A major climate event millions of years ago that caused substantial change to the ocean's ecological systems may hold clues as to how the Earth will respond to future climate change, a Florida State University researcher said.

In a new study published in Earth and Planetary Science Letters, Assistant Professor of Geology Jeremy Owens explains that parts of the ocean became inhospitable for some organisms as the Earth's climate warmed 94 million years ago. As the Earth warmed, several natural elements -- what we think of as vitamins -- depleted, causing some organisms to die off or greatly decrease in numbers.

Hydroponics and new, high-tech urban agricultural techniques are now growing fresh food in the middle of Manhattan and other large metropolitan centers globally. People are catching onto the taste and business opportunities of urban agriculture: find it growing in Middle Eastern cities such as Cairo, Egypt too!

Urban farming in midwestern American cities like Chicago has had its limitations due to adverse winter weather conditions at least 9 months a year. New indoor farming techniques use vertical farming, special indoor LED lighting and hydroponic systems that pump soybean and kelp-infused water through a temperature and humidity-controlled system, nearly 24 hours a day, 365 days a year.

PHYSICS HAS ITS own Rosetta Stones. They’re ciphers, used to translate seemingly disparate regimes of the universe. They tie pure math to any branch of physics your heart might desire.

It’s in electricity. It’s in magnetism. It’s in fluid mechanics. It’s in gravity. It’s in heat. It’s in soap films. It’s called Laplace’s equation. It’s everywhere.

Laplace’s equation is named for Pierre-Simon Laplace, a French mathematician prolific enough to get a Wikipedia page with several eponymous entries. In 1799, he proved that the the solar system was stable over astronomical timescales—contrary to what Newton had thought a century earlier. In the course of proving Newton wrong, Laplace investigated the equation that bears his name.

It has just five symbols. There’s an upside-down triangle called a nabla that’s being squared, the squiggly Greek letter phi (other people use psi or V or even an A with an arrow above it), an equals sign, and a zero. And with just those five symbols, Laplace read the universe.

Los investigadores del Centro RIKEN de Ciencia sobre Recursos Sustentables en Japón, han demostrado que la biomasa torrefactada (biomasa que ha sido calentada en ausencia de oxígeno, NT) puede mejorar la calidad de los suelos pobres que se encuentran en regiones áridas. Publicado en informes científicos, el estudio mostró que la adición de biomasa torrefactada al suelo pobre de Botsuana aumenta la retención de agua en el suelo, así como el crecimiento de las plantas.

Elementary particles are the fundamental buildings blocks of matter, and their properties are described by the Standard Model of particle physics. The discovery of the Higgs boson at the CERN in 2012 constitutes a further step towards the confirmation of the Standard Model. However, many aspects of this theory are still not understood because their complexity makes it hard to investigate them with classical computers. Quantum computers may provide a way to overcome this obstacle as they can simulate certain aspects of elementary particle physics in a well-controlled quantum system. Physicists from the University of Innsbruck and the Institute for Quantum Optics and Quantum Information (IQOQI) at the Austrian Academy of Sciences have now done exactly that: In an international first, Rainer Blatt's and Peter Zoller's research teams have simulated lattice gauge theories in a quantum computer. They describe their work in the journal Nature.
