Our Murderous Ancestors

Our Murderous Ancestors

Prepared to kill

By Invited Researcher

Could it be that even our hands show traces of having evolved for violence? The unique structure of human hands has been extolled as marvelously adapted for precise control and tool use. But they may also betray in their proportions and structure having been selected for killing. This, at least, is a hypothesis posed by […]

Pluto: ‘recent’ volcanism raises puzzle – how can such a cold body power eruptions?

Pluto: ‘recent’ volcanism raises puzzle – how can such a cold body power eruptions?

Pluto, the Solar System’s largest dwarf planet, just became even more interesting with a report that icy lava flows have recently covered substantial tracts of its surface. In this context, “recently” means probably no more than a billion years ago. That’s old, of course – and there is no suggestion that volcanoes are still active […]

Wait, fish make sounds?

Wait, fish make sounds?

Biology

By Invited Researcher

While they may lack some of the melodic qualities of birds or whales, there are almost 1,000 species of fish that use sounds to communicate, and possibly many more. Yet, despite nearly 150 years of contemporary scientific research into fish sound production, there was no global inventory of fish species known to make sounds. Until […]

Future evolution: from looks to brains and personality, how will humans change in the next 10,000 years?

By Invited Researcher

Humanity is the unlikely result of 4 billion years of evolution. From self-replicating molecules in Archean seas, to eyeless fish in the Cambrian deep, to mammals scurrying from dinosaurs in the dark, and then, finally, improbably, ourselves – evolution shaped us. Organisms reproduced imperfectly. Mistakes made when copying genes sometimes made them better fit to […]

Cod ‘supergenes’ reveal how they are evolving in response to overfishing

Cod ‘supergenes’ reveal how they are evolving in response to overfishing

BiologyEvolutionGenetics

By Invited Researcher

Cod “supergenes” have shed light on how they respond to overfishing, and these supergenes could make them more resilient to other environmental changes. That’s according to a new study published by scientists in Norway. This could be good news, in that cod have genetic architecture in place that will permit them to respond to climate […]

By Invited Researcher

Two years of battling COVID-19 has been bad news for tuberculosis (TB) programmes. Respiratory clinicians and researchers have had their time and focus directed elsewhere. And TB has taken advantage. In 2021, the number of TB deaths rose for the first time in over a decade. The barriers caused by lockdowns and overstretched healthcare systems […]
