Scientists take next big step in understanding genetics of schizophrenia
2023-09-15
Genetically speaking, we are individuals different from each other because of slight variations in our DNA sequences – so-called genetic variants – some of which have dramatic effects we can see and comprehend, from the color of our eyes to our risk for developing schizophrenia – a debilitating psychiatric condition affecting many millions worldwide. For several years, scientists have studied the entire genomes of thousands of people – called genome-wide association studies, or GWAS – to find approximately 5,000 genetic variants associated with schizophrenia.

UMass Amherst neuroscientist aims to advance knowledge of human brain development by mapping the sea slug brain
2023-09-15
A University of Massachusetts Amherst neuroscientist has been awarded a $3.1 million grant from the National Institute of Neurological Disease and Stroke to advance knowledge on human brain development by using an unusual subject: the brain of the sea slug.
This tiny invertebrate is an ideal candidate to study for brain development because it adds a countable number of neurons to its brain – the number increases more than 40-fold in less than eight weeks to a total of about 10,000 neurons – while the animal grows and performs behaviors, ...
No pollen, no seeds
2023-09-15
North Carolina State University researchers have successfully transferred an important gene from one compartment of a plant cell to another to produce tobacco plants that lack pollen and viable seeds, while otherwise growing normally. Their findings could lead to better ways of producing hybrid seeds to maximize crop productivity, or to introduce seedlessness in fruit species lacking the often-desired trait, such as raspberries, blackberries or muscadine grapes.
The researchers began the work in the energy-producing portion of a cell, the mitochondria. In plants, aberrations within the mitochondrial genome can be associated with ...
Hydroelectric power plants in Brazil threaten turtles that depend on rapids, study warns
2023-09-15
A research project supported by FAPESP shows that the construction of new hydroelectric power plants in Brazil’s South region could have an impact on more than 30% of the habitat of Phrynops williamsi, the Williams’ side-necked turtle. The species occurs only in areas of Atlantic Rainforest and Pampa (the grassland biome adjacent to Brazil’s border with Uruguay and Argentina), and is classed as “Vulnerable” (facing a high risk of extinction) by the International Union for Conservation of Nature (IUCN).
An article on the study is published in the Journal of Applied Ecology by ...

Study: No evidence that YouTube promoted anti-vaccine content during COVID-19 pandemic
2023-09-15
CHAMPAIGN, Ill. — New research led by data science experts at the University of Illinois Urbana-Champaign and United Nations Global Pulse found that there is no strong evidence that YouTube promoted anti-vaccine sentiment during the COVID-19 pandemic.
The study, published in the Journal of Medical Internet Research, performed an algorithmic audit to examine if YouTube’s recommendation system acted as a “rabbit hole,” leading users searching for vaccine-related videos to anti-vaccine content.
For the study, the researchers asked World Health Organization-trained participants and workers from Amazon Mechanical Turk to intentionally ...
New ways to predict outcomes of pregnancies with fetal growth problems
2023-09-15
A team of scientists, led by researchers at UCL, have developed new methods to predict outcomes for pregnancies where there are issues with poor growth of the baby inside the womb.
The research, published in the Journal of Clinical Investigation, involved 142 women from the EVERREST Prospective Study* who had severe early-onset fetal growth restriction (FGR) – meaning their babies were very small on ultrasound scans early in the second half of pregnancy (between 20 and 27 weeks).
Fetal growth restriction affects approximately ...

New double z-scheme photocatalyst for selective removal of sulfamethoxazole in water
2023-09-15
In a new study published on 26 July 2023, in the journal Environmental Science and Ecotechnology, researchers from Harbin Institute of Technology, have developed a novel double Z-scheme photocatalyst, called the molecularly imprinted TiO2@Fe2O3@g-C3N4 (MFTC) composite, that selectively removes SMX from water.
Traditional photocatalytic methods have faced challenges with selectivity, often causing the indiscriminate degradation of organic pollutants and coexisting contaminants at high concentrations. However, the MFTC composite was purposefully designed to overcome this limitation by incorporating molecularly imprinted sites on its surface. These specialized ...
Cost of public health insurance for US-born and immigrant adults
2023-09-15
About The Study: The findings of this study of 44,000 low-income, working-age adults suggest that the direct cost of providing public health insurance to immigrants is less than that for the U.S. born, and immigrants’ health care utilization, upon coverage, remains comparatively modest, thus refuting the notion that providing insurance to immigrants imposes a heavy fiscal burden.
Authors: Felix M. Muchomba, Ph.D., of the State University of New Jersey in New Brunswick, is the corresponding author.

