But on the remote UK overseas territory of Ascension Island, one of the world's largest green turtle populations is undergoing something of a renaissance.

(PHILADELPHIA) – There is controversy over how best to treat patients after they've undergone surgery for prostate cancer. Does one wait until the cancer comes back or provide men with additional radiation therapy to prevent cancer recurrence? Now, a new study from Thomas Jefferson University shows that a genomic tool can help doctors and patients make a more informed decision.

As fishing and the harvesting of metals, gas and oil have expanded deeper and deeper into the ocean, scientists are drawing attention to the services provided by the deep sea, the world's largest environment. "This is the time to discuss deep-sea stewardship before exploitation is too much farther underway," says lead-author Andrew Thurber. In a review published today in Biogeosciences, a journal of the European Geosciences Union (EGU), Thurber and colleagues summarise what this habitat provides to humans, and emphasise the need to protect it.

EAST LANSING, Mich. --- Teach for America, known for recruiting teachers, is also setting its sights on capturing school board seats across the nation. Surprisingly, however, political candidates from the program aren't just pushing its national education agenda, they're advancing local issues as well, according to a new study.

Achalasia is a rare disease – it affects 1 in 100,000 people – characterized by a loss of nerve cells in the esophageal wall. While its cause remains unknown, a new study by a team of researchers at KU Leuven in Belgium, the University of Bonn in Germany and other European institutions confirms for the first time that achalasia is autoimmune in origin. The study, published on 6 July in Nature Genetics, is an important step towards unraveling the mysterious disease.

Epidemiological studies have repeatedly shown that death rates rise in association with extremely hot weather. The heat wave in Western Europe in the summer of 2003, for example, resulted in about 22,000 extra deaths. A team of researchers led by Dr. Alex-andra Schneider at the Institute of Epidemiology II at the Helmholtz Zentrum München examined the impact of extreme temperatures on the number of deaths caused by cardiovascular disease in three Bavarian cities and included both high and low temperatures in the study.

A new stem-cell discovery might one day lead to a more streamlined process for obtaining stem cells, which in turn could be used in the development of replacement tissue for failing body parts, according to UC San Francisco scientists who reported the findings in the current edition of Cell.

The work builds on a strategy that involves reprogramming adult cells back to an embryonic state in which they again have the potential to become any type of cell.

Scientists investigating the herpes virus have been surprised to find an ongoing conflict in the cells of sufferers, even when the virus is apparently dormant.

Herpes Simplex Type 1 is a virus that causes cold sores. It remains in the body's nervous system indefinitely after infection. Around 80 per cent of Australians carry the virus, although it is usually in a dormant state.

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.
