The teasing temptation of a sugary treat can often get the better of us. But don’t worry, we’re not the only ones. The saccharine substance that our sweet tooth finds so hard to resist is also powerfully seductive to mosquitoes. And according to new research, in helping to keep the pests away from our blood-rich body parts, sugar may for once be good for our health.
Because of their delicate organic and decomposing nature, fossilize fungi are extremely rare. So rare, in fact, that a new discovery has just pushed back the earliest evidence of fungi by at least 500 million years – doubling their age.
The news is grim: According to a report compiled by hundreds of scientists from 50 countries, Earth is losing species faster than at any other time in human history. Thanks to climate change, coastal development and the impacts of activities such as logging, farming and fishing, roughly 1 million plants and animals are facing extinction.
The parasitic wasp can do something special. The insect is able to puncture rotten wood or a fruit and thus lay eggs in larvae that live in these kinds of places. The wasp uses a long tube for this. But this tube is so long that the animal cannot push it into the material itself. The secret is that this "needle", which consists of three separate parts, can pull itself forward.
Insects scuttle, chew and fly through the world around us. Humans rely on them to pollinate plants, prey on insects that we don’t get along with, and to be movers and shakers for Earth’s ecosystems. It’s hard to imagine a world without insects.
Panama disease, an infection that ravages banana plants, has been sweeping across Asia, Australia, the Middle East and Africa. The impact has been devastating. In the Philippines alone, losses have totalled US$400m. And the disease threatens not only the livelihoods of everyone in this US$44 billion industry but also the 400m people in developing countries who depend on bananas for a substantial proportion of their calorie intake.
Billions of migratory birds pass through the night sky each spring and fall. Birds use stars to orient their journey between summer breeding grounds and winter feeding grounds. The artificial lights produced by humans disrupt the migration of birds, often with fatal consequences.
How did complex life arise on Earth about two billion years ago? Research by an international team of scientists from Sweden, the United States, Australia and the Netherlands now provides a new perspective on the matter. In a study published this week in Nature Microbiology, the team presents a new model about the first complex cell types that make up plants, fungi, but also animals and people. They describe how complex cellular life forms developed in evolution through the metabolic integration of simpler cell types.
Though it can still be found in the forests of Europe, the Eurasian lynx has not been seen in the UK for more than 1,000 years. This medium-sized wild cat with its distinctive pointy ears was driven to extinction during the medieval period, thanks to low numbers of its preferred prey, roe deer, as well as a disappearing habitat and excessive hunting. But recently the Lynx UK Trust has argued strongly for its reintroduction.
The human capacity for language divides our species from the rest of the animal kingdom. Language has not only allowed us to conquer all corners of the globe, but to devise writing, mathematics and all things thereafter.
Life in the sea isn’t easy. Talk to most people about the ocean and they are likely to imagine a tropical scene with a stretch of golden sand and warm, clear water. The reality is often quite different – the marine environment can be a surprisingly cold place.
When it comes to making decisions, most of us are influenced to some degree by other people, whether that’s choosing a restaurant or a political candidate. We want to know what others think before we make that choice.
You might have noticed how bright green your plants look after rain. Or you may have been watering your garden this summer, over many hot days and weeks. So, which water is best for your plants? The stuff that falls out of the sky or the water that comes out of the tap?
Scientists who work with live organisms often have to move them between locations. This requires knowing what conditions creatures can tolerate well, and also can involve some unusual packing challenges. Here three researchers explain how they transport butterflies, sea turtles and endangered frogs safely between labs and the outdoors.
Industrial engineers from ‘Technologiecampus Gent ‘(KU Leuven) have developed a module that allows them to map the health of trees online. Using this module trees in a city or park can be monitored online.
Scientists have found remnants of small creatures in Antarctica under a deep layer of ice. The remains were found in mud that was brought up through a borehole. The findings might tell us something about the possibility of life on icy planets or moons
Compared to gene-edited babies in China and ambitious projects to rescue woolly mammoths from extinction, biotech trees might sound pretty tame. But releasing genetically engineered trees into forests to counter threats to forest health represents a new frontier in biotechnology.
