Medical Xpress / Reducing animal suffering in cancer research with fetal bovine serum-free cell culture models
For decades, human cancer cell lines have been indispensable models for cancer research, already replacing a significant number of animal experiments. However, the use of fetal bovine serum (FBS) in their cultivation is easily ...
Phys.org / Seismic attenuation techniques reveal what lies beneath Taiwan
As seismic waves travel through Earth, they gradually lose energy, a process called attenuation. That energy loss doesn't happen uniformly—some features in the crust sap far more energy from seismic waves than others. Researchers ...
Phys.org / Earth's first continents may trace back to subduction 3.5 billion years ago
An international team of researchers' analysis of minerals from the Pilbara region of Western Australia has given new insight into how ancient continents on Earth formed as far back as 3.5 billion years ago. Professor Tony ...
Phys.org / Wildfire smoke's hidden ozone threat may be adding thousands of US deaths each year
A study that assesses the effects of wildfires over two decades shows that wildfire smoke significantly raises ground-level ozone and contributes to excess deaths from wildfire smoke in the United States each year. The research, ...
Medical Xpress / Simple home test predicts mobility decline in older adults
Predicting whether a healthy 45-year-old will struggle to climb stairs or walk a decade later has long been a challenge for geriatric medicine. Now, a study published in JMIR Aging, reveals that early mobility decline can ...
Medical Xpress / Novel molecular marker may improve prostate cancer treatment
Most prostate cancers rely on male sex hormones, known as androgens, to grow. As a result, standard treatment focuses on lowering androgen levels or blocking their activity, but many tumors eventually become resistant and ...
Medical Xpress / Scientists discover hidden switch in immune cells that helps the body kill deadly fungus
Scientists at the University of East Anglia (UK) have contributed to discovering a "control switch" inside our immune cells that helps the body destroy dangerous fungal infections. Researchers found that a protein called ...
Phys.org / The birds and the babies: Humans and zebra finches have a similar technique for learning to speak
We are all born completely helpless, with little of the knowledge and skills we will need to survive as adults. Even our ability to communicate is almost entirely learned from our parents or caregivers.
Medical Xpress / AI models comb patient data to predict cardiac arrest risk
Researchers have developed artificial intelligence (AI) models that can scrutinize electronic health records (EHR) and electrocardiograms to identify individuals in the general population at elevated risk for sudden cardiac ...
Phys.org / Many of the Caribbean's most important reefs are going unprotected
Living by the sea in the tropics means being exposed to some of nature's most powerful forces. Hurricanes can bring storm surges, flooding and destructive waves that threaten homes, infrastructure and livelihoods.
Phys.org / The first direct observation of laser-created isolated hopfions
Over the past few decades, some physicists worldwide have been investigating unusual particle-like magnetic structures known as topological solitons. These structures could potentially be leveraged to develop new cutting-edge ...
Tech Xplore / Google disrupts hackers using AI to exploit an unknown weakness in a company's digital defense
Google said Monday that it had disrupted a criminal group's attempt to use artificial intelligence to exploit another company's previously unknown digital vulnerability, adding to heightened worries across government and ...
