Your dog doesn't need to drink orange juice. There are evolutionary and biochemical reasons why humans need to consume vitamin C but dogs -- and many other animals -- do not.
A new study looks at how eating habits are passed along generation to generation, and species to species. Humans are the rare exception, eating from both the meat and plant side of the buffet.
Here's what we have this time: Is evolution a "struggle" or "snuggle" for survival? ... Any profound loss, in this case of a father, ripples across our lives like a pebble on a lake. ... Physicians are often asked for advice. But do people want instructions or coaching? ... Finally, "mindful" consideration of one of the true vital signs: the breath.
Here's what's on tap: a video on the Top 5 poisons from the American Chemical Society; a look at how Darwin's theory keeps evolving; and Boeing's 737Max is a safety problem that's now becoming a big economic issue (and who do you think will be picking up that tab?) And finally, the Cosmic Crisp (pictured) coming to your grocery this fall.
A study of chicken bones helps tell the story of our Anthropocene times, which is when Sapiens began making a significant impact on the planet. What lessons can we learn from how we have, so significantly, altered a bird to fit our needs?
Raccoons certainly exhibit behaviors of both domesticated animals. On the one hand, like dogs, they live in packs. But not always. Raccoons (especially males) go through a phase when they live alone, just like most cats. But actually, this is a trick question. They're more like bears!
Researchers describe wild cattle on Amsterdam Island in the southern Indian Ocean, ones that lost about 25% of their body size in just over 100 years.
A phylogenetic and epidemiological analysis suggests that people who died from Ebola possibly spread the virus to more people than those who survived.
The relative size of the human male's penis and testes can be reduced to our species' mating strategies, and can provide some surprising insights into early human culture.
Parasitism evolved at least 223 times, far more than the previous estimate of 60. It arose more times in certain phyla (e.g., arthropods, nematodes, flatworms, and mollusks) than in others. Today, about half of all animal species are parasitic.
As a society, we never grew up beyond high school. Not being smart continues to be cool. Rejecting the collective wisdom of scientists, economists, academics, and journalists is applauded. Spurning the "establishment" has become the new national pastime.
