Penn Medicine researchers may have found the reason why some patients with advanced chronic lymphocytic leukemia (CLL) don’t respond to chimeric antigen receptor (CAR) T cell therapy, and the answer is tied to how primed patients’ immune systems are before the therapy is administered.
Some bacteria not only escape being killed by bacteria, they turn it into food. Until now, scientists have understood little about how bacteria manage to consume antibiotics safely, but new research from Washington University School of Medicine in St. Louis illuminates key steps in the process. The findings, published April 30 in Nature Chemical Biology, could lead to new ways to eliminate antibiotics from land and water, the researchers said. Environmental antibiotic contamination promotes drug resistance and undermines our ability to treat bacterial infections.
When lava flows down the slope of a volcano, it can leave behind an extreme environment ideal for unusual microbial life and potential clues to answering the life on Mars question. Kansas State University geology professor Saugata Datta is one of the primary investigators of a new NASA study that will use a robotic vehicle to explore and collect data inside caves at Lava Beds National Monument in Northern California.
Researchers from the Saint Louis University School of Medicine have discovered why many multiple myeloma patients experience severe pain when treated with the anticancer drug bortezomib. The study, which will be published April 27 in the Journal of Experimental Medicine, suggests that a drug already approved to treat multiple sclerosis could mitigate this effect, allowing myeloma patients to successfully complete their treatment and relieving the pain of myeloma survivors.

Worse cognitive function in soccer players stems mainly from frequent ball heading rather than unintentional head impacts due to collisions, researchers at Albert Einstein College of Medicine have found. The findings suggest that efforts to reduce long-term brain injuries may be focusing too narrowly on preventing accidental head collisions. The study published online today in the Frontiers in Neurology.

With the help of a $55,000 grant from the National Science Foundation, Kristin O’Donovan, Ph.D., assistant professor of political science in the College of Liberal Arts and Sciences at Wayne State University, will explore the limits on policy learning about disaster mitigation after a community has experienced a disaster. O’Donovan will also seek to understand why one community may be more vulnerable to a disaster than its neighbor.
Cancer immune cell therapy has made headlines with astounding successes like saving former U.S. President Jimmy Carter from brain cancer. But immunotherapy has also had many tragic flops. Georgia Tech researchers working to optimize the innovative treatment have implanted a genetic switch that activates T-cells when they are inside of tumors. Remote-control light waves resembling those used in a TV remote combine with gold nanorods to flip the switch.
A host of nuclear RNA-binding proteins, when misplaced outside the nucleus, form the harmful clumps seen in several brain disorders, including FTD and ALS. Clumps that form from these disease proteins are composed of sticky fibrils that damage nerve cells.
In a groundbreaking paper published today in the journal Cell, investigators at the Cancer Research Institute Beth Israel Deaconess Medical Center (BIDMC) have found dozens of important new genes, both coding and non-coding that impact sensitivity to chemotherapy. In doing so, the scientists developed a novel technique that marries CRISPR technology with big data mining to identify and assign function to non-coding RNAs

Chronic bladder pain affects millions with abdominal discomfort that increases as their bladder fills, causing excessive urinary urgency and frequency. Neuroscientists used optogenetics in experiments with mice to switch on and off the neurons that signal bladder pain.
Scientists have long wondered why the physical traits of Neanderthals, the ancestors of modern humans, differ greatly from today’s man. In particular, researchers have deliberated the factors that necessitated early man’s forward-projecting face and oversized nose. As published in the April 4 edition of The Royal Proceedings Society B, an international research team led by a professor at the University of New England in Australia, with the aid of an anatomy and fluid dynamics expert at NYIT College of Osteopathic Medicine at Arkansas State University (NYITCOM at A-State), may have the answer.

Using computer models and laboratory rats, Johns Hopkins researchers have demonstrated that “direct electrical current” can be delivered to nerves preferentially, blocking pain signals while leaving other sensations undisturbed.
Warmer summer and fall seasons and fewer winter freeze-thaw events have led to changes in the relative numbers of different types of bugs in the Arctic. The study relies on the longest-standing, most comprehensive data set on arctic arthropods in the world today: a catalogue of almost 600,000 flies, wasps, spiders and other creepy-crawlies collected at the Zackenberg field station on the northeast coast of Greenland from 1996-2014.
ROCHESTER, Minn. – A Mayo Clinic study finds no evidence that children given anesthesia before their third birthdays have lower IQs than those who did not have it. A more complex picture emerges among people who had anesthesia several times as small children: Although their intelligence is comparable, they score modestly lower on tests measuring fine motor skills, and their parents are more likely to report behavioral and learning problems. The findings are published in Anesthesiology
