SkyWatch and Picterra combine imagery access with AI tools

Posted by in categories: business, information science, robotics/AI, satellites

SkyWatch Space Applications, the Canadian startup whose EarthCache platform helps software developers embed geospatial data and imagery in applications, announced a partnership Oct. 5 with Picterra, a Swiss startup with a self-service platform to help customers autonomously extract information from aerial and satellite imagery.

“One of the things that has been very difficult to achieve is this ability to easily and affordably access satellite data in a way that is fast but also in a way in which you can derive the insights you need for your particular business,” James Slifierz, SkyWatch CEO told SpaceNews. “What if you can merge both the accessibility of this data with an ease of developing and applying intelligence to the data so that any company in the world could have the tools to derive insights?”

SkyWatch’s EarthCache platform is designed to ease access to aerial and satellite imagery. However, SkyWatch doesn’t provide data analysis.

China pushes ahead with giant 13,000 satellite LEO constellation

Posted by in categories: internet, policy, satellites, space

China is pushing ahead with developing a giant Low Earth Orbit (LEO) satellite constellation competing with SpaceX, Amazon and OneWeb, according to the Washington DC-based analyst Bhavya Lal and California State University’s Professor Larry Press.

Press, professor of information systems at the California State University, mentioned a recent Chinese spectrum filing in a blog of the CircleID website. China “has filed a spectrum application with the International Telecommunication Union for two constellations with the cryptic names GW-A59 and GW-2″ for a total of 12,992 satellites, Press said.

“We heard about an announcement of a constellation with nearly 13,000 satellites,” Bhavya Lal said in SpaceWatchGlobal’s Space Café webtalk last week. Lal is a senior space policy analyst at the IDA Science and Technology Policy Institute in Washington DC and was in the lead for IDA’s recently published report “Evaluation of China’s Commercial Space Sector”.

High throughput screening identifies molecules that reduce cellular stress

Posted by in categories: biotech/medical, life extension

For many, getting older can unfortunately mean an increased risk of illness from cardiovascular disease to cancer. University of Michigan scientists are actively researching the biological underpinnings of aging with the aim of developing interventions that could potentially help people live longer, healthier lives.

A new paper in the journal Science Advances describes the discovery of several promising small molecules that appear to reduce in mouse skin and could lengthen life.

“Cellular resistance appears to be a common feature of long-lived organisms, such as invertebrates and mice,” says the paper’s lead author David Lombard, M.D., Ph.D., associate professor of pathology. Lombard is part of a multidisciplinary group at U-M’s Paul F. Glenn Center for Aging. Recent research from colleague and fellow study author Richard Miller, M.D., Ph.D., found several promising drugs, including rapamycin, a cancer drug, and acarbose, a diabetes drug, that extended life in mice.

Scientists dazed and confused by extraordinary amount of gold in the universe

Posted by in category: space

They say if you spread out all the gold ever mined from the Earth in all of history, it would only cover a football field 18 inches deep.

Now when you wrap you mind around that image, it doesn’t seem like very much, especially when you digest the fact that the solar system is literally brimming with gold but scientists can’t quite figure out where all this hard-to-make metal is being created.

Watch this 1.2 Megawatt electric motorcycle break the world record in 6-second drag race

Posted by in categories: sustainability, transportation

When Danish racing team True Cousins got started with electric motorcycle racing, their first attempt was rather modest. But twelve years after fielding their first custom 12 kW electric motorcycle, the team returned to set a new world record with a new bike featuring 100x the power.

The Silver Lightning is a custom built electric drag racing motorcycle featuring up to 1,200 kW of power.

Last week it laid rubber down on the strip at the Santa Pod Raceway in Bedfordshire, England during the event dubbed “NOT the Euro Finals”.

CERN Timepix Technology Helps Rediscover Lost Painting by the Great Renaissance Master, Raphael

Posted by in categories: media & arts, particle physics, robotics/AI

CERN’s Timepix particle detectors, developed by the Medipix2 Collaboration, help unravel the secret of a long-lost painting by the great Renaissance master, Raphael. 500 years ago, the Italian painter Raphael passed away, leaving behind him many works of art, paintings, frescoes, and engravings.


CERNs Timepix particle detectors, developed by the Medipix2 Collaboration, help unravel the secret of a long-lost painting by the great Renaissance master, Raphael.

500 years ago, the Italian painter Raphael passed away, leaving behind him many works of art, paintings, frescoes, and engravings. Like his contemporaries Michelangelo and Leonardo da Vinci, Raphael’s work made the joy of imitators and the greed of counterfeiters, who bequeathed us many copies, pastiches, and forgeries of the great master of the Renaissance.

Cambodia confirms US-funded defence facility has been razed

Posted by in category: military

Cambodia has razed a US-funded defence facility on its southern coast, the deputy prime minister confirmed Sunday, the latest move in the ongoing controversial expansion of a strategically crucial naval base being developed with Chinese aid.

The Wall Street Journal reported last year on a secret draft deal allowing China to dock warships at the Ream naval base near the kingdom’s coastal city of Sihanoukville.

But Cambodia — awash in recent years with Chinese investments — has strenuously denied the report, although strongman premier Hun Sen has said aid from Beijing will fund the naval base’s development.

World’s first direct observation of the magneto-Thomson effect

Posted by in categories: energy, physics

Applying a temperature gradient and a charge current to an electrical conductor leads to the release and absorbtion of heat. This is called the Thomson effect. In a first, NIMS and AIST have directly observing the magneto-Thomson effect, which is the magnetic-field-induced modulation of the Thomson effect. This success may contribute to the development of new functions and technologies for thermal energy management and to advances in fundamental physics and materials science on magneto-thermoelectric conversion.

The Seebeck effect and the Peltier effect have been extensively investigated for their application to thermoelectric conversion technologies. Along with these effects, the Thomson effect has long been known as a fundamental thermoelectric effect in metals and semiconductors. Although the influence of magnetic fields and magnetism on the Seebeck and Peltier effects has been well understood as a result of many years of research, the influence on the Thomson effect has not been clarified because it is difficult to measure and evaluate.

This NIMS-led research team observed heat release and absorption induced in an electrical conductor by simultaneously creating a temperature gradient across it, passing a charge current through the gradient, and applying a magnetic field. The team precisely measured temperature changes in the conductor associated with the heat release and absorption using a heat detection technique called lock-in thermography. As a result, the amount of heat released and absorbed was found to be proportional to both the magnitude of the temperature gradient and charge current. In addition, the team observed strong enhancement of the resultant temperature change when a magnetic field was applied to the conductor. The systematic measurements performed in this study demonstrated that the heat release and absorption signals detected under a magnetic field were indeed generated by the magneto-Thomson effect.
