Blame and Compliance: Just deserts and support for lockdowns in the time of COVID-19

A study by Osaka University found that belief in just deserts (BJD) was highest in Japan and lowest in the UK, while human rights restriction (HRR) was highest in China and lowest in Japan. The research suggests that BJD and HRR are positively correlated in some countries, leading to increased disease-related prejudice and discrimination.

Great expectations vs reality of food healthiness in online grocery shopping

A new study found that consumers tend to write negative reviews when their expected and actual nutritional values for food products do not match. This mismatch is the number one driver of negative reviews on online grocery sites. Consumers may be misinformed about the healthiness of foods due to inadequate nutritional information.

Study reveals high accuracy of MR-guided radiotherapy for intracranial stereotactic radiosurgery

Researchers demonstrated the accuracy of an MR-guided radiotherapy system for intracranial stereotactic radiosurgery, achieving up to 99% precision in treating brain tumors. The study enables novel MR-guided radiotherapy technology for intracranial SRS, which has not been used with MR Linac systems.

Scientists identify evolutionary gateway helping pneumonia bacteria become resistant to antibiotics

Researchers at the University of Sheffield have discovered a genetic scar that enables pneumonia-causing bacteria to become resistant to antibiotics. The study found that mutations in the pde1 gene act as an evolutionary gateway for this resistance, threatening patient treatment and highlighting the need for control measures.

Differences in mortality rates for fatal cerebral haemorrhage between Finnish university hospitals

A study of nearly 10,000 subarachnoid hemorrhage cases in Finland found significant variations in mortality rates among university hospital districts. Patients treated at Helsinki University Hospital and Oulu University Hospital had the lowest mortality rates, with a difference of 52% compared to Turku University Hospital.

Pheromones influence death feigning behavior in beetles

Researchers found that exposure to the aggregation pheromone 4,8-dimethyldecanal reduces death-feigning duration in red flour beetles, allowing them to save time and increase survival chances. Sex-related differences in death feigning behavior were also observed, with males exhibiting longer durations.

DeepMB: a deep learning framework for high-quality optoacoustic imaging in real-time

Researchers have developed DeepMB, a neural network that reconstructs high-quality optoacoustic images about 1,000 times faster than state-of-the-art algorithms. This enables clinicians to access optimal MSOT image quality in real-time, positively impacting clinical studies and patient care.

Shorter course of radiation therapy is safe for patients with early-stage breast cancer who have undergone mastectomy and reconstruction

Researchers found a shorter course of radiation therapy provides equivalent protection against breast cancer recurrence and physical side-effects, but reduces life disruption and financial burden. Patients reported less burden on their time and finances, with improved quality of life.

Study indicates possible link between chronic stress and Alzheimer’s disease

A study published in Alzheimer's Research & Therapy suggests a possible association between chronic stress and an increased risk of developing mild cognitive impairment or Alzheimer's disease. The research, conducted on 44,447 individuals between 18-65 years old, found that those with chronic stress or depression had a higher risk of d...

Metaphors for human fertilization are evolving, study shows

A new study by Yale sociologist Rene Almeling found that despite the shift in social and scientific views on gender, sex, and sexuality, a common metaphor of active sperm penetrating a passive egg remains widely used. However, another more egalitarian metaphor describing sperm and egg as two halves of a whole is also circulating.

Give abandoned croplands a second chance to boost climate mitigation and food security, urges new study

Researchers found that globally abandoned cropland could feed up to 476 million people per year if recultivated and help pull planet-warming carbon dioxide from the atmosphere through reforestation. The study highlights the potential of this often-neglected resource in supporting both food security and climate change mitigation.

Exposure to daylight rather than artificial light improves blood sugar control and nutrient use in individuals with type 2 diabetes, small Dutch study finds

A small Dutch study found that exposure to natural light improved blood sugar control and nutrient use in individuals with type 2 diabetes. The study showed that participants experienced better blood sugar levels, increased fat as an energy source, and improved clock gene expression when exposed to natural light.

Immune cell map reveals origin of subcellular response to microbes, researchers report

Researchers have created an 'immune cell map' that reveals the origin of neutrophils' subcellular response to microbes. The study found that a specific type of glycoprotein is responsible for the restricted subcellular origin, and this discovery may lead to refined personalized immune responses.
