Physicists from the University of the Witwatersrand (Wits) have developed an innovative computing system using laser beams and everyday display technology, marking a significant leap forward in the quest for more powerful quantum computing solutions.
In the largest systematic review of its kind, we reviewed 198 studies that assessed the impact of heat on maternal, fetal, and neonatal health, across 66 countries.
We found that for every 1°C increase in heat exposure, there was a 4% increase in odds of preterm birth across all the studies. During a heatwave, the odds of preterm birth increased by 26%. Similarly, we found marked increases in other adverse outcomes such as increased risk for gestational diabetes, stillbirths, congenital anomalies and obstetric complications with increasing exposure to heat. There is limited research on outcomes like antenatal bleeding and caesarian section risks that may be related to heat exposure and could contribute significantly to morbidity and mortality.
“Our research provides compelling evidence that heat exposure poses severe health risks for pregnant women and their babies, yet these risks are frequently underestimated”, said Prof. Matthew Chersich, executive director at Wits Planetary Health Research.
In a remarkable journey back to the Jurassic Era, scientists have used cutting-edge technology to uncover secrets about Orthosuchus stormbergi, a small, early ancestor of today’s crocodiles. Unlike its modern relatives, which are renowned for their massive size and aquatic prowess, this tiny croc offers unique insights into the evolution of its lineage. Standing out for its slow growth and diminutive adult size, Orthosuchus paints a fascinating picture of ancient ecosystems and crocodilian history.
Scientists from South Africa and Brazil have provided empirical evidence that pollen grains of rival plants may compete with one another for space on pollinators, thus influencing whose pollen is going to make it to the next flower – or not.
In an article published in The American Naturalist this week, they argue that because plants can manipulate where and how much pollen is placed on the bodies of pollinators, plants may have developed strategies that are similar to sperm manipulation in animals.
A 200 year old painting in a cave on the La Belle France farm in the Free State province of South Africa, may be the world's oldest known piece of paleo-art depicting an extinct mammal-like reptile called a dicynodont, predating the creature's official scientific discovery by at least a decade.
Professor Julien Benoit, a palaeontologist at the University of the Witwatersrand (Wits University), has reinterpreted this mysterious rock art, that has previously been misidentified as a walrus-like creature or even a surviving sabre-toothed cat. He identified the animal in the image as a Dicynodont, that lived between 265 and 200 million years ago.A new report ‘Eating Wild Animals: Rewards, Risks and Recommendations’ led by experts of the International Livestock Research Institute (ILRI) uncovers the perils and promise of wild meat hunting, consumption and trade in Africa and Southeast Asia.
It is the first evidenced-based synthesis to focus on "wild meat" nutrition and disease issues rather than wildlife conservation alone, integrating ecology and epidemiology sciences and concerns for both human well-being and animal welfare.
