Like musicians in an orchestra who have the same musical score but start and finish playing at different intervals, cells with the same genes start and finish transcribing them at different points in the genome. For the first time, researchers at EMBL have described the striking diversity of messenger RNAs (mRNAs) that such start and end variation produces, even from the simple genome of yeast cells. Their findings, published today in Nature, shed new light on the importance of mRNA boundaries in determining the functional potential of genes.

Drinking coffee could decrease the risk of breast cancer recurring in patients taking the widely used drug Tamoxifen, a study at Lund University in Sweden has found. Patients who took the pill, along with two or more cups of coffee daily, reported less than half the rate of cancer recurrence, compared with their non-coffee drinking, Tamoxifen-taking counterparts.

Early, substantive dialogue between parents and their grade-school age children about the ills of tobacco and alcohol use can be more powerful in shaping teen behavior than advertising, marketing or peer pressure, a University of Texas at Arlington marketing researcher has shown.

Exciting new data presented today at the International Liver Congress™ 2013 include results from early in vitro and in vivo studies targeting covalently closed circular DNA (cccDNA), which may form the basis of a cure for chronic hepatitis B virus (HBV) infection.

Melatonin injections delayed symptom onset and reduced mortality in a mouse model of the neurodegenerative condition amyotrophic lateral sclerosis (ALS), or Lou Gehrig's disease, according to a new study by researchers at the University of Pittsburgh School of Medicine. In a report published online ahead of print in the journal Neurobiology of Disease, the team revealed that receptors for melatonin are found in the nerve cells, a finding that could launch novel therapeutic approaches.

Microbubbles decrease the time and acoustic power of ultrasound required to heat and destroy an embedded target, finds research in BioMed Central's open access journal Journal of Therapeutic Ultrasound. If these results can be replicated in the clinic, microbubbles could improve the efficiency of high intensity ultrasound treatment of solid tumors.

The rediscovery of a mystery animal in a museum's underground storeroom proves that a non-native 'big cat' prowled the British countryside at the turn of the last century.

The animal's skeleton and mounted skin was analysed by a multi-disciplinary team of Durham University scientists and fellow researchers at Bristol, Southampton and Aberystwyth universities and found to be a Canadian lynx – a carnivorous predator more than twice the size of a domestic cat.

Antibiotic resistance is a global problem. The World Health Organisation (WHO) estimates that for tuberculosis alone multi-drug resistance accounts for more than 150,000 deaths each year. WHO warns of "a doomsday scenario of a world without antibiotics," in which antibiotic resistance will turn common infections into incurable killers and make routine surgeries a high-risk gamble.

Drinking one (or one extra)* 12oz serving size of sugar-sweetened soft drink a day can be enough to increase the risk of developing type 2 diabetes by 22%, a new study suggests. The research is published inDiabetologia (the journal of the European Association for the Study of Diabetes) and comes from data in the InterAct consortium**. The research is by Dr Dora Romaguera, Dr Petra Wark and Dr Teresa Norat, Imperial College London, UK, and colleagues.

An invisible barrier separates land animals in Australia from those in south-east Asia may also restrict the spillover of animal-borne diseases like avian flu, but researchers have found that fruit bats on either side of this line can carry Nipah virus, a pathogen that causes severe human disease. The findings are published April 24 in the open access journal PLOS ONE by Andrew Breed from the University of Queensland, Australia and colleagues from other institutions.

Deep male voices and high-pitched female voices are perceived as more attractive because listeners gauge the speaker's body size from the frequency of their voice, according to a paper published today in the open access journal PLOS ONE.

Biologists at UC San Diego have identified eight genes never before suspected to play a role in wound healing that are called into action near the areas where wounds occur.

The microbial population in the air of the New York City subway system is nearly identical to that of ambient air on the city streets. This research, published ahead of print in the journal Applied and Environmental Microbiology, establishes an important baseline, should it become necessary to monitor the subway's air for dispersal of potentially dangerous microbes. Also, the combination of new methodologies in the study, including fast collection of aerosols and rapid sequencing technology, provide an efficient means for monitoring which was not previously available.

MINNEAPOLIS – The teenage years may be a key period of vulnerability related to living in the "stroke belt" when it comes to future stroke risk, according to a new study published in the April 24, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology.

Lexington, MA, April 24, 2013 (Embargoed until 2:00 PM US Eastern Time) – T2 Biosystems, a company developing direct detection products enabling superior diagnostics, today announced the publication of research supporting the Company's flagship diagnostic test, T2Candida®, in Science Translational Medicine.
