A new antiretroviral drug regimen has been given the go-ahead by the World Health Organisation. This follows the preliminary results from studies that include an ongoing trial in South Africa.
Rewilding and restoration of land often rely on the reintroduction of species. But what happens when what you want to reintroduce no longer exists? What if the animal in question is not only locally extinct, but gone for good?
Data are generated every time we make a purchase or receive other services such as health care. This has always been the case, but over the past 20 years, data collection has become increasingly automated, with data collected and stored in digital (rather than paper) formats.
I am a scientist who researches climate hazards. This week I have published research on the potential for a catastrophic cyclone-heatwave combo in the global south. Yet over the past few days I have been approached by various media outlets to talk not about that hazard, but about the unfolding UK heatwave and climate change. It is always satisfying to respond to public interest around weather extremes, but there is a danger that key messages about extreme heat globally are not receiving enough airtime.
Unlike the many species which stalk the shallow, coastal waters that fisheries exploit all year round, pelagic sharks roam the vast open oceans. These are the long-distance travellers of the submarine world and include the world’s largest fish, the whale shark, and also one of the fastest fish in the sea, the shortfin mako shark, capable of swimming at 40mph.
Visitors to East Africa are often amazed by massive herds of cattle with a gorgeous array of horn, hump and coat patterns. Pastoralism – a way of life centered around herding – is a central part of many Africans’ identity. It’s also a key economic strategy that is now threatened by climate change, rising demands for meat, urban sprawl and land conflicts.
Genetic testing used to be something that happened in a specialist clinic for those few families that had serious inherited conditions, like Huntington’s Disease or rare cancers.
Now, new genetic tests called “polygenic risk scores” have increased access to genetic risk information for a wide range of conditions. With a few clicks of a mouse and a few hundred dollars, anyone can access their or their genetic risk scores for diabetes, obesity, breast cancer, autism, and schizophrenia.
Antibiotic resistance is here to stay, but that doesn’t mean we can’t do anything to stop it.
A headline that always catches my attention is that antibiotic resistance is on the rise. Underlying these headlines is that the disease-causing bacteria that make us sick are becoming less responsive to treatment by our most common antibiotics.
In astronomy, we have a common saying: “good luck, and clear skies”. For an eclipse chaser like me, this is especially important. We have two minutes and no second chance – one small cloud can spoil everything.
Young people are now fully ensconced in the digital age as it whirls around and within them.
This is the epoch of the Anthropocene — the age of humans, wherein a technological worldview and human tools hold the central place in re-shaping the earth and its people. It’s also a time when 1.8 billion youth make up the largest generation of 10 to 24 year olds in human history with 50 per cent of the world’s population under 30 years of age.
