From helping catalyze interstellar reactions and fueling the birth of stars to its presence in neighborhood gas giants like Saturn and Jupiter, trihydrogen, or H3+, is best known as the “the molecule that made the universe.”

While we have a clear picture of how the majority of H3+ is formed—a hydrogen molecule, or H2, colliding with its ionized counterpart, H2+—scientists are keen to understand alternative sources of H3+ and to better measure its abundance throughout the cosmos...

Newly discovered ‘Ovoid’ brain cells reshape understanding of how memory works

Meet the newly discovered brain cell that allows you to remember objects

Take a look around your home and you’ll find yourself surrounded by familiar comforts—photos of family and friends on the wall, well-worn sneakers by the door, a shelf adorned with travel mementos. Objects like these are etched into our memory, shaping who we are and helping us navigate environments and daily life with ease. But how do these memories form? And what if we could stop them from slipping away under a devastating condition like Alzheimer’s disease?

Scientists at UBC’s faculty of medicine have just uncovered a crucial piece of the puzzle. In a study published in Nature Communications, the researchers have discovered a new type of brain cell that plays a central role in our ability to remember and recognize objects.

Called “ovoid cells,” these highly-specialized neur...

Prototype turns car and helicopter exhaust into thermoelectric energy

Researchers design and test a waste-heat recovery system, illustrated here, that attaches to a car tailpipe and converts heat from exhaust into energy. The fanned grooves on the outside of the pipe are the cold side of the device’s heatsink and the triangular components inside the pipe are plate-fin heat exchangers.

Combustion engines, the engines in gas-powered cars, only use a quarter of the fuel’s potential energy while the rest is lost as heat through exhaust.

Now, a study published in ACS Applied Materials & Interfaces demonstrates how to convert exhaust heat into electricity...

Astronomers announce largest collection of comets found outside our solar system

74 images o different star systems
Caption: This gallery contains 74 images of different star systems with cometary belts (known as “exocomets”) taken with the Submillimeter Array (SMA) and the Atacama Large Millimeter/submillimeter (ALMA) radio telescope facilities. The stars in this study range in ages from very young to middle-aged like our Sun. This new study shows how comets play a role in the formation of stars and planetary systems.

For the first time, astronomers have imaged dozens of belts around nearby stars where comets and tiny pebbles within them are orbiting.

This result reveals regions around 74 stars spanning a wide range of ages—from those recently formed to others billions of years old—showing how comets play a role in the formation of stars and planetary systems...
