Scientists at Newcastle University, in the United Kingdom, have 3D printed the world’s first real human corneas. This is unbelievable news since today, there is a significant shortage of corneas available for transplant. In the future, this printing technique could be used to ensure an unlimited supply of corneas.

The cornea is the outermost layer of the human eye and it has an important role in focusing vision. Statistics show that there are currently 10 million people worldwide requiring surgery to prevent corneal blindness as a result of diseases such as trachoma, an infectious eye disorder. On top of that, there are an additional 5 million people who suffer total blindness due to corneal scarring caused by burns, lacerations, abrasion or disease.

For the first time, researchers from the Universities of Bonn and Strasbourg have simulated the formation of galaxies in a universe without dark matter. To replicate this process on the computer, they have instead modified Newton’s laws of gravity. The galaxies that were created in the computer calculations are similar to those we actually see today. According to the scientists, their assumptions could solve many mysteries of modern cosmology. The results are published in the Astrophysical Journal.

Cosmologists today assume that matter was not distributed entirely evenly after the Big Bang. The denser places attracted more matter from their surroundings due to their stronger gravitational forces. Over the course of several billion years, these accumulations of gas eventually formed the galaxies we see today.

An important ingredient of this theory is the so-called dark matter. On the one hand, it is said to be responsible for the initial uneven distribution that led to the agglomeration of the gas clouds. It also explains some puzzling observations. For instance, stars in rotating galaxies often move so fast that they should actually be ejected. It appears that there is an additional source of gravity in the galaxies that prevents this—a kind of “star putty” that cannot be seen with telescopes: dark matter.

Data can be stolen from an air gapped personal computer just by using variations in screen brightness. Researchers at Ben-Gurion University wrote a paper on it.

As the team defines them, “Air-gapped computers are systems that are kept isolated from the Internet since they store or process sensitive information.”

Scientists from the United States to Australia are using new technology in an ambitious, multi-million-dollar drive to develop a vaccine in record time to tackle China’s coronavirus outbreak.

The new virus has spread rapidly since emerging late last year in China, killing more than 800 people in the mainland and infecting over 37,000. Cases have been reported in two dozen other countries.

Coming up with any vaccine typically takes years, and involves a lengthy process of testing on animals, clinical trials on humans and regulatory approvals.

I am amazed by just how far technology has come!

An image of her daughter was created with ‘virtual reality’ for a mother who lost her daughter in 2016 in South Korea. The moment the mother met her daughter left those in the studio in tears.

NASA Wallops Flight Facility is scheduled to launch a rocket tonight that will be visible to the DMV as it climbs into the sunset sky.

The facility hopes to launch the 13th Northrop Grumman resupply mission to the International Space Station (ISS) at 5:39 p.m. near sunset. The Cygnus cargo ship (spacecraft) is the S.S. Robert H. Lawrence, named for the first ever African American selected as an astronaut.

The launch and mission will be carried live by NASA.
