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

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)
A promising model for understanding neurological and psychiatric diseases could help provide personalized treatments for patients.
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.
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
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.
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.
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 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. _phys.org
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
DNA bricks enable self-assembly of 3D nanostructures from 10,000 unique components, advancing DNA nanotech from Mega to GigaDalton scale

After 20 years of painstaking excavation and preparation, Professor Ron Clarke introduces the most complete Australopithecus fossil ever found to the world._Wits University
EPFL researchers have successfully measured some of the quantum properties of electrons in two-dimensional semiconductors. This work in the field of spintronics could one day lead to chips that are not only smaller but that also generate less heat. _ EPFL
A new publicly available data set offers a wealth of information on the structure of the disk of the Milky Way and its interstellar medium. _NOAO
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
Read a few lines of Chaucer or Shakespeare and you’ll get a sense of how the English language has changed during the past millennium. Linguists catalogue these changes and work to discern why they happened. Meanwhile, evolutionary biologists have been doing something similar with living things, exploring how and why certain genes have changed over generations.
In a new study published in Nature, researchers in these two academic fields have joined forces at the University of Pennsylvania to solve an essential problem of how languages evolve: determining whether language changes occur by random chance or by a selective force. _University of Pennsylvania

Researchers at EPFL have developed a new device and analysis method that let doctors measure the neurochemicals in a patient’s brain. The Microsystems Laboratory 4 (LMIS4)’s system involves collecting microdroplets of cerebral fluid and analyzing them to obtain chemical data that can help doctors diagnose and treat neurodegenerative diseases._EPFL
Physicists have used the by-products of cosmic rays to reveal a large, previously unidentified chamber inside the 4,500-year-old Great Pyramid in Giza, Egypt. The find is the first discovery since the nineteenth century of a major new space inside the pyramid. _Nature
On Aug. 17, the Laser Interferometry Gravitational-Wave Observatory (LIGO) detected the fifth fingerprint of a massive disturbance in spacetime since LIGO began operations in September 2015. Unlike the first four sets of ripples, which reflected collisions between two black holes, the shape of these spacetime distortions suggested a collision between two neutron stars. _Princeton University
Looking at massive galaxy clusters, EPFL astronomers have observed that their brightest galaxies within them “wobble” — an unexpected phenomenon in current models. The discovery, published in MNRAS, adds to the body of evidence of dark matter beyond the Standard Cosmological Model (ΛCDM). _EPFL
ETH researchers have developed a scale for measuring cells. It allows the weight of individual living cells, and any changes in this weight, to be determined quickly and accurately for the first time. The invention has also aroused significant interest both in and outside the field of biology. _ETH Zurich
