New spectral eye video database SPEED revolutionizes eye-tracking

Science Daily - Thu, 22/06/2017 - 12:28pm
Techniques to acquire spectral data have been static for a long time - until now. Exciting and novel spectral video technologies are emerging, allowing us to extract increasingly dynamic knowledge from light. Using a spectral video device in eye-tracking, computational spectral imaging and eye-tracking researchers have created a novel - first of its kind - combined spectral video/spectral image database: the SPectral Eye vidEo Database, SPEED.

Pathogen that causes sleeping sickness: Promising new target

Science Daily - Thu, 22/06/2017 - 12:27pm
The life-threatening African trypanosomiasis, also called sleeping sickness, is caused by protozoa of the species Trypanosoma brucei. A team of researchers has studied the pathogens and reported exciting news: The trypanosomes have a so far unknown enzyme which does not exist in humans and other vertebrates. This makes it a promising target for therapy.

Radioactive elements in Cassiopeia A suggest a neutrino-driven explosion

Science Daily - Thu, 22/06/2017 - 12:27pm
Stars exploding as supernovae are the main sources of heavy chemical elements in the Universe. In particular, radioactive atomic nuclei are synthesized in the hot, innermost regions during the explosion and can thus serve as probes of the unobservable physical processes that initiate the blast. Using elaborate computer simulations, a team of researchers was able to explain the recently measured spatial distributions of radioactive titanium and nickel in Cassiopeia A, a roughly 340 year old gas remnant of a nearby supernova.

Secondhand smoke exposure among nonsmoking adult cancer survivors has declined

Science Daily - Thu, 22/06/2017 - 12:25pm
From 1999/2000 to 2011/2012, exposure to secondhand smoke among nonsmoking adult cancer survivors declined from 39.6 percent to 15.7 percent, but rates of exposure were higher among those with a history of a smoking-related cancer and those living below the federal poverty level compared with those with other types of cancer and those with the highest incomes, respectively.

Studies of US Lassa fever patient offer clues about immune response, viral persistence

Science Daily - Thu, 22/06/2017 - 12:25pm
Researchers were able to closely study a Lassa fever patient's immune response over time after he was evacuated to the US for treatment. An experimental drug, favipiravir, was used in treating the US patient and an additional patient infected with Lassa virus in Germany. The drug appeared to have few serious side effects, but its efficacy is unknown. Individual patient reports cannot be generalized to broader population, but findings suggest promising areas for future research.

Biofilms: The eradication has begun

Science Daily - Thu, 22/06/2017 - 12:25pm
Biofilms are slimy, glue-like membranes that are produced by microbes in order to colonize surfaces. They protect microbes from the body's immune system and increase their resistance to antibiotics. Biofilms represent one of the biggest threats to patients in hospital settings. But there is good news: scientists have developed a novel enzyme technology that prevents the formation of biofilms and can also break them down.
