Viruses in the gut protect from infection
“Mucus is everywhere,” says microbiologist Jeremy Barr. Almost every animal uses it to make a barrier that protects tissues that are exposed to the environment, such as the gut or lungs. Now, Barr and a team of researchers have discovered that mucus is also the key to an ancient partnership between animals and viruses. Viruses […] (Source: Biosingularity)

Human embryonic stem cells created from adult tissue for first time
Scientists have used the cloning technique that led to Dolly the sheep to turn human skin into embryonic stem cells – which can make any tissue in the body. The US team overcame technical problems that had frustrated researchers for more than a decade to create batches of the bodys master cells from donated skin. […] (Source: Biosingularity)

Having A Pet May Lower Heart Disease Risk
They’re man’s best friend, and they may be one of the heart’s best allies as well.A panel of heart disease experts convened by the American Heart Association AHA reviewed research linking heart health and owning a pet and found that owning a pet is “probably associated” with a lower risk of heart disease for those […] (Source: Biosingularity)

Almond-Sized Brain Region is Control Centre for Ageing
In a New York laboratory, a special group of mice is destined to outlive their cage-mates. Their muscles will stay strong for longer. Their brains will stay sharp for longer. When they eventually die, they will have seen more months than their peers.The secret to their longevity isn’t a drug or a special diet. Instead, […] (Source: Biosingularity)

The Neurobiology of Individuality
When a group of genetically identical mice lived in the same complex enclosure for 3 months, individuals that explored the environment more broadly grew more new neurons than less adventurous mice, according to a study published today (May 9) in Science. This link between exploratory behavior and adult neurogenesis shows that brain plasticity can be […] (Source: Biosingularity)

Two-year-old girl receives new trachea made from her own stem cells | The Verge
Doctors announced today that two-and-a-half year old Hannah Warren just became the youngest person in history to receive a bioengineered organ transplant, a new windpipe made of a synthetic scaffold and her own stem cells. The nine-hour long procedure was performed April 9th, at Children’s Hospital of Illinois in Peoria, but the results were just […] (Source: Biosingularity)

A Sleep Gene Has A Surprising Role In Migraines
Mutations on a single gene appear to increase the risk for both an unusual sleep disorder and migraines, a team reports in Science Translational Medicine. The finding could help explain the links between sleep problems and migraines. It also should make it easier to find new drugs to treat migraines, researchers say. via A Sleep […] (Source: Biosingularity)
