Phys.org / Alzheimer's-linked protein tau plays a role in cell division
All processes such as wound healing, hair growth, and the replacement of old cells with new ones depend on cell division. During this process, chromosomes inside the cell must be evenly divided between two daughter cells. ...
Phys.org / Why the phrase 'Super El Niño' makes Australian climate scientists roll their eyes
Frightening headlines predicting a Super El Niño or even a Godzilla El Niño amp up anxiety levels for farmers and residents of bushfire-prone regions.
Phys.org / Climate change may speed evolution through inherited gene regulation changes
A new paper in Molecular Biology and Evolution, finds that changes in animal development induced by climate shock persist generations after the initial event. The escalating effects of climate change are likely to, in effect, ...
Phys.org / New spider species in the Amazon mimics parasitic fungus
An international research team, including the Leibniz Institute for the Analysis of Biodiversity Change (LIB), has described a new species of spider from the Ecuadorian Amazon: Taczanowskia waska. The species is characterized ...
Phys.org / Ancient Māori remains point to largely plant-based diets before colonization
New research led by the University of Otago—Ōtākou Whakaihu Waka, in close partnership with mana whenua, is shedding new light on Māori diet and burial practices in Aotearoa New Zealand prior to European colonization. The ...
Phys.org / Non-producing oil and gas wells may emit microbial methane at rates 1,000 times higher than previously estimated
Microbial methane leaking from non-producing oil and gas wells is being emitted at rates about 1,000 times higher than previously estimated, according to a new study led by McGill University researchers. "Origins of Subsurface ...
Phys.org / Inquiry-based biomimicry course inspires students to design solutions by learning from nature
Research and innovation in Texas A&M University's biomedical engineering department often centers around clinical impact on patients. Beyond the lab, however, some faculty are finding breakthroughs in the classroom.
Phys.org / Tarantulas may use learning and memory to search for food and locate their retreats
Researchers have documented several cases of spatial orientation in tarantulas living both in trees and in underground burrows. Spatial orientation refers to the ability of an animal to understand where it is in three-dimensional ...
Phys.org / Early humans in South Africa were quarrying stone as far back as 220,000 years ago
As long as 220,000 years ago—far earlier than previously thought—people quarried rocks for their tools in places they specifically sought out. An international research team led by the University of Tübingen has demonstrated ...
Phys.org / Alignment during conversations is highly situation-dependent, study finds
When people are talking, they can start to unconsciously mirror each other, for instance, in the words they use, their sentence structures and even hand gestures. This tendency to mirror others can lead to smoother conversations, ...
Medical Xpress / Little-used cholesterol test could prevent more heart attacks and strokes
A routine blood test taken by millions in the U.S. each year to measure "bad" cholesterol is not the best measure to guide treatment and prevent heart attacks and strokes, suggests a new Northwestern Medicine study published ...
Medical Xpress / COVID-19's lingering shadow: The molecular link between SARS-CoV-2 and lung cancer risk
A new study suggests that COVID-19 may slightly increase the risk of lung cancer by triggering a biological chain reaction in the lungs, driven by the virus's spike protein, that promotes inflammation, scarring, and tumor-friendly ...
