The Science Quiz: The stuff semiconductors are made of

Questions: 1. Cubic boron arsenide is an ____________ semiconductor, meaning it can efficiently transport both electrons and holes. Fill in the blank. 2. Graphene lacks a critical property called a natural _______. This lacuna poses a significant challenge to its use as a traditional semiconductor despite its excellent electrical conductivity, high thermal conductivity, flexibility, and…

Could rotating black holes be the wind turbines powering the distant future?

The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of our Milky Way black hole released in 2022, has captured a new view of the massive object at the centre of our Galaxy: how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a…

Scientists are using ancient DNA to reveal the Iberian lynx’s ‘weapon’ against extinction

Scientists are using ancient DNA to reveal the Iberian lynx’s ‘weapon’ against extinction

Many large mammals have lost genetic diversity, often thanks to the actions of people shrinking their populations. The implications can be severe because without genetic diversity, a population does not have a “genetic database” to fall back on to adapt to environmental change. The Iberian lynx (Lynx pardinus) is no stranger to this reduction in diversity. Human…

Extinct volcanoes could help sate humanity’s hunger for rare earth elements

Scientists found that some rare magma types are surprisingly efficient at concentrating rare earth elements. | Photo Credit: Shutterstock Extinct volcanoes are hard to study – we never see them erupt. Using a unique experimental technique, we were able to recreate a certain type of extinct volcano in a lab, learning more about the magma…

Evolution can change how an ecosystem collapses, study finds

Dying coral reefs, rainforests transforming into savannas, grasslands turning into deserts – these are ecosystem “tipping points”, boundary lines we’re desperate not to cross. In dynamic systems filled with life, these critical thresholds aren’t set in stone. Since organisms can evolve, the tipping points within these ecosystems might evolve too. Most of us think of…
