Parasitic butterfly larvae may mimic ants' acoustic signals to aid in the infiltration of their host colonies, according to results published April 9, 2014, in the open access journal PLOS ONE by Marco Sala from University of Turin, Italy, and colleagues.

A National Institutes of Health (NIH) study reports that a rare genetic disease, while depleting patients of infection-fighting antibodies, may actually protect them from certain severe or recurrent viral infections. Researchers found that HIV and influenza viruses replicate in the cells of people with congenital disorder of glycosylation type IIb (CDG-IIb) at a much lower rate than in healthy donor cells, creating fewer and less infectious viruses. The study, published in The New England Journal of Medicine, was led by Sergio Rosenzweig, M.D., Ph.D., director of the Primary Immune Deficiency (PID) Clinic at the NIH's National Institute of Allergy and Infectious Diseases (NIAID).

U.C. Santa Barbara physicist Tarun Grover says he has definitive mathematical evidence for supersymmetry in a condensed matter system. Sought after in the realm of subatomic particles by physicists for several decades, supersymmetry describes a unique relationship between particles.

The fundamental constituents of matter — electrons, quarks and their relatives — are fermions. The particles associated with fundamental forces are called bosons. Several decades ago, physicists hypothesized that every type of particle in the Standard Model of particle physics, a theory that captures the dynamics of known subatomic particles, has one or more superpartners — other types of particles that share many of the same properties but differ in a crucial way.

The team has so far identified 14 vulnerable HTML5-based apps from three types of mobile systems, including Android, iOS and Blackberry. Developers of those vulnerable apps have been informed and in an effort to give them time to fix the problem, researchers have decided not to disclose the names of the vulnerable apps.

"Imagine you're at the airport and you want to find the free Wi-Fi. When you scan, your phone is going to display the Wi-Fi access points. That could be an easy channel for a hacker to inject malicious worm code into your smartphone," Du says. "Once the worm takes control, it can duplicate itself, and send copies to your friends via SMS messages, multimedia file sharing, and other methods."

The legacy of European science and biotechnology is good - Europeans say that health research is important - but modern acceptance of science remains lacking. However, a new survey by Institut National de la Santé et de la Recherche Médicale - Inserm - shows that Europeans may discard their recent stance against science and embrace progress again. It will take a culture of science literacy on par with the United States and a culture that shakes off government control, according to the results.

On the less glamorous side of space exploration, there's the more practical problem of waste — in particular, what to do with astronaut pee. But rather than ejecting it into space, scientists are developing a new technique that can turn this waste burden into a boon by converting it into fuel and much-needed drinking water.
