Life on Earth began somewhere between 3.7 and 4.5 billion years ago, after meteorites splashed down and leached essential elements into warm little ponds, say scientists at McMaster University and the Max Planck Institute in Germany.
Their calculations suggest that wet and dry cycles bonded basic molecular building blocks in the ponds’ nutrient-rich broth into self-replicating RNA molecules that constituted the first genetic code for life on the planet.
Ancient rocks in northeastern Canada could contain chemical traces of life from more than 3.95 billion years ago, a new study suggests. If confirmed, the finding would be among the earliest known signs of life on Earth._Nature News & Comment
Φωτοκατευθυνόμενες «μοριακές μηχανές» χρησιμοποιήθηκαν για την διάτρηση της εξωτερικής μεμβράνης σε μεμονωμένα κύτταρα, υποσχόμενες είτε την μεταφορά θεραπευτικών ουσιών μέσα σε πάσχοντα κύτταρα, είτε την άμεση καταστροφή των νεκρωμένων._Πυθεύς
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
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

Scientists at TU Wien (Vienna) have now developed a new concept: By combining highly specialised new materials, they have managed to combine high temperature photovoltaics with an electrochemical cell. Ultraviolet light can be directly used to pump oxygen ions through a solid oxide electrolyte. The energy of the UV light is stored chemically. In the future, this method could also be used to split water into hydrogen and oxygen.__TU Wien
Scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley have found a simple new way to produce nanoscale wires that can serve as tiny, tunable lasers.__LBNL
Researchers have discovered the two-step process that activates an essential human enzyme, called Suv39h1, which is responsible for organizing large portions of the DNA found in every living cell.

In addition to providing a potential answer to longstanding questions surrounding lunar fire fountains, the findings also serve as more evidence that some volatile reservoirs in the Moon’s interior share a common origin with reservoirs in the Earth, the researchers say._Carnegie Science
Μπορεί να το αναπνέουμε κάθε λεπτό, αλλά στο διάστημα δεν βρίσκεται σχεδόν καθόλου μοριακό οξυγόνο. Το 1998, η NASA εκτόξευσε δορυφόρο με την προσδοκία ότι θα έβρισκε αρκετή ποσότητα οξυγόνου, κάτι το οποίο δεν συνέβει και οι επιστήμονες θεωρώντας ότι είχε υποστεί βλάβη στα όργανα μέτρησης, τον κατεύθυναν πίσω στην γή.
