The surprising complexity behind the squeak of basketball shoes on hardwood floors

NEW YORK (AP) — As he watched the Boston Celtics play from the stands of TD Garden, one noise kept catching Adel Djellouli's ear.

“This squeaking sound when players are sliding on the floor is omnipresent,” he said. “It’s always there, right?”

Squeaky shoes are part of the symphony of a basketball game, when rubber soles rasp against the hardwood floors as players jab step, cut and pivot and defenders move their feet to stay in front of their assignment.

Returning home from the game, Djellouli wondered how that sound was produced. And as a materials scientist at Harvard University, he had a way to find out.

Social media companies face legal reckoning over mental health harms to children

For years, social media companies have disputed allegations that they harm children’s mental health through deliberate design choices that addict kids to their platforms and fail to protect them from sexual predators and dangerous content. Now, these tech giants are getting a chance to make their case in courtrooms around the country, including before a jury for the first time.

Some of the biggest players from Meta to TikTok are facing federal and state trials that seek to hold them responsible for harming children's mental health. The lawsuits have come from school districts, local, state and the federal government as well as thousands of families.

Two trials are now underway in Los Angeles and in New Mexico, with more to come. The courtroom showdowns are the culmination of years of scrutiny of the platforms over child safety, and whether deliberate design choices make them addictive and serve up content that leads to depression, eating disorders or suicide.

Experts see the reckoning as reminiscent of cases against tobacco and opioid markets, and the plaintiffs hope that social media platforms will see similar outcomes as cigarette makers and drug companies, pharmacies and distributors.

Fossilized vomit provides insight on predator that lived 290 million years ago

BRANDON — A Brandon University paleontologist has helped identify prehistoric barf that’s nearly 290 million years old — and could be the oldest known example of fossilized vomit from a land-dwelling predator.

Mark MacDougall, an assistant biology professor, was part of a research team that identified 41 bones from at least three animals inside the regurgitated cluster by using CT scans and chemical analysis, the university said in a news release.

Signs point to the vomit coming from a top predator — likely an early relative of mammals — that gulped down a mixed meal that included a small reptile, a fast-moving lizard-like animal and part of a much larger plant-eater, and later coughed it back up.

“It’s rare to get such direct evidence of who was eating whom nearly 300 million years ago,” said MacDougall, co-author of the international study published last month in the journal Scientific Reports.

Manitoba to screen infants for defect that causes sight, hearing problems

Manitoba has become the third jurisdiction in Canada to implement universal newborn screening for congenital cytomegalovirus, which can lead to complications as a child grows up, including hearing loss, vision problems and developmental disabilities.

The delicate art of pressing flowers

When early explorers travelled the four corners of the world in search of botanical treasures and plant knowledge, they faced many challenges collecting and transporting live plant material. In the 19th century, the development of the Wardian case — a glazed box that held soil and water — enhanced the survival rate of live plants on long sea journeys.

But highly detailed botanical illustrations also served as a visual record for early botanists and scientists to study plants from distant parts of the world. The technique of pressing and drying all the parts of individual plants on paper made it possible to preserve plant specimens.

Today, herbariums around the world, including those at Manitoba Museum and the University of Manitoba, house extensive collections of pressed, dried plants stored in specialized, climate-controlled conditions. Scientists use these specimens to determine the rarity of species and understand environmental changes.

U of M partners with firm behind proposed sand mine to study Manitoba groundwater

University of Manitoba researchers will soon have a new, non-invasive tool to study the province’s vast groundwater resources after inking a partnership with Alberta-based mining company Sio Silica.

“If the technology works … it’s going to provide a mechanism to do real-time monitoring of changes in groundwater,” Ricardo Mantilla, an associate professor in the university’s civil engineering department and lead researcher for the project, said in an interview.

The emerging technology — called absolute quantum gravimetry — can measure changes in gravity caused by changes in groundwater levels, allowing researchers to better understand the flow and storage of underground water resources without the need for “expensive and disruptive” drilling, he said.

“That obviously has applications for (Sio Silica), but it can have very important implications for how we understand groundwater in aquifers in our province.”

U of M research underscores importance of polar bears to future of Arctic

Polar bears are generous hunters whose leftovers feed many other animals, new research shows, casting the protected species as a major provider, not just a vulnerable predator in a province that attracts thousands of polar bear watchers every fall.

Arctic foxes, wolverines, eagles, hawks, gulls and even younger bears are among at least 11 species who feast on the prey left behind by polar bears. The latest study calculates the leftovers: 7.6 million kilograms per year in picked-over seal carcasses left on sea ice.

That’s a conservative estimate, said biologist and University of Manitoba PhD candidate Holly Gamblin, lead author of the study published Tuesday in the journal Oikos from the Nordic Ecological Society.

