MANILA, Philippines — A dengue case forecasting system using space data made by Philippine developers won the 2019 National Aeronautics and Space Administration’s International Space Apps Challenge. Over 29,000 participating globally in 71 countries, this solution made it as one of the six winners in the best use of data, the solution that best makes space data accessible, or leverages it to a unique application.
Dengue fever is a viral, infectious tropical disease spread primarily by Aedes aegypti female mosquitoes. With 271,480 cases resulting in 1,107 deaths reported from January 1 to August 31, 2019 by the World Health Organization, Dominic Vincent D. Ligot, Mark Toledo, Frances Claire Tayco, and Jansen Dumaliang Lopez from CirroLytix developed a forecasting model of dengue cases using climate and digital data, and pinpointing possible hotspots from satellite data.
Correlating information from Sentinel-2 Copernicus and Landsat 8 satellites, climate data from the Philippine Atmospheric, Geophysical and Astronomical Services Administration of the Department of Science and Technology (DOST-PAGASA) and trends from Google search engines, potential dengue hotspots will be shown in a web interface.
Using satellite spectral bands like green, red, and near-infrared (NIR), indices like Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) and Normalized Difference Vegetation Index (NDVI) are calculated in identifying areas with green vegetation while Normalized Difference Water Index (NDWI) identifies areas with water. Combining these indices reveal potential areas of stagnant water capable of being breeding grounds for mosquitoes, extracted as coordinates through a free and open-source cross-platform desktop geographic information system QGIS.

“AEDES aims to improve public health response against dengue fever in the Philippines by pinpointing possible hotspots using Earth observations,” Dr. Argyro Kavvada of NASA Earth Science and Booz Allen Hamilton explained.
The DOST-Philippine Council for Industry, Energy and Emerging Technology Research and Development (DOST-PCIEERD) deputy executive director Engr. Raul C. Sabularse said that the winning solution “benefits the community especially those countries suffering from malaria and dengue, just like the Philippines. I think it has a global impact. This is the new science to know the potential areas where dengue might occur. It is a good app.”
“It is very relevant to the Philippines and other countries which usually having problems with dengue. The team was able to show that it’s not really difficult to have all the data you need and integrate all of them and make them accessible to everyone for them to be able to use it. It’s a working model,” according to Monchito B. Ibrahim, industry development committee chairman of the Analytics Association of the Philippines and former undersecretary of the Department of Information and Communications Technology.
The leader of the Space Apps global organizing team Dr. Paula S. Bontempi, acting deputy director of the Earth Science Mission, NASA’s Science Mission Directorate remembers the pitch of the winning team when she led the hackathon in Manila. “They were terrific. Well deserved!” she said.
“I am very happy we landed in the winning circle. This would be a big help particularly in addressing our health-related problems. One of the Sustainable Development Goals (SDGs) is on Good Health and Well Being and the problem they are trying to address is analysis related to dengue,“ said Science and Technology secretary Fortunato T. de la Peña. Rex Lor from the United Nations Development Programme (UNDP) in the Philippines explained that the winning solution showcases the “pivotal role of cutting-edge digital technologies in the creation of strategies for sustainable development in the face of evolving development issues.”
U.S Public Affairs counselor Philip W. Roskamp and PLDT Enterprise Core Business Solutions vice president and head Joseph Ian G. Gendrano congratulates the next group of Pinoy winners.
Sec. de la Peña is also very happy on this second time victory for the Philippines on the global competition of NASA. The first winning solution ISDApp uses “data analysis, particularly NASA data, to be able to help our fishermen make decisions on when is the best time to catch fish.” It is currently being incubated by Animo Labs, the technology business incubator and Fab Lab of De La Salle University in partnership with DOST-PCIEERD. Project AEDES will be incubated by Animo Labs too.
University president Br. Raymundo B. Suplido FSC hopes that NASA Space Apps would “encourage our young Filipino researchers and scientists to create ideas and startups based on space science and technology, and pave the way for the promotion and awareness of the programs of our own Philippine space agency.”
