Virus-like probes could help make rapid COVID-19 testing more accurate, reliable
Nanoengineers at the University of California San Diego have developed new and improved probes, known as positive controls, that could make it easier to validate rapid, point-of-care diagnostic tests for COVID-19 across the globe. The advance could help expand testing to low-resource, underserved areas.

CRISPR tagging improves accuracy of model cells grown from stem cells
CRISPR tags are being used to identify all of the transcription factors necessary to turn a pluripotent stem cell into a suitable adult cell for research, and possible future cell therapies. A paper in Cell Reports documents its use for making adult neuronal cells, but the technique could be applied to any cell type.

How the insect got its wings: Scientists (at last!) tell the tale
How insect wings evolved has puzzled biologists for over a century. Finally, a team from the Marine Biological Laboratory, Woods Hole, has shown that the insect wing evolved from an outgrowth on the crustacean leg that was incorporated into the animal's body wall.

Ultrathin spray-applied MXene antennas are ready for 5G
New antennas so thin that they can be sprayed into place are also robust enough to provide a strong signal at bandwidths that will be used by fifth-generation (5G) mobile devices. Performance results for the antennas, which are made from a new type of two-dimensional material called MXene, were recently reported by researchers at Drexel University and could have rammifications for mobile, wearable and connected "internet of things" technology.

Black bear gut biome surprisingly simple, scientists say
In recent decades, researchers have found that most mammals' guts are surprisingly complex environments - home to a variety of microbial ecosystems that can profoundly affect an animal's well-being. Scientists have now learned that the bear appears to be an exception, with its gut playing host to a microbial population that varies little across the intestinal tract.

Via circuit tracing and behavioral manipulation using optogenetics, a new study shows that a region of the prefrontal cortex connects to the superior colliculus to override the SC's reflexive action when executive control is necessary.

Airplane noise at night can trigger cardiovascular death
For the first time, a study demonstrated that loud night-time noise from airplanes can trigger a cardiovascular death within two hours. Researchers from the Swiss Tropical and Public Health Institute (Swiss TPH) and partners compared mortality data with acute night-time noise exposure around Zurich airport between 2000 and 2015. The results of the study have been published today in the renowned European Heart Journal.

Sun model completely confirmed for the first time
The Borexino experiment research team has succeeded in detecting neutrinos from the sun's second fusion process, the Carbon Nitrogen Oxygen cycle (CNO cycle) for the first time. This means that all of the theoretical predictions on how energy is generated within the sun have now also been experimentally verified. The findings are the result of years of efforts devoted to bringing the background sources in the energy range of the CNO neutrinos under control.

Princeton scientists solve the mystery behind an enigmatic organelle, the pyrenoid
Princeton researchers Shan He, Martin Jonikas, and colleagues have discovered how Rubisco holoenzymes assemble to form the fluid-like matrix of the algal pyrenoid, an organelle that mediates the incorporation of carbon dioxide into sugars. The study detailing the group's findings was published November 23, 2020 in the journal Nature Plants.

Princeton scientists discover a motif that guides assembly of the algal pyrenoid
Princeton University researchers have discovered that assembly of the algal pyrenoid, a structure that mediates the incorporation of carbon dioxide into sugars, is guided by the presence of a particular protein sequence, or motif. The study describing this breakthrough, by researchers Moritz Meyer, Martin Jonikas, and colleagues, appeared November 11, 2020 in the open-access journal Science Advances.

Sniffing your way to the gym
On a near daily basis, the internet spews out numerous tips and tricks for exercise motivation. Now we can add smell to the long and growing list. A research team led by a scientist at the University of California, Riverside, has found olfaction--or smell--may play an important role in motivating mammals to engage in voluntary exercise. Performed in lab mice, the study may open up new areas of research and have relevance for humans.

Offshore submarine freshwater discovery raises hopes for islands worldwide
Twice as much freshwater is stored offshore of Hawai'i Island than previously thought, revealed a University of Hawai'i study with important implications for volcanic islands around the world. An extensive reservoir of freshwater within the submarine southern flank of the Hualālai aquifer was mapped by researchers with Hawai'i EPSCoR 'Ike Wai project, showing a way in which substantial volumes of freshwater are transported from onshore to offshore submarine aquifers along the coast of Hawai'i Island.

In fire-prone West, plants need their pollinators -- and vice versa
A new study grounded in the northern Rockies explores the role of wildfire in the finely tuned dance between plants and their pollinators. Previous studies have looked at how fire affects plants, or how fire affects animals. But what is largely understudied is the question of how fire affects both, and about how linkages within those ecological networks might respond to fire disturbance. The findings are particularly significant in light of recent reports about the rapid and widespread decline of insects globally.

Simple new testing method aims to improve time-release drugs
UC Riverside engineers filled a glass tube bent like a tuning fork, kept vibrating by a circuit at its resonance frequency, with simulated stomach and intestine contents and passed an over-the-counter time-release drug granule through the tube. They observed a brief change in the frequency. When plotted, they could compare the peaks of resonance frequency against the time to learn the buoyant mass of the drug granule at that moment.
