New article provides orientation to using implementation science in policing
2024-10-03
Since the 2020 murder by Minneapolis police of George Floyd brought nationwide calls for change amid concerns that prevailing practices were not grounded in evidence and created harm, policing has been in turmoil. Implementation science (IS) involves integrating effective and evidence-based innovations into routine practice in fields like health care. Yet despite its potential, IS—and specifically, evidence-based policing (EBP)—remain vastly understudied and unused in police settings. In a new article, researchers provide an orientation to these issues ...

In odd galaxy, NASA's Webb finds potential missing link to first stars
2024-10-03
Looking deep into the early universe with NASA’s James Webb Space Telescope, astronomers have found something unprecedented: a galaxy with an odd light signature, which they attribute to its gas outshining its stars. Found approximately one billion years after the big bang, galaxy GS-NDG-9422 (9422) may be a missing-link phase of galactic evolution between the universe’s first stars and familiar, well-established galaxies.
“My first thought in looking at the galaxy’s spectrum was, ‘that’s weird,’ which is ...

What happens in the brain when a person with schizophrenia “hears voices”?
2024-10-03
Auditory hallucinations are likely the result of abnormalities in two brain processes: a “broken” corollary discharge that fails to suppress self-generated sounds, and a “noisy” efference copy that makes the brain hear these sounds more intensely than it should. That is the conclusion of a new study published October 3rd in the open-access journal PLOS Biology by Xing Tian, of New York University Shanghai, China, and colleagues.
Patients with certain mental disorders, including schizophrenia, often hear voices in the absence of sound. Patients may fail to distinguish between their ...
Ant agriculture began 66 million years ago in the aftermath of the asteroid that doomed the dinosaurs
2024-10-03
When humans began farming crops thousands of years ago, agriculture had already been around for millions of years. In fact, several animal lineages have been growing their own food since long before humans evolved as a species.
According to a new study, colonies of ants began farming fungi when an asteroid struck Earth 66 million years ago. This impact caused a global mass extinction but also created ideal conditions for fungi to thrive. Innovative ants began cultivating the fungi, creating an evolutionary partnership that became even more tightly intertwined 27 million years ago and continues to this day.
In a paper published today, Oct. 3, in the journal Science, scientists at the Smithsonian’s ...

The true global impact of species-loss caused by humans is far greater than expected – new study reveals
2024-10-03
The extinction of hundreds of bird species caused by humans over the last 130,000 years has has led to substantial reductions in avian functional diversity – a measure of the range of different roles and functions that birds undertake within the environment –
and resulted in the loss of approximately 3 billion years of unique evolutionary history, according to a new study published today in Science.
Whilst humans have been driving a global erosion of species richness for millennia, the consequences of past extinctions for other dimensions of biodiversity are poorly known. ...
Smartphone-assisted “scavenger hunt” identifies people at risk for dementia
2024-10-03
Researchers from DZNE and Otto von Guericke University Magdeburg have identified individuals with increased risk for dementia using mobility data, recorded during a smartphone-based wayfinding task on the university campus. The findings, reported in the journal PLOS Digital Health, show the potential of smartphone data, collected in conditions close to everyday life, for the early detection and monitoring of Alzheimer’s disease. The study included 72 adults; about a third of them with subjective cognitive decline (SCD), a condition that is a known risk factor for dementia.
Alzheimer’s disease usually develops unnoticed over years and eventually ...
Green subsidies may have hidden costs, experts warn
2024-10-03
Government subsidies for business practices and processes should be approached with caution, even when they seem to be environmentally friendly, writes a group of scientists and economists in this week’s Policy Forum in the journal Science.
They argue that subsidies can alter market pressures, leading to unintended consequences that not only perpetuate harmful subsidies over time but also diminish the overall effectiveness of those intended to promote environmental sustainability.
Therefore, when they must be used, subsidies should have clear end-dates, advise the authors.
“We’ve got this odd juxtaposition of ...
Small brains can accomplish big things, according to new theoretical research
2024-10-03
Neuroscientists had a problem.
For decades, researchers had a theory about how an animal’s brain keeps track of where it is relative to its surroundings without outside cues – like how we know where we are, even with our eyes closed.
According to the theory, which was based on brain recordings from rodents, networks of neurons called ring attractor networks maintain an internal compass that keeps track of where you are in the world. An accurate internal compass was thought to require a large network with many neurons, while a small network with few neurons would cause the compass’s needle to drift, creating errors.
Then researchers discovered an internal compass ...

