Chromosome buffers hold key to better melanoma understanding

Buffers that guard against damage to the ends of chromosomes could hold the key to a better understanding of malignant melanoma – the deadliest form of skin cancer – according to new research from the University of Leeds.

The study has uncovered an important new genetic risk factor for melanoma.

It is well known that pigmentation and mole count are the strongest indicators of those most at risk of developing melanoma. For example, paler people should take more care in the sun, as they burn more easily.

Shorebird's beak inspires UT Arlington research on water collection

A UT Arlington engineering professor and his doctoral student have designed a device based on a shorebird's beak that can accumulate water collected from fog and dew.

The device could provide water in drought-stricken areas of the world or deserts around the globe.

Scripps Research Institute chemists modify antibiotic to vanquish resistant bacteria

LA JOLLA, CA—September 17, 2014—Scientists at The Scripps Research Institute (TSRI) have devised a new antibiotic based on vancomycin that is powerfully effective against vancomycin-resistant strains of MRSA and other disease-causing bacteria.

The new vancomycin analog appears to have not one but two distinct mechanisms of anti-microbial action, against which bacteria probably cannot evolve resistance quickly.

Targeted radiation, drug therapy combo less toxic for recurrent head, neck cancers

SAN FRANCISCO, Sept. 17, 2014 – Patients with a recurrence of head and neck cancer who have previously received radiation treatment can be treated more quickly, safely and with fewer side effects with high doses of targeted radiation known as Stereotactic Body Radiation Therapy (SBRT) in combination with a drug that also carefully targets cancerous tumors. These findings from a UPMC CancerCenter study were presented today at the American Society of Radiation Oncology (ASTRO) annual meeting in San Francisco.

Nemo's epic journey to find a new home

New research has found clownfish larvae can swim up to 400 kilometres in search of a home, which makes them better able to cope with environmental change.

Clownfish spend their entire adult lives under the protection of their host anemone but as babies they must wander the open ocean, says study co-author, Dr Hugo Harrison from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at James Cook University.

Blood test could identify when cancer treatment has become detrimental

Some treatments for prostate cancer, while initially effective at controlling the disease, not only stop working over time but actually start driving tumour growth, a major new study shows.

Researchers identified the emergence of drug-resistant cancer cells by testing repeated blood samples from patients with advanced prostate cancer.

They set out a new 'treatment paradigm' – the constant monitoring of patients using a blood test for signs that therapy is becoming counter-productive.

Expedition finds Nemo can travel great distances to connect populations

Clownfish spend their entire lives nestling in the protective tentacles of host anemones, but new research shows that as babies they sometimes travel hundreds of kilometres across the open ocean. Although the process of long-distance dispersal by reef fish has been predicted, this is the first time that the high level exchange of offspring between distant populations has been observed.

Contributions on Fauna Europaea: Data papers as innovative model on expert involvement

Fauna Europaea started in 2000 as an EC-FP5 four-year project, delivering its first release in 2004.

A link between Jacobsen syndrome and autism

SAN DIEGO, Calif. (Sept. 17, 2014)— A rare genetic disorder known as Jacobsen syndrome has been linked with autism, according to a recent joint investigation by researchers at San Diego State University and the University of California, San Diego. In addition to suggesting better treatment options for people with Jacobsen syndrome, the finding also offers more clues into the genetic underpinnings of autism.

Nature's designs inspire research into new light-based technologies

BELLINGHAM, Washington, USA -- "Nature has developed, very cleverly, some lessons on how to create the features that we desire in optical design," said Joseph Shaw, director of the Optical Technology Center at Montana State University. "As we explore surfaces and structures at the nanoscale, we'll discover them."

Persian Gulf states have new role to play in Israeli-Palestinian conflict resolution

HOUSTON – (Sept. 17, 2014) – The shifting regional geopolitics of the Middle East have created new opportunities for the Persian Gulf states to engage in Arab-Israeli conflict resolution, according to a new paper from Rice University's Baker Institute for Public Policy.

New branch added to European family tree

The setting: Europe, about 7,500 years ago.

Agriculture was sweeping in from the Near East, bringing early farmers into contact with hunter-gatherers who had already been living in Europe for tens of thousands of years.

Genetic and archaeological research in the last 10 years has revealed that almost all present-day Europeans descend from the mixing of these two ancient populations. But it turns out that's not the full story.

Natural born killers: Chimpanzee violence is an evolutionary strategy

ANN ARBOR—Man's nearest relatives kill each other in order to eliminate rivals and gain better access to territory, mates, food or other resources—not because human activities have made them more aggressive.

That is the conclusion of an international analysis of lethal aggression among different groups of chimpanzees in Africa studied over five decades. The research appears in the current issue of Nature.

Nature of war: Chimpanzees inherently violent according to study

(Chicago) -- Of all of the world's species, humans and chimpanzees are some of the only to engage in coordinated attacks on other members of their same species. Jane Goodall was among the first to introduce the occurrence of lethal inter-community killings and since then primatologists and anthropologists have long debated the concept of warfare in this genus. Research theories have pointed to increased gains and benefits of killing off competitors and opening up increased access to key resources such as food or mates.

Modern Europeans descended from three groups of ancestors

New studies of ancient DNA are shifting scientists' ideas of how groups of people migrated across the globe and interacted with one another thousands of years ago. By comparing nine ancient genomes to those of modern humans, Howard Hughes Medical Institute (HHMI) scientists have shown that previously unrecognized groups contributed to the genetic mix now present in most modern-day Europeans.
