Climate change and coral reefs: Coral species has developed the 'skills' to cope with rising temperatures Posted: 27 Feb 2010 02:00 PM PST Marine reserves are increasingly important for species that are being forced by climate change to move to a new home, adapt to new conditions or die. Biologists have now compared the relative benefits of large and small protected areas in perpetuating populations. Interestingly they have also found a coral species that has developed the "skills" to cope with rising temperatures.

Increasing neurogenesis might prevent drug addiction and relapse Posted: 27 Feb 2010 02:00 PM PST Researchers hope they have begun paving a new pathway in the fight against drug dependence. Their hypothesis -- that increasing the normally occurring process of making nerve cells might prevent addiction -- is based on a rodent study demonstrating that blocking new growth of specific brain nerve cells increases vulnerability for cocaine addiction and relapse.

Flower power may reduce resistance to breast cancer drug tamoxifen Posted: 27 Feb 2010 02:00 PM PST Combining tamoxifen, the world's most prescribed breast cancer agent, with a compound found in the flowering plant feverfew may prevent initial or future resistance to the drug, say researchers. The finding provides new insight into the biological roots of that resistance, and also tests a novel way to get around it.

Computer simulation of protein malfunction related to Alzheimer's disease Posted: 27 Feb 2010 02:00 PM PST Researchers created a computer modeling of the structural malfunctioning of the ApoE4 protein when it enters into contact with the amyloid beta molecule, the main cause of Alzheimer's disease. The research supports experimental evidence that links ApoE4 with this pathology and opens up new exploration possibilities in understanding and fighting against the disease.

Malicious software: Hiding the honeypots Posted: 27 Feb 2010 02:00 PM PST Armies of networked computers that have been compromised by malicious software are commonly known as Botnets. Such Botnets are usually used to carry out fraudulent and criminal activity on the Internet. Now US computer scientists reveal that the honeypot trap designed to protect computers from Botnets are now vulnerable to attack because of advances in Botnet malware.

Others may know us better than we know ourselves, study finds Posted: 27 Feb 2010 02:00 PM PST Humans have long been advised to "know thyself," but new research suggests we may not know ourselves as well as we think we do. While individuals may be more accurate at assessing their own neurotic traits, such as anxiety, it seems friends, and even strangers, are often better barometers of traits such as intelligence, creativity and extroversion.

Threat to monkey numbers from forest decline Posted: 27 Feb 2010 08:00 AM PST Monkey populations in threatened forests are far more sensitive to damage to their habitat than previously thought. Numbers closely related to the type of habitat found between forest fragments, rather than the distance that separates them.

Gene signature may improve colon cancer treatment Posted: 27 Feb 2010 08:00 AM PST A gene signature, first identified in mouse colon cancer cells, may help identify patients at risk of colon cancer recurrence, according to a recent study. The findings could help personalize treatments for colon cancer -- the second leading cause of cancer-related deaths in the United States -- by identifying patients most likely to benefit from chemotherapy.

Lack of morning light keeping teenagers up at night Posted: 27 Feb 2010 08:00 AM PST The first field study on the impact of light on teenagers' sleeping habits finds that insufficient daily morning light exposure contributes to teenagers not getting enough sleep.

A primer on migraine headaches Posted: 27 Feb 2010 08:00 AM PST Migraine headache affects many people and a number of different preventative strategies should be considered, according to a new article.

Intelligent energy management for the home Posted: 27 Feb 2010 08:00 AM PST In order to save energy, consumers need to be able to obtain up-to-date information at any time about the energy consumption of their appliances, and be able to control them while away from home. Scientists have developed two new applications that help consumers manage their power use.

Many adult diseases sprout in poverty, molecular sociologist says Posted: 27 Feb 2010 08:00 AM PST The roots of many adult diseases sprout in poverty and other burdens on the socially disadvantaged. A self-described molecular sociologist recently talked about the effects such environmental stressors have on the brain and in turn other organ systems.

Can math and science help solve crimes? Scientists work with Los Angeles police to identify and analyze crime 'hotspots' Posted: 27 Feb 2010 02:00 AM PST Scientists working with the Los Angeles Police Department to analyze crime patterns report that criminal "hotspots" come in at least two different types -- one of which can be suppressed by police. They believe their findings apply to cities worldwide.

Gestational diabetes: Blood sugar levels once considered normal are not safe for baby, mother Posted: 27 Feb 2010 02:00 AM PST Two to three times more pregnant women may soon be diagnosed and treated for gestational diabetes, based on new measurements for determining risky blood sugar levels for the mother and her unborn baby, according to a new study. Blood sugar levels that were once considered in the normal range are now seen as causing a sharp increase in the occurrence of overweight babies, early deliveries, cesarean section deliveries and potentially life-threatening preeclampsia.

