A novel, previously unseen self-repair mechanism was reported by a team of researchers at Caltech who studied the moon jellyfish. A lot of animals, mostly invertebrates, grow back their lost limbs after these are bitten off by predators or lost in an accident. The moon jellyfish, however, employs a different tactic altogether: instead of expending a lot of energy to regrow its lost limb, the animal re-arranges the limbs it has left to regain symmetry. Even when it’s left with two limbs out of its initial eight, the jellyfish will still re-arrange itself. This sort of mechanism might prove extremely useful in designing self-repairing robots.
A research group working at the Australian Grains Free Air CO₂ Enrichment facility (AgFace) in Victoria is studying the effect elevated carbon dioxide will have on crops such as wheat, lentils, canola and field pea. They grow experimental crops in the open, surrounded by thin tubes that eject carbon dioxide into the air around the plants. Findings show that crops have higher yield (up to 25% more), but less proteins. Elevated CO2 also seems to ruin bread made from the grown wheat.
Wild bees provide environmental services worth $3,250 (€2,880) per hectare per year – accounting for billions, globally. Writing in Nature Communications, study authors quantify how much bees are doing for us, and stress that despite all their immense value, we still don’t have a concrete plan to stop their numbers from dwindling.
We tend to think of the Earth’s water as an inexhaustible resource; after all, you learn the basic water cycle in first grade – water moves from the rivers to the oceans and then evaporates into the atmosphere and then it comes back as rain – so how could it be disappearing? Well, the reality is much more complex than that, and as two different studies showed, we may actually be heading towards a major water crisis.
Among the best thing about being a biologist is you get to name things when you discover it. Now, a marine researcher in California will name one of the cutest invertebrates we’ve ever seen: so adorable, that it might actually be named ‘adorabilis’.
In only 15 years, renewable energy (wind, solar, hydro) could surpass fossil fuels as the main provider of energy. According to a new International Energy Agency (IEA) report, renewables could provide more than 50% of the energy market by 2050. But even so, they warn, without bolder emission cuts, we’ll be blowing past our current climate targets.
Ocean acidification, one of the often ignored dangers associated with climate change is becoming increasingly worrying. As our climate becomes hotter and hotter, the oceans become more and more acidic, and this threatens some animals’ ability to create and maintain carbonatic shells.
It seems rather obvious to me, but there was a lot of debate regarding how a country’s politics affect its emissions – for better or for worse. A new study published in the journal Proceedings of the National Academy of Sciences found that environmental policies in the US have had a significant impact on emissions from 1990 to present days. Despite growing
Yes, you read this right, this is not a snake – it’s not even slightly related to a snake. The animal portrayed above has developed a technique called mimicry – when an animal evolves in such a way to imitate another, usually to protect itself. The animal above is called Dynastor darius darius, and was first described all the way back in
The U.S. Fish and Wildlife Service reports it has classed all chimpanzees, whether captive or wild, under the Endangered Species Act. Previously, chimpanzees kept captive in labs for biomedical research, entertainment or as pets were classed as “threatened”.The USFWS director Dan Ashe agrees that this has transmitted an erroneous mixed message to the public. Whether captive (and hopefully cared for) or living in the wild, all chimps belong the same species, and this species is definitely endangered and in dire need of help.
