Calcium bursts kill drug-resistant tumor cells

Multidrug resistance (MDR)—a process in which tumors become resistant to multiple medicines—is the main cause of failure of cancer chemotherapy. Tumor cells often acquire MDR by boosting their production of proteins that ...

Custom fabricated microscope lens inspired by lighthouse

An optical device that resembles a miniaturized lighthouse lens can make it easier to peer into Petri dishes and observe molecular-level details of biological processes, including cancer cell growth. Developed by KAUST, the ...

Scientists grow optical chips in a petri dish

The modern photonics industry is constantly working on making its devices more compact, be it computing systems or sensors and lidars. For this, it is necessary to make lasers, transistors and other elements smaller. A team ...

How life on Earth has evolved underground

Hidden beneath Australia's surface, aquatic ecosystems that have survived in complete isolation for millions of years shed light on the evolution of living and extinct species.

Elon Musk dismisses astronomy concerns over Starlink network

SpaceX founder Elon Musk on Monday dismissed scientists' concerns that his company's Starlink constellation of internet satellites would obscure the view of the night sky, predicting the network "will not cause any impact ...

Directing nanoparticles straight to tumors

Modern anticancer therapies aim to attack tumor cells while sparing healthy tissue. An interdisciplinary team of researchers at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and FU Berlin has made important progress in this ...

A heart-healthy protein from bran of cereal crop

Foxtail millet is an annual grass grown widely as a cereal crop in parts of India, China and Southeast Asia. Milling the grain removes the hard outer layer, or bran, from the rest of the seed. Now, researchers have identified ...
