The new thermoelectric device can produce electricity at nighty by harnessing the dark, cold environment. In the initial proof of concept demonstration, it produced 25 milliwatts of energy per square meter, which is enough to power a small LED. ...
From classical antiquity to much of the early modern period — when there were no hard-written criminal laws — brutal tortures were a common method to serve punishments. During the middle ages, committing a crime wouldn’t have...
Researchers propose a new methodology to develop a periodic table for molecules with different types of symmetries. This new approach is strongly supported by many quantum mechanical calculations and various existing molecules. In 1869, a Russian...
The new ultra-black material absorbs more than 99.995% of incoming light from all angles. It is 10 times darker than Vantablack, the previous record holder for darkness. In 2014, scientists created the world’s darkest material capable of...
String theory says that indivisible subatomic particles are made of tiny little strings vibrating in a specific pattern. Each vibrational pattern corresponds to a different particles. Electron is nothing but a string vibrating in one pattern, and a...
The calculators we know today were first invented in the 1960s and the use of smartphones as calculators began in the 1990s. However, that does not mean that mathematical tools weren’t available a century ago. Several computing machines were...
Have you ever wondered who the most powerful Marvel characters are? As an MCU fan, I am sure you do. But to be frank it is a herculean task to answer. The list below ranks the most powerful comics characters based on their raw power and intellect...
Researchers analyze recorded cigarette sales and survey data in England between 2011 and 2018. They found that overall consumption of cigarette has declined by almost 1/4th during this period. Government has committed to making the United Kingdom...
Researchers investigate aspects of human aging in a small study. They found evidence that the biological age of a person can be reversed. The results seem promising and researchers will try to replicate them in an appropriately large follow-up study...
When it comes to high-speed trains, China Railway is in a class by itself. According to the Railway Gazette International, China has outstripped all its competitors with the fastest trains attaining start-to-stop averages well over 180 mph (300...
There is certainly no single genetic signature for determining same-sex sexual behavior. The conclusion is based on a large study that involved more than 493,000 people. Instead, there are a bunch of small genetic factors and environmental...
The new wood membrane can remove water contaminants using far less energy than commercially available membrane. Its thermal efficiency, water flux, sustainability, and scalability make it a perfect material for membrane distillation applications. ...
