Researchers at Tufts University’s School of Engineering have developed biomaterial-based inks that respond to and quantify chemicals released from the body (e.g. in sweat and potentially other biofluids) or in the surrounding environment by changing color. The inks can be screen printed onto textiles such as clothes, shoes, or even face masks in complex patterns and at high resolution, providing a detailed map of human response or exposure. The advance in wearable sensing, reported in Advanced Materials, could simultaneously detect and quantify a wide range of biological conditions, molecules and, possibly, pathogens over the surface of the body using conventional garments and uniforms.

“The use of novel bioactive inks with the very common method of screen printing opens up promising opportunities for the mass-production of soft, wearable fabrics with large numbers of sensors that could be applied to detect a range of conditions,” said Fiorenzo Omenetto, corresponding author and the Frank C. Doble Professor of Engineering at Tufts’ School of Engineering. “The fabrics can end up in uniforms for the workplace, sports clothing, or even on furniture and architectural structures.”

DARPA is developing bioelectronic devices that would dwell in the gut and produce therapeutic drugs on demand.

By drawing inspiration from the structures and functionalities of squid skin cells, a team of researchers designed and engineered human cells that contain stimuli-responsive photonic architectures and, as a consequence, possess the ability to change their appearance and transmission of light.

This work on one-cell embryos could advance our knowledge of the mechanisms that underpin cellular behaviour in general, and may ultimately provide insights into what goes wrong in aging and disease.

For the first time, scientists have added microscopic tracking devices into the interior of cells, giving a peek into how development starts.

Like all countries, China is facing severe economic losses from the pandemic, and that will certainly have a negative impact on scientific research, because funding will be reduced and projects will be delayed, says physicist Wang Yifang, director of the Institute of High Energy Physics in Beijing. Some universities have already announced a cut in funding. The research budget given by the education ministry to Jiangnan University in Wuxi, for example, will drop by more than 25% for 2020, and other universities are facing similar reductions. “An overall budget cutting of government spending on higher education is highly possible, though the level and scope may vary by regions, universities and fields,” says Tang Li, a science-policy scientist at Fudan University in Shanghai.

The country is rapidly gaining on the United States in research, but problems could slow its rise: part 5 in a series on science after the pandemic.

When it comes to monitoring electrical activity in the brain, patients typically have to lie very still inside a large magnetoencephalography (MEG) machine. That could be about to change, though, as scientists have developed a new version of a wearable helmet that does the same job.

Back in 2018, researchers at Britain’s University of Nottingham revealed the original version of their “MEG helmet.”

The 3D-printed device was fitted with multiple sensors that allowed it to read the tiny magnetic fields created by brain waves, just like a regular MEG machine. Unlike the case with one of those, however, wearers could move around as those readings were taking place.

A team of researchers from several U.S. institutions has created an organoid culture system that generates complex skin from human pluripotent stem cells.

New research using ancient DNA is rewriting prehistory in India — and shows that its civilisation is the result of multiple ancient migrations, writes Tony Joseph.

Who are the Indians? And where did they come from?

Rapamycin, a drug that has life-extending effects on mice (and possibly dogs and humans), also reverses age-related dental problems in mice. 🦷 Out now in eLife from researchers at The University of Washington School of Dentistry & JAX’s Kaczorowski Lab:

Rapamycin, which has life-extending effects on mice, also reverses age-related dental problems such as periodontitis and regrows bones in the animals.
