New research reports that microscopic microbes in the Baltic Sea play a role in transporting carbon, contributing to the movement of carbon through marine ecosystems. The findings add to scientific understanding of how the Baltic's small-scale biology influences carbon cycling in coastal seas. Details of the study, including methods and the scale of the microbes' contribution, were not provided in the available reporting.

New reporting highlights that as oceans absorb more carbon dioxide and become more acidic, the internal chemistry of phytoplankton changes. These microscopic organisms sit at the base of the marine food web and drive much of the ocean's carbon cycling, so shifts in their chemical makeup could ripple through marine ecosystems and climate processes.

An illustrator has shared a drawing of photosynthesis accompanied by microscope slides of a leaf cross section. The slides show palisade mesophyll cells from the side, revealing that they are long and thin rather than the little circles they appear to be when viewed from above. The post has drawn a small audience of science and illustration enthusiasts.

Dr. Tyler Powell and SETI Institute researcher Dr. Sofia Sheikh appeared on Science Friday to discuss what the Moon reveals about its own history and the search for technology beyond Earth. Their conversation covered a newly discovered lunar impact crater and the hunt for microscopic technosignatures, linking planetary science with the search for extraterrestrial intelligence.

New research indicates that climate models are failing to account for tiny ocean particles that play a role in cloud formation. These microscopic particles, originating at the sea surface, help water vapour condense into droplets, meaning projections of cloud cover and warming may be less accurate than assumed. Scientists say better representation of these ocean-derived particles could improve the reliability of climate predictions.

New reporting highlights how common household chemicals, from painkillers to sunscreen ingredients, are damaging microscopic organisms that underpin aquatic ecosystems. These tiny organisms, such as algae and plankton, form the base of food webs and produce much of the oxygen in water systems. Scientists are increasingly concerned that pharmaceutical residues and UV filters in wastewater are disrupting their growth and function, with potential consequences for fish, water quality, and food chains worldwide.

Researchers studying radioactive 'hot particles' from Chernobyl found the microscopic particles, measuring between 8 and 50 micrometres, still retain their structure nearly four decades after the 1986 reactor explosion. The findings highlight how long radioactive contamination can persist in the environment around the exclusion zone, renewing discussion about the disaster's lasting legacy.

A start-up featured by The New York Times is working to develop microrobots — machines at microscopic scale — using artificial intelligence to guide their design and development. The report has drawn attention for highlighting how A.I. is being applied beyond software to the engineering of tiny physical machines.

New research suggests that microscopic algae played a decisive role in ending a massive ocean bloom that had persisted for roughly six million years. Scientists say the algae transformed ocean conditions, drawing a close to an era of extraordinary biological abundance. The finding sheds light on how small marine organisms can drive major shifts in global ecosystems, and it is drawing attention among those following ocean science and climate research.

New research into tardigrades, the microscopic animals known as water bears, suggests their remarkable resilience to extreme conditions stems from stress-protective proteins that evolved independently along similar paths in different lineages. The findings point to convergent evolution in the molecular machinery that lets these creatures survive drying, freezing and radiation, offering clues for biotechnology and stress-tolerance research.

Researchers have reported entangling a levitated glass bead with light, raising the possibility that such a suspended particle could one day serve as a quantum memory. The experiment involves trapping a microscopic bead, cooling its motion, and linking its state to photons. If the entanglement proves robust, it could open a route to storing quantum information in mechanical systems, a step of interest for future quantum technologies.

New experiments using microscopic mazes show that bacteria navigate crowded environments by relying on collisions with other cells rather than sensing their surroundings directly. Researchers found that repeated bumping helps the microbes reorient and find paths through tight spaces, offering new insight into how bacterial swarms move. The findings could inform studies of biofilms and infection spread.

An artist's eating habits — described as little more than tea and a Caramello Koala — have been put under the microscope by a dietitian writing in the Sydney Morning Herald, who offers a blunt assessment of just how poorly the diet measures up nutritionally. The piece has drawn attention for its frank take on a strikingly meagre daily menu.

Physicists are reporting that the phonon thermal hall effect, once thought rare, appears to be unexpectedly common across insulating materials. Recent observations in multiple compounds suggest lattice vibrations can carry heat in ways that produce transverse thermal currents even without charge flow, challenging existing theories of heat transport. Researchers are now debating which microscopic mechanisms, from magnetic impurities to phonon Berry curvature, best explain the phenomenon's prevalence.
