Mycotoxin protects against nematodes







Researchers at ETH Zurich have isolated a protein from a fungus of the spruce which combats nematodes. The scientists hope that toxins of this kind will become the basis for the vaccination of livestock or domestic animals against zooparasitic nematodes.
Ερευνητές στο ETH Zurich απομόνωσαν πρωτεΐνη η οποία πυροδοτεί τον αμυντικό μηχανισμό των μυκήτων ( όπως είναι τα μανιτάρια ) και φαίνεται να καταπολεμά νηματώδεις σκώληκες. Παράγεται κυρίως στον πίλο (καπέλο) των μανιταριών. Οι επιστήμονες ελπίζουν ότι οι τοξίνες αυτού του είδους θα αποτελέσουν τη βάση για τον εμβολιασμό των ζώων ή κατοικίδιων ζώων κατά των παρασιτικών νηματωδών.

Birth of a star in double-quick time



Scientists observe the nurseries of massive stars in our galaxy


Astronomers have undertaken a new survey of the plane of our Milky Way and discovered a large quantity of cold, dense clumps of gas and dust, apparently the cradles of massive stars. A team headed by Timea Csengeri from the Max Planck Institute for Radio Astronomy in Bonn has now used the map, which was obtained by the APEX telescope at a wavelength of 0.87 millimetres, to estimate the time scale for the formation of stars.

The result: the process seems to proceed very rapidly, with massive stars taking only 75,000 years to form on average, a significantly shorter time than less massive stars.

Radiation from Early Universe Found Key to Answer Major Questions in Physics



Astrophysicists at UC San Diego have measured the minute gravitational distortions in polarized radiation from the early universe and discovered that these ancient microwaves can provide an important cosmological test of Einstein’s theory of general relativity.

These measurements have the potential to narrow down the estimates for the mass of ghostly subatomic particles known as neutrinos.

Ice-loss moves the Earth 250 miles beneath our feet



At the surface, Antarctica is a motionless and frozen landscape.  Yet hundreds of miles down the Earth is moving at a rapid rate, new research has shown.

The study, led by Newcastle University, UK, and published this week in Earth and Planetary Science Letters, explains for the first time why the upward motion of the Earth’s crust in the Northern Antarctic Peninsula is currently taking place so quickly.

Syracuse University Physicists Confirm Existence of New Type of Meson

Physicists in the College of Arts and Sciences have made several important discoveries regarding the basic structure of mesons—subatomic particles long thought to be composed of one quark and one antiquark and bound together by a strong interaction.
