Phys.org / Fossil plankton shells reveal reduced nitrogen fixation in warmer oceans 3 million years ago
Nitrogen is a key nutrient because it fuels the growth of plankton, which forms the basis of the marine food web. Two opposing processes determine the global nitrogen cycle: nitrogen fixation and denitrification.
Medical Xpress / Screening method identifies leukemia drug candidates from more than 4 million compounds
A cancer cell behaves differently from a healthy cell, with unique features that enable rapid growth and bypass quality controls. Rice University's Natasha Kirienko is interested in finding these unique features and exploiting ...
Phys.org / Luminescence dating pushes age of South Dakota's Mammoth Site back by more than 100,000 years
Deep within an ancient sinkhole lie the remains of dozens of mammoths, prehistoric wanderers who waded into the warm springs to their deaths. These deaths had long been accepted as having occurred roughly 26,000 years ago, ...
Phys.org / Ubiquitin marks abnormal glycogen for destruction to protect the brain, study finds
Researchers at the University of Cambridge and the MRC Laboratory of Molecular Biology have discovered a previously unknown cellular defense system that protects the brain from abnormal glycogen accumulation, which is linked ...
Medical Xpress / Restored thyroid receptor makes aggressive tumors more vulnerable to CAR-T cell therapy
Mayo Clinic researchers have identified a strategy that could help chimeric antigen receptor-T cell therapy, or CAR-T cell therapy, overcome a major barrier to treating solid tumors: Cancer cells can change in ways that allow ...
Phys.org / A finely tuned mess—how disorder can make networks more stable
Perfection is overrated—at least when it comes to complex systems like the power grid, food webs and advanced materials. For decades, scientists generally assumed that networks function most reliably when their individual ...
Medical Xpress / Italy sees mosquitos spread the West Nile virus farther and longer as Europe warms
Italian health authorities see evidence that rising temperatures and longer warm seasons are helping mosquitoes spread West Nile virus across a wider area, during more months of the year.
Phys.org / Newfound fungal nutrient-sensing mechanism could advance biofuels and disease control
Scientists have taken a step toward a better understanding of how fungi sense and respond to nutrients in the environment, which is critical for engineering fungi for green technologies and combating fungal pathogens and ...
Medical Xpress / Augmented eye clinic shows why AI-native systems work where standalone algorithms don't
AI in eye care is set to take a new leap with an AI-native rather than assisted approach. Researchers have developed a new tool that moves beyond the conventional model of deploying AI as isolated, standalone tools for individual ...
Phys.org / Rethinking how we assess students could improve their well-being
When you were in school, what stressed you out the most? For many students, classroom assessments—graded tests, quizzes, group work, presentations, labs and the like—would be near the top of the list.
Phys.org / Portable metasurface biosensor turns molecular signals into images, bypassing spectrometers
What if signs of disease could be detected using nothing more than a tiny chip that fits in the palm of your hand and a camera, without ever visiting a hospital? A scene that once seemed possible only in science fiction has ...
Phys.org / New species of 240-million-year-old prehistoric animal could reshape dinosaur origins timeline
A new prehistoric animal species from Tanzania dating to around 240 million years ago, during the Triassic period, has been described by an international team of researchers. Led by the University of Bristol, the new species, ...
