Hand-sanitizer resistant bacteria strains are developing

Posted by in category: biotech/medical

With hand sanitizer being one of the top sellers on the market since Covid-19 I wonder how quickly these bugs will turn into superbugs?


How worried should we be about bacteria with an alcohol tolerance? Be afraid, be very afraid.

SoftBank eyes smaller bets, bigger returns in Vision Fund rethink

Posted by in categories: biotech/medical, education, finance, government, health, wearables

The quiet shift in strategy, which brings the Vision Fund’s approach closer to that of a traditional venture capital investor, may ease concerns over big, bold bets going sour, a factor that has left a major gap between SoftBank’s market capitalization and the sum of its investments.


TOKYO — SoftBank Group’s Vision Fund is turning to a new strategy as a global pandemic and government stimulus distort tech valuations: Invest smaller in hopes for bigger returns.

After raising nearly $100 billion and investing $85 billion in high-profile companies like Uber Technologies, WeWork and ByteDance over three years, the Vision Fund is now focusing on making smaller bets in early-stage startups.

Medical drones take flight in the Netherlands for the first time

Posted by in categories: biotech/medical, drones

Over the next few months, medical delivery drones will take flight in the Netherlands between two hospitals to deliver emergency medicines, blood, and other time-sensitive samples. The drones will be flying between the Isala Diaconessenhuis Meppel hospital and the Isala Ziekenhuis hospital.

The drones are at the center of tests, looking at how they can deliver emergency medicine in the future and improve patient care. This also marks the first time drones have flown beyond visual line of sight (BVLOS) in overpopulated areas.

The tests are being run by the Medical Drone Service, an initiative set up by ANWB, PostNL, Erasmus MC, Isala, Sanquin, Certe, and technology partners Avy and KPN.

Pfizer’s announcement shows the promise of gene-based vaccines

Posted by in category: biotech/medical

Pfizer’s COVID-19 vaccine uses a gene-based platform that hasn’t been used for approved human vaccines. The reported high efficacy is a good sign for other vaccines using that approach.

Researchers create MRI-like technique for imaging magnetic waves

Posted by in categories: biotech/medical, computing, health, nanotechnology

A team of researchers from Delft University of Technology (TU Delft), Leiden University, Tohoku University and the Max Planck Institute for the Structure and Dynamics of Matter has developed a new type of MRI scanner that can image waves in ultrathin magnets. Unlike electrical currents, these so-called spin waves produce little heat, making them promising signal carriers for future green ICT applications.

MRI scanners can look into the human body in a non-invasive manner. The scanner detects the magnetic fields radiated by the atoms inside, which makes it possible to study the health of organs even though they are hidden underneath thick layers of tissue.

The non-invasive, see-through power of MRI is desirable for many research fields and industries. It could be particularly useful as an imaging tool in nanotechnology and the chip industry. Being able to detect signals in computer chips and other nanodevices would facilitate optimizing their performance and reducing their heat production. However, the millimeter resolution of conventional MRI is insufficient to study chip-scale devices. A team of researchers led by TU Delft have now developed a new method for sensing at the sub-micrometer scale.

Why Children Need To Learn About Artificial Intelligence

Posted by in categories: biotech/medical, ethics, robotics/AI

It has been really fun talking to the kids about AI. Should we help AI consciousness to emerge — or should we try to prevent it? Can you design a kindest AI? Can we use AI as an universal emotion translator? How to search for an AI civilization? And many many other questions that you can discuss with kids.


Ultimately, early introduction of AI is not limited to formal instruction. Just contemplating future scenarios of AI evolution provides plentiful material for engaging students with the subject. A survey on the future of AI, administered by the Future of Life Institute, is a great starting point for such discussions. Social studies classes, as well as school debate and philosophy clubs, could also launch a dialogue on AI ethics – an AI nurse selecting a medicine, an AI judge deciding on a criminal case, or an AI driverless car switching lanes to avoid collision.

Demystifying AI for our children in all its complexity while providing them with an early insight into its promises and perils will make them confident in their ability to understand and control this incredible technology, as it is bound to develop rapidly within their lifetimes.

Age is decisive for positive or negative effects of the diabetes drug metformin

Posted by in categories: biotech/medical, life extension, neuroscience

“In our current study we were able to uncover important limitations for the use of metformin as longevity medicine,” says Dr. Ermolaeva. In contrast to the positive longevity effects in young organisms that received metformin, lifespan is shortened through metformin intake at an older age. “Previous studies that provided evidence of an extended longevity by metformin usually examined animals treated with metformin from young adult or middle age until the end of life. In contrast, we have looked at treatment windows covering the entire life span, or restricted to early life or to late life”. The study also utilized a human cell culture model of replicative aging to assess human responses to metformin at a cellular level and compare them to organismal responses of the worms.

**Metformin longevity benefits are reversed with age**

The research team led by Dr. Ermolaeva found that the very same metformin treatment that prolonged life when C. elegans worms were treated at young age, was highly toxic when animals of old age were treated. Up to 80% of the population treated at old age were killed by metformin within the first 24 hours of treatment. Consistently, human primary cells demonstrated a progressive decrease in metformin tolerance as they approached replicative senescence. The researchers were able to link this detrimental phenotype to the reduced ability of old cells and old nematodes to adapt to metabolic stressors like metformin. Under these circumstances, the exact same dose of the drug that increased longevity of young-treated organisms by triggering adaptive stress responses was harmful in animals treated at old age, which were unable to activate such protective signals.
