Scientists Successfully Turn Breast Cancer Cells Into Fat to Stop Them From Spreading
Researchers have been able to coax human breast cells to turn into fat cells in a new proof-of-concept study in mice.To achieve this feat, the team exploited a weird pathway that metastasising cancer cells have; their results are just a first step, but it's a truly promising approach.When you cut your finger, or when a foetus grows organs, the cells begin to look less like themselves, and more 'fluid' – changing into a type of called a mesenchyme and then reforming into whatever cells the body needs.This process is called epithelial-mesenchymal transition (EMT) and that cancer...…Researchers have been able to coax human breast cells to turn into fat cells in a new proof-of-concept study in mice.To achieve this feat, the team exploited a weird pathway that metastasising cancer cells have; their results are just a first step, but it's a truly promising approach.When you cut your finger, or when a foetus grows organs, the cells begin to look less like themselves, and more 'fluid' – changing into a type of called a mesenchyme and then reforming into whatever cells the body needs.This process is called epithelial-mesenchymal transition (EMT) and that cancer...WW…

New Research Shows Māori Traveled to Antarctica at Least 1,000 Years Before Europeans
When we think of Antarctic exploration, the narrative is overwhelmingly white. The of mainland Antarctica was attributed to a Russian expedition in 1820, while the first landing on the mainland is attributed to an American explorer in 1821.Now, a new paper by New Zealander researchers suggests that the indigenous people of mainland New Zealand - Māori - have a significantly longer history with Earth's southernmost continent.The research team, led by conservation biologist Priscilla Wehi from Manaaki Whenua Landcare Research, looked at oral histories as well as – meaning research, reports,...…When we think of Antarctic exploration, the narrative is overwhelmingly white.

The menagerie of bacterial and fungal species living among us is ever growing - and this is no exception in low-gravity environments, such as the International Space Station (ISS).Researchers from the United States and India working with NASA have now discovered four strains of bacteria living in different places in the ISS – three of which were, until now, completely unknown to science.Three of the four strains were isolated back in 2015 and 2016 – one was found on an overhead panel of the ISS research stations, the second was found in the , the third was found on the surface of the dining...…The menagerie of bacterial and fungal species living among us is ever growing - and this is no exception in low-gravity environments, such as the International Space Station (ISS).Researchers from the United States and India working with NASA have now discovered four strains of bacteria living in different places in the ISS – three of which were, until now, completely unknown to science.Three of the four strains were isolated back in 2015 and 2016 – one was found on an overhead panel of the ISS research stations, the second was found in the , the third was found on the surface of the dining...WW…

These Ants Suit Up in a Protective 'Biomineral Armor' Never Seen Before in Insects
Ants are pretty organised little creatures. Highly social insects, they know how to forage, build complicated nests, steal your pantry snacks, and generally look after the queens and the colony, all by working together.Leaf-cutter ants turn that cooperation up several notches. Leaf-cutter ant colonies like can contain millions of ants, split into four castes that all have different roles to maintain a garden of fungus that the ants eat.These farming ants might make a top-tier team of gardeners, but that doesn't mean they don't get into the occasional scrap, and living in such large groups...…Ants are pretty organised little creatures.

But the microbial species you can cultivate in a petri dish are only a tiny fraction of the bacteria, and other microorganisms that would have been picked up by the swab - only the ones suited to the conditions you grew them in.The overwhelming majority of them do not like the environments we can provide, and therefore won't obediently grow in a petri dish.Now, an international team of...…Growing microbes in a petri dish is pretty simple – swab basically , wipe it on an agar plate, let it sit for a few days in a warm room and presto!
