NASA unveils spaceship hatch 50 years after fatal Apollo 1 fire

By Irene Klotz CAPE CANAVERAL, Fla. (Reuters) - NASA on Friday marked the 50th anniversary of Apollo 1's fatal launchpad fire with the first public display of the scorched hatch that trapped three astronauts in the spaceship during a routine pre-launch test. NASA astronauts Virgil "Gus" Grissom, Edward White and Roger Chaffee died when thick smoke filled the crew module of the Apollo 1 capsule on Jan. 27, 1967. Emergency rescue teams rushed to battle the fire at the launchpad, located at what is now Cape Canaveral Air Force Station, but were too late.

Paris and Michael Jackson: Does Depression Run in Families?

Paris Jackson recently spoke about struggling with both depression and anxiety. When family members have the same mental health condition, is it a coincidence, the result of sharing the same household environment or evidence that the condition is heritable? Depression is "in the same class as many other complex disorders, like diabetes," in terms of its heritability, Myrna M. Weissman, a professor of epidemiology and psychiatry at Columbia University in New York, told Live Science.

Scientists Grow Mouse Pancreas Inside a Rat

In a recent experiment to help out mice that were missing their pancreases, scientists grew new pancreases from mouse stem cells in the bodies of rats, and then transplanted those pancreases into the mice. The work holds promise for alleviating the severe shortage of donated human organs, they said. "However, there is a much greater evolutionary distance between humans and pigs or sheep than there is between mice and rats, and this could create challenges," said the study's senior author, Hiromitsu Nakauchi, a stem cell biologist at the Stanford University School of Medicine in California.

Why Fancy Baby Monitors Aren't Needed for Healthy Babies

Today's high-end baby monitors do far more than just show video of a little one — some offer to measure babies' vital signs, including their breathing and heart rate, and let parents track all this info on their smartphones. There is currently no evidence that such monitors are accurate, the researchers said.Moreover, using these devices may lead to false alarms about babies'  health and safety that do not actually mean that there is something is going wrong, the researchers said. For their report, the researchers examined the features of five infant monitors that had been introduced over the past two years and had accompanying smartphone apps.

Can a Roommate's Genes Influence Your Health?

In a new study, researchers found that the genetics of a mouse's cage mate can affect its own health in a multitude of ways. "The take-away message here is that we need to pay attention to the genetic makeup of social partners, since in some cases it affects health more than the individual's own genes," said Amelie Baud, a postdoctoral fellow at the European Bioinformatics Institute in Hinxton, England, and first author on the study. "This is something we did not know before," Baud told Live Science.

Early Menopause Linked to a Woman's Reproductive History

The age at which women get their first period, along with the number of children they have, may influence when they enter menopause, a new study from Australia finds. Women in the study who got their first period before age 12 and had no children were five times more likely to experience premature menopause, and twice as likely to experience early menopause, than were women who got their first period at age 12 or later, and who had two or more children. A woman’s age at her first period and age at menopause are both markers of reproductive health, and while it's not clear what the link between the two may mean for women's overall health, a better understanding of the possible link between them "will provide us with the opportunity to monitor and intervene as early as possible," to prepare women for the possibility of things like ovarian failure or early menopause, said Gita Mishra, the lead author of the paper and an epidemiology professor at The University of Queens…

Britain plan to leave Euratom could delay new nuclear build

By Nina Chestney LONDON (Reuters) - British plans to leave the European Atomic Energy Community (Euratom) when it exits the European Union could raise costs, delay new nuclear power projects and complicate research and international cooperation agreements, experts said on Friday. On Thursday, Britain published the legislation it will use to seek parliamentary approval for triggering the process for leaving the European Union, saying the Prime Minister has the power to notify the European Council of withdrawal. Britain plans to build new nuclear reactors as it faces an electricity supply gap in the coming decade, the biggest of which is the $24 billion Hinkley Point C project being built by French utility EDF.
