New research reveals that discrepancies between the locations where fossils are found and the areas where early humans are thought to have resided could affect our comprehension of human evolutionary history.A significant portion of the early human fossil record comes from a few key locations in Africa, where ideal geological conditions have preserved a wealth of fossils that scientists use to piece together the story of human evolution. One notable area is the eastern branch of the East African Rift System, which includes important fossil sites like Oldupai Gorge in Tanzania.Yet, the eastern branch of the rift system only accounts...

Explanation: When the dark shadow of the Moon raced across North America on April 8, sky watchers along the shadow's narrow central path were treated to a total solar eclipse. During the New Moon's shadow play diamonds glistened twice in the eclipse-darkened skies. The transient celestial jewels appeared immediately before and after the total eclipse phase. That's when the rays of a vanishing and then emerging sliver of solar disk are just visible behind the silhouetted Moon's edge, creating the appearance of a shiny diamond set in a dark ring. This dramatic timelapse composite from north-central Arkansas captures both diamond...

Ladies, if you’re hitting up a Chipotle in Fort Myers, Florida you might want to reconsider sending your husband to pick up the order. There’s allegedly a husband stealing employee at one of the locations. According to several Yelp reviews there’s a woman by the name of Lucy who likes to seduce married men. The controversy appears to have started last month when the first review warning women of the husband stealing employee popped up. The warning was not the only one. There were several all pointing the finger at a mystery employee named Lucy, who allegedly has a thing...

Recreating the musculature of the leg and pelvis, the imagery supports the supposition that this part-time tree-dwelling hominin walked completely erect, like humans, but more than three million years earlier.Starting with human MRI and CT scans to map muscle pathways, Wiseman next focused on virtual reconstructions of Lucy's bones and joints, and then married up cues from muscle "scarring" on the bones.The resulting model shows how Lucy was capable of upright, erect locomotion but also possessed powerful leg muscles that facilitated her species' half-land, half-arboreal lifestyle. Researchers believe the extra muscle power in the legs – 74% of the total...

New evidence suggests that the famous fossilised human ancestor dubbed "Lucy" by scientists died falling from a great height - probably out of a tree. CT scans have shown injuries to her bones similar to those suffered by modern humans in similar falls. The 3.2 million-year-old hominin was found on a treed flood plain, making a branch her most likely final perch. It bolsters the view that her species - Australopithecus afarensis - spent at least some of its life in the trees.

Artist’s concept of NASA’s Lucy spacecraft at an asteroid. Credit: NASA NASA’s Lucy spacecraft will add another asteroid encounter to its 4-billion-mile journey. On November 1, 2023, Lucy will get a close-up view of a small main-belt asteroid to conduct an engineering test of the spacecraft’s innovative asteroid-tracking navigation system. The Lucy mission is already breaking records by planning to visit nine asteroids during its 12-year tour of the Jupiter Trojan asteroids, which orbit the Sun at the same distance as Jupiter. Originally, Lucy was not scheduled to get a close-up view of any asteroids until 2025, when it will...

A dating method developed by a Purdue University geologist just pushed the age of some of these fossils found at the site of Sterkfontein Caves back more than a million years. This would make them even older than Dinkinesh, also called Lucy, the world's most famous Australopithecus fossil.

Manchin and fellow moderate Sen. Kyrsten Sinema (D-Ariz) have been in negotiations with Sanders and other progressive democrats for weeks over the price tag of the spending package. As Democrats go back and forth on the price tag of the spending bill, they are also discussing what to include in the legislation. The party could finalize the framework as early as this week.

NASA has tested the functions of Lucy, the agency’s first spacecraft to study Jupiter’s Trojan asteroids, filled it with fuel, and is preparing to pack it into a capsule for launch Saturday, October 16, 2021. Named after characters in Greek mythology, these asteroids circle the Sun in two swarms, with one group leading ahead of Jupiter in its path, the other trailing behind it. Lucy will be the first spacecraft to visit these asteroids. By studying these asteroids up close, scientists hope to hone their theories on how our solar system’s planets formed 4.5 billion years ago and why they...

Mammals from mice to monkeys have tails. But humans and our cousins the great apes lack them. Now, Researchers may have unearthed a simple genetic change that led to our abbreviated back end: an itinerant piece of DNA that leapt into a new chromosomal home and changed how great apes make a key developmental protein. The finding also suggests the genetic shift came with a less visible and more dangerous effect: a higher risk of birth defects involving the developing spinal cord. The work not only addresses an “inherently interesting question about what makes us human,” says Hopi Hoekstra, an...

