All children to receive whole genome sequencing at birth, under ambitions laid out

Posted by in categories: biotech/medical, genetics, health

All children will be able to receive whole genome sequencing at birth, under ambitions laid out by the Health Secretary.

Matt Hancock said that in future, the tests would be routinely offered, alongside standard checks on newborns, in order to map out the risk of genetic diseases, and offer “predictive, personalised” care.

Ministers have already promised that such tests will be offered to all children diagnosed with cancer by the end of this year.

Scientists pinpoint the fastest way to learn something new

Posted by in categories: education, information science, robotics/AI

Learning something new — and quickly — may depend on the lesson’s difficulty level, according to a new study.

Flipping the classroom, room temperature, and later school-day start times, are just a few of the countless interventions scientists have tested and some educators have implemented.

Now, scientists say they have cracked the code on the optimal level of difficulty to speed up learning. The team tested how the difficulty of training impacts the rate of learning in a broad class of learning algorithms, artificial neural networks, and computer models thought to simulate learning in humans and animals.

In this issue, top experts examine technology-related doomsdays the world might soon face if they go unaddressed, not to frighten readers, but to alert them, so they might act in time, making a loud and unmistakable demand: that the Earth be preserved, that the human experiment be extended, that midnight never toll.

Scientists Have Made a Blueprint For a Quantum Battery That Never Loses Charge

Posted by in categories: mobile phones, quantum physics

A team of scientists from the universities of Alberta and Toronto have laid out the blueprints for a “quantum battery” that never loses its charge.

To be clear, this battery doesn’t exist yet — but if they figure out how to build it, it could be a revolutionary breakthrough in energy storage.

“The batteries that we are more familiar with — like the lithium-ion battery that powers your smartphone — rely on classical electrochemical principles, whereas quantum batteries rely solely on quantum mechanics,” University of Alberta chemist Gabriel Hanna said in a statement.

Cell senescence contributes to tissue regeneration in zebrafish

Posted by in categories: biotech/medical, life extension

Tissue injury‐induced senescence is conserved in zebrafish. Fin amputation in adult fish lead to the appearance of senescent cells at the site of damage, and their removal impairs tissue regeneration…

Scientists extend mice lifespan 12%

Posted by in categories: biotech/medical, genetics, life extension

Scientists successfully extended the average lifespan of mice by breeding them using embryonic stem cells with extra-long telomeres. The findings are significant because the researchers managed to extend lifespan without genetic modification, and they also shed light on the aging process and techniques that might someday slow it.

The study — published October 17 in Nature Communicationsfocuses on telomeres, which are stretches of DNA found at the end of chromosomes.

Because telomeres protect the genetic material inside chromosomes, they’ve been likened to the plastic tips on the ends of shoelaces. But telomeres have also been compared to bomb fuses, or “molecular clocks,” because they become shorter each time a cell divides, eventually shrinking so much that the cell dies or stops dividing. This shortening of our telomeres is associated with aging, cancer, and death.

The second objective is propulsion. This is achieved by emitting pulsed cathode rays out of one end of the craft tuned to the rate of change of jet stream particles surrounding the bubble. At the other end of the craft, cations are emitted at the same rate of change. This creates a push/pull effect, doubling the ship’s acceleration and velocity capabilities.
