Phys.org / The strange history of Czech cactus hunters, and why some see themselves as Robin Hood figures
Four Czech men were arrested at Guarulhos International Airport in São Paulo, Brazil, in February this year on charges of smuggling native species.
Phys.org / New Horizons tracks solar wind slowdown as interstellar atoms add drag
A new Southwest Research Institute (SwRI) study based on data from NASA's New Horizons spacecraft has uncovered insights into why the solar wind gradually slows as it moves toward the edge of the solar system and the boundary ...
Phys.org / Warming can shift freshwater crustaceans to a 'greener' diet
Climate change is not only warming our lakes and rivers, it is also changing what invasive species eat. A new experimental study published in Limnology and Oceanography Letters shows that temperature-driven diet shifts in ...
Phys.org / Ozone depletion began decades before discovery of ozone hole, scientists find
The Antarctic ozone hole was discovered in 1985, when scientists observed a severe depletion in Earth's protective layer of stratospheric ozone. Industrial chemicals known as chlorofluorocarbons (CFCs), then widely used as ...
Medical Xpress / Experimental vaccine for 'neglected disease' carried by hundreds of millions of people shows promising results
For a vaccine to be effective, it must do two things. First, it must trigger an immune response. Second, the vaccine must train the body to remember the response so it can fight that same disease in the future. Now, new research ...
Phys.org / Ultra-faint galaxy discovered near Andromeda may be 12.5 billion years old
A new ultra-faint dwarf galaxy has been discovered in the vicinity of Andromeda (M31), the Milky Way's large neighboring galaxy. The new study, published in Astronomy & Astrophysics suggests that the galaxy, named And XXXVI, ...
Phys.org / Disorder creates direction-dependent optics in compound semiconductors
An international research team has demonstrated that the intrinsic disorder of the compound semiconductor CuInSnS₄ can be exploited to influence its optical properties. While the atomic vibrations also sense the local disorder, ...
Medical Xpress / When back pain won't quit: A large clinical trial points to the power of self-management
Almost everyone will deal with back pain at some point in their lives. Most recover quickly—but for about 20% of people, acute pain becomes a chronic condition that interferes with daily life and keeps them out of the workforce.
Phys.org / Why Europe's rising plant diversity may signal habitat disruption, not ecological recovery
The number of plant species in many ecosystems in Europe has grown rather than shrunk over the last 100 years. However, this is not necessarily cause for celebration, as this local increase is primarily due to generalists ...
Medical Xpress / Treatment for alcohol use disorder can reverse harmful brain effects
When we drink alcohol, our liver breaks it down into acetate, which the body can then burn as fuel. A new Neuropsychopharmacology study has discovered that chronic alcohol use can alter how the brain metabolizes acetate—and ...
Phys.org / Data suggest greater glacial flood risk faced by Bhutan
Researchers at Newcastle University have carried out the first comprehensive modeling of glacial lake outburst flood (GLOF) risk in Bhutan and identified previously unrecognized high-risk lakes.
Medical Xpress / Neural pathways reveal a push-pull system for coordinating goal-directed behavior in mice
Most of the tasks that humans complete daily entail carefully coordinating movements and tracking progress made toward a desired goal. Past studies have highlighted the role of the basal ganglia (BG), a set of interconnected ...