Philippine vice president Leni Robredo recognized Space Apps as a platform “where some of our country’s brightest minds can collaborate in finding and creating solutions to our most pressing problems, not just in space, but more importantly here on Earth.”
“Space Apps is a community of scientists and engineers, artists and hackers coming together to address key issues here on Earth. At the heart of Space Apps are data that come to us from spacecraft flying around Earth and are looking at our world,” explained by Dr. Thomas Zurbuchen, NASA associate administrator for science.
“Personally, I’m more interested in supporting the startups that are coming out of the Space Apps Challenge,” according to DOST-PCIEERD executive director Dr. Enrico C. Paringit.
In the Philippines, Space Apps is a NASA-led initiative organized in collaboration with De La Salle University, Animo Labs, DOST-PCIEERD, PLDT InnoLab, American Corner Manila, U.S. Embassy, software developer Michael Lance M. Domagas, and celebrates the Design Week Philippines with the Design Center of the Philippines of the Department of Trade and Industry. It is globally organized by Booz Allen Hamilton, Mindgrub, and SecondMuse.
Space Apps is a NASA incubator innovation program. The next hackathon will be on October 2–4, 2020.

Salamanders and lizards can regrow limbs. Certain worms and other creatures can generate just about any lost part — including a head — and the latest genetics research on body part regeneration is encouraging.
Since they are adult stem cells that have reverted back to a less developed — more pluripotent — state, iPSCs remind scientists of the stem cells that enable lizards to regrow limbs, and zebrafish to regrow hearts. When it comes to limbs, the understanding the regrowth process could help scientists promote nerve regeneration in cases when a limb is severely damaged, but not physically lost. Nerves of the human peripheral nervous system do have the ability to regrow, but whether this actually happens depends on the extent of the injury, so understanding the stem cell physiology in zebrafish and other animals could help clinicians fill the gap. The knowledge gained also could impact development of treatments aimed at promoting nerve regrowth in the central nervous system, for instance in the spinal cord after an injury.
Caveats
Even where regeneration is natural for humans, numerous regeneration cycles can put a person at greater risk of cancer. In the liver, for instance, disease can result in liver cancer largely because the organ produces new cells to replace the damaged ones. This is what happens in cirrhosis and after certain viral conditions when there are periods when regeneration overtakes liver deterioration. Prometheus avoided this fate, but we don’t know how well the process would work in humans, if a regenerative system based on iPSCs or some other types of stem cell is used clinically on a large scale. Regenerative medicine is promising and exciting to hear about. But we are at a very early stage, and reports on limb regrowth should be taken with caution.
Computer scientists established a new boundary on computationally verifiable knowledge. In doing so, they solved major open problems in quantum mechanics and pure mathematics.
From the US territory Guam, sightings came in of a fireball falling from the sky. The strategic location of Guam and the U.S. military stationed there has drawn attention for years. Guam thrust into the limelight during heightened tensions with North Korea. In August 2017, North Korea launched missiles that flew over Japan and into the northern Pacific Ocean in an apparent attempt to threaten the US territory of Guam. North Korean leader Kim Jong Un did not follow up on his threats, but a fireball came crashing down from a different source.
Local officials quickly released an announcement indicating the Chinese Long March Launch as a likely source of the fireball. Indeed, an Indonesia satellite launched on a Chinese rocket came crashing back to Earth. The satellite failed to reach orbit. The failure of the new communications satellite for Indonesia to reach orbit marked the second failure for china’s space agency in less than a month, state media reported April 9.
It is unlike the Chinese Long March 3, workhorse of the Chinese launch industry, series rocket to fall. According to the Xinhua News Agency, the rocket lifted off at 7:46 p.m local time from China’s Xichang Satellite Launch Center in the Sichuan province. The rocket traveled according to plan during the first and second stages. The Rocket third stage experienced abnormal conditions.
