Human Intelligence Sharply Declining
No, it's not just you — people really are less smart than they used to be.
As the Financial Times reports, assessments show that people across age groups are having trouble concentrating and losing reasoning, problem-solving, and information-processing skills — all facets of the hard-to-measure metric that "intelligence" is supposed to measure.
These results, the FT reports, are gleaned from benchmarking tests that track cognitive skills in teens and young adults. From the University of Michigan's Monitoring the Future study documenting concentration difficulties of 18-year-old Americans to the Programme for International Student Assessment (PISA) that measures the learning skills of 15-year-olds around the world, years of research suggest that young people are struggling with reduced attention spans and weakening critical thinking skills.
Though there has been a demonstrably steep decline in cognitive skills since the COVID-19 pandemic due to the educational disruption it presented, these trends have been in evidence since at least the mid-2010s, suggesting that whatever is going on runs much deeper and has lasted far longer than the pandemic.
Obviously, there's no single answer as to why people seem to be struggling with cognitive skills, but one key indicator is the sharp decline in reading and the world's changing relationship to the way we consume information and media. In 2022, for example, the National Endowment for the Arts found that just 37.6 percent of Americans said they'd read a novel or short story in the year prior — a share down from 41.5 percent in 2017 and 45.2 percent in 2012.
It would be easy enough to blame this decline on people reading less (and, presumably, scrolling online brainrot more). But according to 2023 results from the Organization for Economic Co-operation and Development, the same international consortium that puts out the PISA survey, 34 percent of adults in the United States scored at the lowest levels of numeracy, which essentially means that they lack the ability to work with numbers. A year prior, that share was just 29 percent.
Beyond changes in media consumption and the mediums in which we take it, it appears, as the FT notes, our relationship to information generally is shifting too. While there certainly are ways to use tech that don't cause harm to cognition, studies show that "screen time" as we know it today hurts verbal functioning in children and makes it harder for college-age adults to concentrate and retain information.
There isn't any reason to suggest that human intellect has been harmed, the publication counters — but in "both potential and execution," our intelligence is definitely on the downturn.

Eating more of these plant-based foods could lower your risk of heart disease and diabetes
Eating more nuts, fruits, vegetables, and whole grains may help to reduce your risk of contracting deadly heart disease and type 2 diabetes. Researchers said this week that people who consumed more phytosterols — a natural compound found in plant foods — significantly delayed both of the conditions. Furthermore, eating more of them was linked to reduced inflammation, markers of better insulin regulation, and differences in the gut microbiome that may contribute to healthy metabolism. The study was not designed to confirm why this is the case, but the researchers said their findings strengthen the evidence. More than 7000,000 Americans die from heart disease and some 101,000 die from diabetes. 'Our findings support the dietary recommendation of adhering to healthy plant-based dietary patterns that are rich in vegetables, fruits, nuts and whole grains,' Dr. Fenglei Wang, a research associate at the Harvard T.H. Chan School of Public Health, said in a statement. 'These findings can help people make informed dietary choices.' Wang presented the observational findings on Tuesday at the flagship annual meeting of the American Society for Nutrition. Some phytosterol-rich foods include corn, almonds, broccoli, bananas, and wheat bread. Previous research had found that eating foods with phytosterols can help to improve peoples' health by lowering bad cholesterol, and may reduce the risk of cancer. However, most clinical trials have used high doses of the phytosterols that were beyond what someone might get through just their own diet. The new research is the first to show the benefits as part of a normal diet. To reach these conclusions, Wang and his colleagues looked at data from more than 200,000 American adults that were a part of three studies. All of the participants were nurses or other health professionals and nearly 80 percent were women. Over the course of 36 years, more than 20,000 of them developed type 2 diabetes and nearly 16,000 developed heart disease. The participants' answers to food-frequency questionnaires allowed the researchers to estimate their individual intake of phytosterols, as well as three individual phytosterols known as β-sitosterol, campesterol and stigmasterol. Those who ate the