Mathematics explains how giant ’whirlpools’ form in developing egg cells
The swirling currents occur when the rodlike structures that extend inward from the cells' membranes bend in tandem, like stalks of wheat caught in a strong breeze, according to a study from the University of Cambridge and the Flatiron Institute. The mechanism of the swirling instability is disarmingly simple, and the agreement between our calculations and experimental observations supports the idea that this is indeed the process at work in fruit fly egg cells Raymond Goldstein Egg cells are among the largest cells in the animal kingdom.

Lockdown compliance improving but low take up of Covid tests ’worrying’
Less than half (43%) of people who developed Covid-19 symptoms say they've requested a test, find UCL researchers as part of the Covid-19 Social Study. Three quarters (75%) of adults aged 60+ who reported experiencing symptoms at least once said they had never requested a test, with just 18% of the same age group saying they requested a test every time they experienced symptoms.

Teeth functioned and evolved in giant mega-sharks
A pioneering study by University of Bristol researchers finds that the evolution of teeth in the giant prehistoric shark Megalodon and its relatives was a by-product of becoming huge, rather than an adaptation to new feeding habits. The iconic extinct Megalodon was the largest shark to ever roam the seas.

Melting icebergs key to sequence of an ice age, scientists find
Scientists claim to have found the ‘missing link' in the process that leads to an ice age on Earth. Melting icebergs in the Antarctic are the key, say the team from Cardiff University, triggering a series of chain reactions that plunges Earth into a prolonged period of cold temperatures. It has long been known that ice age cycles are paced by periodic changes to Earth's orbit of the sun, which subsequently changes the amount of solar radiation that reaches the Earth's surface.

Family court decisions distorted by misuse of key research, say experts
Family courts are misunderstanding and misusing research around how children form close relationships with their caregivers, say an international group of experts. The decisions reached by family courts can have a major impact on a child's life, but as we've seen, these decisions may be based on incorrect understanding and assumptions Robbie Duschinsky Seventy experts from across the globe argue that widespread misunderstandings around attachment research have hampered its accurate implementation, with potentially negative consequences for decisions in family courts.

Climate change damage to the homes of clownfish affects their physiology
The metabolism of clownfish - or anemonefish - decreases when their sea 'homes' are damaged by climate change, according to a new study. The research - led by an international team of scientists from the University of Glasgow and CRIOBE, and published today in Functional Ecology - found that exposure to bleached coral reefs can have a negative effect on the physiology and growth of anemonefish.

Galaxy mergers could limit star formation
Our astronomers have looked nine billion years into the past to find evidence that galaxy mergers in the early universe could shut down star formation and affect galaxy growth. Using a powerful Earth-based telescope they saw that a huge amount of star-forming gas was ejected into the universe by the coming together of two galaxies.
