The Climate-Driven Mass Extinction No One Had Seen

Sixty-three percent. That’s the proportion of mammal species that vanished from Africa and the Arabian Peninsula around 30 million years ago, after Earth’s climate shifted from swampy to icy. But we are only finding out about it now. Compiling decades of work, a new study published this week in the journal Communications Biology reports on […]

Mars: Jezero crater really was a lake

The first published data from the Perseverance rover shows that there was a large, deep lake on Mars 3.6 billion years ago, and that it was swept away by a climate upheaval. After years of preparation and the nerve-wracking take-off and landing phases, the publication of the very first results of a space mission is […]

Study finds medical debt is a double whammy for the poor

Earlier this summer, Stanford economist Neale Mahoney sounded an alarm with a study he coauthored: Americans have at least $140 billion in unpaid health care bills sitting in collection agencies – making the country’s medical debt crisis far bigger than anyone had realized. Now, in plumbing the repercussions, his latest research finds evidence suggesting that people saddled with unpaid […]

New process could turn scrap metal into hi-tech steel in demand for cars and alloys

A new process for electrochemically removing carbon from steel during recycling to create ultra-pure low carbon steel has been developed in Canada. The researchers believe that the technology required could potentially be integrated into secondary steel mills, allowing the recycling of high-carbon steel into purer, higher-grade metal more in demand for hi-tech industries. With climate […]

Encourage wealthy and well-connected to use their influence to tackle climate change

A paper published today in the journal Nature Energy identifies five ways that people of high socioeconomic status have a disproportionate impact on global greenhouse gas emissions – and therefore an outsized responsibility to facilitate progress in climate change mitigation. By saying it’s only the super-rich that need to change their behaviour, we ignore the power that others have […]

Crayfish and carp among the invasive species pushing lakes towards ecosystem collapse

Human activity and climate change are causing invasive non-native species to spread rapidly across the globe. Researchers have found that certain invasive species can push lake ecosystems beyond a critical ‘tipping point’, causing a sudden shift from healthy to degraded conditions that is difficult to reverse. Invasive fish such as Asian silver carp Hypophthalmichthys molitrix, and […]

Therapeutic malaria treatment shown to be 100% effective in Phase 2 trial

The fight against one of the world’s deadliest infectious diseases — malaria — may soon have two new weapons. The World Health Organization this week endorsed a vaccine, Mosquirix, made by British pharmaceutical company GlaxoSmithKline, that prevents malaria and, according to The New York Times, “could save the lives of tens of thousands of children in Africa […]

Understanding how humans understand speech

New funding from the National Science Foundation’s Build and Broaden Program will enable a team of researchers from Penn State and North Carolina Agricultural and Technical State University (NC A&T) to explore how speech recognition works while training a new generation of speech scientists at America’s largest historically Black university. Research has shown that speech-recognition […]
