Neuroscientists are paying more attention to sleep spindles, short bursts of neuronal activity thought to play a role in memory consolidation while the body is at rest.
“Spindles appear to play a central role whenever memories during sleep are undergoing transformation that might be necessary to integrate them into neocortical long-term storage networks,” Jan Born of the University of Tübingen told The Scientist during a conference dedicated to sleep spindles held in Budapest in May.
Researchers at Genentech have reportedly stopped the spread of tau without activating effector function in mouse models and in vitro.
“It is excellent to see additional studies supporting the feasibility of tau immunotherapies,” Einar Sigurdsson of New York University School of Medicine, who was not involved in the study, wrote in an email.
Sheep cloned through somatic cell nuclear transfer (SCNT) age normally, researchers from the University of Nottingham, U.K, and their colleagues have shown.
The finding “is important . . . because Dolly was under the magnifying glass for a very long time,” said Dietrich Egli of Columbia University in New York City who was not involved in the work.
Neonicotinoid exposure can reduce the fertility and longevity of male honeybees, scientists at the University of Bern, Switzerland, and their colleagues have shown.
“Because bee society relies on each caste and group of workers doing their job effectively, these sublethal effects, such as an effect on sperm quality may have very significant long-term effects on bee health,” Peter Dearden of New Zealand’s University of Otago who was not involved in the work wrote in an email to The Scientist.
Telomere transcription is increased in healthy people after they performed a cardiovascular workout, researchers at the de Duve Institute in Brussels, Belgium and colleagues reported.
Carol Greider of the Johns Hopkins Institute for Basic Biomedical Sciences who was not involved in the work told The Scientist it is not yet clear whether this correlation between exercise and telomere transcription affects aging.
