Tech Xplore / The giant fire tornado that could save our oceans

In the frantic hours following an offshore oil spill, emergency responders face a destructive decision: let the oil spread or ignite it. Once ignited, it creates an "in-situ" fire pool that stops the oil from spreading and ...

Phys.org / Twelve-year tracking suggests killer whales do not always drive shark disappearances

While killer whales (Orcinus orca) can trigger the immediate departure of white sharks (Carcharodon carcharias), extended absences from their aggregation sites are also part of the sharks' natural behavior, new research reveals.

Phys.org / A hidden step before meiosis could reshape efforts to treat infertility

In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a group of specialized cells, known as "germ cells," which will later form sperm and eggs, these inherited ...
