Kevin bacon 13 million degrees: the world’s largest family tree illuminates the end of life, who marries who.
The researchers have published perhaps the largest family tree yet: a genealogical database dating back five centuries that links 13 million people related to blood or marriage. The tree has revealed a link between longevity and certain genes, and it provides insights into why some of our ancestors were married to them. The researchers say this is just the beginning.

You don’t know it from the excitement of the revolutionary genome-editing method CRISPR, but in practice it’s far from perfect. Its standard components can only find and cut DNA in a limited genome, and its molecular scissors oscillate, leading to “off-target” mutations. Now a team led by Harvard University chemist David Liu has designed a CRISPR version that may be more dexterous and precise.
Adaptation science: what are the ingredients that help people cope?


Many people’s minds are now resilient. Hurricanes and fires regularly hit communities, the risks of climate change are high, and the horrors of war and the refugee crisis it produces show no signs of abating. This is an unsettling period – and more so, because we humans feel we cannot control many of these events that are affected by human beings. But even if the difficulties weaken some, others bounce back. How can science teach us how to help and adapt to future challenges? A series of stories in this week’s science journal explores the resilience of scientists in a challenging world.
America’s flagship space telescope faces further delays.
The government accountability office, according to a report released this week, NASA’s James webb space telescope, is expected to be beset change our understanding of the early universe, planets around other stars, and many other stars planets, are competing for more choppy water. The problem of testing orbital telescope components and integrating them together means that further delays are possible. That could mean the project would violate the $8 billion cost ceiling imposed by congress in 2011.
Look at the caterpillar passing through its beetle attackers in the air.
Soft, soft caterpillars look like a hungry predator, but a species will not give up without a fight. Fully developed caterpillars use squeaks, blows and vomit to protect predators, according to a new study. The scientists tested the behaviour of earthworm moth caterpillars in the search for caterpillars, and found that none of the 25 beetles tested successfully killed a caterpillar.
