How giant earthquakes can form at fault planes where theory says they should not
A research group led by Satoshi Ide from the University of Tokyo has demonstrated that classic earthquake generation theory does not hold in areas where the angle at which a tectonic plate dips under another is sufficiently low. The discovery explains why giant earthquakes can fo
Ancient gum disease may have helped reshape jaws before human brains expanded
Human evolution is generally explained through changes in brain size, locomotion or tool use, but new research from Wits University suggests that gum disease and changes in facial structure may have been important factors in shaping the evolutionary path that ultimately led to mo
Scientists reveal what really happens when water is trapped in tiny spaces
A decades-old puzzle about water has finally been unraveled. Researchers found that water trapped in tiny nanoscale spaces is not inherently more reactive. Instead, the intense pressures created inside these microscopic gaps explain most of the effect, while the surrounding mater
Quantum gravity tests may mistake ordinary spacetime for superposition
Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful theories of physics: quantum mechanics and gravity. Quantum mechanics explains the behavior of the microscopic world, while Einstein's theory of gravity describes
Deliberate slow growth could explain bacteria survival strategies
Escherichia coli (E. coli) are mostly harmless bacteria that live in the intestines of animals and humans. They are the most well-studied bacteria and, often, when scientists discover something about E. coli, they extrapolate that discovery across all bacteria. So when scientists
Modern life may be outpacing the human mind
The human brain evolved for a world of familiar faces, immediate threats and small social groups. But the world around us is changing far faster than human biology can keep pace. That mismatch may help explain some of the stress, loneliness and constant comparison people experien
Hantaviruses may have co-evolved with rodents for ages, helping explain silent spread
What does a hantavirus do inside its rodent hosts? How do these viruses move through animal populations? And how is it that they cause almost no apparent symptoms in rodents, yet can be nearly fatal in humans? Specially Appointed Professor Hiroaki Kariwa has been studying hantavi
A strange LIGO signal could reveal the missing link behind dark matter
An unusual gravitational wave signal has renewed hopes that primordial black holes, long considered purely theoretical, may finally be within reach of discovery. If confirmed, they could solve one of astronomy's greatest mysteries by explaining the nature of dark matter.
UK temperatures forecast to exceed 30C as another heatwave imminent
Another heatwave is on its way and set to last significantly longer as Stav Danaos explains. O recorte ajuda a contextualizar a pauta dentro de Agro.
Common nanostructures may explain shared photoproperties in two widespread dark materials
A newly developed framework for understanding the photoproperties of both natural organic matter and eumelanin, a natural pigment responsible for dark colors in organisms, may inspire advanced sustainable technologies, scientists say.
How proteins are inserted into cell membranes
Researchers from Heinrich Heine University Düsseldorf (HHU) have—in collaboration with colleagues from Ludwig Maximilian University (LMU) in Munich—analyzed the complex biochemical processes that bacteria use to insert proteins into their cell membranes. They explain that—contrar
