Landing on a moving target is a challenge for all flying animals. For bumblebees, a flower swaying in the wind creates an erratic landing pad. Reaching it means matching its sideways motion while continuing to face it. When the bee turns in flight, its view of the flower changes, which complicates the feat.
Researchers have warned all summer that this year's El Niño could be record-breaking and fuel extreme weather across the globe. Earlier this month, the U.K. Secretary of State for Environment, Food and Rural Affairs urged people in Britain to stock up on food, bottled water and other basic supplies to prepare for potential severe storms this winter."We're about to experience probably the largest El Niño that has ever been seen," Dame Angela Eagle told The Guardian on Sept. 3. "If you’ve got a store of a bit of food that can keep you going for a while before the emergency services can get to you, you’re going to be a lot better off than if you haven't."But could extreme weather really limit a...
Evolution is driven by changes in DNA that sometimes promote adaptation, altering traits like disease resistance or reproduction. Often, these changes are minuscule, modifying a single letter in the DNA code—somewhat like altering a single letter on one page of a long book.
Newly discovered iron minerals could be the missing link in how water is stored in the deepest parts of Earth's mantle and transported to the upper layers, recent research reveals. The findings are crucial for understanding the mantle's motion, volcanic activity and the workings of other rocky planets, the study authors say.The researchers discovered the iron minerals, called iron oxyhydroxides, by squishing mineral samples between two tiny diamond anvils while zapping them with a laser.The two iron minerals are stable at the conditions found at the boundary between Earth's core and its mantle (the planet's middle layer), which is under "more than a million times the pressure we feel at the ...
Enceladus may naturally separate and concentrate chemicals from its hidden ocean as droplets slowly freeze and shatter on their way into space. The process could explain Cassini’s puzzling ice-grain chemistry while giving future spacecraft a powerful advantage in searching for organic compounds and clues to life.
Food in Senegal is mostly grown on small-scale, rain-dependent farms, leaving much of the population vulnerable to climate shocks, according to the World Food Programme. However, satellite crop-mapping technologies designed to monitor the impact of climate on farming are largely beyond the reach of the West African country.
Scientists may have solved why the length of Earth’s 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 Earth’s 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 Galápagos 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 islands’ 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 forest—almost 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.
The research group at the Istituto Italiano di Tecnologia in Pontedera (Pisa), led by Gianni Ciofani, has developed new organic nanoparticles that combine multiple therapeutic functions in a single material for the first time.
Most of the polarization currently roiling Congress comes from political parties rather than individual politicians, a study co-authored by University of Miami Business School associate professor Chad Kendall finds.
