Scientists discover hidden water beneath Mars that could have supported life

Researchers at New York University Abu Dhabi (NYUAD) have discovered new clues suggesting that water once moved beneath the surface of Mars. The findings indicate that the Red Planet may have remained capable of supporting life for much longer than scientists once believed. The research, published in the Journal of…

Scientists tested vitamin D for COVID and found an unexpected long COVID clue

Findings from a large study led by Mass General Brigham suggest scientists should continue investigating whether vitamin D supplements could influence long COVID. The research showed that taking high doses of vitamin D3 did not make COVID-19 infections less severe, but it may have a possible connection to long COVID…

The financial crisis that quietly stunted a generation

Sharp increases in food prices during economic crises tend to hit certain groups the hardest. Urban residents and families with lower levels of education are often especially vulnerable. These price shocks can lead to long term health problems, including stunted growth in children. Researchers at the University of Bonn recently…

Crops irrigated with wastewater store drugs in their leaves

In regions where freshwater supplies are limited, farmers sometimes rely on treated wastewater to water their crops. While this practice helps conserve scarce water resources, it has raised concerns among regulators and consumers. Wastewater can contain trace amounts of various substances, including psychoactive medications commonly used to treat mental health…

Fathers’ tobacco use linked to metabolic changes in their children

New research published in the Journal of the Endocrine Society suggests that a father’s nicotine exposure could influence how his offspring process sugar. In a mouse study, scientists found that paternal nicotine intake led to metabolic changes in the next generation. These alterations may affect how the body handles glucose…

Scientists discover ALS protein that links DNA repair to cancer and dementia

Researchers at Houston Methodist have discovered that a protein tied to neurodegenerative conditions such as dementia and amyotrophic lateral sclerosis (ALS) also helps control a critical DNA repair process. This repair system, known as DNA mismatch repair, corrects mistakes that occur when cells copy genetic material. The discovery suggests that…

Hidden deep-sea proteins could supercharge disease tests

Researchers have identified previously unknown DNA-binding proteins in some of the most extreme places on Earth and demonstrated that they can enhance rapid medical tests used to detect infectious diseases. The international team was led by Durham University and included collaborators in Iceland, Norway, and Poland. The scientists examined genetic…

A donut-shaped protein breaks apart to start bacterial cell division

A research team led by Universitat Autònoma de Barcelona (UAB) scientist David Reverter has identified the molecular mechanism that regulates bacterial cell division. The discovery reveals how the MraZ protein binds to the dcw gene cluster to control this process. The findings were published in Nature Communications. Cell division is…

NASA’s Curiosity rover investigates strange spiderweb ridges on Mars

A rugged Martian landscape that resembles a giant spiderweb when seen from orbit may hold important evidence about the history of water on ancient Mars. For roughly six months, NASA’s Curiosity rover has been studying an area covered with geological features known as boxwork. These formations appear as narrow ridges…

Scared of spiders? Scientists say the real nightmare is losing them

Members of the arachnid class — think spiders, scorpions and harvestmen (daddy long legs) — often trigger feelings of fear or disgust. Despite this reaction, these animals play an essential role in maintaining healthy ecosystems. As global biodiversity declines, including what some researchers describe as an “insect apocalypse,” two ecologists…

La rivincita di Powell: ‘Trump voleva piegarlo alla sua volontà’ – Notizie – Ansa.it
