Often seen, never studied: First characterization of a key postsynaptic protein
2024-03-07
A protein that appears in postsynaptic protein agglomerations has been found to be crucial to their formation. The Kobe University discovery identifies a new key player for synaptic function and sheds first light on its hitherto uncharacterized cellular role and evolution.
What happens at the synapse, the connection between two neurons, is a key factor in brain function. The transmission of the signal from the presynaptic to the postsynaptic neuron is mediated by proteins and their imbalance can lead to neuropsychiatric ...
How does a virus hijack insect sperm to control disease vectors and pests?
2024-03-07
UNIVERSITY PARK, Pa. — A widespread bacteria called Wolbachia and a virus that it carries can cause sterility in male insects by hijacking their sperm, preventing them from fertilizing eggs of females that do not have the same combination of bacteria and virus. A new study led by microbiome researchers at Penn State has uncovered how this microbial combination manipulates sperm, which could lead to refined techniques to control populations of agricultural pests and insects that carry diseases like Zika and dengue to humans.
The study is published in the March 8 issue of the journal Science.
“Wolbachia is the most widespread bacteria in ...
How the brain coordinates speaking and breathing
2024-03-07
CAMBRIDGE, MA -- MIT researchers have discovered a brain circuit that drives vocalization and ensures that you talk only when you breathe out, and stop talking when you breathe in.
The newly discovered circuit controls two actions that are required for vocalization: narrowing of the larynx and exhaling air from the lungs. The researchers also found that this vocalization circuit is under the command of a brainstem region that regulates the breathing rhythm, which ensures that breathing remains dominant over speech.
“When you need to breathe in, you have to stop vocalization. We found that the neurons that control vocalization ...
Shape-shifting ultrasound stickers detect post-surgical complications
2024-03-07
EVANSTON, Ill. — Researchers led by Northwestern University and Washington University School of Medicine in St. Louis have developed a new, first-of-its-kind sticker that enables clinicians to monitor the health of patients’ organs and deep tissues with a simple ultrasound device.
When attached to an organ, the soft, tiny sticker changes in shape in response to the body’s changing pH levels, which can serve as an early warning sign for post-surgery complications such as anastomotic leaks. Clinicians then ...
The Malaria parasite generates genetic diversity using an evolutionary ‘copy-paste’ tactic
2024-03-07
By dissecting the genetic diversity of the most deadly human malaria parasite – Plasmodium falciparum – researchers at EMBL’s European Bioinformatics Institute (EMBL-EBI) have identified a mechanism of ‘copy-paste’ genetics that increases the genetic diversity of the parasite at accelerated time scales. This helps solve a long-standing mystery regarding why the parasite displays hotspots of genetic diversity in an otherwise unremarkable genetic landscape.
Malaria is most commonly transmitted through the bites of female Anopheles mosquitoes infected with P. falciparum. The latest world malaria report ...
Loss of nature costs more than previously estimated
2024-03-07
Researchers propose that governments apply a new method for calculating the benefits that arise from conserving biodiversity and nature for future generations.
The method can be used by governments in cost-benefit analyses for public infrastructure projects, in which the loss of animal and plant species and ‘ecosystem services’ – such as filtering air or water, pollinating crops or the recreational value of a space – are converted into a current monetary value.
This process is designed to make biodiversity loss and the benefits of nature conservation more visible in political decision-making.
However, the international research team ...
Lack of functional eyes does not affect biological clock in zebrafish
2024-03-07
Functional eyes are not required for a working circadian clock in zebrafish, as a research team1 including CNRS scientists has now shown.
Though it is understood that the eye plays a key role in mammalian adaptation to day-night cycles, the circadian clock is most often studied in nocturnal vertebrates such as mice. The zebrafish, in contrast, is a diurnal vertebrate. Through observation of various zebrafish larvae lacking functional eyes,2 the team of scientists has demonstrated that the latter are not needed to establish circadian rhythms that remain synchronized with light-dark ...
The who's who of bacteria: A reliable way to define species and strains
2024-03-07
What’s in a name? A lot, actually.
For the scientific community, names and labels help organize the world’s organisms so they can be identified, studied, and regulated. But for bacteria, there has never been a reliable method to cohesively organize them into species and strains. It’s a problem, because bacteria are one of the most prevalent life forms, making up roughly 75% of all living species on Earth.
An international research team sought to overcome this challenge, which has long plagued scientists who study bacteria. Kostas Konstantinidis, Richard ...

NJIT professor trains college counselors to help fight antisemitism
2024-03-07
As data from the Anti-Defamation League shows antisemitism growing on college campuses in recent years and spiking after the Hamas-Israel conflict, a New Jersey Institute of Technology researcher is doing her part to combat the trend by developing a training model that will help prepare mental health professionals who work with Jewish students.
Modern students are hearing people chant slogans without understanding the intentions behind the words, or finding swastikas and other anti-Jewish graffiti on their campuses, but they are not encountering suitably trained counselors and psychologists who understand their ...
For new moms who rent, housing hardship and mental health are linked
2024-03-07
Becoming a parent comes with lots of bills. For new mothers, being able to afford the rent may help stave off postpartum depression.
“Housing unaffordability has serious implications for mental health,” said Katherine Marcal, an assistant professor at the Rutgers School of Social Work and author of a study published in the journal Psychiatry Research. “For mothers who rent their homes, the ability to make monthly payments appears to have a correlation to well-being.”

Plant science: Tracing the spread of cacao domestication
2024-03-07
The cacao tree (Theobroma cacao), whose beans (cocoa) are used to make products including chocolate, liquor and cocoa butter, may have spread from the Amazon basin to the other regions of South and Central America at least 5,000 years ago via trade routes, suggests a paper published in Scientific Reports. These findings, based on residues in ancient vessels, reveal how different strains of cacao tree were bred and suggest that cacao products were more widely used among ancient South and Central American cultures than previously thought.
The modern cacao tree — whose scientific ...

National trends in sales and price for commercial tobacco and nicotine products
2024-03-07
About The Study: Although cigarettes remained the dominant product sold during the study period (2018-2022), their market share decreased, leading to a more diverse marketplace at a range of price points. The fastest growing and only price-stable products were modern oral nicotine (e.g., nicotine pouches). The most expensive products were electronic nicotine delivery systems, yet prices decreased in 2019, coinciding with the emergence of cheap, flavored disposable vapes. Cigars, which are largely flavored, remained the cheapest product, driven by low cost and small pack sizes, which is concerning given that flavored ...

Too few caregivers and too many patients – a bad combination for elderly in rural areas
2024-03-07
Ageing baby boomers are swelling the ranks of elderly across the Western world, with Norway no exception.
We know Norway's elderly population will increase, and it's likely there will be far fewer healthcare professionals to take care of them. The last 20 years has seen the population of Norwegians over the age of 80 increase by 40,000; the percentage of people aged 67-79 has grown by 37.9 per cent over the last 10 years.
Over the next 20 years, there will be 250,000 more Norwegians over the age of 80.
The ageing crisis has been predicted for ...
Earth’s earliest forest revealed in Somerset fossils
2024-03-07
The oldest fossilised forest known on Earth – dating from 390 million years ago – has been found in the high sandstone cliffs along the Devon and Somerset coast of South West England.
The fossils, discovered and identified by researchers from the Universities of Cambridge and Cardiff, are the oldest fossilised trees ever found in Britain, and the oldest known fossil forest on Earth. This fossil forest is roughly four million years older than the previous record holder, which was found in New York State.
