How bacterial cells divide in two is not fully understood. Physicists of Ludwig-Maximilians-Universitaet (LMU) in Munich now show that, at high concentrations, a crucial protein can assemble into ring-shaped filaments that constrict the cell, giving rise to two daughter cells.

An experimental study carried out by Ludwig-Maximilians-Universitaet (LMU) in Munich media researchers has found that readers rate texts generated by algorithms more credible than texts written by real journalists.

A class of 150 US 7th graders has helped select a name for a newly discovered plant, which amazes with its fruits that appear to be bleeding once they are cut open. Bucknell University biology professor Chris Martine and life science teacher Bradley Catherman challenged the students to come up with ideas for what to call the new Australian species last spring.

How species genetically adapt to their environment is a central question related to the evolution of biodiversity. In a new study scientists at Uppsala University and their colleagues report that whole genome sequencing of Atlantic and Baltic herring revealed hundreds of loci underlying adaptation to the brackish Baltic Sea or timing of reproduction. The study is published today in eLife.

RNA polymerase II (Pol II), a key enzyme in our gene expression, is responsible for transcribing DNA into messenger RNA. Errors in transcription can cause deleterious effect upon repeated translation of erroneous mRNA into protein. Transcription infidelity may result in aging and human diseases such as cancer. During transcription, Pol II can detect the mis-incorporated RNA and backtrack to correct errors to ensure that each messenger RNA created will match with template DNA. However, it remains largely a mystery how Pol II controls the fidelity of gene transcription.

"The results for tolerability, safety, and the immune response to the vaccine candidate are very promising," explains Prof Marylyn Addo. The antibodies which developed against the virus were still detectable after six months. Addo is convinced, "With this, a single vaccine could provide lasting protection against Ebola." The infectious disease specialist, who works for the German Center for Infection Research at the University Medical Center Hamburg Eppendorf (UKE) in Hamburg, led the trial in Hamburg.

The number of new HIV infections occurring annually in the United States decreased by an estimated 11 percent from 2010 to 2015, while the HIV transmission rate decreased by an estimated 17 percent during the same time period, according to new research from the Johns Hopkins Bloomberg School of Public Health and the University of Pennsylvania.

With Tottenham's dreams of Premier League glory shattered before their very eyes by a 2-2 draw at Stamford Bridge, University of Leicester students research whether it is possible to really cry a river.

Musicians Arthur Hamilton, Justin Timberlake and unsympathetic people across the world have encouraged others to 'cry me a river', a put-down phrase to make light of people's problems.

Researchers from the University of Birmingham have found that extended rest intervals between sets of weight-lifting could help with muscle growth.

The findings, published in Experimental Physiology, go against the conventional belief that favours shorter periods of rest. The study highlights that short rest intervals may actually impair the processes that control muscle growth.

Physicists from Ludwig-Maximilians-Universitaet (LMU) in Munich have developed a way to distinguish the random motions of particles in non-living molecular systems from the motility of active living matter. The method affords new insights into fundamental biological processes.

PHILADELPHIA--The number of new HIV infections and the transmission rate in the United States dropped by 11 and 17 percent, respectively, between 2010 and 2015, but fell short of the goals put forth by President Obama's U.S.

HILLSBOROUGH, NJ (May 3, 2016) - Over the last 30+ years, veterinary professionals' understanding of clinical feline hyperthyroidism (FHT) has evolved tremendously. Initially FHT cats were referred to a specialist and now primary practitioners routinely manage these cases. The disease reportedly affects from 1.5-11.4% of cats around the world and is the most common endocrine disease of cats over 10 years of age in the US.

Altitude training is a popular method for athletes wanting to improve their physical performance. At high altitudes oxygen levels are blood cells. This enables an enhanced performance at lower altitudes because more oxygen can be delivered to the muscles.

Many companies now offer altitude training in specialist chambers (often referred to as normobaric training) as an alternative to lowered so our bodies compensate by increasing the number of red traveling to a high altitude country (hypobaric training), which is costly in terms of both time and money.

Current estimates of the number of cheetahs in the wild are 'guesswork', say the authors of a new study which finds that the population in the cheetah stronghold of Maasai Mara, Kenya, is lower than previously thought.

In the early 1900s it was believed that around 100,000 cheetahs roamed the Earth. The most recent estimate by the International Union for Conservation of Nature (IUCN) puts the figure at 6,600 - mainly in eastern and southern Africa - amid fears that the fastest land mammal is racing to extinction.

Powerful head and neck retractions of vertebrate carcasses, including dinosaur fossils, have puzzled researchers as to whether they occurred just before an animal's death in agony, or after. Now experiments performed in the wild on large ostrich chick cadavers show that they occur post-mortem.

The experiments show that the timing of soft tissue decay is critical, and that muscle destruction or loss of tone must occur before ligament destruction. This would allow for the release of stored energy in the ligament and result in vertebral retraction.
