The black robin, once reduced to a single breeding pair and near extinction, has been named New Zealand’s Bird of the Year after a record 105,000 votes. A pioneering conservation program using foster parenting helped its numbers rebound to about 350 adults, all on pest-free Chatham Island reserves, though the species remains threatened and its habitat is nearing capacity, requiring additional pest-free land.
Researchers have created a yeast- and gelatin-based binder to turn Martian-regolith sand into a light, porous concrete, achieving about 12 MPa compressive strength—roughly comparable to low-grade Earth concrete—which could enable small, multi-story habitats on Mars and uses far less energy than regolith-melting methods. However, such a material would need additional layers for airtightness, radiation shielding, and long-term durability, and there are questions about whether engineered yeast could survive Mars conditions and about planetary-protection concerns. The work is promising but still far from ready for actual construction.
A Frontiers in Space Technology study argues that even with high water recycling, a one-million-person Moon colony would exhaust its water in about a century, making large-scale, long-term habitation unlikely. Solar energy isn’t the bottleneck, but water is, given ice in permanently shadowed craters and potentially beneath the surface; current estimates suggest these sources may not suffice for a large settlement without new sources. Finding more ice, mining additional deposits, or importing water could change the outlook, but absent such breakthroughs the Moon may remain limited to small, water-rich outposts and an elite few.
Pokopia’s free 2.0 update adds the Dive ability for underwater exploration and building, fixes and streamlines habitat mechanics so Pokémon are less finicky about furniture, and improves item management and other QoL tweaks; the paid Bubbly Basin DLC also releases with new content.
New research suggests life on Earth could persist for roughly 1.8 billion more years as the Sun brightens and atmospheric CO2 falls. The study, based on 29 climate models, finds that plant life could endure longer if CAM photosynthesis remains prevalent, potentially up to about 1.84–1.87 billion years under certain weathering scenarios, while other plant types could end sooner (around 1.35–1.84 billion years). The timeline is tied to solar luminosity and the carbonate-silicate cycle, with life likely ending well before the Sun becomes a red giant due to ocean loss and extreme heat. The authors caution that these results assume current photosynthesis and call for more 3-D modeling to better constrain the timescales.
New research argues big brains aren’t solely a product of social living. An analysis of 79 cephalopod species shows habitat and ecological complexity better predict brain size than sociality, with bottom-dwelling, shallow-water species having larger brains even when solitary. The findings support the cultural brain hypothesis, which posits brains evolve to store and process information learned either socially or asocially, implying multiple evolutionary routes to intelligence beyond social structures. While correlation cannot prove causation, the study suggests ecology as a primary driver of cephalopod brain size and invites reevaluation of brain-evolution theories.
NASA unveiled a multi-mission Artemis roadmap to lay the groundwork for a sustained lunar base, featuring uncrewed landers, rovers and drones from Blue Origin, Astrobotic, Intuitive Machines, Astrolab and Lunar Outpost, with MoonFall drones (built by Firefly Aerospace) targeting a 2028 launch. The plan aims to establish semi-habitable infrastructure by 2032 and full surface habitats by 2036, while astronauts are expected to land on the Moon in 2028 (potentially twice that year). Whether the timeline holds depends on commercial partners delivering on schedule.
NASA plans four solid-fuel burns inside small lunar habitats to test material flammability under partial lunar gravity, evaluating whether Earth-based standards like NASA-STD-6001B apply; measurements will use cameras, radiometers, and an oxygen sensor, with a late-2026 launch goal to inform fire safety for future Moon missions.
Paleontologists in Niger announce a new Spinosaurus species, Spinosaurus mirabilis, featuring a 20-inch sword-like horn and a unique jaw arrangement, discovered inland far from the coast. The fossil suggests this fish-eating predator lived in forested river systems and grew to roughly the size of a Tyrannosaurus rex, with a sail-like back, challenging the view that Spinosaurus hunted exclusively in marine environments.
A rediscovered coastal marten (Humboldt marten) in northern California is estimated to number about 500 individuals, occupying roughly 5% of its historic range. Researchers used 135 remote cameras and 285 hair snares over 400 square kilometers to gather data, finding 28 males and 18 females and a density of about one marten per three square kilometers. The species favors complex, high-canopy forests with large trees, snags, and hollow logs. Habitat loss, climate change, and logging threaten its survival, underscoring the need for forest protection and continued monitoring.
Oregon State University researchers conducted a three-month study in 2022 in a 150-square-mile coastal area near Klamath to map the coastal marten’s population and habitat using hair-based genetic analysis, identifying 46 martens (28 males, 18 females). Martens favored high-elevation, snow-rich ridges and lower-elevation riparian/coastal forests with complex structure—forests with more than 50% canopy, many large trees, snags, and coarse woody debris. The coastal marten, once ranging from northern Oregon to northern California, declined due to fur trapping; current distribution and demography remain incompletely understood, underscoring the need for further conservation-focused research.
Turtles are aquatic reptiles with flattened shells and webbed or flipper-like feet, while tortoises are land-dwelling with domed shells and stumpy legs. Most turtles are omnivorous and live in water, whereas tortoises are herbivorous and adapted for terrestrial life, with some exceptions like the pancake tortoise.
Historically, sloths ranged from small tree-dwellers to massive ground-dwellers up to 20 feet tall, but most of the giant species went extinct around 15,000 years ago, primarily due to human hunting, with habitat changes also influencing their evolution. Today, only smaller, tree-dwelling sloths remain.
An expert was consulted to determine if Germany could accommodate 20,000 elephants, highlighting the importance of considering wildlife conservation and habitat preservation.
NASA is seeking volunteers for its yearlong simulated Mars mission, CHAPEA 2, starting in spring 2025, where four crew members will live in a 3D-printed habitat in Houston to simulate life on Mars. Applicants must be US citizens aged 30-55 with a master’s degree in a STEM field, English proficiency, and professional experience, and the mission involves habitat maintenance, crop growing, and simulated spacewalks. The first mission is currently underway, and applications are open until April 2.
