Enzyme USP15 Limits Ovarian Cancer Cells And Boosts Chemotherapy
Ovarian cancer is devastating, five-year survival rate under 30%, when detected after it has spread. New basic research may improve that.

Just before dawn on Oct. 7, 2008, an SUV-sized asteroid entered Earth's atmosphere and exploded harmlessly over the Nubian Desert of northern Sudan. Scientists expected the asteroid, called 2008 TC3, had blown to dust in the resulting high-altitude fireball. What happened next excited the scientific community. Peter Jenniskens, a meteor astronomer with the SETI Institute in Mountain View, Calif., who works at NASA's Ames Research Center in Moffett Field, Calif., joined Muawia Shaddad of the University of Khartoum in Sudan to search for possible extraterrestrial remnants from the asteroid.
It wouldn't seem logical today that big predators are at the greatest risk for extinction, but they are, and a group of researchers sees a number of similarities between extinctions of 65 million years ago and today.Studies of modern fishes demonstrate that large body size is linked to large prey size and low rates of population growth, while fast-closing jaws appear to be adaptations for capturing agile, evasive prey—in other words, other fishes. The fossil record provides some remarkable evidence supporting these estimates of function: fossil fishes with preserved stomach contents that record their last meals.
Autism is a complex developmental disability that affects a person's ability to communicate and interact with others. It usually appears during the first three years of life. Autism is called a "spectrum disorder" since it affects individuals differently and to varying degrees. It is estimated that one in every 150 American children has some degree of autism.Scientists at Albert Einstein College of Medicine of Yeshiva University have proposed a new hypothesis about autism, suggesting that the brains of people with autism are structurally normal but dysregulated - meaning symptoms of the disorder might be reversible.
Researchers at Albert Einstein College of Medicine of Yeshiva University say they have discovered a process that controls the amount of fat that cells store for use as a back-up energy source. Disruption of this process allows cellular fat to accumulate — a key factor in age-related metabolic diseases such as obesity and type 2 diabetes.
Butterflies seem able to both attract mates and ward off predators using different sides of their wings, according to new research in the journal Proceedings of the Royal Society B: Biological Sciences. Trying to find the balance between these two crucial behaviors is one of nature’s oldest dilemmas, according to Jeffrey Oliver, a postdoctoral associate in Yale’s Department of Ecology and Evolutionary Biology and lead author on the study.
6 out of every 10 university students, regardless their field of study, get anxious when it comes to mathematics, according to a research work carried out at the University of Granada. There are significant differences between men and women in this sense, as men suffer less anxiety when it comes to deal with mathematical tasks (47% of men against 62% of women).
Is today's academic and corporate culture stifling science's risk-takers and stopping disruptive, revolutionary science from coming to the fore? Writing in Physics World, Mark Buchanan looks at those who have shifted scientific paradigms and asks what we can do to make sure that those who have the potential to change our outlook on the world also have the opportunity to do so.
A groundbreaking new loudspeaker, less than 0.25mm thick, has been developed by University of Warwick engineers, it's flat, flexible, could be hung on a wall like a picture, and its particular method of sound generation could make public announcements in places like passenger terminals clearer, crisper, and easier to hear. All speakers work by converting an electric signal into sound. Usually, the signal is used to generate a varying magnetic field, which in turn vibrates a mechanical cone, so producing the sound. Lightweight and inexpensive to manufacture, the new 'Flat, Flexible Loudspeaker' (FFL) speakers are slim and flexible: they could be concealed inside ceiling tiles or car interiors, or printed with a design and hung on the wall like a picture.
Sure, things are tough all over. Heck, Linda Evangelista recently stated she now would get out of bed for less than $10,000 a day(1).
Can't wait for the next Star Trek movie? Okay, this doesn't have Zoe Saldana but it's still pretty terrific - the first movie ever of carbon atoms moving along the edge of a graphene crystal. Given that graphene, single-layered sheets of carbon atoms arranged like chicken wire, may hold the key to the future of the electronics industry, the audience for this new science movie might also reach blockbuster proportions.
It's not just American cars that are hurting the environment, researchers in California and Colorado have set their sights on ... rocket launches?
Future ozone losses from unregulated rocket launches will eventually exceed ozone losses due to chlorofluorocarbons, or CFCs, which stimulated the 1987 Montreal Protocol banning ozone-depleting chemicals, said Martin Ross, chief study author from The Aerospace Corporation in Los Angeles. The study, which includes the University of Colorado at Boulder and Embry-Riddle Aeronautical University, provides a market analysis for estimating future ozone layer depletion based on the expected growth of the space industry and known impacts of rocket launches.
Here's another reason to hate leftovers. A research study in the Journal of Leukocyte Biology sheds light on one cause of arthritis: bacteria. In the study, scientists from the United States and The Netherlands show that a specific gene called NOD2 triggers arthritis or makes it worse when leftover remnants of bacteria cell walls, called muramyl dipeptide or MDP, are present. This discovery offers an important first step toward new treatments to prevent or lessen the symptoms of inflammatory arthritis.
