Synthetic biology reinvents development

Researchers have developed a new type of model using synthetic biology to replicate symmetry breakage observed in embryos, enabling the creation of complex structures. The study identified essential parameters that modulate spatial pattern emergence in E. coli, paving the way for understanding embryonic development.

The first steps toward a quantum brain

Researchers at Radboud University create a network of single atoms that mimic brain-like behavior and adapt to external stimuli. They plan to scale up the system and explore new materials to build self-learning computing devices.

Just add mushrooms: Making meals more nutritious

Researchers found that adding a serving of mushrooms increased micronutrient intake, including potassium and fiber, without affecting calorie, fat, or sodium content. Mushrooms also provided vitamin D, copper, phosphorus, selenium, zinc, and other essential nutrients.

SAMSUNG T9 Portable SSD 2TB

SAMSUNG T9 Portable SSD 2TB transfers large imagery and model outputs quickly between field laptops, lab workstations, and secure archives.

Alternate type of surgery may prevent total knee replacement

A new study published in CMAJ found that high tibial osteotomy is successful in reducing the need for total knee replacement in younger patients with early-stage knee osteoarthritis. The procedure delays or prevents knee replacement in up to 79% of patients within 10 years.

Apple iPhone 17 Pro

Apple iPhone 17 Pro delivers top performance and advanced cameras for field documentation, data collection, and secure research communications.

Magnetic signature of giant magnetofossils

Scientists use low-noise magnetic measurements to detect giant magnetofossils in bulk sediment samples, shedding light on ancient environments and organisms' physiology. The high-coercivity signature identified is consistent with needle-shaped fossils found in sediments, providing new insights into the geological record.

Searching for dark matter through the fifth dimension

Researchers propose a new theory that predicts the existence of a new force between ordinary and dark matter, making dark matter accessible to forthcoming experiments. The 5-dimensional field equations also predict the existence of a heavy particle with similar properties as the Higgs boson but a much heavier mass.

Paving the way for effective field theories

Effective field theories offer a unified description of complex systems, including atomic nuclei and biological systems. The collected studies demonstrate the relevance of these ideas to low-energy nuclear processes, paving the way for new advances in this field.

Aranet4 Home CO2 Monitor

Aranet4 Home CO2 Monitor tracks ventilation quality in labs, classrooms, and conference rooms with long battery life and clear e-ink readouts.

Your toothbrush reflects you, not your toilet

A Northwestern University study found that bacteria on used toothbrushes reflect microbial communities in the mouth and skin, not the toilet. The research, published in Microbiome journal, suggests that microbes from the human body are transferred to toothbrushes through saliva and other bodily fluids.

Batteries that can be assembled in ambient air

Researchers at Pohang University of Science & Technology developed a multi-functional separator to trap moisture and impurities in lithium-ion batteries. This breakthrough allows for battery assembly in ambient air, reducing costs and improving performance, with excellent heat resistance and electrochemical stability demonstrated.

Creality K1 Max 3D Printer

Creality K1 Max 3D Printer rapidly prototypes brackets, adapters, and fixtures for instruments and classroom demonstrations at large build volume.

COVID-19 news from Annals of Internal Medicine

Taiwan's rapid response to COVID-19 has led to a decrease in overall death rates compared to 2019, suggesting mask-wearing and physical distancing had a positive impact. Immunization experts also call on clinicians to utilize immunization information systems to facilitate fair and equitable COVID-19 vaccine distribution.
