Phys.org / Land-intensive carbon removal requires better siting to protect biodiversity, study warns
New research looks at carbon dioxide removal—where carbon is absorbed from the atmosphere and stored—and finds that large-scale reliance on land-based methods, such as planting forests or bioenergy with carbon capture ...
Phys.org / Hypothermia risks increase in Mississippi and Tennessee with next wave of frigid temperatures
With another wave of dangerous cold heading for the U.S. South on Friday, experts say the risk of hypothermia heightens for people in parts of Mississippi and Tennessee who are entering their sixth day trapped at home without ...
Phys.org / New 3D map of the sun's magnetic interior could improve predictions of disruptive solar flares
For the first time, scientists have used satellite data to create a 3D map of the sun's interior magnetic field, the fundamental driver of solar activity. The research, published in The Astrophysical Journal Letters, should ...
Phys.org / Fast-growing trees are taking over the forests of the future and putting biodiversity, climate resilience under pressure
Trees play a central role in life on Earth. They store CO₂, provide habitats for animals, fungi, and insects, stabilize soils, regulate water cycles, and supply resources that humans rely on—from timber and food to recreation ...
Phys.org / Record-breaking photons at telecom wavelengths—on demand
A team of researchers from the University of Stuttgart and the Julius-Maximilians-Universität Würzburg led by Prof. Stefanie Barz (University of Stuttgart) has demonstrated a source of single photons that combines on-demand ...
Phys.org / Puzzling slow radio pulses are coming from space. A new study could finally explain them
Cosmic radio pulses repeating every few minutes or hours, known as long-period transients, have puzzled astronomers since their discovery in 2022. Our new study, published in Nature Astronomy today, might finally add some ...
Phys.org / Higher water levels could turn cultivated peatland in the North into a CO₂ sink
In its natural state, peatland is one of the largest carbon stores in nature. This is because the soil is so waterlogged and low in oxygen that dead plant material breaks down very slowly. The plants do not fully decompose ...
Phys.org / Growing meltwater reservoirs—glacial lakes are both a resource and a habitat worthy of protection
Should growing glacial lakes be used for energy production and water supply—or remain protected as ecologically valuable systems? A research team from the University of Potsdam, together with partners from the University ...
Phys.org / Wetlands do not need to be flooded to provide the greatest climate benefit, shows study
Wetlands make up only about 6% of the land area but contain about 30% of the terrestrial organic carbon pool. Therefore, CO2 emissions from wetlands are central to the global climate balance. In Denmark, the plan is to flood ...
Phys.org / Fossilized plankton study gives long-term hope for oxygen-depleted oceans
A new study suggests the world's oxygen-depleted seas may have a chance of returning to higher oxygen concentrations in the centuries to come, despite our increasingly warming climate.
Phys.org / Beyond polymers: New state-of-the-art 3D micro and nanofabrication technique overcomes material limitations
Building things so small that they are smaller than the width of a human hair was previously achieved by using a method called two-photon polymerization, also known as 2PP—today's state-of-the-art in 3D micro- and nanofabrication. ...
Phys.org / Magnetic superhighways discovered in a starburst galaxy's winds
Using the Atacama Large Millimeter/submillimeter Array (ALMA), an international team of astronomers has mapped a magnetic highway driving a powerful galactic wind into the nearby galaxy merger of Arp 220, revealing for the ...