“A bunch of my co-authors are in that polar bear research world and have been thinking about investigating (this issue), knowing that it’s this really under-represented and under-studied component of the story, when we think about polar bears as apex predators,” said Gamblin, who has studied Arctic foxes. “They had had this idea for a while and I was just sort of in the right place at the right time.”

Winnipeg-based organization injects federal funds into innovative, women-powered business in Bolivia

With practised grace, Antonia Olpo slides down the bank of the long, shallow pond and plunges fully clothed into the muddy water. On the grass above, other women and their male helpers unfurl the net, stretching it across the pond from edge to edge, and let it sink below the surface.

American Eagle counts new customers after Sydney Sweeney ad frenzy and shares soar

Shares of American Eagle Outfitters spiked 34% Thursday after the teen clothing retailer said the frenzy surrounding its Sydney Sweeney ad campaign drew new customers during its most recent quarter.

American Eagle rolled out its new new ad campaign starring 27-year-old actor over the summer. The fall denim campaign sparked a debate about race, Western beauty standards, and the backlash to “woke” American politics and culture.

Negative reactions centered on ads that used the word “genes” instead of “jeans” featuring the blonde-haired, blue-eyed actor known for the HBO series “Euphoria” and “White Lotus.”

But American Eagle did get noticed, executives said late Wednesday in a call after the Pittsburgh retailer posted second quarter earnings.

There is no innovation without social accountability

“Can a country call itself innovative if its founding wounds remain open?” That’s a question I’ve been sitting with for a while.

Every Floridian should have a plan for this year’s hurricane season, DeSantis says

ORLANDO, Fla. (AP) — Two days away from the start of hurricane season, Florida Gov. Ron DeSantis and the state’s top emergency manager joked Friday that they didn't want to encounter each other again until the storm season ends in late November. Forecasts suggest that’s unlikely.

While the upcoming season, which starts Sunday, isn't expected to be as topsy-turvy as last season, the National Oceanic and Atmospheric Administration says there's a 60% chance it will be above normal, a 30% chance near normal and just a 10% chance it will be quieter than average. Relentless storms, including Debby, Helene and Milton, which landed in Florida last year, made for the third-costliest hurricane season on record last year.

“You just have to prepare and plan that we are going to have impacts,” DeSantis said at a news conference in front of shelves of generators at a Home Depot store in Jupiter, Florida. “If you plan and it doesn't happen, you're never going to have regrets. If you don't plan and it happens, you're going to immediately be saying, ‘Why didn’t I do this?'”

Ahead of any hurricanes headed toward the peninsula, Floridians should be prepared to have seven days of food, water and supplies for their households, including pets. If they need to evacuate, they don't have to travel hundreds of miles when traveling just a few miles inland to a hotel or shelter works, officials said.

Paleontologist makes strides toward understanding the way mosasaurs behaved

Maximilian Scott is a vertebrate paleontologist who focuses on extinct animal behaviour and behavioural evolution. Scott, 27, from Ovid, Mich., is in the last year of his master’s degree at the University of Manitoba studying mosasaurs, an ancient marine lizard that lived in Manitoba during the late-Cretaceous period.

He also offers tutoring in geology, biology, animal behaviour and conservation to people of all ages. You can find him on Instagram.

Our story doesn’t start with the first book that was written, our story starts a long time before that, a long time before the first humans. It’s all one long story.

Humans have only existed for 200,000 years. The Earth has been around for 4.5 billion years. Life has been around for three billion years, and complex life has been around for 542 million years.

Psychologist sues Shared Health, U of M

A psychologist recruited to care for sick youths claims she was “pressured to engage in misconduct and other violations of professional standards” and then fired without cause when she complained to the provincial regulator.

The allegations are detailed in a lawsuit filed this week against Shared Health and the University of Manitoba in Court of King’s Bench.

According to the lawsuit, Dr. Michelle Keiski lodged a complaint with the Psychological Association of Manitoba in September 2022 to raise the alarm over issues inside the Max Rady College of Medicine, including the misreporting of studies and data, and staff providing services they are not qualified to deliver.

Keiski, a clinical psychologist, was placed on administrative leave one month after filing the complaint and later terminated without cause, the lawsuit said.

U of M expands clinical psychology program to address Manitoba shortage

The University of Manitoba is expanding its clinical psychology program this fall in an effort to boost the number practising in the province, where the per capita rate is among the lowest in Canada.

The number of seats in the U of M’s masters and doctoral clinical psychology program has been increased to 12 for September, up from eight in previous years, with a plan to expand to 16 seats next fall.

“It’s going to mean better access to psychological care for Manitobans. It doesn’t seem like a big number … but really, we’re doubling our program,” said Kristin Reynolds, associate professor and clinical training director in the U of M’s psychology department.

“Where we now have 50 students in the program, from the first year of the masters to more senior years in doctoral studies, in the years to come, we’ll have more like 100.”
