In 1960, American physicist Freeman Dyson proposed the idea that an extremely advanced—and power-hungry—alien civilization could, in theory, harness the majority of their host star’s energy by building a vast structure around it to absorb its radiation.
Scientists in the field of SETI (Search for Extraterrestrial Intelligence) have carried out a number of searches for such structures, known as Dyson spheres—which could be constructed using material harvested from dismantled planets—without uncovering any compelling evidence for them.
Now, in a paper published in The Astrophysical Journal, researchers from Uppsala University, Sweden, and Heidelberg University, Germany, have proposed a new way to look for Dyson spheres that may have some advantages over previous attempts.

Since its acquisition of ITA Matrix Software eight years ago, Google has been quietly rolling out new tools for travelers. Its progress has been even more notable over the past months and weeks as it began unveiling tools to help predict flight delays, plan trips, and manage itineraries — among other things.
These changes have some wondering: Is Google making a run at total domination in the travel space? If it is, there’s a strong case to be made for its potential to disrupt the travel and hospitality sector with a similar approach to Amazon’s run at retail, and more recently grocery.

Β-hydroxybutyrate seems to prevent senescence of vascular tissue.
According to a study by Georgia State University scientists, a molecule called β-hydroxybutyrate has anti-aging effects on the vascular system; more specifically, the molecule appears to prevent senescence of vascular cells by promoting cellular quiescence instead [1].
Study abstract
β-hydroxybutyrate (β-HB) elevation during fasting or caloric restriction is believed to induce anti-aging effects and alleviate aging-related neurodegeneration. However, whether β-HB alters the senescence pathway in vascular cells remains unknown. Here we report that β-HB promotes vascular cell quiescence, which significantly inhibits both stress-induced premature senescence and replicative senescence through p53-independent mechanisms. Further, we identify heterogeneous nuclear ribonucleoprotein A1 (hnRNP A1) as a direct binding target of β-HB binding to hnRNP A1 markedly enhances hnRNP A1 binding with Octamer-binding transcriptional factor Oct4 mRNA, which stabilizes Oct4 mRNA and Oct4 expression. Oct4 increases Lamin B1, a key factor against DNA damage-induced senescence. Finally, fasting and intraperitoneal injection of β-HB upregulate Oct4 and Lamin B1 in both vascular smooth muscle and endothelial cells in mice in vivo.
Several automakers interested in electric vehicles are turning to solid-state batteries for next-gen electric cars in the “post Li-ion era.”
Now a startup developing all solid-state batteries (ASSB) secured backing from several high-profile investors, including several automakers, as it claims a breakthrough for the technology that will enable better electric cars.
Solid Power is a Colorado-based startup that spun out of a battery research program at the University of Colorado Boulder.

$82 Trillion to convert a desert to land that could grow crops to help feed the world…is it worth it?
Researchers simulated the effects of around 79 terawatts of solar panels and 3 terawatts of wind turbines. Computer modeling looked at the effect of covering 20 percent of the largest desert on the planet in solar panels and installing three million wind turbines.
There would be 16X the rain in the aridest parts of the Sahara, and double that of the Sahel.
It should be noted that massive amounts of solar and wind power does directly alter the climate.
Utilizing new mobile application technology, researchers at The University of New Mexico found that medical cannabis provides immediate symptom relief across dozens of health symptoms with relatively minimal negative side effects.
In two recent studies titled, “Patient-Reported Symptom Relief Following Medical Cannabis Consumption,” and “Effectiveness of Raw, Natural Medical Cannabis Flower for Treating Insomnia under Naturalistic Conditions” published in the journals, Frontiers in Pharmacology and Medicines, respectively, UNM Department of Psychology Associate Professor Jacob Miguel Vigil and UNM Department of Economics Assistant Professor Sarah See Stith, document that patients experienced statistically and clinically significant therapeutic benefits when they used cannabis for symptoms ranging from chronic pain to insomnia.
These studies analyzed data collected with the Releaf App, developed by co-authors Franco Brockelman, Keenan Keeling and Branden Hall and currently, the largest repository of user-entered information on the consumption and effects of cannabis use in the United States with nearly 100,000 recorded user sessions.

When anti-waste campaigns backfire
Posted in food
Waste has become a serious problem in Western societies. About a third of the food produced in countries such as the [United Kingdom](http://foodawarecic.org.uk/stats-2/](http://foodawarecic.org.uk/stats-2/), Australia and the United States is wasted. About 40% is wasted by consumers, who buy too much, forget what’s in their refrigerator or cupboards, or throw away food that is past its expiration date yet perfectly edible.
Immense amounts of food is discarded by stores or restaurants because they weren’t sold before the official selling date, or for esthetic reasons – vegetables or fruit that have unusual shapes or are too big or too small, or food packages that are distorted… Waste also occurs with electronic goods that are discarded even though they work just fine and millions of tons of usable paper that are thrown away every year.

On any given day, Zoubaida Salman instructs a classroom of 15-year-olds at the Sur Baher Girls School in East Jerusalem, where she has served as the science teacher and Environment and Health Coordinator for the past 22 years. One of the most important lessons comes from their backyard: water is scarce and precious in this region.
Water shortages can lead to major sanitation issues at schools, so students have to play an active role in managing it. At Sur Baher, the most significant use of water is for flushing toilets, which stop working if there is not enough water. If the water runs out, school administrators must buy it from the city. In other regions, the schools even close because of water shortages.
A team of scientists with the NASA DEVELOP program is helping address these water shortages by collaborating with a nonprofit called Water Resources Action Project(WRAP). WRAP designs and constructs rainwater harvesting systems for schools in the Middle East to capture rainfall during the five-month rainy season for use later. Selecting a geographically promising area is time-consuming and tedious work though for the small, volunteer-based team. The NASA DEVELOP team is using satellite data to help WRAP more easily identify suitable locations for the rainwater harvesting systems.

Descartes once described the human body as a “fleshy machine” and today’s transhumanists would likely agree.
Philosopher Nick Bostrom writes that as we seek to peer farther into posthumanity our ability to concretely imagine what it might be like trails offend that the very essence of posthumanity is to be able to have thoughts and experiences that we cannot readily think or experience with our current capacities.
Today’s advances in science and technology will profoundly change what we understand as human. According to transhumanist philosophy humanity until this point has been a story of development for the survival and reproduction, but today thanks to advances in science we are entering a new phase where human beings are masters of their destiny. Therefore the Transhumanist movement envisions a future full of possibilities by broadening our potential as species by overcoming aging, cognitive shortcomings, involuntary suffering, and our confinement to planet Earth.
