Follow-up by trained nurses helps myocardial infarction patients

A case management program with trained nurses improves the health of elderly patients after a cardiac infarction, reducing physical restrictions and improving lifestyle changes. The study analyzed data from over 300 patients aged 65 years or older, finding positive effects on muscle strength, blood fat levels, and overall quality of life.

Closing the carbon loop

A new catalyst developed by researchers at the University of Pittsburgh has the potential to solve two problems at once - reducing net carbon dioxide emissions while generating cleaner fuels. The catalyst, which converts CO2 into methanol, could dramatically reduce the cost of carbon capture and conversion.

Knowing one's place in a social hierarchy

A study published in Neuron reveals the mechanisms behind learning social hierarchies, with the prefrontal cortex playing a key role. The researchers found that people can rapidly form coherent understandings of their own social hierarchy through integrating interaction outcomes.

Miraculous proliferation

Recent experiments by Loessner and his group have shown that L-forms are an independent form of life that can multiply indefinitely. They form a crazy network of vesicles with elastic connector tubes, enabling them to exchange cytoplasm and multiply without cell walls or genetic material.

Deep brain stimulation may not boost memory

A recent study published in Neuron found that deep brain stimulation did not improve memory performance, with a range of impairment from 5% to 20%. However, the researchers suggest that a different stimulation protocol may be necessary to boost memory.

Decoding cement's shape promises greener concrete

Rice University scientists have decoded the kinetic properties of cement and developed a way to 'program' microscopic particles to create less porous and more durable material. This technique may lead to stronger structures that require less concrete, reducing greenhouse gas emissions.

Safety in darkness

A Kyoto University team has demystified the process of melanin transport to epidermis using video cameras and chicken tissue. Melanin pigments protect skin from DNA damage by surrounding keratinocyte nuclei, a discovery that could lead to effective dermatological treatments.

Doctors need to develop broader skill of empathy

Developing a broader skill of empathy is crucial for medical students and doctors, enabling them to strike a balance between compassion and clinical detachment. This approach, driven by Dr David Jeffrey's work, enables improvements in patient care, psycho-social research, and medical education.

Body composition may affect older women's risk of urinary incontinence

A study found that higher body mass index (BMI) and fat mass are significant markers of risk for stress- and urgency urinary incontinence (SUI and UUI) in older women. Women who lost at least 5% of their BMI or fat mass were less likely to experience new or persistent SUI over a three-year period.

Uterine microbiota play a key role in implantation and pregnancy success in in vitro fertilization

A new study found that women with a Lactobacillus-dominated microbiota in their uterine cavity had significantly lower rates of implantation, pregnancy, and live birth compared to those with non-Lactobacillus-dominated microbiota. This research suggests that the endometrial microbiome may play a crucial role in reproductive success.
