Major progress in curing brain tumours
2023-05-24
Researchers at the University of Gothenburg, working with French colleagues, have successfully developed a method able to kill the aggressive brain tumour glioblastoma. By blocking certain functions in the cell with a docked molecule, the researchers cause the cancer to die of stress.
Cancer cells, especially those that form aggressive tumours, are in one way or another out of control and live a very stressful existence. To manage this stress, the cancer cells hijack mechanisms that the healthy cells use to regulate protein production and process the surplus proteins that they create. Without these hijacked mechanisms, ...

Study finds school improvement plan (SIP) templates continue to be enacted out of compliance rather than as mechanism for spurring and sustaining improvement efforts in schools
2023-05-24
School accountability policies from around the world list an array of mandates and recommendations to improve schools. One prevalent mandate, especially in the United States, calls for the development of a school improvement plan (SIP). Since the 1970s, many U.S. states have required that schools develop SIPs, and, in the 1990s, the U.S. federal government started to require that all state-designated underperforming schools develop SIPs (IASA, 1994; Odden & Dougherty, 1982). These school accountability policy mandates assert that SIPs are an improvement tool for educators to use to set direction, ...

Biomarkers may help ID treatment of acute kidney injury
2023-05-23
Hospital inpatients who develop an acute kidney injury (AKI) generally fare poorly after being discharged, and have few options for effective treatment.
A UW Medicine-led study published recently in American Journal of Kidney Diseases suggests that new tests might improve this narrative.
In the study, “about 30% of the patients that came into the hospital developed AKI, which means in a matter of hours or days, their kidneys might be failing because of reaction to drugs or contracting sepsis,” said lead author Dr. Pavan Bhatraju, an assistant professor of pulmonary and critical care medicine at the University of Washington School of Medicine.

nTIDE May 2023 Deeper Dive: How did COVID-19 lockdown impact employment of individuals with visual disabilities?
2023-05-23
East Hanover, NJ – May 23, 2023 – New data show that while individuals with visual disabilities were slow to recover employment because of the effects of the COVID-2019 lockdown, they have made headway, depending on their level of disability, almost meeting their pre-pandemic levels. Possible reasons for their slower recovery include major safety concerns due to the shortage of personal protective equipment, less access to vaccines, and their vulnerability to severe consequences of COVID, according to experts speaking during last Friday’s nTIDE Deeper Dive Lunch & Learn Webinar.
Using data from the U.S. Bureau of Labor Statistics (BLS) for persons ages 16-64, the ...
Few adult smokers and nonsmokers think e-cigarettes have lower levels of harmful chemicals than cigarettes
2023-05-23
About half of cigarette smokers and young adult non-smokers think that nicotine-based electronic cigarettes have the same amount or even more harmful chemicals than regular tobacco-based cigarettes, according to a Rutgers study.
The study, published in Addiction, measured perceived levels of harmful chemicals in e-cigarettes compared with cigarettes using national samples of more than 1,000 adults ages 18 and older who smoke cigarettes and 1,000-plus adults ages 18 to 29 who are nonsmokers.

Capturing transporter structure paves the way for drug development
2023-05-23
(Memphis, Tenn.—May 23, 2023) Scientists at St. Jude Children’s Research Hospital and the University of Texas Southwestern Medical Center studied the structure and function of a transporter involved in cancer and immunity. They captured six structures of the transporter, including when it was bound to an inhibitor, providing unprecedented insight into how it works. The findings, published in Cell, have implications for drug development.
Transporters escort substances across the cell membrane so that they can carry out their functions. Sphingosine-1-phosphate (S1P) is an important signaling molecule that regulates the immune system, blood vessel formation, auditory ...
Did dome-headed dinosaurs sport bristly headgear?
2023-05-23
If you look at enough dinosaur fossils, you'll see that their skulls sport an amazing variety of bony ornaments, ranging from the horns of Triceratops and the mohawk-like crests of hadrosaurs to the bumps and knobs covering the head of Tyrannosaurus rex.
But paleontologists are increasingly finding evidence that dinosaurs had even more elaborate head ornaments not preserved with the fossil skulls — structures made of keratin, the stuff of fingernails, that were likely used as visual signals or semaphores to others of their kind.
A newly described species of dome-headed dinosaur — a pachycephalosaur ...
