Scientists have developed a novel strategy for improving the lateral resolution of optical microscopy by fabricating high-quality micro-spheres using laser-based 3D printing. This development offers a cost-effective alternative to expensive microscopy solutions, potentially revolutionizing the field with custom-designed devices that enhance resolution for any optical microscope.

The production of antibodies, crucial for fighting infections, is tightly regulated by follicular helper lymphocytes. Researchers, led by Luís Graça, uncovered two distinct groups of these cells: one promoting antibodies against viruses, the other against parasites and allergies.

While mentally stimulating activities and life experiences can improve cognition in memory clinic patients, stress undermines this beneficial relationship. This is according to a new study from Karolinska Institutet published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.

Asahi Kasei Medical's subsidiary Bionova Scientific has plans to launch a plasmid DNA business and for this it will develop a new facility in Texas, USA. The unit is scheduled to begin in the first quarter of 2025 for process development and later in 2025 for GMP manufacturing.

Researchers have conducted a study which helps to detect early signs of dementia by studying the natural speech of seniors. They revealed that participants with memory-related mild cognitive impairment spoke less and used fewer, but more abstract, nouns that is consistent with the speech pattern of Alzheimer’s patients.

For the first time, water frost has been detected atop the Tharsis volcanoes on Mars, which is considered as the tallest volcanic mountains in the entire solar system.

Using artificial intelligence technology to identify patterns of DNA fragments associated with lung cancer, researchers from the Johns Hopkins Kimmel Cancer Center and other institutions have developed and validated a liquid biopsy that may help identify lung cancer earlier.

A new study has revealed that people with persistently higher levels of omega-6 as compared to omega-3 fatty acids in their blood, as well as consistently low DHA levels, had more psychotic experiences at age 24.

A new lightweight sensor system with infrared imaging, developed by an international engineering team, can be mounted on drones for remote crop monitoring. This flat-optics technology could replace traditional lenses in environmental sensing, helping farmers precisely manage irrigation, fertilization, and pest control, potentially leading to cheaper groceries and higher yields.

From the outside, most T cells look the same: small and spherical. Now, a team of researchers from the Institute of Molecular Systems Biology at ETH Zurich has taken a closer look inside these cells using advanced techniques. Their findings show that the subcellular spatial organisation of cytotoxic T cells has a major influence on their fate.
