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....

Rogers’ paradox: Why cheap social learning doesn’t raise mean fitness
by Marcel Montrey in Evolutionary Games Group
It’s Friday night, you’re lonely, you’re desperate and you’ve decided to do the obvious—browse Amazon for a good book to read—when, suddenly, you’re told that you’ve won one for free. Companionship at last! But, as you look at the terms and conditions, you realize that you’re only given a few options to choose from. You […]... Read more »

An approach towards ethics: primate sociality
by Alexander Yartsev in Evolutionary Games Group
Moral decision making is one of the major torrents in human behavior. It often overrides other ways of making judgments, it generates conflicting sets of cultural values and is reinforced by them. Such conflicts might even occur in the head of some unfortunate individual, which makes the process really creative. On the other hand ethical […]... Read more »

Cross-cultural variation in men’s preference for sexual dimorphism in women’s faces
by Farid Pazhoohi in Epistemophil
Both attractiveness judgements and mate preferences vary considerably cross-culturally. We investigated whether men’s preference for femininity in women’s faces varies between 28 countries with diverse health conditions by analysing responses of 1972 heterosexual participants. Although men in all countries preferred feminized over masculinized female faces, we found substantial differences between countries in the magnitude of […]... Read more »

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.
