Earliest example of placental mammal fossil discovered

Palaeontologists studied growth lines and elements preserved in fossil teeth to reconstruct the day-to-day life of Pantolambda bathmodon, one of our early cousinsPalaeontologists have identified the earliest example of a placental mammal in the fossil record to date, which could provide new insights into how our furry ancestors came to dominate Earth following the extinction of the dinosaurs.They...

Unraveling the mysteries of the night sky with AI

Technische Universität Ilmenau (Germany) is using artificial intelligence to improve the detection and classification of unidentified phenomena in the night sky. The research team of the group for data-intensive systems and visualization collaborated with the American Meteor Society, which initiated the AllSky7, an international network of scientists and amateur astronomers that permanently...

Juicy research unearths new genome within the tomato family

Hidden beneath the delicate, red skin and juicy flesh of a tomato is a wealth of nutrients and genetic makeup. With recent research on the first genome of a species in the tomatillo tribe (part of the tomato family), we now have a better idea of how this vital plant family came to be.

How superwinds help drive galactic development

Galactic superwinds—large outflows of gas created by a combination of supernova explosions and stellar winds—are closely connected to a galaxy's earliest stages of development and evolution, including aspects like its size, shape, and even how many stars will eventually call it home.

Deep Concern About Food Security in Eastern Africa

According to a July 29, 2022 report from the International Food Security and Nutrition Working Group, the worst drought conditions in 70 years across the Horn of Africa have more than 16 million people coping with a shortage of drinking water. Yields of key crops are down for the third year in a row, milk production is in decline, and more than 9 million livestock animals have been lost...

MAVEN and EMM make first observations of patchy proton aurora at Mars

NASA's MAVEN and the United Arab Emirates' EMM missions have released joint observations of dynamic proton aurora events at Mars. By combining the observations, scientists determined that what they were seeing was essentially a map of where the solar wind was raining down onto the planet, opening new avenues for understanding the Martian atmosphere.

Signs of saturation emerge from particle collisions at RHIC

Nuclear physicists studying particle collisions at the Relativistic Heavy Ion Collider (RHIC) have new evidence that particles called gluons reach a steady 'saturated' state inside the speeding ions. The evidence is suppression of back-to-back pairs of particles emerging from collisions between protons and heavier ions (the nuclei of atoms), as tracked by RHIC's STAR detector. The STAR...

How the brain processes sensory information from internal organs

Most of us think little of why we feel pleasantly full after eating a big holiday meal, why we start to cough after accidentally inhaling campfire smoke, or why we are hit with sudden nausea after ingesting something toxic. However, such sensations are crucial for survival: they tell us what our bodies need at any given moment so that we can quickly adjust our behavior.

Particles pick pair partners differently in small nuclei

The protons and neutrons that build the nucleus of the atom frequently pair up. Now, a new high-precision experiment has found that these particles may pick different partners depending on how packed the nucleus is. The data also reveal new details about short-distance interactions between protons and neutrons in nuclei and may impact results from experiments seeking to tease out further details...
