AI and the transformation of the medical world
Posted by Genevieve Klien in categories: biotech/medical, robotics/AI
Another great advantage is the ability to incorporate AI at early stages of image acquisition. Among other things, this enables us to reduce the amount of radiation needed to acquire a high-resolution CT or shorten the duration needed for an MRI scan. And this leads to patient welfare improvements as well as healthcare cost reductions.
AI applications
In recent years there has been tremendous work in this field mainly focusing on cardiovascular, ophthalmology, neurology, and cancer detection.

Sestrin makes fruit flies live longer

10% longer.
Reduced food intake, known as dietary restriction, leads to a longer lifespan in many animals and can improve health in humans. However, the molecular mechanisms underlying the positive effects of dietary restriction are still unclear. Researchers from the Max Planck Institute for Biology of Aging have now found one possible explanation in fruit flies: they identified a protein named Sestrin that mediates the beneficial effects of dietary restriction. By increasing the amount of Sestrin in flies, researchers were able to extend their lifespan and at the same time these flies were protected against the lifespan-shortening effects of a protein-rich diet. The researchers could further show that Sestrin plays a key role in stem cells in the fly gut thereby improving the health of the fly.
The health benefits of dietary restriction have long been known. Recently, it has become clear that restriction of certain food components, especially proteins and their individual building blocks, the amino acids, is more important for the organism’s response to dietary restriction than general calorie reduction. On the molecular level, one particular well-known signaling pathway, named TOR pathway, is important for longevity.

A good COVID-19 vaccine is one that works for rich and poor alike

And, of course, there is patriarchy. In some parts of the world, women have no control over their health. It is the men – fathers, husbands and uncles – who decide what treatment “their” women receive. Humanitarians have seen men refuse emergency caesareans for their wives. They have also seen them refuse vaccinations for women whose bodies they effectively control.
The Oxford-AstraZeneca vaccine has launched the world on a pro-poor route to fair global vaccination against COVID-19. This is wonderful news. Now we need to address the challenges of a pro-poor roll-out. A major part of this must involve all States getting behind the COVAX effort to ensure fair global access to COVID-19 vaccination tools. It is good to see the UK co-leading on this with others.

Makers of grow-your-own human steaks say meal kit is not ‘technically’ cannibalism
Posted by Raphael Ramos in category: biotech/medical
The saying “You are what you eat” may soon become a lot more literal.
A “DIY meal kit” for growing steaks made from human cells was recently nominated for “design of the year” by the London-based Design Museum.
Named the Ouroboros Steak after the circular symbol of a snake eating itself tail-first, the hypothetical kit would come with everything one needs to use their own cells to grow miniature human meat steaks.

Antiviral method against herpes paves the way for combating incurable viral infections
Posted by Quinn Sena in categories: biotech/medical, genetics
Researchers at Lund University in Sweden have discovered a new method to treat human herpes viruses. The new broad-spectrum method targets physical properties in the genome of the virus rather than viral proteins, which have previously been targeted. The treatment consists of new molecules that penetrate the protein shell of the virus and prevent genes from leaving the virus to infect the cell. It does not lead to resistance and acts independently of mutations in the genome of the virus. The results are published in the journal PLOS Pathogens.
Herpes virus infections are lifelong, with latency periods between recurring reactivations, making treatment difficult. The major challenge lies in the fact that all existing antiviral drugs to treat herpes viruses lead to rapid development of resistance in patients with compromised immune systems where the need for herpes treatment is the greatest (e.g. newborn children, patients with HIV, cancer or who have undergone organ transplantation). Both the molecular and physical properties of a virus determine the course of infection. However, the physical properties have so far received little attention, according to researcher Alex Evilevitch.
“We have a new and unique approach to studying viruses based on their specific physical properties. Our discovery marks a breakthrough in the development of antiviral drugs as it does not target specific viral proteins that can rapidly mutate, causing the development of drug resistance — something that remains unresolved by current antiviral drugs against herpes and other viruses. We hope that our research will contribute to the fight against viral infections that have so far been incurable,” says Alex Evilevitch, Associate Professor and senior lecturer at Lund University who, together with his research team, Virus Biophysics, has published the new findings.

Tesla Model X gets hacked through new relay attack, Tesla says it is pushing a patch
Posted by Genevieve Klien in category: biotech/medical
A hacker managed to develop a new key cloning relay attack for Tesla vehicles and demonstrated it on a Tesla Model X.
Tesla was informed of the new attack and it is reportedly pushing a new patch for it.
Thefts of Tesla vehicles are quite rare in North America, but in Europe, they have some more sophisticated thieves that managed a string of Tesla vehicle thefts through relay attacks, and most vehicles haven’t been recovered.

Doctors say CDC should warn people the side effects from Covid vaccine shots won’t be ‘a walk in the park’
Posted by Quinn Sena in categories: biotech/medical, health
Public health officials and drugmakers must be transparent about the side effects people may experience after getting their first shot of a coronavirus vaccine, doctors urged during a meeting Monday with CDC advisors as states prepare to distribute doses as early as next month.
Dr. Sandra Fryhofer of the American Medical Association noted that both Pfizer’s and Moderna’s Covid-19 vaccines require two doses at varying intervals. As a practicing physician, she said she worries whether her patients will come back for a second dose because of the potentially unpleasant side effects they may experience after the first shot.
