One of the most recognisable and feared predators within our oceans is, of course, the shark, and this is because of its greatly powerful and continually regrowing teeth. But aside from serving as a feeding mechanism, shark teeth play a very important part in how sharks can effectively hunt and keep themselves at the top…
What happened to NASA’s ‘Moon Trees’ after they orbited the Moon on Apollo 14 (Image source: Wikipedia) What NASA accomplished in the early 1970s is a little-known but truly impressive feat. Instead of putting rockets or robots in space, they put seeds there. Seeds of different trees accompanied astronauts on the Apollo 14 mission in…
Baby dinosaur fossils found in Arctic permafrost reveal how dinosaurs survived polar winters (Image source: AI- Generated) In a startling flip-flop on our perspectives on ancient civilisations, scientists have discovered baby dinosaur fossils buried in Arctic permafrost, thereby validating that dinosaurs did nest in the polar regions. These fossils of dinosaurs that are merely 2…
Pannotia occupies an awkward position in Earth science. It is described in textbooks and review papers, yet its outline remains faint. The proposed supercontinent is said to have existed around 600 million years ago, before the better-known Pangea. For years, it offered a neat bridge between the breakup of Rodinia and the later assembly of…
Source: The New York Times NASA has shown off fresh details of its long-awaited Artemis II mission, marking a major step in the return of humans to deep space. For the first time in more than five decades, astronauts are preparing to fly around the Moon, testing systems designed eventually to take humans back to…
Cockroaches are usually treated as simple creatures that react without pause, driven by instinct rather than experience. New laboratory work from Scotland suggests the picture is less fixed. Researchers found that male cockroaches altered their behaviour after exposure to stress, becoming more cautious when faced with uncertain signals. The study focused on how insects respond…
NASA has completed a series of scientific balloon flights over Antarctica during a campaign that began in early December. Four balloons were launched from a site near McMurdo Station on the Ross Ice Shelf and remained in flight for several weeks. The flights were part of NASA’s ongoing Scientific Balloon Program, which supports research using…
WASHINGTON: The scientists have discovered that the adolescent brain does more than prune old connections. During the teen years, it actively builds dense new clusters of synapses in specific parts of neurons. These clusters emerge only in adolescence and may help shape higher-level thinking. When the process is disrupted, it could play a role in…
Scientists who work on long-term climate patterns usually stay close to Earth. The data is here, the records are clearer, and the risks are immediate. A new study shifts that focus slightly outward. Research published in the Publications of the Astronomical Society of the Pacific suggests that Mars plays a role in shaping Earth’s climate…
Research into how decisions are made often starts with people. Occasionally, it drifts elsewhere. A study from Yale University points to something familiar showing up in monkeys. The focus is on loss aversion, a pattern where avoiding loss matters more than gaining something new. In controlled tests, capuchin monkeys were observed trading tokens for food…
