HIV researchers solve key puzzle after 20 years of trying (w/ Video)
Researchers have made a breakthrough in HIV research that had eluded scientists for over 20 years, potentially leading to better treatments for HIV, in a study published today in the journal Nature.
Viral phenomenon: Ancient microbe invaded human DNA
Humans carry in their genome the relics of an animal virus that infected their forerunners at least 40 million years ago, according to research published Wednesday by the British science journal Nature.
Graduate student finds a 'start/stop switch' for retroviruses
A University of British Columbia doctoral candidate has discovered a previously unknown mechanism for silencing retroviruses, segments of genetic material that can lead to fatal mutations in a cell's DNA.
Dormant ancient chimp virus revived
Scientists link chronic fatigue ailment to retrovirus
(PhysOrg.com) -- Scientists have discovered a potential retroviral link to chronic fatigue syndrome, known as CFS, a debilitating disease that affects millions of people in the United States. Researchers from the Whittemore ...
Unexpected viral 'fossils' found in vertebrate genomes
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 ...
Do viruses make us smarter?
A new study from Lund University in Sweden indicates that inherited viruses that are millions of years old play an important role in building up the complex networks that characterise the human brain.
Fewer viral relics may be due to a less bloody evolutionary history
Humans have fewer remnants of viral DNA in their genes compared to other mammals, a new study has found. This decrease could be because of reduced exposure to blood-borne viruses as humans evolved to use tools rather than ...
The viruses within -- and what keeps them there (w/ Video)
It is known that viral "squatters" comprise nearly half of our genetic code. These genomic invaders inserted their DNA into our own millions of years ago when they infected our ancestors. But just how we keep ...
New tales told by old infections
Retroviruses are important pathogens capable of crossing species barriers to infect new hosts, but knowledge of their evolutionary history is limited. By mapping endogenous retroviruses (ERVs), retroviruses whose genes have ...
HIV's ancestors 'plagued first mammals'
(PhysOrg.com) -- The retroviruses which gave rise to HIV have been battling it out with mammal immune systems since mammals first evolved around 100 million years ago - about 85 million years earlier than ...
Fears for koalas as study reveals 'marked decline'
Australia's much-loved koala is under increasing threat and should be considered a vulnerable species, an official report found Thursday, with habitat loss seeing their numbers plunge.
Koala study reveals clues about origins of the human genome
Eight percent of your genome derives from retroviruses that inserted themselves into human sex cells millions of years ago. Right now the koala retrovirus (KoRV) is invading koala genomes, a process that ...
New knowledge about host-virus coevolution unmasked from the genomic record
Retroviruses are important pathogens, which have attacked vertebrate hosts for millions of years. Researchers from Uppsala University and Lund University, now provide new knowledge about the long-term interactions of retroviruses ...
