Two-photon gates.
Researchers at University of Washington have developed a deterministic, high-fidelity two-bit quantum logic gate that takes advantage of a new form of light. This new logic gate is orders of magnitude more efficient than the current technology.
Their advance is recorded in Physical Review A: http://dx.doi.org/10.1103/PhysRevA.103.052610

Two-photon controlled-phase gates enabled by photonic dimers
Photons are appealing as flying quantum bits due to their low-noise, long coherence times, light-speed transmission, and ease of manipulation at the single-qubit level using standard optical components such as beam splitters and waveguides. The challenge…
Seabirds depleting fish.
University of Exeter research shows that the seabird colony on Ascension Island creates a halo in which fewer fish are found. Reduced numbers of flying fish were found up to 90 miles from the island. The study provides insights into how large colonies of animals are naturally limited in number.
Their insights can be read in PNAS: http://dx.doi.org/10.1073/pnas.2101325118

Direct evidence of a prey depletion “halo” surrounding a pelagic predator colony
Elucidating the mechanisms that regulate animal populations is a fundamental goal in ecology and is increasingly important at a time of unprecedented anthropogenic disturbance to ecosystems. Here, we present direct evidence of a phenomenon known as “Ashmole’s…
Shrinking dinosaurs.
Paleontologists at the University of Bristol have explained how changes in the diet of dinosaurs lead to a rapid shrinking of their sizes. The dietary changes were likely caused by a changing environment and competitive pressure for resources.
Their theories are described in Current Bbiology: https://www.sciencedirect.com/science/article/abs/pii/S0960982221008083

Topological excitations and bound photon pairs in a superconducting quantum metamaterial
Topological photonics enables resilient routing and localization of light. Of special interest are topological states of quantum light promising disorder-robust quantum correlations. Here, the authors design and fabricate a one-dimensional dimerized array…
Artificial organelles.
Organelles are components of cells that individually perform complex biochemical reactions. Researchers at the 기초과학연구원(IBS, Institute for Basic Science) have constructed artificial organelles that could supply ATP or other useful molecules to damaged or diseased tissue cells.
The work is reported in Nature Catalysis: https://www.nature.com/articles/s41929-021-00669-z

Molecular mechanisms in brain diseases.
Regulation of cellular proteins is crucial for maintaining a healthy brain. Rutgers University scientists have developed insights into how toxic proteins are regulated in neurodegenerative conditions such as Alzheimer’s and Parkinson’s diseases, which could help to design effective treatments in future.

Stress increases in exopher-mediated neuronal extrusion require lipid biosynthesis, FGF, and EGF RAS/MAPK signaling
In neurodegenerative disease, protein aggregates spread to neighboring cells to promote pathology. The in vivo regulation of toxic material transfer remains poorly understood, although mechanistic understanding should reveal previously unrecognized therapeutic…
Sparkling cluster galaxy.
The Hubble Space Telescope’s Wide Field Camera 3 and the Advanced Camera for Surveys have been used to capture an image of the NGC 6717 galaxy. Located 20,000 light-years from Earth in the constellation Sagittarius, NGC 6717 is a spherical grouping of stars held together by gravity.
