MINNEAPOLIS - While movement problems are the main symptoms of Parkinson's disease, people with the disease often have non-motor symptoms such as constipation, daytime sleepiness and depression 10 or more years before the movement problems start. A new study suggests that eating a healthy diet in middle age may be linked to having fewer of these preceding symptoms. The study is published in the August 19, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology.
Like biological fat reserves store energy in animals, a new rechargeable zinc battery integrates into the structure of a robot to provide much more energy, a team led by the University of Michigan has shown.
This approach to increasing capacity will be particularly important as robots shrink to the microscale and below--scales at which current stand-alone batteries are too big and inefficient.
What The Study Did: This observational study examined the association between state participation in Medicaid expansion through the Affordable Care Act and changes in the use of surgical care for common outpatient procedures.
Authors: Saunders Lin, M.D., of New York University in New York, is the corresponding author.

An international team of researchers have discovered a dense, cold gas that's been shot out from the centre of the Milky Way "like bullets".
Exactly how the gas has been ejected is still a mystery, but the research team, including Professor Naomi McClure-Griffiths from The Australian National University (ANU), say their findings could have important implications for the future of our galaxy.
"Galaxies can be really good at shooting themselves in the foot," Professor McClure-Griffiths said.
Rising temperatures due to our greenhouse gas emissions can cause greater damages to our economies than previous research suggested, a new study shows. Scientists from the Potsdam Institute for Climate Impact Research (PIK) and the Mercator Research Institute for Global Commons and Climate Change (MCC) took a closer look at what climate change does to regions at the sub-national level, such as US states, Chinese provinces or French départments, based on a first-of-its-kind dataset by MCC.
New research looking at voters' perception of gender and aspiration suggests that voters do not penalise ambitious women candidates seeking political office, contrary to popular belief.
The study, published in the US journal Political Behavior, challenges the long-held assumption that negative views about ambition are standing in the way of female candidates in politics.
A team of researchers at DESY has reached an important milestone on the road to the particle accelerator of the future. For the first time, a so-called laser plasma accelerator has run for more than a day while continuously producing electron beams. The LUX beamline, jointly developed and operated by DESY and the University of Hamburg, achieved a run time of 30 hours. "This brings us a big step closer to the steady operation of this innovative particle accelerator technology," says DESY's Andreas R. Maier, the leader of the group.
PULLMAN, Wash. - Washington State University researchers have made a key first step in economically converting plant materials to fuels: keeping iron from rusting.
The researchers have determined how to keep iron from rusting in important chemical reactions that are needed to convert plant materials to fuels, meaning that the cheap and readily available element could be used for cost-effective biofuels conversion.
Over the past two decades, a new area at the interface of semiconductor physics, electronics and quantum mechanics has been gaining popularity among theoretical physicists and experimenters. This new field is called spintronics, and one of its main tasks is to learn how to control the spin of charge carriers in well known semiconductor structures. Many theoretical efforts are always required before some idea finds its embodiment in an actual device, and so far theoretical work on spintronics has been outweighing experimental research.
The team is led by Associate Professor Ayrat Kayumov (Department of Genetics, Kazan Federal University). In this research, the scientists not only performed genome sequencing, but also found a completely new type of PII-Like Protein PotN.
The release of massive amounts of proteins called cytokines can lead to some of the most severe symptoms of COVID-19. When large numbers of immune cells release cytokines, this increases inflammation and creates a feedback loop in which more immune cells are activated and this is sometimes called a cytokine storm.
Covid-19 patients with hypoxia respond positively to icatibant treatment, Radboud university medical center researchers wrote in JAMA Network Open. These findings have led to a follow-up study at ten Dutch hospitals into a drug that may be even more effective. The current study has been funded by ZonMw.
High blood pressure is often called a silent killer because it is the biggest risk factor for the most death and disability worldwide including heart disease and stroke, but presents no symptoms as a warning indicator. Many elderly people have high blood pressure that is difficult to treat, and good preventative methods and appropriate markers have not been elucidated.
All current breast cancer drugs were first tested in cell lines. Each cell line began as cancer in a patient. As such, each cell line is a surrogate for that patient's disease. A new database of 40 breast cancer cell lines, developed by Medical University of South Carolina investigators, will help researchers deepen their understanding of these cell lines and speed the development of new gene-targeted therapies.
When it comes to brain cells, one size does not fit all. Neurons come in a wide variety of shapes, sizes, and contain different types of brain chemicals. But how did they get that way? A new study in Nature suggests that the identities of all the neurons in a worm are linked to unique members of a single gene family that control the process of converting DNA instructions into proteins, known as gene expression. The results of this study could provide a foundation for understanding how nervous systems have evolved in many other animals, including humans.
