The Science Summit opens in Nairobi today with a serious ambition: to place African scientific leadership at the heart of the global agenda. Africa has never lacked questions. It has lacked sustained control over which questions receive money. UNESCO’s latest data puts research and development spending in Sub-Saharan Africa at 0.38 percent of GDP. The global figure is 1.92 percent. That gap is not merely a budget problem. It is a power arrangement. The person funding a question often influences which problem becomes scientifically visible. When the topic, method, timetable and expected result arrive inside the grant call, the local researcher can become a field assistant in his own continent. We export samples and import conclusions. A microscope does not become African because it cleared customs. This is not an argument against international collaboration. Science grows by crossing borders. Isolation would be expensive foolishness wearing a sovereignty badge. But collabora...

On September 28, 1928, Alexander Fleming noticed that mould had cleared bacteria from part of a culture plate. Humanity had found penicillin. Other scientists later turned that observation into medicine. We then behaved as though the miracle came with unlimited refills. Antibiotics changed the meaning of an infected wound. They made surgery safer, protected vulnerable patients and rescued ordinary people from bacteria that once turned small injuries into funerals. Then convenience began eating the gift. We take antibiotics for illnesses they cannot treat. We change doses or stop treatment without medical advice. In places where diagnosis is scarce, guessing often arrives before testing. Hospitals, farms, pharmacies, prescribers, manufacturers and patients all add pressure to the same invisible classroom. The pupils are bacteria. Resistance is not bacteria becoming wicked. It is evolution doing its work. An antibiotic kills susceptible bacteria. The survivors carry useful defences, re...

We have become very skilled at giving destruction professional names. A forest becomes timber inventory. A river becomes a drainage channel. Poison becomes an externality. Once a wound enters a spreadsheet, it begins to look productive. The 2026 Planetary Health Check has interrupted the euphemism. More than 60 scientists report that seven of Earth’s nine planetary boundaries have been breached. All seven are now at their highest recorded levels of transgression. Ocean acidification became the latest boundary to cross the safe limit in 2025. These boundaries are not imaginary lines painted around the planet. They describe interconnected systems—climate, freshwater, land, biodiversity, nutrient cycles, pollution and ocean chemistry—that help keep Earth stable enough for civilisation. We are dismantling the machinery while congratulating ourselves on factory output. The report speaks the language of science: resilience, thresholds, carbon sinks and tipping points. Beneath that l...

Scientists love the sentence: “It works.” The more important sentence is: “Someone else made it work.” A prototype can perform beautifully on its creator’s computer and still be unusable everywhere else. Perhaps it depends on an undocumented library, a particular driver, a forgotten environment variable and one sacred folder that must never be renamed. At that point, the invention is not entirely a tool. Part of it is folklore. I encountered this while building the Virtual BioSSD. Making the system run was one achievement. Making it possible for another researcher to install, test and reproduce without reenacting every setup struggle became a different engineering problem. The second problem is less glamorous. It may also determine whether the first achievement matters. The US National Academies distinguishes reproducibility from replicability. Reproducibility asks whether another researcher can obtain consistent results using the same data, code and methods. Replicability asks whet...

  Within the last three years,Humans have been bombarded with inventions from the scientific world,technological feats considered impossible in the last few hundred years. Now what inventions are literally changing  humans as soon as the hit the world shelf ? Introducing mehkury Top 10... 1. NASA Mars Insight A Craft That Will Probe Beyond the Surface of Mars Built by NASA,Its expected to launch in May of 2018.Its purpose is to hammer a probe more than 16 ft. into the Martian surface to study the planet’s thermal history—in effect, taking its geological temperature. Meanwhile, the seismometers will study Mars’ composition, an X-ray radio link will analyze wobble (the way Mars spins on its axis and is gravitationally tugged by other bodies in the solar system), and cameras will send panoramic and 3-D pictures back to earth. Its usefulness need not to be overstated as it's obvious that if the perception and the knowledge of humans about Ma...
