By Will Boggs MD (Reuters Health) - Brain cells - neurons - develop gene mutations over the course of a lifetime, contributing to normal aging and potentially presenting a target for treatments that stave off dementia and other types of cognitive decline, researchers say. The team developed a way to sequence the genomes of individual neurons, which allowed them to see what changes are normal and also what happens in specific brain diseases. "The work is at a very early stage,” senior study author Dr. Christopher A. Walsh from Harvard Medical School in Boston told Reuters Health by email.
In March 2018, experimental biologist Itamar Harel will open a research lab at the Hebrew University of Jerusalem to study the killifish, according to news site ISRAEL21c. Harel told Newsweek that it's the shortest-lived vertebrate that can still be grown in a lab. The killifish's aging process shares a number of similarities to our own.
Giant penguins, standing over 5 feet tall and weighing more than 220 pounds, may have roamed Earth some 60 million years ago, according to new research. Scientists on Tuesday said they discovered fossils of an ancient penguin that may have stood 5 foot 7 — nearly the height of the average American male — and weighed about 225 pounds, according to a Nature Communications research report. It would dwarf the emperor penguin, the biggest penguin today, which is less than 4 feet tall.
Archaeologists excavating a medieval grave in Bulgaria discovered an unidentified body with an arrow in its chest. The grave, in the southern Bulgarian city of Plovdiv, is dated to around the 11th or 12th century. The gender of the deceased has not been specified, but archaeologists believe that the arrow was either the cause of death, or was placed there afterward symbolically, according to Archaeology in Bulgaria.
(Reuters) - A capsule carrying U.S., Russian and Italian astronauts from the International Space Station landed in Kazakhstan on Thursday after a five-month mission, a NASA TV live broadcast showed. The spacecraft brought back Randy Bresnik from the U.S. National Aeronautics and Space Administration, Sergey Ryazanskiy from Russian space agency Roscosmos, and Italy's Paolo Nespoli with the European Space Agency. The capsule landed in the windswept and snow-covered steppe in Kazakhstan's central Karaganda region at 2.37 p.m. (0837 GMT). ...
