Scientists say evolution may work differently than we thought

For decades, many evolutionary biologists have viewed much of molecular evolution as surprisingly quiet. The idea was that many of the genetic changes that spread through populations are neither helpful nor harmful. They simply drift through nature without attracting much attention from natural selection. A University of Michigan study challenges…

A silent kidney crisis is spreading far faster than experts expected

Chronic kidney disease has become one of the world’s most widespread and deadly health problems, with record numbers of people now estimated to have reduced kidney function. A 2025 global analysis found that the number of people living with the condition rose from 378 million in 1990 to 788 million…

Twisted graphene reveals a hidden superconductivity switch

Researchers have uncovered evidence that superconductivity can be controlled by changing a material’s surrounding environment, a breakthrough that could eventually lead to more efficient electronics and powerful quantum technologies. Superconductivity allows certain materials to carry electricity with zero energy loss when cooled below a critical temperature. Even though scientists have…

Rogue planet moons could harbor alien life for billions of years

Liquid water is widely considered one of the key ingredients for life. But new research suggests that worlds drifting through the darkness of interstellar space could still remain habitable, even without the warmth of a nearby star. A team of scientists from the Excellence Cluster ORIGINS at Ludwig Maximilian University…

Antarctica’s ice sheet hit a climate tipping point 1 million years ago

A new study published in Nature Geoscience suggests Antarctica’s ice sheet underwent a dramatic change about one million years ago, becoming much more responsive to shifts in Earth’s climate. The research, led by scientists at the IBS Center for Climate Physics (ICCP) at Pusan National University in South Korea, offers…

Vitamin B12 and folate deficiencies linked to chronic fatigue

Chronic fatigue has become increasingly common in modern life as people juggle heavier workloads and less downtime. While exhaustion is often blamed on stress or lack of sleep, researchers say poor nutrition may also play an important role. A research team led by Professor Hiroaki Kanouchi from Osaka Metropolitan University’s…

Human organoids reveal how to reverse “irreversible” nerve damage

Scientists at the University of Cambridge have created tiny lab-grown brain and spinal cord systems that mimic how movement signals travel through the human nervous system. Using this model, the team discovered that nerve damage once believed to be permanent may actually be reversible under certain conditions. As the human…

CBD may slow Alzheimer’s by calming the brain’s immune system

Cannabidiol, better known as CBD, is gaining attention from scientists studying Alzheimer’s disease. New research suggests the cannabis-derived compound may help reduce harmful inflammation in the brain, a process increasingly believed to play a major role in Alzheimer’s progression. Alzheimer’s disease is the most common form of dementia, a condition…

Eurispes, tra affitto e cure mediche, l’Italia è fragile – Notizie – Ansa.it

Una situazione economica, nel nostro Paese, avvertita come “in peggioramento” per il 47,8% dei cittadini nei prossimi dodici mesi. Le maggiori difficoltà economiche ruotano intorno al pagamento del canone d’affitto, che mette in difficoltà il 45,6% delle famiglie e, tra le conseguenze, impone anche rinunce alle cure mediche. Il 38esimo…
