NASA ‘Cribs’: Tour an Astronaut Habitat for Mock Space Missions (Video)

Posted by in categories: food, habitats, space

Ever wonder how astronauts will live on other worlds? Welcome to the Human Exploration Research Analog, or HERA, a habitat at NASA’s Johnson Space Center in Houston built to simulate the isolation of missions to deep space. You can take a tour of the HERA habitat with NASA interns in this new video in the style of the MTV series “Cribs.”

“HERA is a unique three-story habitat designed to serve as an analog for isolation, confinement, and remote conditions in exploration scenarios,” NASA officials explained in a video description. “This video gives a tour of where crew members live, work, sleep, and eat during the analog missions.”

How sugar affects the brain?

Posted by in categories: food, neuroscience

When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. This activation of your reward system is not unlike how bodies process addictive substances such as alcohol or nicotine — an overload of sugar spikes dopamine levels and leaves you craving more.

With this video prepared by TED-Ed, Nicole Avena explains why sweets and treats should be enjoyed in moderation.

Deadly heat waves projected in the densely populated agricultural regions of South Asia

Posted by in categories: biotech/medical, business, food, neuroscience, sustainability

The risk associated with any climate change impact reflects intensity of natural hazard and level of human vulnerability. Previous work has shown that a wet-bulb temperature of 35°C can be considered an upper limit on human survivability. On the basis of an ensemble of high-resolution climate change simulations. we project that extremes of wet-bulb temperature in South Asia are likely to approach and. in a few locations. exceed this critical threshold by the late 21st century under the business-as-usual scenario of future greenhouse gas emissions. The most intense hazard from extreme future heat waves is concentrated around densely populated agricultural regions of the Ganges and Indus river basins. Climate change. without mitigation. presents a serious and unique risk in South Asia. a region inhabited by about one-fifth of the global human population. due to an unprecedented combination of severe natural hazard and acute vulnerability.

The risk of human illness and mortality increases in hot and humid weather associated with heat waves. Sherwood and Huber proposed the concept of a human survivability threshold based on wet-bulb temperature (TW). TW is defined as the temperature that an air parcel would attain if cooled at constant pressure by evaporating water within it until saturation. It is a combined measure of temperature [that is. dry-bulb temperature (T)] and humidity (Q) that is always less than or equal to T. High values of TW imply hot and humid conditions and vice versa. The increase in TW reduces the differential between human body skin temperature and the inner temperature of the human body. which reduces the human body’s ability to cool itself. Because normal human body temperature is maintained within a very narrow limit of ±1°C. disruption of the body’s ability to regulate temperature can immediately impair physical and cognitive functions.

More Colorful Vegetables and Fruits Can Protect You From Alzheimer’s and Dementia: Neal Barnard

Posted by in categories: biotech/medical, food, health, robotics/AI

Dr. Neal Barnard says: “More colorful vegetables and fruits, a 40-minute brisk walk, vitamin E and less dairy products, cheese, and milk can protect you from alzheimer’s and dementia.”

Dr. Neal Barnard has led numerous research studies investigating the effects of diet on diabetes, body weight, and chronic pain, including a groundbreaking study of dietary interventions in type 2 diabetes, funded by the National Institutes of Health. Dr. Barnard has authored over 70 scientific publications as well as 17 books.

Building Artificial Bile Ducts to Treat Childhood Liver Disease

Posted by in categories: biotech/medical, food

Researchers in Cambridge have created a new approach for creating and transplanting artificial bile ducts with the aim of treating liver disease in children and reducing the need for transplants.

The research, published in the journal Nature Medicine, shows how the researchers grew 3D cell structures and transplanted them into mice[1]. These structures then developed into functional bile ducts.

The bile ducts are long, tubular structures that carry bile secreted by the liver which is critical for helping us to digest our food. When these ducts do not function properly, such as in childhood diseases like biliary atresia, it can lead to a damaging buildup of bile in the liver.

Scientists Just Made Food From Electricity

Posted by in categories: food, solar power, sustainability

A batch of single-cell protein has been produced by using electricity and carbon dioxide in a joint study by the Lappeenranta University of Technology (LUT) and VTT Technical Research Centre of Finland. Protein produced in this way can be further developed for use as food and animal feed. The method releases food production from restrictions related to the environment. The protein can be produced anywhere renewable energy, such as solar energy, is available.” In practice, all the raw materials are available from the air. In the future, the technology can be transported to, for instance, deserts and other areas facing famine.

Floating City Project Wants To Make An ‘Unregulated’ Hub Of Scientific Research

Posted by in categories: biotech/medical, economics, engineering, food, governance, law, nanotechnology, robotics/AI, sustainability

In the hopes of rising above the laws and regulations of terrestrial nations, a group of Silicon Valley millionaires has bold plans to build a floating city in Tahiti, French Polynesia. It sounds like the start of a sci-fi dystopia (in fact, this is the basic premise behind the video game Bioshock), but the brains behind the project say their techno-libertarian community could become a paradise for technological entrepreneurship and scientific innovation.

The Seasteading Institute was set up in 2008 by billionaire PayPal founder Peter Thiel and software engineer, poker player, and political economic theorist Patri Friedman. Both ardent libertarians, their wide-eyed mission is to “establish permanent, autonomous ocean communities to enable experimentation and innovation with diverse social, political, and legal systems.”

“Seasteading will create unique opportunities for aquaculture, vertical farming, and scientific and engineering research into ecology, wave energy, medicine, nanotechnology, computer science, marine structures, biofuels, etc,” their website reads.
