Researchers discover a novel cell-to-cell communication network that helps tumors regrow following treatment

In the fight against cancers, activating mutations in the RAS family of genes stand in the way of finding viable treatment options. Now, scientists at the University of Missouri and Yale University have discovered that one of these mutations—oncogenic RAS or RASV12—is also responsible for the regrowth of cancer cells following genotoxic therapy treatment, or drugs that cause damage to […]

A newly discovered circuit helps fish to prioritize

Being constantly flooded by a mass of stimuli, it is impossible for us to react to all of them. The same holds true for a little fish. Which stimuli should it pay attention to and which not? Scientists at the Max Planck Institute of Neurobiology have now deciphered the neuronal circuit that zebrafish use to prioritize visual stimuli. Surrounded by […]

Cleaning up cellular trash helps hearts recover after heart attacks

In a new study, Johns Hopkins Medicine researchers have shown how an enzyme can activate and engage a “trash and recycling system” in heart cells to help patients better recover from a heart attack. The researchers say in their study, published in Nature Communications, that they believe this system could be modified and used to clean up damaged and misfolded […]

Outdated air con helps spread COVID

Most ventilation systems in schools and offices are just not up to the job when it comes to helping curb the spread of COVID-19. That’s the message from a study of how infectious diseases spread in tightly packed buildings using different ventilation systems. Sick building syndrome, which blames factors like heating and air conditioning for sickness, days off and poor […]

Exoskeleton Helps Paralyzed People Walk Again

WEDNESDAY, Nov. 18, 2020 — People paralyzed with spinal cord injuries can safely and effectively use an exoskeleton to assist them in walking, a new study finds. “Participants showed improvement regardless of level of injury, completeness or duration of injury,” said Gail Forrest, director of the Tim and Caroline Reynolds Center for Spinal Stimulation at Kessler Foundation in East Hanover, […]

New ocular device helps administer antioxidants in the eye

Due to their sun and oxygen exposure, the eyes are especially susceptible to oxidative stress, which causes several ocular pathologies. One of the antioxidants that is most present in the eyes to fight oxidative stress is glutathione, the defecit of which is linked to several ophthalmologic diseases. The research group of the CEU UCH of Valencia headed by professor Alicia […]

Machine learning helps grow artificial organs

Researchers from the Moscow Institute of Physics and Technology, Ivannikov Institute for System Programming, and the Harvard Medical School-affiliated Schepens Eye Research Institute have developed a neural network capable of recognizing retinal tissues during the process of their differentiation in a dish. Unlike humans, the algorithm achieves this without the need to modify cells, making the method suitable for growing […]

AI makes dentists’ work easier: New model helps localize the mandibular canals

In order to plan a dental implant operation and the implant size and position, dentists need to know the exact location of the mandibular canal, a canal located in both sides of the lower jaw that contains the alveolar nerve. The lower jaw is an anatomically complex structure and medical experts use X-ray and computer tomography (CT) models to detect […]
