The empty set may seem a bit feeble, but appearances deceive; it provides a vital building block for the whole of mathematics.
The “remarkable recent economic growth” in many African countries may be able to sustain science through domestic funding (rather than through external sources) — but a lack of scientists and research capacity is threatening to reel back that economic growth, a meeting has heard. The gross domestic product (GDP) of many African countries has been…
Astronomers have discovered a new kind of supernova, a star explosion so weak that scientists dubbed it a miniature stellar blast. Supernovas represent the deaths of stars, which collapse in powerful explosions. They generally are classified into two main types; the new class, called Type Iax, “is essentially a mini-supernova,” said lead researcher Ryan Foley,…
The rate of star formation in the universe has dropped to just 3% of its long-ago peak, and there’s no end in sight to the decline, a new study finds. A team of astronomers has determined that the rate of star birth peaked around 11 billion years ago, just 2.7 billion years after the Big…
Human and chimp brains look anatomically similar because both evolved from the same ancestor millions of years ago. But where does the chimp brain end and the human brain begin? A new UCLA study pinpoints uniquely human patterns of gene activity in the brain that could shed light on how we evolved differently than our…
Across the world, many women drop out of — or never enter — work in the ‘knowledge society’, even after studying science and technology. Low enrollment rates for women in all but the life sciences, and high dropout rates after university (almost a third of women in science), result in not only the loss of…
The search for a far-off twin of Earth has turned up two of the most intriguing candidates yet. Scientists say these new worlds are the right size and distance from their parent star, so that you might expect to find liquid water on their surface. It is impossible to know for sure. Being 1,200 light-years…
