New study warns that melting Arctic sea-ice could affect global ocean circulation

A recent study suggests that enhanced Arctic sea-ice melting during the Last Interglacial period led to significant cooling in northern Europe. The researchers used sediment cores and geochemical tracers to reconstruct past ocean conditions, highlighting the importance of feedback mechanisms in the climate system.

Magicians don’t mind sharing the secrets behind tricks – if they are their own

A new study reveals that magicians are willing to share their own trick techniques, but not those invented by others or deceased individuals. They believe it's acceptable to reveal secrets for good causes, such as enhancing wellbeing or scientific research, and that mass online tutorials have reduced the need for traditional secrecy.

Ancient giant cicadas reveal an aerial evolutionary arms race

A recent study on global giant cicadas reveals an aerial evolutionary arms race between Palaeontinidae and birds. The research suggests that the rise of birds imposed greater predation pressure on insects, driving the evolution of more advanced flight capabilities in late Palaeontinidae.

No incentive for older birds to make new friends

Researchers studied an isolated population of sparrows on Lundy Island and found that older birds tend to have fewer friends, similar to humans. The study suggests that there is no 'evolutionary pressure' to maintain social connections in older age, leading to a decline in friendships.
