Phys.org / Antibiotics drive resistance in waterways—even after they break down
Antibiotics continue to drive resistance in bacteria, even after they are broken down in wastewater treatment plants and discharged into rivers and seas, new research published on World Oceans Day has shown for the first ...
Phys.org / Brazilian breadbasket's aquifers are falling, and new satellite maps show where water stress is growing
A collaboration of scientists from NASA and Brazilian research institutions has produced a detailed picture of groundwater change across Brazil. The images reveal significant declines in some of the aquifers that are critical ...
Phys.org / Peptide blocks DNA breaks tied to treatment-induced leukemia, offering new prevention route
Thanks to effective therapies, more and more people are now able to live with or after cancer in the long term. Consequently, the number of patients affected by the long-term effects of their treatment is also increasing. ...
Dialog / A 170 km journey by a freshwater stingray challenges long-held conservation assumptions
Most sharks and rays inhabit the oceans, but a small proportion thrive in freshwater. Approximately 4% to 5% of all shark and ray species live in tropical and subtropical rivers around the world. Two main ecological strategies ...
Phys.org / Magnesium transporter discovery could improve rice nutrition and taste
Rice is a staple food for nearly half the global population and an important dietary source of magnesium, a mineral essential for human health, plant growth and energy metabolism. Although magnesium is known to influence ...
Phys.org / Satellites reveal cities' 'urban pulse,' tracking neighborhood growth in near real time
For over a century, doctors have used electrocardiograms (EKGs) to render the invisible electrical activity of the human heart visible, using the pulse to diagnose disease before it becomes fatal. Now, scientists have invented ...
Phys.org / Van der Waals forces can play unexpected role in thin film properties
Researchers have demonstrated the ability to use van der Waals forces to tune the physical and electronic properties of ferroelectric thin films. The work opens the door to new techniques for engineering materials for use ...
Phys.org / NASA satellites reveal major ocean nutrient stress
A new study combining NASA satellite observations, ocean surveys and genetic testing of marine microorganisms found evidence that warming ocean waters may be limiting nutrient availability across much of the global ocean. ...
Phys.org / Ocean collapse triggered ancient wildfires, research suggests
Research led by the University of Alabama found that widespread wildfires during one of Earth's ancient environmental crises did not trigger an ocean collapse but were a consequence of it.
Phys.org / New cryogenic silicon carbide hardware addresses quantum computing bottleneck
Researchers from the Department of Electrical and Computer Engineering in the Faculty of Engineering at the University of Hong Kong (HKU) and the Centre for Advanced Semiconductors and Integrated Circuits (CASIC) have achieved ...
Phys.org / Alien signal claims face stricter verification under updated disclosure rules
The IAA SETI Committee has updated rules for evaluating and revealing the detection of extraterrestrial intelligence.
Phys.org / Plants could be used to grow medicines in space, study shows
Astronauts on long space missions may one day use plants to produce fresh stocks of medicines on demand, thanks to new research by engineers at the University of California San Diego. The team developed a simple method to ...