most consumed the most phytosterol had about four to five servings of vegetables, two to three servings of fruits, two servings of whole grains, and half a serving of nuts each day. This made them 9 percent less likely to develop heart disease and 8 percent less likely to develop type 2 diabetes compares to those in the bottom fifth percentage for phytosterol intake, the research showed. Looking at the individual phytosterols, similar associations were observed for β-sitosterol. But, the same was not true for campesterol or stigmasterol. In addition, the researchers analyzed blood samples, looking at the products of metabolism — also known as metabolites — from more than 11,000 people and other metabolic biomarkers in blood samples from over 40,000 participants. They found that phytosterol and β-sitosterol levels were tied to favorable metabolites and metabolic markers relevant to heart disease and diabetes. That signaled a possible reason for the association. 'Our clinical biomarker and metabolomic results suggest the involvement of insulin activity, inflammation and the metabolism of metabolites associated with type 2 diabetes and cardiovascular disease,' said Wang. 'This suggests that phytosterol might reduce risk by alleviating insulin resistance and inflammation.' In a group of just 465 participants, they examined the gut microbiome, or the trillions of microscopic organisms inside the intestines. They found several microbial species and related enzymes linked to higher intake of phytosterols that may affect the production of metabolites associated with a lower risk of diseases. 'We found that the gut microbiome might play a role in the beneficial associations. Some species, such as Faecalibacterium prausnitzii, carry enzymes that could help degrade phytosterol, potentially influencing host metabolism,' Wang said.

Nucleus Genomics Launches Nucleus Embryo, Genetic Optimization Software Alongside Partnership with Genomic Prediction
Parents pursuing IVF now have a new level of choice to empower their family planning NEW YORK, June 4, 2025 /PRNewswire/ -- With U.S. birthrates plummeting and IVF on the rise, Nucleus Genomics today launched Nucleus Embryo, the first genetic optimization software that lets parents see and understand a complete genetic profile to select an embryo. "Before there's a heartbeat, there's DNA," said Kian Sadeghi, founder and CEO of Nucleus. "One file containing DNA and genetic markers can tell you more about your baby's future than any other test a doctor could possibly run at this stage. Most clinics stop at whether an embryo will develop. For many parents, that's not enough. Patients have long asked for more transparency from clinics, and Nucleus Embryo is an important step toward complete data ownership for parents planning their families." The software enables parents to analyze and compare up to 20 embryos across over 900 hereditary conditions and 40 additional analyses beyond basic viability, spanning cancers, chronic conditions, appearance, cognitive ability, mental health, and more. To widen access to the software, Nucleus will partner with Genomic Prediction, the first company to offer genome-wide screening on embryos. The partnership sets a new standard in genetic medicine, continuing Genomic Prediction's decade-long history of giving hopeful parents the best possible chance of implanting healthy embryos. The company's analyses focus on hereditary conditions, acting as the first line of defense against chronic and rare diseases. "As an organization, we are committed to supporting patients' rights to their DNA and any information that can aid in their family-building journey," said Kelly Ketterson, CEO of Genomic Prediction. "We have a legacy of innovation aimed at providing patients with access to the best scientific resources. Our partnership with Nucleus opens access to information our patients have requested and allows us to uphold our commitment to this legacy." Nucleus' partnership with Genomic Prediction reflects a growing shift in how parents think about genetics as a tool to give children the best possible start in life. A wide-ranging study of Americans found the majority accepted the use of genetic technology to choose embryos based on health and personality traits. Four in 10 parents would use genetic optimization as another tool to understand their future child's cognitive abilities. Most women undergo three to six IVF cycles before successfully having a baby, with each cycle costing up to $25,000. Many embryos are unviable within days of being fertilized, leaving parents with few to choose from. Facing high stakes, clinicians often recommend genetic testing to optimize a couple's chances of a healthy pregnancy. But these tests typically stop at a select number of hereditary conditions and chromosome count. Now, advanced genetic analysis from Nucleus gives parents a new window into the health and well-being of their future child. Nucleus Embryo provides a comprehensive genetic profile for each embryo, encompassing hereditary