Right now the theme in space is not only billionaires crossing the Karman line… we are now looking to go further than we’ve ever ventured to study asteroids. Also, we’re trying a new tactic to see if we can successfully divert an asteroid from wiping us all out.
Lucy launched Saturday from Florida. Despite a problem with the solar array panels not latching completely, NASA is confident the mission won’t be severely impacted.
I also talked to Harvard astronomer Jonathan McDowell about the Double Asteroid Redirection Test or DART that is scheduled for November.

In a world-first, US surgeons have successfully transferred a kidney taken from a pig into a braindead human patient, in a major step towards using animal organs in human transplantations.

The team at NYU Langone Health performed the operation on a woman who was recently declared braindead, with the permission of her family. The sole object of the study, according to the lead surgeon Dr Robert Montgomery, was “to provide the first evidence that what appears to be promising results from non-human primates will translate into a good outcome in a human.”

One major obstacle in making xenotransplantation possible has been the rejection of organs by hosts. To overcome this, the team used an organ from a pig that had been genetically engineered in order to remove a sugar molecule known to play a significant role in rejection. The surgeons attached the kidney to large blood vessels outside of the recipient and monitored it for two days.

Investing bank Morgan Stanley believes that Elon Musk will become the world’s first modern trillionaire. Due to a wild bull market in Tesla shares over the last two years, the eccentric billionaire’s net worth has skyrocketed to unprecedented heights. Since the beginning of the year 2,020 the price of Tesla stock has risen by more than tenfold.

According to a Morgan Stanley report, the CEO of Tesla will become a trillionaire as a result of the success of his second business, SpaceX.

The private space-exploration company set up by Musk “is challenging any preconceived notion of what was possible and the time frame possible, in terms of rockets, launch vehicles and supporting infrastructure,” wrote Morgan Stanley analyst Adam Jonas in a note titled, ‘SpaceX Escape Velocity … Who Can Catch Them?’

The kidney used in the new procedure was obtained by knocking out a pig gene that encodes a sugar molecule that elicits an aggressive human rejection response. The pig was genetically engineered by Revivicor and approved by the Food and Drug Administration for use as a source for human therapeutics.

Dr. Montgomery and his team also transplanted the pig’s thymus, a gland that is involved in the immune system, in an effort to ward off immune reactions to the kidney.

After attaching the kidney to blood vessels in the upper leg, the surgeons covered it with a protective shield so they could observe it and take tissue samples over the 54-hour study period. Urine and creatinine levels were normal, Dr. Montgomery and his colleagues found, and no signs of rejection were detected during more than two days of observation.

No one knows why some people age worse than others and develop diseases-such as Alzheimer’s, fibrosis, type 2 diabetes or some types of cancer-associated with this aging process. One explanation for this could be the degree of efficiency of each organism’s response to the damage sustained by its cells during its life, which eventually causes them to age. In relation to this, researchers at the Universitat Oberta de Catalunya (UOC) and the University of Leicester (United Kingdom) have developed a new method to remove old cells from tissues, thus slowing down the aging process.

Specifically, they have designed an antibody that acts as a smart bomb able to recognize specific proteins on the surface of these aged or senescent cells. It then attaches itself to them and releases a drug that removes them without affecting the rest, thus minimizing any potential side effects.

The results of this work, which have been published in Scientific Reports, open the door to the development of effective treatments to delay the progress of age-related diseases and even the aging process itself in the longer term, with the aim of increasing the longevity and, above all, the quality of life of people at this stage of their lives.

Brilliant breakdown of a fascinating topic, this.
