Small settlements and the scourge of slavery left gaps in Africa’s archaeological record. Yet sites and artifacts are revealing clues to the continent’s more recent history. An archaeologist explains the findings and threats to this heritage.
Advanced light microscopy techniques have come into their own — and are giving scientists a new understanding of human biology and what goes wrong in disease
Infusion of the tiny, sausage-shaped structures helps to rejuvenate tissues deprived of blood. Researchers hope the technique can treat a variety of damaged organs.
Carshares, bikeshares and the like are a positive for the environment, though access to them isn’t equal. What can be done to give everyone more transportation options?
Nigeria is pioneering the development of small, off-grid solar panel installations to bring reliable electricity to remote communities — setting a model for other African countries
Can genetically modified animals help ease the shortage of organs? After years of research into xenotransplantation, the field is at a turning point — yet risks and ethical issues remain.
Misinformation, market volatility and more: Faced with the need to mitigate risks that artificial intelligence presents, countries and regions are charting different paths
The revolutionary James Webb Space Telescope and next-gen radio telescopes are probing what’s known as the epoch of reionization. It holds clues to the first stars and galaxies, and perhaps the nature of dark matter.
When the Sun doesn’t shine and the wind doesn’t blow, humanity still needs power. Researchers are designing new technologies, from reinvented batteries to compressed air and spinning wheels, to keep energy in reserve for the lean times.
This record-setting year for heat saw stunning auroras, a map of a brain, a Dengue epidemic, the first look at rocks from the far side of the Moon, an AI energy scramble and more
Getting our homes and workplaces to be energy efficient has major benefits — but not when it is done one window at a time. Here’s why deep retrofits and biomaterials are key to more sustainable living.
Miles away from the ocean, projects are afoot to clean up salty groundwater and use it to grow crops. Some say it’s a costly pipe dream, others say it’s part of the future.
Hint: It involves finding just the right proteins. With new ingredients and processes, the next generation of substitutes will be not just more egg-like, but potentially more nutritious.
In the international competition, people with physical disabilities put state-of-the-art devices to the test as they race to complete the tasks of everyday life
Some people of West African descent face a higher risk of renal failure. New drugs based on gene research may help right the ship — if they can reach everyone who needs them.
