentary form to date. Researchers at the Fraunhofer Institute for Non-Destructive Testing IZFP in Saarbrücken have adapted the conventional sonar procedure – a simple ultrasound method – and have succeeded in generating three-dimensional images with the aid of innovative ...

Prosecutors trust that the information they receive from crime labs is correct and accurate. The results from tests run at the lab are used to help build cases against those accused of crimes. When this information is inaccurate it can lead to questions for both past and future cases, and in some instances, lead to innocent people being convicted of crimes they did not commit. The Nassau County crime lab recently became the only police lab in the nation to completely close its doors due to its inability to follow procedures. The lab's troubles started in December 2010. ...

It turns out to be difficult to find out exactly how much a child who cannot yet speak suffers after a surgical operation. Researchers at the University Hospital of La Paz, in Madrid, have validated the 'Llanto' scale, the first, and only, tool in Spanish which measures infant pain rapidly and simply. "The lack of appropriate tools prevents health professionals from knowing if a pre-verbal child who cannot tell us how much a surgical wound hurts, is being treated correctly", explains Francisco Reinoso, lead author of the study and head of the section of Paediatric Anaesthesia ...

BATON ROUGE – On the one year anniversary of the Deepwater Horizon oil spill that took the lives of 11 men and devastated the livelihoods of many residents of coastal Louisiana, it's difficult to put the complicated relationship between people and oil into perspective. While the environmental impacts have thus far not been as pervasive as originally feared, most scientists are in agreement that it is still simply too early to tell. However, dependence upon oil has not lessened over the past year, laying the groundwork for some very significant debates between environmentalists ...

The Northeast has seen three tour bus accidents in less than a month. On March 21, a New Jersey-based PRT tour bus rolled over in New Hampshire, seriously injuring five people. The bus was travelling to Boston from Quebec, carrying 25 Koreans. The driver apparently lost control on a snowy highway. On March 15, a bus headed from Chinatown to Philadelphia crashed on the New Jersey Turnpike in East Brunswick, killing two, the driver and a passenger. The worst accident of the three happened on March 12, with 15 passengers killed when a Worldwide Tours Bus headed to ...

Is the vacuum-packed chicken leg really still fresh and edible? Looks alone do not tell the whole story. And the "best-before" date is no guarantee, either. Scandals involving the sale of rotten meat have added to the uncertainty, and the customer him- or herself may be shortening the shelf life through improper storage. This is an area in which a sensor film developed by the Fraunhofer Research Institution for Modular Solid State Technologies EMFT in Munich can immediately give a green – or rather: yellow light, or warn of spoiled goods. EMFT developed the film in a project ...
