Stressed koalas are facing a deadly epidemic

Researchers have shown that stress and retrovirus levels are tightly linked to disease in koalas. High KoRV loads make koalas more vulnerable to chlamydia, worsening epidemics in stressed populations. Protecting habitats, careful breeding, and antiviral trials are now being pursued to give koalas a fighting chance at survival.

Deformed wing virus genetic diversity in US honey bees complicates search for remedies

Deformed Wing Virus (DWV), one of the leading causes of honey bee colony losses, is much more genetically diverse in the United States than previously thought. The diverse lineages of this virus are all equally bad for bees, and they make it more complicated to develop antiviral therapeutics, which could be the basis for developing a vaccine for the virus.

Spotting cutting-edge topics in scientific research using keyword analysis

Researchers have conducted a quantitative keyword analysis of 30 million articles in the life sciences over a nearly fifty-year period (1970-2017) and found that 75% of total emerging keywords, at 1-year prior to becoming identified as emerging, co-appeared with other emerging keywords in the same article.

Four new strains of human adenovirus

Large-scale study to identify human adenovirus genotypes in Singapore leads to discovery of four new adenovirus strains and increase in strains linked to severe diseases. Researchers suggest use of antiviral therapies and adenovirus vaccines, and routine monitoring of adenovirus strains.

Strategies of a honey bee virus

The Israeli Acute Paralysis Virus is a pathogen that affects honey bees and has been linked to Colony Collapse Disorder, a key factor in decimating the bee population. Researchers have now analyzed in detail how the virus hijacks the cellular protein production machinery and misuses it for its own purposes.

New portable DNA sequencer quickly and accurately diagnoses wheat viruses

A group of scientists have developed a new technology that makes it possible to rapidly identify viruses in wheat fields with a significantly higher accuracy. They collected four wheat samples from western Kansas and used a new harmonica-sized DNA sequencer and a computer program to quickly detect three different viruses in the samples. Furthermore, their results suggested that the samples contained a new virus strain.
