3D ‘bioprinting’ used to create nose cartilage

A team of University of Alberta researchers has discovered a way to use 3-D bioprinting technology to create custom-shaped cartilage for use in surgical procedures. The work aims to make it easier for surgeons to safely restore the features of... Continue Reading →

NASA’s Ingenuity Mars Helicopter Logs Second Successful Flight

NASA’s Ingenuity helicopter successfully completed its second Mars flight on April 22 – the 18th sol, or Martian day, of its experimental flight test window. Lasting 51.9 seconds, the flight added several new challenges to the first, which took place on... Continue Reading →

Researchers uncover how cells control the physical state of embryonic tissues

In the earliest stage of life, animals undergo some of their most spectacular physical transformations. Once merely blobs of dividing cells, they begin to rearrange themselves into their more characteristic forms, be they fish, birds or humans. Understanding how cells... Continue Reading →

Alnitak and the Flame Nebula

What lights up the Flame Nebula? Fifteen hundred light years away towards the constellation of Orion lies a nebula which, from its glow and dark dust lanes, appears, on the left, like a billowing fire. But fire, the rapid acquisition of oxygen, is not what makes this Flame glow. Rather... Continue Reading →

‘Zombie’ genes? Research shows some genes come to life in the brain after death

In the hours after we die, certain cells in the human brain are still active. Some cells even increase their activity and grow to gargantuan proportions, according to new research from the University of Illinois Chicago. In a newly published... Continue Reading →

Adenovirus- based vaccines Vs. mRNA vaccines

Getting CubeSats moving

ESA’s M-Argo mission will be the first CubeSat to traverse interplanetary space under its own power. Due to launch in 2024-5, the suitcase-sized spacecraft will travel to a near-Earth asteroid, up to 150 million km away. CubeSats are small, cheap satellites assembled... Continue Reading →

Algorithm Designs Soft Robots That Sense

There are some tasks that traditional robots — the rigid and metallic kind — simply aren’t cut out for. Soft-bodied robots, on the other hand, may be able to interact with people more safely or slip into tight spaces with... Continue Reading →

Veil Nebula: Wisps of an Exploded Star

Wisps like this are all that remain visible of a Milky Way star. About 7,000 years ago that star exploded in a supernova leaving the Veil Nebula. At the time, the expanding cloud was likely as bright as a crescent Moon, remaining visible for weeks to... Continue Reading →
