Study: Resilience in parents of children undergoing stem cell transplant

A recent study published in Biology of Blood and Marrow Transplantation found that parents of children undergoing stem cell transplant experience increased distress during the procedure but recover to normal levels of adjustment. Parents demonstrate remarkable recovery despite facing significant life challenges.

How to make the wonder material graphene superconducting

Scientists at the University of Vienna have unveiled the superconducting pairing mechanism in calcium-doped graphene using the Angle-resolved photoemission spectroscopy (ARPES) method. The findings reveal that calcium is the most promising candidate to induce superconductivity in graphene, with a critical temperature of about 1.5K.

Males and females differ in specific brain structures

A recent meta-analysis of 20 years of neuroscience research reveals significant sex differences in brain structure, with males on average having larger total brain volumes and higher tissue densities in certain regions. Females, on the other hand, have higher density in the left frontal pole and larger volumes in other areas.

Child abuse rises with income inequality, study shows

A nationwide study by Cornell researchers found that child abuse and neglect are associated with income inequality, affecting 3.4 million children under 18 years old each year. The study also highlighted the long-term effects of childhood maltreatment, including increased rates of unemployment and substance use.

Acidic tumor pH inhibits drug effect

A new study from Karolinska Institutet found that acidic tumor pH counteracts chloroquine's ability to inhibit autophagy in cancer cells. The results may explain the lack of efficacy of chloroquine in clinical studies, particularly in tumors with low oxygen and acidic pH.

Nanoparticles treat muscular dystrophy in mice

Scientists at WashU Medicine have developed a new approach to treating muscular dystrophy, using nanoparticles loaded with rapamycin to improve recycling of cellular waste. The treatment showed significant improvements in skeletal muscle strength and cardiac function in mice with Duchenne muscular dystrophy.

Exercise may slow retinal degeneration

Researchers found that moderate aerobic exercise helps preserve retina structure and function after damage. Exercise was shown to have a direct effect on retinal health and vision, potentially leading to tailored exercise regimens or combination therapies for retinal degenerative diseases.

First 3-D movies of living sperm

Researchers have developed a new tracking system that takes 3-D movies of living sperm, providing detailed imaging and analyzing motility data. The method helps detect potential infertility-causing anomalies, such as bent tails, and may soon aid in vitro fertilization (IVF) clinics in selecting the most viable sperm cells.
