IVF Success Rates: Can New Research Improve the Odds?
While in vitro fertilization (IVF) has been a revolutionary infertility treatment since the birth of Louise Brown, the first baby conceived through the procedure in 1978, many couples still face a long and uncertain journey toward parenthood. Despite advancements in IVF techniques, the live birth rate per embryo transfer remains low for many patients. New research may hold the key to improving these odds.
IVF begins with a delicate process where eggs are fertilized outside the body and observed as they develop into embryos. Some fertility clinics offer a high-tech procedure known as time-lapse imaging, where embryos are photographed every ten minutes to monitor their progress. This technique, often presented as a way to increase the chances of a successful pregnancy, has become widely used and expensive—adding up to $700 in the UK or $500 in the US to an IVF cycle.
However, a study published in The Lancet in July 2024 cast doubt on the benefits of time-lapse imaging. The study, which reviewed over 1,500 IVF procedures, found no significant difference in live birth rates between those using time-lapse imaging and those who did not. Priya Bhide, a senior lecturer at Queen Mary University of London, who co-authored the study, noted that previous reviews had already suggested limited evidence for the technique’s effectiveness.
Despite the lack of clear improvements from time-lapse imaging, the broader field of IVF has made incremental progress over the years. For example, the success rate of IVF has tripled for women under 38 since the 1990s, and the live birth rate in the US has risen 1.6 times over the past decade. Still, for women aged 35 and older, the success rate per embryo transfer remains relatively low, around 30-39%.
The emotional and financial toll of IVF can be severe, with many patients undergoing multiple cycles, each costing thousands of dollars, and facing repeated failures. However, researchers are hopeful that new approaches could increase the chances of success.
One promising area of research is the development of better techniques for egg extraction. A new method being tested on dairy cows uses a specially designed needle that induces fluid turbulence inside the follicle to extract more eggs without damaging them. If successful in human trials, this technique could increase both the quantity and quality of retrieved eggs, potentially improving IVF outcomes.
Additionally, scientists in Spain are experimenting with magnetic nanoparticles that allow for the manipulation of eggs and embryos without direct physical contact. This method could reduce the risk of damaging delicate cells, which is a common concern in IVF procedures.
In Australia, researchers are investigating the use of light to measure lipid levels in embryos, which could offer new insights into their metabolic activity and potential for successful development. However, as with all new technologies, these methods still need extensive testing before they can be applied in clinical practice.
While IVF continues to offer hope for millions, researchers caution that even with new innovations, the road to a successful pregnancy remains uncertain. As IVF becomes more advanced, the challenge remains to make these techniques more effective and accessible, while managing the emotional and financial strain for couples.

Chinese Memes Take Over American Social Media Amid Rising Tech Tensions
Despite growing tensions between the United States and China over national security and trade, Chinese internet culture is experiencing an unexpected surge in popularity among American social media users. From viral memes about industrial chemicals to an influx of U.S. users on Chinese platforms, the digital space has become an unlikely bridge between the two nations.
One of the most surprising trends of 2024 was the rise of Donghua Jinlong, a Hebei-based manufacturer of industrial glycine, an amino acid used in food production. Though an obscure company, its advertisements on TikTok unexpectedly went viral, transforming the brand into an internet sensation. American users, dubbing themselves “glycine girlies,” embraced the meme, creating influencer-style content about a product they had no actual use for.
Diana R., the creator behind the popular meme account CitiesbyDiana, explained the phenomenon. “We spent an entire month pretending we were buying industrial chemicals from China and making videos as if it were a luxury brand,” she said. The meme became so widespread that it was covered by major publications, including The Washington Post and The New Yorker. Donghua Jinlong even played along, sending merchandise to online creators.
TikTok Ban Sparks Migration to RedNote
The viral fascination with Chinese memes coincides with a new wave of American users flocking to RedNote (Xiaohongshu), China’s version of Instagram. This sudden migration was triggered by the brief implementation of a TikTok ban over national security concerns, before President Donald Trump granted the platform a 75-day reprieve.
