Warning signs over effectiveness of HIV ‘wonder drug’ in sub-Saharan Africa — ScienceDaily

Dolutegravir, the current first-line treatment for HIV, may not be as effective as hoped in sub-Saharan Africa, suggests new research published on World AIDS Day. The study finds that this so-called ‘wonder drug’ may be less effective in patients resistant to older drugs.

As HIV copies itself and replicates, it can develop errors, or ‘mutations’, in its genetic code (its RNA). While a drug may initially be able to supress or even kill the virus, certain mutations can allow the virus to develop resistance to its effects. If a mutated strain begins to spread within a population, it can mean once-effective drugs are no longer able to treat people.

HIV treatment usually consists of a cocktail of drugs that includes a type of drug known as a non-nucleoside reverse-transcriptase inhibitor (NNRTI). However, in recent years, HIV has begun to develop resistance to NNRTIs. Between 10% and 15% of patients in

On World AIDS Day, South Africa finds hope in new treatment

Health officials are hoping that new, long-acting drugs to help prevent HIV infection will be a turning point for the fight against a global health threat that’s been eclipsed by the coronavirus pandemic

South African President Cyril Ramaphosa highlighted the new drug in a weekly newsletter, saying the long-term acting and injectable HIV drug has “the potential to significantly strengthen our response to the epidemic.”

The region is especially hard-hit. South Africa has the biggest epidemic in the world with 7.7 million people living with HIV, according to UNAIDS.

Technology solutions thinking for Africa

By Opinion Time of article published2h ago

Share this article:

Some years ago I was talking to some newspaper editor and I said that we need to develop African solutions for Africa. He rolled his eyes and said; “Oh no, not that story again.”

I instantly realised that he thought that I meant: lower the standards. That was not at all what I meant. If anything I meant: increase the standards. I forget now which newspaper it was, and which editor, but I realised that the perception which he had about the phrase was rather universal.

So let me know explain what I meant. This is particularly important in considerations about technology development, and the implementation of technology–based systems, which means essentially everything. Now for a few surprising thoughts… The size of Africa is misrepresented on the standard map projection, is it far bigger than it

Middle East & Africa Gas Turbine Market Forecast to 2027 – COVID-19 Impact and Regional Analysis By Technology, Capacity, and Application

New York, Nov. 26, 2020 (GLOBE NEWSWIRE) — Reportlinker.com announces the release of the report “Middle East & Africa Gas Turbine Market Forecast to 2027 – COVID-19 Impact and Regional Analysis By Technology, Capacity, and Application” – https://www.reportlinker.com/p05989553/?utm_source=GNW

Gas-fired turbines are faster, more efficient, and less polluting than coal-fired and nuclear power plants.High power-to-weight ratio and low operations pressure are among the various advantages associated with these turbines.

Besides, the gas turbines are durable and efficient, and cheaper to install.They exhibit less downtime and functional failure compared to nuclear and coal-driven turbines.

Increasing demand for natural gas-fired power plants, rising concerns regarding greenhouse gas emissions, and stringent government norms have stimulated the demand for gas turbines.Moreover, governments of the countries in this region offer incentives to companies using natural gas-based turbines for power generation.

In several countries, nuclear power stations have been closed due to political pressure which has led

Middle East & Africa Geosteering Technology Market Forecast to 2027 – COVID-19 Impact and Regional Analysis By Product and Application

New York, Nov. 26, 2020 (GLOBE NEWSWIRE) — Reportlinker.com announces the release of the report “Middle East & Africa Geosteering Technology Market Forecast to 2027 – COVID-19 Impact and Regional Analysis By Product and Application” – https://www.reportlinker.com/p05989554/?utm_source=GNW
Geosteering technologies are widely applied for well-placement operations in the oil & gas industry across the MEA.Geosteering gives real-time information in the form of imaging surveys.

This technology provides 2D and 3D terrain projections around the oil reservoir by continuously adjusting the drill head positioned above an oil well.The drill operating team also uses electronic logs and drill cutting operations to identify the paleontological properties and surfaces to be drilled in the field.

For the above processes, geosteering uses different methods, such as logging while drilling (LWD), measurement-while-drilling (MWD), and drive systems.Therefore, increase in demand for accurate real-time information to achieve highest production is expected to escalate the need for geosteering technology due

Agri-tech continues to transform the future of food security in Africa

70% of Africans rely solely on agricultural income. But with a growing global population and mounting pressure to double outputs by the year 2050, farmers continue with the struggle of keeping up with the demand. Faced with challenges such as outdated methods and equipment, earth cracked dry from changes in climate and locked in an ongoing battle with destructive plagues, farmers are facing odds stacked against them.

But technology is ushering change. Powering a new era of farming, agritech solutions from all over the world are seeing unprecedented investment – with start-ups growing 110% in the past two years, and showing no sign of slowing down.

Microsoft has been partnering with public and private organisations to develop systems that support better policy making around agriculture. One example of this is the organistions work with the Ministry of Agriculture, Livestock, Fisheries and Cooperatives (MALFC) in Kenya

Duckbill Dino Odyssey Ended in Africa

In North America, fossils of duckbill dinosaur are abundant. So abundant that paleontologists sometimes ignore them in search of more exciting species, like T. Rex or Triceratops.

“They were so common we often wouldn’t collect them and just left them out in the field.”

University of Bath evolutionary biologist Nick Longrich.

But duckbills had never been found in Africa. So, Longrich did a double take when he was visiting the Natural History Museum of Marrakesh in Morocco and came across the 66-million-year-old jawbone of a previously undocumented duckbill species.

“I instantly knew what it was, and I just couldn’t figure out what it was doing there.”

Its presence in North Africa was problematic because during the Late Cretaceous period the planet was warmer, which means sea levels were higher.

“Africa was isolated from all the other continents by water, and there didn’t seem to be any way that they

Dimming Sun’s rays could ease climate impacts in Africa

The 2017 'Day Zero' drought in South Africa left reservoirs barren
The 2017 ‘Day Zero’ drought in South Africa left reservoirs barren

Dialling down the Sun’s heat a notch by injecting billions of shiny sulphur dioxide particles into the stratosphere could curtail devastating drought across parts of Africa, new peer-reviewed research has reported.


This form of solar radiation management would slash the risk of another “Day Zero” drought in Cape Town, South Africa—a city of 3.7 million which ran out of water in 2017—by as much as 90 percent, according to a study published last week in Environmental Research Letters.

Global warming to date—just over one degree Celsius since the mid-19th century—enhances the likelihood of such droughts by a factor of three, earlier research has shown.

Allowing temperatures to increase another degree to 2C above preindustrial levels would triple the risk again.

The 2015 Paris climate treaty, signed by virtually all the world’s nations, calls for capping global warming at
