Phys.org / A new way to replace carbon with nitrogen atoms could lead to better medicines
When drugmakers want to improve on compounds they have already created, they can replace a carbon atom with a nitrogen atom. While effective, the techniques they use to perform this chemical swap, known as skeletal editing, ...
Phys.org / Candida auris copies its entire genome to survive antifungal treatment, research reveals
New research has revealed an unexpected new mechanism through which the killer fungus Candida auris is resisting antifungal drug treatment. A team led by the University of Exeter and City St George's, University of London, ...
Medical Xpress / Napping linked to dementia risk
Your napping habits might be a warning flag for dementia, a new study says.
Phys.org / Plants use a molecular measuring tape to tell fungal friend from foe
Chitin, a chain of repeating sugar molecules, is the main building block of fungal cell walls. When fungi grow or are broken down, fragments of chitin chains of different lengths end up in the soil, and plants detect them ...
Phys.org / Newly discovered 3D 'chair' shape can fill all space without repeating patterns
Software developer Ioannis Tsiokos has reported the discovery of a three-dimensional shape, which roughly resembles a chair, that can fill space infinitely without repeating a pattern. The shape follows certain mathematical ...
Medical Xpress / AI misuse and nuclear famine could threaten humanity's survival before 2100
The fate of global health does not rest on any single disease. True preparedness means pairing the fight against illness with strength in finance, climate, defense and security. The COVID-19 pandemic, which brought the world ...
Phys.org / Vera Rubin Observatory spots the largest ultra-fast spinning asteroid yet
The speed of an asteroid's spin can tell astronomers a surprising amount about what it is made of. However, existing approaches to measuring spin based on telescope observations can often produce misleading estimates.
Medical Xpress / Brain PET scans help select and monitor patients for new Alzheimer's drugs
Nuclear medicine is playing an increasingly important role in the diagnosis and treatment of Alzheimer's disease, helping clinicians visualize the biological changes associated with the condition and guide decisions about ...
Phys.org / Political violence: How justifications influence voter approval
What happens when political violence is presented as a justified response to threat or injustice coming from an out-group? A study by Ursula Daxecker, director at the Max Planck Institute for Politics and Social Science in ...
Phys.org / In animated films, nonhuman characters are still overwhelmingly male
Female protagonists in animated films have come a long way over the past several decades. Take the 1959 movie "Sleeping Beauty": Soft-spoken and vulnerable, Princess Aurora is cursed as an infant by the evil fairy Maleficent ...
Phys.org / Measuring deep-ocean oxygen with microscopic magnetic fossils
Humanity's ongoing disruption of atmospheric carbon dioxide (CO₂) concentrations, temperatures, and global nutrient cycles is starving the oceans of oxygen. Although we can measure ongoing changes to ocean circulation and ...
Medical Xpress / Light-activated opioid painkiller may work without dangerous side effects
Opioid painkillers are some of the strongest analgesic medicines, but they are also the riskiest owing to a range of side effects, including addiction. An experimental opioid painkiller designed to be reversibly switched ...
