Chimpanzees gesture back and forth quickly like in human conversations      (via sciencedaily.com)     Original source 

When people are having a conversation, they rapidly take turns speaking and sometimes even interrupt. Now, researchers who have collected the largest ever dataset of chimpanzee 'conversations' have found that they communicate back and forth using gestures following the same rapid-fire pattern.

Another intermediate-mass black hole discovered at the center of our galaxy      (via sciencedaily.com)     Original source 

So far, only about ten intermediate-mass black holes have been discovered in the entire universe. The newly identified black hole causes surrounding stars in a cluster to move in an unexpectedly orderly way.

The courtship of leopard seals off the coast of South America      (via sciencedaily.com)     Original source 

A pioneering study has unveiled the first paired observations of sexual behavior and vocalizations in wild leopard seals. The study on the mysterious leopard seal represents a major advance in understanding the behavior of one of the most difficult apex predators to study on Earth.

What fat cats on a diet may tell us about obesity in humans      (via sciencedaily.com)     Original source 

Pet cats may be excellent animal models for the study of obesity origins and treatment in humans, a new study of feline gut microbes suggests -- and both species would likely get healthier in the research process, scientists say.

Smart soil can water and feed itself      (via sciencedaily.com)     Original source 

A newly engineered type of soil can capture water out of thin air to keep plants hydrated and manage controlled release of fertilizer for a constant supply of nutrients.

Cuttlefish can form false memories, too      (via sciencedaily.com)     Original source 

During an event, details like what you saw, smelled, and felt aren't stored as a single memory. Rather, they are encoded and stored in your brain separately. To retrieve that memory, those pieces must get put back together. When that doesn't happen in the right way or details are distorted, it can lead to the creation of false memories. Now researchers have evidence that the common cuttlefish may create false memories, too.

Sun-like stars found orbiting hidden companions      (via sciencedaily.com)     Original source 

Astronomers have uncovered what appear to be 21 neutron stars in orbit around stars like our Sun. The discovery is surprising because it is not clear how a star that exploded winds up next to a star like our Sun.

Food aroma study may help explain why meals taste bad in space      (via sciencedaily.com)     Original source 

A new study on common food aromas may help explain why astronauts report that meals taste bland in space and struggle to eat their normal nutritional intake. This research has broader implications for improving the diets of isolated people, including nursing home residents, by personalizing aromas to enhance the flavor of their food.

JWST unveils stunning ejecta and CO structures in Cassiopeia A's young supernova      (via sciencedaily.com)     Original source 

Researchers announced the latest findings from the James Webb Space Telescope (JWST) of the supernova remnant, Cassiopeia A (Cas A). These observations of the youngest known core collapse supernova in the Milky Way provide insights into the conditions that lead to the formation and destruction of molecules and dust within supernova ejecta. The study's findings change our understanding of dust formation in the early universe in the galaxies detected by JWST 300 million years after the Big Bang.

Cosmic wrestling match      (via sciencedaily.com)     Original source 

Our universe is around 13.8 billion years old. Over the vastness of this time, the tiniest of initial asymmetries have grown into the large-scale structures we can see through our telescopes in the night sky: galaxies like our own Milky Way, clusters of galaxies, and even larger aggregations of matter or filaments of gas and dust. How quickly this growth takes place depends, at least in today's universe, on a sort of wrestling match between natural forces: Can dark matter, which holds everything together through its gravity and attracts additional matter, hold its own against dark energy, which pushes the universe ever further apart?

Vivid portrait of interacting galaxies marks Webb's second anniversary      (via sciencedaily.com)     Original source 

Two for two! A duo of interacting galaxies commemorates the second science anniversary of NASA's James Webb Space Telescope, which takes constant observations, including images and highly detailed data known as spectra. Its operations have led to a 'parade' of discoveries by astronomers around the world.

How the 'heart and lungs' of a galaxy extend its life      (via sciencedaily.com)     Original source 

Galaxies avoid an early death because they have a 'heart and lungs' which effectively regulate their 'breathing' and prevent them growing out of control, a new study suggests. If they didn't, the universe would have aged much faster than it has and all we would see today is huge 'zombie' galaxies teeming with dead and dying stars. That's according to a new study that investigates one of the great mysteries of the Universe -- why galaxies are not as large as astronomers would expect.

First ever 3D reconstruction of 52,000-year-old woolly mammoth chromosomes thanks to serendipitously freeze-dried skin      (via sciencedaily.com)     Original source 

An international research team has assembled the genome and 3D chromosomal structures of a 52,000-year-old woolly mammoth -- the first time such a feat has been achieved for any ancient DNA sample. The fossilized chromosomes, which are around a million times longer than most ancient DNA fragments, provide insight into how the mammoth's genome was organized within its living cells and which genes were active within the skin tissue from which the DNA was extracted. This unprecedented level of structural detail was retained because the mammoth underwent freeze-drying shortly after it died, which meant that its DNA was preserved in a glass-like state.

A new species of extinct crocodile relative rewrites life on the Triassic coastline      (via sciencedaily.com)     Original source 

The surprising discovery of a new species of extinct crocodile relative from the Triassic Favret Formation of Nevada, USA, rewrites the story of life along the coasts during the first act of the Age of Dinosaurs. The new species Benggwigwishingasuchus eremicarminis reveals that while giant ichthyosaurs ruled the oceans, the ancient crocodile kin known as pseudosuchian archosaurs ruled the shores across the Middle Triassic globe between 247.2 and 237 million years ago.

Lion with nine lives breaks record with longest swim in predator-infested waters      (via sciencedaily.com)     Original source 

A record-breaking swim by two lion brothers across a predator-infested African river has been documented in a new study. The researchers say the 1km swim is another example of iconic wildlife species having to make tough decisions to find homes and mates in a human-dominated world.
