Immunization of macaques with nanoparticle-conjugated receptor-binding domain of SARS-CoV-2 adjuvanted with 3M-052 and alum results in cross-neutralizing antibodies against bat coronaviruses, SARS-CoV and SARS-CoV-2 variants, and may provide a platform for developing pan-coronavirus vaccines.

It is challenging to store the exponentially increasing amount of data in the information age. The multiplexed optical data storage with merits of high data density (hundreds of terabytes/disk), low energy consumption, and long lifetime could open a new era in data storage technology. The recent progress in five-dimensional (5D) optical data storage based on anisotropic nanostructures written by femtosecond (fs) laser pulses in transparent materials reveals its potential for real-world applications, but high writing speed and density remain a major challenge. Here, we propose a method for rapid and energy-efficient writing of highly localized anisotropic nanostructures in silica glass by energy modulated megahertz-rate fs pulses. An isotropic nanovoid is initially generated with pulse energy above the microexplosion threshold and then elongated to an anisotropic nanolamella-like structure via the near-field enhancement effect by lower energy pulses, minimizing the unwanted thermal effects from megahertz-rate fs pulses. The anisotropic nanostructures are exploited for 5D data storage with a rate of 106voxels/s, corresponding to a demonstrated fast information recording of ∼225kB/s and a potentially high-density data storage of ∼500TB/disk.

3D solar towers circa 2016.

Improving Efficiency

Most solar panels are placed flat on rooftops because they are designed to harness solar energy when the sun is directly overhead. However, when the angle of the sun’s rays hitting the panel changes, traditional panels quickly become less efficient.

Topology in optics and photonics has been a hot topic since 1,890 where singularities in electromagnetic fields have been considered. The recent award of the Nobel prize for topology developments in condensed matter physics has led to renewed surge in topology in optics with most recent developments in implementing condensed matter particle-like topological structures in photonics. Recently, topological photonics, especially the topological electromagnetic pulses, hold promise for nontrivial wave-matter interactions and provide additional degrees of freedom for information and energy transfer. However, to date the topology of ultrafast transient electromagnetic pulses had been largely unexplored.

In their paper published in the journal Nature Communications, physicists in the UK and Singapore report a new family of electromagnetic pulses, the exact solutions of Maxwell’s equation with toroidal topology, in which topological complexity can be continuously controlled, namely supertoroidal topology. The electromagnetic fields in such supertoroidal pulses have skyrmionic structures as they propagate in free space with the speed of light.

Skyrmions, sophisticated topological particles originally proposed as a unified model of the nucleon by Tony Skyrme in 1,962 behave like nanoscale magnetic vortices with spectacular textures. They have been widely studied in many condensed matter systems, including chiral magnets and liquid crystals, as nontrivial excitations showing great importance for information storing and transferring. If skyrmions can fly, open up infinite possibilities for the next generation of informatics revolution.

Trees make everything better. Even EV batteries.

Trees provide the air we breathe, and now, in an interesting turn of events, they might also help to power our electronics. A team of researchers from Brown University and the University of Maryland developed a new material that can be used in solid-state batteries to improve the safety and power of traditional batteries by replacing the liquids typically used in lithium-ion cells, a press statement reveals.

The material in question is a kind of cellulose nanofibril, which takes the form of polymer nanotubes derived from wood. The researchers found that it could be combined with copper to produce a paper-thin material that has an ion conductivity between 10 and 100 times better than other polymer ion conductors.

In a major breakthrough, researchers at Massachusetts General Hospital (MGH) have discovered how amyloid beta — the neurotoxin believed to be at the root of Alzheimer’s disease (AD) — forms in axons and related structures that connect neurons in the brain, where it causes the most damage. Their findings, published in Cell Reports, could serve as a guidepost for developing new therapies to prevent the onset of this devastating neurological disease.

Among his many contributions to research on AD, Rudolph Tanzi, PhD, vice chair of Neurology and co-director of the McCance Center for Brain Health at MGH, led a team in 1986 that discovered the first Alzheimer’s disease gene, known as APP, which provides instructions for making amyloid protein precursor (APP). When this protein is cut (or cleaved) by enzymes — first, beta secretase, followed by gamma secretase — the byproduct is amyloid beta (sometimes shortened to Abeta). Large deposits of amyloid beta are believed to cause neurological destruction that results in AD. Amyloid beta formed in the brain’s axons and nerve endings causes the worst damage in AD by impairing communication between nerve cells (or neurons) in the brain. Researchers around the world have worked intensely to find ways to block the formation of amyloid beta by preventing cleavage by beta secretase and gamma secretase. However, these approaches have been hampered by safety issues.
