For humans, the gestation period can last forty weeks. There are cramps, morning sickness, strange food cravings, increasing discomfort, and a multitude of other effects. And the nine months of pregnancy is often just a prelude to the real drama. All this pain and suffering is for a good reason though.Scientists are still learning more about when live birth evolved, but one fossil discovery in the South China Sea revealed a 250 million-year-old creature with an embryo in its ribcage. The Dinocep ...read more
Elephants are no pushovers when it comes to walking great distances every day, and they even seem to have a knack for planning their demanding journeys. A new study puts the ingenuity of these mammals on full display, showing how they strategically choose certain routes to make their trips as efficient as possible. The study, published in the Journal of Animal Ecology, shares several key findings that demonstrate how African savanna elephants move through challenging landscapes. Being the large ...read more
Within glacial ice sheets, there are streams of ice, sometimes called ice rivers, that move much faster than the surrounding ice. If you’re having trouble imagining how ice moves inside ice, Elizabeth Thomas, a paleoclimatologist at the University at Buffalo, suggests an analogy to help visualize these icebound rivers.Since the Gulf Stream carries warm water from the tropical Atlantic Ocean up the coast of the Carolinas and then across to Europe, she explains, “the Gulf Stream is essentially ...read more
Mosquitoes are more than pests. They’re also a mortal threat, contributing to millions of cases of malaria a year. Fortunately for humans, however, a team of researchers has recently identified a medication that could curb mosquito populations, controlling their spread of malaria. Revealing their results in a paper published in Science Translational Medicine, the researchers report that the medication nitisinone makes human blood deadly to mosquitoes. “One way to stop the spread of diseases ...read more
Humanity’s search for life on Mars has taken a significant step forward with the discovery of organic molecules that resemble key building blocks of life on Earth.Since landing in 2012, NASA’s Curiosity rover has made multiple discoveries suggesting that Mars may have once had habitable conditions. Now, scientists have identified the longest organic molecules ever found on the Red Planet — offering new insights into its potential to support life.A detailed report on these findings was rece ...read more
