While Parkinsons disease typically brings to mind symptoms such as tremors and slow movement, researchers have found that nearly half of all Parkinsons patients also suffer from depression. While it might seem natural that someone who has a disease such as Parkinsons might become depressed, its not so simple, says neurologist Irene Richard, M.D., of the University of Rochester Medical Center.
"Many patients assume thats its normal to feel this way. They might say, If you had Parkinsons disease, youd feel this way too. Thats not true. If you treat the depression, theyll still have the other symptoms of the disease, but they feel better. Its one aspect of the disease that may be very treatable," says Richard. "People diagnosed with other serious diseases that may also be disabling, such as rheumatoid arthritis, arent nearly as likely to become depressed."
Richard and co-author William McDonald, M.D., a psychiatrist at Emory University, discussed the links between depression and movement disorders like Parkinsons disease in a review article in the August 24 issue of the journal Neurology. In an article titled, "Can blue genes affect mood and movement?" the two noted that a team from Columbia University has linked a gene known to cause a movement disorder known as dystonia with a type of early-onset depression. Now they and other physicians around the country are exploring possible links between mood and movement in other disorders such as Parkinsons disease.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
