Family tree of 400 million people shows genetics has limited influence on longevity
A new study by Calico found that our genes determine our lifespan much less than previously accepted and lifespan heritability is less than seven percent.
Although long life tends to run in families, genetics has far less influence on life span than previously thought, according to a new analysis of an aggregated set of family trees of more than 400 million people. The results suggest that the heritability of life span is well below past estimates, which failed to account for our tendency to select partners with similar traits to our own. The research, from Calico Life Sciences and Ancestry, was published in Genetics.
“We can potentially learn many things about the biology of aging from human genetics, but if the heritability of life span is low, it tempers our expectations about what types of things we can learn and how easy it will be,” says lead author Graham Ruby. “It helps contextualize the questions that scientists studying aging can effectively ask.”
Ruby’s employer, Calico Life Sciences, is a research and development company whose mission is to understand the biology of aging. They teamed up with scientists from the online genealogy resource Ancestry, led by Chief Scientific Officer Catherine Ball, to use publicly available pedigree data from Ancestry.com to estimate the heritability of human life span.

Therapy that Dramatically Slows Alzheimers has Passed Final Clinical Phase
Through a new approach dubbed AMBAR, the biotechnology company Grifols has attempted to reduce the amount of harmful, Alzheimer’s disease-causing amyloid beta in the brain by collecting it with a blood protein called albumin and draining it out of the bloodstream. This approach differs from the previous antibody and catabody approaches and offers new hope for sufferers of this neurodegenerative disease.
What is Alzheimer’s disease?
Alzheimer’s disease, named after its discoverer, is a slow and progressive disease that causes the degradation of the brains of its sufferers. This leads to memory loss, a decrease in problem-solving abilities, changes in personality, and other symptoms. It is associated with the accumulation of tau and amyloid beta in the brain.
In materials hit with light, individual atoms and vibrations take disorderly paths
‘’Until now, scientists assumed this all happened in a smooth, coordinated way. ‘’… silly scientists 🤔🙈🤦♂️.
Hitting a material with laser light sends vibrations rippling through its latticework of atoms, and at the same time can nudge the lattice into a new configuration with potentially useful properties – turning an insulator into a metal, for instance.
Until now, scientists assumed this all happened in a smooth, coordinated way. But two new studies show it doesn’t: When you look beyond the average response of atoms and vibrations to see what they do individually, the response, they found, is disorderly.
Atoms don’t move smoothly into their new positions, like band members marching down a field; they stagger around like partiers leaving a bar at closing time.
Wellcome and Gates join bold European open-access plan
The Wellcome Trust, which gave out £1.1 billion (US$1.4 billion) in grants in 2016–17, is also the first funder to detail how it intends to implement Plan S. Its approach suggests that journals may not need to switch wholesale to open-access (OA) models by 2020 to be compliant with Plan S — if the initiative’s other backers decide on a similar line.
The Wellcome Trust has also announced how it will implement the plan, which could provide a blueprint for others.
Cigar-shaped interstellar object may have been an alien probe, Harvard paper claims
A mysterious cigar-shaped object spotted tumbling through our solar system last year may have been an alien spacecraft sent to investigate Earth, astronomers from Harvard University have suggested.
The object, nicknamed ‘Oumuamua, meaning “a messenger that reaches out from the distant past” in Hawaiian, was first discovered in October 2017 by the Pan-STARRS 1 telescope in Hawaii.
Since its discovery, scientists have been at odds to explain its unusual features and precise origins, with researchers first calling it a comet and then an asteroid, before finally deeming it the first of its kind: a new class of “interstellar objects.”

SpaceX Rehearses Recovery of Astronauts During Ocean Landings, Builds Helipad on Ship
SpaceX has started preparations for recovering International Space Station (ISS) astronauts during ocean touchdowns, conducting landing and patient loading rehearsals on their recovery ship GO Searcher.
NASA recently shared photos of the rehearsals on board GO Searcher, which has been upgraded with a medical treatment facility and a helipad in the center of the vessel.
SpaceX practiced how the helicopter will pick up astronauts and fly them to a nearby hospital, in case of a medical emergency.
