Phys.org / Cyclic catalysts use sunlight and air to regenerate during pharma ingredient synthesis
In chemical processes for producing pharmaceuticals, catalysts are a core technology that determines production speed and cost. However, until now, there has been a trade-off between "precise but disposable catalysts" and ...
Medical Xpress / Therapeutic, nasally delivered DNA vaccine fuses two genes to help fight tuberculosis
In a paper published in the Journal of Clinical Investigation, a research team at Johns Hopkins Medicine and the Johns Hopkins Bloomberg School of Public Health reports developing a therapeutic intranasal (nose-delivered) ...
Medical Xpress / Innovative targeted therapy halts prostate cancer spread to the bone
New findings from VCU Massey Comprehensive Cancer Center and the VCU Institute of Molecular Medicine (VIMM), published in Pharmacological Research, show that an innovative drug effectively prevents prostate tumors from spreading ...
Medical Xpress / Common antidepressant offers fresh hope for people looking to reduce methamphetamine use
For the first time, people who want to stop using crystal methamphetamine may be able to treat their addiction with a cheap and readily available medication, say researchers at the National Drug and Alcohol Research Center ...
Medical Xpress / A safer opioid? DFNZ discovery suggests pain relief with minimal addictive properties
Researchers at the National Institutes of Health (NIH) have identified a novel, highly potent opioid that shows potential as a therapy for both pain and opioid use disorder. In a study published in Nature, the team observed ...
Phys.org / Blood clots, burning eyes: Pollution chokes north Thailand
After hours spent in the thick pollution-choking parts of northern Thailand, Pon Doikam gets home and blows her burning nose to find blood clots spattered across the tissue.
Phys.org / Phosphorus spikes linked to ancient marine mass extinctions
Researchers have uncovered new evidence that short-lived spikes in ocean phosphorus may have played a major role in two of the most severe marine extinctions in Earth's history. Dr. Matthew Dodd from The University of Western ...
Phys.org / Ghost bat dialects emerge across colonies, study suggests
Accents are usually thought of as a human trait, indicating where a person has grown up or the communities they belong—and new research shows the same dialects can also occur in Australia's largest carnivorous bat.
Phys.org / Tasmanian tiger lives on in Arnhem Land rock art
The striped dog-like marsupial we know as the Tasmanian tiger has long been surrounded by mystery, and the subject of scientific curiosity. Now, newly discovered rock art depicting Tasmanian tigers and Tasmanian devils in ...
Phys.org / Forest soil on doormats rebalances urban homes' indoor microbiome, study suggests
Introducing forest soil on an entryway doormat shifted the indoor microbiome of Finnish homes closer to bacterial profiles found outdoors, with less contribution from human-associated bacteria, a new study shows. In the future, ...
Phys.org / Great hammerheads maintain peak hunting across wide temperature swings, biologging data suggest
Most predators slow down when ocean temperatures shift. Great hammerhead sharks don't—not significantly anyway. These ocean predators are masters of the "thermal hustle," maintaining peak hunting performance across a surprisingly ...
Phys.org / Precision work prior to cell division: How enzymes optimize DNA structure
Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the DNA is wrapped around ...
