’Feel Good’ Brain Messenger Can Be Willfully Controlled
Neuroscientists show that mice can learn to manipulate random dopamine impulses for reward From the thrill of hearing an ice cream truck approaching to the spikes of pleasure while sipping a fine wine, the neurological messenger known as dopamine has been popularly described as the brain's "feel good" chemical related to reward and pleasure.

Measuring creativity, one word at a time
Can you think of three words that are completely unrelated to one another? What about four, five, or even ten? According to an international team of researchers from McGill University, Harvard University and the University of Melbourne, this simple exercise of naming unrelated words and then measuring the semantic distance between them could serve as an objective measure of creativity.

Cell structure previously associated with disease actually improves brain function
Researchers at McGill University have shown that a brain cell structure previously thought to be pathological in fact enhances cells' ability to transmit information and correlates with better learning on certain tasks. In a study published , the team investigated swellings that occur in the axons of Purkinje cells in the cerebellum.

Understanding our perception of rhythm
Scientists have long known that while listening to a sequence of sounds, people often perceive a rhythm, even when the sounds are identical and equally spaced. One regularity that was discovered over 100 years ago is the Iambic-Trochaic Law : when every other sound is loud, we tend to hear groups of two sounds with an initial beat.

Patently harmful: fewer female inventors a problem for women’s health
"Necessity is the father of invention," but where is its mother? According to a new study published in Science , fewer women hold biomedical patents, leading to a reduced number of patented technologies designed to address problems affecting women. While there are well-known biases that limit the number of women in science and technology, the consequences extend beyond the gender gap in the labour market, say researchers from McGill University, Harvard Business School, and the Universidad de Navarra in Barcelona.

Faecal records show Maya population affected by climate change
A McGill-led study has shown that the size of the Maya population in the lowland city of Itzan (in present-day Guatemala) varied over time in response to climate change. The findings, published recently in Quaternary Science Reviews , show that both droughts and very wet periods led to important population declines.

First CRISPR/Cas9-based Gene Drive in Plants
New technology designed to breed more robust crops to improve agricultural yield and resist the effects of climate change With a goal of breeding resilient crops that are better able to withstand drought and disease, University of California San Diego scientists have developed the first CRISPR-Cas9-based gene drive in plants.

Powerful People are Less Likely to be Understanding When Mistakes are Made
Those with privilege are less aware of constraints others face and are more likely to punish subordinates, according to new UC San Diego research Those with power, such as the wealthy are more likely to blame others for having shortcomings and they are also less troubled by reports of inequality, according to recent research from the University of California San Diego's Rady School of Management.

Data breaches: Most victims unaware when shown evidence of multiple compromised accounts
It's been nine years since the LinkedIn data breach, eight years since Adobe customers were victims of cyber attackers and four years since Equifax made headlines for the exposure of private information of millions of people. The number of data breaches and victims has multiplied rapidly over the past decade or so, but aside from these well-publicized cases, most participants in a recent University of Michigan study remained unaware that their email addresses and other personal information had been compromised in five data breaches on average.

The secret to acquiring professional skills
The secret to acquiring professional skills
While it is important for students to work in groups during their studies, that is not enough for them to acquire many of the transversal skills needed in the professional world. A recent EPFL study highlights the need for engineering courses to explicitly address professional skills through a combination of theory and feedback.

'Doomsday Glacier' may be more stable than initially feared
’Doomsday Glacier’ may be more stable than initially feared
The world's largest ice sheets may be in less danger of sudden collapse than previously predicted, according to new findings led by the University of Michigan. The study, published in Science, included simulating the demise of West Antarctica's Thwaites Glacier, one of the world's largest and most unstable glaciers.

Mountain fires burning higher at unprecedented rates
Forest fires have crept higher up mountains over the past few decades, scorching areas previously too wet to burn, according to researchers from McGill University. As wildfires advance uphill, a staggering 11% of all Western U.S. forests are now at risk. "Climate change and drought conditions in the West are drying out high-elevation forests, making them particularly susceptible to blazes," says lead author Mohammad Reza Alizadeha , a PhD candidate at McGill University under the supervision of Professor Jan Adamowski.

New mothers negatively impacted by COVID-19 pandemic policies
Giving birth can be a joyous, yet stressful experience in the best of times - but what happens when a global public health crisis is thrown into the mix? McGill University and the University of Toronto researchers examined the effects certain pandemic policies have had on the mental health of Canadian women who gave birth during the COVID-19 pandemic.

Over 500 new FRBs detected in single year due to CHIME telescope
Fast radio bursts, or FRBs, blaze for a few milliseconds before vanishing without a trace. Their origins are unknown, and their appearance is unpredictable. In the decade following their discovery in 2007, only 140 FRBs had been seen. Now, thanks to the launch of a large stationary telescope in the interior of British Columbia in 2018, the number of new FRBs detected has almost quadrupled - for a total of 535.

’Surfing’ particles: Physicists solve a mystery surrounding aurora borealis
The spectacularly colorful aurora borealis — or northern lights — that fill s the sky in high-latitude regions ha s fascinated people for thousands of years. Now, a team of scientists has resolved one of the final mysteries surrounding its origin. Scientists know that electrons and other energized particles that emanate from the sun as part of the "solar wind" speed down Earth's magnetic field lines and into the upper atmosphere, where they collide with oxygen and nitrogen molecules, kicking them into an excited state.

Vitamin D may not protect against COVID-19, as previously suggested
While previous research early in the pandemic suggested that vitamin D cuts the risk of contracting COVID-19, a new study from McGill University finds there is no genetic evidence that the vitamin works as a protective measure against the coronavirus. "Vitamin D supplementation as a public health measure to improve outcomes is not supported by this study.

Synthetic SPECIES Developed for Use as a Confinable Gene Drive
Researchers create novel CRISPR-based fly species as a new method of controlling gene drive spread CRISPR-based technologies offer enormous potential to benefit human health and safety, from disease eradication to fortified food supplies. As one example, CRISPR-based gene drives, which are engineered to spread specific traits through targeted populations, are being developed to stop the transmission of devastating diseases such as malaria and dengue fever.

Early bird or night owl? Study links shift worker sleep to ’chronotype’
Getting enough sleep can be a real challenge for shift workers affecting their overall health. But what role does being an early bird or night owl play in getting good rest? Researchers from McGill University find a link between chronotype and amount of sleep shift workers can get with their irregular schedules.

Hidden magma pools pose eruption risks that we can’t yet detect
Scientists' ability to estimate eruption risks is largely reliant on knowing where pools of magma are stored, deep in the Earth's crust. But what happens if the magma can't be spotted? Shane Rooyakkers , a former PhD candidate at McGill University's Department of Earth and Planetary Sciences and now a postdoctoral scholar at GNS Science in New Zealand, grew up in the shadow of Mount Taranaki on the country's North Island, hiking on the island's many volcanoes.
