Laurence Hurst: Is human evolution speeding up or slowing down? Your brain exaggerates memories to remember them better. Like a fisherman talking about the size of the one that got away, the brain exaggerates its memories.

They occur when a person either deliberately or unconsciously conceals a feeling. Seven emotions have universal signals: anger, fear, sadness, disgust, contempt, surprise and happiness. You can learn to spot them. History. Hominid and hominin – what’s the difference? New definitions The most commonly used recent definitions are: Hominid – the group consisting of all modern and extinct Great Apes (that is, modern humans, chimpanzees, gorillas and orang-utans plus all their immediate ancestors).
Hominin – the group consisting of modern humans, extinct human species and all our immediate ancestors (including members of the genera Homo, Australopithecus, Paranthropus and Ardipithecus). What’s in a Name? Hominid Versus Hominin. If you follow news about human evolution, you’ve probably noticed that our ancestors are increasingly called hominins rather than hominids.

Early human habitat, recreated for first time, shows life was no picnic: Pioneering Rutgers scientist helps reconstruct an ancient East African landscape where human ancestors lived 1.8 million years ago. Scientists have pieced together an early human habitat for the first time, and life was no picnic 1.8 million years ago.
Our human ancestors, who looked like a cross between apes and modern humans, had access to food, water and shady shelter at a site in Olduvai Gorge, Tanzania. They even had lots of stone tools with sharp edges, said Gail M. Ashley, a professor in the Rutgers Department of Earth and Planetary Sciences in the School of Arts and Sciences. Your brain might be hard-wired for altruism: Neuroscience research suggests an avenue for treating the empathically challenged. It's an age-old quandary: Are we born "noble savages" whose best intentions are corrupted by civilization, as the 18th century Swiss philosopher Jean-Jacques Rousseau contended?

World’s first gene-edited babies created in China, claims scientist. A scientist in China claims to have created the world’s first genetically edited babies, in a potentially ground-breaking and controversial medical first.
If true, it would be a profound leap of science and ethics. This kind of gene editing is banned in most countries as the technology is still experimental and DNA changes can pass to future generations, potentially with unforeseen side-effects. Johannes Rebmann. Johannes Rebmann (January 16, 1820 – October 4, 1876) was a German missionary and explorer credited with feats including being the first European, along with his colleague Johann Ludwig Krapf, to enter Africa from the Indian Ocean coast.
In addition, he was the first European to find Kilimanjaro. News of Rebmann's discovery was published in the Church Missionary Intelligencer in May 1849, but disregarded as mere fantasy for the next twelve years. The Geographical Society of London held that snow could not possibly occur let alone persist in such latitudes and considered the report to be the hallucination of a malaria-stricken missionary. It was only in 1861 that researchers began their efforts to measure Kilimanjaro. Expeditions to Tanzania between 1861 and 1865, led by the German Baron Karl Klaus von der Decken, confirmed Rebmann’s report.
Together with his colleague Johann Ludwig Krapf he also discovered Mt. Early life Watch Annals of Obsession. Andrew Zimmerman Jones: Does time exist? Ampullae of Lorenzini - an overview. Passive Electroreception in Different Aquatic Environments Several studies have revealed that the sensitivity of passive electroreception of low-frequency bioelectric fields emanating from prey may vary enormously in a range of different aquatic environments.
Canal length varies significantly in the ampullary organs of saltwater and freshwater vertebrates and is thought to be an adaptation for adjusting sensitivity. The long canals of elasmobranchs enable low-frequency electric fields to be virtually unattenuated because of the high resistance of the canal walls and the low resistance of the jelly core.

Orchid Bees Blend Their Own Perfume. Humans aren't the only ones that create intoxicating perfume blends, as new research finds that male orchid bees also practice this time-honored craft. The bees from the genus Euglossa formulate their unique perfumes for reasons similar to ours: to attract mates, establish a signature identity, and smell good in a crowd. They do this by gathering a variety of carefully selected scents from their environment, and then douse their bodies with the perfume. "The males expose them at the places where mating occurs," said co-author Thomas Eltz of Ruhr-University Bochum, "so the perfumes may be chemical signals to females. " Plant These Flowers to Power Bees: Photos For the study, published in the Journal of Experimental Biology, Eltz and his colleagues collected several species of orchid bees during a trip to Panama.

Carpenter bee - Wikipedia. Carpenter bees are species in the genus Xylocopa of the subfamily Xylocopinae. The genus includes some 500 species in 31 subgenera. Members of the related tribe Ceratinini sometimes are called "small carpenter bees". The common name "carpenter bee" derives from their nesting behavior; nearly all species burrow into hard plant material such as dead wood or bamboo.
