Medical Xpress / Passion fruit–derived molecule shows promise as a future Alzheimer's drug candidate
Four years ago, a research group at the University of Oslo made what would turn out to be a major discovery. They found that an extract from passion fruit had the potential to slow the development of Alzheimer's disease. ...
Medical Xpress / Anthrax‑causing bacteria have dwelled in soil for centuries, cycling through people, animals and earth
The bacteria that cause deadly anthrax disease persist in the earth, a place their ancestors preferred over petri dishes and blood-filled tissues.
Phys.org / Laser-modified graphene enables molecule-thick films to grow only where needed
Researchers from the University of Jyväskylä and Aalto University have developed a new method based on laser modification, which allows metal-organic materials to be grown locally one molecule-thick layer at a time. The ...
Phys.org / Motivations behind violent extremism uncovered in new global study
New research from the University of St Andrews has revealed that human readiness for intergroup violence is not a single or unified mindset. Published in the Proceedings of the National Academy of Sciences, the new study, ...
Medical Xpress / Scientists call out health-harming corporations driving rise in chronic disease
Chronic diseases including cancer, diabetes, neurocognitive disorders and infertility are rising globally, with health-harming products such as fossil fuels, tobacco, ultra-processed foods, toxic chemicals, plastics and alcohol ...
Phys.org / Shell-cracking turtles defied mass extinction at the end of the Cretaceous period
The mass extinction at the boundary between the Cretaceous and Paleogene periods was catastrophic, wiping out much of life on Earth. Vertebrate groups that dominated at the time, such as dinosaurs and many large marine reptiles, ...
Tech Xplore / Dust-resilient perovskite solar cells could cut manufacturing costs and expand green energy worldwide
Research appearing in Communications Materials has shown that perovskite solar cells (PSCs) are remarkably resilient to dust during production, challenging the industry belief that high-performance solar technology must be ...
Phys.org / XRISM clocks hot wind of galaxy M82 at 2 million mph
For the first time, astronomers have directly measured the speed of superheated gas billowing from a cauldron of stellar activity at the heart of M82, a nearby galaxy undergoing an extraordinary burst of star formation. The ...
Phys.org / RNA-guided CRISPR system activates gene expression
In back-to-back studies published in Nature, researchers from Purdue University and Columbia University report a naturally evolved gene-editing system that can activate genes, offering an advantage over existing CRISPR gene-editing ...
Phys.org / Topological solitons power a chip-scale frequency comb source
Caltech scientists have developed a new way to produce optical frequency combs—important tools in devices that keep time and measure distances very precisely—at the chip scale, an advance that should make it easier to ...
Phys.org / Making quantum vibrations nonlinear to enable phonon-phonon interactions
Phonons are the quantum units of mechanical vibration. They describe how motion propagates through a solid at the smallest possible scales, in much the same way that electrons describe electric currents. Because phonons can ...
Phys.org / Extreme global climate outcomes are possible even at 2°C warming, study warns
Extreme climate impacts on people and the environment are often associated with very high levels of global warming (3 or 4°C). A new study led by the Helmholtz Centre for Environmental Research (UFZ) shows that this assumption ...
