New study shows meaningful social interactions boost well-being, but context matters
2024-06-28
Engaging in meaningful social interactions with peers is associated with lower loneliness and greater affective well-being, new research finds. Researchers followed three cohorts of university students over three years, collecting data on their social interactions and momentary well-being.
Prior research has focused on the impacts of social interactions and the contexts in which interactions occur, such as places and activities. However, the new research specifically examines the impact of meaningful interactions on well-being. “Our research indicates that engaging in meaningful social interactions have net positive outcomes for affective well-being, stress, and loneliness,” ...

Study reveals why AI models that analyze medical images can be biased
2024-06-28
Artificial intelligence models often play a role in medical diagnoses, especially when it comes to analyzing images such as X-rays. However, studies have found that these models don’t always perform well across all demographic groups, usually faring worse on women and people of color.
These models have also been shown to develop some surprising abilities. In 2022, MIT researchers reported that AI models can make accurate predictions about a patient’s race from their chest X-rays — something that the most skilled radiologists can’t do.
That research team has now found that the models that are most accurate at making demographic predictions ...

New predictors of metastasis in patients with early-stage pancreatic cancer
2024-06-28
Researchers at Weill Cornell Medicine with an international team have used liver biopsies to identify cellular and molecular markers that can potentially be used to predict whether and when pancreatic cancer will spread to an individual’s liver or elsewhere, such as the lung.
The study, published on June 28 in Nature Medicine, proposes that information from a liver biopsy—a small tissue sample collected for lab analysis—when pancreatic cancer is diagnosed may help guide doctors in personalizing treatment, such as liver-directed immunotherapies, before cancer cells have the chance to metastasize.
Only 10 percent of people with pancreatic ...
Climate change to shift tropical rains northward
2024-06-28
A study led by a UC Riverside atmospheric scientist predicts that unchecked carbon emissions will force tropical rains to shift northward in the coming decades, which would profoundly impact agriculture and economies near the Earth's equator.
The northward rain shift would be caused by complex changes in the atmosphere spurred by carbon emissions that influence the formation of the intertropical convergence zones. Those zones are essentially atmospheric engines that drive about a third of the world’s precipitation, Liu and his co-authors report in a paper published Friday, June 28, in the journal Nature Climate Change.
Tropical ...

The new research, led by scientists at Imperial College London and ETH Zurich working as part of NASA's InSight mission, has shed light on how often ‘marsquakes’ caused by meteorite impacts occur on Mars.
The researchers found that Mars experiences around 280 to 360 meteorite impacts every year that produce craters larger than eight metres in diameter and shake the red planet’s ...
Air pollution exposure during childhood linked directly to adult bronchitis symptoms in new research
2024-06-28
A new study brings fresh revelations about the connection between early-life exposure to air pollution and lung health later in life. A research team led by the Keck School of Medicine of USC has shown that exposure to air pollution during childhood is directly associated with bronchitis symptoms as an adult.
To date, many investigations in the field have established intuitive links that are less direct than that: Air pollution exposure while young is consistently associated with lung problems during childhood — and childhood lung problems are consistently associated with lung issues as an adult.
The current study, published in the American Journal of Respiratory ...
Kids given ‘digital pacifiers’ to calm tantrums fail to learn how to regulate emotions, study finds
2024-06-28
Children learn much about self-regulation – that is affective, mental, and behavioral responses to certain situations – during their first few years of life. Some of these behaviors are about children’s ability to choose a deliberate response over an automatic one. This is known as effortful control, which is learned from the environment, first and foremost through children’s relationship with their parents.
In recent years, giving children digital devices to control their responses to emotions, especially if they’re negative, has ...
No evidence that England’s new ‘biodiversity boost’ planning policy will help birds or butterflies
2024-06-28
A new legal requirement for developers to demonstrate a biodiversity boost in planning applications could make a more meaningful impact on nature recovery if improvements are made to the way nature’s value is calculated, say researchers at the University of Cambridge.
From 2024, the UK’s Environment Act requires planning applications to demonstrate an overall biodiversity net gain of at least 10% as calculated using a new statutory biodiversity metric.
The researchers trialled the metric by using it to calculate the biodiversity value of 24 sites across England. These sites have all been monitored over the long-term, allowing the team to compare biodiversity ...

Junior rank, male sex, younger age strongly linked to ‘harmful gambling’ among UK military
2024-06-28
Several indicative factors, including junior rank, male sex, and younger age, are strongly linked to ‘harmful gambling’ among serving UK military personnel, finds an analysis of survey responses, published online in the journal BMJ Military Health.
Harmful gambling refers to the toll taken on finances, health, personal relationships, and work: nearly 1 in 4 respondents reported one or other of these effects over the past year.
The findings prompt the researchers to call for the prioritisation of better, earlier, and targeted support to stave off the harmful consequences of ...
Poorer teen mental ability linked to as much as tripling in stroke risk before age of 50
2024-06-28
A lower level of mental ability during the teenage years may be linked to as much as a tripling in the risk of having a stroke before the age of 50, finds research published online in the Journal of Epidemiology & Community Health.
The observed associations held true even after factoring in current diabetes and limiting the age of a first stroke up to 40, prompting the researchers to suggest that more comprehensive assessments beyond traditional stroke risk factors are now needed to stave off disability and death.
Recent evidence suggests that cases of stroke ...
Adults conceived by donors left behind by fertility industry
2024-06-28
Children conceived by using egg or sperm donors have the same well-being outcomes as non-donor conceived people.
However, they are more likely to have identity difficulties and issues with trust. Secrecy and anonymity about their genetic parentage can have a profound impact on well-being say authors. They warn that children and adults conceived using donor gametes have not been centred in the assisted reproductive industry and more information is needed about adult wellbeing.
The study is published today in the British Journal of Obstetrics and Gynaecology by researchers King’s College London. The study is the first systematic ...

The method, which simplifies the process and enhances its efficiency, is described in an article published in Journal of Food Composition and Analysis.
The aim was to optimize extraction of anthocyanin, a potent antioxidant found in strawberries, blackberries and raspberries as well as jabuticabas, among other sources. It has anti-inflammatory effects and is also a natural ...
Researchers discover how nerve cells in bat brains respond to their environment and social interactions with other bats
2024-06-28
Vienna, Austria: Researchers have found that nerve cells in the hippocampus region of the brain encode complex information on numerous characteristics of other individuals in the same social group.
The work, which is being carried out in bats, is the first to show this in a large, mixed-sex group of wild, social animals, and is important because it sheds light on how the brain operates and generates thinking processes and behaviour.
Professor Nachum Ulanovsky, Head of the Center for Learning, Memory and Cognition at the Weizmann Institute of Science, ...
Simulating blood flow dynamics for improved nanoparticle drug delivery
2024-06-27
Despite gaining a bad rap in mainstream media in recent years, nanoparticles have been successfully used for decades in targeted drug delivery systems. Drug molecules can be encapsulated within biodegradable nanoparticles to be delivered to specific cells or diseased tissues. However, blood flow dynamics can significantly affect the nanoparticle’s ability to bind at the target site and stay adhered long enough for the drug to be released.
Drawing inspiration from civil, mechanical, electrical and chemical engineering, University of Illinois Urbana-Champaign professors Arif Masud and Hyunjoon Kong have developed and tested a new mathematical model to accurately simulate ...
