Phys.org / Ammonia as a clean fuel: 'Do not create a new nitrogen problem,' says researcher
Ammonia has been feeding the world for decades as a fertilizer and is now rapidly emerging as a carbon-free fuel for shipping and industry. But if we focus only on CO₂ emissions, we risk creating new nitrogen problems, warns ...
Medical Xpress / Scientists transform wool into bone repair material
Scientists have shown how wool could offer an effective and sustainable alternative to materials currently used to repair damaged bone. In the new study, keratin—a natural structural protein derived from wool—was shown to ...
Phys.org / Saturday Citations: Cruise ship pathogen spread in ancient Rome; Plus: Pomegranates, retinal implants
This week, researchers reported that malaria influenced population distribution in Africa thousands of years ago. Mathematicians at MIT report that classical physics formulations can explain quantum phenomena. And a study ...
Medical Xpress / Anemia in adults 60 and older linked to 66% higher dementia risk
A new study has found that the effects of anemia—a condition caused by a lack of hemoglobin needed to carry oxygen to organs and tissues—may stretch beyond fatigue, shortness of breath, and pale skin. They reach into the ...
Medical Xpress / Targeting lost pleasure lifts depression and anxiety more than standard therapy, new study finds
Most people know depression as a disorder of sadness. But for millions of patients, the most debilitating feature is something else entirely: the reduced ability or inability to feel positive emotions.
Science X / Kakapel rock art traces millennia of painters in Kenya
A recent study published in Azania: Archaeological Research in Africa presents the first millimeter-accurate recording of the paintings at Kakapel rock shelter in Kenya, linking the layers of rock art painted over thousands ...
Science X / From public kissing to talking during movies, a simple formula predicts moral norms across cultures
People living in different countries and societies worldwide can have very different views on what behaviors are acceptable. In the field of sociology, these population-level judgments are broadly referred to as moral and ...
Medical Xpress / Microplastics in human liver could be fueling global surge in disease
There is considerable evidence that microplastics and nanoplastics are present in the livers of humans, and wild animal populations on land and in the ocean. Now experts in environmental and human health are investigating ...
