Telecom provider AT&T this week said some local customers now have access to faster internet with the addition of 2 gigabit and 5 gigabit fiber internet to the community. Reno is one of more than 70 metro regions in the country to get the upgrade.

The top speeds for AT&T fiber internet had previously been 1 gig.

AT&T officials said the rollout of the improved fiber network for residential customers was in response to pandemic shifts in how people work, with many more people setting up home offices or making their homes a permanent workplace.

The Lifeboat Foundation is a nonprofit nongovernmental organization dedicated to encouraging scientific advancements while helping humanity survive existential risks and possible misuse of increasingly powerful technologies, including genetic engineering, nanotechnology, and robotics/AI, as we move towards the Singularity.

Lifeboat Foundation is pursuing a variety of options, including helping to accelerate the development of technologies to defend humanity, such as new methods to combat viruses, effective nanotechnological defensive strategies, and even self-sustaining space colonies in case the other defensive strategies fail.

A platform for single-molecule measurement of binding kinetics & enzyme activity.

The first molecular electronics chip has been developed, realizing a 50-year-old goal of integrating single molecules into circuits to achieve the ultimate scaling limits of Moore’s Law. Developed by Roswell Biotechnologies and a multi-disciplinary team of leading academic scientists, the chip uses single molecules as universal sensor elements in a circuit to create a programmable biosensor with real-time, single-molecule sensitivity and unlimited scalability in sensor pixel density. This innovation, appearing this week in a peer-reviewed article in the Proceedings of the National Academy of Sciences (PNAS), will power advances in diverse fields that are fundamentally based on observing molecular interactions, including drug discovery, diagnostics, DNA

Many of the all-too-familiar symptoms of aging can be attributed to a build-up of senescent cells, those which have stopped dividing. In a new study, researchers in Japan have identified a protein specific to these cells and developed a vaccine that can clear them away, with tests on mice reducing the effects of aging.

Cells cannot keep dividing forever – eventually they accumulate too much DNA damage through environmental stress, so the body shuts them down and flags them to be cleared out by the immune system. This seems to be an evolutionary defense mechanism against cells turning cancerous.

However, even immune cells aren’t immune from this process, and as they become senescent themselves the immune system gradually loses the ability to clear out senescent cells. As these inactive cells accumulate in the body, they contribute to symptoms of aging and the diseases that come with it.

“It was either die or do this transplant. I want to live. I know it’s a shot in the dark, but it’s my last choice,” said Bennett.

The heart was provided by Revivicor, a company based in Virginia that has been engineering pig organs for roughly two decades. In several experiments for pig-to-baboon transplants, the organs survived up to nine months, until the animals passed away due to a lung infection unrelated to the transplant.

Overall, the heart had 10 hefty genetic edits. Three of them wiped out sugar molecules on the outside of cells that provoke an immune response. Six bolstered the chance of the human host accepting the heart—amping up an anti-inflammatory response, preventing blood vessel damage, and dampening any antibodies against the organ. Finally, the last edit limited the pig heart’s size. Although it generally matched the size of a human heart, the team wanted to prevent the pig organ from overgrowth inside Bennett’s chest once it was transplanted—something they previously noticed happened in baboons.

Over the last year home prices have skyrocketed (along with prices of almost everything else), leaving millions of people unable to afford to move or to change their housing situation. Mortgage lender Freddie Mac estimated last year that the US has a housing supply shortage of 3.8 million homes. It’s partly Covid-related; construction has slowed due to labor shortages, high raw material costs, and supply chain issues—but the problem predates the pandemic, as demand for homes was already outpacing supply in 2019.

Middle-and low-income families have been hit hardest by the housing shortage. In an effort to assist those in need, Habitat for Humanity launched an initiative last year to incorporate 3D printing into its construction process to cut costs. The first home was completed last month, and a family moved in just before Christmas.

For millions of patients who have lost limbs – for reasons ranging from diabetes to trauma – the possibility of regaining function through natural regeneration remains out of reach. The regrowth of legs and arms remains limited to animals such as salamanders and the realm of science fiction.

However, a new study published in the journal Science Advances, by scientists at Tufts University and Harvard University’s Wyss Institute, has brought us a step closer to the goal of regenerating human limbs.

On adult frogs, which are naturally unable to regenerate limbs, a research team succeeded in triggering regrowth of a lost leg using a five-drug cocktail applied in a silicone wearable bioreactor dome that seals over the stump for just 24 hours. That brief treatment sets in motion an 18-month period of regrowth that eventually restores a functional leg.

A standard feature on its Model S, Model X, and Model Ys since 2016.

As Tesla explains in the description accompanying the video, it uses highly efficient particulate air (HEPA) filters in its car models S, X, and Y. The air filtration system removes more than 99 percent of particulates and is something we also saw in some other EV concepts last year.