In just a few days, around three million Americans joined RedNote, integrating into a platform with 300 million predominantly Chinese users. The result was an unexpected cultural exchange, as users swapped jokes, shared memes, and even helped each other with homework.
American internet users have long speculated about what lies beyond China’s “Great Firewall”, which restricts access to many Western social media platforms. But RedNote has emerged as one of the few Chinese apps accessible overseas, allowing U.S. users to engage with Chinese netizens in a way that was previously rare.
A Cultural Exchange Beyond Politics
Even as U.S. leaders push for restrictions on Chinese tech companies, internet culture appears to be bridging the geopolitical divide. One of the most popular viral phrases to emerge from RedNote is “you swan, he frog,” a Chinese idiom originally used to describe relationships with mismatched expectations. After being posted by an American influencer, it quickly spread across English-speaking social media, applied to everything from celebrities to politicians.
The rise of Chinese memes in the U.S. reflects a growing curiosity about Chinese internet culture, despite political narratives urging division. Jianqing Chen, an East Asian languages and cultures researcher at Washington University in St. Louis, believes social media plays a crucial role in fostering connections between everyday citizens. “Grand political narratives lose their power at the level of everyday interaction,” he said. “Personal engagement online allows people to see beyond tensions and recognize shared human experiences.”
Even amid discussions of trade wars and national security threats, social media continues to show that humor—and memes—transcend borders.

DeepSeek’s Rise Shakes AI Industry, Sends Shockwaves Through US Tech Sector
A new AI app from China, DeepSeek, has sent shockwaves through the tech industry, markets, and the prevailing belief in American dominance in artificial intelligence (AI). The app’s meteoric rise has raised questions about the future of the AI sector, as well as the cost-effectiveness of AI development.
Venture capitalist Marc Andreessen referred to the launch of DeepSeek as AI’s “Sputnik moment,” drawing comparisons to the Soviet Union’s launch of the Sputnik satellite, which triggered the space race. Over the weekend, DeepSeek became the most downloaded free app on Apple’s US App Store, and by Monday, it was already having a profound effect on the markets. The app’s launch sparked a massive sell-off of major tech stocks, including a 17% plunge in the share price of AI chipmaker Nvidia, which lost nearly $600 billion in market value — the largest drop in US stock market history, according to Bloomberg.
What has stunned Silicon Valley is the claim by DeepSeek’s developers that the app was built for just $5.6 million — a fraction of the billions spent by AI giants like OpenAI, Google, and Anthropic. While OpenAI spent $5 billion in 2023 alone, DeepSeek’s developers suggest that this low cost could signal a breakthrough in AI development, potentially disrupting the established industry.
In a growing sense of disbelief, many in the tech world have been left questioning DeepSeek’s viability and the accuracy of its financial claims. Some analysts have speculated that the app’s success could indicate a shift in how AI is developed and delivered, with lower costs and fewer resources than previously thought necessary. DeepSeek’s models reportedly use open-source software and existing technology, which has led some to speculate that its use of Nvidia’s H800 chips may have been facilitated by stockpiling during the past years.
The development has also spurred concerns about US dominance in the sector, as the country has long assumed its control over high-end chips and data centers gave it an advantage in the AI race. However, China’s sudden emergence as a serious player with DeepSeek has led many to reconsider the global balance of power in AI.
Billionaire Sam Altman of OpenAI, who has largely stayed quiet on the matter, did comment late on Monday, acknowledging DeepSeek’s “impressive” performance. While Altman reaffirmed OpenAI’s position as a leader in AI, he welcomed the competition, calling it invigorating.
DeepSeek’s arrival has left many observers unsure of what the future holds for US semiconductor giants and raised broader questions about the long-term implications of AI development. With this new development, China has flexed its muscles in the AI sector, making clear that the race for dominance is far from over, and the US may no longer have a clear upper hand.
