UP chemical pathology scientists develop ground-breaking nanobodies for COVID-19 detection and therapy
Researchers at the University of Pretoria (UP) are producing unique nanobodies that could be of ground-breaking use in rapid tests and as a therapy for COVID-19. In tests conducted in collaboration with the National Institute for Communicable Diseases (NICD), the nanobodies have been shown to neutralise SARS-CoV-2 in cells.
Invasive mosquito species could bring more malaria to Africa’s urban areas
A species of mosquito that can carry malaria – known as Anopheles stephensi – has invaded eastern Africa and is quickly moving across the region. Moina Spooner, from The Conversation Africa, asked Jeremy Herren and Clifford Mutero to provide insights into why this invasion is happening and what can be done to protect people from it.

Can wildlife biosurveillance prevent future pandemics?
“One health” refers to a transdisciplinary approach that focuses on the convergence of humans, animals and their various environments. The University of Pretoria (UP) is strategically well positioned to lead this research field because it has several faculties which, combined, have the necessary expertise and infrastructure to address the transdisciplinary research aspects of this complex field.

Breast Cancer Awareness Month: Prevention is in the genes
Globally, 14 million people are diagnosed with cancer each year, and about nine million lose their lives to the disease annually. But next-generation DNA technologies and sequencing are heralding a change to the outlook of the disease, and the rapid development and roll-out of DNA tests could save lives.
Fast facts about breast cancer
October is Breast Cancer Awareness Month, an annual campaign by private and public healthcare organisations to increase awareness of the disease on a national scale. In the infographic below, UP researcher Professor Annie Joubert guides us through some facts on breast cancer and what you need to know about the disease.
UP Whale Unit to gather data on dwindling southern right whale populations during 41st aerial survey
The Whale Unit at the University of Pretoria’s Mammal Research Institute (MRI) will be conducting this year’s aerial survey of southern right whales from 28 September to mid-October. This is the 41st annual southern right whale photo-identification aerial survey, making it one of the longest-running datasets on any marine mammal worldwide.
UP Zoology prof part of study that finds hummingbirds drop body temperature to near freezing point to survive cold nights
A University of Pretoria professor of zoology was part of a team that recently published a study that reveals that tiny hummingbirds living in the Andes Mountains in Peru drop their body temperature from 40°C to 3.3°C, near freezing point, to survive bitterly cold nights. “It is the lowest body temperature reported so far in any bird or non-hibernating mammal,” says UP’s Professor Andrew McKechnie.

New study finds SA’s springhare is a better hopper than Australia’s kangaroos
While kangaroos are distinguished for their well-developed hindlimbs which they use to hop across the Australian outback, it seems South Africa has its own unusual hopper – the springhare. A new study published in the Journal of Anatomy suggests that “the diminutive springhare is a bit better at hopping than its more famous Australian counterpart, at least when it comes to muscle-tendon design, and implications for fast and accelerative hopping”.
Video: Pretoria’s air is two times more polluted than the World Health Organisation allows.
Watch this short video which takes us through how air pollution is linked with human ill health, such as respiratory disease, and the links which UP researchers, Dr Bukola Olutola and Prof Janine Wichmann, have found between air pollution and respiratory disease on cold and warm days in a study carried out in Secunda.

Air pollution, temperature and respiratory disease: a South African study
Global warming and air pollution have something in common: their effects on human health. Air pollution is a well-known cause of breathing problems. Hot weather can also bring on these symptoms.
Video: How can we help the trees? International Year of Plant Health Part 5
Video: The polyphagous shot hole borer (PSHB) is a tiny, invasive black beetle from Asia that has recently been discovered in South Africa. Although only 2 mm in length, this tiny beetle has detrimental consequences for South African trees, as it carries a destructive fungus, Fusarium euwallaceae, from tree to tree.
