A new approach reveals unexpected ways oxygen can bind to rare metals. Iron plays a central role in how the body uses oxygen. In hemoglobin, it binds dioxygen, a pair of oxygen atoms, allowing blood to carry oxygen to tissues. But this is only part of the story. Iron-oxo compounds, which contain iron bonded to […]
A New Chapter in Chemistry? Scientists Uncover New Way Metals Bind Oxygen

New Study Reveals Earth Is Getting Brighter at Night – About 2% Each Year
Satellite observations reveal that global nighttime lighting is steadily rising, though the trend varies widely by region, with some areas brightening rapidly while others dim. An analysis of data from the VIIRS Day/Night Band satellite instrument, covering 2014 through 2022, shows that artificial lighting at night is increasing worldwide by about 2 percent each year. […]

Cooling the Planet Could Come at a Devastating Cost
Efforts to cool the planet may do more than lower temperatures, they could fundamentally reshape Earth’s climate systems. As carbon dioxide emissions continue to rise, more policymakers, scientists, and environmental advocates are exploring geoengineering as a potential way to limit climate change. These large-scale interventions could affect everything from rainfall patterns to global food production, […]
These New Molecules Could Change How We Treat Lupus and Arthritis
Researchers have identified a promising new strategy to treat autoimmune diseases by targeting a specific molecular interaction within immune cells. Scripps Research scientists have created a new group of drug compounds that reduce harmful inflammation without weakening the body’s ability to fight infections, a major challenge in treating autoimmune diseases. These compounds, known as ENDOtollins, […]

Saunas May Do More Than Raise Body Temperature – They Activate Your Immune System
A brief sauna session may quietly mobilize the immune system. A sauna session may do more than raise your heart rate and body temperature. A new study from Finland found that it also briefly increases the number of white blood cells moving through the bloodstream, a shift tied to the body’s frontline immune defenses. The […]
Exercise in a Pill? Metformin Shows Surprising Effects in Cancer Patients
Researchers have identified a surprising metabolic effect of a widely used diabetes drug in men undergoing prostate cancer treatment. A new study suggests that metformin, a commonly prescribed drug for diabetes, may reproduce a key biological effect of exercise in men with prostate cancer. Researchers found that the medication increases levels of a molecule linked […]
Saturn’s Magnetic Shield Isn’t What Scientists Expected
Saturn’s magnetic shield behaves in a way that defies Earth-based expectations. Scientists analyzing data from the Cassini-Huygens mission have identified an unexpected feature in Saturn’s magnetic shield. According to the team, the finding shows that giant planets follow a different set of rules than Earth when it comes to how their magnetospheres behave. The study, […]
