A new study led by the University of Kansas might resolve a mystery in the “aging process” in species — or, how a species’ risk of going extinct changes after that species appears on the scene. For years, evolutionary biologists believed older species lacked any real advantage over younger ones in avoiding extinction — an idea known as “Red [...]
A decades-old mystery of how natural antimicrobial predatory bacteria are able to recognize and kill other bacteria may have been solved, according to new research. In a study published in Nature Microbiology, researchers from the University of Birmingham and the University of Nottingham have discovered how natural antimicrobial predatory bacteria, called Bdellovibrio bacterivorous, produce fiber-like proteins on their surface to [...]
Scientists are investigating whether an oral drug sprinkled with gold nanoparticles could one day treat neurodegenerative diseases like Parkinson's and multiple sclerosis. The experimental medicine, called CNM-Au8, has now shown success in boosting the brain's metabolism in phase II clinical trials. Research on the safety and efficacy of the daily drug is still ongoing, [...]
Scientists are a step closer to unraveling the mysterious forces of the universe after working out how to measure gravity on a microscopic level. Experts have never fully understood how the force that was discovered by Isaac Newton works in the tiny quantum world. Even Einstein was baffled by quantum gravity and, in his [...]
Recent research reveals a breakthrough in lung repair, showing how delivering VEGFA via lipid nanoparticles can significantly repair damaged blood vessels, akin to plumbing repairs. This method, validated in animal models, offers promising insights into treating respiratory virus damages, enhancing oxygen delivery, and reducing lung inflammation and scarring. In the human body, the lungs and their [...]
Researchers from the University of Illinois Chicago and Harvard University have created an antibiotic that may provide medicine a new tool to combat bacteria resistant to drugs and the illnesses they trigger. The antibiotic, cresomycin, described in Science, effectively suppresses pathogenic bacteria that have become resistant to many commonly prescribed antimicrobial drugs. The promising novel antibiotic is the latest [...]
Elon Musk has claimed the first human patient implanted with his wireless Neuralink brain chip can move a computer cursor ‘just by thinking’. ‘Progress is good, and the patient seems to have made a full recovery, with neural effects that we are aware of,’ Musk said in a Spaces event X. ‘Patient is able to move [...]
Vaccines that protect against severe illness, death and lingering long Covid symptoms from a coronavirus infection were linked to small increases in neurological, blood, and heart-related conditions in the largest global vaccine safety study to date. The rare events — identified early in the pandemic — included a higher risk of heart-related inflammation from mRNA shots made by Pfizer Inc., BioNTech SE, and Moderna Inc., and an [...]
Scientists propose a new model for classifying Parkinson’s. The complexity of Parkinson’s disease poses significant challenges in developing effective treatments. This complexity stems from various causes, including genetics and environmental factors, coupled with the broad spectrum of symptoms that patients may experience, which can vary greatly in severity. Additionally, the diagnosis of Parkinson’s often [...]
A revolutionary nanomaterial with huge potential to tackle multiple global challenges could be developed further without acute risk to human health, research suggests. The study is published in the journal Nature Nanotechnology. Carefully controlled inhalation of a specific type of graphene—the world's thinnest, super strong and super flexible material—has no short-term adverse effects on lung or cardiovascular function, [...]
