There may be renewed hope for people with untreatable cancers. According to a report published by the BBC on Friday, patients have had their immune system…

Watch a virus in the moments right before it attacks
When Courtney “CJ” Johnson pulls up footage from her Ph.D. dissertation, it’s like she’s watching an attempted break-in on a home security camera.
The intruder cases its target without setting a foot inside, looking for a point of entry. But this intruder is not your typical burglar. It’s a virus.
Filmed over two and a half minutes by pinpointing its location 1,000 times a second, the footage shows a tiny virus particle, thousands of times smaller than a grain of sand, as it lurches and bobs among tightly packed human intestinal cells.
Machine learning of binary ‘yes/no’ systems may improve medical diagnoses, financial risk analysis, and more
Similar to a mouse racing through a maze, making “yes” or “no” decisions at every intersection, researchers have developed a way for machines to swiftly learn all the twists and turns in a complex data system.
“Our method may help improve the diagnosis of urinary diseases, the imaging of cardiac conditions and analysis of financial risks,” reported Abd-AlRahman Rasheed AlMomani of Embry-Riddle Aeronautical University’s Prescott, Arizona, campus.
The research was accepted for the Nov. 11 edition of the journal Patterns with Jie Sun and Erik Bollt of Clarkson University’s Center for Complex Systems Science. The goal of the work is to more efficiently analyze binary (“Boolean”) data.
New Drug Reverses Neural and Cognitive Effects of a Concussion
ISRIB, a tiny molecule identified by University of California, San Francisco (UCSF) researchers can repair the neural and cognitive effects of concussion in mice weeks after the damage, according to a new study.
ISRIB blocks the integrated stress response (ISR), a quality control process for protein production that, when activated chronically, can be harmful to cells.
The study, which was recently published in the Proceedings of the National Academy of Sciences, discovered that ISRIB reverses the effects of traumatic brain injury (TBI) on dendritic spines, an area of neurons vital to cognition. The drug-treated mice also showed sustained improvements in working memory.
In a first, doctors treated a fatal genetic disease before birth
A toddler is thriving after doctors in the U.S. and Canada used a novel technique to treat her before she was born for a rare genetic disease that caused the deaths of two of her sisters.
Ayla Bashir, a 16-month-old from Ottawa, Ontario, is the first child treated as a fetus for Pompe disease, an inherited and often fatal disorder in which the body fails to make some or all of a crucial protein.
