Booming trade in mammoth ivory may be bad news for elephants

TORONTO— In 2015, Andy Huynh was accompanying wildlife guards in Kenya’s Maasai Mara National Reserve to help ward off poachers. Fresh off a decade of service in the Middle East with U.S. Special Operations Forces, he thought there was little that could faze him. But when he saw his first poached rhinoceros, with half of its face sawed away for the horn, he turned and...

Rats bop to the beat

Accurately moving to a musical beat was thought to be a skill innately unique to humans. However, new research now shows that rats also have this ability. The optimal tempo for nodding along was found to depend on the time constant in the brain (the speed at which our brains can respond to something) which is similar across all species. This means that the ability of our auditory and motor systems...

Popular dietary supplement causes cancer risk, brain metastasis

While previous studies have linked commercial dietary supplements like nicotinamide riboside (NR), a form of vitamin B3, to benefits related to cardiovascular, metabolic and neurological health, new research has found NR could actually increase the risk of serious disease, including developing cancer. The international team of researchers discovered high levels of NR could not only increase...

Divers Discover a Long-Lost Piece of the Shuttle Challenger

It was more than 36 years ago that NASA suffered one of its greatest tragedies, when the space shuttle Challenger exploded 73 seconds after liftoff on a cold January morning in 1986. Yesterday, NASA reported that a piece of debris from Challenger was found off the coast of Florida by a team of divers who were filming a documentary on the loss of World War II era aircraft in the same area....

NASA’s Mega-Moon Rocket Survives a Hurricane

If you owned a 32-story, 2.6 million kg (5.7 million lb), $4.1 billion moon rocket, the last thing you’d think you’d want to do is leave it out in a hurricane. Well, NASA does own a 32-story, 2.6 million kg, $4.1 billion moon rocket and leaving it out in a hurricane is just what the agency did yesterday—mostly because that turned out to be the best and safest of a bad lot of...

Slaves to the rhythm: rats can’t resist a good beat, researchers say

Study finds rats instinctively move in time to music – an ability previously thought to be uniquely humanMusic makes you lose control, Missy Elliott once sang on a hit that is almost impossible to hear without bopping along. Now scientists have discovered that rats also find rhythmic beats irresistible, showing how they instinctively move in time to music.This ability was previously thought to...

How racism skewed estimates of heart disease in women

Growing up as a multiracial person in the United States, Alexis Reeves was no stranger to the impact of racial discrimination. She spent summer vacations with her father’s family in Pennsylvania, where her Black grandfather had worked as a sharecropper. Nearly everyone on that side of her family had high blood pressure, took cholesterol medication, or had experienced some form of heart...

In search of the perfect match schedule

Sports and competition are inextricably linked. But producing the optimal match schedule is a sport in itself. Mathematician Roel Lambers studied ways to ensure that darts players and teams playing either soccer or a Dutch regional sport called beugelen are matched up as fairly as possible. He defended his thesis on Friday November 11th at the Department of Mathematics and Computer Science.
