Anaplasmosis, a tick-borne febrile disease, can be carried by wild mammals before being transmitted to humans through a tick bite. Now, researchers reporting in PLOS Neglected Tropical Diseases have found that Anaplasma bacteria alter the patterns of other microbes in the spleens of mice and shrews.
The spleen, in mammals, acts as a blood filter. While...
A study reported in the journal Science offers an enhanced view of the origins and ultimate fate of the first dogs in the Americas. The dogs were not domesticated North American wolves, as some have speculated, but likely followed their human counterparts over a land bridge that once connected North Asia and the Americas, the...
Blood from horseshoe crabs is essential for many drug, implant and environmental safety tests -- but blood harvesting, together with capture for bait and impacts from climate change and habitat destruction, is threatening populations of these "living fossils." A review published in Frontiers in Marine Science highlights that these continuing threats will detrimentally affect the...
Northern White Rhinos (NWR) are functionally extinct, as only two females of this species are left on the planet. An international team of scientists has now successfully created hybrid embryos from Southern White Rhino (SWR) eggs and NWR sperm using assisted reproduction techniques (ART). This is the first, ever reported, generation of blastocysts (a pre-implantation...

Scientists have attributed the flying behaviour of these wingless...
Researchers from the University of Turku, Finland have discovered a new wasp species in the Amazon which has an exceptionally large stinger that surprised even the scientists.
