McGill University in the news //www.puressens.com/ en-us provides the latest news from McGill University Tiny bodies of bats allow perfect balance between flight costs and heat dissipation Many mammal species living in cold climates tend to have large bodies and short limbs to reduce heat loss—a general pattern known as Bergmann's rule. However, bats are the exception to the rule, displaying small body sizes in both hot and cold regions.https://phys.org/news/2022-07-tiny-bodies-flight-dissipation.html Plants & Animals Thu, 21 Jul 2022 13:08:03 EDT news577627681 No pain, no gain? How the brain chooses between pain and profit Imagine having to choose over and over between what you enjoy doing and the pain that it might cause you, whether physical or emotional. If you live with conditions such as depression, anxiety, or chronic pain, you are probably familiar with making these difficult choices on a daily or weekly basis. But surprisingly little is known about which areas of the brain are involved in decisions of this kind.//www.puressens.com/news/2022-07-pain-gain-brain-profit.html Psychology & Psychiatry Wed, 20 Jul 2022 12:44:03 EDT news577539841 Which rules evolutionary change: Life or climate? 化石记录过去十亿是的rs shows biodiversity as a zigzagging pattern of species births and extinctions. For decades scientist have attempted to answer the question: Which rules supreme—life or the environment? To explain this macroevolution, scientists have used two opposing theories: the Red Queen versus the Court Jester theory, inspired by the story Alice in Wonderland. New research by McGill University and Vilnius University puts these two theories to the test.https://phys.org/news/2022-07-evolutionary-life-climate.html Evolution Fri, 01 Jul 2022 03:46:34 EDT news575865945 A gentler, more precise laser cutting technique Laser cutting techniques are usually powered by high energy beams, so hot that they melt most materials.

As a result, efforts to reduce poverty were adopted in Canada and the United States. But how did partisan politics shape each government's response? Exploring the political dynamics at play, a team of researchers including McGill University Professor Daniel Béland, traces the adoption and evolution of anti-poverty measures in both countries.https://phys.org/news/2022-07-covid-poverty-reduction-agenda.html Social Sciences Fri, 01 Jul 2022 03:21:18 EDT news575864469 A blueprint for life forms on Mars? The extremely salty, very cold, and almost oxygen-free environment under the permafrost of Lost Hammer Spring in Canada's High Arctic is the one that most closely resembles certain areas on Mars. So, if you want to learn more about the kinds of life forms that could once have existed—or may still exist—on Mars, this is a good place to look. After much searching under extremely difficult conditions, McGill University researchers have found microbes that have never been identified before. Moreover, by using state-of-the-art genomic techniques, they have gained insight into their metabolisms.https://phys.org/news/2022-06-blueprint-life-mars.html Astrobiology Tue, 21 Jun 2022 13:33:12 EDT news575037190 Melanoma map shows skin cancer is on the rise in Canada Rates of melanoma, a deadly form of skin cancer, are on the rise in Canada.

It allows the seeds of this parasitic plant to stick to and infect host plants. Since ancient times, mistletoe berries have been explored as treatments for everything from infertility and epilepsy to cancer. But, until now, no one has fully investigated the potential medical or technical uses of the glue itself. A recent paper from McGill University and the Max Planck Institute of Colloids and Interfaces, published in PNAS Nexus, suggests that through simple processing, viscin's ultra-stiff flexible fibers, which adhere to both skin and cartilage as well as to various synthetic materials, could have a range of applications—both biomedical and beyond.https://phys.org/news/2022-06-mistletoe-berries-secret-biological-super.html Materials Science Tue, 14 Jun 2022 14:49:37 EDT news574436975 Air pollution gets worse during winter at airports 空气污染造成大约700万人死亡every year worldwide. According to researchers from McGill University, airports are hotspots for airborne pollutants that are detrimental to human health and the Earth's climate. Studying air pollution at three major Canadian airports the researchers found that airports situated in colder climates accumulated more pollutants like PM2.5 in the fall and winter, compared to airports in milder climates. The smallest and the coldest airport with the least number of flights and passengers had the highest PM2.5 concentration.https://phys.org/news/2022-06-air-pollution-worse-winter-airports.html Environment Thu, 09 Jun 2022 12:19:42 EDT news573995980 Gender gap: Women leaders face more scrutiny than male counterparts More than ever before, women are reaching new heights in various fields.

The lack of an effective drug treatment for hospitalized patients with severe COVID-19 has contributed to the more than six million deaths worldwide since the beginning of the pandemic, including more than 50,000 deaths in May 2022 alone. To address this therapeutic gap, a team of researchers from the Research Institute of the McGill University Health Center (RI-MUHC), the Canadian Center for Computational Genomics (C3G), and the McGill Genome Center studied host biological responses of patients hospitalized with severe COVID-19, looking for differences between patients who recovered and those who succumbed to the disease.//www.puressens.com/news/2022-06-drugs-mortality-severely-ill-covid-.html Medications Thu, 09 Jun 2022 10:12:57 EDT news573988372 The secret lives of Darwin's finches reveal daily commutes equal to the area of 30 soccer fields Using radio transmitters, scientists have gained new insights into the behavior of medium ground finches in the Galapagos Islands.

The concept of folding has been used to build reconfigurable structures, which change their function by changing their shape. These structures are promising for applications such as nanorobots for drug delivery, foldable solar panels for aerospace, and morphable cladding and shading for architecture. However, most of these designs cannot bear heavy loads. Those that can are only able to do so in a certain direction, collapsing along the direction in which they fold. This limits their use as structural materials.https://phys.org/news/2022-05-origami-kirigami-reconfigurable-materials.html Materials Science Wed, 25 May 2022 02:29:42 EDT news572664579 Why are male mice afraid of bananas?

You are not alone. McGill University researchers may have found a solution based on "nudges," small changes to phone settings or behavior that can help curb smartphone addiction. The intervention includes various components such as changing the phone display to greyscale and keeping the phone out of the bedroom when sleeping. The researchers found that participants following the intervention reduced their screen time, reported feeling less addicted to their phones, and had better sleep quality.https://techxplore.com/news/2022-05-nudges-people-curb-smartphone-addiction.html Consumer & Gadgets Thu, 19 May 2022 13:49:41 EDT news572186978 Unlocking the secrets of killer whale diets and their role in climate change 虎鲸的数量正在入侵的北极,causing significant disruptions to an ecosystem already deeply affected by climate change.

Especially if it happens regularly. An increasing number of studies have shown an association between food insecurity and adverse mental health outcomes. Now, new research from McGill University has looked at the impacts of food insecurity on the mental health of both parents and children separately. The researchers found that in families where adults sacrifice their own nutritional needs so that their offspring are fed first, the mental health of both groups is less severely affected. Although it is affected, nevertheless.//www.puressens.com/news/2022-05-shielding-children-food-insecurity-psychological.html Psychology & Psychiatry Wed, 04 May 2022 14:11:57 EDT news570892298 Hard to change minds when it comes to vaccine willingness In the fall of 2020, before vaccines were readily available, the Canadian Longitudinal Study on Aging (CLSA) surveyed nearly 24,000 middle-aged and older adults to test their willingness to get vaccinated.
