Eileen Higgins won a historic victory in December. She became the first woman ever elected mayor of Miami, as well as its first Democratic mayor since 1997.
The Milan Urban Food Policy Pact recently renewed global commitments to sustainable and equitable urban food systems. The pact has been signed by 330 cities around the world that have pledged to improve food production and distribution and to reduce waste.
A mysterious bar-shaped cloud of iron has been discovered inside the iconic Ring Nebula by a European team led by astronomers at University College London (UCL) and Cardiff University.
Opinion polarization is often considered as the primary driver of social friction, leading to exhaustive efforts to force a consensus. However, new research suggests a more pragmatic goal: reducing the friction of disagreement without necessarily eliminating the diversity of opinion.
Growing up in Greece, wildfires were a constant presence each summer. In 2007, I remember watching TV footage of fires ravaging the Peloponnese peninsula and island of Evia, destroying forests and homes, taking lives. The sight of helicopters and firefighting aircraft crossing the smoky skies was both terrifying and awe-inspiring.
People shouldn't be afraid to say what they think, and new research from the University of Virginia bears that out.
As Earth warms due to climate change, oceans are heating up, becoming more acidic, and losing oxygen. These changes threaten marine life, food webs, and global fisheries. Scientists agree that cutting greenhouse gas emissions is essential, but current efforts are not enough to keep global warming below the 1.5–2 degrees Celsius targets set by the Paris Agreement. Because of this, researchers are exploring climate intervention strategies as possible additions to emissions cuts.
A Purple Star Sapphire weighing 3,563 carats which is claimed to be the world's biggest of its kind was unveiled on Saturday in the Sri Lankan capital by the owners, who are ready to sell the precious stone which is estimated to be worth at least $300 million.
Indigenous communities have lived with changes to the climate for centuries. Their adaptations over those many years are based on their close observation of weather, water, soils and seasonal change, and they have been refined through generations of learning.
Taking images of tiny structures within cells is tricky business. One technique, cryogenic electron tomography (cryoET), shoots electrons through a frozen sample. The images formed by the electrons that emerge allow researchers to reconstruct the internal architecture of a cell in 3D with near-atomic resolution.
