During his year in space, Scott Kelly was zapped relentlessly by radiation — the equivalent of 10 chest X-rays a day for more than 11 months starting in March of 2015. The onslaught damaged the astronaut’s DNA and affected his immune system while raising his risk for cancer. And Kelly was aboard the International Space Station, whose tight orbit around Earth lies within the magnetic field that surrounds our planet and blocks the most damaging forms of radiation.

Astronauts who travel to Mars or other destinations in deep space will leave Earth’s protective cocoon for months or years at a time. And a new NASA-funded study suggests that chronic exposure to radiation could harm astronauts’ minds as well as their bodies — potentially affecting space flyers’ moods and even their ability to think.

That could be a big deal.

One of the most difficult challenges in treating the brain cancer glioblastoma is that few drugs can pass through the blood-brain barrier. Scientists at Cedars-Sinai in Los Angeles have developed a system to circumvent this hurdle—one that combines a powerful immuno-oncology drug with a polymer-based delivery vehicle that can cross the blood-brain barrier.

The researchers showed that this “nano-immunotherapy” treatment crossed the blood-brain barrier in mouse models of glioblastoma, and that it stopped tumor cells from multiplying. They published their findings in the journal Nature Communications.

The Cedars-Sinai team used the polymer scaffold to deliver two types of immune checkpoint inhibitors, blocking either CTLA-4 or PD-1. When injected into the bloodstream of mice, the drugs quickly infiltrated brain tumors, but not healthy brain tissue, the researchers reported.

Researchers have successfully created a model of the Universe using artificial intelligence, reports a new study.

Researchers seek to understand our Universe by making to match observations. Historically, they have been able to model simple or highly simplified physical systems, jokingly dubbed the “spherical cows,” with pencils and paper. Later, the arrival of computers enabled them to model complex phenomena with . For example, researchers have programmed supercomputers to simulate the motion of billions of particles through billions of years of cosmic time, a procedure known as the N-body simulations, in order to study how the Universe evolved to what we observe today.

“Now with , we have developed the first neural network model of the Universe, and demonstrated there’s a third route to making predictions, one that combines the merits of both analytic calculation and numerical simulation,” said Yin Li, a Postdoctoral Researcher at the Kavli Institute for the Physics and Mathematics of the Universe, University of Tokyo, and jointly the University of California, Berkeley.

She’s now leading her own $39m Longevity Fund that supports entrepreneurs developing therapies for age-related diseases.

Born in New Zealand, Deming was home-schooled by her parents but as a child taught herself calculus, probability and statistics as well as French literature and history.

After her grandmother Bertie developed neuro-muscular problems in her 70s and 80s, she decided to dedicate her life to combating the ageing process.

The rise of cryptocurrency is changing the philanthropic world by causing the redistribution of wealth from old money to visionary innovators and early tech adopters. The new crypto rich invest their donations by supporting scientific research in groundbreaking fields that may one day enable humanity to cure aging, reverse death and completely change the relationship between work and income.

Examining the record of donations made by the crypto rich reveals a pattern of support for goals that others may feel belong in the pages of science fiction novels. Having benefited greatly from recognizing the potential of peer to peer electronic cash earlier than the masses, it is no surprise that they have great optimism in the power of technology to radically change our lives for the better.

As destructive natural phenomena go, hurricanes are among the heavyweights. If not for the gale-force winds and resulting projectile debris, then for the massive flooding that results when one makes landfall and stalls out, a hurricane is a nasty piece of work. Just ask the residents of the coastal Carolinas and Georgia this week as they wring themselves out from Hurricane Matthew’s weekend deluge.
