Decline of diatoms due to ocean acidification
- ScienceDaily
- 22/5/26 00:26
Diatoms are the most important producers of plant biomass in the ocean and help to transport carbon dioxide (CO2) from the atmosphere into the deep ocean and thus regulate our climate. Because diatoms rely on silica rather than calcium carbonate to build their shells, they were previously thought to benefit from ocean acidification -- a chemical change in seawater triggered by the increasing...

Tiny robotic crab is smallest-ever remote-controlled walking robot
- ScienceDaily
- 22/5/25 21:17
Engineers have developed the smallest-ever remote-controlled walking robot -- and it comes in the form of a tiny, adorable peekytoe crab. Just a half-millimeter wide, the tiny crabs can bend, twist, crawl, walk, turn and even jump. Although the research is exploratory at this point, the researchers believe their technology might bring the field closer to realizing micro-sized robots that can...
Secrets of thymus formation revealed
- ScienceDaily
- 22/5/25 19:12
Scientists have identified processes that control the development and composition of thymic tissue throughout life. Specifically, they were able to show that a certain growth factor can maintain progenitor cells even in the aging thymus and thus counteract the age-related shrinkage of the organ and the reduction in the number of powerful immune cells. The results provide new avenues for...
Artificial cilia could someday power diagnostic devices
- ScienceDaily
- 22/5/25 19:12
Researchers have now designed a micro-sized artificial cilial system using platinum-based components that can control the movement of fluids at such a scale. The technology could someday enable low-cost, portable diagnostic devices for testing blood samples, manipulating cells or assisting in microfabrication processes.
Physicist uses intuition, supercomputers to identify new high-temperature superconductor
- ScienceDaily
- 22/5/25 19:12
In 2021, scientists discovered a new form of superconducting nickelate using computational methods. The discovery lets researchers explore similarities and differences between nickelates and cuprates -- promising copper-based materials -- and among nickelates. Both families of materials appear to display 'super-exchange,' where the material trades electrons in copper or nickel atoms through a...
Study reveals cause, potential precision therapies for aggressive type of lymphoma
- ScienceDaily
- 22/5/25 19:11
DNA mutations are essential to the rapid development of an array of antibody-producing immune cells called B cells that collectively can recognize a vast number of specific targets. But this process can go awry in people with a mutation in a gene called SETD2, leading to a type of aggressive blood cancer, according to a new study.
Researchers teleport quantum information across rudimentary quantum network
- ScienceDaily
- 22/5/25 19:11
Researchers have succeeded in teleporting quantum information across a rudimentary network. This first of its kind is an important step towards a future quantum Internet. This breakthrough was made possible by a greatly improved quantum memory and enhanced quality of the quantum links between the three nodes of the network.
Archaeologists reveal pre-Hispanic cities in Bolivia with laser technology
- ScienceDaily
- 22/5/25 17:09
Several hundred settlements from the time between 500 and 1400 AD lie in the Bolivian Llanos de Mojos savannah and have fascinated archaeologists for years. Researchers have now visualized the dimensions of the largest known settlement of the so-called Casarabe culture. Mapping with the laser technology LIDAR indicates that it is an early urbanism with a low population density -- the only known...
Scientists identify how the brain links memories
- ScienceDaily
- 22/5/25 17:09
Our brains lose the ability to link related memories as we age. Scientists genetically restored this brain function in middle-aged mice and identified an FDA-approved drug that achieves the same thing. The study suggests a new approach for combating middle-aged memory loss and a possible early intervention for dementia.
Roboticists go off road to compile data that could train self-driving ATVs
- ScienceDaily
- 22/5/25 17:09
Researchers took an all-terrain vehicle on wild rides through tall grass, loose gravel and mud to gather data about how the ATV interacted with a challenging, off-road environment. They drove the heavily instrumented ATV aggressively at speeds up to 30 miles an hour. They slid through turns, took it up and down hills, and even got it stuck in the mud -- all while gathering data such as video, the...
Climate change reveals unique artifacts in melting ice patches

Norwegian mountains are full of time capsules. Thousands of years of human and ecological history are preserved in remnant patches of ice. Now this treasure trove of information threatens to melt away, unless we take action.
High air pollution from fracking in Ohio county
- ScienceDaily
- 22/5/25 17:09
Residents of Belmont County in eastern Ohio have long suffered from health problems they suspected were the result of air pollution from fracking facilities, but regulators dismissed and downplayed their concerns. With technical assistance from volunteer scientists, local advocacy groups set up their own network of low-cost sensors. They found that the region's three EPA sensors were not providing...
Silicone wristbands track firefighters' exposures to harmful chemicals
- ScienceDaily
- 22/5/25 17:09
Researchers have used silicone wristbands to track firefighters' exposures to 134 potentially carcinogenic chemicals. Analysis of the chemicals absorbed by the wristbands over a six-day shift show that while some exposures are linked to being at the scene of a fire, others aren't. This suggests that just being a firefighter means you are exposed to more of these compounds than the average adult,...
