Scientists believe some tropical species may be able to evolve and adapt to the effects of climate change.
The new findings published in the journal, Proceedings of the Royal Society B, suggests some sensitive rainforest-restricted species may survive climate change and avoid extinction. But only if the change is not too abrupt and dramatically beyond the conditions that a species currently experiences.
Giving parents access to a dedicated website on the measles, mumps and rubella (MMR) vaccine is the most cost-effective way to increase uptake, say experts.
The study published in the British Journal of General Practice, recommends that a dedicated website be developed as part of guidelines on the MMR vaccine.
Denmark attracted international attention in 2012 when archaeological excavations revealed the bones of an entire army, whose warriors had been thrown into the bogs near the Alken Enge wetlands in East Jutland after losing a major engagement in the era around the birth of Christ. Work has continued in the area since then and archaeologists and experts from Aarhus University, Skanderborg Museum and Moesgaard Museum have now made sensational new findings.
Aarhus University researchers have developed an easier method to create DNA–protein conjugates. The method can potentially strengthen the work involved in diagnosing diseases.
LOS ANGELES (July 28, 2014) – A new technique for repairing the most common cardiac birth defect in newborns, commonly referred to as "a hole in the heart," has been used successfully to mend the condition in six premature infants without subjecting the tiny patients to open-heart surgery.
New research from scientists at the University of Kent has shown for the first time how the structures inside cells are regulated – a breakthrough that could have a major impact on cancer therapy development.
A team from Kent's School of Biosciences uncovered the mechanism whereby the physical properties of the internal structures within cells – known as actin filaments – are 'fine-tuned' to undertake different functions.
Many different types of cell, including sperm, bacteria and algae, propel themselves using whip-like appendages known as flagella. These protrusions, about one-hundredth of a millimetre long, function like tiny oars, helping cells move through fluid. Similar, shorter structures called cilia are found on the surfaces of many cells, where they perform roles such as moving liquids over the cell.
About 100 drugs already approved by the U.S. Food and Drug Administration (FDA) for other purposes can also prevent the growth of certain bacterial pathogens inside human cells, including those that cause Legionnaires' disease, brucellosis, and Mediterranean spotted fever. The findings, published in mBio®, the online open-access journal of the American Society for Microbiology, demonstrate a new way of identifying non-antibiotic drugs that could one day help curb bacterial infections.
Two beneficial variants of a gene controlling red blood cell development have spread from Africa into nearly all human populations across the globe, according to a new study led by King's College London. The international team studied the genomes of world populations to look for the origin of changes in a key regulator gene which stimulate fetal haemoglobin production into adulthood. Fetal haemoglobin is normally found in fetuses and infants, but some patients with inherited blood disorders who are able to keep making it as adults experience milder symptoms of their condition.
Cancer cells are gluttons. We have long known that they monopolize large amounts of sugar. More recently, it became clear that some tumor cells are also characterized by a series of features such as mobility or unlikeliness to join in an ordered set. Researchers are calling this behavior "mesenchymal," and they suspect it promotes metastasis.
Deerfield, Ill. (July 28, 2014) – An international research team today reports the first-ever clinical trial demonstrating controlled malaria infection in an African nation in the modern era. The study, published online in the American Journal of Tropical Medicine and Hygiene (AJTMH) represents a significant milestone in the search for new malaria drugs and vaccines.
Early initiation of menopausal hormone therapy (MHT) improves some markers of cardiovascular disease (CVD) but does not affect the progression of atherosclerosis, according to a study being published in Annals of Internal Medicine. CVD is the leading cause of death in women and incidence increases after menopause. Research suggests that cardiovascular benefits of MHT may be limited to women who begin treatment at a younger age, closer to menopause, or both.
An international team of researchers led by the University of Arizona has sequenced the complete genome of African rice.
The genetic information will enhance scientists' and agriculturalists' understanding of the growing patterns of African rice, as well as enable the development of new rice varieties that are better able to cope with increasing environmental stressors to help solve global hunger challenges.
Bottom Line: An electronic screening tool that starts with a single question to assess the frequency of substance misuse appears to be an easy way to screen teenagers who visited a physician for routine medical care.

Running for only a few minutes a day or at slow speeds may significantly reduce a person's risk of death from cardiovascular disease compared to someone who does not run, according to a study published today in the Journal of the American College of Cardiology.
Exercise is well-established as way to prevent heart disease and it is component of an overall healthy life, but it is unclear whether there are health benefits below the level of 75 minutes per week of vigorous-intensity activity, such as running, recommended by the U.S. government and World Health Organization.
