TPU scientists proposed using special diffraction gratings with gold plates instead of microlenses to accelerate the generation of images from nanoscopes without losing any magnification power. The advanced nanoscopes are promising for biological research to study living viruses and the insides of cells.
The most severe pandemic in recent history, killing some 50 million people worldwide, the Spanish influenza, may have emerged up to two years earlier than previously believed. And, according to a new and influential study, its early manifestation was ignored at the time as a 'minor infection.'
New research from Brigham Young University professors finds there is a better way to help increase support for vaccinations: Expose people to the pain and suffering caused by vaccine-preventable diseases instead of trying to combat people with vaccine facts.
Researchers at McMaster University have invented a stable, affordable way to store fragile vaccines for weeks at a time at temperatures up to 40C, opening the way for life-saving anti-viral vaccines to reach remote and impoverished regions of the world.
In Mexicali, Mexico, an uncontrolled epidemic of Rocky Mountain spotted fever, one of the deadliest tickborne diseases in the Americas, has affected more than 1,000 people since 2008. A binational team of researchers led by the University of California, Davis, has conducted the first comprehensive study to examine risk factors for the disease in Mexicali. Researchers examined dogs, ticks, and surveyed households in 200 neighborhoods.
Scientists from the University of Adelaide's Research Centre for Infectious Diseases have developed a single vaccination approach to simultaneously combat influenza and pneumococcal infections, the world's most deadly respiratory diseases.
In a recent study published in BBA -- General Subjects, Kanazawa university researchers have used high-speed microscopy to investigate native structure and conformational dynamics of hemagglutinin in influenza A.
The Zika virus outbreak in Latin America has affected over 60 million people up to now. The infection can have potentially fatal consequences for pregnant women and their unborn children: many children have subsequently been born with malformations of the head (microcephaly). A particularly high incidence of these Zika-associated malformations exists in northeastern Brazil. DZIF scientists from Charité -- Universitätsmedizin Berlin tried to find out the reasons for this regional cluster and discovered a surprising protective factor.
Antiviral antibodies produced by survivors of Ebola infection continue to evolve and improve after recovery, according to a study of immune responses in four people who received care at Emory University Hospital in 2014. High levels of neutralizing antibodies- thought to be key to protecting someone against deadly infection -- didn't appear in patients' blood until months after they left the hospital.
Host-cell enzymes called PARP12 and PARP14 are important for inhibiting mutant forms of a coronavirus, according to a study published May 16 in the open-access journal PLOS Pathogens by Stanley Perlman of the University of Iowa, Anthony Fehr of the University of Kansas, and colleagues.
