Relative correction of experimental results as training data are crucial for optimizing culture media using machine learning

Cell culture medium optimization is crucial for effective growth of cells, as the medium determines the culture results. Researchers developed a machine learning model that optimizes the composition of the medium based on training data, achieving higher cell concentrations than commercially available media.

Body appreciation varies across cultures

A study published in PLOS ONE found that body appreciation varies across cultures, with significant differences between Western and non-Western countries. Black Nigerian women reported the highest level of body appreciation, while White Western women reported the lowest. The study also found that internalization of thin ideals and soci...

“Peace speech” in the media characterizes a country’s peaceful culture

A new study found that high-peace countries are characterized by an increased prevalence of words related to optimism for the future and fun, while low-peace countries feature more references to control and fear. The research used a machine learning model to identify these linguistic patterns in media articles from 18 countries.

Children’s nature drawings reveal a focus on mammals and birds

UK schoolchildren aged 7-11 drew mammals and birds most commonly, with reptiles and amphibians appearing less frequently. The study suggests children's perceptions of local wildlife are skewed towards mammals and birds, hinting at a wider problem of nature disconnect.

Growing blood stem cells in the lab to save lives

A team led by Professor Satoshi Yamazaki has established a novel culture system that supports long-term ex vivo expansion of human hematopoietic stem cells (HSCs), overcoming previous limitations. The new system, which uses chemically-defined cell culture media, significantly improves HSC growth and proliferation.

Droplet-array sandwiching technology: Making versatile biochemical tools out of droplets

Researchers at Ritsumeikan University have created a technique to precisely control the concentration of chemicals in droplets using electrowetting-on-dielectric (EWOD). This allows for accurate drug screening and cell-based analysis, enabling the efficient handling of substances on a smaller scale than traditional pipettes.

Pernicious effects of stigma

Researchers found that negative stereotype exposure leads to altered brain activity in the nucleus accumbens, affecting anticipation of rewards and punishments. This study sheds light on the psychological fatigue and stress associated with stigmatization, which can contribute to depression and other mental health issues.

Peering into a more 'human' petri dish

Cell culture media has remained relatively unchanged for over 70 years, but Jason Cantor is developing 'physiologic media' that closely mimics real biological conditions. This allows researchers to study cell behavior in a more accurate and relevant way, potentially revealing fundamental insights into human diseases such as blood cancer.

Scientists create functioning kidney tissue

Scientists at the University of Manchester successfully produced human kidney tissue within a living organism that is able to produce urine. The new structures contain most of the constituent parts present in human nephrons, including proximal tubules and Bowman's capsule, and have been linked to the vasculature of mice.
