Scientists have discovered yet another life-giving treatment for disease using adult stem cells, while the number of substantial medical breakthroughs from life-taking embryonic stem cell research remains essentially zero.

Neuromyelitis optica (NMO), also known as Devic’s disease, causes the immune system to react against the body’s own cells in the central nervous system, particularly the eyes and spinal cord. Those who contract the disease usually lose their eyesight and ability to walk within five years.

Stem cells are the body’s cell factories, aiding in growth and damage repair. In a study published Oct. 2 in Neurology, researchers from Northwestern University and the Mayo Clinic tested a new adult stem cell treatment on 12 people with NMO. They drew hematopoietic stem cells (also known as blood stem cells) from the patient’s bone marrow or blood. Then they used chemotherapy to shut down the patient’s malfunctioning immune system. When they transplanted the stem cells back into the patient’s body, the immune system restarted from scratch.

Scientists at Harvard have created a texture in meat grown in a lab close to the actual animal meat we’re used to. Would you eat it?

Human meat consumption is bad for the planet—livestock raised for food makes up for approximately 14–18% of our greenhouse gas emissions, and the land requirements to grow their food is responsible for nearly 80% of all deforestation in the Amazon.

80%!

So scientists have been working to create a realistic imitation for animal meat in a lab, and with a recent breakthrough researchers from Harvard have come one step closer to making lab-grown meat taste and feel like the real deal.

How?

Gelatin.

Could a stingray-shaped spacecraft get to the dark side of Venus by flapping its wings?

Researchers at the University of Buffalo (UB) are designing a spacecraft shaped like a stingray that could explore Venus in ways never before possible. The craft, designed as part of the Bio-inspired Ray for Extreme Environments and Zonal Explorations (BREEZE) project, is one of 12 selected by NASA for the agency’s Innovative Advanced Concepts (NIAC) program, which supports new, innovative technologies.

There’s no telling what you can do when you put your mind to it. Take Richard Hull, he built a small-scale fusion reactor—in a shed, in his backyard. A retired electronics engineer, Hull took a special interest in nuclear fusion. He lives in Lakeside, Virginia, with his cats and likes to pass on his knowledge and collaborate with others on projects. So he invites amateur scientists from all over the United States to meet at his home once a year to check out his reactor and share their inventions.

While many futures are generalists, there is a need for foresight professionals centered on specific fields, as well. Perhaps no area is more in need of innovative outlooks for the future than healthcare. With rising costs, aging populations and personnel shortages, the challenges are many. But so are the opportunities to employ emerging technologies. In the first part of a two part series, host Mark Sackler discusses these challenge with two nursing Ph.D.’s, Oriana Beaudet and Dan Pesut. Part One addresses the need for foresight both in nursing specifically and healthcare in general, as well as the global challenges of an aging population. Part two will drill down to individual ssues, including automation, robotics and artificial intelligence as caregiving tools for the future.

The televised gala, broadcast on the National Geographic Channel as well as YouTube and China’s Tencent, whose founder Ma Huateng is also a sponsor, played heavily on a theme that’s become somewhat tarnished in Silicon Valley in recent years—that scientific and technological progress will solve humanity’s biggest problems. For the past two years, Facebook and Google have both been battered by lawmakers and the public for how they’ve failed to eliminate the spread of fake news, conspiracy theories (sometimes about science) and content that connects violent extremists. Both Zuckerberg and Pichai have also countered rising complaints from the tech giants’ workforces.

Some of the top scientists who accepted Breakthrough Prize awards used the nationally broadcast ceremony to decry the spread of misinformation, problems that continue to dog the tech giants whose leaders, including Facebook CEO Mark Zuckerberg and Google CEO Sundar Pichai, celebrated at the glitzy Silicon Valley gala Sunday evening.

“Science is a rock of truth in a sea of fake news,” said physicist Peter van Nieuwenhuizen, who with collaborators Sergio Ferrara and Daniel Freedman accepted an award Sunday evening for their work around the theory of supergravity.

David Julius, a University of California at San Francisco physiology professor who won a $3 million award for research into the capsaicin found in chili peppers and pain relief, noted “we live in a time when technology and so many other resources make so much possible. ”
