· Scientists used a 5,564-qubit quantum computer to simulate and observe "false vacuum decay" — a process that could determine our Universe's ultimate fate by transitioning it to a more stable state· The research team created and tracked quantum bubbles containing up to 306 qubits, revealing how smaller bubbles bounce around among larger ones in a complex quantum dance that persisted for over 1,000 qubit time units· This breakthrough demonstrates how table-top quantum experiments can help us understand fundamental cosmic processes without requiring massive facilities like the Large Hadron ColliderNearly 50 years ago, physicist Sidney Coleman proposed an intriguing idea:...

Doctors hail new era for cancer screening as major research shows effectiveness of Galleri test Doctors have told health services to prepare for a new era of cancer screening after a study found a simple blood test could spot multiple cancer types in patients before they develop clear symptoms. The Pathfinder study offered the blood test to more than 6,600 adults aged 50 and over, and detected dozens of new cases of disease. Many cancers were at an early stage and nearly three-quarters were forms not routinely screened for. It is the first time results from the Galleri test, which...

WASHINGTON (Reuters) - A new chemical compound, part-cat and part-human, may provide an end to misery-making cat allergies, U.S. researchers reported on Sunday. And they said their approach in creating the compound may work against more dangerous allergies, such as deadly peanut allergies. The compound, tested in mice bred to be allergic to cats, virtually shut down the histamine reaction that causes the uncomfortable symptoms of cat allergies such as runny eyes, sneezing and itching, Dr. Andrew Saxon of the University of California Los Angeles School of Medicine and colleagues reported. Writing in the April issue of Nature Medicine, they...

SAN FRANCISCO (AP) - Many U.S. residents carry unhealthy levels of pesticides in their bodies, with children, women and Mexican Americans disproportionately exposed to the toxic chemicals, according to a study released Tuesday. The Pesticide Action Network analyzed data collected by the U.S. Centers for Disease Control and Prevention in a study of more than 2,648 people tested for levels of 34 pesticides, the environmental group said. The PAN study - called "Chemical Trespass: Pesticides in Our Bodies and Corporate Accountability" - found that a large percentage of people who had their blood and urine tested carried pesticides above levels...
