The Darwinian diet: You are what you eat

Imagine millions of leafcutter ants on parade through a tropical forest. Driven by a craving mysterious to humans, they suddenly stream up a towering tree trunk. How do they know exactly which species of leaves to cut for ...

NATO to set up new space center amid China, Russia concerns

To a few of the locals, the top-secret, fenced-off installation on the hill is known as "the radar station." Some folks claim to have seen mysterious Russians in the area. Over the years, rumors have swirled that it might ...

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 ...

Sound waves replace human hands in petri dish experiments

Mechanical engineers at Duke University have demonstrated a set of prototypes for manipulating particles and cells in a Petri dish using sound waves. The devices, known in the scientific community as "acoustic tweezers," ...

Sampling the gut microbiome with an ingestible pill

Gut microbes affect human health, but there is still much to learn, in part because they're not easy to collect. But researchers now report in ACS Nano that they have developed an ingestible capsule that in rat studies captured ...

Understanding the circadian clocks of individual cells

Two new studies led by UT Southwestern scientists outline how individual cells maintain their internal clocks, driven both through heritable and random means. These findings, published online May 1 in PNAS and May 27 in eLife, ...

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 ...
