MITâs quantum tunneling transistors achieve high performance and energy efficiency, surpassing siliconâs limits with nanoengineering.
New energy-harvesting nanogenerators may power IoT devices, sensors, and wearables using everyday mechanical movements.
This was first predicted by Omni magazine in 1981.
In the world of medicine, the ability to listen to the intricate symphony of sounds within the human body has long been a vital diagnostic tool. Physicians routinely employ stethoscopes to capture the subtle rhythms of air moving in and out of the lungs, the steady beat of the heart, and even the progress of digested food through the gastrointestinal tract.
These sounds hold valuable information about a personâs health, and any deviations from the norm can signal the presence of underlying medical issues. Now, a groundbreaking development from Northwestern University is set to transform the way we monitor these vital sounds.

New therapies for managing aging could emerge from research into a new gene, which scientists have identified as a key driver of degeneration.
Age-related diseases are strongly linked to inflammation which, when chronic, albeit low-grade, contributes to conditions such as cardiovascular disease, diabetes, neurodegeneration, and sarcopenia, significantly impacting health and longevity.
In a study published in Nature Communications, Dr. Ildus Akhmetov, a geneticist at Liverpool John Moores Universityâs School of Sport and Exercise Sciences, along with colleagues from Italy, Switzerland, and the Netherlands, uncovered groundbreaking insights into the role of the Ectodysplasin A2 Receptor (EDA2R) in this process.
The Earthâs magnetic field, a constant presence in our environment, has a subtle yet profound impact on human health. It operates at extremely low frequencies (around 7.83 Hz, known as the Schumann resonance) and low intensities (30â60 microTesla). Generated by electric currents in the conductive iron alloys in Earthâs core, this magnetic field protects us from a blast of solar particles (solar wind) that could literally obliterate life on Earth if allowed to enter our atmosphere (Figure 1). It also plays a crucial role in regulating our circadian rhythms and supporting overall cellular function. Our cells are used to living bathed in this interactive field of magnetism and electricity, and therapeutically, we can turn this into our advantage.

Most deaths avoided from common cancers between 1975 and 2020 could be traced to prevention and screening efforts.
Slippery proteins in the brainâs blood vessels form a protective barrier that breaks down with age, studies in mice show.
