### A Year of Scientific Breakthroughs and Environmental Urgency

As half the globe participated in elections, the year 2024 also highlighted significant scientific advancements and pressing environmental concerns. Notably, the cosmos captured widespread attention with spectacular celestial events.

In April, millions marveled at the “Great North American Eclipse,” a total solar eclipse that offered an unprecedented experience for observers, casting its shadow across the continent for the longest duration in over a decade. People engaged in citizen science projects, contributing to valuable data collection aimed at enhancing solar activity models. The year also witnessed vibrant auroras caused by heightened solar activity, with solar physicists excitedly noting an unexpected surge in solar flares.

In another remarkable development, scientists unveiled the first complete brain map of the fruit fly, Drosophila melanogaster, illuminating the intricate connections between its 140,000 neurons. This milestone in connectomics builds momentum towards mapping the extensively complex human brain, a task supported by evolving AI technologies.

On the climate front, 2024 recorded unprecedented heat levels, with temperatures exceeding 1.5 degrees Celsius above the pre-industrial average. The alarming rise in global temperatures led to widespread coral bleaching and intense weather patterns, while greenhouse gas emissions defied expectations by increasing again. Nonetheless, policy shifts, including substantial funding from the Inflation Reduction Act in the U.S., are sparking hope for future decarbonization efforts.

The journey toward understanding health challenges also advanced, with significant progress towards a cost-effective blood test for detecting Alzheimer’s disease, aiming for integration into the UK’s public health system.

2024: A Landmark Year for Science and Environmental Awareness

### Significant Scientific Achievements

The year 2024 has marked a pivotal moment in scientific research and environmental awareness, showcasing groundbreaking discoveries and urgent calls for action against climate change. Here’s a closer look at the key advancements and trends shaping the current landscape.
