By reconstructing ancient nitrogen-processing enzymes, scientists are uncovering new clues about how early life survived on a very different Earth. Nitrogen is essential for life on Earth, yet most organisms cannot use it directly from the atmosphere. Scientists now believe this element may also provide important clues about how life first developed on our planet […]
Resurrected 3.2-Billion-Year-Old Enzyme Could Unlock the Origins of Life
By reconstructing ancient nitrogen-processing enzymes, scientists are uncovering new clues about how early life survived on a very different Earth. Nitrogen is essential for life on Earth, yet most organisms cannot use it directly from the atmosphere. Scientists now believe this element may also provide important clues about how life first developed on our planet […]
Scientists Discover the Brain Chemical That Helps Break Old Habits
A mouse study highlights the role of acetylcholine in behavioral flexibility, offering new insight into the brain mechanisms involved in addiction and obsessive compulsive disorder. Adjusting how we act depending on the situation is essential in everyday life. From professional meetings to personal interactions, success often depends on the ability to change behavior when circumstances […]
Letting Teens Start School Later Boosts Sleep, Health, and Grades
A later school start could help teens sleep more, feel better, and do better in class. Many high school students struggle to fall asleep early enough to get proper rest before school. This is not simply a matter of habits. During adolescence, the body’s internal clock naturally shifts later, making teenagers feel awake later at […]

Scientists Uncover Aging Link That Could Change How Cancer Is Treated
A new study reveals how aging changes the biological behavior of lung cancer. Scientists at the University of Gothenburg have identified a protein that may increase the risk of lung cancer spreading and returning after treatment. Their findings suggest a possible path toward more targeted therapies, especially for older patients. Lung cancer is most common […]
“Harmless” Peptide May Actually Be Linked to Alzheimer’s Disease
Research from UC Santa Cruz indicates that the P3 peptide—an alternative cleavage product of the amyloid precursor protein—may play a role in Alzheimer’s disease. For many years, pharmaceutical companies have focused their Alzheimer’s drug development efforts on amyloid beta, a peptide known for forming sticky deposits in the brain. Billions of dollars and decades of […]
Scientists Take a Major Step Toward Solving the Mystery of the Universe’s Rarest Isotopes
A new experiment using rare-isotope beams has provided new insight into the origin of proton-rich isotopes known as p-nuclei. Researchers have taken an important step toward solving one of astrophysics’ oldest isotope mysteries: where the rare proton-rich atomic species known as p-nuclei come from. The study was led by Artemis Tsantiri, who conducted the work […]

NASA’s Psyche Could Reveal the Secret Inside This Metal World
A massive crater on asteroid Psyche may hold the key to whether it’s a lost planet’s core or something more complex. New simulations suggest NASA’s upcoming mission could finally solve the mystery. More than 200 years after asteroid 16 Psyche was first identified, scientists are still trying to understand how it formed. Psyche is the […]