The ESA probe BepiColombo flew past Earth on the way to Mercury. The probe launched in 2018 and made the last visit of our home before continuing onward to the final destination. The spacecraft needs to shed velocity to arrive at Mercury in 2025 at a velocity to enter orbit. The spacecraft will make multiple additional planetary flybys of Venus and Mercury to slow down to enter orbit.
In space travel, mission planners need to balance mission resources. The amount of fuel required to either speed up or slow down a spacecraft greatly impacts the cost of the mission. Using a longer flight path can reduce the propellent requirements for a mission but the mission will take longer. Gravity assists can, therefore, allow a spacecraft to be launched on a cheaper, less powerful rocket.
Gravity assist flyby?
A Gravity assist flyby has other names including a gravitational slingshot, gravity assist maneuver, or swing-by. Gravity assistance maneuvers increase or decrease its speed or redirect the orbital path. The spacecraft slingshots around another object with a gravitational field and transfers some of the energy during that slingshot. In the case of BepiColombo, the spacecraft needs to slow down to be captured by Mercury…

If you’ve been interested in nanotech, but have been too afraid to ask, here is an introductory and interesting article that I’d like to recommend.
My interest in nanotech is based on my hope that nanotech can lead to methods of constructing substrates that are suitable for mind uploading. It may lead to a technique to create duplicate minds.
“These ‘biological engineering’ technologies have made real one of the dreams of the nanotechnology pioneers: the deployment of molecular assemblers able to construct any shape with atomic precision, following a rational design.”
“…hybrid bioinorganic devices that mimic biological processes will soon be used in new computers and electronic devices.”
In the mid-1980s, evidence started to emerge from labs across the world confirming that scientists were finally able to reach the nano level in experimental conditions and not just with their theories. Working at scales defined in millionths of a millimetre, Richard Smalley, Robert Curl and Harold Kroto reported the discovery of ‘buckminsterfullerene’ – a nanosized polyhedron, with 32 faces fused into a cage-like, soccer-ball structure, and with carbon atoms sitting in each of its 60 vertices.
These miniature ‘Bucky’ balls (named for their similarity to the geodesic dome structures made by the architect R Buckminster Fuller in the 1950s), are found in tiny quantities in soot, in interstellar space and in the atmospheres of carbon-rich red giant stars, but Kroto was able to recreate them in chemical reactions in the lab while visiting Rice University in Texas. Then, in 1991, Nadrian Seeman’s lab at New York University used 10 artificial strands of DNA to create the first human-made nanostructure, connecting up the DNA strands to resemble the edges of a cube, so marking the beginning of the field now known as ‘DNA nanotechnology’. Clever scientists with broad visions started to realise that a new kind of technology, prophesied by Richard Feynman in the 1950s, was finally materialising, as researchers achieved the capacity to visualise, fabricate and manipulate matter at the nanometre scale.
The term nanotechnology was coined in 1974 by the Japanese scientist Norio Taniguchi to describe semiconductor processes involving engineering at the nanoscale, but it entered public debate only with the publication of K Eric Drexler’s influential Engines of Creation (1986), a hyperbolic book of futuristic scientific imaginings of what might be achieved on the scale of the unimaginably small. Drexler’s book sparked longlasting controversies, notably focused on the weak scientific grounding of some of his ideas; but nothing stuck more to the public consciousness than his prediction of a hypothetical ‘grey goo’, scourge of a global dystopia involving out-of-control self-replicating machines devouring all life on Earth.
A heads up: Dyson has “created 44 engineering and science activities for children to try out while at home during the coronavirus pandemic, from making a balloon-powered car to building a bridge from spaghetti,” writes the Dezeen website. They go on to add: “Comprised of 22 science tasks and 22 engineering activities, the Challenge Cards can be completed by children using common household items such as eggs, string and balloons.” You can also find a related playlist of videos on YouTube, one of which appears above.
