2024: A Breakthrough Year for Science and Discovery

The year 2024 has been an extraordinary one for scientific advancements and groundbreaking discoveries. From medicine and space exploration to genetics and archaeology, researchers have pushed the boundaries of human knowledge. Here’s a look at some of the most remarkable achievements of the year.

Medical Innovations

Lenacapavir: A Game-Changer in HIV Prevention

Initially approved in 2022, Lenacapavir demonstrated outstanding success in 2024 trials, with a 96% success rate in one study and a perfect 100% in another. This semi-annual injection serves as a pre-exposure prophylaxis (PrEP) against HIV, offering new hope in the fight against the virus.

DermaSensor: Revolutionizing Skin Cancer Detection

The DermaSensor, developed at Boston University, uses advanced light-based technology to distinguish between malignant and benign skin lesions. FDA-approved in January, it was later recognized as one of Time’s "Inventions of the Year" for its potential to significantly reduce missed cancer diagnoses.

AI Predicts Alzheimer’s Progression

A machine learning model developed by Boston University experts achieved an accuracy rate of 78.5% in predicting the transition from mild cognitive impairment to Alzheimer’s. This breakthrough could lead to earlier interventions and improved patient outcomes.

Breakthroughs in Genetics and Evolution

CRISPR Technology Advances

CRISPR gene editing continues to evolve, with researchers at Profluent developing OpenCRISPR-1, an open-source tool powered by AI. This innovation aims to enhance gene-editing accuracy and safety while addressing ethical concerns.

Neanderthal-Human Interbreeding Timeline Uncovered

Genetic studies analyzing ancient and modern human genomes have pinpointed the period of coexistence between Neanderthals and humans in Eurasia to 50,500–43,500 years ago. This discovery helps clarify the timeline of interbreeding and shared ancestry.

Astrophysical Discoveries

New Super-Earth: TOI-715 b

NASA identified TOI-715 b, a super-Earth 137 light-years away, located within a habitable zone where liquid water could exist. Additionally, evidence suggests the presence of a smaller, Earth-like planet in the same system.

Three New Moons Found Orbiting Neptune and Uranus

The discovery of three additional moons brings Neptune’s and Uranus’s total moon count to 30, expanding our understanding of the outer solar system.

Space Cloud’s Impact on Earth’s Climate

Researchers found that a dense interstellar cloud, encountered by our solar system two million years ago, may have compressed the sun’s heliosphere, reducing Earth's protection and triggering a temperature drop.

Breakthroughs in Biology and Earth Sciences

Fruit Fly Brain Mapping

After a decade of research, scientists completed a detailed map of 140,000 neurons in a fruit fly’s brain. This milestone enhances our understanding of human cognition and memory processes.

Deep-Sea Rocks Generating Oxygen

Researchers discovered that polymetallic nodules in the Pacific Ocean can generate oxygen through seawater electrolysis, challenging previous beliefs that oxygen production required sunlight-driven organisms.

Oldest Known Reptile Skin

A 20-million-year-old fossilized reptile skin was unearthed in 2024, providing unprecedented insights into ancient semi-aquatic lifeforms, possibly belonging to Captorhinus aguti.

Archaeological and Historical Discoveries

Ancient Cave Art in Patagonia

Scientists uncovered nearly 900 pigmented cave paintings in Cueva Huenul 1, Argentina, some dating back 8,200 years. These intricate designs, depicting human faces, geometric shapes, and llama-like creatures, suggest the cave was a cultural learning center for over 100 generations.
