Surgeons in China have successfully transplanted a genetically modified pig lung into a brain-dead human recipient, where it remained functional for nine days. The procedure, reported in Nature Medicine, represents a major milestone in xenotransplantation—a field aimed at addressing the global shortage of donor organs. According to the World Health Organization, only around 10% of the worldwide need for transplants is currently being met. The lung, taken from a Chinese Bama Xiang pig with six genetic modifications, was implanted into a 39-year-old male recipient. Researchers found that the organ functioned over a 216-hour period without triggering hyperacute rejection or infection.…

A new study suggests that following a Mediterranean-style diet could help lower the risk of dementia, even for people with genetic predispositions. The diet, rich in vegetables, fruits, nuts, whole grains, and low in red and processed meats, was linked to slower cognitive decline over a 30-year period. Genetic Risks and Diet’s Protective Role One of the strongest genetic risk factors for Alzheimer’s disease is the APOE4 gene variant. Carrying one copy triples the risk, while two copies increase it up to 12 times. However, researchers found that people with two copies of APOE4 benefited most from adhering to a…

Antarctica, long considered Earth’s last great wilderness, is increasingly under pressure from human activity. Visitor numbers have surged from fewer than 8,000 annually in the 1990s to more than 124,000 in 2023–24, with projections suggesting up to 450,000 by 2034. Researchers from Chile, Germany, and the Netherlands spent four years travelling 2,000 kilometres across the continent and found that areas with human activity now contain ten times higher concentrations of toxic metals such as nickel, copper, and lead than four decades ago. Tourism, along with expanding research bases, not only emits greenhouse gases but also introduces pollutants that accelerate snow…

Scientists have confirmed that extreme heat influences how people feel and behave. By analysing over a billion social media posts, they observed emotional patterns tied directly to rising temperatures. Once the heat crossed 35°C, negativity increased, with stronger effects in poorer regions than in wealthier ones. The research team, including MIT experts, assigned sentiment scores to online posts from 157 countries. They compared each score with local temperature data. Findings showed that low-income countries experienced far greater mood declines than high-income societies, illustrating unequal burdens of climate change. Behaviour in Hot Conditions Research over decades links heat to irritability and…

Asia stands at the forefront of cryptocurrency expansion, while the United States has recently accelerated under Trump’s new term. Europe, however, has chosen to build tight regulations instead of chasing faster growth. Bitcoin, once nearly worthless in 2009, now approaches $120,000, showing how far digital assets have entered financial mainstreams. What began as freedom from government systems is now subject to strict global oversight. The European Union introduced MiCA, a framework requiring customer asset separation, frequent audits, costly registrations, and mandatory transfer verification. Proponents claim these rules add confidence and safety. Critics argue they weigh heavily on companies, restrict innovation,…

Duolingo came under fire after a German lesson labelled J.K. Rowling mean. The company apologised and quickly removed the example. The task asked if learners enjoyed Harry Potter books. The suggested answer criticised Rowling instead of remaining neutral. A Duolingo spokesperson said the phrasing was inappropriate and confirmed the platform would keep its focus strictly on language learning. Rowling has long faced controversy for her remarks on trans rights, sparking strong reactions from activists, readers, and former cast members. Daniel Radcliffe expressed sadness about Rowling’s words and reaffirmed his dedication to defending LGBTQ rights. Ongoing Disputes and Literary Controversy Some…

Arctic sea ice has shown little overall decline since 2005, a development that has surprised scientists tracking global warming. They had expected continuous loss, yet shifting ocean patterns seem to have temporarily slowed the rate of ice retreat. Researchers stress this pause is short-lived and forecast that melting could soon accelerate, possibly doubling the long-term decline rate. Long-Term Shrinkage Despite the current slowdown, September ice cover has fallen by about half since 1979, when satellites began monitoring the Arctic. Experts highlight that the region is not recovering. Ice-free summers later this century remain highly likely, with major consequences ahead. The…

Experts warn that falling sperm counts worldwide directly connect to chemicals in plastics. Studies reveal nearly 60% reduction since the 1970s, with decline accelerating to over 2% yearly since 2000. Dr. Shanna Swan explains phthalates and bisphenols disrupt hormones, harming fetal boys and causing reduced fertility later. This crisis parallels booming plastic production, while regulation faces strong resistance. Geneva treaty talks collapsed when oil and gas nations blocked limits on harmful additives. Experts call for stronger chemical regulation, safer materials, and international cooperation to protect future fertility. Individuals may lower exposure using glass or steel, but only systemic action will…

Chocolate can take on many flavors – from fruity and floral to rich and bitter. Now, scientists have made a breakthrough in understanding the fermentation of cocoa beans. An international team led by Prof. David Salt from the University of Nottingham studied beans from three regions in Colombia and showed how specific microbes during fermentation strongly influence the taste of the final product. Nine key microbes identified While beans from Santander and Huila developed fruity and floral notes during fermentation, beans from Antioquia lacked these flavors due to the activity of different microbes. Using genetic analysis, the researchers identified nine…
