New research published in communication medicine Our results suggest that experiencing suffering may predict worse well-being in various areas of life approximately one year later. These findings provide evidence that addressing everyday emotional and physical suffering is a critical step toward improving collective human flourishing on a global scale. Human life is full of various difficulties, inconveniences, and adversities. In some cases, these difficult events can lead to a state of suffering. Suffering is generally defined as an extremely painful personal experience that lasts for a significant period of time and involves the loss of something that a person perceives…

New research presented today at the International Society for Stem Cell Research (ISSCR) 2026 Annual Meeting highlights an important step toward developing stem cell-based treatments for chronic spinal cord injury (SCI), for which no effective restorative therapy currently exists. Hideyuki Okano, MD, Keio University, presented new preclinical efficacy data using clinical-grade gliogenic neural stem/progenitor cells (gNS/PC) for chronic incomplete SCI and new updated plans for an investigator-initiated clinical trial targeting patient recruitment in 2027. This discovery builds on the successful completion of the world’s first first-in-human clinical trial in patients with subacute SCI, which demonstrated a promising safety profile. …

Portable screen-printed carbon electrode (SPCE) biosensors provide a rapid and low-cost method to detect microcystin-lysine-arginine (MC-LR), a highly potent toxin produced by cyanobacteria during harmful algal blooms in freshwater. Because MC-LR can damage the liver even at low concentrations and is associated with an increased risk of liver and colon cancer, the World Health Organization has set a guideline value for MC-LR in drinking water at 1 microgram per liter. SPCE sensors work by measuring changes in electrochemical signals that reflect the concentration of toxins. However, the accuracy of these sensors is highly influenced by the water being tested. Factors…

Air pollution from cruise ships can harm the health of people living in port cities by increasing inflammation and increasing susceptibility to viruses such as the common cold and COVID-19. New research from the University of Southampton reveals environment international We studied the atmosphere in Southampton’s harbour. The air contained ultrafine particulate matter (PM), dust particles less than one-thousandth the width of a human hair, and was rich in trace elements from the combustion of transportation fuels. Clinical tests have shown that these particles increase inflammatory signals and weaken cells’ defenses against viral infections such as COVID-19 and the common…

An experimental study of individuals suffering from persistent depressive disorder found that treatment with the antidepressants duloxetine and desvenlafaxine normalized tissue microstructure in parts of the brain. Symptom severity mediated treatment effects on tissue microstructure, suggesting that abnormal tissue at the beginning of the study may be a compensatory response of the brain to symptoms of depression. The paper is NeuroImage: Clinical. Persistent depressive disorder, formerly known as dysthymia, is a chronic condition in adults in which low mood and related symptoms persist for at least two years. Symptoms include low energy, difficulty concentrating, feelings of hopelessness, low self-esteem, trouble…

Researchers at Tokyo Metropolitan University have developed a new way to control ink drying by adding ultrafine bubbles to ink droplets instead of chemical additives. The researchers found that by simply changing the number of air bubbles within each droplet, they could dramatically change the pattern that remains when the liquid evaporates. This approach may be particularly valuable for manufacturing small electronic devices where residual additives can interfere with the performance of printed materials. Inkjet printing is no longer just used for documents and images. This has become an essential manufacturing technique for advanced technologies such as microelectronics and MEMS…

Physicists from Finland’s Jyväskylä University and Aalto University have successfully created a two-dimensional topological crystalline insulator, marking the first experimental realization of a quantum material that scientists have predicted for more than a decade. Until now, attempts to manufacture them have been hampered by difficulties in developing suitable materials. This breakthrough was led by Associate Professor Kezilbiek Shawulienu in collaboration with Aalto University researchers including Professor Peter Liljeroth and Professor Jose Lado. The researchers created the material by growing atomically thin films of just two layers of tin telluride (SnTe) on a niobium diselenide (NbSe2) substrate. Atomicly thin crystal reveals…

A rare goose fossil discovered at the remains of an ancient lake in Central Otago is changing scientists’ understanding of how New Zealand’s unique bird species evolved. Researchers from the University of Otago’s Otakou Whakaifu Waka say the discovery adds to growing evidence that the origin of Aotearoa’s birds was far more dynamic than previously thought. Associate Professor Nick Lawrence, director of the Otago Institute of Paleogenetics, is a co-author of a new study investigating the relationship between fossils and their evolution. This study historical biologycarried out by an international team from the University of Otago, Te Papa Tongarewa Museum,…

When SpaceX’s Starship launched from the Texas coast in the summer of 2023, it marked a milestone that aerospace engineers have been talking about for decades, but few expected to witness so soon. The towering stainless steel rocket, taller than a 30-story building, ignited all 33 engines and rose into the sky. Although the mission did not unfold perfectly, it proved that the concept could be realized. Its importance became even clearer during Starship’s fifth integrated flight test, when a returning super heavy booster was successfully captured in midair by the launch tower’s giant mechanical arm. This demonstration signaled the…

The human body is often described as a marvel of “perfect design”: elegant, efficient, and finely tuned for purpose. But a closer look reveals a very different picture. Far from being perfect machines, their bodies appear to be a patchwork of compromises formed over millions of years of evolution. Evolution does not design structures from scratch. Rather, it changes something that already exists. As a result, many aspects of human anatomy have become “good enough” solutions, i.e. functional, but far from perfect. Some of the most well-known medical problems and diseases result directly from these genetic constraints.spineThe human spine illustrates…
