Chimpanzees are being forced to eat bat feces, and the viruses in itResearchers in Uganda have noticed a new behaviour in the wild chimps they study. The apes are browsing on bat guano, apparently to access the nutrients it contains, as their normal source for these nutrients has been destroyed by humans. Since bats are carriers of a range of diseases, from ebola to coronaviruses, this may be a new way these diseases could spread.&nbsp;The study was published in Communications Biology. Dr Tony Goldberg, a professor of epidemiology at the school of veterinary medicine at the University of Wisconsin-Madison, was part of the team.Controversial methods are working to buy Canada’s caribou some timeWoodland caribou have been in steady decline for decades, as logging, oil and gas exploration and other disturbances compromise their western mountain habitat. Steady progress has been made to restore habitat in order to save these caribou, but since these forests will take half a century to regrow, conservationists are trying a variety of interim actions to buy the caribou some time. A new study led by Clayton Lamb from the University of British Columbia Okanagan found that these methods, including direct feeding, maternal penning, and, controversially, culling predatory wolves, have helped caribou recover to some extent, but restoration of their habitat will be necessary for full recovery. The research was published in the journal Ecological Applications.Giant ancient Pacific salmon had tusks sticking out of its faceMillions of years ago, enormous three metre-long salmon inhabited the seas of the Pacific coast. Named Oncorhynchus rastrosus, this ancient giant was first described in the 1970s as having long front fangs, which led to it being known colloquially as a “saber-toothed salmon.” But a new study published in PLOS ONE sets the record straight: the teeth actually protruded out to the sides from the fish’s upper jaw, as tusks do. Lead study author and Philadelphia College of Osteopathic Medicine professor Kerin Claeson says despite their menacing look, the salmon did not hunt with these tusks, since these strange fish were filter feeders.The Gulf oil spill may have had ecological impacts we haven’t seen yetFourteen years ago an explosion destroyed the Deepwater Horizon oil rig and kicked off the largest oil spill in history. While commercial fisheries have largely recovered from the disaster, there are signs that rarer and more vulnerable species might have been devastated. Prosanta Chakrabarty from Louisiana State University surveyed deep sea fish catalogued in museum collections around the world and found that out of 78 endemic species found only in the Gulf, 29 of them haven’t been spotted in the years since the spill. The research was published in the Biodiversity Data Journal.Primordial black holes may be the solution the problem of missing dark matterThe hunt for exotic black holes that Stephen Hawking first predicted back in the 1970s is now well underway. Primordial black holes behave just like any other black hole, but they would have&nbsp; formed in the early universe and could&nbsp; be any size. Many scientists are particularly interested in the primordial black holes that are the size of an atom and have the mass of an asteroid because they suspect they could be the answer for the missing dark matter in our universe.&nbsp;
