N-channel diamond field-effect transistor      (via sciencedaily.com)     Original source 

A research team has developed an n-channel diamond MOSFET (metal-oxide-semiconductor field-effect transistor). The developed n-channel diamond MOSFET provides a key step toward CMOS (complementary metal-oxide-semiconductor: one of the most popular technologies in the computer chip) integrated circuits for harsh-environment- applications as well as the development of diamond power electronics.

Forest, stream habitats keep energy exchanges in balance, global team finds      (via sciencedaily.com)     Original source 

Forests and streams are separate but linked ecosystems, existing side by side, with energy and nutrients crossing their porous borders and flowing back and forth between them. For example, leaves fall from trees, enter streams, decay and feed aquatic insects. Those insects emerge from the waters and are eaten by birds and bats. An international team has now found that these ecosystems appear to keep the energy exchanges in balance -- a finding that the scientists called surprising.

AI can now detect COVID-19 in lung ultrasound images      (via sciencedaily.com)     Original source 

Artificial intelligence can spot COVID-19 in lung ultrasound images much like facial recognition software can spot a face in a crowd, new research shows. The findings boost AI-driven medical diagnostics and bring health care professionals closer to being able to quickly diagnose patients with COVID-19 and other pulmonary diseases with algorithms that comb through ultrasound images to identify signs of disease.

Quantum talk with magnetic disks      (via sciencedaily.com)     Original source 

Quantum computers promise to tackle some of the most challenging problems facing humanity today. While much attention has been directed towards the computation of quantum information, the transduction of information within quantum networks is equally crucial in materializing the potential of this new technology. Addressing this need, a research team is now introducing a new approach for transducing quantum information: the team has manipulated quantum bits, so called qubits, by harnessing the magnetic field of magnons -- wave-like excitations in a magnetic material -- that occur within microscopic magnetic disks.

Decoding the Easter Bunny -- an eastern Finnish brown hare to represent the standard for the species' genome      (via sciencedaily.com)     Original source 

Biologists have published a chromosomally assembled reference genome for the European brown hare. The genome consists of 2.9 billion base pairs, which form 23 autosomal chromosomes, and X and Y sex chromosomes. The timing of the genome release is very appropriate as the brown hare also represents the original Easter Bunny familiar from European folklore.

Why do tree frogs lay their eggs on the ground?      (via sciencedaily.com)     Original source 

A curious aspect of tree frogs is that they often lay their eggs on the ground where the risk of predation by natural enemies is greater than in the trees where they live. A research team suggested that the reason for this behavior is to protect the eggs from low temperatures. Their findings highlight the challenge faced by tree frogs: Should they attempt to maintain an optimal temperature for their eggs or risk predation?

Tropical birds could tolerate warming better than expected, study suggests      (via sciencedaily.com)     Original source 

We expect tropical animals to handle a certain degree of heat, but not wild swings in temperature. That seems to be true for tropical ectotherms, or 'cold-blooded' animals such as amphibians, reptiles, and insects. However, in a new study of 'warm-blooded' endotherms, a research team found tropical birds can handle thermal variation just fine.
