A researcher is suggesting changes to fur trapping practices to help prevent the accidental amputation of grizzly bear toes. The research is calling attention to a small number of grizzly bears in the southeast corner of British Columbia missing toes on their front paws.
‘Dangerous’ and ‘extremely dangerous’ heat stress to become more common by 2100
Even if countries manage to meet the Paris Agreement goal of keeping global warming to 2 degrees Celsius, combinations of heat and humidity that are dangerous to humans will become more frequent by 2100. A new statistical analysis finds that the tropics could be exposed to dangerous levels of heat...
New research tracks the history of manatees across Earth’s oceans
While only four species of slow-moving aquatic herbivores of the order Sirenia remain on Earth, many different kinds of sea cows lived over the past 47 million years. Sea cows have lived along the coasts of every continent but Antarctica, and at times numerous species coexisted. A new article has...
Scientists develop new technique to reveal the hidden genome
Thousands of short RNA sequences that code for microproteins and peptides have been identified, opening new avenues for disease research and drug development.
Climate change exacerbated hurricane Harvey’s flood damage, hitting low-income and Latinx neighborhoods disproportionately harder
New research shows that if it were not for the impact of climate change, up to 50 percent of residences in Houston's Harris County would likely not have been flooded by Hurricane Harvey five years ago. The study coincides with the fifth anniversary of Hurricane Harvey, a Category 4 hurricane...
Dogs with more active owners may get more exercise
A new, international study suggests that dog owners who spend more time exercising themselves tend to exercise their dogs more, and more active owners are also more likely to perceive their dog's body weight as being ideal.
Sawfish fossils suggest teeth likely evolved from body scales in ancient fish
Scientists have long debated the origins of teeth. Did they evolve from body scales that migrated into the mouths of ancient vertebrates and became adapted for eating -- an idea known as the 'outside-in' hypothesis? Or did they evolve independent of scales, originating deep within the oral cavity and ultimately...
Fossils of giant sea lizard that ruled the oceans 66 million years ago discovered
Fossils of a giant killer mosasaur have been discovered, along with the fossilized remains of its prey.
Sahelanthropus, the oldest representative of humanity, was indeed bipedal…but that’s not all!
The modalities and date of emergence of bipedalism remain bitterly debated, in particular because of a small number of very old human fossils. Sahelanthropus tchadensis, discovered in 2001 in Chad, is considered to be the oldest representative of the humankind. The shape of its cranium suggests a bipedal station. The...
Completing the micronutrient picture for plant-based milk alternatives
Plant-based milk alternatives are an attractive option for people with allergies or intolerances, or who prefer a dairy-free diet. However, because some essential minerals are required to be on the Nutrition Facts label only under certain circumstances, consumers might not know if they are meeting their dietary needs. Now, researchers...
