Is mathematics a discovery or an invention? The answers to this question are an important part of the philosophy of mathematics. To answer it, philosophers would like to know whether mathematics is a natural part of this world that existed before humans discovered and comprehended it or if mathematics was invented by humans. In this…
Spike protein when injected into the skulls of mice caused brain inflammation Long COVID is a condition marked by multiple persistent symptoms that sometimes occur even after mild infections. Among these, memory loss, brain fog and sleep disturbances indicate brain involvement. MRI scans done before and after COVID-19 show shrinkage in certain brain regions, pointing…

Hummingbird bills — their long, thin beaks — look a little like drinking straws. The frenetic speed at which they get nectar out of flowers and backyard feeders may give the impression that the bills act as straws, too. But new research shows just how little water, or nectar, that comparison holds. Far from being…

Intermittent fasting has proven benefits for metabolic health, but a new study shows that it could slow hair growth — at least in mice. Researchers report in the Cell that mice subjected to intermittent fasting regimes show improved metabolic health but slower hair regeneration compared to mice with 24/7 access to food. A similar process might occur…

Do you know what jet streams are? No no, these aren’t the streams of jet that you can see when a flight cruises at speed. Don’t confuse it with an ocean current of drifting seawater either. A jet stream is a fast-moving, narrow current of air meandering in the atmosphere. It isn’t unique to Earth,…
Two vaccines against malaria have been rolled out in some countries in Africa. Besides vaccines, scientists have been using genetically altered mosquitoes to stop the spread of malaria. One is the release of radiation-sterilised male mosquitoes to prevent eggs from hatching. Another is engineering mosquitoes that slow the growth of malaria-causing parasites in the gut thereby…
