"...Instead of printing ...., this machine has the ability to do most of the typical farm jobs that would normally require hard labor and/or individual machines. It can be equipped with different tools, in a similar way as a CNC machine is. Some of those tools include seed injectors, plows, burners, robotic arms (for harvesting), cutters, shredders, tillers, discers, watering nozzles, sensors and more. The hardware used is completely open source and totally scalable for use on any sized farm/garden plots...."
"A balanced assessment of ecosystem services provided by agriculture requires a systems-level socioecological understanding of related management practices at local to landscape scales. The results from 25 years of observation and experimentation at the Kellogg Biological Station long-term ecological research site reveal services that could be provided by intensive row-crop ecosystems. In addition to high yields, farms could be readily managed to contribute clean water, biocontrol and other biodiversity benefits, climate stabilization, and long-term soil fertility, thereby helping meet society's need for agriculture that is economically and environmentally sustainable.

Ecologists may be underestimating the impact of logging in old-growth tropical forests by failing to account for subtleties in how different animal groups respond to the intensity of timber extraction, argues a paper published today in the journal Current Biology. The study, led by Zuzana Burivalova of ETH Zurich, is based on a meta-analysis of 48 studies that evaluated the impact of selective logging on mammals, birds, amphibians, and invertebrates in tropical forests.
Scientists say an outbreak of beet western yellows virus is one of the worst cases ever seen in Australia.
Early estimates suggest up to 10,000 hectares of canola have been affected, in South Australia's lower north, mid north and lower mallee regions. The virus is transported by green peach aphids, which have thrived in the state's recent warm and humid weather. Ag consultant Mick Faulkner says agronomists felt like they'd been "blind-sided" after not being able to work out what had been affecting crops. "It took everyone a fair bit of time to realise that we weren't killing the aphids," Mr Faulkner said. "Green paddocks are now brown. "Those that have been affected, I have grave fears that they won't yield anything at all."
Virus halted for now - The South Australian Research and Development Institute (SARDI) says it's now testing samples to confirm how the virus is spreading and where else it might turn up. Pulse pathologist Jenny Davidson says with cooler weather, the virus-transmitting aphids aren't moving and at the moment the best thing growers can do is "nothing", "We expect that the spread of this virus would've stopped for now, so there's no point people going out and spraying aphids now," she says. "It's also important growers ascertain it actually is the virus causing problems in their canola crops, there may be other things going on as well. "The potential risk is what these aphids will do in spring time. "We're not sure whether or not pulse crops are at risk but we'll have that information back well and truly before the spring time flights." Ms Davidson says the virus isn't uncommon, but what is unusual is the extent of damage and infection being seen. She says it's taken everyone by surprise. "I've never seen this level of damage from any virus in crops," Ms Davidson says. "It's the magnitude of what we're dealing with that is totally un-expected."
The 1000 Fungal Genome (1KFG) project is a large-scale community sequencing project supported by the Joint Genome Institute (JGI). The goal of 1KFG is to facilitate the sequencing of fungal genomes across the Kingdom Fungi with the objective to significantly advance genome-enabled mycology. The sampling guideline is to sequence two species of fungi for every family-level clade of Fungi so that genomic data is representative of phylogenetic diversity of Fungi. In support of this endeavor, 1KFG is pleased to announce the Graduate Student/Postdoc Challenge. From July 2014-June 30 2015 we will accept nominations to sequence up to 100 species of fungi in support of graduate student and postdoctoral research projects. Students and postdocs are encouraged to nominate species and submit DNA and RNA samples for genomic sequencing.

Climatologists have spent decades politely warning that we are cooking our planet, but now one has decided to stop sugar coating it. Professor Jason Box of the Geological Survey of Denmark and Greenland tweeted “If even a small fraction of Arctic sea floor carbon is released to the atmosphere, we're fucked.”
Spectacular transitional fossils, many from northern China, provide overwhelming evidence that dinosaurs evolved into birds and thus didn’t all perish when the deadly meteorite struck at the end of the…
What Luigi Guarino on the "Agricultural Biodiversity Weblog" wrote about it:
From Spain, there’s news of how an old variety — and much effort from a local family — brought back the particular taste of Los Monegros’ bread. Should anyone else be interested, the variety in question, Aragon 03, seems to be available in various genebanks.
In December of 2012, three young men were living in a claustrophobic apartment in San Francisco’s Tenderloin district, working on a technology startup. They had received a hundred and seventy thousand dollars from the incubator Y Combinator, but their project—a plan to make inexpensive cell-phone towers—had failed. Down to their last seventy thousand dollars, they resolved to keep trying out new software ideas until they ran out of money. But how to make the funds last? Rent was a sunk cost. Since they were working frantically, they already had no social life. As they examined their budget, one big problem remained: food.
Sequence-specific nucleases have been applied to engineer targeted modifications in polyploid genomes1, but simultaneous modification of multiple homoeoalleles has not been reported. Here we use transcription activator–like effector nuclease (TALEN)2,3 and clustered, regularly interspaced, short palindromic repeats (CRISPR)-Cas9 (refs. 4,5) technologies in hexaploid bread wheat to introduce targeted mutations in the three homoeoalleles that encode MILDEW- RESISTANCE LOCUS (MLO) proteins6. Genetic redundancy has prevented evaluation of whether mutation of all three MLO alleles in bread wheat might confer resistance to powdery mildew, a trait not found in natural populations7. We show that TALEN-induced mutation of all three TaMLO homoeologs in the same plant confers heritable broad-spectrum resistanceto powdery mildew. We further use CRISPR-Cas9 technologyto generate transgenic wheat plants that carry mutations inthe TaMLO-A1 allele. We also demonstrate the feasibility of engineering targeted DNA insertion in bread wheat through nonhomologous end joining of the double-strand breaks caused by TALENs. Our findings provide a methodological framework to improve polyploid crops.
