Lions making fewer zebra kills due to ‘chain reaction’ involving invasive ants
Hunting by Kenyan lions impeded in ‘ecological chain reaction’ as big-headed ants fail to stop elephants stripping acacia trees – the cats’ ambush coverWhen a lion decides to chase down a zebra it seems as though nothing can stop it. But now researchers have discovered these enormous predators are being thwarted by a tiny foe: ants.Scientists have found the spread of big-headed ants in east Africa sets off a situation leading to lions making fewer zebra kills.Continue reading...

I discovered a tiny frog that lives its whole life inside one plant
Everyone told me there is no water on top of this Brazilian mountain, there won ’t be any frogs. Now I’ve dedicated my life to preserving this incredible speciesI remember the park rangers saying: “Why are you going up there? There is no water on the top, and you’re not going to find any frogs.” I said: “Well I’m going to check it out.”The Espinha ço mountain range in the east of Brazil is a very special place, and it’s mostly unknown. My house looks on to the mountain in Pico do Itambé state park, so I have my breakfast looking at it each morning. You’re surrounded by thunderstorms and strong winds, ...

Secrets of the microbiome: the vagina – podcast
The trillions of microbes living on and inside the human body are an important part of who we are, from mediating all our interactions with the environment to determining our cancer risk and influencing who we fall for. And scientists are only just beginning to decipher the species of bug we share our lives with, and how they shape us.In the second of a three-part Science Weekly mini-series, Madeleine Finlay meets Ina Schuppe Koistinen, associate professor at the Karolinska Institutet in Stockholm, and author of the book Vulva: Facts, Myths and Life-Changing Insights. Ina explains what makes the vaginal microbiome special,...

Microbes that gave rise to all plants and animals became multicellular 1.6 billion years ago, tiny fossils reveal
A new study describing a microscopic, algalike fossil dating back more than 1.6 billion years supports the idea that one of the hallmarks of the complex life we see around us—multicellularity— is much older than previously thought. Together with other recent research, the fossil, reported today in
Science Advances
, suggests the lineage known as eukaryotes— which features compartmentalized cells and includes everything from redwoods to jellies to people—
became multicellular some 600 million years earlier than scientists once generally thought
.
“It’s a fantastic paper,” says Michael...

Just two northern white rhinos remain. The species ’ first IVF pregnancy could save them from extinction
The first successful embryo transfer in a southern white rhino paves way for using technique to save rarer northern cousinsThe critically endangered northern white rhino could be saved from the brink of extinction after scientists performed the first successful embryo transfer in white rhinos.After the last male northern white rhino, Sudan, died in 2018, the disappearance of the species looked imminent. Just twoinfertile female northern white rhinos– Fatu and Najin – remain, and are under 24-hour armed protection at a conservation reservation in Kenya. But a new scientific advancement means the mother and daughter may ...

Nomogram combines ultrasound features to assess thyroid nodules
A nomogram combining ultrasound features and TI-RADS parameters can differentiate between malignant and benign thyroid nodules, according to research published January 22 in Ultrasound in Medicine & Biology.
Investigators led by Lina Pang from Fourth Military Medical University in Xi'an, Shaanxi Province, China found that their nomogram achieved high predictive performance in evaluating TI-RADS thyroid nodules categories 3, 4, and 5.
“A method of integrating information from multiple ultrasound modalities should be developed to improve diagnostic accuracy as a further supplementary tool for the risk stratification perf...

Nobel laureates call on EU to relax rules on genetic modification
Open letter says lawmakers must ‘reject fearmongering’ and allow scientists to develop crops that can withstand ‘climate emergency’The EU must “reject the darkness of anti-science fearmongering” before a key vote on gene editing, 34 Nobel prize winners have said.In anopen letter shared with the Guardian and other European newspapers, the laureates demanded that lawmakers relax strict rules on genetic modification to embrace new techniques that target specific genes and edit their code. The technology could make crops more resistant to disease and more likely to survive extreme weather events that are growing mo...

Slimy hagfish help solve mysteries of genome duplication
With an eyeless face and slimy body that only a mother could love, hagfish fascinate many biologists. These eel-like, jawless vertebrates have now helped scientists solve a major evolutionary mystery: When did vertebrate genomes double in size and what happened as a result?
It’s long been known that in the past, various plants and animals duplicated all their genes in one fell swoop. By sequencing hagfish genomes for the first time, two teams working independently have clarified when two of these genomic upheavals occurred in the early history of vertebrates. In addition to helping explain some of the hagfish’s u...