Presence of snails points to forest recovery Posted: 27 Feb 2010 02:00 AM PST Researchers have studied the changes in the make-up of animal populations following forest fires, and have concluded that malacological fauna are a good indicator of forest recovery. The conclusions of this study will help to ensure that post-fire forestry operations that do not harm these species of mollusks, which are sensitive to microclimatic conditions of the soil and vegetation structure.

Mechanism for Frank-Ter Haar syndrome discovered Posted: 27 Feb 2010 02:00 AM PST Scientists have discovered that TKS4, a protein implicated in cancer metastasis, also plays a significant role in Frank-Ter Haar syndrome, a rare fatal disorder.

Hastening progress of 3D cinema and TV Posted: 27 Feb 2010 02:00 AM PST This is the year in which 3D cinema and 3D TV will make the breakthrough. At CeBIT in Hannover, German researchers are presenting technologies and standards that are hastening the progress.

Stress raises risk of mental decline in older diabetics, study shows Posted: 27 Feb 2010 02:00 AM PST Stress raises the risk of memory loss and cognitive decline among older people with diabetes, research suggests. Researchers have studied more than 900 men and women aged between 60 and 75 with type-2 diabetes, which tends to be common after the age of 40. They found that brain function slowed in participants with higher levels of the stress hormone cortisol.

New 'alien invader' star clusters found in Milky Way Posted: 26 Feb 2010 05:00 PM PST As many as one quarter of the star clusters in our Milky Way -- many more than previously thought -- are "invaders" from other galaxies, according to a new study.

New cancer treatment gives hope to lymphoma and leukemia patients Posted: 26 Feb 2010 05:00 PM PST Cancer researchers have high hopes for a new therapy for patients with certain types of lymphoma and leukemia.

Good parenting triumphs over prenatal stress Posted: 26 Feb 2010 05:00 PM PST A mother's nurture may provide powerful protection against risks her baby faces in the womb, according to a new article. The research shows that fetuses exposed to high levels of stress hormone -- shown to be a harbinger for babies' poor cognitive development -- can escape this fate if their mothers provide them sensitive care during infancy and toddler-hood.

The pig and its pancreas: A unique model for a common disease Posted: 26 Feb 2010 05:00 PM PST The incidence of diabetes is rising worldwide. Using genetic engineering techniques in pigs, scientists at in Germany have created a new model of this metabolic disorder, which recapitulates many features of the disease, and promises to contribute significantly to improvements in diagnosis and therapy.

Scientists unlock key enzyme using newly created 'cool' method Posted: 26 Feb 2010 05:00 PM PST Scientists -- using a new cooling method they created -- have uncovered the inner workings of a key iron-containing enzyme, a discovery that could help researchers develop new medicines or understand how enzymes repair DNA. Taurine/alpha-ketoglutarate dioxygenase, known as TauD, is a bacterial enzyme that is important in metabolism. Enzymes in this family repair DNA, sense oxygen and help produce antibiotics.

Hypnosis can help control pain among women with metastatic breast cancer Posted: 26 Feb 2010 05:00 PM PST Hypnosis can help alleviate the pain and suffering experienced by women being treated for breast cancer, according to a new study.

Smoking significantly increases risk of aneurysm in people with certain genes Posted: 26 Feb 2010 02:00 PM PST Researchers have confirmed three gene changes that raise the risk that a blood vessel in the brain will weaken and balloon out (aneurysm), creating a life-threatening chance of rupture. Smoking, the biggest risk factor for brain aneurysm, is five times more dangerous in people with these gene variations. However, a second study on the same population notes that most people with aneurysm die of cancer or heart problems.

Scanning for skin cancer: Infrared system looks for deadly melanoma Posted: 26 Feb 2010 02:00 PM PST Researchers have developed a noninvasive infrared scanning system to help doctors determine whether pigmented skin growths are benign moles or melanoma, a lethal form of cancer.

New study casts doubt on link between chronic fatigue syndrome and human retrovirus XMRV Posted: 26 Feb 2010 02:00 PM PST A new study casts doubt on recent claims that a human retrovirus known as XMRV is linked to chronic fatigue syndrome or ME (myalgic encephalitis).

Why symptoms of schizophrenia emerge in young adulthood Posted: 26 Feb 2010 02:00 PM PST In reports of two new studies, researchers say they have identified the mechanisms rooted in two anatomical brain abnormalities that may explain the onset of schizophrenia and the reason symptoms don't develop until young adulthood. Both types of anatomical glitches are influenced by a gene known as DISC1, whose mutant form was first identified in a Scottish family with a strong history of schizophrenia and related mental disorders.

Large Iceberg breaks off Antarctica's Mertz Glacier Posted: 26 Feb 2010 11:00 AM PST Scientists have discovered the calving of a large iceberg from Antarctica's Mertz Glacier. The iceberg -- 78 kilometres long with a surface area of roughly 2,500 square kilometres, about the size of Luxembourg -- broke off after being rammed by another iceberg, 97 kilometres long. The future position of the two giant icebergs will likely affect local ocean circulation, experts predict.
