Bias in the collection of data on which Artificial Intelligence (AI) computer programmes depend can limit the usefulness of this rapidly growing tool for climate scientists predicting future scenarios and guiding global action, according to a new paper by researchers at the University of Cambridge published in Nature’s npj |Climate Action series.  AI computer programmes used for climate science are trained to trawl through complex datasets looking for patterns and insightful information. However, missing information from certain locations on the planet, time periods or societal dynamics create “holes” ...

The AI model was more efficient at detecting signatures of atrial septal defect (ASD) in electrocardiograms (ECG) than traditional methods. Investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, and Keio University in Japan have developed a deep learning artificial intelligence model to screen electrocardiogram (ECG) for signs of atrial septal defects (ASD). This condition can cause heart failure and is underreported due to a lack of symptoms before irreversible complications arise. Their results are published in eClinicalMedicine. "If we can deploy our model on a population-level ECG screening, ...

How do children and adolescents evaluate and reason about acts of physical violence in the context of chronic violence that impacts their communities? Previous studies have used situations that correspond with a single act of interpersonal harm void of broader conditions of violence shaping the context in question. A new study released in Child Development examined how youth exposed to gangs known as maras (e.g., MS 13) in Honduras morally deliberate about conditions of gang violence compared with youth not exposed to gangs in Nicaragua, where there are very few maras ...

According to the World Health Organization, globally, infectious disease is a leading cause of death among children. Furthermore, children are more likely than adults to contract infectious illnesses. However, there’s a gap in research measuring children’s responses to sick faces. It is important to understand how children’s ability to recognize and avoid sickness emerges and develops to help improve children’s health and public health more broadly. Previous research has only reported that adults can use faces to recognize if someone is sick and make judgments about whether to approach or avoid them.  Researchers from the University ...

PHILADELPHIA – Patients with pancreatic cancer who took the benzodiazepine lorazepam (Ativan), commonly prescribed to treat anxiety during cancer treatment, had a shorter progression-free survival than patients who did not, according to results published in Clinical Cancer Research, a journal of the American Association for Cancer Research (AACR). In contrast, patients who took the benzodiazepine alprazolam (Xanax) had a significantly longer progression-free survival than patients who did not. Benzodiazepines are a class of drugs that suppress the activity of the central nervous system, which can relieve ...

Reasoning skills are crucial skills in learning, academic performance, and everyday problem-solving. According to a recent study conducted at the University of Eastern Finland, improved overall diet quality and reduced consumption of red meat, as well as increased time spent in reading and organised sports enhanced reasoning skills among children over the first two school years. “Children with healthier eating habits showed greater cognitive development than other children. Specifically, better overall diet quality, ...

Humans have a positive view of nature. But is this due to an approach we have learned while growing up, or is it something we are born with? The answer is ‘Both’, according to researchers at the University of Gothenburg and the Swedish University of Agricultural Sciences. Our love of nature is highly individual and should influence how we plan our cities, say the researchers. It is well known that nature has a positive effect on people. In cities in particular, studies have shown that trees and other greenery contribute to people’s wellbeing. However, experts do not agree on the reasons behind this phenomenon, known ...

Researchers are using mathematical models to better understand the effects of disruptions like daylight savings time, working night shifts, jet lag or even late-night phone scrolling on the body’s circadian rhythms. The University of Waterloo and the University of Oxford researchers have developed a new model to help scientists better understand the resilience of the brain’s master clock: the cluster of neurons in the brain that coordinates the body’s other internal rhythms. They also hope to suggest ...

A joint research team from LKS Faculty of Medicine, the University of Hong Kong (HKUMed) and City University of Hong Kong (CityU) has generated human neural stem cells with powerful therapeutic potential for the treatment of spinal cord injury that paves the way for new therapeutic opportunities. The new findings are now published in the leading multidisciplinary science journal, Advanced Science [link to publication]. Background Traumatic spinal cord injury (SCI) commonly caused by a car accident, fall, or sport-related accident results in the progressive loss of neurons involved in motor and sensory functions at and around ...

Introduced foxes, dogs, cats, rats, and other predators kill millions of native animals every year, but what if they were conditioned to associate this prey with food that made them ill? A team of international researchers have shown the potential to do just that, burying baits containing capsules of levamisole, a chemical that induces nausea and vomiting when consumed by predators. In a world first experiment conducted in south-eastern Australia, where introduced red foxes are responsible for countless wildlife deaths, the Australian National University (ANU) and University of South Australia scientists laid baits of fried deboned chicken, with some containing ...

What if artificial intelligence (AI) could be used to spur discovery in areas such as biotechnology, drug discovery and fluid dynamics? Using geometric graphs and innovative methodologies, AI can solve fundamental problems in basic natural science. The possibilities are endless in this relatively new field known as AI for science. Dr. Shuiwang Ji, a professor in the Department of Computer Science and Engineering at Texas A&M University, recently received a National Science Foundation grant to ...

(Philadelphia, PA) – A single injection of a novel CRISPR gene-editing treatment safely and efficiently removes SIV – a virus related to the AIDS-causing agent HIV – from the genomes of non-human primates, scientists at the Lewis Katz School of Medicine at Temple University now report. The groundbreaking work complements previous experiments as the basis for the first-ever clinical trial of an HIV gene-editing technology in human patients, which was authorized by the Food and Drug Administration (FDA) in 2022. The preclinical study, published online ...

