Covering Yourself in Aerogel and Jumping Into a Pool Looks So Surreal

Aerogel has extraordinary properties but it can be tough to work with. This video by Veritasium looks at modifying aerogels to take advantage of their unique characteristics. Aerogel’s extraordinary properties are due in large part to its structure. Aerogel is a solid but on the nanoscale it has a mesh or sponge-like structure. The struts of this structure are nanoscale, as are the pores at around 20nm across. This makes silica aerogel incredibly light (it was once the lightest solid but has now been superseded by graphene aerogel), transparent and…

Can a face mask protect me from coronavirus? Covid-19 myths busted

The truth about how you can catch coronavirus, how much more elderly people are at risk and what you can do to avoid infection Claim: Face masks dont work Wearing a face mask is certainly not an iron-clad guarantee that you wont get sick viruses can also transmit through the eyes and tiny viral particles, known as aerosols, can penetrate masks. However, masks are effective at capturing droplets, which is a main transmission route of coronavirus, and some studies have estimated a roughly fivefold protection versus no barrier alone (although…

Surreal Video Captures Spanish Resort Town Covered in Sea Foam

High waves and flooding cause sea foam to cover the streets of Tossa De Mar in Spain. The seaside resort town is located near Girona in Catalonia and the rare phenomenon has not occurred in years. Sea foam forms when the ocean churns up high concentrations of ‘organic matter’, and the strong and steady winds made clean-up efforts only worse.

Bionic neurons could enable implants to restore failing brain circuits

Scientists say creation could be used to circumvent nerve damage and help paralysed people regain movement Scientists have created artificial neurons that could potentially be implanted into patients to overcome paralysis, restore failing brain circuits, and even connect their minds to machines. The bionic neurons can receive electrical signals from healthy nerve cells, and process them in a natural way, before sending fresh signals on to other neurons, or to muscles and organs elsewhere in the body. One of the first applications may be a treatment for a form of…

Observation of the Development of a Chick Embryo by Shell-Less Hatching

In this astonishing video by the Mihama Veterinary Clinic in Fukui, Japan, we observe the development of a chick embryo by shell-less hatching method. This demonstration is practiced mainly based on the scientific article written by Tahara et. al. The eggs sold in-store are usually unfertilized egg and never develop into chicks, so you don’t have to worry about an eating embryo or baby chick. However, fertilized egg may be sold in organic or natural health stores, family poultry farms, etc. where chicks can grow just same as a normal…

The Hubble constant: a mystery that keeps getting bigger

Scientists have found a discrepancy in estimates for the rate of expansion of the universe. Why is this and what does it mean? Astronomers have reached a fundamental impasse in their understanding of the universe: they cannot agree how fast it is flying apart. And unless a reasonable explanation can be found for their differing estimates, they may be forced to completely rethink their ideas about time and space. Only new physics can now account for the cosmic conundrum they have uncovered, many believe. Five years ago, no one in…

Were One Step Closer to Making Harry Potters Invisibility Cloak a Reality

Harry Potter’s ‘invisibility cloak’ appears closer to reality as Canadian camouflage manufacturer Hyperstealth Biotechnology has applied for patents on its ‘Quantum Stealth’ material. The ‘inexpensive and paper-thin’ technology works by bending light around a target to either alter its position or make it vanish altogether, leaving only the background visible. It is touted to be able to obscure the positions of heavy artillery, ground troops or even entire buildings from certain viewpoints.
