The absence of a one specific species of gut bacteria causes social deficits in mice, researchers at Baylor College of Medicine report June 16, 2016 inCell. By adding this bacteria species back to the guts of affected mice, the researchers were able to reverse some of their behavioral deficits, which are reminiscent of symptoms of…

Scientists just detected this life-forming molecule in interstellar space for the first time
For the first time ever, scientists have detected a complex organic molecule called a chiral molecule in the reaches of interstellar space, and the discovery could greatly enhance our understanding of how biological life came to be on Earth – and maybe even life's prospects for evolving elsewhere in the galaxy. The molecule in question,…

Major Cell Phone Radiation Study Reignites Cancer Questions
Federal scientists released partial findings Friday from a $25-million animal study that tested the possibility of links between cancer and chronic exposure to the type of radiation emitted from cell phones and wireless devices. The findings, which chronicle an unprecedented number of rodents subjected to a lifetime of electromagnetic radiation starting in utero, present some…

Not unexpectedly, a new drug-resistant ‘superbug’ pops up in the United States
For years, public health experts have warned us that deadly bacteria are developing resistance to all our available antibiotics. This week, researchers reported the first known U.S. case of anEscherichia coli infection resistant to colistin, a harsh drug seen as a last resort to knock out stubborn infections. The finding, described in the American Society…

99-million-year-old ‘unicorn ant’ boasted a bizarre prey-catching horn
A new ant species discovered in pieces of 99-million-year-old Myanmar amber might not have the magic of a unicorn—but it does have a bulbous horn bursting from the top of its head. The protrusion is unique amongst ants, researchers report this week in Current Biology. The underside of the horn is covered in tiny hairs,…

Hail the Hydra, an Animal That May Be Immortal
In ancient Greek myth, the Hydra was a multi-headed monster that grew two more heads for every one that it lost. As it turns out, the real-life animal named after this mythical beast may be even more tenacious. A new study finds that hydra — spindly, freshwater polyps — can live seemingly forever, without aging. Unlike…

Lifespan: Genetic background and physical activity both matter
Animal studies have already shown that a strong link exists between genetic background and physical activity level. The purpose of our study was to investigate the associations between genetic background, physical activity level, and lifespan. Observational follow-up studies report a strong relationship between high physical activity level and long lifespan. In addition, animal tests have…

Biologically powered chip created
Columbia Engineering researchers have, for the first time, harnessed the molecular machinery of living systems to power an integrated circuit from adenosine triphosphate (ATP), the energy currency of life. They achieved this by integrating a conventional solid-state complementary metal-oxide-semiconductor (CMOS) integrated circuit with an artificial lipid bilayer membrane containing ATP-powered ion pumps, opening the door…

Accidental discovery of how to stay young for longer works in worms
Living longer usually means a longer dotage, but wouldn't it be enticing to extend young adulthood instead? It's such an appealing prospect that scientists who are announcing success with roundworms are keen to be clear they are a long way from achieving it in humans. "We don't want people to get the impression they can…

Genes for a longer, healthier life found
Driven by the quest for eternal youth, humankind has spent centuries obsessed with the question of how it is exactly that we age. With advancements in molecular genetic methods in recent decades, the search for the genes involved in the aging process has greatly accelerated. Until now, this was mostly limited to genes of individual…
