A research team led by Professor Sei Kwang Hahn and Dr. Tae Yeon Kim from the Department of Materials Science and Engineering at Pohang University of Science and Technology (POSTECH) used gold nanowires to develop an integrated wearable sensor device that effectively measures and processes two bio-signals simultaneously. Their research findings were featured in Advanced Materials.

Wearable devices, available in various forms like attachments and patches, play a pivotal role in detecting physical, chemical, and electrophysiological signals for disease diagnosis and management. Recent strides in research focus on devising wearables capable of measuring multiple bio-signals concurrently.

However, a major challenge has been the disparate materials needed for each signal measurement, leading to interface damage, complex fabrication, and reduced device stability. Additionally, these varied signal analyses require further signal processing systems and algorithms.

EMotorad, an Indian startup manufacturing electric bikes, raised $20 million in a Series B round as it aims to disrupt China’s market domination and expand its presence in global markets.

The three-year-old startup has raised more than $22.5 million in total funding, with Singapore’s Panthera Growth Partners leading the latest round, along with participation from Alteria Capital, xto10x Technologies, and Green Frontier Capital — the startup’s existing investor. Additionally, the fresh funding round includes a debt of $2.5 million.

The demand for e-bikes is growing in markets beyond China and India as people seek to reduce their reliance on fossil fuels, ease traffic congestion on the roads and find alternative transportation options that do not require rigorous physical activity throughout their daily commute. In 2021, the World Bank predicted (PDF) that as many as 300 million e-bikes will circulate in cities across the globe by 2023. However, despite growing demand worldwide, e-bike supplies rely heavily on Chinese manufacturers. EMotorad is striving to overturn this trend by establishing its manufacturing operations in India.

Tesla Investor Relations (IR) Head Martin Viecha has provided some key details about the upcoming Cybertruck first delivery event, which is scheduled to be held at Gigafactory Texas this Thursday, November 30, 2023. Contrary to other Tesla events like the Cyber Rodeo, the Cybertruck’s first deliveries will be starting notably earlier.

As noted by Martin Viecha, the Tesla Cybertruck delivery event will be starting at 1 p.m. CT (11 a.m. PST). Expectations are high that Tesla will be live-streaming the event, though the executive has not provided information about when the livestream for the occasion will go live.

“The Cybertruck delivery event starts at around 1 p.m. CT on Thursday, in case someone’s unsure. I’ve noticed that few people thought it’s an evening event,” Viecha clarified on X, the social media platform formerly known as Twitter.

The approach uses machine vision to 3D print structures with multiple materials, from hard, bone-like substances to stuff that’s more like soft tissues.

In a recent study published in the journal Scientific Reports, researchers compare whether insulin-and non-insulin-based insulin resistance (IR) markers could predict the risk of non-alcoholic fatty liver disease (NAFLD) in obese and non-obese individuals with no history of diabetes or hepatitis.

About 10–15% of pregnancies fail after conception has been recognized, amounting to 23 million losses a year. Chromosomal anomalies underlie many embryonic and fetal losses, but their exact frequency and localization to the embryo or placenta are still unclear. A new study published in Nature Medicine reports on a chromosomal analysis of over 1,700 spontaneous early miscarriages.

The most common period of pregnancy loss is before the ninth week, though many may occur earlier and pass unrecognized. While about 11% of women have at least one miscarriage, the proportion goes down with two or three, at 2% and 0.7. respectively.

Hydrogen is having a moment, thanks to Biden administration incentives to boost production — and that’s spurring development of hydrogen-powered transport, including drones.

Why it matters: Hydrogen-powered drones could potentially fly farther and carry bigger payloads than those relying on heavy electric batteries. That opens doors to new uses, like advanced logistics.

Driving the news: Israeli startup Heven Drones unveiled today two new hydrogen-powered drones that it says represent “a significant leap in endurance and precision.”

A Texas undergrad is investigating how to grow vegetables on Mars — and has cultivated test samples of English peas in simulated Martian soil, with fertilizer from fly larvae.
