Scientists discovered that the protein RPA plays a critical and previously unconfirmed role in stimulating telomerase to maintain long, healthy telomeres. When RPA malfunctions, telomeres can shorten dangerously, leading to serious diseases.
In a glimpse of the early universe, astronomers have observed a galaxy as it appeared just 800 million years after the Big Bang—a cosmic Jekyll and Hyde that looks like any other galaxy when viewed in visible and even ultraviolet light but transforms into a cosmic beast when
Financial crises may be made worse by current mortgage and housing tax systems according to new research from the University of Surrey. The study argues that the country should consider taxing housing purchases during strong economic periods but providing temporary subsidies on
People who lean politically to the right are more likely to fall for conspiracy theories than those on the left—but not for other types of false or misleading information. And regardless of ideology, we tend to accept political claims that align with our own beliefs. This is
New research led by the University of St Andrews has created the most comprehensive maps to date of the distribution of gray and harbor seals in Northwest Europe, encompassing the majority of seal populations on the continental shelf.
Scientists tracking young Arizona Bald Eagles found that many migrate north during summer and fall, bucking the traditional southbound pattern of most birds. Their routes rely heavily on historic stopover lakes and rivers, and often extend deep into Canada. As the eagles
A new economic modeling tool is helping Maine kelp farmers identify cost-saving strategies with remarkable precision. By analyzing farm design, weather, vessel types, and processing methods, it highlights how decisions ripple through overall profitability. When tested, the tool

On a typical school day in Australia this year, about 11% of students were absent. In 2014, the figure was 7%.
Sea urchins are ecosystem engineers, the marine equivalent of mega-herbivores on land. By grazing and shredding seaweed and seagrass, they control algal growth and promote the survival of slow-growing organisms like corals and some calcifying algae. They are likewise prey for a
Scientists discovered that certain cancer cells use a low-level activation of a DNA-dismantling enzyme—normally seen in cell death—to survive treatment. Instead of dying, these “persister cells” leverage this sublethal signal to regrow. Because the mechanism is non-genetic, it
