Canadian NIRISS instrument on Webb Maps an Ultra-Hot Jupiter’s Atmosphere
Using the Canadian NIRISS instrument on the James Webb Space Telescope, astrophysics PhD candidate Louis-Philippe Coulombe has mapped the atmosphere of the intriguing exoplanet WASP-18 b. There's an intriguing exoplanet out there - 400 light-years out there - that is so tantalising that astronomers have been studying it since its discovery in 2009.

Bird brains can flick switch to perceive Earth’s magnetic field
Understanding how animals make their way around in the world helps determine things humans are doing that might influence them Earth's magnetic field, generated by the flow of molten iron in the planet's inner core, extends out into space and protects us from cosmic radiation emitted by the Sun. It is also, remarkably, used by animals like salmon, sea turtles and migratory birds for navigation.

Astronomers double the number of repeating cosmic probes
Science, Health & Technology Alex Walls A Canadian-led research team has doubled the number of repeating fast radio bursts, adding 25 new 'cosmic probes'. Fast radio bursts (FRBs) are cosmic radio signals: extremely short, energetic pulses of radio emission emanating from space. They're an astronomical mystery, as scientists aren't sure exactly what causes them and where they come from.

First space images captured by balloon-borne telescope
Astronomers have successfully launched a balloon-borne telescope that has begun capturing images of the universe on its first flight above the Earth's atmosphere. The Super Pressure Balloon-Borne Imaging Telescope (SuperBIT) was flown to the edge of space by a helium-filled NASA scientific balloon the size of a football stadium.

How different were galaxies in the early universe?
An array of 350 radio telescopes in the Karoo desert of South Africa is getting closer to detecting the -cosmic dawn the era after the Big Bang when stars first ignited and galaxies began to bloom. A team of scientists from across North America, Europe, and South Africa has doubled the sensitivity of a radio telescope called the Hydrogen Epoch of Reionization Array ( HERA ).

Detailed map of matter in the cosmos confirms Einstein’s theory of general relativity, astronomers say
Researchers from the Atacama Cosmology Telescope (ACT) collaboration have submitted a set of papers to the Astrophysical Journal featuring a groundbreaking new map of dark matter distributed across a quarter of the entire sky and extending deep into the cosmos. The result confirms Albert Einstein's theory of general relativity - which predicts how massive structures grow and bend light - with a test that spans the 14-billion-year life of the universe.

In two places at once
An UdeM study finds that a gravitational field does not seem to know where a particle that has been split in two, quantum mechnically, is, instead taking its average position as the as the only one. Anyone with a high-school diploma knows about Newton's law of universal gravitation: it's that the gravitation force behaves like 1 over the distance squared as you separate from a gravitating mass.

Researchers’ model could help avert global helium supply crisis
A new theoretical model developed by earth scientists at the University of Oxford, University of Toronto and Durham University may help alleviate a global supply shortage of helium - a naturally occurring gas critical for a wide range of medical, scientific and industrial applications, from cooling the magnets of MRI scanners to filling non-combustible balloons.

Researchers at the University of Toronto have developed a method of harnessing artificial intelligence to discover new and more efficient materials for clean energy technology. A team led by Alex Voznyy , an assistant professor in the department of physical and environmental sciences at University of Toronto Scarborough, used machine learning to significantly speed up the amount of time needed to find new materials with desired properties.

’Liquid windows’ inspired by squid skin could help buildings save energy
Inspired by the dynamic colour-changing skin of organisms such as squid, University of Toronto researchers have developed a multilayered fluidic system that can reduce the energy costs of heating, cooling and lighting buildings. The platform, which optimizes the wavelength, intensity and dispersion of light transmitted through windows, offers much greater control than existing technologies while keeping costs low due to its use of simple, off-the-shelf components.

Astronomers capture radio signal from distant galaxy
How do stars form in distant galaxies? Astronomers have long been trying to answer this question by detecting radio signals emitted by nearby galaxies. However, these signals become weaker the further away a galaxy is from Earth, making it difficult for current radio telescopes to pick up. Now researchers from Montreal and India have captured a radio signal from the most distant galaxy so far at a specific wavelength known as the 21 cm line, allowing astronomers to peer into the secrets of the early universe.

Experimental physicists take step toward understanding natural quantum systems
"Suppose you knew everything there was to know about a water molecule - the chemical formula, the bond angle, etc.," says experimental physicist Joseph Thywissen . "You might know everything about the molecule, but still not know there are waves on the ocean - much less how to surf them," he says.

What causes some icicles to form with ripples
Experimental physicists at the University of Toronto are closer to understanding why some icicles form with ripples up and down their outsides, while others form with smooth, slick, even surfaces. By growing icicles from water samples with different contaminants like sodium chloride (salt), dextrose (sugar) and fluorescent dye, the researchers discovered that water impurities become entrapped within icicles as they form and subsequently create chevron patterns that contribute to a ripple effect around their circumferences.

One step closer to developing a potentially ultraprotective sunscreen from our own melanin
A new discovery about the structure of melanin has brought scientists one step closer to developing a new, potentially ultra-protective sunscreen derived from a biological substance found in nearly all organisms. Researchers from McGill's Department of Chemistry, in collaboration with The Ohio State University and the University of Girona, have announced a major advance in understanding the fundamental structure of melanin and one of its components that turns light into heat, protecting the body from sun damage.

New insight into the enigmatic realm of ’strange metals’
The behaviour of so-called "strange metals" have long puzzled scientists - but a group of researchers at the University of Toronto may be one step closer to understanding these materials. Electrons are discrete, subatomic particles that flow through wires like molecules of water flowing through a pipe.

New discovery may be key to controlling chemical reactions
Unexpected resonance frequencies observed in reactions between two molecules A new study published today in Nature is changing our understanding of chemical reactions and overturning previous theoretical models by finding an unexpected resonance frequency during the reaction of two molecules. Resonance is when one object vibrating at the same natural frequency as a second object forces that second object into vibrational motion.
