Phys.org / Cloud-tested quantum noise model predicts superconducting qubit errors with sevenfold better accuracy
Researchers from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, and Johns Hopkins University in Baltimore have developed a practical, comprehensive noise-modeling framework for a popular class of ...
Phys.org / River wildlife moves freely once dams are removed, but so too can invasive species
Almost a quarter of all freshwater species are threatened with extinction. The removal of human-made barriers from rivers, such as dams and weirs, is a popular way to restore water flow and sediment transport to its natural ...
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 / Rocket launches and reentries harm Earth's ozone layer
The space industry is surging. In coming years, nearly 10,000 spacecraft are slated to launch into low-Earth orbit for a variety of purposes, such as global surveillance, space tourism, and satellite "megaconstellations" ...
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. ...
Phys.org / Chemists unlock first total synthesis of rare plant alkaloid tied to anticancer activity
Plants are undeniably one of nature's most promising sources of new medicines, with monoterpenoid indole alkaloids (MIAs) being a great example. Some intricate compounds are built from multiple-linked chemical units that ...
Phys.org / Aerosols may warm or cool the climate depending on timing, new study finds
A new study from the Hebrew University of Jerusalem challenges a long-held assumption in climate science by showing that aerosols—tiny particles suspended in the atmosphere—can either warm or cool the climate, depending on ...
Phys.org / California's tectonic stress has reached record level, earthquake model reveals
Earthquakes usually occur along fracture zones in Earth's crust, where large tectonic plates slide past one another and become locked. Stress builds up over long periods and is suddenly released in the form of an earthquake. ...
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 / Elusive Cozumel dwarf fox reappears in first confirmed photos after two decades
A publication has revealed the first photographic evidence and confirmed sighting of the Cozumel dwarf fox in more than 20 years. Published in the journal Neotropical Biology and Conservation by researchers Travis D. Bayer, ...
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 / Ancient hominins selected basalt sources for specific tools nearly 800,000 years ago, study reveals
A new study finds that ancient hominins nearly 800,000 years ago deliberately selected specific basalt sources for different stages of tool production rather than simply using whatever stone was available nearby. By tracing ...
