New protein discovery could change biotech forever

The quest started with trying to make better yogurt.

Bacteria that uses a tiny molecular machine to kill attacking viruses could change the way that scientists edit the DNA of plants, animals and fungi, revolutionizing genetic engineering. The protein, called Cas9, is quite simply a way to more accurately cut a piece of DNA.

Many people are not aware of how often we are exposed to bacteria and viruses.

A report examining attitudes to cleanliness and general hygiene has been released to coincide with Global Handwashing Day.  One in ten people have admitted avoiding public transport and trips to the movies because of worries over cleanliness and general hygiene levels.

Major breakthrough on how viruses infect plants

plant virus 34988

CSIRO plant scientists have shed light on a problem that has puzzled researchers since the first virus was discovered in 1892 — how exactly do they cause disease?

In a major breakthrough that helps us better understand how viruses cause diseases in plants — and potentially in animals and humans — Dr Ming-Bo Wang and Neil Smith of CSIRO Plant Industry have revealed a genetic mechanism that enables viral organisms to infect hosts and cause diseases…

Scientists Identify Antivirus System in Host Cells

Scientists have discovered a new anti-virus system

Viruses have led scientists at Washington University School of Medicine in St. Louis to the discovery of a security system in host cells. Viruses that cause disease in animals beat the security system millennia ago.

Eating almonds boosts immune system response to viruses.

Eating almonds can help the body to fight off viral infections such as the common cold and flu, according to new research.  A new study has revealed that naturally occurring chemicals found in the skin of the nut boost the immune system’s response to such infections.

Unexpected Viral ‘Fossils’ Found in Vertebrate Genomes

Colorized negative stained transmission electron micrograph (TEM) depicts a number of Marburg virus virions.

Over millions of years, retroviruses, which insert their genetic material into the host genome as part of their replication, have left behind bits of their genetic material in vertebrate genomes. In a recent study, published July 29 in the open-access journal PLoS Pathogens, a team of researchers have now found that human and other vertebrate genomes also contain many ancient sequences from Ebola/Marburgviruses and Bornaviruses — two deadly virus families.
