Viral DNA in human genomes, embedded there from ancient infections, serve as antivirals that protect human cells against certain present-day viruses, according to new research.

Study shows hazardous herbicide chemical goes airborne
"Dicamba drift" -- the movement of the herbicide dicamba off crops through the atmosphere -- can result in unintentional damage to neighboring plants. To prevent dicamba drift, other chemicals, typically amines, are mixed with dicamba to "lock" it in place and prevent it from volatilizing, or turning into a vapor...
Experimental monoclonal antibodies show promise against Epstein-Barr virus
A panel of investigational monoclonal antibodies (mAbs) targeting different sites of the Epstein-Barr virus (EBV) blocked infection when tested in human cells in a laboratory setting. Moreover, one of the experimental mAbs provided nearly complete protection against EBV infection and lymphoma when tested in mice.
Ozone hole continues shrinking in 2022, NASA and NOAA scientists say
The annual Antarctic ozone hole reached an average area of 8.9 million square miles (23.2 million square kilometers) between Sept. 7 and Oct. 13, 2022. This depleted area of the ozone layer over the South Pole was slightly smaller than last year and generally continued the overall shrinking trend of...
Why some people are mosquito magnets
The female mosquito will hunt down any human, but some of us get bitten far more than others. The answer why may be hidden in our skin.
River longer than the Thames beneath Antarctic ice sheet could affect ice loss
An unexpected river under the Antarctic ice sheet affects the flow and melting of ice, potentially accelerating ice loss as the climate warms.
High-res maps of entire polar regions provide new clues for climate researchers
A team of researchers has released four more years of high-resolution imagery data, which has been added to eight years of previous data, to create the most detailed polar region terrain maps ever created.
Revolutionary technique to generate hydrogen more efficiently from water
Researchers have made a serendipitous scientific discovery that could potentially revolutionize the way water is broken down to release hydrogen gas -- an element crucial to many industrial processes. The team found that light can trigger a new mechanism in a catalytic material used extensively in water electrolysis, where water...
‘Forever chemicals’ persist through wastewater treatment, may enter crops
PFAS (per-and polyfluoroalkyl substances) persist through wastewater treatment at levels that may impact the long-term feasibility of 'beneficial reuse of treated wastewater,' according to a new study.
As Sea Ice Retreats, Narwhals Are Changing Their Migration Patterns
Narwhals are changing their migration patterns in response to pressure from changing Arctic climates, a new UBC report has found.
