The insurance industry, the world's largest business with $4.6 trillion in revenues, is making larger efforts to manage climate change-related risks, according to a new study published today in the journal Science. "Weather- and climate-related insurance losses today average $50 billion a year. These losses have more than doubled each decade since the 1980s, adjusted for inflation," says the study's author Evan Mills, a scientist in Lawrence Berkeley National Laboratory (Berkeley Lab)'s Environmental Energy Technologies Division. "Insurers have become quite adept at quantifying ...

BOSTON—Scientists at Dana-Farber Cancer Institute have discovered a molecular switch that enables advanced prostate cancers to spread without stimulation by male hormones, which normally are needed to spur the cancer's growth. They say the finding could lead to a new treatment for prostate cancers that are no longer controlled by hormone-blocking drugs. The researchers report in the Dec. 14 issue of Science that the molecular switch occurs in a protein, EZH2, which is increased in these tumors, termed castration-resistant prostate cancers (CRPC). EZH2 is part of a ...

Montreal, December 13, 2012 – From Gran Turismo to WWE Smackdown, sports-based video games represent a wide variety of pursuits. When it comes to the people who actually play those games, however, little is known. How do sports video game players fit their games into a larger sports-related context? How does their video game play inform their media usage and general sports fandom? That's what Concordia University communications professor Mia Consalvo sought to discover when she embarked on a large-scale study of video game players, the results of which were recently published ...

CHICAGO -- Northwestern Medicine researchers have discovered a "two-faced" group of cells at work in human colon cancer, with opposing functions that can suppress or promote tumor growth. These cells are a subset of T-regulatory (Treg) cells, known to suppress immune responses in healthy individuals In this previously unknown Treg subset, the presence of the protein RORγt has been shown to differentiate between cancer-protecting and cancer-promoting properties. The Northwestern team, led by Khashayarsha Khazaie, research associate professor at the Robert H. ...

ARGONNE, Ill. – For the first time, scientists witnessed the details of the full, ultrafast process of liquid droplets evolving into a bubble when they strike a surface. Their research determined that surface wetness affects the bubble's fate. This research could one day help eliminate bubbles formed during spray coating, metal casting and ink-jet printing. It also could impact studies on fuel efficiency and engine life by understanding the splashing caused by fuel hitting engine walls. "How liquid coalesces into a drop or breaks up into a splash when hitting something ...

Prostate cancer patients receiving the costly treatment known as proton radiotherapy experienced minimal relief from side effects such as incontinence and erectile dysfunction, compared to patients undergoing a standard radiation treatment called intensity modulated radiotherapy (IMRT), Yale School of Medicine researchers report in the Journal of the National Cancer Institute. Standard treatments for men with prostate cancer, such as radical prostatectomy and IMRT, are known for causing adverse side effects such as incontinence and erectile dysfunction. Proponents of ...

New research by a University of Alberta archeologist may lead to a rethinking of how, when and from where our ancestors left Africa. U of A researcher and anthropology chair Pamela Willoughby's explorations in the Iringa region of southern Tanzania yielded fossils and other evidence that records the beginnings of our own species, Homo sapiens. Her research, recently published in the journal Quaternary International, may be key to answering questions about early human occupation and the migration out of Africa about 60,000 to 50,000 years ago, which led to modern humans ...

The plague-causing bacteria Yersinia pestis evades detection and establishes a stronghold without setting off the body's early alarms. New discoveries reported this week help explain how the stealthy agent of Black Death avoids tripping a self-destruct mechanism inside germ-destroying cells. The authors of the study, appearing in the Dec. 13 issue of Cell Host & Microbe, are Dr. Christopher N. LaRock of the University of Washington Department of Microbiology and Dr. Brad Cookson, UW professor of microbiology and laboratory medicine. Normally, certain defender cells ...

A venomous primate with two tongues would seem safe from the pet trade, but the big-eyed, teddy-bear face of the slow loris (Nycticebus sp.) has made them a target for illegal pet poachers throughout the animal's range in southeastern Asia and nearby islands. A University of Missouri doctoral student and her colleagues recently identified three new species of slow loris. The primates had originally been grouped with another species. Dividing the species into four distinct classes means the risk of extinction is greater than previously believed for the animals but could ...

CHAMPAIGN, Ill. — On the road to smaller, high-performance electronics, University of Illinois researchers have smoothed one speed bump by shrinking a key, yet notoriously large element of integrated circuits. Three-dimensional rolled-up inductors have a footprint more than 100 times smaller without sacrificing performance. The researchers published their new design paradigm in the journal Nano Letters.

HOUSTON – (Dec. 13, 2012) – Since Edison's first bulb, heat has been a mostly undesirable byproduct of light. Now researchers at Rice University are turning light into heat at the point of need, on the nanoscale, to trigger biochemical reactions remotely on demand. The method created by the Rice labs of Michael Wong, Ramon Gonzalez and Naomi Halas and reported today in the American Chemical Society journal ACS Nano makes use of materials derived from unique microbes – thermophiles – that thrive at high temperatures but shut down at room temperature. The Rice project ...

CHAMPAIGN, lll. — Every time a human or bacterial cell divides it first must copy its DNA. Specialized proteins unzip the intertwined DNA strands while others follow and build new strands, using the originals as templates. Whenever these proteins encounter a break – and there are many – they stop and retreat, allowing a new cast of molecular players to enter the scene. Scientists have long sought to understand how one of these players, a repair protein known as RecA in bacterial cells, helps broken DNA find a way to bridge the gap. They knew that RecA guided a broken ...

TORONTO, Dec. 13, 2012—There's new evidence about the benefits of marriage. Women who are married suffer less partner abuse, substance abuse or post-partum depression around the time of pregnancy than women who are cohabitating or do not have a partner, a new study has found. Unmarried women who lived with their partners for less than two years were more likely to experience at least one of the three problems. However, these problems became less frequent the longer the couple lived together. The problems were most common among women who were separated or divorced, especially ...
