The Emergent Mind

WHAT GOES ON in the minds of babies? A lot, it turns out: long gone are the days when psychologists believed infants couldn’t use abstract thought. Recent research from the lab of Elizabeth Spelke, Berkman professor of psychology, suggests that babies can understand things about social behavior, preferences—even about people’s objectives and values. -The emergent mind, Harvard magazine

Τα φάρμακα στην αρχαιότητα

Η αναζήτηση των φαρμάκων άρχισε από το περιβάλλον. Όπως και τα ζώα, ο πρωτόγονος άνθρωπος είχε πολύ ανεπτυγμένο το ένστικτο αυτοπροστασίας. Σταδιακά κυριάρχησε η παρατήρηση και ο συσχετισμός των θεραπευτικών μέσων με συγκεκριμμένες ασθένειες. Αναμφίβολα και η τύχη βοήθησε στην ανακάλυψη των φαρμάκων._ Ε. Σκαλτσά

A surprising chill before the cosmic dawn

An experiment to estimate when stars began to form in the Universe suggests that gas temperatures just before stars appeared had fallen well below predicted limits, and that dark matter is not as shadowy as was thought._ Nature 555, 38-39 (2018)

The secret life of Higgs bosons

The Higgs boson has existed since the earliest moments of our universe. Its directionless field permeates all of space and entices transient particles to slow down and burgeon with mass. Without the Higgs field, there could be no stable structures; the universe would be cold, dark and lifeless.

Ancient DNA Tells Tales of Humans’ Migratory History

Fueled by advances in analyzing DNA from the bones of ancient humans, scientists have dramatically expanded the number of samples studied­­ – revealing vast and surprising migrations and genetic mixing of populations in our prehistoric past._hhmi

Φαινόμενο Dunning – Kruger: Η αυτοπεποίθηση των ανεπαρκών ανθρώπων.

Οι περισσότεροι άνθρωποι συνήθως είναι πολύ ικανοί σε ορισμένες δεξιότητες και σε κάποιες άλλες λιγότερο ικανοί (υπολείπονται). Ωστόσο, υπάρχουν ορισμένοι που υπερεκτιμούν τις γνώσεις, ή τις ικανότητές τους σε ένα συγκεκριμένο θέμα, ή δεξιότητα.

Millirobot with a talent for versatility of movement

Tiny robots need not fear obstacle courses in the future: Scientists from the Max Planck Institute for Intelligent Systems in Stuttgart have developed a minuscule, flexible robot that can master a variety of forms of movement. Its magnetic drive allows it to walk, crawl and roll through difficult terrain. Moreover, it can transport small loads and swim on and in liquids. In future, tiny robots moving in this way could transport medication specifically to where it is needed._ Max Planck Gesellschaft.

New Egyptian dinosaur reveals ancient link between Africa and Europe

When it comes to the final days of the dinosaurs, Africa is something of a blank page. Fossils found in Africa from the Late Cretaceous, the time period from 100 to 66 million years ago, are few and far between. That means that the course of dinosaur evolution in Africa has largely remained a mystery. But in the Sahara Desert of Egypt, scientists have discovered a new species of dinosaur that helps fill in those gaps: Mansourasaurus shahinae, a school-bus-length, long-necked plant-eater with bony plates embedded in its skin._ Ohio University

A new Oligo–Miocene marsupial lion from Australia and revision of the family Thylacoleonidae

A team of Australian scientists has discovered a new species of marsupial lion which has been extinct for at least 19 million years. The findings, published in the Journal of Systematic Palaeontology, are based on fossilised remains of the animal’s skull, teeth, and humerus (upper arm bone) found by University of New South Wales (UNSW) scientists in the Riversleigh World Heritage Area of remote north-western Queensland.

Scientists observe supermassive black hole in infant universe

A team of astronomers, including two from MIT, has detected the most distant supermassive black hole ever observed. The black hole sits in the center of an ultrabright quasar, the light of which was emitted just 690 million years after the Big Bang. That light has taken about 13 billion years to reach us — a span of time that is nearly equal to the age of the universe._MIT

When water met iron deep inside the earth, it might have created conditions for life

Reservoirs of oxygen-rich iron between the Earth’s core and mantle could have played a major role in Earth’s history, including the breakup of supercontinents, drastic changes in Earth’s atmospheric makeup, and the creation of life, according to recent work from an international research team published in National Science Review. _Carnegie Science
