Researchers Shocked to Discover Bacterial Parasites Behind Rise of “Superbugs”

Posted by in categories: biotech/medical, evolution, genetics

For the first time ever, researchers from the University of Pittsburgh School of Medicine discovered that phages — tiny viruses that attack bacteria — are key to initiating rapid bacterial evolution leading to the emergence of treatment-resistant “superbugs.” The findings were published today in Science Advances.

The researchers showed that, contrary to a dominant theory in the field of evolutionary microbiology, the process of adaptation and diversification in bacterial colonies doesn’t start from a homogenous clonal population. They were shocked to discover that the cause of much of the early adaptation wasn’t random point mutations. Instead, they found that phages, which we normally think of as bacterial parasites, are what gave the winning strains the evolutionary advantage early on.

“Essentially, a parasite became a weapon,” said senior author Vaughn Cooper, Ph.D., professor of microbiology and molecular genetics at Pitt. “Phages endowed the victors with the means of winning. What killed off more sensitive bugs gave the advantage to others.”

‘Strong Likelihood’ There Are More Dangerous COVID-19 Variants To Come, WHO Warns

Posted by in category: biotech/medical

The COVID-19 pandemic is far from over. In fact, when it comes to the rise of new variants, the worst may still be yet to come.

That’s according to World Health Organization (WHO), who spelled out a strong warning this week to countries hoping to loosen their social distancing measures amidst rising COVID-19 cases and deaths.

“The Committee has expressed concern that the pandemic is being mischaracterized as coming to an end when it is nowhere near finished,” Dr Tedros Adhanom Ghebreyesus, WHO Director-General, said at a media briefing on July 15.

Unconventional superconductor acts the part of a promising quantum computing platform

Posted by in categories: biotech/medical, computing, quantum physics

Scientists on the hunt for an unconventional kind of superconductor have produced the most compelling evidence to date that they’ve found one. In a pair of papers, researchers at the University of Maryland’s (UMD) Quantum Materials Center (QMC) and colleagues have shown that uranium ditelluride (or UTe2 for short) displays many of the hallmarks of a topological superconductor—a material that may unlock new ways to build quantum computers and other futuristic devices.

“Nature can be wicked,” says Johnpierre Paglione, a professor of physics at UMD, the director of QMC and senior author on one of the papers. “There could be other reasons we’re seeing all this wacky stuff, but honestly, in my career, I’ve never seen anything like it.”

All superconductors carry electrical currents without any resistance. It’s kind of their thing. The wiring behind your walls can’t rival this feat, which is one of many reasons that large coils of superconducting wires and not normal copper wires have been used in MRI machines and other scientific equipment for decades.

Report Suggests That Astronauts Shouldn’t get More Than 600 Millisieverts of Radiation Exposure During Their Career. We get 2–3 a Year Down Here on Earth

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

Universe Today.


Space may be pretty, but it’s dangerous. Astronauts face a much higher dose of ionizing radiation than us Earth-bound folks, and a new report says that NASA’s current guidelines and risk assessment methods are in serious need of an update.

On the surface of the Earth, protected by our extensive magnetic field and layers of thick atmosphere, we experience about 2–3 milliSieverts (mSv) of radiation exposure every year. Even that background level is enough to trigger the occasional cancer growth.

Plasma Dilution Potential Benefits & Real Cases Part III | Dr Dobri Kiprov Interview Series

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

Interested in living longer? You are probably going to get TPE at some point. The Conboys are looking for funding for human trials to produce a product in 3–4 years. Here we have infor on what it is and how it works plus actual human results to date (starting at 10 minutes).


In Part III, Dr Kiprov, discusses the history of moving from the Conboy’s experiments in the lab to the process used in the clinic and reasons for the choices made. He also covers the benefits that he has seen with plasma exchange in the clinic.

Advanced care: Smart Wound Dressings with Built-in Healing Sensors

Posted by in categories: biotech/medical, electronics

Fluorescent sensors glow brightly under UV light if infection starts to set in. Researchers have developed smart wound dressings with built-in nanosensors that glow to alert patients when a wound is not healing properly.

The multifunctional, antimicrobial dressings feature fluorescent sensors that glow brightly under UV light if infection starts to set in and can be used to monitor healing progress.

The smart dressings, developed by a team of scientists and engineers at RMIT University in Melbourne, Australia, harness the powerful antibacterial and antifungal properties of magnesium hydroxide.

Repairing hearts with deadly spider venom

Posted by in categories: biotech/medical, life extension

A potentially life-saving treatment for heart attack victims has been discovered from a very unlikely source — the venom of one of the world’s deadliest spiders.

A drug candidate developed from a molecule found in the venom of the Fraser Island (K’gari) funnel web spider can prevent damage caused by a heart attack and extend the life of donor hearts used for organ transplants. The discovery was made by a team led by Dr Nathan Palpant and Professor Glenn King from The University of Queensland (UQ) and Professor Peter Macdonald from the Victor Chang Cardiac Research Institute.

Dr Palpant, from UQ’s Institute for Molecular Bioscience (IMB), said the drug candidate worked by stopping a ‘death signal’ sent from the heart in the wake of an attack.

New artificial intelligence software can compute protein structures in 10 minutes

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

Scientists have waited months for access to highly accurate protein structure prediction since DeepMind presented remarkable progress in this area at the 2020 Critical Assessment of Structure Prediction, or CASP14, conference. The wait is now over.

Researchers at the Institute for Protein Design at the University of Washington School of Medicine in Seattle have largely recreated the performance achieved by DeepMind on this important task. These results will be published online by the journal Science on Thursday, July 15.

Unlike DeepMind, the UW Medicine team’s method, which they dubbed RoseTTAFold, is freely available. Scientists from around the world are now using it to build models to accelerate their own research. Since July, the program has been downloaded from GitHub by over 140 independent research teams.
