How female false widow spiders use their ’spidey senses’ to attract mates - study
When it comes to spider love, female widow spiders hold the key to attracting mates, potentially adjusting their web-s attractiveness to lure males, according to new research. A study led by Simon Fraser University's resident -spider man,- PhD candidate Andreas Fischer, reveals new details about how female false widow spiders ( Steatoda grossa) communicate using pheromones-and suggests they can build more attractive webs- to lure mate-seeking males by adjusting the pH level of their pheromone-bearing silk.

The solar ballet of the white trillium
The solar ballet of the white trillium
The flowers of the white trillium follow the sun, which increases their fecundity, according to a research team in biological sciences at UdeM. Have you ever noticed, during your walks in the forest, that the flowers of the white trilliums all point in the same direction? In fact, the flowers are pointing south, towards the sun, and this is far from being a coincidence.

An ultra-light photo collar to study lemmings
An ultra-light photo collar to study lemmings
Developed by a team at Laval University, this collar, which weighs less than a dime, will allow the study of lemming activity patterns during the summer Although lemmings play a central role in the Arctic terrestrial food chain, their living habits are still largely unknown. One reason is that these small rodents spend most of the year in tunnels in the ground or snow, out of sight of researchers.

Researchers shrink brain tumours with gold nanoparticles, develop ’mini brains’ to study psychiatric disorders
Researchers at the University of Toronto are inching closer to realizing a life-saving brain cancer treatment by using gold nanoparticles to make radiation therapy more effective and less toxic for patients. In their battle against glioblastoma multiforme (GBM), a rare, fast-growing cancer that begins in the brain, the multidisciplinary team has discovered that the nanoparticles can keep radiation tightly focused on the tumour, shrinking its size and preventing damage elsewhere in the body.

Researcher combines AI and microelectronics to create neural implants that fight brain disorders
Researcher combines AI and microelectronics to create neural implants that fight brain disorders
Neural implants can help treat brain disorders such as Parkinson's disease and epilepsy by directly modulating abnormal activities - and the University of Toronto's  Xilin Liu  is working with microelectronics and artificial intelligence to make this emerging technology both safer and smarter. "Neurons talk to each other in part via electrical signals, and a therapeutic neural implant produces electrical stimulation - like a pacemaker for the brain," says Liu, an assistant professor in the Faculty of Applied Science & Engineering.

A one-stop-shop for brain imaging
A one-stop-shop for brain imaging
Software tool brings together multiple brain maps in one place The brain is a complex organ, and no one imaging mode can catch everything that's going on inside it. Over the years, multiple -brain maps- have emerged, each focusing on different brain processes, from metabolism to cognitive function. While these maps are important, using them in isolation limits the discoveries researchers can make from them.

The surprising Swiss-Army-knife-like functions of a powerful enzyme
The surprising Swiss-Army-knife-like functions of a powerful enzyme
Blue-green algae (AKA cyanobacteria) have a superpower which likely helps them be highly successful as invaders of waterways. They have an extraordinary ability to store energy and nitrogen in their cells for times of need. But how exactly they do so remains only partly understood. Now researchers from McGill University and their collaborators at ETH Zurich have uncovered an intriguing hitherto unknown ability of the enzymes (known as cyanophycin synthetases) that are active in creating these food reserves.

A new understanding of the neurobiology of impulsivity
A new understanding of the neurobiology of impulsivity
While not all impulsive behaviour speaks of mental illness, a wide range of mental health disorders which often emerge in adolescence, including depression and substance abuse, have been linked to impulsivity. So, finding a way to identify and treat those who may be particularly vulnerable to impulsivity early in life is especially important.
