Missing link in the evolution of complex cells discovered
by Perikis Livas in Chilon
In a new study, published in Nature this week, a research team led from Uppsala University in Sweden presents the discovery of a new microbe that represents a missing link in the evolution of complex life. The study provides a new understanding of how, billions of years ago, the complex cell types that comprise plants, fungi, but also animals and humans, evolved from simple microbes.

Robot Discovers Two New Neighbors
by Perikis Livas in Chilon
Maunakea, Hawaii – A team of astronomers using ground-based telescopes in Hawaii, California, and Arizona recently discovered a planetary system orbiting a nearby star that is only 54 light-years away. All three planets orbit their star at a distance closer than Mercury orbits the sun, completing their orbits in just 5, 15, and 24 days. The paper is being published in the Astrophysical Journal....

Major Advance in Artificial Photosynthesis
by Perikis Livas in Chilon
A potentially game-changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered by solar energy, convert that carbon dioxide into valuable chemical products, including biodegradable plastics, pharmaceutical drugs and even liquid fuels....

Birth of a star in double-quick time
by Perikis Livas in Chilon
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 s........ Read more »

Ice-loss moves the Earth 250 miles beneath our feet
by Perikis Livas in Chilon
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.

At the frontiers of magnetism
by Perikis Livas in Chilon
The smallest possible magnets are the size of a single atom. Now scientists have reached the limits of optimisation of the tiny particles: they have created single atom magnets that are as strong and stable as is physically possible for the class of atoms used.

Entire Star Cluster Thrown Out of its Galaxy
by Perikis Livas in Chilon
The galaxy known as M87 has a fastball that would be the envy of any baseball pitcher. It has thrown an entire star cluster toward us at more than two million miles per hour. The newly discovered cluster, which astronomers named HVGC-1, is now on a fast journey to nowhere. Its fate: to drift through the void between the galaxies for all time.

Search for life on exoplanets more difficult than thought
by Perikis Livas in Chilon
A new study from the University of Toronto Scarborough suggests the search for life on planets outside our solar system may be more difficult than previously thought.
The study, authored by a team of international researchers led by UTSC Assistant Professor Hanno Rein from the Department of Physical and Environmental Science, finds the method used to detect biosignatures on such planets, known as exoplanets, can produce a false positive result.
