Here, I am collecting samples with teammates; we were volunteers with a marine biology research project. We were called the ‘goats;’ we spent our time on sharp, slippery rocks to get to the tide-pools. The cool kids did the diving and underwater tasks.

My blog: à propos
Salvador Dali and Walt Disney tell a story: Destino. It’s a gem of an animated film. A beautiful, surreal love story. It was produced in the 1940s but only finished and presented to the world over half a century later.

Structural biology: doors open at the European XFEL
Scientists can get ready to blam at 27,000 pulses per second so they can ‘see’ proteins, viruses, single particles. The European XFEL is open with a beam brighter than those at all other existing X-ray sources.

The EuXFEL will produce data mountains, so here is some of the software researchers can use for analysis. And even though there are large facilities, one day, a table-top XFEL might help with experiments, too.

Neurobiology: learning from marmosets
These New World monkeys are social chatterboxes. They communicate with all sorts of postures and calls, they rear their young cooperatively, they can learn to do cognitive tests such as selecting images on a screen. The images change and the marmoset learns which new ones are correct. Some scientists head into the wild to study these animals. Here is a blog post with more about that work.

These animals can help to study the brain and social behavior and can help researchers study autism, depression and many mental health conditions and brain disorders. It’s also “ethically incombent on us to take really good care of these animals and to never think of them as a routine preparation,” says Steven Hyman of the Broad Institute of Harvard and MIT, who is a former director of the National Institute of Mental Health.

The big challenges of big data
Biologists are joining the big-data club, and not just so they can act like they have things to talk about with physicists who juggle big data all the time. Biologists are pushing data mountains around; swapping and comparing big genomics data on various clouds, deciding whether to bring the data to the tools or the tools to the data. Some wet-worlders become in silico worlders.

Microbiology: the road to strain-level identification
Who is there? Who is in a soil or water sample?

With metagenomics, researchers can use DNA sequencing reads to find out, for example, how the gut microbiome differs between individuals with and without Crohn’s disease; or how bacterial diversity differs in samples of soil removed at different times from the same location or in ocean water samples taken at varying time points or depths.

Researchers want to identify not only microbial species but microbial strains. And that goal takes special tools best explained with a tale about a medieval monk tasked to copy all of Europe’s libraries.

Cell communication: Stop the microbial chatter
Bacteria are chatterboxes. They communicate with one another, in large groups, and even across species. This exchange helps them survive and also helps them become more resistant to antibiotics. But by undermining all this chatter, scientists hope to treat infections in new ways. To do so, they are developing new ways to eavesdrop on microbial communication.

The return of culture
Did culture, the act of coaxing growing microorganisms on plates, ever leave microbiology? It never left but it’s true that sequencing and computational techniques sort of took over, in a compelling productive way. But researchers want culture back

Technology: In DSpace, Ideas Are Forever
The libraries at the Massachusetts Institute of Technology are earnestly bookish (2.6 million volumes and 17,000 journals) but increasingly digital (275 databases and 3,800 electronic journals). And just as e-mail dealt a blow to snail mail, digital archives are retooling scholarly exchange. A number of universities, from the California Institute of Technology to M.I.T., are creating ”institutional repositories” designed to harness their own intellectual output. M.I.T.’s archive, perhaps the most ambitious, is called DSpace (www.dspace.org).

Scholarly Storage: Traditionally, journals make research public after peer review, which can take months, sometimes years. Archives like DSpace, however, collect unpublished work — documents of any length, lecture notes, photos, videos, computer simulations, blueprints, software — in all disciplines and make most of it available to anyone as soon as it’s received.

Steam power takes to the road again
To the engineers and steam buffs gathered in the auditorium, most of the images in Roger Waller’s video were familiar enough – the gleaming bulk of a black locomotive standing in Waller’s workshop, a small loco climbing a precipitous mountain railway, an elegant paddle steamer crossing the blue waters of a Swiss lake. What caused a ripple of surprise, though, was a short sequence near the end. It showed a small green car with a round silver tank zipping along a Swiss road, its twin exhausts puffing out clouds of white vapour.

