Tracking narwhal by their ‘fluke-prints,’ and how forgetting benefits the mind
Contemplating the emotional side of spaceflight
Bob McDonald's blog: Actor William Shatner's nakedly emotional response to his sub-orbital flight is a welcome reminder of the perspective-changing potential of a trip to space.
Fecal transplants from young mice are like a 'fountain of youth' for old mice, study finds
It might not be the fountain of youth we've dreamed of, but experiments in mice suggest one possible, if distasteful, path to rejuvenation: a dose of the microbial ecosystem from the gut of a healthy youngster.
How a trick of the light helps scientists spot the same supernova again and again
10 billion years ago, a star exploded. And because of a strange optical phenomenon in which a galaxy can bend and magnify the explosion's light, the Hubble Telescope managed to capture the supernova three separate times.
Dancing bees reveal that U.K. cities offer more accessible food than the countryside
In a new study, researchers decoded honeybees' waggle dances to determine how far they have to travel to find food. Bees in agricultural areas have to travel twice as far as those living in the 'concrete jungle' of downtown London, according to the research.
Narwhals leave infrared 'fluke-prints' in the ocean that can be seen with aerial cameras
Researchers accidentally discovered a method that will allow them to track the elusive whales
A memory researcher explores the science — and value — of forgetting
Dr. Scott Small's new book suggests forgetting is a key to human cognition and happiness.

Are celebrity tourists eclipsing the real science done in space?
Captain Kirk may really be going to space, but he's not doing the real exploration, writes Quirks & Quarks host Bob McDonald.
We know humans are behind climate change, thanks to this Nobel Physics laureate's work
Klaus Hasselmann is one of the 3 recipients of the Nobel Prize in Physics. His work helped us better understand the complex physics of climate change.
New Nobel laureate in chemistry reflects on how his discovery catalyzed his field
This year’s Nobel Prize in Chemistry went jointly to David MacMillan and Benjamin List, who developed an efficient, affordable way to create new molecules, which has been called a "game changer" for the field of chemistry.
Researchers investigate an 'ultra-hot Jupiter' with iron rain and calcium wind
640 light years away, the planet is larger than Jupiter but orbits closer to its sun than Mercury
Canadian concept to pump carbon into subsea rock could sequester gigatons of CO2
‘There’s so much more capacity in these aquifers than is actually needed to deal with the problem.’
Cloud-based sunscreen could help protect the Great Barrier Reef from future heat damage
Scientists in Australia have been testing a system for artificially brightening clouds to reflect more of the sun's energy
How watching water bears walk could help us make small and squishy robots
Usually, soft microscopic animals like the tardigrade don’t walk - they roll, or swim, or slither. In a new study, researchers are trying to understand more about the way these animals move.

NASA targets the moon's South Pole for a rover mission
Bob McDonald's blog: NASA's VIPER rover will scout for water ice in craters where the sun doesn't shine.
Indigenous archeology and finding the 'children who never came home'
Kisha Supernant, director of the Institute of Prairie and Indigenous archeology at the University of Alberta says archeological expertise can be a critical tool in the search for unmarked graves at residential school sites.
Ice age footprints suggest North America's first peoples were here earlier than we thought
The recent discovery of human footprints in New Mexico that date back to 23,000 years ago could mean that humans inhabited the Americas well before the end of the last ice age.
Monkeys respond to high pressure situations by choking, just like humans do
When jackpot-sized rewards were on the line, the monkeys became too cautious and their performance in a learned task declined
Set weapons to sautée: Engineers use lasers to cook 3D-printed chicken
In an experiment cooking 3D-printed chicken, laser-cooked food retained moisture and tasted better — at least according to a study by engineers at Columbia University.
Vampire bats share blood meals with their besties
Researchers have discovered vampire bats meeting up to share a meal while foraging, a behaviour that is shedding light on social relationships and cooperation in the animal kingdom.
