New bio-ink allows for direct

New bio-ink allows for direct 3D printing tissues within the body

Although we're hearing more about the prospect of 3D-printed replacement body parts, those parts need to be implanted via relatively large incisions. That may not always be the case, however, thanks to a new "bio-ink" that could allow parts to be printed within the body. And while bio-inks are Read More...

Beetle that lives near volcano

Beetle that lives near volcanos inspires new eco-friendly cooling material

Heating and cooling systems are some of the biggest consumers of energy, so finding ways to passively cool buildings and electronics could be a huge saver of money and the environment. Now, thanks to a beetle that likes to hang out in some of the hottest places on Earth, scientists have Read More...

Anyone out there? Our galaxy may host more alien life than we thought

For astronauts and E.T. fans alike, the big question has always been, is there alien life out there? Now, science may be able to offer an answer to that question. Although nobody has received communication from any alien civilizations, researchers estimate that there are 36 viable sites for life in Read More...

Battery supplier claims new design can power a vehicle for 1.2 million miles

Electric vehicles had their biggest year yet in 2019, with their total market share amounting to 2.5 percent at the end of the year. While it may seem like a small percentage, it represents significant growth for the electric vehicle industry. To speed up this transition towards cleaner Read More...

Infrastructure changes to sust

Infrastructure changes to sustain falling emissions past the pandemic

Throughout the pandemic, we’ve covered stories of reduced emissions and environmental recovery, but now we face the daunting question of how to maintain lowered emissions as we reopen the economy. In most cities, transportation is the first or second-largest source of greenhouse gas emissions and Read More...

Collapsed stars again validate

Collapsed stars again validate Einstein’s theory of relativity

Albert Einstein died in 1955, but scientists have continued to explore and validate his findings long after his death. Most recently, scientists have looked at collapsed stars for further confirmation of his theory of relativity. Looking at a trio of two white dwarf stars and a collapsed neutron Read More...

New bionic eye could restore sight and even offer night vision

As we’ve talked about on The Optimist Daily, prosthesis technology has come a long way in recent years, but the human eye has always been difficult to replicate. Now, scientists have designed a prototype for the first 3D artificial bionic eye, which could let users see better than with the real Read More...

Scientists harness renewable e

Scientists harness renewable energy using water vapour in the air

Renewables are about to welcome a new member into the family of clean energy sources, thanks to researchers in Israel who have managed to generate a voltage using water vapor in the atmosphere. The concept of humidity as a source of energy is based on a recent study in the journal Nature that Read More...