`Linus and Lucy’ and other music he created for the Charlie Brown TV Specials reverberate forever in the American heart It’s great music to hear anytime, but especially this time of year. It’s the late jazz composer Vince Guaraldi’s joyful music for the Charlie Brown TV specials. His song, “Linus and Lucy” has become the main theme of all the Charlie Brown specials, though it was first used in the Charlie Brown Christmas special. Nobody had ever used a soundtrack of hip piano jazz for an animated feature before this. Composers such as the great Carl Stalling did compose tremendously...

VIRGINIA BEACH, Va. (WAVY) — Lucy, the infamous street savvy pup that has eluded capture for two years, is now in the custody of Virginia Beach Animal Control. Lucy first made headlines, and paused traffic, more than a year ago when Virginia Beach residents insisted, against city officials, on feeding the dog in the busy roadways of Lynnhaven Parkway and Sabre Street. From treats, toys, and kindness from Virginia Beach Animal Control officers, Lucy resisted all attempts of being caught in favor of the feasts passersby tossed at her. Officials said that while they understood the good intentions of the...

Research at Schengen demonstrates that already 300,000 years ago Homo heidelbergensis used a combination of throwing sticks, spears and thrusting lances. Prof. Nicholas Conard and Dr. Jordi Serangeli, who lead the research team, attribute the exceptional discovery to the outstanding preservation of wooden artifacts in the water saturated lakeside sediments in Schengen. The throwing stick was recovered in layer 13 II-4, which in the 1990s yielded examples of throwing spears, a thrusting lance and additional wooden tools of unknown function. Like almost all of these finds, the new artifact was carefully carved from spruce wood. The throwing stick is 64.5...

When the ancestors of modern humans left Africa 50,000 years ago they met the Neandertals. In this encounter, the Neandertal population contributed around two percent of the genome to present day non-African populations. A collaboration of scientists from Aarhus University in Denmark, deCODE Genetics in Iceland, and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have conducted the most comprehensive study to date using data obtained from 27,566 Icelanders, to figure out which parts of our genomes contain Neandertal DNA and what role it plays in modern humans. Every person of non-African decent shares around two percent of...

When it comes to deciphering our ancient family tree, DNA from fossils is the new gold standard. But after about half a million years, even the best-preserved DNA degrades into illegibility, leaving the story of our early evolution shrouded in mystery. A new study of proteins taken from the tooth of an enigmatic human ancestor reveals their rough place in the family tree -- and shows how ancient proteins can push beyond the limits of DNA. The new study is "a landmark paper," says Mark Collard, an archaeologist at Simon Fraser University who wasn't involved with the work. "Ancient protein...

The teeth, found in Germany, provoked one observer to suggest human history may need to be rewritten. Some experts, however, remain very skeptical. In a paper shared at the social networking site ResearchGate, Herbert Lutz and his team say they discovered “a new great ape with startling resemblances to African members of the hominin tribe.” The "plausible age” of the fossils — an upper left canine tooth and an upper right first molar — is 9.7 million years, they say. If confirmed, that would make the teeth around 6 million years older than fossils for the early-human, African ancestor Australopithecus...

Former Nevada Democrat state Sen. Lucy Flores accused former Vice President Joe Biden of sexual misconduct in a piece she wrote about a 2014 encounter she had with him that left her "mortified," saying she had "never experienced anything so blatantly inappropriate and unnerving before." Flores, a former member of Bernie Sanders’ political group Our Revolution, says that the incident happened as she was about to go on for a rally just days before the upcoming elections were held. "Just before the speeches, we were ushered to the side of the stage where we were lined up by order of...

The find, made in 110-million-year-old deposits in northwest China, is of a new species known as Avimaia schweitzerae and the fossil has been described as "incredibly well preserved." The new species belongs to the group known as Enantiornithes, which were fairly common in the Cretaceous period, living alongside dinosaurs. However, the fossilized egg may have resulted in the death of the so-called mother bird, researchers said. "The egg shell consists of two layers instead of one as in normal healthy bird eggs, indicating the egg was retained too long inside the abdomen," Dr. Alida Bailleul said in comments obtained by...
