Sharks have been around for more than 400 million years — but not all sharks are equally resilient to changes around them. Why do some groups thrive, while others dwindle?
Resource rich African countries do not have to fall victim to the resource curse.
Natural resource abundance in a country should not translate into a curse.
The bodies of comb jellies like Mertensia ovum are soft, meaning they rarely fossilize.
Fossilized comb jellies, or ctenophores, are rare because the creatures are almost completely soft-bodied. Rare fossil finds are helping us learn more about ancient animals and evolution.
Jeremy Renner in The Hurt Locker.
In a time of increasingly complex geopolitical entanglements and moral failings, these films articulate a yearning for unsullied heroism, effective leadership and appropriate responses to crises.
Viral memes and catchphrases can turn personal experiences into a political expression of shared awareness.
It’s not just issues like climate change and vaccines that pose problems for conservative thinkers – it’s the way science itself is conducted.
Masai giraffes in northern Tanzania.
Giraffe numbers have plummeted from an estimated 150,000 in 1985 to fewer than 100,000 today.
There have been some shockingly bad graphs circulating during the pandemic.
Bulbophyllum alkmaarense: New Guinea is home to more than 2,400 species of native orchids.
With tarantula-like orchids and giant bananas, New Guinea is officially the most floristically diverse island in the world.
They stumble around, baying for assistance, hoping to drink the lifeblood of other companies’ financial aid.
Is this for wheel?
Starting to feel a little more optimistic? Look away now.
Gandum yang digiling berarti berkurangnya kerusakan gigi pada manusia neolitikum yang juga berefek pada bahasa.
Penelitian baru kami menunjukkan bahwa perspektif biologis memang diperlukan untuk menjelaskan mengapa bahasa memiliki jangkauan suaranya masing-masing.
Milling grain meant less wear and tear on neolithic teeth, which had other effects on language.
Considering language from a biological perspective led researchers to the idea that new food processing technologies affected neolithic human beings’ jaws – and allowed new language sounds to emerge.
Many universities use tutorials to complement lectures.
As students return to campuses this week, new research shows universities could save money by not asking professors to teach tutorials because they are no more effective than student instructors.
While some are declaring that democracy has had its day, others see this as a time to develop more truly democratic ways of living.
Gustav Klimt, Death and Life, 1910
Is it really time to eulogise democracy, or are we rather on the cusp of a new phase in its long and varied life?
The European goldfinch, with its wonderful coloration and melodic singing, is a favoured pet for people living in the western Maghreb. But continued poaching is putting the species in danger.
There is little evidence that training alone reduces the propensity for over-service of alcohol.
Responsible Service of Alcohol laws should be coupled with public discussion that encourages people to take responsible for their own drinking behaviour.
The hormone oestrogen may play a role in a woman’s ability to perform two tasks at the same time.
In men and older women, a complicated thinking test appeared to overwhelm the part of the brain also responsible for moving one of their arms. They could only do one or the other.
Screenshot of a fiction movie researchers used to debate genital cutting among families they worked with in Sudan.
In Sudan, female genital cutting is common among many communities. The use of movies that debate this question could change people’s opinions about the practice.
La « théorie de l’océan gluant » où les méduses envahiraient les mers du globe n’est pas très rigoureuse… Leçon de science.
