One in three Americans had COVID-19 by the end of 2020, study estimates
A new study estimates that 103 million Americans, or 31 percent of the U.S. population, had been infected with SARS-CoV-2 by the end of 2020. Researchers modeled the spread of the coronavirus, finding that fewer than one-quarter of infections (22 percent) were accounted for in cases confirmed through public health reports based on testing.

In a first, scientists capture a 'quantum tug' between neighboring water molecules
Water is the most abundant yet least understood liquid in nature. It exhibits many strange behaviors that scientists still struggle to explain.

This is why ice floats to the top of a drinking glass and lakes freeze from the surface down, allowing marine life to survive col

Now, researchers have developed tiny 'nanojars' that split bicarbonate into carbonate and capture it, as well as certain toxic anions, so

The world's largest collection of malformed brains
These cross-sections of a human brain were used for teaching. The collection had been neglected for decades when photographer Adam Voorhes first visited, in 2011. These images are taken from a book he published about the brains, coauthored with Alex Hannaford. ADAM VOORHES & ROBIN FINLAY The University of Texas has one of the world's largest collections of preserved abnormal human brains. The 100

Understanding the mind
Inside the three-pound lumps of mostly fat and water inside our heads we can, in a very real sense, find the root of everything we know and ever will know. Sure, the universe gave rise to our brains. But what good is the cosmos without brains and, more specifically, minds? Without them, there'd be no understanding, no appreciation, no probing of great mysteries. Which is what this issue is all ab

Is everything in the world a little bit conscious?
Panpsychism is the belief that consciousness is found throughout the universe—not only in people and animals, but also in trees, plants, and bacteria. Panpsychists hold that some aspect of mind is present even in elementary particles. The idea that consciousness is widespread is attractive to many for intellectual and, perhaps, also emotional reasons. But can it be empirically tested? Surprisingl

How big science failed to unlock the mysteries of the human brain
In September 2011, a group of neuroscientists and nanoscientists gathered at a picturesque estate in the English countryside for a symposium meant to bring their two fields together. At the meeting, Columbia University neurobiologist Rafael Yuste and Harvard geneticist George Church made a not-so-modest proposal: to map the activity of the entire human brain at the level of individual neurons and

Our brains exist in a state of "controlled hallucination"
When you and I look at the same object we assume that we'll both see the same color. Whatever our identities or ideologies, we believe our realities meet at the most basic level of perception. But in 2015, a viral internet phenomenon tore this assumption asunder. The incident was known simply as "The Dress." For the uninitiated: a photograph of a dress appeared on the internet, and people disagre

"I understand what joy is now": An MDMA trial participant tells his story
Nathan McGee was only four years old when he experienced the trauma that would eventually lead him to MDMA therapy almost four decades later. It's still too painful to go into the details. In the intervening years, he played what he calls "diagnosis bingo." Doctors variously told Nathan he had attention deficit hyperactivity disorder, anxiety, depression, and dyslexia. In 2019 he was diagnosed wi

Five poems about the mind
DREAM VENDING MACHINE I feed it coins and watch the spring coil back, the clunk of a vacuum-packed, foil-wrapped dream dropping into the tray. It dispenses all kinds of dreams—bad dreams, good dreams, short nightmares to stave off worse ones, recurring dreams with a teacake marshmallow center. Hardboiled caramel dreams to tuck in your cheek, a bag of orange dreams with Spanish subtitles. One neon

Weather, ocean currents key to fish spawning in Micronesia
Larval fish are spawned in a given location and may be recruited into their next life stage—larger, older fish—in the same place or a distant location. The recruitment of rabbitfish in Guam and groupers in Palau has historically been unpredictable. A published study, co-authored by a University of Hawaiʻi at Mānoa School of Ocean and Earth Science and Technology (SOEST) research professor, found t

Measuring the sound velocity of Majorite under mantle transition zone conditions
Researchers at Ehime University have reported the sound velocity of MgSiO3 Majorite garnet up to the pressure of 18 gigapascals and temperature up to 2,000 Kelvins. Their results lead to understanding of the mineral composition of the Earth's mantle transition zone (MTZ), which has not been fully elucidated yet. This study suggests that a mechanical mixture of slab and mantle rocks, rather than eq

A hybrid molecular peapod of sp2- and sp3-nanocarbons enabling ultrafast terahertz rotations
Nature Communications, Published online: 25 August 2021; doi:10.1038/s41467-021-25358-0 Mechanical motions in hybrid sp2/sp3 -hybrid nanocarbon peapods might lead to promising materials applications, but have been insufficiently explored. Here the authors demonstrate that a diamondoid molecule trapped inside a carbonaceous cylinder undergoes solid-state rotations at terahertz frequencies.

The retinal ipRGC-preoptic circuit mediates the acute effect of light on sleep
Nature Communications, Published online: 25 August 2021; doi:10.1038/s41467-021-25378-w The preoptic area (POA) is critical for sleep regulation but its role in acute, non-circadian, light effects on sleep are unclear. The authors show that intrinsically photosensitive retinal ganglion cells provide substantial input into the POA and through these modulate the amount of non-rapid eye movement (NR

Opposing roles for striatonigral and striatopallidal neurons in dorsolateral striatum in consolidating new instrumental actions

The authors show that D1 receptor-expressing medium spiny neurons (MSNs) in the anterior dorsolateral striatum encode newly learned instrumental actions whereas D2 MSNs promote the

Nature Communications, Published online: 25 August 2021; doi:10.1038/s41467-021-25361-5 Here, Kim et al. apply various sequencing techniques (RPF-seq, QTI-seq, mRNA-seq, sRNA-seq) to unravel the high-resolution, longitudinal translatome and transcriptome of SARS-CoV-2. They identify a translation initiation site in the leader sequence of all genomic and subgenomic RNAs and show its relevance for

Global spread of Salmonella Enteritidis via centralized sourcing and international trade of poultry breeding stocks
Nature Communications, Published online: 25 August 2021; doi:10.1038/s41467-021-25319-7 Salmonella enterica serotype Enteritidis is a pathogen of poultry that can cause outbreaks in humans. Here the authors use genomic and trade data to investigate a pandemic in the 1980s, finding evidence that international trade of breeding stocks led to global spread of the pathogen.

'Nanojars' capture dissolved carbon dioxide, toxic ions from water
Carbon dioxide from the atmosphere can dissolve in oceans, lakes and ponds, forming bicarbonate ions and other compounds that change water chemistry, with possible harmful effects on aquatic organisms. In addition, bicarbonate can reenter the atmosphere as carbon dioxide later, contributing to climate change. Now, researchers have developed tiny "nanojars," much smaller than the width of a human h
