Wildlife crossings over (and under) the highways could make animals (both wild and domesticated) and people safer. Our expanding network of roads is interrupting and fragmenting the territories of wild (and also domesticated) animals who need to cross our roads in search of food, water, mates, and shelter. Many are routinely struck and killed by …

Almost every human condition can be linked back to your genes. The list of genetic conditions is lengthy. Diseases like muscular dystrophy, Crohn’s disease, birth defects like spina bifida, and some cancers just barely scrape the long list of ailments that can be passed from one generation to the next. And, it seems that many …
Walking on two legs is an evolutionary leap that led humans to conquer the world. But, why humans are walking on two legs? It’s still unclear. Now, according to a new study published in the University of Chicago’s Journal of Geology, the reason might be exploding stars a few million years ago.
We, humans, are destroying the Earth’s wilderness, very fast. Actually, we are the main (and probably the only) cause of the sixth major extinction event in the history of our planet. Now, a recent UN report says at least one million species (animals, plants, and insects) are at the risk of extinction. There will be …

According to a new study published in the May 2, 2019 issue of Nature, 4.6 billion years ago, two neutron stars collided near the early Solar System (actually about 1000 light-years from the gas cloud that eventually formed the Solar System). This violent collision has created heavy elements like silver, gold, platinum, cesium, and uranium. …

NASA’s Global Ecosystem Dynamics Investigation (GEDI) on the International Space Station (ISS) beams laser light down to Earth to reveal the height and density of trees and vegetation.
Even if we stop destroying Earth’s wilderness today, it would take 3 to 5 million years for Earth to recover from the 6th mass extinction, scientists warn.
The blue whale (scientific name: Balaenoptera musculus) is a marine mammal belonging to the baleen whales (Mysticeti). Up to 31 meters (102 feet) in length and 190 tonnes (210 short tons) in weight, it is the largest extant animal and also is the heaviest known to have existed. But it’s hard to conceptualize how big …

Around 55.5 million years ago, there was a time period with more than 5°C – 8 °C warmer global average temperature than today, which named “Paleocene-Eocene Thermal Maximum” (PETM). As a result, there were crocodiles and even crocodiles in the Arctic and the region was completely ice-free. Now, a new study suggests that if we …
I recently saw a question on Quora and it was like that: “Why is it called the ‘theory of evolution’ but the ‘law of gravity’?” This question is strongly related to a common misconception about evolution: “It is just a theory” – creationists always say “Evolution is just a theory”.
