This Man-Made Leaf Turns Water and Carbon Dioxide into Oxygen

This Man-Made Leaf Turns Water and Carbon Dioxide into Oxygen

If humanity hopes to realize its dreams of exploring the stars, we're going to need to find ways to recreate life on Earth aboard a spaceship. Simply stockpiling enough vital supplies isn't going to cut it, which is what led Julian Melchiorri, a student at the Royal College of Art, to create an artificial biological leaf ...

Study: California Could Run Entirely on Clean Energy by 2050

Study: California Could Run Entirely on Clean Energy by 2050

Stanford researchers have found that it’s “technically and economically” feasible to move California to an entirely clean energy system by 2050, using existing renewable sources like wind, water and sunlight. Published in Energy this week, the study concluded that the upfront capital costs would be more than offset by ...

NASA Releases Files So We Can 3D Print Space Stuff

NASA Releases Files So We Can 3D Print Space Stuff

It turns out that a decontextualised asteroid looks a lot like a Kipfler potato -- although we're not entirely sure that's the takeaway intended from a recent release by NASA. The space agency has made a whole bunch of files available for free so that you can 3D print your own space stuff. Included in the 21 objects ...

Google Wants to Figure Out What a Healthy Human Body Looks Like

Google Wants to Figure Out What a Healthy Human Body Looks Like

Google has embarked on what may be its most ambitious and difficult science project ever: a quest inside the human body. Called Baseline Study, the project will collect anonymous genetic and molecular information from 175 people—and later thousands more—to create what the company hopes will be the fullest picture of ...

Scientists Have Managed to Edit HIV Out of a Human Genome

Scientists Have Managed to Edit HIV Out of a Human Genome

As a retrovirus, HIV literally writes itself into the genome of the people it infects, which in turn programs a person's cells to make more viruses and thus remain infected. But a new human genome-editing technique has eradicated the virus from a human cell for the first time, in what could eventually function as an ...

Scientists Designed a Blood Test That Can Predict Alzheimer’s

Scientists Designed a Blood Test That Can Predict Alzheimer’s

Scientists have developed a new blood test that can predict who will develop Alzheimer's disease a year after having mild memory problems—and it could be in clinical use within two years. Researchers from King's College London have developed a test which identifies 10 proteins in blood that can predict who will develop ...

Researchers Can Now 3D Print Working Blood Vessels

Researchers Can Now 3D Print Working Blood Vessels

One of the biggest problems with printing human meat was the creation of blood vessels and ventricles. Making a solid mass of flesh was easy but adding a way to pump blood and other nutrients through the flesh was more difficult. Now researchers at the University of Sydney, Harvard, Stanford and MIT, have solved some of ...

Dentists Will Soon Have a Cavity Fix That’s Drill-Free

Dentists Will Soon Have a Cavity Fix That’s Drill-Free

Researchers from King's College London just announced a new approach to fixing cavities that requires no injections, no drills, and no pain. It's just a little blast of electric current that encourages the tooth to self-repair. And they say it'll be on the market in three years. The new technique sounds confusingly simple. ...

Scientists Developed WiFi Tech to Monitor Vital Signs Through a Wall

Scientists Developed WiFi Tech to Monitor Vital Signs Through a Wall

MIT's CSAIL lab has just taken its very cool but kinda creepy WiFi motion tracking to a new level: monitoring your vital signs from another room. Last we saw, the same researchers bounced low-powered WiFi signals (100x less than a home router) off of individuals to finely track their position behind a wall. The resulting ...

Scientists Have 3D Printed Blood Vessels

Scientists Have 3D Printed Blood Vessels

The tangled highway of blood vessels that twists and turns inside our bodies, delivering essential nutrients and disposing of hazardous waste to keep our organs working properly has been a conundrum for scientists trying to make artificial vessels from scratch. Now a team from Brigham and Women's Hospital (BWH) has made ...
