What’s the ultimate reason we die? In this video, science writer Michael Shermer discusses the universal laws that preside over why stars fade out — and we do, too.
It might be tempting to not take your contacts off before bed, however, graphic images of an eye ulcer that formed when someone slept with their soft lenses might make you think twice about it.
Patrick Vollmer, an eye doctor who works at the Vita Eye Clinic in Shelby, North Carolina, posted stomach-churning photos of a patient he recently treated, who had a cultured pseudomonas ulcer from wearing their contacts when they slept, The New York Post reported. Vollmer shared the graphic images on Facebook and urged people to think about the harmful consequences of sleeping with contacts.
“Astronauts at the international space station expecting a delivery on Monday that private company SpaceX launched a cargo capsule loaded with supplies from Cape Canaveral early this morning the shipment. The company’s seventeenth to the orbiting outpost includes a new instrument to measure CO two in the atmosphere. Then peers Rebecca hersher reports it will be attached. To the space station measuring how much carbon dioxide is. In the atmosphere is really fundamental for understanding how the climate is changing. But it’s difficult for one thing. The amount of co two varies each day and each season and each year and measurements have to be both global and extremely precise. The new instrument can do both. It’s designed to scan the earth measuring not only how much co two is entering the atmosphere. But how much of the greenhouse gas is being absorbed by plants and oceans the instrument is called the orbiting carbon observatory three two other versions. Have previously been launched. Overall. NASA says the ability to measure co two from space has already helped scientists better understand our climate and predict how it will change”

Space technologies will one day take us to asteroids, Mars and back to the moon, and the impact of these missions will be felt back on Earth, says George Whitesides, Chief Executive Officer at Virgin Galactic and co-chair of the Global Future Council on Space Technologies. In this interview, he explains how the latest developments in space technologies will help bring about revolutions in wifi access, travel and beyond. science space science cool science space and science universe space science.
What is the state of space technology today?
We are at an exciting moment. What we see are several converging trends that will change how we approach space technologies, at a rate of innovation that we haven’t seen in a long time. science space science cool science space and science universe space science.

Equipped with only dining hall spoons, the clothes on their backs, and pure archaeological curiosity, undergraduates at Cambridge’s Newnham College in 1939 were given a crash course in field work when their professor, Dorothy Garrod, led them through the excavation of skeletal remains that had been unearthed on campus as a result of air-raid shelter preparations.
“[The dig was] definitely not up to today’s PPE [personal protective equipment] standards for sure,” Sam Leggett, a current doctoral student in archaeology at Newnham College, wrote in an email to Gizmodo. As rudimentary as the excavation may have been, he said, “I’ve recently been involved with radiocarbon dating these skeletons, and have undertaken stable isotope analysis on their teeth as part of my PhD, so Professor Garrod’s legacy definitely still lives on!”
Organ preservation could be an effective therapy for end-stage organ failure, says Sebastian Giwa, the Chairman and CEO of the Organ Preservation Alliance, a non-profit organization focused on advancing organ preservation. Giwa discusses the challenges and strategies related to organ preservation.
New Mexico additive manufacturing software developer Sigma Labs, has obtained third-party validation of its PrintRite3D platform in a study by U.S. defense agency DARPA.
The study discusses the validation process involved in producing complex metal parts of consistent quality. It was sponsored by DARPA’s Open Manufacturing Program and conducted in conjunction with aircraft engine manufacturer Honeywell Aerospace, which has been collaborating with Sigma labs since 2014.
As an agency of the United States Department of Defense (DoD), DARPA is responsible for the development of emerging technologies for use by the military. In line with this goal, it created the Open Manufacturing program to ‘lower the cost and speed the delivery of high-quality manufactured goods with predictable performance.’
