Announcing the Allen Cell Explorer

With the launch of the Allen Cell Explorer, scientists around the world will gain an unprecedented view into the organizational diversity of human stem cells, ultimately enabling them to better understand what makes human cells healthy and what goes wrong in disease._ Allen Institute

Γνωστοί θρύλοι στα ίχνη πρωτόγονων πληθυσμών

Πώς η διάδοση των θρυλικών αφηγημάτων από γενιά σε γενιά φωτίζει την μεταναστευτική ιστορία των ανθρώπων μέχρι την Παλαιολιθική περίοδο.

New weapon against Diabetes

Researchers have used the simplest approach yet to produce artificial beta cells from human kidney cells. Like their natural model, the artificial cells act as both sugar sensors and insulin producers._ ETH Zurich

«Pulling» bacteria out of blood

Empa researcher Inge Herrmann and her team are developing a solution in collaboration with modelling expert Marco Lattuada from the Adolphe Merkle Institute and doctors from the Harvard Medical School. The idea for the treatment is the magnetic purification of blood. _Empa

Coral polyps

There are 14 wild orange-bellied parrots left – this summer is our last chance to save them

When only 14 of any species are left in the wild, you know they are in trouble.
Such is the crisis faced by the last remaining population of orange-bellied parrots in southwest Tasmania. To make matters even worse, very few of these birds are females.
On our trip to southwest Tasmania on Tuesday, we found four nests. We will be returning to the site soon to count the fertile eggs.
There have been some heartening stories of the reversal of fortunes when endangered species crash to such low levels, but these stand against a bleak backdrop of increasing extinction rates in the 21st century.

Η «Σιδηρά Χείρ» του Αρχιμήδη

Πριν είκοσι τρεις αιώνες, ο Έλληνας μαθηματικός Αρχιμήδης κλήθηκε από τον βασιλέα των Συρακουσών Ιέρωνα Β’ να σχεδιάσει πολεμικές μηχανές που θα μπορούσαν να αποκρούσουν τους εχθρούς της Ελληνικής αποικίας. Μεταξύ των πολυάριθμων μηχανών που σχεδιάστηκαν, ήταν η περιώνυμη Σιδηρά Αρπάγη, ή Σιδηρά Χείρα, μια συσκευή τόσο αποτελεσματική που απετέλεσε το φόβητρο των Ρωμαίων και το κύριο μέσο άμυνας των Συρακουσών κατά την ναυτική πολιορκία από τον Ρωμαϊκό στόλο το 213 π.Χ.

Twin glacier collapse in Tibet

Giant ice avalanches caused by catastrophic glacier failures are rare events. The collapse of two neighbouring glaciers within two months – as just witnessed in Tibet – was never seen before. The timely analysis of satellite images enabled scientists to issue a warning prior to the second collapse._ ETH Zurich

Vigilin, the lock keeper

ETH researchers have discovered a molecule in liver cells that controls the release of fat into the bloodstream. This “lock keeper” is present in large quantities in overweight people and leads indirectly to vascular narrowing._ ETH Zurich

Protein-like structures from the primordial soup

Experiments performed by ETH scientists have shown that it is remarkably easy for protein-like, two-dimensional structures – amyloids – to form from basic building blocks. This discovery supports the researchers’ hypothesis that primal life could have evolved from amyloids such as these. _Fabio Bergamin ETH Zurich
