Honeybees Join The Elite Group Of Animals That Understand The Concept Of Zero

Just a few decades ago, humans were the only species believed to be smart enough to grasp the concept of zero — the idea that nothing can be counted as something. While a select group of animals, including dolphins, primates, and a few birds, have since been added to the list, experts have always maintained that only “intelligent” species are capable of processing the difficult concept. Now, researchers from Melbourne’s RMIT University and France’s Université de Toulouse assert that honeybees, which like all insects are considered to be at the low end of the cognitive spectrum, also understand the abstract mathematical notion of nothing....

NASA's Parker Solar Probe Begins Historic Voyage To "Touch" The Sun

NASA’s ambitious mission to “touch” the Sun got underway at 3:31 a.m. EST on August 12 with the launch of the Parker Solar Probe from Cape Canaveral, Florida. Within six weeks, the spacecraft, which is currently traveling at 39,500 miles per hour, will conduct the first of seven flybys of Venus and use the planet’s gravitational pull to catapult itself closer to the Sun. The process, known as gravity assist, is instrumental in the probe’s mission to reach our fiery star....

Grieving Salish Sea Orca Whale Carries Dead Calf For 17 Days

While whales are known to grieve the loss of their loved ones, the recent story of an orca mom clinging to her dead calf for over two weeks demonstrates unprecedented evidence of the strength of the species’ familial bonds. The heart-wrenching saga began on July 24, 2018, after a female calf born to J35, aka Tahlequah — a member of the endangered Southern Residents Killer Whales (SRKW) pod — died 30 minutes after birth. Instead of letting the carcass sink into the ocean, the grieving mother began carrying the lifeless body by balancing it on her forehead or nudging it along the water surface with her nose....

Researchers May Have Finally Figured Out The Reason For Our Eyebrows

The most noticeable difference between the modern human face and that of the hunter-gatherers, who lived on Earth over 200,000 years ago, is the forehead. While we now have flat, smooth foreheads with visible eyebrows, our ancestors sported a pronounced brow ridge. Experts have always believed that the thick rim, and the evolution to the beautiful tufts of facial hair, served a physiological function. Now, a team of scientists from UK’s University of York and Portugal’s Universidade do Algarve suggest the distinct facial features help with our social relationships....

Alligators On The Beach? Killer Whales In The River? Get Used To It!

Large predators are increasingly appearing in unexpected places — alligators in saltwater marshes, killer whales in rivers, and mountain lions far away from the closest mountain. Experts hypothesize that as successful conservation efforts increase the local populations of these predators, they are moving beyond their usual habitats in search of food. However, Brian Silliman, professor of marine conservation biology at Duke University has a different theory. He believes the animals are recolonizing habitats they lived and hunted in for centuries — before human activity pushed them to the brink of extinction, and long before researchers began studying them....

14,000-Year-Old Charred Breadcrumbs Discovered In Jordan Prove Our Nomadic Ancestors Were Adept Bakers

Archeologists had always assumed that our early ancestors began baking about 10,000 years ago, after they gave up their nomadic way of life and became farmers. The scientists hypothesized that the abundant grain harvests inspired ancient humans to mill the crop into flour and make bread. However, the discovery of the charred remains of a flatbread that dates back over 14,000 years seems to indicate humans began baking long before their transition to an agricultural-based life....

Siberia's Pleistocene Park Adds Baby Bison In Quest To Restore Ice Age Ecosystem

If the recently released Jurassic World: Fallen Kingdom has you yearning to see the ancient creatures in real life, you are out of luck.

However, if Nikita and Sergey Zimov have their way, a prehistoric Ice Age ecosystem may soon become a reality. Their motive is not to attract tourists but to stop the thawing of the Arctic permafrost....

Video Assistant Referee And Other Neat Technologies In Play At The 2018 FIFA World Cup

Unlike other professional sports organizations such as the NBA, NFL, or MLB, FIFA, the governing body of association football, or soccer, has traditionally been resistant to adopting technology on the field. "We shall rely on human beings," former FIFA President Sepp Blatter said in 2002. "Players make mistakes, coaches make mistakes and yes, sometimes referees make mistakes. But football is passion, football is emotion. Football has a human touch."...

Hawaiians Brace For More Lava And Earthquakes As Kilauea Volcano Continues To Erupt

Though it is not uncommon for the Kilauea volcano on the southern shore of Hawaii’s Big Island to erupt, the recent explosion is the worst encountered in decades. The sea of lava, which has been flowing unabated since May 3, has encompassed 104 acres (the equivalent of 100 football fields), destroyed 35 structures — including 26 homes — and forced almost 2,000 people to evacuate. Unfortunately, even experts have no idea when the volcanic activity will subside....

Why American Retailers Love Mother's Day Almost As Much As Moms

On Sunday, May 13, most Americans will celebrate the extraordinary woman in their lives — Mom — with a perfect outing and a gift or two.

Even better? The spending keeps increasing year after year....
