A team of scientists at Freie Universität Berlin has developed an artificial intelligence (AI) method for calculating the ground state of the Schrödinger equation in quantum chemistry. The goal of quantum chemistry is to predict chemical and physical properties of molecules based solely on the arrangement of their atoms in space, avoiding the need for resource-intensive and time-consuming laboratory experiments. In principle, this can be achieved by solving the Schrödinger equation, but in practice this is extremely difficult.
Up to now, it has been impossible to find an exact solution for arbitrary molecules that can be efficiently computed. But the team at Freie Universität has developed a deep learning method that can achieve an unprecedented combination of accuracy and computational efficiency. AI has transformed many technological and scientific areas, from computer vision to materials science. “We believe that our approach may significantly impact the future of quantum chemistry,” says Professor Frank Noé, who led the team effort. The results were published in the reputed journal Nature Chemistry.
Central to both quantum chemistry and the Schrödinger equation is the wave function —a mathematical object that completely specifies the behavior of the electrons in a molecule. The wave function is a high-dimensional entity, and it is therefore extremely difficult to capture all the nuances that encode how the individual electrons affect each other. Many methods of quantum chemistry in fact give up on expressing the wave function altogether, instead attempting only to determine the energy of a given molecule. This however requires approximations to be made, limiting the prediction quality of such methods.
If you’ve ever heard someone refer to the idea of “working in space,” you’d be forgiven for thinking they were describing a science-fiction plot. But the number of humans actively working beyond Earth’s atmosphere — and living significant chunks of their lives there, too — is about to start growing at a potentially exponential rate. Given how small that population is now, the growth might look slow at first — but it’s happening soon, and plans are in place to help it start ramping up quickly.
The main company leading those plans in the near-term is Axiom Space, a private space station service provider, and eventual operator. Axiom is founded and led by people with International Space Station experience and expertise, and the company already operates R&D missions on behalf of private clients on the ISS with the help of NASA astronauts. It’s planning to begin shuttling entire flights of private astronauts to the station starting in 2021, and it’s also building a new, commercial space station to ultimately replace the ISS on orbit once that one is decommissioned.
Axiom Space’s Chief Business Office Amir Blachman joined us at TC Sessions: Space last week on a panel that included NASA Chief of Exploration and Mission Planning Nujoud Merancy, Sierra Nevada Corporation senior vice president and former astronaut Janet Kavandi, as well as Space Exploration Architecture (SEArch+) co-founder Melodie Yashar. The panel was focused on how public and private entities are preparing for a (relatively near) future in which humans spend more time off Earth — and further away from it, too.
Members of the US Space Force will be known as “guardians”, it was announced on the military service’s first birthday.
US Vice President Mike Pence said: It is my honour, on behalf of the president of the United States, to announce that henceforth the men and women of the United States Space Force will be known as guardians.
Mike Pence says soldiers, sailors, airmen, Marines and guardians will be defending our nation for generations to come.
If you thought you knew all of the mid-drive motors in the e-bike world, think again. The French company Valeo has just unveiled a radical new type of mid-drive electric motor that adds a built-in automatic transmission.
Automatic transmissions alone aren’t unique in the e-bike space.
We’ve tested several models that feature mid-drive motors paired with automatic transmissions.
MANILA, Philippines — A Filipino startup is recognized globally in developing a dengue hotspot prediction system using satellite and climate data in the 2020 Group on Earth Observations Sustainable Development Goals (GEO SDG) Awards for the Sectoral category, For-Profit. The GEO SDG Awards recognize the productivity, ingenuity, proficiency, novelty, and exemplary communications of results and experiences in the use of Earth observations to support sustainable development.
CirroLytix Research Services was formed to create social impact through big data. Through the application of machine learning, data engineering, remote sensing, and social listening, the Philippines-based data analytics firm hopes to help governments, researchers, non-government organizations (NGO), and social enterprises achieve positive change. The Advanced Early Dengue Prediction and Exploration Service (Project AEDES) is one of the CirroLytix’s flagship projects developed during the 2019 National Aeronautics and Space Administration’s (NASA) International Space Apps Challenge. It combines digital, climate, and remote sensing to nowcast dengue trends and detect mosquito habitats to help pre-empt cases of dengue. Project AEDES process leverages normalized difference vegetation index (NDVI), Fraction of absorbed photosynthetically active radiation (FAPAR), and normalized difference water index (NDWI) readings from Landsat and Sentinel-2 to estimate still water areas on the ground, which is correlated with dengue case counts from national health centers.

