New study of how bacteria swim could help prevent the spread of disease and improve medical treatments
For years, science fiction authors have written about the idea of using microswimmers that could perform surgeries or deliver medicines to humans. Now, a team led by University of Minnesota Twin Cities researchers discovered how bacteria swim through.....»»
Unraveling the mystery of parrot longevity
Parrots are famous for their remarkable cognitive abilities and exceptionally long lifespans. Now, a study led by Max Planck researchers has shown that one of these traits has likely been caused by the other. By examining 217 parrot species, the rese.....»»
Biodiversity conservation requires large and strictly protected areas
Size matters when it comes to preserving biodiversity in natural areas. Larger and strictly protected areas are clearly more effective, according to biologists from Utrecht University and international colleagues. Examining the biodiversity of more t.....»»

An international team with participation of the University of Bern provides new insights about how the inhabitants of the "oldest city in the world" in Çatalhöyük (Turkey) buried their dead. Their bones were partially painted, excavated several ti.....»»
Collectors in the prehistoric world recycled old stone tools to preserve the memory of their ancestors
A first-of-its-kind study at Tel Aviv University asks what drove prehistoric humans to collect and recycle flint tools that had been made, used, and discarded by their predecessors. After examining flint tools from one layer at the 500,000-year-old p.....»»
Examining how animal swarms respond to threats
A herd of antelope feeds peacefully on a meadow. Suddenly, a lion shows up, and the herd flees. But how do they manage to do so collectively? Konstanz physicist Chun-Jen Chen and Professor Clemens Bechinger, a member of the Cluster of Excellence "Cen.....»»
Earthquake fracture energy relates to how a quake stops
By examining earthquake models from a fresh perspective, Cornell engineers now show that the earthquake fracture energy—once thought to relate to how faults in the Earth's crust weaken—is related to how quakes stop......»»

Harmless or deadly? Examining the evolution of E. coli
Genetic material from E. coli bacteria in farm animals could be contributing to the evolution of deadly pandemic strains of E. coli in humans, new research shows......»»
How do marine gases affect cloud formation?
Studying the global climate—and how it's changing—involves examining thousands of small processes, chemical mechanisms, local weather phenomena, and more. One of the many factors scientists consider when studying the changing climate is aerosols,.....»»
Examining the deterrence effect of whistleblowing
Whistleblowers are not only helping to disclose immoral or criminal acts but also to deter offenders. Niels Johannesen, an economics professor from the University of Copenhagen and Tim Stolper, a former research associate at the Max Planck Institute.....»»
Study spearheads the chemical fingerprint of Viking weapons

Examining the results of new dark matter searches by the PandaX-4T and ADMX collaborations
Physicists have predicted the existence of dark matter, a material that does not absorb, emit or reflect light, for decades. While there is now significant evidence hinting to the existence of dark matter in the universe, as it was never directed det.....»»
Examining why locusts form destructive swarms
Researchers at Tel Aviv University found that the microbiome of a solitary locust undergoes a profound change when the host joins a group: bacteria called Weissella, almost completely absent from the microbiome of solitary locusts, become dominant in.....»»

Research in mice identifies neurons that control locomotion
For more than a century, scientists have known that while the commands that initiate movement come from the brain, the neurons that control locomotion once movement is underway reside within the spinal cord. In a study published January 20 in the jou.....»»
Examining tiny cells surrounding the smallest blood vessels in the brain
One of the laboratories at the Institute of Basic Medical Sciences houses equipment worth many millions of kroners. Few research groups have the resources to buy an electron microscope when conducting scientific research. Using an electron microscope.....»»
Examining electron transport shuttles in microorganisms
Every living thing requires energy. This is also true of microorganisms. Energy is frequently generated in the cells by respiration, that is, by the combustion of organic compounds—in other words, food. During this process, electrons are released,.....»»
