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 / 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 / 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 / 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 / Research uncovers novel electronic properties in quantum material
Florida State University physicists are part of a team that has discovered unusual superconducting states in parts of graphene, with the potential to drive unexpected quantum technologies.
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 ...
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 / 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 / Twisted stacking lets 2D conductor keep single-layer performance in bulk form
Two-dimensional (2D) materials, which are significantly thinner than a single sheet of paper, have long drawn attention for their exceptional performance. However, they have faced a critical limitation: Their performance ...
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 / 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 / Gleam-glum effect reveals emotional word cues in children as young as five
The words "tick-tock," "hiss" and "screech" are examples of onomatopoeia because they imitate the sounds they represent: the rhythmic ticking of a clock; an angry cat, or a slowly deflating bike tire; a high-pitched scream. ...