Decline of mpox antibody responses after modified vaccinia Ankara–Bavarian Nordic vaccination
2024-10-03
About The Study: The modified vaccinia Ankara–Bavarian Nordic (MVA-BN) vaccination generated mpox antibodies that waned by 6 to 12 months. In participants who received 2 doses of MVA-BN vaccine, mpox antibody responses at 12 months were comparable to or lower than peak antibody responses in people receiving 1 dose, which provided limited protection.
Quote from corresponding author Dan H. Barouch, MD, PhD:
“In this observational study, we show that mpox antibody responses decline 6-12 months following Jynneos (MVA-BN) vaccination. Our data suggest that protective immunity may ...
Wider use of convalescent plasma might have saved thousands more lives during pandemic
2024-10-03
A new study led by researchers at Johns Hopkins Bloomberg School of Public Health estimates that thousands of lives could have been saved during the first year of the COVID-19 pandemic if convalescent plasma had been used more broadly, particularly in outpatients at high risk for severe disease and in hospitalized patients during their first few days of admission.
Convalescent plasma from patients who had recovered from COVID was used starting in the early months of the pandemic at the urging of a group of physicians who cited the blood ...
Strong coupling between Andreev qubits mediated by a microwave resonator
2024-10-03
Quantum communication and quantum computing operate based on quantum bits (qubits) as the smallest unit of information — related to bits in a classical computer. Of the many different approaches currently being investigated around the world, one promising option is to use Andreev pair qubits.
These qubits are formed at interfaces between a metal and a superconductor in a process known as Andreev reflection. Here, an electron from the metal enters the superconductor, where it becomes part of an electron pair (a Cooper pair) — while a hole, ...

Stem cell transplants close macular holes in monkeys
2024-10-03
Human stem cell transplants successfully repaired macular holes in a monkey model, researchers report October 3rd in the journal Stem Cell Reports. After transplantation, the macular holes were closed by continuous filling of the space with retinal tissue.
“We confirmed for the first time in a non-human primate model that embryonic stem-derived retinal organoid sheet transplantation facilitates the closure of macular holes,” says senior study author Michiko Mandai of the Kobe City Eye Hospital. “Our results suggest that this method could become a practical, safe, and effective ...
Our brains divide the day into chapters. New psychology research offers details on how.
2024-10-03
The moment a person steps off the street and into a restaurant—to take just one example—the brain mentally starts a new “chapter” of the day, a change that causes a big shift in brain activity. Shifts like this happen all day long, as people encounter new environments, like going out for lunch, attending their kid’s soccer game, or settling in for a night of watching TV.
But what determines how the brain divides the day into individual events that we can understand and remember separately? That’s what a new paper in the journal Current Biology aimed to find ...
Fear of cancer recurrence in adult survivors of childhood cancer
2024-10-03
About The Study: Decades following treatment, one-third of childhood cancer survivors in this study reported elevated fear their cancer will recur or a subsequent malignant neoplasm will develop. Findings suggest that fear of cancer recurrence should be routinely screened, and clinically significant symptoms intervened upon as a part of survivorship care.

AI algorithm for subclinical breast cancer detection
2024-10-03
About The Study: In this retrospective cohort study of women undergoing screening mammography, mean absolute artificial intelligence (AI) scores were higher for breasts developing vs not developing cancer 4 to 6 years before their eventual detection. These findings suggest that commercial AI algorithms developed for breast cancer detection may identify women at high risk of a future breast cancer, offering a pathway for personalized screening approaches that can lead to earlier cancer diagnosis.

UTEP study: Zooplankton go “Eew!” to cleaning feces contaminated water
2024-10-03
EL PASO, Texas (Oct. 3, 2024) – Scientists at The University of Texas at El Paso and Stanford University were recently surprised to find that the natural community of zooplankton — tiny, aquatic animals known to graze on bacteria — present in freshwater and saltwater do not clean water that is contaminated with fecal microorganisms.
The research, published today in the biology journal mSphere, reveals important insights about the limitations of zooplankton in treating bodies of water that have been contaminated with fecal organisms, the team said. A 2017 U.S. water quality inventory ...