Waller is a modern steam pioneer. Along with a team at his engineering company DLM in Schaffhausen, northern Switzerland, he has spent the last decade redesigning and modernising steam locomotives to make them far cleaner, and more profitable, than “old steam”.


Plants
Nature Methods, July 2016
Plants: a tool box of cell-based assays
Plant biologists have a range of cell-based assays to choose from.

The Trembling Giant is a forest of 50,000 aspens. It’s around 80,000 years old. The plants are all identical. How might they have survived climate change and predation, wonders David Galbraith of the University of Arizona. Perhaps the plants and their cells are not so identical after all. That’s not so easy to study, but one way to do so is with protoplasts, plant cells without walls.

At MGH, plant biologist Jen Sheen has been working with protoplasts since 1987. cellswithoutwallsHer advisers and prominent plant biologists back then feared the assay was too “artificial,” she recalls. Some scientists still have strong reservations. After all these are assays with cells that are cells ‘undressed’.

Some researchers wonder if the cells are too stressed and their physiology is too altered to allow study. But protoplasts have many fans, who assess stress levels and use them to explore many types of molecular aspects with these cells. They use protoplasts, for example, to explore many questions., well aware that this is a transient assay. The cells don’t stay naked forever, the cell walls grow back.

The Metropolis of Science explores the history of science and technology in New York City. Here’s my entry.
Yellow Fever Fence
Yellow fever outbreaks first hit New York in 1668 and hit the city again and again. “Coffins, coffins of all sizes!” is what boys shouted through the city streets, touting the pine coffins for the many dead. The four-dollar price tag was too steep for many people. Nightly, a dead cart carried corpses to the pits of Potter’s Field, now the site of Washington Square Park. In 1822, New York City officials closed off a portion of lower Manhattan in an effort to combat repeated outbreaks.

Metropolis of Science is a web-based web based mapping project led by Marguerite Holloway at Columbia University.

The DNA of a nation
The 100,000 genomes in the 100,000 Genomes Project are not quite sequenced and analyzed yet. Here is a glimpse behind the scenes on some of what it takes to organize the project. Data need to be secured, reliable software pipelines must be put in place and tested. And plenty of experts are needed on hand for manual analysis, genomic deep-diving and general quality control.

The project’s idea is to help people, at first people with rare diseases and cancer. But at one not so distant point, whole genome sequencing might be a common element in the medical records of all of the UK’s National Health Service patients. And along the way it might all spark a genomics industry in the UK.

A most exceptional response
Some cancer patients fare exceptionally well with their treatment, better than others with the same diagnosis. Researchers are keen to understand what makes these so-called exceptional responders so exceptional. It seems un-scientific to think of an individual when research , for example clinical trials, focuses on large numbers of patients, or as large a group as they can find. But this n of 1 approach is promising.

Loren Looger
He likes his shirts and biosensors bright. Loren Looger, who leads a research group at Howard Hughes Medical Institute’s Janelia Farm Research Campus, lights up message transfer in the brain. And he wants to go even further than tracking excitatory messages.

“Proteins are pretty [expletive] awesome,” says Looger. “They are everywhere, doing everything,” handling many biological jobs from lending Spinosaurus its size and a cheetah its speed to helping organisms survive and adapt. To harness that versatility, he engineers proteins with methods that are “equal parts conceptual, modeling based and recreating Darwinian selection in the lab.”


Nature Methods, June 2016
Richard D. Cummings
Rick Cummings, a researcher at Harvard Medical School, cares about sugars. There’s a whole glyco-world out there, he says. Glycans play a role in metabolism and in many disorders. For the longest time, the field was considered marginal. Meetings were more like tea-parties of a few friends, says Cummings. But then things changed. Which makes him all the happier when he comes to the lab and when he sits down at the piano.

…Growing up in rural Alabama, Cummings was drawn to the piano at the ripe age of five. “If you wanted any other noise other than bees humming and birds singing, you had to make it yourself,” he says.
