NASA has selected two missions, dubbed DAVINCI+ and VERITAS, to study the “lost habitable” world of Venus. Each mission will receive approximately $500 million for development and both are expected to launch between 2,028 and 2030.
It had long been thought there was no life on Venus, due to its extremely high temperatures. But late last year, scientists studying the planet’s atmosphere announced the surprising (and somewhat controversial) discovery of phosphine. On Earth, this chemical is produced primarily by living organisms.
The news sparked renewed interest in Earth’s “twin,” prompting NASA to plan state-of-the-art missions to look more closely at the planetary environment of Venus—which could hint at life-bearing conditions.
This work proves that stability of C60 is a geometrical property of the thermodynamics of the system: a significant methodological advance since a detailed treatment of the energetics may be avoidable. This approach may be fruitful, not only for fullerenes but also for general problems of molecular stability and in other applications of conformational chemistry. For the non-chiral C60, C384, and the weakly-chiral C28, C76 and C380 (of these, C380 and C384 are classed as “unspirallable”), Schlegel projections are used to show that these fullerenes can all be represented by pairs of spirals counter-propagating in anti-parallel (C2) symmetry. For C60, the high symmetry is used to construct an analytical approximation for the sphericaldouble-spirals, shown mathematically to be Maximum Entropy (MaxEnt) using the formalism of Quantitative Geometrical Thermodynamics (QGT). Therefore C60 is necessarily stable. This MaxEnt stability criterion is general, depending only on the geometry and not the kinematics of the system. The sense and degree of chirality for C76 and C380 is also quantified using a Shannon entropy-based fragmentation metric.
Laser mining would allow for a no explosive option and not need huge machines increasing output as well. Also lasers could make more precise cuts rather than blades which would never get dull.
The application of the “Graduated Optical Colimator” (GOC) for the mining industry consists of a one-kilowatt optical power fiber laser to selectively spall igneous geological formations containing narrow veins of precious metals.
Merger said the prototype addresses key issues like mining using less explosives, chemicals and waste.
“We’ve been working at this problem for five or six years now – and we’ve discovered that a lot of laboratory research has been done in the private sector and in the government sector,” Gary Mladjan, Merger Mines’ VP, engineering and technology told MINING.COM.
Engineers at the University of Pennsylvania have found a new way to build and package microbatteries that drastically improve energy and power density even at the smallest sizes. They developed a new kind of current collector and cathode that increases the fraction of materials that store energy while simultaneously serving as a protective shell. This reduces the need for non-conductive packaging that normally protects a battery’s sensitive internal chemicals.
It weighs the same as two grains of rice but has the energy density of a much larger, heavier battery.
A 21st Century Mystery School — “Creating New Paradigms In Wellness And Wisdom Never Seen Before, And Never More Needed Than Now” — Dr. Dennis McKenna, Founder, McKenna Academy of Natural Philosophy.
Dr. Dennis McKenna is an American ethnopharmacologist, research pharmacognosist, lecturer, author, and Founder of the McKenna Academy of Natural Philosophy (www.mckenna.academy).
Dr. McKenna is a founding board member and the director of ethnopharmacology at the Heffter Research Institute, a non-profit organization concerned with the investigation of the potential therapeutic uses of psychedelic medicines. He also serves on the Advisory Board of the American Botanical Council; as Founder and Executive Director for the Institute for Natural Products Research; as an Independent Research Consultant to the Phytomedicine and Nutraceutical Industry; was formerly on the Editorial Board of Phytomedicine, International Journal of Phytotherapy and Phytopharmacology; and is an adjunct professor in the Center for Spirituality and Healing at the University of Minnesota.
Dr. McKenna received his Master’s Degree in Botany from the University of Hawaii in 1,979 his Ph.D. in Botanical Sciences from the University of British Columbia in 1,984 and continued into post-doctoral research fellowships in the Laboratory of Clinical Pharmacology, National Institute of Mental Health (NIMH), and in the Department of Neurology, Stanford University School of Medicine.
Dr. McKenna’s research led to the development of natural products for the Aveda Corporation, as well as greater awareness of natural products and medicines. He has authored or co-authored over 50 peer-reviewed scientific papers and written multiple books, including “The Brotherhood of the Screaming Abyss: My Life with Terence McKenna”, co-author of “The Invisible Landscape” with his brother Terence, and co-author of a widely recognized reference work on herbal medicines, titled “Botanical Medicines: the Desk Reference for Major Herbal Supplements”.
Traditional rockets are marginal at launching things into orbit. Their chemical propellants do not carry enough energy (in the form of chemical bonds) to accelerate their own mass to orbit, let alone a tank and payload on top of that. As well as expelling propellant, traditional rockets also have to jettison parts (stages) as they ascend. The payload that is finally released into orbit is a tiny fraction of the rocket that lifts off from the ground.
Since 1,988 and formation of the Posthuman Movement, and articles by early adopters like Max Moore were a sign our message was being received — although I always argued on various Extropian & Transhuman bulletin boards & Yahoo groups &c that “Trans” was a redundant middle and we should move straight to Posthuman, now armed with the new MVT knowledge (also figures on the CDR). There will be a new edition of World Philosophy, the first this millennium, to coincided with various Posthuman University events later this year. Here is the text:
THE EXTROPIAN PRINCIPLES V. 2.01 August 7 1992.
Max More Executive Director, Extropy Institute.
1. BOUNDLESS EXPANSION — Seeking more intelligence, wisdom, and. personal power, an unlimited lifespan, and removal of natural, social. biological, and psychological limits to self-actualization and self-realization. Overcoming limits on our personal and social. progress and possibilities. Expansion into the universe and infinite existence.
2. SELF-TRANSFORMATION — A commitment to continual moral. intellectual, and physical self-improvement, using reason and critical. thinking, personal responsibility, and experimentation. Biological and. neurological augmentation.
3. INTELLIGENT TECHNOLOGY — Applying science and technology to. transcend “natural” limits imposed by our biological heritage and environment.
4. SPONTANEOUS ORDER — Promotion of decentralized, voluntaristic.
Researchers at CU Boulder have developed a platform which can quickly identify common mutations on the SARS-CoV-2 virus that allow it to escape antibodies and infect cells.
Published today in Cell Reports, the research marks a major step toward successfully developing a universal vaccine for not only COVID-19, but also potentially for influenza, HIV and other deadly global viruses.
“We’ve developed a predictive tool that can tell you ahead of time which antibodies are going to be effective against circulating strains of virus,” said lead author Timothy Whitehead, associate professor of chemical and biological engineering. “But the implications for this technology are more profound: If you can predict what the variants will be in a given season, you could get vaccinated to match the sequence that will occur and short-circuit this seasonal variation.”
Researchers have developed a platform which can quickly identify common mutations on the SARS-CoV-2 virus that allow it to escape antibodies and infect cells, which could inform the development of more effective booster vaccines and tailored antibody treatments for patients with COVID-19.
Researchers asked U.S. regulators to pull some sunscreens from the market, including brands such as Coppertone, Banana Boat and Neutrogena, saying they’ve found evidence of a potential carcinogen.
Scientists petitioned the Food and Drug Administration to remove from sale all sunscreens containing the active ingredient octocrylene. Products made with the chemical may contain benzophenone, a suspected carcinogen that also can interfere with key hormones and reproductive organs, according to a group led by Craig Downs, executive director of the nonprofit Haereticus Environmental Laboratory that studies risks to health and the environment.
