A new technique creates greater fidelity in bioprinting functional human tissues
Researchers have made significant advances in solving some of the most vexing challenges in bioprinting 3D-engineered tissues while meeting the key requirements of high cell density, high cell viability and fine fabrication resolution.
Custom, 3D-printed heart replicas look and pump just like the real thing
Engineers developed a procedure to 3D print a soft and flexible replica of a patient’s heart. These models could help doctors tailor treatments, such as aortic valves, to an individual patient.
Physicists give the first law of thermodynamics a makeover
Physicists at West Virginia University have made a breakthrough on an age-old limitation of the first law of thermodynamics.
Early Cretaceous shift in the global carbon cycle affected both land and sea
Geologists doing fieldwork in southeastern Utah’s Cedar Mountain Formation found carbon isotope evidence that the site, though on land, experienced the same early Cretaceous carbon-cycle change recorded in marine sedimentary rocks in Europe. This ancie…
‘Forbidden’ planet orbiting small star challenges gas giant formation theories
Astronomers have discovered an unusual planetary system in which a large gas giant planet orbits a small red dwarf star called TOI-5205. Their findings challenge long-held ideas about planet formation.
Hands-free tech adds realistic sense of touch in extended reality
Researchers have demonstrated a new hands-free approach to convey realistic haptic feedback in virtual reality (VR). Their ‘multisensory pseudo-haptics’ uses a combination of headset visuals and tactile feedback from a wrist bracelet to convey sensatio…
Physically demanding work tied to higher male fertility, study suggests
A new study suggests that men who regularly lift heavy objects at work have higher sperm counts.
As sea ice declines in the Arctic, bowhead whales are adjusting their migration patterns
As sea ice declines in the Arctic, bowhead whales are staying north of the Bering Strait more frequently, a shift that could affect the long-term health of the bowhead population and impact the Indigenous communities that rely on the whales, a new stud…
Ramping up domestic graphite production could aid the green energy transition
Given the growing importance of graphite in energy storage technologies, a team of esearchers has conducted a study exploring ways to reduce reliance on imports of the in high-demand mineral, which powers everything from electric vehicles (EVs) to cell…
Artificial intelligence conjures proteins that speed up chemical reactions
Scientists have used machine learning to create brand-new enzymes, which are proteins that accelerate chemical reactions. This is an important step in the field of protein design as new enzymes could have many uses across medicine and industrial manufa…
AI experts suggest 39 percent of time currently spent on chores could be automated within the next decade
On average, 39 percent of time currently spent on unpaid domestic work could be automated within the next decade, suggest AI experts.
Archaeologists uncover early evidence of brain surgery in Ancient Near East
A recent excavation in Megiddo, Israel, unearthed the earliest example of a particular type of cranial surgery in the Ancient Near East — and potentially one of the oldest examples of leprosy in the world.
High infant mortality rates and global human population rise
New research showing high infant mortality rates are contributing to an incessant rise of the global human population supports arguments for greater access to contraception and family planning in low- and middle-income nations.
