Scientific discoveries and technological innovation play a vital role in addressing many of the challenges and crises that we face every year.

The last year may have come and gone quickly, but scientists and researchers have worked painstakingly hard to advance our knowledge within a number of disciplines, industries, and projects around the world.

Over the course of 2022, it’s easy to lose track of all the amazing stories in science and technology.

At a Glance: Major Scientific Headlines of 2022

Below we dive a little deeper into some of the most interesting headlines, while providing links in case you want to explore these developments further.

January 2022

The James Webb Space Telescope Arrives at its Destination

What happened: A new space telescope brings promise of exciting findings and beautiful images from the final frontier. This telescope builds on the legacy of its predecessor, the Hubble Space Telescope, which launched over 30 years ago.

Why it matters: The James Webb Space Telescope is our latest state-of-the-art “window” into deep space. With more access to the infrared spectrum, new images, measurements, and observations of outer space will become available.

May 2022

Monkeypox Breaks Out

What happened: A higher volume of cases of the monkeypox virus was reported in non-endemic countries.

Why it matters: Trailing in the shadow of a global pandemic, researchers are keeping a closer eye on how diseases spread. The sudden spike of multinational incidences of monkeypox raises questions about disease evolution and prevention.

August 2022

Dead Organs Get a Second Chance

What happened: Researchers create a perfusion system that can revitalize organs after cellular death. Using a special mixture of blood and nutrients, organs of a dead pig can be sustained after death—and in some cases, even promote cellular repair.

Why it matters: This discovery could potentially lead to a greater shelf-life and supply of organs for transplant.

September 2022

DART Delivers A Cosmic Nudge

What happened: NASA crashes a spacecraft into an asteroid just to see how much it would move. Dimorphos, a moonlet orbiting a larger asteroid called Didymos 6.8 million miles (11 million km) from Earth, is struck by the DART (Double Asteroid Redirection Test) spacecraft. NASA estimates that as much as 22 million pounds (10 million kg) was ejected after the impact.

Why it matters: Earth is constantly at risk of being struck by stray asteroids. Developing reliable methods of deflecting near-Earth objects could save us from meeting the same fate as the dinosaurs.

November 2022

Falling Sperm Counts

What happened: A scientific review suggests human sperm counts are decreasing—up to 62% over the past 50 years.

Why it matters: A lower sperm count makes it more difficult to conceive naturally. Concerns about global declining male health also arise because sperm count is a marker for overall health. Researchers look to extraneous stressors that may be affecting this trend, such as diet, environment, or other means.

December 2022

Finding Ancient DNA

What happened: Two million-year-old DNA is found in Greenland.

Why it matters: DNA is a record of biodiversity. Apart from showing that a desolate Arctic landscape was once teeming with life, ancient DNA gives hints about our advancement to modern life and how biodiversity evolves over time.

December 2022

Fusing Energy

What happened: The U.S. Department of Energy reports achieving net energy gain for the first time in the development of nuclear fusion.

Why it matters: Fusion is often seen as the Holy Grail of safe clean energy, and this latest milestone brings researchers one step closer to harnessing nuclear fusion to power the world.

Science in the New Year

The future of scientific research looks bright. Researchers and scientists are continuing to push the boundaries of what we know and understand about the world around us.

For 2023, some disciplines are likely to continue to dominate headlines:

  • Advancement in space continues with projects like the James Webb Space Telescope and SETI COSMIC’s hunt for life beyond Earth
  • Climate action may become more demanding as recovery and prevention from extreme weather events continue into the new year
  • Generative AI tools such as DALL-e and ChatGPT were opened to public use in 2022, and ignited widespread interest in the potential of artificial intelligence
  • Even amidst the lingering shadow of COVID-19, new therapeutics should advance medicine into new territories

Where science is going remains to be seen, but this past year instills faith that 2023 will be filled with even more progress.

Did you know that some computer chips are now retailing for the price of a new BMW?

As computers invade nearly every sphere of life, so too have the chips that power them, raising the revenues of the businesses dedicated to designing them.

But how did various chipmakers measure against each other last year?

We rank the biggest semiconductor companies by their percentage share of the industry’s revenues in 2023, using data from Omdia research.

Which Chip Company Made the Most Money in 2023?

Market leader and industry-defining veteran Intel still holds the crown for the most revenue in the sector, crossing $50 billion in 2023, or 10% of the broader industry’s topline.

All is not well at Intel, however, with the company’s stock price down over 20% year-to-date after it revealed billion-dollar losses in its foundry business.

Meanwhile, Nvidia is very close to overtaking Intel, after declaring $49 billion of topline revenue for 2023. This is more than double its 2022 revenue ($21 billion), increasing its share of industry revenues to 9%.

Nvidia’s meteoric rise has gotten a huge thumbs-up from investors. It became a trillion dollar stock last year, and broke the single-day gain record for market capitalization this year.

Other chipmakers haven’t been as successful. Out of the top 20 semiconductor companies by revenue, 12 did not match their 2022 revenues, including big names like Intel, Samsung, and AMD.

The Many Different Types of Chipmakers

All of these companies may belong to the same industry, but they don’t focus on the same niche.

According to Investopedia, there are four major types of chips, depending on their functionality: microprocessors, memory chips, standard chips, and complex systems on a chip.

Nvidia’s core business was once GPUs for computers (graphics processing units), but in recent years this has drastically shifted towards microprocessors for analytics and AI.

These specialized chips seem to be where the majority of growth is occurring within the sector. For example, companies that are largely in the memory segment—Samsung, SK Hynix, and Micron Technology—saw peak revenues in the mid-2010s.
