Scientists may have solved why the length of Earthās day changes by a few milliseconds over decades. Subtle shifts in the inner core appear to tug on the mantle, revealing a surprisingly dynamic world thousands of kilometers beneath our feet.
NASA and SpaceX could launch four astronauts to the International Space Station on October 1, with the Dragon spacecraft reaching orbiting outpost less than nine hours after liftoff. Crew-13 will join Expedition 75 after teams complete a final round of intensive launch-readiness checks.
CosmoCube will use the far side of the Moon as a shield from Earthās radio noise to search for a faint signal from the universe before the first stars existed. The suitcase-sized satellite could reveal how the cosmic dark ages ended and how dark matter helped build the first galaxies.
Yellow-morph green sea turtles in the GalĆ”pagos surprised scientists by staying remarkably close to home instead of making the long journeys typically associated with sea turtles. Satellite tracking showed that none left the marine reserve during the study, revealing just how important the islandsā coastal habitats may be to their survival.
Japan's population peaked around 2008 and has been steadily declining since. But construction hasn't stopped.
Scientists have discovered a stem cell that appears to serve as a master source for tendon and ligament cells throughout the body. In lumbar spinal stenosis, these cells become unusually active and may drive the ligament overgrowth that squeezes spinal nerves and causes pain, numbness, and difficulty walking. Researchers found that reducing calcium signaling stopped this abnormal growth in mice.
A study based on publication data traces how researchers moved within Ukraine and across borders between 2009 and 2022, with conflict-affected regions losing scholars while others became increasingly important destinations. These shifts were already underway after Russia illegally annexed Crimea and fighting began in the Donbas in 2014, underscoring that scholarly mobility during conflict cannot simply be understood as a matter of free choice.
Scientists have discovered a new tick-borne virus in China that causes flu-like illness and may account for previously unexplained cases of fever, fatigue, digestive problems, and low platelet counts. Most patients with ALTNV alone recovered, but coinfections with another dangerous tick-borne virus were linked to more serious complications.
Many cancers associated with infection are preventable
Not happy with the election result? Don't worry. Election Day is not the only opportunity to influence politics.
Former Brazilian President Jair Bolsonaro contributed to deforestation through statements opposing forest conservation, according to an international study led by the University of Bonn. The study found that destruction of the Amazon rainforest accelerated when Bolsonaro and his ministers posted messages opposing forest conservation on Twitter. Brazil's environmental authorities were greatly weakened during Bolsonaro's presidency, but the analysis suggests that even a perceived low risk of punishment was a driver of deforestation. The researchers estimate that the statements contributed to the destruction of up to 1,700 square kilometers (660 square miles) of forestāalmost double the area of...
In acute, life-threatening infections, rapidly characterizing the microorganisms in a patient sample can help guide diagnosis and treatment. Computational methods known as taxonomic profilers can analyze metagenome sequencing data generated from the microorganisms' genomic information and compare it with reference genomes of individual microorganisms. However, taxonomic profilers are still under development and are not yet in common use. Current methods can produce false-positive results or inaccurate abundance estimates.
