Scientists have discovered that bacteria can reshape their DNA to survive dehydration. The research shows that bacterial DNA can change from the regular double helix to the more compact A-DNA form, when faced with hostile conditions such as dehydration.
While it was known that a specific birch pollen protein causes the immune system to overreact, the exact reason why many people are allergic to birch pollen had not yet been fully clarified. Now, scientists at the Vetmeduni Vienna have discovered what makes the protein an allergen.
Young men who use cannabis may be putting their fertility at risk by inadvertently affecting the size and shape of their sperm, according to recently published research.
Nutritionists regularly suggest breakfast be eaten each morning for health benefits, including weight loss. But new research shows that, when comparing regularly consuming with regularly skipping breakfast, weight loss was not influenced.
A new report offers the strongest evidence yet that a mysterious Middle East virus spreads from camels to people. Researchers studied the illness of a 44-year-old camel owner in Saudi Arabia, who died in November of Middle East respiratory syndrome, or MERS.
Limiting saturated fat could help people whose genetic make-up increases their chance of being obese, according to a new study. The findings could be useful in identifying people who are predisposed to obesity and could ultimately lead to personalized dietary recommendations.
A test that counts the number of locations in tumor specimens where tumor cells may invade blood vessels predicted the risk of distant spread, or metastasis, for the most common type of breast cancer.
Researchers are reporting promising treatment milestones for patients with deadly skin and lung cancers who are being treated with an experimental drug called MK-3475.
One of the biggest challenges for medical researchers studying the effectiveness of stem cell therapies is that transplants or grafts of cells are often rejected by the hosts. Now, researchers have shown that a new line of genetically modified pigs will host transplanted cells without the risk of rejection.
Christofer Toumazou believes he can change the world with his “one chip, one bug – one chip, one drug,” slogan. Nominated for the European Patent Office’s 2014 European Inventor award, he holds a patent for the technology behind a microchip that can analyze DNA within 30 minutes and without a laboratory.
A Purdue University-led research team has figured out how to disable a part of the SARS virus responsible for hiding it from the immune system; a critical step in developing a vaccine against the deadly disease. The findings also have potential applications in the creation of vaccines against other coronaviruses, including MERS.
Biomedical engineering students have designed a lightweight, easy-to-conceal shirt-like garment to deliver life-saving shocks to patients experiencing serious heart problems. The students say their design improves upon a wearable defibrillator system that is already in use.
By analyzing the blood of almost 100 treated and untreated HIV-infected volunteers, a team of scientists has identified previously unknown characteristics of B cells in the context of HIV infection.
Researchers at King’s College London have discovered how a molecular ‘scaffold’ which allows key parts of cells to interact, comes apart in dementia and motor neuron disease (such as ALS), revealing a potential new target for drug discovery.
Researchers have found a new type of neuron in the adult brain that is capable of telling stem cells to make more new neurons. Though the experiments are in their early stages, the finding opens the tantalizing possibility that the brain may be able to repair itself from within.
Children who later develop autism are exposed to elevated levels of steroid hormones (for example testosterone, progesterone and cortisol) in the womb, according to scientists. The finding may help explain why autism is more common in males than females. However, the researchers caution it should not be used to screen for the condition.
Women age 55 or younger may fare worse than their male counterparts after having a heart attack, according to new research presented at the American Heart Association’s Quality of Care and Outcomes Research Scientific Sessions 2014. Researchers studied records and interviews of 3,501 people (67 percent women) who had heart attacks in the United States and Spain in 2008-12.
Britain's fertility regulator says controversial techniques to create embryos from the DNA of three people "do not appear to be unsafe" even though no one has ever received the treatment, according to a new report. Read more...
Baylor College of Medicine scientists defined a previously unrecognized genetic cause for two types of birth defects found in newborn boys. Cryptorchidism and hypospadias are among the most common birth defects but the causes are usually unknown.
Studying mice, researchers have found a way to prevent nonalcoholic fatty liver disease, the most common cause of chronic liver disease worldwide. Blocking a path that delivers dietary fructose to the liver is what prevented mice from developing the condition.
Many people with cystic fibrosis develop diabetes. The reasons for this have been largely unknown, but now researchers have identified a molecular mechanism that contributes to the raised diabetes risk.
Twenty years after the hormone leptin was found to regulate metabolism, appetite, and weight through brain cells called neurons, researchers have found that the hormone also acts on other types of cells to control appetite.
The gap between stem cell research and regenerative medicine just became a lot narrower, thanks to a new technique that coaxes stem cells, with potential to become any tissue type, to take the first step to specialization. It is the first time this critical step has been demonstrated in a laboratory.
Traumatic bone injuries are often so severe that the body can’t effectively repair the damage on its own. To aid the recovery, clinicians inject patients with proteins called growth factors. The treatment is costly, requiring large amounts of growth factors. The growth factors also disperse, creating unwanted bone formation. A new developing technology could provide more efficient delivery of the bone regenerating growth factors.
Research by the University of Liverpool has found that eating prunes as part of a weight control diet can improve weight loss. Consumption of dried fruit is not readily recommended during weight loss despite evidence it enhances feelings of fullness. However, a study of 100 overweight and obese low fiber consumers tested whether eating prunes as part of a weight loss diet helped or hindered weight control over a 12-week period.
