Canada proposes POET mission to hunt Earth-sized planets‎

Exoplanet science and the search for life beyond Earth continue to advance at break-neck speeds, with the number of confirmed exoplanets by NASA rapidly approaching 6,300, with 223 of those exoplanets being designated as terrestrial (rocky) exoplanets. With the promise of discovering an increasing number of Earth-sized exoplanets increasing every day, new telescopes from across the world have the opportunity to contribute to this incredible field.

Why Eurovision stays unpredictable after 70 years of copycats and rule changes‎

The Eurovision Song Contest (ESC) has been attracting millions of fans every year since it was launched back in 1956. At the same time, it represents a unique opportunity for research. Almost no other major cultural event has been so well documented over such an extended period of time. Data on songs, voting and rule changes is freely accessible, making Eurovision an ideal example for computer-assisted social sciences of a data-based culture system.

A new interface to study RNA biology‎

Scientists at Université de Montréal's Institute for Research in Immunology and Cancer have developed a new database that integrates the molecular structure of microRNAs and messenger RNAs to systematically model their interactions. Called RIMap-RISC and developed by Ph.D. student Simon Chasles in the laboratory of UdeM professor François Major, director of IRIC's RNA engineering research unit, the database is detailed in a study published in Genome Biology.

Gold digging is not exclusive to women: New study uncovers common attributes‎

Gold digging is often seen as a female behavior focused on exploiting wealthier partners for material gain, but science suggests this stereotype may be too narrow. Past studies have shown both men and women value resources in partners, but not much research has delved into the specifics regarding gold digging versus general resource preference in partners.

Green alley effectiveness depends on design and purpose, study finds‎

Green alleys—residential laneways redesigned to enhance residents' quality of life, boost social cohesion and improve biodiversity—are gaining traction in cities across North America. But as the concept spreads, it remains loosely defined: what exactly counts as a green alley, and what benefits can it provide?

Locked in stone for 210 million years, this newly identified crocodile cousin was built to crush larger prey‎

On a fateful day 210 million years ago, two crocodile cousins about the size of jackals stood side-by-side amid the low ferns of a humid riverbank that would one day become northern New Mexico. One of the crocs, Hesperosuchus agilis, had a long snout, large back legs, and smaller, thinner arms. A land dweller, Hesperosuchus was speedy and liked to hunt for food near rivers and streams.

Plant-based diets cut climate impact by more than half, randomized clinical trial shows‎

As climate change accelerates and global temperatures continue to rise, a new randomized clinical trial provides compelling evidence that one of the most powerful climate solutions may be on our plates. A study published in Current Developments in Nutrition shows that adopting a low-fat vegan diet reduces diet-related greenhouse gas emissions by 55% and cumulative energy demand by 44%—dramatic reductions achieved in just 12 weeks.

Deadly feline coronavirus variant has been present in the US for more than a decade‎

Cornell researchers have discovered that a lethal variant of feline coronavirus, previously thought to be limited to a devastating 2023 outbreak in Cyprus that killed thousands of cats, has in fact appeared in the United States, raising concerns about future large-scale outbreaks in vulnerable cat populations.

Hidden plant molecules show up to 25 times stronger activity against Ebola and COVID-19‎

Scientists at the Université de Montréal's affiliated Montreal Clinical Research Institute (IRCM) have identified a new family of natural molecules with strong antiviral activity, notably against the Ebola virus and SARS-CoV-2, the virus responsible for COVID-19. The discovery comes at a time of renewed fears of the rapid emergence of new pandemics, and highlights the ongoing search at the IRCM for novel antiviral agents derived from natural sources.

Flooded fields across Midwest spur push for farm-tested solutions‎

Larry Dallas's farm in Central Illinois's Douglas County is as flat as it gets. That's a good thing for planting straight rows and maneuvering farm equipment in the field, but there's a major downside, too. "Heavier rain is hard for us to deal with because of the poorly drained soils and the lack of any roll to the ground. It's hard for the water to get away when the rain starts," Dallas said. "We have installed a lot of drainage tile trying to mitigate that."
