Tech Xplore / Ultra-thin semiconductors overcome performance limits with localized thick-contact design
As semiconductor chips become increasingly thinner, the components inside chips are locked in a fierce race to achieve the ultimate ultra-thin state. However, this has presented a structural limitation: the thinner the device, ...
Medical Xpress / Brain cells fine-tuned to disappointment may inspire new therapies for depression and addiction
University of Oregon neuroscientists have identified a group of brain cells that essentially act as a "disappointment meter," announcing when reality is falling short of expectations.
Phys.org / Embryonic tissues can behave like fluids or solids to reshape cell fate signals
Embryonic development is one of the most dynamic biological processes in nature. Cells and tissues organize and reorganize themselves following incredibly precise patterns, while remaining flexible and robust. Scientists ...
Medical Xpress / New RNA sequencing method reveals hidden layer of immune system control
Researchers at University Medical Center Utrecht have uncovered a previously underappreciated mechanism that helps immune cells to respond rapidly to infections. Using advanced long-read RNA sequencing, the team shows that ...
Phys.org / Green stones buried with Panama's ancient chiefs confirmed as Colombian emeralds
More than 1,000 years ago, Panama elites were buried together with translucent green stones long suspected to be emeralds. However, scientific analysis confirming the suspicion has never been conducted. Now, scientists have ...
Medical Xpress / The hum that only a few can perceive: Potential sources of a low-frequency sound
Some people occasionally hear a low buzzing or humming sound that doesn't have a clear source. An estimated 2–4% of the world's population hear this. Scientists have been trying to figure out for decades where this sound ...
Phys.org / Twilight hunt reveals falcon feasting on unusual prey at Greek lagoon
Falcons are lauded for their speed and agility. The Eurasian Hobby (Falco subbuteo), skilled at snagging birds and insects out of the air, is no exception. However, during twilight on one day in October, researcher Apostolos ...
Phys.org / Thirty years at El Mirón cave uncover 40,000 years of Iberian prehistory
For the past three decades, a team of archaeologists have been uncovering some of the field's most recent monumental discoveries, relying on gut instinct, persistent hard work, and cutting-edge methods and technologies.
Phys.org / Robot fish could unravel how our ancient ancestors first learned to walk
Researchers have developed a fish-like robot that shows how some species of modern fish are able to walk on land, and could help unravel how early vertebrates evolved similar abilities hundreds of millions of years ago.
Phys.org / A kohl bottle from York may hint at an ancient Egyptian in Roman-Britain
Ancient Egyptians are often depicted wearing black eyeliner, known as kohl, which was stored in small containers. While kohl containers are typically found throughout Egypt and Sudan (Nubia), their presence beyond these areas ...
Medical Xpress / New hand sensors turn post-stroke rehab into an on-screen game
New paper-thin piezoelectric patch sensors designed for at-home stroke rehabilitation may soon revolutionize post-stroke care by offering potential accessible, efficient rehabilitation and improving patient outcomes through ...
Phys.org / Clean drinking water gaps linked to hunger and unsafe food worldwide
A new global study has found that people without access to clean drinking water are significantly more likely to experience food insecurity and food safety threats, underscoring the urgent need for coordinated global action ...
