Does your kids’ DNA matter more than which school they go to?

How well your kids do at school depends in part on the DNA you bequeathed them. What’s not clear is what we should do about this.

Scientists unveil high-sensitivity 3D technique using single-atom measurements
Posted by Genevieve Klien in categories: particle physics, quantum physics
Researchers at Griffith University working with Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) have unveiled a stunningly accurate technique for scientific measurements which uses a single atom as the sensor, with sensitivity down to 100 zeptoNewtons.
Using highly miniaturised segmented-style Fresnel lenses — the same design used in lighthouses for more than a century — which enable exceptionally high-quality images of a single atom, the scientists have been able to detect position displacements with nanometre precision in three dimensions.
“Our atom is missing one electron, so it’s very sensitive to electrical fields. By measuring the displacement, we’ve built a very sensitive tool for measuring electrical forces.” Dr Erik Streed, of the Centre for Quantum Dynamics, explained.

Chip detects Legionnaires’ bacteria in minutes, not days
Posted by Genevieve Klien in categories: biotech/medical, computing
When the water in the rooftop cooling towers of a building’s air conditioning system gets infected with Legionella bacteria, people in the building can get potentially-fatal Legionnaires’ disease. Therefore, it’s important to check that water for the bacteria on a regular basis. A new chip is promised to do it faster than ever.
The typical method of checking for Legionella involves putting a water sample in a Petri dish, then waiting 10 to 14 days to see if any bacterial cultures grow. Unfortunately, populations of Legionella can reach outbreak levels is as short a period as one week. Additionally, if an outbreak has already occurred, then its source needs to be ascertained as fast as possible.
That’s why the new LegioTyper chip was created.

New Room-Temperature Maser Uses Weird Diamond to Succeed Where Others Failed
Posted by Genevieve Klien in categories: particle physics, space
Scientists have used the same technology that brought us time crystals to create a room-temperature maser—a microwave laser—that overcomes many of masers’ past problems.
Masers predate lasers. They’re pretty much the same thing, but masers shoot out microwave light instead of visible or infrared light. Lasers have always been more popular, since masers have only worked in short pulses and required incredibly cold temperatures and vacuums to operate. But now, a team of scientists in the United Kingdom has overcome both old and new challenges to debut their continuously emitting, room-temperature maser. Their research was published this week in Nature.
Masers and lasers operate on basically the same principle. Atoms typically have electrons orbiting their nuclei in specific energy levels. Add some energy in the form of, say, a photon, and the electrons jump to higher energy levels. Pump enough of those electrons into the same higher energy level, and you can release a cascade of photons of the same color (or wavelength, in physics speak) whose waves line up.

Interventions to Extend Healthspan and Lifespan 2018
Posted by Steve Hill in category: life extension
This spring happens to be rich with events promoting research on aging. Just one month after the Undoing Aging conference, jointly organized by the SENS Research Foundation and the Forever Healthy Foundation, we are expecting yet another visionary event in Kazan, Russia that might prove to be another great gift to our community.
Supervised by one of the most active proponents of aging research in Russia, RAS Correspondent Member Dr. Alexey Moskalev, the fifth international Interventions to Extend Healthspan and Lifespan conference will be held in Kazan on April 23–25, 2018.
The conference will gather brilliant scientists from all over the world in one place. To make it more comfortable for international guests, an English translation will be provided for all talks.
