Late Cretaceous Period was likely ice-free
For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, a University ...
New study proposes solution to long-running debate as to how stable the Earth system is
Researchers at the University of Southampton have proposed an answer to the long-running debate as to how stable the Earth system is.
Mars soil sample delivered for analysis inside rover
(Phys.org)—NASA's Mars rover Curiosity has ingested its first solid sample into an analytical instrument inside the rover, a capability at the core of the two-year mission.
Mars rover Opportunity working at edge of 'Solander'
(Phys.org) —NASA's Mars rover Opportunity is studying the area of contact between a rock layer formed in acidic wet conditions long ago and an even older one that may be from a more neutral wet environment.
Bio-based solar cell: Researchers generate electricity rather than biomass with photosynthetic proteins
Researchers at the Ruhr-Universität Bochum (RUB) have developed a bio-based solar cell. They embedded the two proteins photosystem 1 and 2, which in plants are responsible of photosynthesis, into complex molecules developed ...
Antarctic ice core contains unrivaled detail of past climate
A team of U.S. ice-coring scientists and engineers in Antarctica, funded by the National Science Foundation (NSF), have recovered from the ice sheet a record of past climate and greenhouse gases in the atmosphere ...
Two years and counting on red planet for NASA Mars Curiosity rover
(Phys.org) —NASA's most advanced roving laboratory on Mars celebrates its second anniversary since landing inside the Red Planet's Gale Crater on Aug. 5, 2012, PDT (Aug. 6, 2012, EDT).
Catastrophic climatic events leave corals facing a decade-long fight for recovery
Marine conservationists from Plymouth University, and the Universidad Federal da Bahia in Brazil, have spent more than 17 years analysing the diversity and density of coral colonies off the coast of South ...
What really happened prior to 'Snowball Earth'?
In a study published in the journal Geology, scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science suggest that the large changes in the carbon isotopic composition of car ...
Even healthy cats act sick when their routine is disrupted
A cat regularly vomiting hairballs or refusing to eat probably isn't being finicky or otherwise "cat-like," despite what conventional wisdom might say. There is a good chance that the cat is acting sick because of the stress ...
The long shot of life elsewhere
Recent research suggests that there may be as many as 40 billion habitable planets in our galaxy. A number that large has some scientists speculating that the universe might be teeming with life.
Modified genetic alphabet: Chemical evolution generates bacterial strain with artificial nucleotide in its genome
(PhysOrg.com) -- Evolution is based on heredity, changes to the genetic material (mutation), and the natural selection of those organisms that are best suited to the given environmental conditions. An international ...
Researchers devise a way to measure volatile organic compound exchange in the atmosphere
Environmental risks of pipeline underestimated
A new UNSW-led study modelling the impacts of an approved $47 million pipeline pumping water from the Macquarie River to the city of Orange reveals far greater risks to river health than those estimated by ...
