Phys.org / Enzyme disables bacterial toxin by cleaving key chemical ring structure
A research team at Leibniz-HKI has described a new enzyme that renders the highly toxic molecule malleicyprol harmless. Malleicyprol is considered an important virulence factor of Burkholderia bacteria, which causes, among ...
Medical Xpress / Promising target improves antitumor response in preclinical models of pancreatic cancer
Researchers at The University of Texas MD Anderson Cancer Center have found that a mitochondrial enzyme, GFER, creates an immunosuppressive environment within pancreatic tumors, leading to treatment resistance.
Phys.org / Drone-mounted lab monitors fertilizer runoff in real time
What if, instead of taking a water or soil sample to the lab, you could take the lab to the sample? That's what a team of researchers reporting in ACS Sensors did with a new nitrate-monitoring "lab-on-a-drone" system. The ...
Tech Xplore / Confined crystallization strategy improves spray-coated perovskite device performance
Metal halide perovskites are promising for next-generation high-efficiency photovoltaic and optoelectronic devices due to excellent tunable properties and solution processability. Recent fabrication techniques (such as spin ...
Phys.org / How misreading Google Trends is fueling Bondi attack conspiracy theories
In the wake of Sunday's tragic Bondi shooting, conspiracy theories and deliberate misinformation have spread on social media.
Phys.org / Accelerating next-generation drug discovery with click-based construction of PROTACs
In 2001, chemists K. Barry Sharpless, Hartmuth C. Kolb, and M. G. Finn introduced click chemistry, a concept in which organic molecules can be rapidly and reliably joined to form more complex structures. They recognized that ...
Phys.org / Altermagnetism in RuO₂ thin films: A new magnetic material for the AI era
A research team has demonstrated that thin films of ruthenium dioxide (RuO₂) exhibit altermagnetism—the defining property of what is now recognized as the third fundamental class of magnetic materials.
Phys.org / Young shark species more vulnerable to extinction, fossil record reveals
Whether a species has just freshly emerged, or it has been around for millions of years does not dictate its vulnerability. This has been the assumption of an old debate on whether species' age plays a role in extinction ...
Tech Xplore / Why it's so hard to tell if a piece of text was written by AI, even for AI
People and institutions are grappling with the consequences of AI-written text. Teachers want to know whether students' work reflects their own understanding; consumers want to know whether an advertisement was written by ...
Medical Xpress / Fee-based primary care is rapidly rising in US, hastening doctor shortages for the public
The number of concierge and direct primary care practices are rapidly rising across the United States, highlighting a fundamental shift in how Americans are receiving primary medical care, a new study finds.
Medical Xpress / HPV vaccine can protect against severe lesions of the vulva and vagina, study finds
Girls who are vaccinated against HPV are not only well protected against cervical cancer; they are also less likely to develop severe precancerous lesions of the vulva and vagina, particularly if they were vaccinated before ...
Phys.org / Italian bears living near villages have evolved to be smaller and less aggressive, finds study
A paper in Molecular Biology and Evolution, reports that Italian bears living in areas with many villages evolved and became smaller and less aggressive.
