NewsBiodegradable plastic could replace conventional plastic in coral propagation efforts
Biodegradable plastic cable ties could be used to replace their conventional plastic equivalents in coral propagation as they perform as well and don’t adversely affect coral-associated bacterial communities as they break down.

NewsResearchers pinpoint most likely source of HIV rebound infection
Researchers used genetic sequencing techniques on the nonhuman primate version of HIV to identify that lymph nodes in the abdomen are the main source of rebound infection after the first week of stopping antiretroviral treatment.

NewsProtein may be the ‘glue’ that helps COVID virus stick
A study found that perlecan LG3 – a protein most commonly found in blood vessels and the brain – readily formed a stable bond with the COVID spike protein and perhaps enhanced the virus’ ability to bind with cells.

NewsVirus that infected the first animals now essential for development of the human embryo
All animals have evolved thanks to the fact that certain viruses infected primitive organisms hundreds of millions of years ago. Researchers now describe the role played by these viruses in a process that is absolutely vital for our development.

NewsCyanobacteria blooms intensify in Argentinian reservoirs
Research reveals cyanobacteria blooms have become more intense in Argentinian reservoirs, with positive records of cyanotoxins observed only in the last four years of the study period.

NewsScientists identify window of opportunity for treatment promoting HIV remission
Starting treatment four weeks after infection with HIV promotes long-term control of the virus following the interruption of treatment after two years of antiretroviral therapy.
