Scientists cured type 1 diabetes in mice by creating a mixed immune system
Scientists cured type 1 diabetes in mice without causing long-term immunosuppression. Type 1 diabetes has historically required lifelong doses of powerful immunosuppressive drugs for the immune system to attack insulin-producing cells and replace them with transplanted cells from a donor, severely limiting the scope of such transplants. But in a new study, researchers created a […]
Native Americans invented dice and games of chance more than 12,000 years ago, archaeological research reveals
Native American tribes in the western United States invented dice more than 12,000 years ago, providing archaeologists with the world’s earliest evidence of gambling and perhaps the earliest use of probability, a new study finds. However, the purpose of these games of chance was very different from modern gambling: the games helped people (mostly women, […]
Artemis II launches: humans are returning to the moon
The Artemis II crew departed for the moon in a historic rocket launch at NASA’s Kennedy Space Center in Florida. Captain Reed Wiseman, pilot Victor Glover, mission specialist Christina Koch, and mission specialist Jeremy Hansen are currently aboard the Orion spacecraft, becoming the first humans to return to the moon in more than 50 years. […]
Astronauts could be exposed to “nearly lethal doses” of sunlight – so why launch Artemis II at peak solar activity? Space scientist Patricia Leaf explains.
The Artemis II astronauts are about to take off on a record-breaking flight around the moon, giving NASA a rare opportunity to study how deep space flight affects the human body. After leaving Earth’s protective magnetic field, the four-person crew will be exposed to space weather, including bursts of high-energy radiation from the Sun known […]
Hubble photos reveal that Fart Comet has reversed its rotation for the first time in history and may soon explode on its own.
Thanks to newly analyzed Hubble Space Telescope photos, astronomers have, for the first time in history, witnessed a comet change the speed and direction of its rotation. A new study says the unexpected reversal was caused by an “outgassing” jet that injected an icy mixture of gas and dust into the solar system. The comet, […]
Diagnostic dilemma: Teenager’s hives turned out to be caused by rare water allergy
Patient: A teenage girl living in Canada. Symptoms: This teenage girl comes to the clinic because her hives recur every time her skin comes into contact with water. When she visited the clinic, she was suffering from hives. The inflamed bump was surrounded by red patches of skin about 0.4 to 1.2 inches (1 to […]
China’s massive push to reduce air pollution has unintended consequences for the Arctic
China’s significant reductions in air pollution may have brought unexpected benefits to the Arctic. A new study shows that aerosol-driven storms have decreased, resulting in less sea ice loss. But at the same time, experts say this drastic drop in aerosols may have accelerated global warming. “The Chinese people have been suffering from poor air […]
Scientists discover deadly superbug’s Achilles heel and how to exploit it
Antibiotic-resistant bacteria may have an Achilles heel. The Achilles heel is a unique sugar molecule that exists only on the outside of bacterial cells. Recent studies in mice have shown that targeting this molecule can make bacteria more vulnerable to the immune system, which can destroy them and clear infections. If the same effect can […]
Quantum computers need just 10,000 qubits to crack the most secure codes, scientists warn
Quantum computers don’t need to be as powerful as we think to break the world’s most secure encryption algorithms, scientists have warned. A new study claims that quantum computers could render widely used cryptographic security systems obsolete with far fewer qubits, or qubits, than scientists widely predicted, putting sensitive data such as banking information and […]
Artemis II timeline: 12 key steps that will take NASA astronauts to the moon and back
After years of frustrating delays, NASA’s Artemis II mission is about to launch astronauts to the lunar environment for the first time since the Apollo 17 mission in 1972, taking the next big step toward the agency’s ambitious goal of building humanity’s first moon base. Artemis II’s record-breaking crew — which includes commander Reid Wiseman, […]
