**Fur Seals’ Hearts Suddenly Spike Hours After Returning to Land** By Frontiers - Published on 15 May 2026 Fur seals may look relaxed on shore, but their hearts reveal a hidden battle still underway after deep dives. Diving places enormous physical stress on marine mammals. During long and deep dives, animals can switch to ‘anaerobic’ (oxygen-less) metabolism in parts of the body outside the heart and brain, which leads to a buildup of [...] Read more: https://scitechdaily.com/fur-seals-hearts-suddenly-spike-hours-after-returning-to-land/ #fourseal #marinebiology #biophysiology #oceanography #cardiovascularscience #Biology #Frontiers #MarineBiology

**Scientists Say Cognitive Decline Isn’t Inevitable — Your Brain Can Improve at Any Age** By Center for BrainHealth - Published on 15 May 2026 A long-term study found that brain health can improve throughout life with consistent daily habits, cognitive training, and personalized support, regardless of age. What if the brain doesn’t have to follow the familiar path of gradual decline with age? A major new study published in Scientific Reports is challenging long-held assumptions about aging, revealing that [...] Read more: https://scitechdaily.com/scientists-say-cognitive-decline-isnt-inevitable-your-brain-can-improve-at-any-age/ #CognitiveHealth #BrainScience #Neuroscience #LifelongLearning #BrainTraining #Biology #Aging #Brain

**This Weird Sea Creature May Have Rewritten Life’s Genetic Rulebook** By Center for Genomic Regulation - Published on 15 May 2026 Long-distance gene control first emerged around 650 to 700 million years ago, significantly earlier than scientists had previously believed. Life depends on timing. Every cell must turn genes on and off at just the right moment. Even the simplest forms of life have mastered this, usually with switches located right next to the genes they [...] Read more: https://scitechdaily.com/this-weird-sea-creature-may-have-rewritten-lifes-genetic-rulebook/ #Genetics #GeneControl #Evolution #MarineBiology #MarineGenomics #Biology #CellBiology #DNA

**The Hidden Types of Dementia Most People Have Never Heard Of** By Clarissa Giebel, University of Liverpool - Published on 15 May 2026 Dementia is more than memory loss, and rare types can affect vision, movement, and behavior. Recognizing these symptoms early can improve diagnosis and support. When most people hear the word “dementia,” they think of memory loss and forgetfulness. But dementia can affect far more than memory, causing changes in speech, behavior, sleep, movement, and other [...] Read more: https://scitechdaily.com/the-hidden-types-of-dementia-most-people-have-never-heard-of/ #dementia #neuroscience #healthtech #biomedicine #brainhealth #Health #AlzheimersDisease #Brain

**Scientists Discover Why Alcohol Prevents the Liver From Healing, Even After You Quit** By SciTechDaily.com - Published on 15 May 2026 Scientists have uncovered why severely damaged livers can continue failing even after a person stops drinking alcohol. The human liver is famous for its ability to regenerate. Ancient myths even referenced its seemingly endless capacity to heal. But in people with severe alcohol-related liver disease, that recovery system can suddenly fail, leaving the organ unable [...] Read more: https://scitechdaily.com/scientists-discover-why-alcohol-prevents-the-liver-from-healing-even-after-you-quit/ #LiverHealth #AlcoholResearch #Hepatology #RegenerativeMedicine #CellRegeneration #Science #Alcohol #Inflammation

**Scientists Solve a 60-Year-Old Fat Cell Mystery — and It Changes What We Know About Obesity** By SciTechDaily.com - Published on 15 May 2026 A decades-old assumption about how the body handles fat may have been incomplete. For 60 years, scientists believed they understood exactly how a protein called HSL worked. Since the 1960s, hormone-sensitive lipase has been recognized as one of the body’s main fat-burning enzymes, helping release stored fat when energy is needed. But there was one [...] Read more: https://scitechdaily.com/scientists-solve-a-60-year-old-fat-cell-mystery-and-it-changes-what-we-know-about-obesity/ #ObesityResearch #FatCellScience #HSL #Metabolism #CellBiology #Health #Fat #Metabolism

**A Crucial Atlantic Current Is Weakening and Weather Could Change Worldwide** By University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science - Published on 15 May 2026 A giant Atlantic Ocean current that helps regulate Earth’s climate is slowing down, and scientists say the impacts could be global. A massive Atlantic Ocean circulation system that plays a central role in regulating Earth’s climate has been weakening for nearly 20 years, according to a new study. Scientists say the slowdown spans a large [...] Read more: https://scitechdaily.com/a-crucial-atlantic-current-is-weakening-and-weather-could-change-worldwide/ #ClimateChange #AtlanticCurrent #AMOC #Oceanography #ClimateScience #Earth #ClimateScience #Oceanography

**Scientists Stunned As Volcano Removes Methane From the Air** By University of Copenhagen - Published on 15 May 2026 A giant volcano may have accidentally uncovered a powerful new way to destroy methane in Earth’s atmosphere. In January 2022, the underwater volcano Hunga Tonga–Hunga Ha’apai in the South Pacific unleashed one of the most powerful eruptions ever recorded in modern times. But scientists have now discovered that the eruption did something completely unexpected: it [...] Read more: https://scitechdaily.com/scientists-stunned-as-volcano-removes-methane-from-the-air/ #Volcano #Methane #ClimateScience #AtmosphericChemistry #CarbonCycle #Earth #AtmosphericChemistry #AtmosphericScience

**Scientists Discover Signs Africa May Be Splitting Apart Beneath Zambia** By Frontiers - Published on 15 May 2026 Unusual helium signatures detected in Zambian hot springs may signal that a hidden tectonic rift is actively developing beneath southwestern Africa. Deep beneath Zambia, scientists may have uncovered signs that Africa is slowly tearing apart. Clues rising from bubbling geothermal springs suggest that molten material from Earth’s mantle is pushing upward through a hidden fracture [...] Read more: https://scitechdaily.com/scientists-discover-signs-africa-may-be-splitting-apart-beneath-zambia/ #Geology #Geophysics #PlateTectonics #TectonicRift #EarthScience #Earth #EarthScience #Frontiers

**New Stroke Study Challenges Decades-Old Medical Beliefs** By University of Edinburgh - Published on 15 May 2026 Lacunar stroke may arise from damage in the brain’s small blood vessels rather than fatty plaque in larger arteries, pointing researchers toward new treatment strategies. Scientists have found new evidence that calls into question a long-standing explanation for a common form of stroke, and it may help clarify why standard prevention treatments often fall short.
