Looking for clues for past life on Mars

by EE Giorgi in CHIMERAS

NASA's Curiosity Mars. Credits: NASA/JPL-Caltech/MSSSOn August 6, 2012, the NASA Curiosity rover landed on Mars at the base of Mount Sharp, a mountain the size of Kilimanjaro (~19,000 feet) in the middle of Gale Crater. Nina Lanza, space scientist at the Los Alamos National Laboratory, remembers the day well. As part of the team that built ChemCam, one of the ten instruments on the rover, she spent three months at the Jet Propulsion Laboratory in California, living on “Mars time” to fol........

On the impact of blogging — or how far does my message mix?

by Mirjam Sophia Glessmer in Adventures in Oceanography and Teaching

What is the impact of this blog? And who am I writing it for? Those are not questions I regularly ask myself. The main reason I started blogging was to organise all the interesting stuff I was collecting for my introduction to oceanography lecture at the University of Bergen in one place, so I would…...

Nonlinear effects in shallow water waves

by Mirjam Sophia Glessmer in Adventures in Oceanography and Teaching

I recently googled for something related to the shape of waves and came across a photo of a wave that caught my eye, and it took me to a journey that lead to the article “nonlinear shallow ocean wave soliton interactions on flat beaches” by Ablowitz and Baldwin (2012). What’s discussed in that article is that while…... Read more »

Friday Fellow: Northern Plaited Radiolarian

by Piter Boll in Earthling Nature

by Piter Kehoma Boll Some weeks ago I introduced a diatom here and mentioned that, despite the fact that they are a very abundant group, little information on species is available. Today our species is a radiolarian and, just as … Continue reading →... Read more »

The Reconstruction of Ships: Sailing the Seas of International Collaboration

by Filipe Castro in United Academics

Working for both public and private institutions, archaeologists constantly construct and deconstruct narratives about our past, but traditionally publish only a fraction of the sites they excavate and thus destroy. Computers and the internet present a vast range of opportunities for archaeologists to share primary data and foster intercultural online collaborations and reinterpretations of archaeological contexts. ...

Climate change, the long view

by gdw in FictionalFieldwork

Now and forever, or at least for a very long time By 2050, sea levels will have risen this much. If we don’t act, average global temperature will rise x degrees by 2100. These are the things we all hear in the discussion concerning climate change and its consequences. But beyond the turn of the […]... Read more »

Of microbes and men: Evolving as one and terraforming earth

by gdw in FictionalFieldwork

Me and my microbes In the past decade or so, the microbiota, the community of microbes that makes its home in the guts of humans and other animals, has become quite a popular research topic. Quite rightly so, since our little guests seem to affect aspects of our lives that we wouldn’t necessarily consider to […]... Read more »

The unintended consequences of almond milk on California

by Dr. Jekyll in Lunatic Laboratories

A new study using aerial imagery across the state of California has found that converting land to grow almonds between 2007 and 2014 has led to a 27% annual increase in irrigation demands—despite the state's historic drought. The expansion of almonds has also consumed 16,000 acres of wetlands and will likely put additional pressure on already stressed honeybee populations.

Largest-ever study reveals environmental impact of genetically modified crops

by Dr. Jekyll in Lunatic Laboratories

According to new research, widespread adoption of genetically modified crops has decreased the use of insecticides, but increased the use of weed-killing herbicides as weeds become more resistant. This is the largest study of genetically modified crops and pesticide use to date. The team of economists studied annual data from more than 5,000 soybean and 5,000 maize farmers in the U.S. from 1998 to 2011, far exceeding previous studies that have been limited to one or two years of data.

Food waste could store solar and wind energy, or there's the obvious...

by Dr. Jekyll in Lunatic Laboratories

Saving up excess solar and wind energy for times when the sun is down or the air is still requires a storage device. Batteries get the most attention as a promising solution although pumped hydroelectric storage is currently used most often. Now researchers are advancing another potential approach using sugar alcohols—an abundant waste product of the food industry—mixed with carbon nanotubes.

Drugs in the water? Don't blame the students

by Dr. Jekyll in Lunatic Laboratories

With nearly sixty percent of American adults now taking prescription medications--from antidepressants to cholesterol treatments--there is growing concern about how many drugs are flowing through wastewater treatment facilities and into rivers and lakes. Research confirms that pharmaceutical pollution can cause damage to fish and other ecological problems--and may pose risks to human health too.