Dominic Vincent “Doc” Ligot, co-founder and chief technology officer of CirroLytix, describes Project AEDES as an “early detection of panics from online searches, anticipating case counts from environment readings, but most importantly pinpointing hotspots from mosquito habitat detection.”
The Pinoy-made dengue mapper tool won the annual international hackathon of NASA globally in the best use of data, the solution that best makes space data accessible, or leverages it to a unique application. Aside from winning last year, CirroLytix also developed an integrated public policy information portal measuring the impact of the coronavirus pandemic using Earth observation, in-country economic and human mobility data, and global infection case counts, thus winning again in the Space Apps COVID-19 Challenge for the same category in the best use of data. Named G.I.D.E.O.N. (Global Impact Detection from Emitted Light, Onset of COVID-19, and Nitrogen Dioxide), this dashboard for policy makers and economic planners shows the impact of COVID-19 on various countries and effects on the economy and environment.
With these achievements, Cirrolytix is recognized in their remarkable efforts to utilize Earth observation data to predict dengue fever cases in the Philippines in order to improve public health.
“I am glad that the GEO SDG Awards Panel has selected CirroLytix for an award, recognizing the importance of this work in developing an EO-integrated dengue case predictor mapping system,” according to Dr. Argyro Kavvada, lead for Sustainable Development Goals of the Earth Science Division, NASA’s Science Mission Directorate and executive secretary of the international Earth Observations for the Sustainable Development Goals (EO4SDG).
“These awards really could stand as an inspiration to all of us about what can be done, and what needs to be done to ensure that Earth-observations contribute to make our world a better, and more sustainable place,” said Lawrence Friedl director of the Applied Sciences Program of the Earth Science Division, NASA’s Science Mission Directorate and co-chair of EO4SDG.

The Undersecretary for Competitiveness and Innovation of the Department of Trade and Industry (DTI) Dr. Rafaelita “Fita” M. Aldaba heartfeltly congratulates CirroLytix. “It’s indeed a blessing amid this pandemic and economic crisis that we are currently faced with,” she said.
The award-winning startup continues to update the AEDES framework to include socio-economic risk mapping to turn it into a health and environmental policy tool. Aside from dengue, the company also supports COVID-19 modeling and response initiatives with the public health sector. CirroLytix’s current involvements include public health, human rights, fighting disinformation, education and food security.
The Space Apps lead organizer in the Philippines Michael Lance M. Domagas appeals support for these Filipino winners. “How many times should these Filipino innovators and achievers need to win before being recognized and appreciated by our own country? To be recognized by not just one, but five space agencies is something has not yet been achieved by Filipinos, how much more of a multitude of countries and nations supporting the sustainable development goals of the United Nations?” He added that “The dengue epidemic and the COVID-19 is a real threat to the Philippine society right now, endangering health, well-being, livelihood, and most especially businesses and the national economy. If we could only learn how to give value to science, technology, mathematics, and engineering (STEM), the possibilities are endless. Our Filipino winners of Space Apps and GEO SDG Awards have taught us on how these space technologies greatly help in addressing epidemics and economic impact of COVID-19, its time to give them recognition and respect because they are Filipinos like us.” Winners shall be invited to visit NASA once travel is deemed safe, but unfortunately, travel, meals and incidental expenses, and accommodation expenses are not provided.

NASA’s Lunar Reconnaissance Orbiter captured an image of China’s Chang’e 5 lander on the moon just hours after its historic landing.
The Chang’e 5 lander set down on the lunar surface last Tuesday, Dec. 1. Thanks to China’s prompt release of the stunning Chang’e 5 landing video, the Lunar Reconnaissance Orbiter Camera (LROC) team were able to locate the roughly 4-ton spacecraft in Oceanus Procellarum, the “Ocean of Storms,” and prepare for when LRO would pass overhead the next day.
On Dec. 21, humans can witness something not seen in nearly 800 years.
That’s right, during the upcoming winter solstice, Jupiter and Saturn will line up to create what is known as the “Christmas Star” or “Star of Bethlehem.”
These two planets haven’t appeared this (relatively) close together from Earth’s vantage point since the Middle Ages.
