With national attention focused on the avian flu threat, other infections that could be transmitted from animals to people are also coming under scrutiny. People with work exposure to pigs, such as farmers, veterinarians and meat processing workers, are at heightened risk of contracting swine influenza, according to a study in the Jan. 1 issue of Clinical Infectious Diseases, now available online.
Pigs’ physical makeup allows them to contract—and to spread—influenza viruses to and from other species, such as humans and birds. Due to their susceptibility to influenza virus infections from other species, pigs can also serve as “mixing vessel hosts” that can produce new influenza virus strains that could pose a risk to human health.
In Iowa, the state with the highest swine production, researchers examined farmers, veterinarians, meat processing workers and a control group of people who had no occupational contact with pigs. They discovered that, of the four groups, farmers were most likely to be seropositive—that is, to have antibodies in their blood against swine influenza, indicating previous infection with the virus. Veterinarians also had increased odds of seropositivity. Meat processing workers had elevated antibody levels as well, though the odds were not as high, perhaps due to the workers’ limited exposure to live pigs.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
