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.
