Phys.org / PFAS concentrations can double with every step up the food chain
A new UNSW-led global meta-analysis shows that PFAS concentrations can double at every step up the food chain, leaving top predators—and humans—potentially exposed to higher chemical loads.
Phys.org / Leaves' pores explain longstanding mystery of uneven tree growth in a carbon-enriched world
The basics of photosynthesis are something that every student learns in school: carbon dioxide, water and light in; oxygen and sugar for growth out. In a world where atmospheric carbon dioxide levels are rising, it is plausible ...
Phys.org / Artificial metabolism turns waste CO₂ into useful chemicals
In a breakthrough that defies nature, Northwestern University and Stanford University synthetic biologists have created a new artificial metabolism that transforms waste carbon dioxide (CO2) into useful biological building ...
Phys.org / Ancient sea anemone sheds light on animal cell type evolution
One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A neuron doesn't look nor behave ...
Medical Xpress / Patient education can reduce preference for antibiotics for asymptomatic bacteriuria
Receipt of a patient-centered educational leaflet decreases the desire to take antibiotics for asymptomatic bacteriuria (ASB), according to a study published in the December issue of Open Forum Infectious Diseases.
Phys.org / East Antarctic Ice Sheet's history tells a relevant story for today and beyond
Though ice sheet melting is widely talked of and debated, there is limited knowledge about what happens after the period of melting. Researchers dig into this "after" period and see how it relates to previous patterns.
Medical Xpress / Intractable intestinal disease treatment: Xenogeneic-free polymer platform shows promise
Intestinal stem cells (ISCs) derived from a patient's own cells have garnered significant attention as a new alternative for treating intractable intestinal diseases due to their low risk of rejection. However, clinical application ...
Medical Xpress / Mental health conditions linked to higher risk of unintentional injury
People with mental health conditions face a significantly higher risk of physical injuries, according to a new University of Michigan study.
Medical Xpress / Clearing the brain of aging cells could aid epilepsy and reduce seizures
Temporal lobe epilepsy, which results in recurring seizures and cognitive dysfunction, is associated with premature aging of brain cells.
Phys.org / Why we sometimes avoid the truth and other times can't stop looking for it
A new study by Prof. Yaniv Shani of the Coller School of Management at Tel Aviv University and Prof. Marcel Zeelenberg of the Tilburg School of Social and Behavioral Sciences reveals a surprising insight into how we deal ...
Medical Xpress / Key phospholipid points to potential treatment for vascular dementia
A possible new treatment for impaired brain blood flow and related dementias is on the horizon. Research by scientists at the University of Vermont Robert Larner, M.D. College of Medicine provides novel insights into the ...
Phys.org / Russia's plans for a space station include 'recycling' its ISS modules
With the International Space Station (ISS) set to retire in 2030, several nations and commercial space companies have plans to deploy their own successor stations. This includes China, which plans to double the size of its ...
