Iron Nanorobots Go Undercover to Track Living Cells Inside the Body

Customizable magnetic iron nanowires pinpoint and track the movements of target cells.

Living cells inside the body could be placed under surveillance—their location and migration noninvasively tracked in real time over many days—using a new method developed by researchers at KAUST.

The technique uses magnetic core-shell iron nanowires as nontoxic contrast agents, which can be implanted into live cells, lighting up those cells’ location inside a living organism when scanned by magnetic resonance imaging (MRI). The technique could have applications ranging from studying and treating cancer to tracking live-cell medical treatments, such as stem cell therapies.

100-Year-Old Physics Problem Finally Solved – Accurately Predicts Transmission of Infectious Diseases

A Bristol academic has achieved a milestone in statistical/mathematical physics by solving a 100-year-old physics problem – the discrete diffusion equation in finite space.

The long-sought-after solution could be used to accurately predict encounter and transmission probability between individuals in a closed environment, without the need for time-consuming computer simulations.

In his paper, published in Physical Review X, Dr. Luca Giuggioli from the Department of Engineering Mathematics at the University of Bristol describes how to analytically calculate the probability of occupation (in discrete time and discrete space) of a diffusing particle or entity in a confined space – something that until now was only possible computationally.

Post-coronavirus fate differs among Shenzhen tech startups

GUANGZHOU/TOKYO — Tech startups in Shenzhen, known as China’s Silicon Valley, are set to experience a range of outcomes as the novel coronavirus pandemic appears to near its end, with some seeing their businesses thrive while others face headwinds following significantly reduced investment.

AI and robot companies feel positive impact, while some face harsh climate.

Evolution of coronavirus outlines path from animals to humans

Summary: Study reports SARS-CoV-2, the virus that causes COVID-19, was well suited to making the jump from animals to humans by shapeshifting as it gained the ability to infect human cells. The virus’s ability to infect humans occurred via exchanging gene fragments from a coronavirus that infected pangolins. The species-to-species transmission was a result of the ability of SARS-CoV-2 to bind to host cells through alterations to its genetic material.

A team of scientists studying the origin of SARS-CoV-2, the virus that has caused the COVID-19 pandemic, found that it was especially well-suited to jump from animals to humans by shapeshifting as it gained the ability to infect human cells.

The Very First Wormhole Device — For Magnets!

Circa 2015

Physicists have created a wormhole device that can tunnel a magnetic field through space. It sounds like Star Trek, but we won’t be zapping humans across the universe anytime soon. Still, the breakthrough could revolutionize certain magnet-based technologies, including MRIs.

New coronavirus losing potency, top Italian doctor says

ROME (Reuters) — The new coronavirus is losing its potency and has become much less lethal, a senior Italian doctor said on Sunday.

“In reality, the virus clinically no longer exists in Italy,” said Alberto Zangrillo, the head of the San Raffaele Hospital in Milan in the northern region of Lombardy, which has borne the brunt of Italy’s coronavirus contagion.

“The swabs that were performed over the last 10 days showed a viral load in quantitative terms that was absolutely infinitesimal compared to the ones carried out a month or two months ago,” he told RAI television.

Scientists Discover So-Called ‘Skinny Gene’

VIENNA — We all know that one person who can eat whatever they like and never gain a pound. Ice cream at 2 in the morning? Bring it on. A third, or fourth, slice of pizza? Sure, why not. For the rest of us, the genetic perks that these individuals enjoy can be frustrating to say the least. Now, a groundbreaking new international study appears to have zeroed in on the so-called “skinny gene” that help keep such individuals thin.

Scientists from Austria, Canada, and Estonia say that lower, or deficient, levels of the gene Anaplastic Lymphoma Kinase (ALK) are significantly linked to skinniness and bodily resistance to weight gain.

Most research projects focusing on weight loss and gain search for genes that cause obesity. This study is novel due to the fact that it focuses specifically for a gene linked to thinness instead.

A Much-Hyped COVID-19 Drug Is Almost Identical to a Black-Market Cat Cure

A tale of GS-441524, the remdesivir sister drug that cures coronavirus (FIP) in cats, but that Gilead refused to develop for fear it would mess up the approval process of remdesivir.

Yes, it a tale of capitalism on steroids, and the FDA on drugs. It’s the kind of thing that may well kill you and your family, but you will never know about it (unless you read about it in The Atlantic, or some obscure journal).

Cat owners are resorting to China’s underground marketplace to buy antivirals for a feline coronavirus.
