Scientists Dive Into Axolotl Genome, Looking for Secrets to Regeneration

mw1fmahs3piturgqptke.jpg

Its adorableness aside, the Mexican axolotl is a salamander of particular interest to scientists. On the molecular level, the animal seems to have a cheat code for life: It can regenerate its limbs and vital organs, an ability researchers are desperate to better understand for medical applications.

Some of Our Brain Cells Get More Active Hours After We Die, Study Finds

gitlcy7w1jciprstiolu.jpg

Even after we die, some of our brain cells can experience one last and large momentary burst of life, new research out Tuesday suggests. The study found evidence that certain “zombie genes” in our brain cells are active more frequently soon after death, which causes some cells to immensely expand for hours. The…

Tiny lab-grown thyroids hint at a new way to treat hypothyroidism

The thyroid, a small butterfly-shaped organ on the front of the throat, produces hormones that are vital for health — and, sadly, the same organ is prone to various issues ranging from autoimmune hypothyroidism to thyroid cancer. Various types of damage and diseases can cause thyroid hormone production to drop, a problem currently treated with synthetic hormones. Though many people … Continue reading

High-Speed 3D Printing Method Could Produce Human Organs In Under an Hour

A 3D printed hand rises from a hydrogel solution.University of Buffalo

Researchers at the University of Buffalo are bringing a science fiction trope to life with their new 3D printing method, which can produce a synthetic hand in under 20 minutes. The rapid printing technology minimizes cellular damage and deformation, making it one of the most viable options for 3D printing human organs.

A surreal YouTube video shows the 3D printing method in action, and it looks like something out of a movie—it’s just so quick and simple. A machine dips into a shallow solution of yellow goo and pulls out a fully-formed synthetic hand in just under 20 minutes. Researchers at the University of Buffalo say that conventional printing methods would take 6 hours to produce the same hand.

The new printing method relies on stereolithography or photo-solidification, the same process used in resin printing. Basically, scientists use light to selectively cure a hydrogel solution into a desired shape. Stereolithography works 10 to 15 times faster than regular bioprinting methods, so scientists can provide a continuous supply of biogel to their model, limiting environmental exposure and mistakes.

Biogel stereolitography is already suited to print cellular models with blood-vessel networks, although the technology is currently limited to centimeter-sized models. Scientists should be able to scale up the method, though, which will be essential for printing human-sized organs. Who knows, in the future, every hospital could be equipped with a biogel stereolithography printer to manufacture replacement organs on the fly, eliminating the need for human-to-human organ transplants.

Experimental brain research makes it seem less likely we’re living in the Matrix

braincomputer-796x417.jpg
The evidence we all exist in base reality – or at least a base reality – is starting to pile up. A team of researchers from the US and the UK recently conducted a groundbreaking study into the neurological conditions of two people living without the sense of touch. Most people orient their conscious existence with the world through a combination of our five senses. We can see a ball flying towards our head, we can feel the ground beneath our feet, we can hear a car whooshing by, and we can smell delicious food before we taste it. The…

3D printers may become standard equipment for operating rooms

Scientists from UNSW Sydney have developed a new ceramic-based ink that could allow surgeons to 3D print bone parts complete with living cells. The 3D printing bone could be used to repair damaged bone tissue during surgery. The 3D printer uses a special ink made of calcium phosphate, and researchers on the project call the ink ceramic omnidirectional bio printing … Continue reading

Microsoft says hackers backed by Russia and North Korea targeted COVID-19 vaccine makers

Microsoft has revealed that hackers backed by Russia and North Korea have targeted pharmaceutical companies involved in the COVID-19 vaccine development efforts.

The technology giant said Friday that the attacks targeted seven companies in the U.S., Canada, France, India, and South Korea. But while it blocked the “majority” of the attacks, Microsoft acknowledged that some were successful.

Microsoft said it had notified the affected companies, but declined to name them.

“We think these attacks are unconscionable and should be condemned by all civilized society,” said Tom Burt, Microsoft’s customer security and trust chief, in a blog post.

The technology giant blamed the attacks on three distinct hacker groups. The Russian group, which Microsoft calls Strontium but is better known as APT28 or Fancy Bear, used password spraying attacks to target their victims, which often involves recycled or reused passwords. Fancy Bear may be best known for its disinformation and hacking operations in the run-up to the 2016 presidential election, but the group has also been blamed for a string of other high-profile attacks against media outlets and businesses.

The other two groups are backed by the North Korean regime, one of which Microsoft calls Zinc but is better known as the Lazarus Group, which used targeted spearphishing emails disguised as recruiters in an effort to steal passwords from their victims. Lazarus was blamed for the Sony hack in 2016 and the WannaCry ransomware attack in 2017, as well as other malware-driven attacks.

But little is known about the other North Korea-backed hacker group, which Microsoft calls Cerium. Microsoft said the group also used targeted spearphishing emails masquerading as representatives from the World Health Organization, charged with coordinating the effort to combat the COVID-19 pandemic.

A Microsoft spokesperson acknowledged it was the first time the company had referenced Cerium, but the company did not offer more.

This is the latest effort by hackers trying to exploit the COVID-19 pandemic for their own goals. Earlier this year, the FBI and Homeland Security warned that hackers would try to steal coronavirus vaccine research.

Today’s news coincides with the Paris Peace Forum, where Microsoft president Brad Smith will urge governments to do more to combat cyberattacks against the healthcare sector, particularly during the pandemic.

“Microsoft is calling on the world’s leaders to affirm that international law protects health care facilities and to take action to enforce the law,” Burt said. “We believe the law should be enforced not just when attacks originate from government agencies but also when they originate from criminal groups that governments enable to operate — or even facilitate — within their borders.”
