How to simulate softness

What factors affect how human touch perceives softness, like the feel of pressing your fingertip against a marshmallow, a piece of clay or a rubber ball? By exploring this question in detail, researchers discovered clever tricks to design materials that replicate different levels of perceived softness. The findings provide fundamental insights into designing tactile materials and haptic interfaces...

Discovery paves the way for earlier detection of type 1 disease

Scientists have discovered what may be the earliest possible biological marker of type 1 diabetes, formerly known as juvenile type 1 diabetes. If their mouse study can be replicated in humans, which they are now attempting to do, the timing of therapeutic intervention may be drastically improved for patients who are on course to develop the disease.

Oxygen depletion in ancient oceans caused major mass extinction

For years, scientists struggled to connect a mechanism to this mass extinction, one of the 10 most dramatic ever recorded in Earth's history. Now, researchers have confirmed that this event, referred to by scientists as the Lau/Kozlowskii extinction, was triggered by an all-too-familiar culprit: rapid and widespread depletion of oxygen in the global oceans.

Evidence for past high-level sea rise

Scientists, studying evidence preserved in speleothems in a coastal cave, illustrate that more than three million years ago -- a time in which the Earth was two to three degrees Celsius warmer than the pre-industrial era -- sea level was as much as 16 meters higher than the present day.

Early start of 20th century Arctic sea ice decline

Arctic sea-ice has decreased rapidly during the last decades in concert with substantial global surface warming. Both have happened much faster than predicted by climate models, and observed Arctic warming is much stronger than the global average. Projections suggest that Arctic summer sea-ice may virtually disappear within the course of the next fifty or even thirty years.

Storage and release of mechanical waves without energy loss

A new discovery could allow light and sound waves to be stored intact for an indefinite period of time and then direct it toward a desired location on demand. Such a development would greatly facilitate the ability to manipulate waves for a variety of desired uses, including energy harvesting, quantum computing, structural-integrity monitoring, information storage, and more.

New radiomics model uses immunohistochemistry to predict thyroid nodules

Researchers have validated a first-of-its-kind machine learning-based model to evaluate immunohistochemical characteristics in patients with suspected thyroid nodules, achieving 'excellent performance' for individualized noninvasive prediction of the presence of cytokeratin 19, galectin 3, and thyroperoxidase based upon CT images.

AI uncovers new details about Old Master paintings

Artificial intelligence can be used to analyse high-resolution digital X-ray images of paintings, providing more insight for conservators and those restoring classic works of art. A new algorithm was developed and used on the world famous Ghent Altarpiece, as part of an investigative project led by UCL. The finding is expected to improve our understanding of art masterpieces and provide new...
