Mosquitoes Target Humans Using CO2 and Dark Cues, Not by Following Each Other

Georgia Tech and MIT researchers tracked hundreds of female Aedes aegypti in 3D to show each mosquito independently uses visual cues and CO2 to fly toward humans; the strongest attraction occurs when both cues are present, causing swarming and feeding around the head and shoulders. The study, published in Science Advances, could inform smarter traps and control strategies, including intermittent suction and lighting cues rather than constant signals.

Rising Atmospheric CO2 Could Weaken Skeletons, Study Finds

A study linking rising CO2 to higher blood bicarbonate and lower calcium and phosphorus suggests bones release minerals to absorb more CO2. If atmospheric CO2 keeps increasing, skeletal weakening could emerge within about 50 years, though researchers caution that more work is needed to understand the full physiological impact.

Rising CO2 Tied to Subtle Shifts in Human Blood Chemistry

A NHANES-based study (1999–2020) finds rising atmospheric CO2 correlates with higher blood bicarbonate and opposite trends in calcium and phosphorus; although changes are small now, models suggest ongoing CO2 increases could push some blood chemistry values toward the limits of healthy ranges in the future, with bicarbonate potentially serving as a biomarker for CO2 exposure.

Ancient Air, Fresh Clues: 1.4-Billion-Year-Old Bubbles Rewrite Early Earth's Climate

Scientists extracted tiny air inclusions from 1.4‑billion‑year‑old salt crystals to directly measure Earth’s ancient atmosphere. The CO₂ levels were far lower than prior estimates, challenging the idea of a CO₂‑rich early atmosphere and suggesting a cooler, methane‑influenced climate that persisted under a faint Sun, with implications for the rise of life and hints for exoplanet habitability.

Science-Backed Tips to Enhance Your Champagne's Flavor

Research shows that champagne's taste can be affected by storage time, altitude, and environment, with older bottles losing carbonation and altitude affecting flavor perception; drinking champagne soon after purchase is recommended for optimal taste.

Geologists Uncover Substance Responsible for Diamonds' Surface Rise

A study published in Geology reveals that at least 8.2% carbon dioxide is essential for kimberlite magma to rise from the Earth's mantle and carry diamonds to the surface, improving understanding of diamond formation and exploration strategies.

Southern Ocean's 'Burp' Threatens to Accelerate Global Warming

Climate scientists warn that the Southern Ocean may release a 'burp' of stored heat after humans reduce greenhouse gas emissions, potentially reigniting global warming for over a century, especially impacting the Southern Hemisphere and vulnerable countries in the global south.

Amazon Trees Grow Larger and More Resilient Amid Rising CO₂ Levels

A recent study shows that the largest trees in the Amazon are growing taller and multiplying, likely due to increased atmospheric CO2, indicating resilience amid climate change. However, deforestation, fires, and droughts remain significant threats, and the forest's ability to offset global emissions is limited. Protecting intact forests is crucial to maintaining their role as a carbon sink and preventing ecological collapse.

The Rarity and Distribution of Alien Civilizations in the Galaxy

Research suggests that plate tectonics and balanced atmospheric CO2 are crucial for long-term habitability and the emergence of technological civilizations, making such planets extremely rare in the galaxy. The study estimates that for multiple civilizations to coexist, they would need to last tens of millions of years, and the closest ETI could be about 33,000 light-years away, highlighting the challenges in detecting extraterrestrial intelligence.

Climate Extremes Define the Age of Animals

Earth's climate has experienced a vast range of temperatures and conditions over the past half-billion years, driven primarily by atmospheric CO2 levels, with periods of extreme heat and cold that have shaped the evolution and survival of animal life. Modern climate change, caused by rapid CO2 emissions, risks pushing the planet beyond its historical bounds, threatening the biosphere.

NASA Telescope Reveals Interstellar Comet 3I/ATLAS Encased in Carbon Dioxide Fog

NASA's SPHEREx telescope has revealed that the interstellar comet 3I/ATLAS is wrapped in carbon dioxide fog and water ice, indicating it was well-processed before ejection from its parent system, likely originating from far away in the Milky Way's thick disk. This discovery provides insights into the composition of interstellar objects and demonstrates SPHEREx's advanced capabilities in sky mapping and chemical analysis.

Scientists Reveal Bizarre Nature of Interstellar Comet 3I/ATLAS

Multiple powerful telescopes including Hubble, TESS, JWST, and SPHEREx have observed interstellar comet 3I/ATLAS, revealing it to be unusually active at a greater distance from the Sun than typical comets and possessing a high proportion of carbon dioxide in its coma, suggesting unique formation conditions or composition. The comet's trajectory and activity provide valuable insights, with further observations expected after perihelion and as it leaves the Solar System.
