Insulin without needles? Scientists invent gel to deliver insulin through the skin in animal studies
For many people with diabetes, daily insulin injections are required to manage blood sugar levels, but scientists have invented a new polymer-based gel that allows insulin to be administered through the skin without the use of needles. The gel, described in a November study published in Nature, normalized blood sugar levels in diabetic mice and […]
China has planted so many trees around the Taklamakan Desert that this ‘biological vacuum’ has been turned into a carbon sink
Massive tree planting in China is turning one of the world’s largest and driest deserts into a carbon sink. In other words, they absorb more carbon from the atmosphere than they emit, new research shows. The Taklamakan Desert (also spelled Taklamakan or Taklamakan) is slightly larger than the state of Montana, spanning approximately 130,000 square […]

Western Europe’s oldest mule died 2,700 years ago and was buried with a partially cremated woman
About 2,700 years ago, a partially cremated woman buried with a mule is the oldest remains of a hybrid animal ever found in Western Europe, a new study has revealed. The mule and the woman were buried in an ancient rock-lined pit that served as a silo at the Holt den Grimau archaeological site in […]
The 40-year mystery of Uranus’ mysteriously strong radiation may finally be solved
Scientists may have solved a long-standing mystery surrounding Uranus’ unusually strong radiation belts. A new analysis of Voyager 2 data suggests that a temporary space weather event may have made the planet’s electron radiation belts more intense than usual as Voyager 2 passed by. The discovery could help explain why the radiation belt was much […]
Large-scale trial reveals only certain types of brain training reduce dementia risk
Two decades of trials suggest that brain-strengthening exercises that involve quick thinking may reduce the risk of dementia, but exercises that involve memorization or reasoning have no effect on the risk. The discovery could lead researchers to design video games that help users maintain cognitive function as they age, some experts say. As people age, […]
‘Dream engineering’ experiment suggests why ‘sleeping on it’ can help solve problems
In the Hollywood blockbuster Inception (2010), a dedicated team of “dream extractors” is hired to manipulate dreams to change the decisions of CEOs. In the movie, the feat involves a private jet and several liters of sedative gas, but new research suggests a similar effect could have been achieved with just the sound of steel […]
CT scan reveals the final moments of Inca children sacrificed as “messengers of God”
The famous Inca “ice mummies” have remained a secret since their discovery decades ago, but CT scans are beginning to reveal what these children’s final moments were like, a new study has found. Researchers wrote in a study that they examined the bodies of four Incan children who were murdered nearly 500 years ago and […]
Earth’s core contains up to 45 times more hydrogen than the ocean, and research shows it was present early in planetary formation
The Earth’s core contains up to 45 times more hydrogen than the oceans, making it the planet’s largest reservoir of hydrogen, new research suggests. The researchers found that this vast amount of hydrogen entered the core during its formation about 4.5 billion years ago, and did not arrive via a comet that hit Earth after […]
