A novel algorithm developed by University of Washington researchers to discover asteroids in the solar system has proved its mettle. The first candidate asteroids identified by the algorithm — known as Tracklet-less Heliocentric Orbit Recovery, or THOR — have been confirmed by the International Astronomical Union’s Minor Planet Center.

The Asteroid Institute, a program of B612 Foundation, has been running THOR on its cloud-based astrodynamics platform — Asteroid Discovery Analysis and Mapping, or ADAM — to identify and track asteroids. With confirmation of these new asteroids by the Minor Planet Center and their addition to its registry, researchers using the Asteroid Institute’s resources can submit thousands of additional new discoveries.

In response to a request from the province of British Columbia (BC), from January 31, 2023 to January 31, 2026, adults (18 and over) in BC will not be subject to criminal charges for the possession of up to 2.5 grams of certain illegal drugs for personal use.

The federal Minister of Mental Health and Addictions and Associate Minister of Health granted the province of British Columbia (BC)’s request for a subsection 56 exemption under the Controlled Drugs and Substances Act for adults (18 years of age and older) in the province to possess small amounts of certain illegal drugs for personal use. BC has referred to this as “decriminalization of personal possession of illegal drugs”.

What this means is that from January 31, 2023 to January 31, 2026, adults (18 and over) in BC will not be subject to criminal charges for the possession of a cumulative total of up to 2.5 grams of certain illegal drugs for personal use. Instead, all individuals found in possession of substances listed in the exemption of up to 2.5 grams for personal use will, at minimum, be provided with information on available local health and social services. They can also be provided with assistance to connect with those services if requested. The exemption only covers possession for personal use by adults (18 and over) in BC with no intent to traffic, produce or export.

British Columbia has been greatly impacted by overdose deaths and related harms, and declared the overdose crisis a public health emergency in 2016. As part of the province’s comprehensive public health response, BC requested a subsection 56 exemption under the Controlled Drugs and Substances Act (CDSA) so that adults in the province will not be subject to criminal charges for personal possession of small amounts of certain illegal drugs.

U.S. retail giant Walmart is bringing the convenience of drone delivery to four million households, in partnership with DroneUp.

Although the media has reported that the Zuma Spacecraft had failed right off the ground many believe that this was all a lie made to essentially make people forget about it.

This has only been further proven by the mysterious flash that appeared on the night’s sky causing a ton of ground shaking over thousands of miles in Russia.

The world’s first exascale computer, capable of performing a billion billion operations per second, has been built by Oak Ridge National Laboratory (ORNL) in the US.

A typical laptop is only capable of a few teraflops, or a trillion operations per second, which is a million times less. The exaflop machine, called Frontier, could help solve a range of complex scientific problems, such as accurate climate modelling, nuclear fusion simulation and drug discovery.

“Frontier will offer modelling and simulation capabilities at the highest level of computing performance,” says Thomas Zacharia at ORNL.

Most 3D printing methods currently in use rely either on photo (light)- or thermo (heat)-activated reactions to achieve precise manipulation of polymers. The development of a new platform technology called direct sound printing (DSP), which uses soundwaves to produce new objects, may offer a third option.

The process is described in a paper published in Nature Communications. It shows how focused ultrasound waves can be used to create sonochemical reactions in minuscule cavitation regions—essentially tiny bubbles. Extremes of temperature and pressure lasting trillionths of a second can generate pre-designed complex geometries that cannot be made with existing techniques.

“Ultrasonic frequencies are already being used in destructive procedures like laser ablation of tissues and tumors. We wanted to use them to create something,” says Muthukumaran Packirisamy, a professor and Concordia Research Chair in the Department of Mechanical, Industrial and Aerospace Engineering at the Gina Cody School of Engineering and Computer Science. He is the paper’s corresponding author.

Astronomers have used a cloud-based technique pioneered at the University of Washington to identify and track asteroids in bunches of a hundred or more. Their achievement could dramatically accelerate the quest to find potentially threatening space rocks.

The technique makes use of a cloud-based, open-source analysis platform known as Asteroid Discovery Analysis and Mapping, or ADAM; plus a recently developed algorithm called Tracklet-less Heliocentric Orbit Recovery, or THOR. The THOR algorithm was created by Joachim Moeyens, an Asteroid Institute Fellow at UW; and Mario Juric, director of UW’s DiRAC Institute.

NASA’s flying telescope SOFIA has been watching a dance between two stars orbiting each other as they approach the moment of eclipse, allowing astronomers to study how the two exchange stardust.
