By the ‘strength’ of a material, we usually mean the degree to which it can withstand deformation by an external force. So, the strongest materials are generally those with high densities because the closer the constituent atoms are, the greater the resistance they have to further compression.
A geology professor from the University of South Florida discovered a 5600-year-old stone bridge in an ancient cave that proves humans were present on the island of Mallorca much earlier than previously believed.
This discovery will change everything we thought and knew about early human history in the Western Mediterranean.
The question confounded archaeologists for decades. Logically, being so close to the mainland, the first signs of human settlement offshore should be on Mallorca. Instead, smaller islands farther out to sea suggest that humans skipped this island.
This gene therapy treats LCA1, causing early childhood vision loss, affecting under 100,000 people:
“One patient reported for the first time being able to navigate at midnight outdoors only with the light of a bonfire,” said Cideciyan, who is also co-director of the Center for Hereditary Retinal Degenerations.
The clinical trials were co-led by researchers from the Perelman School of Medicine at the University of Pennsylvania.
Quantum Teleportation Over 44 Kilometers Achieved, Paving the Way for a Quantum Internet Revolution
A team from Fermilab and the University of Calgary has achieved long-distance quantum teleportation over 44 kilometers, setting a new record. This breakthrough, detailed in Physical Review, advances the goal of creating a quantum internet—where qubits can be shared instantly through entanglement. This new capability could revolutionize data storage, precision sensing, and computing. The research demonstrates the potential for scaling up quantum systems and contributes to developing a blueprint for a national quantum internet. The previous record was only six kilometers, highlighting the significant progress made.
The material displays characteristics across a wide temperature range aiding versatile applications:
There is always a trade-off when balancing strength and flexibility. One is achieved at the cost of the other. While a flexible, shape-shifting aircraft can deliver benefits for higher energy efficiency and faster transportation, these cannot be achieved by risking the safety of the passengers using a material that lacks proper strength.
Researchers at the National Institute of Materials Science (NIMS) in Japan may have just found a way to achieve both strength and flexibility in a material without making any sacrifices on either.

For the study, the researchers analysed blood samples and medical information from 27,939 healthcare providers living in the US, who participated in the Women’s Health Study. The women were on average aged 55 at the study’s start (1992−1995) and followed for 30 years.
