O.o now more people :0.

God Speed, I look forward to seeing you in battle.

Researchers report ultraprecise imaging of a postmortem human brain.

We need worms

You might think they are disgusting. But our war against intestinal worms has damaged our immune systems and mental health.

A recently released study from Maria Blasco and her team of researchers at the Spanish National Cancer Research Center (CNIO) shows that the rate of telomere shortening is strongly correlated with the maximum lifespan of animal species.

Telomeres

Telomeres, which are simply repeating segments of DNA on the ends of our chromosomes, serve two critical functions: They protect the ends of our chromosomes, preventing genetic damage, and they serve as a clock, limiting the number of times that our cells can divide. This limit, known as the Hayflick limit, serves as a basic defense against cancer. However, telomere attrition is a primary hallmark of aging and leads to cellular senescence and other age-related disorders.

“We cannot directly image what’s going on near objects like black holes and neutron stars, but studying the polarization of X-rays emitted from their surrounding environments reveals the physics of these enigmatic objects,” Paul Hertz, director of NASA’s astrophysics division, said in a statement at the time. The project, he said, “will open a new window on the universe for astronomers to peer through.”

A preliminary launch date is set for April 2021 on a Falcon 9 rocket from Launch Complex 39A in Florida. It’s unlikely it will take up the full payload of the rocket, as SpaceNews.com points out.

A team of researchers led by scientists in Vienna, Dresden and Heidelberg has decoded the entire genetic information of the Mexican salamander axolotl. The axolotl genome, which is the largest genome ever to be sequenced, will be a powerful tool to study the molecular basis for regrowing limbs and other forms of regeneration.

Salamanders have long served as valuable biological models for developmental, regeneration and evolutionary studies. In particular, the Mexican axolotl Ambystoma mexicanum has received special attention due to its astounding ability to regenerate body-parts. If the cannibalistically inclined animal loses a limb, it will regrow a perfect substitute within weeks, complete with bones, muscles and nerves in the right places. Even more fascinating, the axolotl can repair severed spinal cord and retinal tissue. These qualities and the relative ease in breeding have made it a favourite biological model, cultivated in the lab for more than 150 years.

This update is an adaptation of my recent answer to a Quora reader who was in a panic. She asked:

“What can I do after a hard drive crash?
How can I recover my cryptocurrency?”

In the past, I would address the immediate problem of course. (My answer is below). But to prepare for the next unfortunate event, I recommended a wallet type based on a user’s unique experience, expertise and comfort zone. I guided the reader to weigh trade-offs of important criteria: Security, portability, convenience, and quick access to assets).

I had believed that some types of wallets were better for some individuals, but that they required a background in cryptography—or at least a discipline for meticulous practices. As CEO of the Cryptocurrency Standards Association, I had also believed that simple, unified, and popular standards would emerge very soon. I figured that this would enable users to practice safe-wallet maintenance in their own homes.
