The different colors that we can see are based on different wavelengths of light. The human eye can detect and differentiate wavelengths in three bands (red, green, and blue) covering the range from 450 to 650 nanometers, but we cannot see light from the hundreds of other bands of light that exist outside of that range. There is a technology called hyperspectral imaging that can give an enhanced view of what is going on in the world around us. There are specialized cameras that separate up to 300 bands of light with prisms and then digitize the energy they are detecting on a wavelength-specific basis. These cameras have a huge range of potential applications.
The human eye can only see three primary color bands (red, green, blue). There are hundreds of more bands and with enhanced hyperspectral camera technology there are many valuable applications.
Older women heal bone fractures slower than men. Now a team has found that a single, localized delivery of estrogen to a fracture can speed up healing in postmenopausal mice. The findings could have implications for the way fractures in women are treated in the future.
Over 250,000 hip fractures occur each year in adults aged 65 or older in the U.S., three-quarters of which are female. Within a year, between 15 and 36% of hip fracture patients will die. While staggering, the gender gap is unsurprising given that more women than men suffer from osteoporosis, a disease that weakens the bones. And yet, only recently has the scientific community shifted their focus to understanding this difference.
“The majority of stem cell research is done on male animals. There’s very little research that has actually been done on females,” said Wu Tsai Alliance member Charles Chan, Ph.D., an assistant professor of surgery at Stanford University and co-senior author of the paper published Oct. 30 in Nature Communications. “The research is long overdue, especially the question of why women heal differently from men.”
Are alien civilizations likely to be younger or older than us in age? A basic question that seems insurmountable until we start detecting them. But even before that, we can use some logical deduction using lifetime distribution statistics to determine the most plausible answer to this question. Join us today for an explanation of our new research paper on this topic.

Germany says China is operating two illegal ‘police stations’ on its territory. These set-ups don’t have a fixed office, and are run by private individuals from the Chinese diaspora. The aim is to collect information on Chinese dissidents and citizens in exile and pass that on to Beijing. Its a pattern that’s come to light across the world. An earlier report by Madrid based NGO Safeguard Defenders claimed there were more than a hundred such ‘police stations’ in at least 53 countries. Most exist illegally and aim to monitor, coerce and in some instances repatriate, those Beijing considers criminal or anti-China.
At number 20 on IE’s 22 best innovations of 2022, we take a look back at this intimate invention.
Can you imagine kissing someone you love long distance? As sci-fi films have showcased this is one innovation that is desired by many. In May of 2022, Carnegie Mellon University’s Future Interfaces Group released a new invention that consists of a headset that can achieve just that.
This impressive achievement was done using ultrasonic transducers.

More specifically, the headset recreates the sense of touch on a wearer’s face — for example, a kiss on the mouth — without adding any parts that actually cover that area.
