A trip into bipolar brains

Science Focus

original post »

While people with Type I and the less-severe Type II bipolar disorder share some of the same symptoms, there are significant differences in the physical structure of their brains. Type I sufferers have somewhat smaller brain volume, researchers report in the Journal of Affective Disorders, while those with Type II appear to have less robust white matter.

As brain imaging technologies have advanced and matured over the past few decades, there's been considerable interest in understanding whether and how there are differences between the brains of people with mental illness and those without. In particular, neuroscientists studying depression have been interested in structural variation, such as differences in total brain volume. Still, the various forms of bipolar disorder have received somewhat less attention than others, such as major depression, schizophrenia, or autism.

That led Jerome Maller and colleagues at Monash University in Melbourne, Australia, to look into whether there were structural differences among the brains of people with different sorts of bipolar disorder. Using standard MRI scans — much the same as you would get if you'd had a concussion or bleeding in the brain — on 16 Type I and 15 Type II bipolar patients along with 31 healthy control subjects, the team examined whether there were differences in gray matter, white matter, and cerebrospinal fluid. The team also used a relatively new technique called diffusion tensor imaging (DTI) to measure the integrity of the brains' white matter, the long nerves called axons that connect different brain regions to each other.

Overall, there was less total brain volume — gray and white matter volume added together — and more cerebrospinal fluid volume in bipolar patients than in healthy controls, consistent with other recent studies suggesting a connection between brain volume and depression. After controlling for total brain volume, however, Type II patients' brains were essentially the same as controls' brains, while Type I patients had relatively higher volume in the caudate nucleus and other areas associated with reward processing and decision making. DTI studies, meanwhile, revealed that while patients with Type I and II bipolar disorder had reduced white matter integrity relative to controls, the effect was stronger among those with Type II, particularly in the frontal and prefrontal cortex, suggesting that Type II bipolar disorder is in some way a cognitive dysfunction.

Though the results are intriguing, the authors point out that their study is just the start. The team didn't have access to data on how long patients had been diagnosed with bipolar disorder, let alone how long they'd actually had the disease, which often goes undiagnosed for years or even decades. In addition to addressing those issues in future studies, the researchers also hope to improve sample sizes and gather additional data about factors such as medications, family history, and genetics.

Hack the planet? Comprehensive report suggests thinking carefully first

Science Focus

original post »

Although a growing number of countries are taking steps to reduce their carbon emissions, we're still nowhere close to where we need to be if we want to limit future temperature changes to 2 degrees Celsius. If the coming temperature changes become too disruptive, our future selves may wish that our present selves hadn't released so much carbon.

But they will have options other than looking back with regret. It's possible with existing technologies to pull carbon from the air or to limit the sunlight reaching Earth. These forms of geoengineering are the subject of a new report by the National Academies of Science, funded by everyone from the NOAA and NASA to the US intelligence community. The report concludes that carbon removal from the atmosphere is technically viable, but it's currently too expensive to see widespread use. Altering the amount of sunlight reaching the Earth, however, appears fraught with risks, both practical and political.

The report's authors make one thing clear from the very start: it would be much, much easier to simply limit our carbon emissions now. "There is no substitute for dramatic reductions in the emissions of CO2 and other greenhouse gases," they write, "to mitigate the negative consequences of climate change, and concurrently to reduce ocean acidification." The report's first recommendation is that we focus on mitigation and adaption efforts, as "these approaches do not present poorly defined and poorly quantified risks and are at a greater state of technological readiness."

Carina Nebula in Argo Navis constellation Round Stickers

Here's a great sheet of stickers featuring a beautiful image from deep space


tagged with: stars, galaxies, astronomy, envelope sealers, carina nebula, argos navis constellation, carina the keel, star formation, carnebngcttst, outer space photography, gas clouds, ngc 3372

Galaxies, Stars and Nebulae series Hubble's view of the Carina Nebula shows star birth in a new level of detail. The fantasy-like landscape of the nebula is sculpted by the action of outflowing winds and scorching ultraviolet radiation from the monster stars that inhabit this inferno. In the process, these stars are shredding the surrounding material that is the last vestige of the giant cloud from which the stars were born. The immense nebula is an estimated 7,500 light-years away in the southern constellation Carina the Keel (of the old southern constellation Argo Navis, the ship of Jason and the Argonauts, from Greek mythology).
The original image is a mosaic of the Carina Nebula assembled from 48 frames taken with Hubble Space Telescope's Advanced Camera for Surveys. The Hubble images were taken in the light of ionized hydrogen. Colour information was added with data taken at the Cerro Tololo Inter-American Observatory in Chile. Red corresponds to sulfur, green to hydrogen, and blue to oxygen emission.

CERN accelerators boost argon into action




Argon ions collide with scandium in the NA61/SHINE experiment at CERN (Image: NA61)




CERN’s accelerators supply a raft of experiments with all sorts of different particles. Now the accelerator complex is performing a new trick: supplying argon ions to an experimental programme for the first time. The argon ions are produced at a special source and made to circulate around four accelerators before being sent to a target.


Preparations for this beam of argon ions have been in progress at the CERN accelerator chain for two years. Controlling these particles, which have a much greater mass than protons and are sent at six different energies, is no mean feat. The machine operators had to adapt the acceleration system of the Super Proton Synchrotron (SPS), a 7-kilometer-circumference accelerator that represents the last loop on the ions’ journey before they are ejected.


The SPS is the last accelerator in the chain before the 27-kilometer-circumference Large Hadron Collider (LHC). To allow eight weeks of physics with argon ions while also sending protons to the LHC experiments, the accelerators will alternate between these two types of particles. In each cycle of 21.6 seconds, the SPS will deliver two beams of protons and one beam of argon ions.


The argon ions are destined for the NA61/Shine experiment, which is studying the phenomenon of quark-gluon plasma, a state which is thought to have existed at the very beginning of the universe and in which quarks moved around freely, unconfined by the strong force in protons and neutrons. More specifically, the experiment is studying the transitions between the phase in which quarks are confined and the phase in which they are free. On Thursday last, the NA61/SHINE team recorded first collisions with argon: the argon ions, travelling with a momentum of 150 GeV/c per nucleon, collided with scandium nuclei.


CERN’s accelerators accelerate protons most of the time, but occasionally juggle with other particles. Aside from lead ions and now argon ions, the complex has also accelerated electrons, positrons, antiprotons, deuterons and a particles, as well as oxygen, sulphur and indium ions. These particles are either collided with each other or sent to targets to create beams of secondary particles, such as neutrinos. The accelerator complex supplies around twenty experiments studying a wide range of physics phenomena, such as antimatter, exotic nuclei, neutrinos, cosmic rays, the strong interaction and the Higgs boson. Some are looking for signs of physics beyond the current theories or for as yet unknown particles that might help to account for dark matter. They include the four main LHC experiments ALICE, ATLAS, CMS and LHCb, which are the best known and which will be back in action as of the spring. In addition, several dozen experiments are carried out each year at the ISOLDE and n_TOF nuclear physics facilities.
