Scientific achievements in 2021 took on global challenges, from public health to environmental issues and technology. The rollout of vaccines helped fight the pandemic.
Researchers pushed boundaries in brain-computer interfaces and space exploration, opening fresh doors for discovery. Collaboration across countries really stood out as essential for tackling shared problems.
The year also brought big steps in sustainable solutions and emerging tech. People found creative ways to fight climate change, turn waste into resources, and tap into new energy sources.
These advances showed how science and innovation can genuinely make life better and shape what comes next.
Key Takeaways
- Science drove solutions for global challenges.
- Technology opened new possibilities in research.
- International collaboration pushed innovation forward.
Tackling the Challenges of COVID-19
The fight against COVID-19 kept going in 2021, with the world trying to minimize its impact. By November, the virus had taken five million lives, a staggering loss.
New variants showed up, like Delta, causing more severe illness and spreading quickly. Then Omicron came along, moving even faster and straining public health systems further.
Researchers responded with a wave of medical solutions. They brought out mRNA vaccines, inactivated vaccines, and recombinant vaccines that helped prevent severe cases and cut down hospitalizations.
Neutralizing antibodies and oral antiviral medicines also joined the fight, reducing deaths and critical cases. Still, the need for ongoing effort is obvious—there’s no quick fix for a pandemic of this scale.
Exploring Samples from Space
Space exploration hit new heights as scientists gathered material from distant worlds. NASA’s Perseverance rover started collecting Martian rocks, with a plan to bring them to Earth sometime in the next decade.
These samples could reveal a lot about Mars’ ancient environment. China notched a milestone too, becoming the second country to land on Mars with Tianwen-1.
The Chang’e-5 mission brought back lunar samples that showed volcanic activity on the moon happened as recently as 2 billion years ago. That’s a surprise—most people thought the moon cooled off much earlier.
Japan’s Hayabusa 2 returned samples from asteroid Ryugu, and early results hint these could be some of the oldest stuff we’ve ever studied. The Parker Solar Probe even dipped into the sun’s upper atmosphere, scooping up particles and magnetic field data for the first time.
Climate Challenges and Solutions
Extreme weather keeps getting worse and more common, a sign of global warming’s reach. Floods, megafires, and wild storms keep testing our limits.
Arctic temperatures are rising four times faster than the world average, which is honestly alarming. Scientists think we could hit the 1.5°C warming mark by the early 2030s, making serious action even more urgent.
People are pushing for renewable energy and better energy efficiency. New ideas are paving the way to carbon neutrality.
But it’s not just about gadgets—social, financial, and policy changes matter too. Platforms like COP26 spark debate about emissions cuts and climate reparations, though it’s fair to ask if these promises are bold enough.
Predicting Protein Structures
Artificial intelligence (AI) is shaking up how we study proteins. Tools like AlphaFold and RoseTTAFold can predict 3D protein structures from just amino acid sequences, which used to take labs months to figure out.
AlphaFold, from DeepMind, nailed the structure for 98.5% of human proteins, giving research a massive boost. RoseTTAFold, out of Seattle, is helping us understand how proteins interact.
Both teams made their data publicly accessible, so scientists worldwide can join in. This kind of open sharing really shows how machine learning can speed up science.
Transforming Waste Materials Into Resources
Researchers are getting creative with new methods to turn waste into useful stuff. One standout is artificial starch production, where they use carbon dioxide and catalysts to make starch eight times faster than plants do it naturally.
This could mean more sustainable manufacturing, less farmland needed, and a smaller carbon footprint. Industries that depend on starch might really benefit, and it’s a promising step for food security and climate challenges.
Fusion as the Energy of Tomorrow
Nuclear fusion made some real headway, hinting at a future energy solution. The two main approaches—magnetic confinement and inertial confinement—both chase the holy grail of “ignition,” where you get out more energy than you put in.
In May 2021, China’s Experimental Advanced Superconducting Tokamak (EAST) kept things at 120 million degrees Celsius for 101 seconds, breaking South Korea’s previous record. That’s a big leap in how long we can hold those crazy temperatures.
The National Ignition Facility (NIF) in the US also made news in August by generating 1.3 megajoules of energy with 1.9-megajoule lasers. It’s a sign we’re inching closer to self-sustaining fusion, though there’s still a long way to go.
Large Telescopes Pushing Scientific Boundaries
Astronomy and physics got a boost with the launch of the James Webb Space Telescope. After nearly thirty years and $10 billion, it’s finally peering at the universe’s earliest light.
China’s Large High Altitude Air Shower Observatory (LHAASO) is changing the game for high-energy particle studies. From its spot on the Tibetan Plateau, it caught the most energetic light particle ever, from 4,600 light years away.
The Five-hundred-meter Aperture Spherical Radio Telescope (FAST) found over a thousand rapid radio bursts, helping us piece together the universe’s weirdest mysteries. There’s still so much out there we don’t understand.
Mystery of the Dragon-Era Skull
The Homo longi skull—nicknamed Dragon Man—has shaken up how we see human evolution. Found in Harbin, northeast China, it’s one of the most complete early human fossils ever discovered.
It’s got these prominent brow ridges, big eye sockets, and teeth that are just massive. Experts say the man lived more than 146,000 years ago, adding a new twist to our story.
Some research even hints Dragon Man might be closer to us (Homo sapiens) than Neanderthals are. That’s a wild thought and opens up all sorts of questions about our ancient relatives.
Interfaces Connecting the Brain and Technology
Brain-computer interfaces, or BCIs, have taken some wild leaps forward lately. Invasive approaches, like placing micro-electrode arrays directly in the brain, have led to some almost sci-fi results.
Neuralink, for instance, showed a monkey playing video games just by thinking—thanks to a microchip implanted in its brain. Over at Stanford, researchers managed to help a paralyzed person compose text by simply thinking about specific letters.
There’s a lot left to figure out, though. We need to understand brain functions better, improve how we record and decode signals, and shrink these chips down even more.
And, honestly, the ethical questions are huge. We have to make sure we’re not running faster than we can handle with this tech.
If things go well, all these breakthroughs could totally change how we connect with machines and how accessible tech becomes for folks who need it. (More here.)
Expanding Free Access to Research
Open access has become a much bigger deal lately, especially after the COVID-19 pandemic made everyone realize how crucial it is to get scientific info fast. In 2021, open-access publishing picked up speed, with new platforms and policies opening the doors to more people.
The European Commission, for example, launched Open Research Europe so researchers funded by Horizon 2020 and Horizon Europe could share their results right away. That’s a pretty big step for collaboration across different fields.
Something pretty major happened in the U.S. too: the Howard Hughes Medical Institute said all its lab heads had to publish research as open access starting January 2022. This shift lined up with the 20th anniversary of the Budapest Open Access Initiative, which really set the stage for free access to research in the first place.
