Archaeologists may have just found the world’s oldest shipwreck

A mysterious shipwreck off Turkey’s coast may be the oldest ever discovered, dating back approximately 4,500 years to the age of the Egyptian pyramids. Although the wooden vessel has disappeared, its surviving pottery cargo reveals clues about an ancient trading network that may have connected distant Mediterranean civilizations. Researchers believe the ship may have crashed against rocks during a storm while transporting valuable goods such as oil, wine, or tree resin.

AI detects “invisible” signs of pancreatic cancer years before diagnosis

A powerful new AI system could help doctors detect pancreatic cancer years before it becomes visible on conventional scans. The technology, called REDMOD, identified hidden warning signs an average of 475 days before diagnosis and was nearly twice as sensitive as experienced radiologists. By spotting cancer-related changes at their earliest stages, it could dramatically improve the chances of successful treatment for one of the deadliest forms of cancer.

Scientists discover Arctic sea ice loss could be far worse than predicted

Arctic winter sea ice could disappear much faster than scientists previously expected, according to new research using climate clues from 6,000 years ago. By comparing ancient ocean sediments with modern climate models, researchers found that future winter ice coverage may be roughly one million square kilometers smaller than earlier predictions suggested.

A simple liquid can stop cavities without drilling, major study confirms

A simple liquid painted onto teeth in seconds can stop cavities without drilling, injections, or anesthesia, according to a major clinical trial involving young children. The inexpensive treatment could spare thousands of children painful dental procedures and surgery while paving the way for broader FDA-approved use.

Scientists overcome a hidden obstacle to more powerful quantum computers

Scientists have discovered a way to operate multiple silicon qubits simultaneously with remarkable accuracy, overcoming a major challenge in scaling up quantum computers. Their new technique maintained accuracy of approximately 99.9% even when all five qubits were running at once, opening the door to larger and more powerful quantum processors.

Lumina simulation brings the early universe to life on a record-breaking scale

The James Webb Space Telescope (JWST) and Nancy Roman Space Telescope are revealing the universe's earliest chapters in detail. To help astronomers understand what they are seeing, researchers at the Center for Astrophysics | Harvard & Smithsonian have developed "Lumina," one of the largest and most detailed simulations ever created of the early universe.

Experienced teachers are quitting or reducing their hours—they’re struggling to cope

Teacher shortages are affecting school systems in countries across the world. Governments have responded with initiatives to attract graduates into teaching. While much attention has focused on increasing supply, far less attention has been paid to why experienced teachers decide to leave, despite the high costs of turnover in recruitment, training and lost continuity.

Supercurrent enables the reading of quantum information without destroying it

One of the fundamental challenges of quantum computing is obtaining information from a quantum bit, or qubit. Unlike a conventional bit, which can be read repeatedly without altering its content, direct measurement of a quantum system typically causes the state to collapse before it can be determined. In other words, reading the information modifies it.

Crows make decisions twice as fast as humans and monkeys

University of Tübingen researchers have shown that crows, when confronted with a visual choice, make a decision twice as fast as humans and monkeys. In the experiment, two carrion crows took just 235 milliseconds on average to identify the direction in which a dot pattern was moving and to indicate their choice—while maintaining a high degree of accuracy.
