The past eighteen months have been a period of remarkable progress across numerous scientific disciplines, offering both hope and critical insights into our world and beyond. From advancements in supercomputing power-with the inauguration of the exascale El Capitan-to increasingly urgent data regarding planetary health, researchers have been pushing the boundaries of known science. This report details seven key breakthroughs from 2024 and early 2025, including potential progress towards an HIV cure and tantalizing evidence in the search for life on Mars, developments that could reshape our understanding of medicine, the universe, and our place within it.
Atlanta –
The year 2024 and the beginning of 2025 have brought a wave of significant scientific advancements, ranging from the discovery of new species and the reappearance of previously rare ones to groundbreaking findings in our understanding of dinosaurs and the universe. These developments offer new insights into our world and beyond, with potential implications for human health and our planet’s future.
Here’s a look at some of the most notable scientific breakthroughs of the past year:
7 Key Scientific Discoveries of 2024 & 2025
Table of Contents
1. The World’s Fastest Supercomputer
In January, the world’s fastest supercomputer was inaugurated at Lawrence Livermore National Laboratory in California. Named El Capitan, the computer is the third to ever achieve exascale computing speed, boasting a peak performance of 2.79 exaFLOPS – or 2.79 quintillion calculations per second.

The supercomputer will be used to maintain the U.S. nuclear weapons stockpile and research the design of new nuclear weapons. Construction began in May 2023, with a cost of $600 million at that time.
2. Planetary Boundaries Under Pressure
Data revealed in January showed that 2024 was the first calendar year on record with a global average temperature 1.6°C (2.8°F) above pre-industrial levels. This finding came nearly a decade after 195 countries adopted the Paris Climate Agreement, committing to steps to limit global warming to 1.5°C above pre-industrial averages.
Later in the year, in June, scientists announced that ocean acidification had surpassed a planetary boundary – the seventh of nine such boundaries exceeded since 2009. Crossing all nine boundaries could trigger widespread environmental collapse.
3. A Potential Breakthrough in HIV Treatment
Progress toward a potential cure for HIV emerged in May when researchers in Melbourne, Australia, announced they had found a way to force the virus out of human cells. A major challenge in HIV treatment has been the virus’s ability to hide within white blood cells, allowing it to reactivate at any time.
The researchers utilized mRNA technology to make the virus visible, a feat previously considered impossible. This discovery could have implications for treating other diseases involving white blood cells, including cancer.
Currently, nearly 40 million people worldwide live with HIV and require medication to suppress the virus and prevent transmission.
4. Hints of Life on Mars
A detailed study of ‘dark spots’ on a Martian rock revealed patterns that researchers believe are the most compelling evidence of life ever found on Mars, according to NASA Acting Administrator Sean Duffy in September.
The rock, estimated to be around 3.5 billion years old, was discovered by NASA’s Perseverance rover during its exploration of Jezero Crater in July 2024. Scientists believe the markings may originate from ancient microbes on Mars.
Since then, planetary scientists have been working to determine the cause of these markings.
5. Neutrino Scattering Observed
After 50 years of searching, an effect involving neutrinos – fundamental particles – was finally observed in July. First theorized in 1974, coherent elastic neutrino-nucleus scattering (CEvNS) involves neutrinos scattering coherently off atomic nuclei in a nuclear reactor, creating a very small nuclear recoil.
Scientists explained that measuring this effect is akin to trying to determine the change in motion of a moving car after bouncing a ping pong ball off it. A detector in Switzerland has now captured CEvNS with unprecedented clarity. This detector could have powerful applications, including the discovery of new forces or particles that interact only with neutrinos.
6. First-Ever Recording of Human Embryo Implantation
For the first time, the moment a human embryo implants itself into an artificial womb was captured on camera in September. Researchers who took the images hope to contribute to a better understanding of the process and potentially improve fertility outcomes, both in natural conception and in vitro fertilization (IVF).
7. The Slowing Universe
Consistent with previous theories, the universe is expanding. However, it has now been observed that the rate of expansion is gradually slowing down.
In June, members of the Supernova Cosmology Project published a new analysis that appears to reinforce findings from March. If the expansion of the universe is indeed slowing, the consequences would be significant, potentially requiring scientists to revisit the established standard model of particle physics.
Furthermore, this trajectory suggests a possible new scenario for the end of the universe – a dramatic ‘Big Crunch’ where expansion reverses and the entire cosmos collapses.
