Our brains may ripple before remembering

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

As many labs have established, Dr. Zaghloul’s team knew that our episodic memories are controlled by neurons in at least two different parts of the brain, but they did not know exactly how the cells worked together to retrieve memories. Based on a growing of body of evidence, they suspected that the short, high frequency electrical waves seen in ripples may somehow be involved. For instance, two earlier patient studies suggested that ripples may be important for solidifying memories during sleep.

A sound, a smell, a word can all flood our minds with memories of past experiences. In a study of epilepsy patients, researchers at the National Institutes of Health found that split seconds before we recall these events tiny electrical waves, called ripples, may flow through key parts of our brains that help store our memories, setting the stage for successful retrieval.

“We showed for the first time that may be the neural substrates through which the successfully recalls memories,” said Kareem Zaghloul, M.D., Ph.D., a neurosurgeon-researcher at the NIH’s National Institute of Neurological Disorders and Stroke (NINDS) and senior author of the study published in Science. “These results help us understand how the processes the details of our past waking experiences or episodic memories.”

Humans could regrow limbs as scientists uncover a ‘DNA switch’

Posted by in category: biotech/medical

It is decades away but a team in Germany did use a regenerative method on an amputees finger stumps with positive results in 2003.

Scientists from Harvard University in Massachusetts have discovered a ‘DNA switch’ that we could use to grow back parts of our bodies like animals who can regenerate, like jellyfish.

Skin-deep microchips pave the way for ‘transhumanism’

Posted by in categories: computing, cyborgs, neuroscience, transhumanism

Last year, the Japan Transhumanist Association, a general incorporated group that aims to promote transhumanism in Japan, used Twitter to solicit volunteers for free chip implants. More than 20,000 people applied, and 20 are currently being prepared for the procedure.

With microchip implants, humankind has taken a step toward what future-minded experts predict will be a world filled with cyborgs, but Japan lags behind other countries in this regard.

The microchips inserted under the skin are currently limited to such tasks as opening doors and paying for small items, like drinks.

Astronomers have discovered hundreds of thousands of new galaxies in a tiny section of the universe

Posted by in category: cosmology

Over 200 experts worked on developing the new radio telescope, which is exploring space in a entirely new way.

  • According to an Astronomy & Astrophysics press release, astronomers from 18 countries have discovered hundreds of thousands of previously unknown galaxies.
  • Over 200 experts worked on developing the new radio telescope, which will explore space in a entirely new way.
  • The telescope’s capabilities may also allow the researchers to delve further into the behaviour of black holes.

According to preliminary findings in a study published in Astronomy & Astrophysics, scientists have recently discovered hidden galaxies in our universe — and they’ve found hundreds of thousands of them.

Together, over 200 experts across 18 different countries have developed a new radio telescope that will explore space in a completely new way.

Amazon removes books that promoted an autism ‘cure’

Posted by in categories: biotech/medical, neuroscience

NEW YORK (AP) — Amazon has removed books from its website that promoted “cures” for autism, the latest major company to try to limit the amount of misinformation related to autism and the bogus notion that it’s caused by vaccines.

The Center for Disease Control and Prevention says there is no cure for autism spectrum disorder, only medications that can help some function better. It also says there is no link between vaccines and autism.

An Inc. spokeswoman confirmed the books were no longer available, but did not answer any additional questions.

Spaceflight found to reactivate dormant viruses in astronauts

Posted by in categories: biotech/medical, health, space travel

There are certainly a whole host of technological hurdles to overcome before humans successfully travel to Mars, or beyond, but research is also pointing to a growing assortment of fundamental health challenges that astronauts may face from long stretches of time in space. A recent NASA-funded study has found dormant viruses can reactivate in the human body during spaceflight, presenting yet another physiological problem for scientists to solve before we journey out into deep space.

Cryopreservation of Valia Zeldin

Posted by in categories: cryonics, life extension

Text by Anton Zeldin, source: by Alexey Turchin with the help of Google translate.

I started to date Valya in 2011 after the championship in “crocodile” — a game in which you need to portray words with the help of pantomime and guess them. For several years we communicated in very different ways, either parting or renewing relations, and only in 2016 we finally engaged. I realized that everything that I like to do in life, with this person I like even more. On both sides there was a confidence that no matter how we quarrel, nothing will change. We felt that a large concrete slab was laid at the base of our relationship.

In May 2017, we got married and started thinking about moving to Moscow. We worked together a lot — we made a discussion club and a telegram training game. It seemed to us that for the development of the latter it was important to be in the capital. We moved in mid-October, and lived in Moscow for almost a year. September 2, 2018 Valya shot down.
