Researchers of the Human Brain Project (HBP) found that in Parkinson’s disease the volumes of certain brain regions decrease over time in a specific pattern that is associated with clinical symptoms and largely coincides with the pattern described in Braak’s famous staging theory. The new study published in Cortex provides a detailed description of the structural changes over a long period of time and with an unprecedented spatial detail.
Agriculture, loss of habitat or wastewater effluents – human stressors negatively impact biodiversity in streams and rivers. Very little is known yet about the extent to which their capacity for self-purification and other essential ecosystem services are also impacted. An international research team lead by the Helmholtz Centre for Environmental Research (UFZ) has synthesised the globally available research on this topic in a meta-analysis recently published in Global Change Biology. This study provides new initiatives for improved water management.

China's first planetary exploration mission, the Tianwen-1, was launched by the Chinese space agency on 23 July 2020 and successfully arrived at Mars on 10 February 2021. In a paper published in SCIENCE CHINA Earth Sciences, scientists present observations of the solar wind during Tianwen-1's cruise phase from October 2020 to January 2021. The solar wind plasma measured by the Mars Ion and Neutral Particle Analyzer (MINPA) onboard Tianwen-1's orbiter provides 3-months' solar wind measurements at a distance from 25,765,773 to 3,559,077 kilometers upstream of the Mars, as well as the NASA's MAVEN mission and ESA's Mars Express monitoring the Martian space environment at the same time. This might be the beginning of possible joint multi-satellite exploration at Mars and international cooperation with efforts to reveal the relationship between solar activity and Martian climate evolution history.

At the Science7 Dialogue Forum in Berlin/Germany on Tuesday, 31 May, the science academies of the G7 states will publish science-based statements on topics on this year's agenda of the G7 summit at Schloss Elmau/Germany. Key topics of the statements prepared under the leadership of the Leopoldina are the effects of climate change on polar regions and ocean, measures for decarbonisation, the development of antiviral drugs for pandemic preparedness and the need for a One Health approach to address zoonoses and antimicrobial resistance. Representatives of the national science academies will hand over the statements to the German government during the Science7 Dialogue Forum. Media representatives are invited to attend the event and the associated science conference. Prior registration is required.
Human beings, like most organisms, are constantly exposed to alternating colder or warmer temperatures. These environmental variations cause striking metabolic effects and require constant adaptations. While some of these adaptations confer certain beneficial effects on health, the impact of cold and warmth on the various organs in a whole-body context was not known. To understand the overall biological mechanism at stake, a team from the University of Geneva (UNIGE) analysed changes in gene expression simultaneously in various organs in mice. They discovered that all organs strongly react to temperature changes, each showing its own specific modulation. To stimulate research and potential therapeutic applications, the scientists created a web-based application where thousands of gene expression profiles are freely accessible. These results can be read in the journal eLife.
New research modeling smoke from two recent megafires sets the stage for better forecasting of how emissions from these global-scale events will behave and impact temperatures. As huge wildfires become more common under climate change, increased attention has focused on the intensity and duration of their emissions, which rival those of some volcano eruptions.

Seasonal imbalance between the solar energy absorbed and released by the planet Mars could be a cause of the Red Planet’s dust storms, according to new research from the University of Houston. Understanding how the system works on Mars could help scientists predict how climate change could affect Earth.

As fierce wildfires spread through New Mexico, burning hundreds of structures and forcing thousands of residents to evacuate, Sandia National Laboratories found a way for the workforce to help.
