Phys.org / 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 ...
Phys.org / Cosmic dust could play key role in cracking long-standing mystery of solar corona heating
A researcher at The University of Alabama in Huntsville (UAH), a part of The University of Alabama System, has published a new study in The Astrophysical Journal suggesting that tiny charged dust grains near the sun may significantly ...
Medical Xpress / What is mild cognitive impairment? And does it always lead to dementia?
You've forgotten a few appointments lately, and you find yourself losing track of conversations. Close friends or family may have also noticed some changes in your memory or thinking.
Phys.org / Complex food webs sustain ecosystem functioning
Healthy ecosystems depend on more than just having lots of species—they rely on the complex relationships between plants, prey and predators, according to new international research led by the University of Waikato and the ...
Phys.org / Climate change will raise the risk of severe heat waves: New Zealand homes aren't ready
Europe's summer heat wave has exposed tens of millions of people to temperatures above 35°C, broken records and claimed hundreds of lives. Early climate attribution studies suggest Europe's event would have been "virtually ...
Phys.org / Were Clovis foragers in Late Pleistocene North America big-game hunters, or just big-game scavengers?
There are currently 15 well-documented Late Pleistocene localities in North America in which Clovis points are found associated with proboscidean remains (of mammoth, mastodon and gomphothere). Archaeologists routinely assume ...
Phys.org / Primate brains might have evolved to 'catch up' with larger bodies, but then kept growing
A new analysis supports the previously overlooked "brain lag" hypothesis—the idea that, in some primate lineages, the evolution of larger body size preceded the evolution of larger brain size—while also building on that hypothesis ...
Medical Xpress / The circuit that lets your brain think and see
Nuttida Rungratsameetaweemana is challenging a story neuroscience has told for decades. According to the conventional account, our eyes collect raw information and relay it through a series of nerves and waystations that ...
Phys.org / Lake Chad supports 2.48 million waterbirds, emerging as one of Africa's top wetland refuges
A study titled "Monitoring major biodiversity stronghold in war zones: model predicts Lake Chad remains Africa's most important wetland for waterbirds" estimates that Lake Chad supports nearly 2.5 million waterbirds, making ...
Phys.org / Sea turtles diving through the eye of the storm help develop better cyclone forecasts
Every summer, communities across northern Australia brace for the tropical cyclone season. Tropical cyclones draw their power from the warm seas, extracting heat and moisture from ocean water.
Phys.org / Ph.D. project gives critical insights into vulnerable green turtles
A study into the foraging habits of green turtles in the Northern Territory has used an innovative surveying technique that could become a critical tool in monitoring marine habitats in remote and challenging environments.
Phys.org / Sun-powered sponges may generate 11% of tropical coral reef productivity
In marine environments, sponges tend to eat other organisms to get their nutrients. But a study published in Functional Ecology by researchers at the University of Amsterdam's Institute for Biodiversity and Ecosystem Dynamics ...
