A gene is a segment of DNA that contains a set of instructions to make molecules that organisms need to survive. In a process called gene expression, these instructions are converted into some sort of product. And the product usually is either a protein or functional RNA. So what is gene expression? And, how do genes express themselves?
You certainly don’t want to miss this. Watch Morgan Freeman, Brian Cox, Carl Sagan and Sir David Attenborough calmly explaining our universe’s beautiful journey since the Big Bang - in this stunning 10 minute timelapse video.
Engineers at University of Tokyo have created tiny lights that can levitate using ultrasonic waves. Named Luciola for its resemblance to the firefly, the particle weighs 16.2 mg, has a diameter of 3.5 mm, and glows red – bright enough to illuminate text.
Without salt, your favourite foods such as french fries, potato chips, and chocolate chip cookies would all taste bland. And that’s because salt has lots of effects on flavor perception than just making things more salty. Many say a spoonful of sugar helps the medicine go down, but a pinch of salt, in fact, does the work better. How is that? And why does salt make food taste better?
Light is made of individual photons, and these particles do not usually interact with each other. But a team of physicists from MIT and Harvard have successfully made three photons interact to create a new form of light - a breakthrough that could open a path toward using photons in quantum computing.
Researchers have developed an electronic skin that can heal itself - and is fully recyclable. The e-skin is a thin, translucent material with sensors embedded to mimic function and mechanical properties of human skin such as sensing pressure temperature, humidity and air flow.
Neuroscientists at University of California have identified 'anxiety cells' in the brain’s hippocampus. The finding, so far demonstrated with mice, could lead to better treatments for anxiety disorders in humans because the cells probably exist in humans, too, researchers say.
A study at Virginia Tech has found that mosquitoes can rapidly learn and remember the smells of hosts. Delicious-smelling individuals are usually the preferred targets, but swatting at them or performing other defensive behaviours – can teach them to stay away, researchers say. "Unfortunately, there is no way of knowing exactly what attracts a mosquito … Continue reading Mosquitoes Target Delicious-Smelling Individuals – But Swatting Teaches Them To Stay Away (For Days)
The Sun is losing mass as it’s getting older. As a result, its gravitational pull is weakening and the orbits of all the planets in our solar system are expanding. To earthlings, the effect of broadening of Earth’s orbit will likely remain minuscule as it’s expanding at the rate of less than an inch a year.
