How researchers push and pull metal for cleaner cooling

From Science Magazine. Read the paper here: https://www.science.org/doi/10.1126/science.adg7043 Traditional cooling devices like air conditioners rely on refrigerants that can harmful to humans and the environment. Materials scientist Ichiro Takeuchi and his research group have developed a cooling device free of typical toxic refrigerants, instead relying on a physical property of certain metal alloys. These alloys…

How AI is pushing medical robotics toward autonomy

From Science Magazine. Artificial intelligence (AI) applications in medical robots are bringing a new era to medicine. Advanced medical robots can perform diagnostic and surgical procedures, aid rehabilitation, and provide prosthetics to replace limbs. The combination of extraordinary advances in robotics, medicine, materials science, and computing could bring safer, more efficient, and more widely available…

Slow motion tongues offer a snapshot of evolution

From Science Magazine. Read the article: https://www.science.org/content/article/how-tongue-shaped-life-on-earth An early interest in reptile feeding behavior led evolutionary biologist Kurt Schwenk to study the tongues of lizards. Like Charles Darwin’s finches, the various forms and functions of lizard tongues help piece together the story how the diversity of reptiles and amphibians evolved. In this video he explains…

Here’s how much water lakes around the world have lost

From Science Magazine. Some of the most notable lakes in the world, from the Great Salt Lake to Poyang Lake, have shrunk dramatically in recent decades. But because most lakes lack long-term, on-the-ground measurements, it was hard to say whether this was a widespread phenomenon. Now, researchers have published a first-of-its-kind data set to look…

Quakes and blasts help scientists understand Earth’s elusive inner core

From Science Magazine. Read the story: https://www.science.org/content/article/scientists-probing-secrets-earths-inner-core-saved-life-planet About the size of Pluto, Earth’s inner core is made of solid iron and helps power the magnetic field that protects life from harmful space radiation. For more than a century, seismic waves have helped researchers identify and characterize the core’s properties. Science reporter Paul Voosen wrote about…

Honey bees perfect their waggle dances by learning from elders

From Science Magazine. Read the paper: https://www.science.org/doi/10.1126/science.ade1702 Read the Perspective: https://www.science.org/doi/10.1126/science.adg6020 The waggle dance performed by honey bees is a complex behavior that communicates directional information. In a recent paper, researchers demonstrated that younger bees learn critical parts of this dance from older, more experienced bees. Bees that learn without the benefit of teachers have…

Gravitational Wave Background | Scientists use a living laboratories called pulsar timing arrays

From Science Magazine. Read the Perspective: https://www.science.org/doi/10.1126/science.abq1187 In order to detect the background hum of gravitational waves in the cosmos, scientists monitor the light coming from dead stars called pulsars. These pulsars produce flashes of light with incredible regularity, allowing researchers to calculate when they would expect to detect these flashes. The difference between the…

JWST’s golden eye sees the universe anew

From Science Magazine. Not many telescopes get introduced by the president, but JWST, the gold-plated wunderkind of astronomy built by NASA with the help of the European and Canadian space agencies, deserves that honor. It is the most complex science mission ever put into space and at $10 billion the most expensive. And it did…
