Researchers have established that the destruction of ozone over the Arctic in the spring causes abnormal weather throughout the northern hemisphere, with many places being warmer and drier than average — or too wet.

Researchers have discovered why reducing particle pollution is leading to a rise in photochemical smog in some emerging economies such as India, Africa and China.

One often thinks that the early embryo is fragile and needs support. However, at the earliest stages of development, it has the power to feed the future placenta and instructs the uterus so that it can nest. Using ‘blastoids’, in vitro embryo models fo…

An international team has discovered a new big, meat-eating dinosaur, dubbed Meraxes gigas, that provides clues about the evolution and anatomy of predatory dinosaurs such as the Carcharodontosaurus and Tyrannosaurus rex. Meraxes measured around 36 fee…

Barrier islands protect the coastline from storms, storm surge, waves and flooding. They can act as a buffer between the ocean and beachfront property. As sea level rises, barrier islands retreat, or move closer toward the shore, which diminishes the b…

Scientists and physicians describe how wastewater sequencing provided dramatic new insights into levels and variants of SARS-CoV-2 on campus and in the broader community — a key step to public health interventions in advance of COVID-19 case surges.

Researchers announced today that they have built a nanowire that is 2.6 nanometers long, shows an unusual increase in conductance as the wire length increases, and has quasi-metallic properties. Its excellent conductivity holds great promise for the fi…

For more affordable, sustainable drug options than we have today, the medication we take to treat high blood pressure, pain or memory loss may one day come from engineered bacteria, cultured in a vat like yogurt. And thanks to a new bacterial tool, the…

In a new paper, researchers challenge the longstanding view that the force of natural selection in humans must decline to zero once reproduction is complete. They assert that a long post-reproductive lifespan is not just due to recent advancements in h…

After more than a decade of research, scientists share what they have learned about the people who lived on a stretch of coastline in Quintana Roo Mexico over a span of 3,000 years.

MIT Media Lab researchers developed a novel fabrication process to create smart textiles that comfortably and snugly fit the user’s body, enabling very precise pressure sensor data that can be used to analyze and classify the wearer’s postures and moti…

A new study in patients reveals that two newly identified plasma biomarkers of Alzheimer’s disease can predict postoperative delirium, one of the most common postoperative complications in older patients. The findings indicate the potential overlap bet…

Researchers describe a new method to identify all of the unidentified molecules derived from food, providing a direct way to link molecules in diet to health outcomes.

Steel is one of the strongest materials found on earth and is widely used for construction. But on its own, the durability of steel is poor. Galvanizing steel increases its corrosion resistance, making it more sustainable. Recently, a group of scientis…

Russia’s invasion of Ukraine has brought the threat of nuclear warfare to the forefront. But how would modern nuclear detonations impact the world today? A new study published today provides stark information on the global impact of nuclear war.

People with two pediatric-onset neurodevelopmental disorders are prescribed opioids at a rate up to five times higher than those who do not have those conditions, a new study finds. Researchers say the findings raise concerns over addiction, overdose a…

Research has uncovered strong evidence that household overcrowding is a major risk factor for acute rheumatic fever and streptococcal infections of the skin.

Improved understanding of a neural pathway connecting light-sensitive cells in the retina with the cortical brain regions involved in mood and cognition has implications for the development of treatments for mood disorders.

Increases in three climate factors — temperature, rainfall, and ocean warming — predicted mosquito population growth in Sri Lanka for the next one to six months, according to a new study. The findings can inform the design and timing of programs to l…
