A new paper presents a mathematical model for the motion of bacteria that includes cell division and death, the basic ingredients of the cell cycle.
When our vertical perception gets distorted: Body pitch and translational body motion
Taking Hong Kong's famous Peak Tram up to Victoria Peak offers stunning views of its central business district, Victoria Harbor, and the surrounding islands. But a team of international scientists has recently discovered that the trams winding journey provides a previously unrecognized situation where our vertical perception gets distorted.
Alveolar macrophages help CD8+ T cells go (anti-)viral
Researchers have found that antigen-specific killer T cells (CD8+ T cells) rapidly expand in the lungs when primed by antigen-presenting lung-resident alveolar macrophages (AMs). This interaction helps protect against viral infection and could form the basis for developing 'cell transplant'-type vaccines in the future.
Skiing over Christmas holidays no longer guaranteed — even with snow guns
For many people, holidays in the snow are as much a part of the end of the year as Christmas trees and fireworks. As global warming progresses, however, white slopes are becoming increasingly rare. Researchers have calculated how well one of Switzerland's largest ski resorts will remain snow reliable with...
Ethereal color variant of mysterious plant is actually a new species
It was thought that there was only one species of the ghost-like Monotropastrum humile plant found in woodlands across East and Southeast Asia. In a major new discovery, botanists reveal that a rosy pink colored variant is actually a distinct new species, shaking up our understanding of this unusual-looking genus...
New bacterial therapy approach to treat lung cancer
Researchers report that they have developed a new experimental pipeline to combine bacterial therapy with current cancer drugs. Their study, which explores resistance to bacterial therapy at the molecular level, has achieved better treatment efficacy without additional toxicity in laboratory models.
Archaeologists uncover oldest known projectile points in the Americas
Archaeologists have uncovered projectile points in Idaho that are thousands of years older than any previously found in the Americas, helping to fill in the history of how early humans crafted and used stone weapons.
Plants between light and darkness
How plants optimize photosynthesis under changing light conditions.
Current Antarctic conservation efforts are insufficient to avoid biodiversity declines, study shows
Existing conservation efforts are insufficient to protect Antarctic ecosystems, and population declines are likely for 65% of the continent's plants and wildlife by the year 2100, according to a new study.
Cystic fibrosis drug could help treat pneumonia
Pathogens such as SARS-CoV-2 and pneumococcus can cause severe pneumonia. If the airways then fill with fluid, the patient risks developing acute respiratory distress syndrome. Researchers have now discovered the molecular mechanisms that trigger fluid accumulation in the lungs. This also led them to discover a potential new therapy: A...