Newly discovered trigger of Parkinson’s upends common beliefs
2023-09-15
· How two sisters’ misfortune led to discovery
· Findings open a new avenue for therapies
· Drugs need to target neuron synapses before neurons degenerate
CHICAGO --- A new Northwestern Medicine study challenges a common belief in what triggers Parkinson’s disease.
Degeneration of dopaminergic neurons is widely accepted as the first event that leads to Parkinson’s. But the new study suggests that a dysfunction in the neuron’s synapses — the tiny gap across which a neuron can send an impulse to another neuron — leads to deficits in dopamine and precedes the neurodegeneration.
Parkinson’s disease ...
The first local case of mpox caused by an imported case in the Chinese mainland
2023-09-15
https://doi.org/10.1016/j.bsheal.2023.07.003
Monkeypox (mpox) is a zoonotic disease caused by the mpox virus (MPXV) that has been primarily limited to Central and West African nations since its discovery. The recent spread of the West African lineage of MPXV in historically unaffected countries has raised concerns for global public health. Despite a significant decrease in global mpox cases, there is still a risk of a global resurgence. This study reports the first local case of mpox caused by an imported case in the Chinese mainland. Polymerase chain reaction (PCR) diagnosed the two ...

The data consists of a questionnaire that was distributed to all ...
Engineers join forces for eco-efficient online shopping
2023-09-15
Home-delivery services perpetually compete for the consumer’s attention not only through advertisements but also through methods that reduce basket decision time or make new suggestions. Current research on the topic focuses on optimizing delivery schedules and minimizing costs. However, neither the insufficiency of home delivery options for some cities nor the bigger problem of high carbon emissions due to the abundance of it, are resolved.
A new study conducted by Koç University Industrial Engineering Department professor Barış Yıldız takes a fresh perspective ...
Receipt of BNT162b2 vaccine and COVID-19 ambulatory visits in young US children
2023-09-15
About The Study: Receiving at least two doses of wild-type BNT162b2 vaccine (Pfizer) was associated with a reduced risk of COVID-19 emergency department or urgent care and outpatient visits in children younger than five years. The risk of SARS-CoV-2 encounters appeared lower for those with two versus three doses of BNT162b2, albeit with wide CIs, which is likely due to more immune-evasive Omicron sublineages (e.g., BQ.1-related and XBB-related strains) becoming dominant by the time young children received their third dose and longer median time since dose three compared with dose two.
Authors: Sara Y. Tartof, Ph.D., M.P.H., of ...
New parent? Night shift? New analysis suggests ideal nap strategy to survive all-nighters
2023-09-15
New analysis of pilot studies on night shift naps conducted from 2012 to 2018 revealed the ideal snoozing strategy that might help counteract drowsiness and fatigue during a 16-hour overnight duty. The findings can also benefit new parents.
Reanalysis of data showed that when staying up all night, scheduling two nap sessions — a 90-minute one followed by a quick 30-minute shut-eye later — is the optimal choice over a single 120-minute snooze in putting off drowsiness and fatigue. The study was published in the journal Scientific Reports.
“A 90-minute nap to maintain long-term performance and a ...
Anesthesiology researcher pipeline lags behind other specialties
2023-09-15
CHICAGO — Anesthesiology researchers are responsible for some of medicine’s most significant advances, from the Apgar score that tests a newborn’s health to cardiopulmonary resuscitation (CPR). But the number of medical residents in the anesthesiology physician-scientist (researcher) pipeline trails other specialties, particularly among women, according to findings of the Anesthesia Research Council (ARC), published in the journal Anesthesia & Analgesia.
