Unveiling Biology with Deep Microscopy

Posted by in categories: biotech/medical, finance, information science, military, robotics/AI, space

The scientific revolution was ushered in at the beginning of the 17th century with the development of two of the most important inventions in history — the telescope and the microscope. With the telescope, Galileo turned his attention skyward, and advances in optics led Robert Hooke and Antonie van Leeuwenhoek toward the first use of the compound microscope as a scientific instrument, circa 1665. Today, we are witnessing an information technology-era revolution in microscopy, supercharged by deep learning algorithms that have propelled artificial intelligence to transform industry after industry.

One of the major breakthroughs in deep learning came in 2012, when the performance superiority of a deep convolutional neural network combined with GPUs for image classification was revealed by Hinton and colleagues [1] for the ImageNet Large Scale Visual Recognition Challenge (ILSVRC). In AI’s current innovation and implementation phase, deep learning algorithms are propelling nearly all computer vision-intensive applications, including autonomous vehicles (transportation, military), facial recognition (retail, IT, communications, finance), biomedical imaging (healthcare), autonomous weapons and targeting systems (military), and automation and robotics (military, manufacturing, heavy industry, retail).

It should come as no surprise that the field of microscopy would ripe for transformation by artificial intelligence-aided image processing, analysis and interpretation. In biological research, microscopy generates prodigious amounts of image data; a single experiment with a transmission electron microscope can generate a data set containing over 100 terabytes worth of images [2]. The myriad of instruments and image processing techniques available today can resolve structures ranging in size across nearly 10 orders of magnitude, from single molecules to entire organisms, and capture spatial (3D) as well as temporal (4D) dynamics on time scales of femtoseconds to seconds.

EnVision and the Cosmic Vision decision

Posted by in categories: evolution, mapping, space

In 2016, the European Space Agency announced a call for medium-size missions within their Cosmic Vision Program. In layman’s terms, “medium-size” means moderate-cost (less than 550 million euros, or $610 million) and low-risk, and this is achieved by keeping payloads small and by using proven, heritage technology for both spacecraft and payload. Alongside these common-sense conditions is a third and less tangible quality, that the project be scientifically robust. But when comparing excellent cases from vastly different fields, the merits of one scientific mission over another can seem subjective. It’s not enough to lament the dearth of data in said field, or to establish how a project will discover this or that, or even to show exactly how said “groundbreaking technology” will work. ESA wants a mission that will stir up an unprecedented level of excitement, support, and interest within the scientific community. Here is how they attempt to measure a project’s relevance.

“Each member state has a representative in the Science Programme Committee, and it’s their duty to define the content of the program,” said Luigi Colangeli, head of ESA’s Science Coordination Office. “Study groups work with the various proposals to arrive at something that is compatible with the boundary conditions, in this case, of a M-5, or medium-class mission. Right now, we are studying the evolution of the three missions. And then next year we will put together a peer review panel, who will analyze the three candidates and recommend the best selection to our Director of Science.”

Since the call went out four years ago, ESA have been whittling down proposals, from 25 at the beginning to only three now: Envision, Theseus, or SPICA. In February the EnVision conference took place at the National Centre for Space Studies (CNES) in Paris. EnVision is a low-altitude polar orbiter that is meant to perform high-resolution radar mapping, surface composition, and atmospheric studies of Venus. The purpose of the meeting was to call the Venus community to attention, because the clock is ticking. Consortium members, ESA representatives, and interested scientists from all over the world were in attendance.

Trillions of Earths, 300 Sextillion Stars Say Scientists

Posted by in category: space

The universe just got a lot more crowded. According to a new study, there may be three times as many stars in the universe as previously thought. How many? Three-hundred sextillion. How many is 300 sextillion? Behold:

300,000,000,000,000,000,000,000

That is, as the Associated Press points out, three trillion times 100 billion.

Scientists Claim to Have Found The First Known Extraterrestrial Protein in a Meteorite

Posted by in category: space

A new discovery could be a clue for us to see if life could emerge elsewhere in the Solar System. Using a new analysis technique, scientists think they have found an extraterrestrial protein, tucked inside a meteorite that fell to Earth 30 years ago.

If their results can be replicated, it will be the first protein ever identified that didn’t originate here on Earth.

“This paper characterises the first protein to be discovered in a meteorite,” the researchers wrote in a paper uploaded to preprint server arXiv. Their work is yet to be peer reviewed, but the implications of this finding are noteworthy.

L3Harris wins $1.2 billion contract to maintain, upgrade space surveillance systems

Posted by in categories: military, space, surveillance

WASHINGTON — L3Harris has been awarded a 10-year $1.2 billion contract by the U.S. Space Force’s Space and Missile Systems Center to maintain and modernize the military’s network of space surveillance sensors.

The award is for a new program named MOSSAIC, short for maintenance of space situational awareness integrated capabilities. The selection of L3Harris was announced Feb. 25 on the beta. SAM.gov federal contracting opportunities website.

MOSSAIC replaces a previous contract that Harris (before it merged with L3) had held since 2002 to maintain the Air Force’s network of telescopes — known as the Ground-based Electro-Optical Deep Space Surveillance System — that track objects in geostationary orbits. Now under control of the U.S. Space Force are three GEODSS sites — on the island of Diego Garcia in the Indian Ocean; at the White Sands Missile Range, New Mexico; and in Maui, Hawaii.
