Despite the success of HIV drugs and PrEP, precarious health-care systems and high drug costs mean we can’t rely on them to bring an end to the ongoing global HIV pandemic.Over the past three decades, there have been amazing advances in treating and preventing HIV. It’s now a manageable infection. A person with HIV who takes HIV medicine consistently, before their immune system declines, can expect to live almost as long as someone without HIV. The same drugs prevent transmission of the virus to sexual partners. There is still no effective HIV vaccine. But there are highly effective drugs to…

Sleeping too long (meaning more than the recommended amount for your age) is associated with health problems. But what about sleeping “too much”?

It can be hard not to feel confused and worried. But how much sleep do we need? And what can sleeping a lot really tell us about our health? Let’s unpack the evidence. Sleep is essential for our health Along with nutrition and physical activity, sleep is an essential pillar of…
Here are some other things you might not know about blood. 1. Blood is both liquid and solid Blood is a connective tissue in the body. It has a multi-cellular component (made of red blood cells, white blood cells and platelets) and a liquid extracellular matrix. Unlike the other connective tissues in the body, blood is a liquid. The extracellular matrix, plasma, is liquid and suspends the cells in blood. But when tissues are damaged, by a cut for example, blood becomes a solid like other connective tissues. This is known as clotting. Clotting is activated by exposure to anything…
Big tech sharing economy platforms like Airbnb and Uber are marketed as trustworthy, but a new book by a South African media scholar argues that they are highly vulnerable to scammers who spread delusive speech (a form of disinformation, designed to deceive by criminal intent). Julie Reid draws from first-hand accounts and over 600 cases from around the world of victims lured into scams or physical danger by fake Airbnb reviews and listings, providing a detailed case study. We asked her five questions about her book. How do the scams work? Airbnb is the world’s largest accommodation-sharing platform. It connects property owners who want…
Kibera slum in Nairobi. [File, Standard] In Kenya’s capital city, Nairobi, it is estimated that over 70 per cent of the population live in informal settlements. Many of these have a history rooted in colonial policies whereby the “African native” was a temporary resident of the city. Africans could only live in the city as registered labourers. As these informal settlements grew over the years, their names – and the names of places within them – have grown to encapsulate their history. Africans were forced to live in dormitory-like working quarters. In spite of these restrictions some still found their…
Joseph Kony addresses journalists in southern Sudan in November 2006. [AFP] Eleven years ago, a documentary catapulted the name Joseph Kony onto the global stage. The controversial film Kony 2012 told the story of a Ugandan warlord whose forces are believed by the United Nations to be responsible for the deaths of more than 100,000 people, the abduction of at least 20,000 children and the displacement of more than two million people. Though most of the world hadn’t heard of Kony before then, Ugandans knew and feared him. The founder of the Lord’s Resistance Army unleashed a wave of violence…
NSE Market watch board during ringing of the bell ceremony at Nairobi Securities Exchange, on September 4, 2019. [File, Standard] Over the past two decades, African countries have increasingly turned to international capital markets to meet their development financing needs. Fo example, Kenya and Benin raised a combined $2.5 billion through bond issuances during the first half of 2025. Proceeds were used to repay maturing bonds. This means new bonds, with unfavourable terms, are being issued to pay previous lenders. Yet African bonds are substantially mispriced, resulting in excessively high yields that are not justified by fundamentals – based on economic, fiscal and institutional…
The recent killing in Kenya of Albert Ojwang in police detention highlights a string of systemic failures to hold the country’s security officers accountable for their actions. Despite public outrage and protests, Kenyan police officers continue to use inhumane, brutal and sometimes fatal methods with little consequence. Douglas Lucas Kivoi, who has studied policing and police reform in Kenya, unpacks the situation. Why is the Kenyan police service given to brutality? First, Kenya’s police institution was established as a colonial instrument of oppression. Police reforms since independence in 1963 have had little impact in changing this. Instead, successive governments have used the…
Easter Eggs In Basket On Grass With Sunny Sky Background. [Courtesy] A lot of Easter traditions – including hot cross buns and lamb on Sunday – stem from medieval Christian or even earlier pagan beliefs. The chocolate Easter egg, however, is a more modern twist on tradition. Chicken eggs have been eaten at Easter for centuries. Eggs have long symbolised rebirth and renewal, making them perfect to commemorate the story of Jesus’ resurrection as well as the arrival of spring. Although nowadays eggs can be eaten during the fasting period of Lent, in the middle ages they were prohibited along with meat…