genetic diseases, like cystic fibrosis and hemochromatosis, alongside genetic measures of cognitive ability, mental health, and risk for chronic diseases. Wide access to genetic insights for embryos can also help extend lifespan from the earliest stages of life. While more than half of all deaths annually in the U.S. are attributed to chronic, age-related conditions — such as Alzheimer's disease, diabetes, cancer, and heart disease — research shows embryonic selection can materially help reduce disease risk for these conditions. "We celebrate health optimization and the pursuit of longevity in every other part of life via our focus on training, supplements, and sleep," Sadeghi said. "We all know health isn't just the absence of disease. It's the ability to understand our bodies and genetic makeup to reach our full potential. Now we can apply this principle to life's inception." About Nucleus Genomics Nucleus builds software for generational health. Inspired by the loss of his cousin who died of a rare — yet preventable — genetic disease, Nucleus founder and Thiel Fellow Kian Sadeghi left an Ivy League university to build a product that could have saved her life. Our advanced DNA health test and analysis takes the guesswork out of your health, whether it's perfecting your protocols, knowing your risk for cancer, or planning for a healthy family. Follow us on social media @nucleusgenomics. About Genomic Prediction Genomic Prediction, Inc. is the frontrunner in advanced embryo screening. Our proprietary LifeView platform is state-of-the-art technology that assesses embryos for genetic health aimed at improved IVF outcomes. The LifeView Embryo Health Score Test (EHS) offers insight into the likelihood of developing conditions driven by multiple genes. It tests for significant health issues, including cardiovascular disease, diabetes mellitus, certain cancers, and mental health conditions. The EHS results are derived from the same embryo sample used in the following PGT tests: PGT-A: Identifies chromosome abnormalities in embryos. PGT-A+: Pinpoints the origin (paternal, maternal, or embryonic) of chromosome abnormalities. PGT-M: Decreases the chances of passing on monogenic (single-gene) conditions. PGT-SR: Detects chromosome abnormalities and structural imbalances, providing clarity between normal and balanced chromosomes. View original content to download multimedia: SOURCE Nucleus

New coronavirus discovered in China ‘only small step' from infecting humans
A new coronavirus discovered in China is only a small step from mutating and causing another global pandemic, experts have warned. Scientists believe the variant, called HKU5-CoV-2, may infect a broader range of animals than Covid-19 – which caused millions of deaths – and may have more potential for jumping between species. US researchers fear that HKU5-CoV-2, found in China, in February, could also infect humans, leading to a widespread outbreak. The new study, published in Nature Communications, looked at a lesser-known group of coronaviruses called merbecoviruses, which includes HKU5 and MERS-CoV, which is responsible for the deadly Middle East Respiratory Syndrome. The team from Washington State University looked at how the new pathogen interacts with human cells. They found that a small change in the virus's spike protein could allow it to attach to human ACE2 cells in people's throats, mouths and noses. HKU5-CoV-2 can infect and replicate inside human cells in both the airways and gut. According to the World Health Organisation, about 35 per cent of people infected with Middle East Respiratory Syndrome die. Since 2012, some 27 countries have reported cases, leading to 858 known deaths due to the infection, which spread from camels. But when HKU5 was discovered in February, scientists warned against exaggerating the risks because it does not enter human cells as readily as Sars-CoV-2, which caused Covid-19. HKU5 was first detected in bats by scientists from the Chinese laboratory where some say Covid originated in 2019. Prof Michael Letko, a virologist who co-led the study, said: 'HKU5 viruses in particular really hadn't been looked at much, but our study shows how these viruses infect cells. 'What we also found is HKU5 viruses may be only a small step away from being able to spill over into humans.' When Covid-19 emerged it was widely blamed on markets in China where different breeds of wild animal are kept caged and often slaughtered close to other animals. Meat is sold at the open-air stalls. Critics said the markets were the perfect breeding ground for new zoonotic diseases – those that spread to humans – to emerge. The scientists, whose experiments studied how the new pathogen interacts with human cells, believe the virus would have to carry certain mutations if it were to infect humans. 'These viruses are closely related to MERS, so we have to be concerned if they ever infect humans,' Prof Letko said. 'While there's no evidence they've crossed into people yet, the potential is there and that makes them worth watching.'
