Woodpeckers’ taste: Sweet sap, savory ants

Many mammals have a sweet tooth, but birds lost their sweet receptor during evolution. Although hummingbirds and songbirds independently repurposed their savory receptor to sense sugars, how other birds taste sweet is unclear. Now, an international team lead by researchers from the Max Planck Institute for Biological Intelligence (in foundation) shows that woodpeckers also regained …

Ferritin-mediated iron detoxification promotes hypothermia survival in Caenorhabditis elegans and murine neurons – Nature Communications

Inhibition of ETS-4 improves C. elegans survival in the cold Our initial studies of C. elegans “hibernation” identified the RNase REGE-1 as a factor promoting cold survival17. Studying REGE-1 in a different physiological context, the regulation of body fat, we showed that a key target of REGE-1 encodes a conserved transcription factor, ETS-417. Thus, we …

Meteor showers, a galactic dance and the Artemis mission to the Moon | The best images in science this week

Last weekend the whole world saw the last supermoon of 2022. The Sturgeon supermoon lit up skies across the world and featured in some amazing images. Meanwhile, the Perseid meteor shower was somewhat overshadowed by the full Moon, but still produced some great sights. NASA continues to prepare for Artemis, which the launch of the …

Asteroid Ryugu Reveals Ancient Grains of Stardust Older Than The Solar System

Asteroid Ryugu Reveals Ancient Grains of Stardust Older Than The Solar System

Tiny fragments of rock brought back from an asteroid in near-Earth solar orbit are so old, they predate the Solar System. A new analysis of samples of asteroid Ryugu has revealed the presence of mineral grains forged in the outflows or explosions of old stars before our own Sun formed. As identified by previous research, …

After 45 years, the 5-billion-year legacy of the Voyager 2 interstellar probe is just beginning

After 45 years, the 5-billion-year legacy of the Voyager 2 interstellar probe is just beginning

On August 20 1977, 45 years ago, an extraordinary spacecraft left this planet on a journey like no other. Voyager 2 was going to show us, for the first time, what the outer solar system planets looked like close-up. It was like sending a fly to New York City and asking it to report back. …

Sharpest image ever of universe’s most massive known star

Sharpest image ever of universe’s most massive known star

image: Nestled in the center of the Tarantula Nebula in the Large Magellanic Cloud is the largest star yet discovered. With the help of the Zorro imager and the power of the 8.1-meter Gemini South telescope in Chile, astronomers have produced the sharpest image ever of this star. This new image challenges our understanding of the …

Researchers design new inks for 3D-printable wearable bioelectronics: Potential uses include printing electronic tattoos for medical tracking applications

Flexible electronics have enabled the design of sensors, actuators, microfluidics and electronics on flexible, conformal and/or stretchable sublayers for wearable, implantable or ingestible applications. However, these devices have very different mechanical and biological properties when compared to human tissue and thus cannot be integrated with the human body. A team of researchers atTexas A&M University …

An Asteroid Impact Crater Beneath The North Atlantic Ocean - And The Demise Of Dinosaurs - Astrobiology

An Asteroid Impact Crater Beneath The North Atlantic Ocean – And The Demise Of Dinosaurs – Astrobiology

Nadir Crater Heriot-Watt University Scientists have found evidence of an asteroid impact crater beneath the north Atlantic ocean. The 8.5km-wide crater is buried 300-400m below the seabed 400km off the coast of Guinea, west Africa. The team believes the crater was caused by a 400m-wide asteroid colliding with Earth around 66 million years ago – …
