Published Better tools needed to determine ancient life on Mars


Current state-of-the-art instrumentation being sent to Mars to collect and analyze evidence of life might not be sensitive enough to make accurate assessments, according to new research.
Published Researchers discover mysterious source of 'heartbeat-like' radio bursts in a solar fare


A solar radio burst with a signal pattern, akin to that of a heartbeat, has been pinpointed in the Sun's atmosphere, according to a new study. An international team of researchers has reported uncovering the source location of a radio signal coming from within a C-class solar flare more than 5,000 kilometers above the Sun's surface.
Published Improving the performance of satellites in low Earth orbit


On-chip distributed radiation sensors and current-sharing techniques can be used to reduce the impact of radiation on the radio and power consumption of small satellites, respectively. New findings can be used to make small satellites more robust, which can increase the connectivity of networks across the globe.
Published Physicists create new model of ringing black holes



A new analysis has modeled black hole collisions in more detail and revealed so-called nonlinear effects within gravitational waves. Nonlinear effects happen 'when waves on the beach crest and crash.'
Published Newly discovered form of salty ice could exist on surface of extraterrestrial moons



An international team has found two new crystal structures for salty ice, or solid hydrate made from water and sodium chloride. The newly discovered material's properties match those of the substance seen on the surface of icy moons, like Europa and Ganymede, and may offer clues to their icy oceans.
Published Space travel influences the way the brain works



Scientists have found how the human brain changes and adapts to weightlessness, after being in space for 6 months. Some of the changes turned out to be lasting -- even after 8 months back on Earth.
Published Astrophysics: Scientists observe high-speed star formation



New observations have brought to light that stars can form through the dynamic interaction of gas within interstellar gas clouds. This process unfolds faster than previously assumed, research within the FEEDBACK programme on board the flying observatory SOFIA revealed.
Published Tadpole playing around black hole



A peculiar cloud of gas, nicknamed the Tadpole due to its shape, appears to be revolving around a space devoid of any bright objects. This suggests that the Tadpole is orbiting a dark object, most likely a black hole 100,000 times more massive than the Sun. Future observations will help determine what is responsible for the shape and motion of the Tadpole.
Published Does ice in the Universe contain the molecules making up the building blocks of life in planetary systems?



If you want to build a habitable planet, ice is a key ingredient. The ice can be found in enormous clouds in the Universe and it is the main carrier of the necessary elements such as carbon, hydrogen, oxygen, nitrogen and sulphur. These elements are part of the atmosphere around planets and part of molecules like sugar, alcohols and simple amino acids as well. The new James Webb Space Telescope (JWST) has contributed to the discovery of different ices in a molecular cloud, 'Chameleon 1' -- one of the coldest and darkest regions to have ever been explored. Astronomers assume that these types of molecules were also present in the cold cloud of gas and dust forming our own solar system.
Published Oldest spinosaur brains revealed


Researchers have reconstructed the brains and inner ears of two British spinosaurs, helping uncover how these large predatory dinosaurs interacted with their environment.
Published Researchers uncover 92 fossil nests belonging to some of India's largest dinosaurs


The discovery of more than 250 fossilized eggs reveals intimate details about the lives of titanosaurs in the Indian subcontinent, according to a new study.
Published Fossils reveal dinosaurs of prehistoric Patagonia



A study is providing a glimpse into dinosaur and bird diversity in Patagonia during the Late Cretaceous, just before the non-avian dinosaurs went extinct. The fossils represent the first record of theropods -- a dinosaur group that includes both modern birds and their closest non-avian dinosaur relatives -- from the Chilean portion of Patagonia. The researchers' finds include giant megaraptors with large sickle-like claws and birds similar to todays ducks and geese.
Published The other paleo diet: Rare discovery of dinosaur remains preserved with its last meal


Microraptor was an opportunistic predator, feeding on fish, birds, lizards -- and now small mammals. The discovery of a rare fossil reveals the creature was a generalist carnivore in the ancient ecosystem of dinosaurs.
Published What the inner ear of Europasaurus reveals about its life


Europasaurus is a long-necked, herbivorous dinosaur that lived in the Late Jurassic, about 154 million years ago, on a small island in modern-day Germany. Recently, scientists examined fossil braincase material of Europasaurus with the aid of micro-computed tomography (micro-CT). The digital reconstruction of the inner ear of Europasaurus gave the researchers new insights not only into its hearing ability, but also into its reproductive and social behavior.
Published Scientists discover what was on the menu of the first dinosaurs


The earliest dinosaurs included carnivorous, omnivorous and herbivorous species, according to a team of palaeobiologists.
Published Climate change played key role in dinosaur success story


Climate change, rather than competition, played a key role in the ascendancy of dinosaurs through the Late Triassic and Early Jurassic periods.
Published Dinosaur teeth reveal what they didn't eat


Scratches on dinosaur teeth could reveal what they really ate. Dental microwear texture analysis (DMTA) has now been used to infer the feeding habits of large theropods, including Allosaurus and T. rex. By taking 3D images of individual teeth and analyzing the pattern of marks scratched into them, researchers could reason which dinosaurs may have frequently crunched on hard bone and which may have regularly eaten softer foods and prey. This technique opens up a new avenue of research for paleontology, helping us to better understand not only dinosaurs themselves but also the environment and communities in which they lived.
Published Dinosaurs were on the up before asteroid downfall


Dinosaurs dominated the world right up until a deadly asteroid hit the earth, leading to their mass extinction, some 66 million years ago, a landmark study reveals. Fresh insights into dinosaurs' ecosystems -- the habitats and food types that supported their lives -- suggests that their environments were robust and thriving, right up until that fateful day, at the end of the Cretaceous period.
Published Ankylosaurs battled each other as much as they fought off T. rex


Scientists have found new evidence for how armored dinosaurs used their iconic tail clubs. The exceptional fossil of the ankylosaur Zuul crurivastator has spikes along its flanks that were broken and re-healed while the dinosaur was alive -- injuries that the scientists think were caused from a strike by another Zuul's massive tail club. This suggests ankylosaurs had complex behavior, possibly battling for social and territorial dominance or even engaging in a 'rutting' season for mates.
Published Fossil overturns more than a century of knowledge about the origin of modern birds


Fossilized fragments of a skeleton, hidden within a rock the size of a grapefruit, have helped upend one of the longest-standing assumptions about the origins of modern birds.
