Phys.org / Hyena clan rank metrics need to be trait specific to fully explain hierarchies, scientists argue
Spotted hyenas live in hierarchically organized groups (clans). An individual's dominance over another determines priority access to resources such as food or mating partners, and thus reproductive success. However, the rank ...
Phys.org / Scientists unlock evolution of gigantism in Scottish island wrens
A new study of British wrens has provided new insights into the inner workings of "island syndromes," according to research led by the University of Birmingham. The paper, published in the Evolutionary Journal of the Linnean ...
Phys.org / Arctic Ocean food chain is disrupted as a key tipping point has now been passed
An irreversible shift in the chemical makeup of the Arctic Ocean driven by climate change is disrupting the region's food chain, a study suggests. Widespread loss of Arctic sea ice has led to a sharp fall in levels of a key ...
Phys.org / Cells trap heat in ways standard fluid physics cannot explain, study finds
Living cells cool much slower than our current understanding of heat conduction can explain, according to new research from the University of Tokyo. Researchers have used two techniques—high-speed temperature mapping and ...
Phys.org / Astronomers discover how to estimate masses of newborn planets using dust rings
A team of astronomers, led by University of Warwick in collaboration with researchers at MIT and McMaster, have developed a novel method to use the properties of dust rings around stars to estimate the masses of newborn planets. ...
Phys.org / A new approach to urban planning with less car traffic and lower carbon emissions
Urban planning needs to tackle greenhouse gas emissions—and an important way to achieve this is by reducing the number and length of car commutes. This can be achieved primarily by ensuring that homes are located close to ...
Phys.org / Plants select growth strategies by 'spying' on their neighbors' scents
New research reveals that plants have the ability to detect their neighbors' growth rates through aromatic cues called volatile organic compounds (VOCs) and subsequently adjust how much energy they invest into their own growth ...
Phys.org / Listening to the sun reveals previously hidden changes to solar cycle
Internal changes due to the sun's "active biorhythm" have become increasingly "skin-deep" over the past four solar activity cycles, according to a new study.
Phys.org / Newly discovered 'thunder' of Atlantic sturgeons inspires awe
When a team of researchers recorded a low thundering underneath the surface of the Hudson River, they thought they were hearing the muffled rumble of trains. A closer look and listen led to a much more interesting discovery: ...
Phys.org / How the greenhouse effect governs temperature changes across Antarctica
A decade ago, Bradley Markle, an assistant professor at the Institute of Arctic and Alpine Research at the University of Colorado Boulder, noticed an odd pattern while sifting through temperature records from the end of the ...
Phys.org / Temporary carbon removal could help support climate goals, if used correctly
Persistent methane emissions from sectors such as agriculture and growing debates over the credibility of carbon offsets are creating new challenges for governments and companies pursuing net-zero commitments. New research ...
Phys.org / A severed piece of sea cucumber refused to die, and what happened next could transform medicine
From the revived corpse of Frankenstein's monster to the disembodied hand, "Thing," in the Addams Family, reanimated tissue is one of the most enduring images in science fiction. It turns out, that image has some basis in ...
