What makes some ads more shareable than others?

In one of the more memorable commercials of Super Bowl 2020, rapper Lil Nas X and actor Sam Elliott face off in a dance duel for Cool Ranch Doritos. The cost was arguably worthwhile, considering the millions of times the spot was viewed and shared across social media platforms for free.

Role of WOX1 in compound leaf development revealed

Plant-specific WOX family transcription factors play important roles ranging from embryogenesis to lateral organ development. The WOX1 transcription factors, which belong to the modern clade of the WOX family, are known to regulate outgrowth of the leaf blade specifically in the mediolateral axis; however, the role of WOX1 in compound leaf development remains unknown.

SPIRou carries out first ever measurement of a very young exoplanet's density

A research team led by scientists from IRAP (CNRS/CNES/Université Toulouse III—Paul Sabatier) and IPAG (CNRS/UGA) has for the first time measured the internal density of a very young exoplanet orbiting a newly formed, extremely active star. Despite the 'noise' generated by the star's activity, they successfully achieved this using the Canada-France-Hawaii Telescope (CFHT)'s planet hunting instrument SPIRou. The findings are published in MNRAS on 2 February 2021.

Quantum systems learn joint computing

Today's quantum computers contain up to several dozen memory and processing units, the so-called qubits. Severin Daiss, Stefan Langenfeld, and colleagues from the Max Planck Institute of Quantum Optics in Garching have successfully interconnected two such qubits located in different labs to a distributed quantum computer by linking the qubits with a 60-meter-long optical fiber. Over such a distance they realized a quantum-logic gate—the basic building block of a quantum computer. It makes the system the worldwide first prototype of a distributed quantum computer.

CRISPR editing of mitochondria: Promising new biotech?

Although the CRISPR/Cas9 system has seen widespread application in editing the nuclear genome, using it to edit the mitochondrial genome has been problematic. The main hurdles have been a lack of suitable editing sites in the small mtDNA, and the traditional difficulty of importing the guide RNA into the mitochondrial matrix where nucleoids can be accessed.

Can a miniscule worm hold the secret to genetically reversing brain damage?

A team of Hebrew University researchers have successfully used genetic engineering as a first step to what one day may allow scientists to genetically repair damaged brain circuits. The process, which was performed in tiny translucent C. elegans worms, saw the introduction of synthetically engineered connections (or synapses), as a means for bypassing missing connections between neurons in an impaired brain.

Scientists reveal synergistic effects in dual single-atom catalyst

Single-atom catalysts (SACs) are applied in heterogeneous catalysis. Instead of one type of single atom, dual single-atom catalysts (DSACs) deliver superior catalytic performance than SACs due to cooperation between the dual metal-atoms.

Crystalline polymers for the rapid detection and efficient degradation of ozone

Ozone is a problematic air pollutant that causes serious health problems. A newly developed material not only quickly and selectively indicates the presence of ozone, but also simultaneously renders the gas harmless. As reported by Chinese researchers in Angewandte Chemie, the porous "two-in-one systems" also function reliably in very humid air.

Neanderthal gut microbiota and the bacteria helping our health

Neanderthals' gut microbiota included beneficial microorganisms that are also found in the modern human microbiome. An international research group led by the University of Bologna achieved this result by extracting and analyzing ancient DNA from 50,000-year-old fecal sediments sampled at the archaeological site of El Salt, near Alicante (Spain).

Bimeronium: A new member of the topological spin textures family

Topological spin textures in magnetic systems are intriguing objects that exhibit exotic physics and have potential applications in information storage and processing. The most fundamental and exemplary topological spin texture is called the skyrmion, which is a nanoscale circular domain wall carrying a nonzero integer topological charge. The skyrmion texture in magnetic materials was theoretically predicted in the late 1980s, and it was experimentally observed in chiral magnets a decade ago. Since the first observation of magnetic skyrmions, the skyrmion community has focused on a series of topological spin textures evolved from the skyrmion, such as the skyrmionium and bimeron.

Mapping hotspots of undersized fish and crustaceans may aid sustainable fishing practices

A new study in Frontiers in Marine Science provides a first-of-its-kind evaluation of which regions of southern European seas are in the most need of fishing restrictions. These areas have persistently shown high numbers of undersized fish and crustaceans, which are typically discarded because they are below the allowable size limit for collection. These findings may offer a strategy for prioritizing conservation efforts and ensuring more sustainable fishery management in the future.
