Cricket umpires fumble on T20 calls

Research by Queensland University of Technology reveals that elite-level cricket umpires make more errors when making leg-before-wicket (LBW) decisions in T20 cricket, with a hit rate of 86.15% and false alarm rate of 2.04%. The study found that the format of the game affects decision-making behavior.

Excess weight among pregnant women may interfere with child's developing brain

Research published in Journal of Child Psychology and Psychiatry suggests that obesity in pregnant women can affect the developing brain, particularly in areas responsible for decision-making and behavior. The study used fetal brain activity measurements to identify potential links between maternal BMI and changes in brain connectivity.

COMBAT study preliminary results show response of 32% in treatment of pancreatic tumors

The COMBAT trial, a phase IIa clinical trial, has shown promising results with pembrolizumab and BL-8040 combination therapy, achieving a 32% meaningful tumor shrinkage in patients with metastatic pancreatic cancer. This response rate is double that of traditional chemotherapy, offering hope for improved treatment outcomes.

'Insect apocalypse' may not be happening in US

A recent US long-term ecological site study suggests that the so-called 'insect apocalypse' may be exaggerated, with many areas showing little to no overall change in insect abundance and biodiversity. However, certain species remain in decline, particularly for key ecosystem services like pollination and natural pest control.

COVID-19 clinical trials lack diversity

Majority of patients in remdesivir trials were Caucasians, raising concerns about medication efficacy in people of color. The study emphasizes the need for diverse clinical trial participants to accurately represent the US population and inform treatments.

Researchers explore pollen fertilization mechanisms

A study published in Nature Communications reveals how pollen tubes grow up to a thousand-fold to reach the ovule, creating electrical activity at the cell membrane and promoting faster growth. The findings have implications for understanding seed production, fungal growth, and neuronal development, and may lead to improved food crop v...

Evolutionary theory of economic decisions

A new study from Stanford University proposes that the brain was constructed over evolutionary history to make high-stakes decisions with a bias towards pessimism. This perspective challenges traditional economic models, which assume humans act rationally and weigh probabilities to maximize personal gain.

Physicists cast doubt on neutrino theory

Researchers from University of Cincinnati and Fermi National Accelerator Laboratory failed to detect sterile neutrinos in twin experiments, increasing doubts about their existence. The study's findings suggest that sterile neutrinos might not be responsible for previously observed anomalies.

COVID-19: Herd immunity in Sweden fails to materialize

Sweden's policy of controlled spread of COVID-19 has failed to deliver herd immunity, with actual antibody prevalence lower than predicted. Clinical findings suggest that mildly ill or asymptomatic patients are less likely to acquire antibodies.

Right under your nose: A more convenient way to diagnose Alzheimer's disease

Scientists at DGIST discovered that specific proteins in nasal discharge can indicate the onset and progression of Alzheimer's disease, providing a novel approach for early detection. The levels of two particular Aβ oligomers were consistently higher in patients with AD, allowing for non-invasive screenings to assess AD progression.

Individual differences in the brain

Scientists selectively bred zebrafish to exhibit distinct personality traits, finding that brain activities soon changed and new brain regions were activated. The study suggests a rapid pace of personality trait changes and potential implications for human behavior.

Nepal lockdown halved health facility births and increased stillbirths and newborn deaths

A new study reveals that the COVID-19 lockdown in Nepal resulted in a 49.9% decrease in health facility births, leading to increased stillbirth rates by 50% and neonatal mortality by over 3-fold. The lockdown had a disproportionate impact on vulnerable populations, highlighting the need for improved maternal and newborn healthcare duri...
