These results are preliminary, but they could eventually improve ovarian health and fertility in women, researchers say
Snakes may be best known for slithering. But consider that these animals also perform one of the most extreme feats of posture control found in nature: They can stand nearly straight upright on a narrow perch without falling, lifting 70% of their body length, despite having no
Few pests eat away at farm profitability as much as soybean cyst nematode (SCN). Causing at least $1.5 billion in yield losses annually, it's soybean's single biggest threat. Unfortunately, soybean's most effective tool, genetic resistance, is starting to fail. That's why a
Many large herbivores that once roamed modern-day Panama have declined or died out—including the 6-meter-long giant ground sloth and elephant-related creatures called Cuvieronius. New research suggests that introducing large herbivores in Panama's forests could fill the gap
Hologram AI concert experiences may look futuristic, with their computer-generated 3D illusions of dead artists performing on stage. But research from the University of South Florida shows their success depends on something very human: ethics, trust and emotional connection.
Researchers have found that the size of the amygdala—a region of the brain involved in processing emotions—could be linked to social tolerance in macaque monkeys. Their research, published today in eLife, is described by the editors as important work with a convincing
A family in Utah with a disproportionate number of boys has been traced back over hundreds of years, revealing that its lack of female members is probably due to a selfish Y chromosome
At the paleontology conference, her new theory was shouted down The post When Scientists Are Dinosaurs appeared first on Nautilus .
A study involving the UAB has analyzed the effect of foreign trade and immigration on the success of both right- and left-wing populist parties. The analysis reveals how the importation of products that require low-skilled labor plays a key role in the rise of both types of
One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object's physical state being measured—and therefore also the outcome of any subsequent measurement. How fast
Floodplains face increasing pressure: currently protected areas will not be sufficient to preserve the species living in them in the future, a review study conducted under the direction of the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) shows.
Almost all plants live in close symbiosis with so-called mycorrhizal fungi—an important symbiosis for absorbing essential nutrients. In their new study, a team led by ecologist Christina Kaiser from the Center for Microbiology and Environmental Systems Science (CeMESS) at the
Scientists have identified a crucial molecular switch that decides whether pancreatic cancer cells resist chemotherapy or respond to it. The key player, a gene called GATA6, keeps tumours in a more structured and treatable form—but it gets shut down by an overactive KRAS-driven
After more than 25 months of successful operations in space, the SpIRIT mission has ended, marking a major milestone for Australia's growing space capability. Led by the University of Melbourne, in collaboration with the Italian Space Agency, the Space Industry Responsive
To uncover the history of our solar system, it is necessary to study the dynamic evolution of the ancient solar nebula materials. These materials interacted and coevolved with the weak but widespread magnetic field of the solar nebula, which was generated by the weakly ionized
Don’t worry if you missed Tuesday’s total lunar eclipse. These images show the celestial marvel from around the world
From the cost of childcare to the housing crisis, there’s no shortage of explanations for the dramatic global fall in the number of babies being born. These analyses, though, are all missing something, says cognitive and evolutionary anthropologist Paula Sheppard
The microbes that live in our mouth and gut may influence whether an allergic reaction to peanuts is mild or life-threatening, and could be harnessed to ward off a severe attack
When you reach the bottom of a container of milk or honey, you might be tempted to tip the container over to get that last pesky little bit out. After all, you only need another teaspoon for that recipe, and you're sure it's in there. From emptying jars to drying dishes,
Lucid dreamers who heard puzzle-linked soundtracks while sleeping were more likely to solve those unsolved problems the next day.
Past civilizations have been significantly affected by climate change, but how they adapted to new conditions centuries ago is less clear. In research newly published in the Proceedings of the National Academy of Sciences, a team of archaeologists and geographers describes a
For decades, scientists have mapped attention, memory, language, and reasoning to separate brain networks — yet one big mystery remained: why does the mind feel like a single, unified system? Researchers at the University of Notre Dame now suggest that intelligence doesn’t live
Left-handers are more competitive than right-handers, according to a new study published in the journal Scientific Reports. The findings may help explain why left-handedness has persisted throughout evolution despite the majority of people being right-handed.
UC College of Arts and Sciences Professor Thomas Algeo has been studying the planet's five major mass extinctions since the Ordovician Period, when global sea levels were much higher than today. In a paper published in Nature Ecology & Evolution, Algeo provides context for a
