Scientists reveal structures of neurotransmitter transporter
The many faces of monoamine transporters There are two types of VMAT: VMAT1 and VMAT2. VMAT1 is more specialized, found only in neuroendocrine cells, whereas VMAT2 is found throughout the neuronal system and has significant clinical relevance. “We knew that VMAT2 is physiologically very important,” Lee said. “This transporter is a target for pharmacologically relevant…

Rock from the impact that formed the moon may linger in Earth’s mantle
About 4.5 billion years ago, a Mars-sized object smashed into the young Earth, spraying debris that coalesced to form the moon, many scientists think. Some remnants of that object, called Theia, exist today as large amounts of dense material sitting atop Earth’s core, researchers propose November 1 in Nature. In recent years, geophysicists have discovered…

UChicago chemists make breakthrough in drug discovery chemistry
For years, if you asked the people working to create new pharmaceutical drugs what they wished for, at the top of their lists would be a way to easily replace a carbon atom with a nitrogen atom in a molecule. But two studies from chemists at the University of Chicago, published in Science and Nature,…

How and Why Do Violent Tornadoes Form?
A tornado churns up dust at dusk near Traer, Iowa. Brad Goddard / NOAA One muggy day in July 1986, a news helicopter was recording footage of a festival in Minneapolis when the pilot and photographer glimpsed a tornado over nearby Brooklyn Park. They moved toward it, filming the powerful twister for 25 minutes, mesmerizing…

Alexandra’s legacy: Family sets up foundation to help kids learn about science, nature
When Jan Schmitt’s sister set up a GoFundMe to cover burial expenses for her oldest child, her husband Douglas objected, saying paying for her funeral was their burden to bear as parents. Schmitt told him she’d tell her sister to take it down, but didn’t immediately contact her. The next day, Douglas said he knew…

Husker team partnering with communities to enhance biodiversity
Students who live in rural and tribal communities are surrounded by stunning examples of biodiversity: Grasses, prairies, flowers and wildlife feature more prominently in these youths’ lives compared to many of their peers in urban areas. But systemic factors like geographic isolation, higher rates of poverty and limited educational resources sometimes minimize these students’ opportunities to…

Author Correction: Like-minded sources on Facebook are prevalent but not polarizing
Correction to: Nature https://doi.org/10.1038/s41586-023-06297-w Published online 27 July 2023 In the version of this article initially published, the variable described in Supplementary Table 36 as measuring Facebook “strikes” for violations of content policies against “Coordinated Inauthentic Behavior” (CIB) is inaccurate and does not reflect enforcement of the actual CIB policy, which is not a content-level…

Ultra-sensitive pressure sensing capabilities of defective one-dimensional photonic crystal
Abstract Present research work deals with the extremely sensitive pressure-sensing capabilities of defective one-dimensional photonic crystal structure (GaP/SiO2)N/Al2O3/(GaP/SiO2)N. The proposed structure is realized by putting a defective layer of material Al2O3 in the middle of a structure consisting of alternating layers of GaP and SiO2. The transfer matrix method has been employed to examine the…
