Where do rubber trees get their rubber?
Researchers at the RIKEN Center for Sustainable Resource Science (CSRS) in Japan along with collaborators at Universiti Sains Malaysia (USM) have succeeded in decoding the genome sequence for Hevea brasiliensis, the natural rubber tree native to Brazil. Published in Scientific Reports, the study reports a draft genome sequence that covers more than 93% of expressed genes, and…

Energy from sunlight: Further steps towards artificial photosynthesis
Chemists from the Universities of Basel and Zurich in Switzerland have come one step closer to generating energy from sunlight: for the first time, they were able to reproduce one of the crucial phases of natural photosynthesis with artificial molecules. Their results have been published by the journal Angewandte Chemie (international edition).Green plants are able to temporarily…

Warning from the past: Future global warming could be even warmer
Future global warming will not only depend on the amount of emissions from man-made greenhouse gasses, but will also depend on the sensitivity of the climate system and response to feedback mechanisms. By reconstructing past global warming and the carbon cycle on Earth 56 million years ago, researchers from the Niels Bohr Institute among others…

Researchers discover oldest evidence of 'farming' — by insects
Scientists have discovered the oldest fossil evidence of agriculture — not by humans, but by insects.The team, led by Eric Roberts of James Cook University along with researchers from Ohio University, discovered the oldest known examples of "fungus gardens" in 25 million-year-old fossil termite nests in East Africa.The results are published today in the journal PLOS…

Volcanoes get quiet before they erupt!
When dormant volcanoes are about to erupt, they show some predictive characteristics–seismic activity beneath the volcano starts to increase, gas escapes through the vent, or the surrounding ground starts to deform. However, until now, there has not been a way to forecast eruptions of more restless volcanoes because of the constant seismic activity and gas…

Probing giant planets' dark hydrogen
Hydrogen is the most-abundant element in the universe. It's also the simplest–sporting only a single electron in each atom. But that simplicity is deceptive, because there is still so much we have to learn about hydrogen.One of the biggest unknowns is its transformation under the extreme pressures and temperatures found in the interiors of giant…

2 ways to limit the number of heat-related deaths from climate change
By the 2080s, as many as 3,331 people could die every year from exposure to heat during the summer months in New York City. The high estimate by Columbia University scientists is based on a new model–the first to account for variability in future population size, greenhouse gas trajectories, and the extent to which residents…

94-million-year-old climate change event holds clues for future
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…

Laplace's Equation: Mathematical Key to Everything
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…

Particle zoo in a quantum computer
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…