As urban areas expand, animals increasingly find themselves living in towns and cities. While some animals may benefit from milder temperatures and fewer natural predators in urban settings, they also have to cope with pollutants and changes in their diet. Previous research has shown that animals in cities are “duller” in terms of yellow-orange-red colour tones compared to their non-urban counterparts. However, previous studies have only focused on single geographic locations. “We used feather samples collected from great tits in cities and forests across Europe. Different methods all confirmed that urban great tits ...

(Santa Barbara, Calif.) — We’ve managed to accumulate so much plastic trash that it’s daunting to think about what could be done with the tons upon tons of nonbiodegradable waste. And as much as we are trying to scale back our dependence on single-use plastics, we continue to add to the global plastic trash hoard. Events like the COVID-19 pandemic only served to expand their use for personal protective equipment and disposable and take-away packaging. But, for researchers at UC Santa Barbara, one person’s single-use packaging ...

Group A streptococci are fairly common bacteria that can cause, among other things, strep throat or impetigo. However, if the bacteria become invasive, the situation can become very dangerous. In this case, the name sometimes changes to murder bacteria or flesh-eating bacteria and can give rise to life-threatening conditions such as blood poisoning and septic shock, or soft tissue infections that may make an amputation necessary. Invasive streptococcal infections have increased in recent decades. The reason for this is not fully understood.  The outcome of infections can ...

Prolonged exposure to low-dose ionising radiation is associated with a higher risk of death from cancer than previously thought, suggests research tracking the deaths of workers in the nuclear industry, published in The BMJ today. The findings should inform current rules on workplace protection from low-dose radiation, say the researchers. To date, estimates of the effects of radiation on the risk of dying from cancer have been based primarily on studies of survivors of atomic bombs dropped on Japan at the ...

Access to a smartphone alcohol intervention app helped university students to cut down their overall alcohol consumption and the number of days they drank heavily, suggests a study published in The BMJ today. Unhealthy drinking is the biggest risk factor to health for 15 to 49-year olds, and unhealthy use of alcohol is especially prevalent among adult students, prompting the authors to design a smartphone app to encourage healthier drinking among this group. The authors tested the app in 1770 university students who had screened positive for ...

*Please see end of press release for a link to the embargoed content* Peer-reviewed / Randomised Controlled Trial / People A randomised controlled trial of 860 women requesting emergency contraception found 95% of pregnancies were prevented following combined treatment with levonorgestrel and the anti-inflammatory medication piroxicam, compared to 63% of pregnancies being prevented when levonorgestrel was taken alone. This is the first randomised trial where piroxicam has been studied for its contraceptive action in humans. The authors say, if these results can be reproduced in future studies, co-treatment with piroxicam and levonorgestrel ...

Osaka, Japan - What if “looking your age” refers not to your face, but to your chest? Osaka Metropolitan University scientists have developed an advanced artificial intelligence (AI) model that utilizes chest radiographs to accurately estimate a patient’s chronological age. More importantly, when there is a disparity, it can signal a correlation with chronic disease. These findings mark a leap in medical imaging, paving the way for improved early disease detection and intervention. The results are set to be published in The Lancet Healthy Longevity. The research team, led by graduate student ...

Epilepsy in infants ranges in severity and can leave caregivers with questions about their child’s health. While genetic testing to help determine the cause of epilepsy is possible, comprehensive testing does not always happen routinely and it can take a long time, leaving families waiting for answers.  Published in The Lancet Neurology, this international study sequenced the genomes of 100 infants with unexplained seizures, along with their parents, from four countries (England, USA, Canada and Australia) to better understand the potential strengths of early, broad genome sequencing (a process ...

The BMJ’s editor in chief is urging the Academy of Medical Royal Colleges and its members to establish a standard for declaring payments they receive from industry and patient groups in the wake of a recent investigation by The BMJ into such payments. The investigation, published by The BMJ in July,* found that royal colleges, responsible for doctors’ and some other healthcare professionals’ education and training, had received more than £9m in payments from drug and medical device companies since 2015 but that they didn’t always disclose these payments publicly in their annual reports. In an open letter to the institutions ...

Fresh evidence of ChatGPT’s political bias revealed by comprehensive new study The artificial intelligence platform ChatGPT shows a significant and systemic left-wing bias, according to a new study by the University of East Anglia (UEA). The team of researchers in the UK and Brazil developed a rigorous new method to check for political bias. Published today in the journal Public Choice, the findings show that ChatGPT’s responses favour the Democrats in the US, the Labour Party in the UK, and in Brazil President Lula da Silva of the Workers’ Party. Concerns ...

An extremely rare collection of 160-million-year-old sea spider fossils from Southern France are closely related to living species, unlike older fossils of their kind. These fossils are very important to understand the evolution of sea spiders. They show that the diversity of sea spiders that still exist today had already started to form by the Jurassic. Lead author Dr Romain Sabroux from the University of Bristol’s School of Earth Sciences, said: “Sea spiders (Pycnogonida), are a group of marine animals that is overall very poorly studied. “However, ...
