Published Genomic study sheds light on how carnivorous Asian pitcher plants acquired signature insect trap
(via sciencedaily.com)
Original source 
Scientists sequenced the genome of the East Asian pitcher plant, Nepenthes gracilis, a species of carnivorous plant related to Venus flytraps, as well as sundews, beets and spinach.
Published Sea fireflies synchronize their sparkle to seek soulmates
(via sciencedaily.com)
Original source 
In sea fireflies' underwater ballet, the males sway together in perfect, illuminated synchronization, basking in the glow of their secreted iridescent mucus.
Published Rare ant species rediscovered in North Carolina trees
(via sciencedaily.com)
Original source 
There's a species of ant that is so rare, only a handful of records exist from across the entire eastern United States. North Carolina State University researcher Michelle Kirchner not only found these ants in the Triangle region of North Carolina, she is the first to document an entire colony for scientists, taxonomists and ant-thusiasts everywhere. It is the first time males of the species have been collected or photographed.
Published Broadband buzz: Periodical cicadas' chorus measured with fiber optic cables
(via sciencedaily.com)
Original source 
Through an emerging technology called distributed fiber optic sensing, cables bringing high-speed internet to American households can be used to detect temperature changes, vibrations, and even sound. And periodical cicadas -- the insects that emerge by the billions every 13 or 17 years and make a racket with their mating calls -- are loud enough to be detected. A new study shows how fiber optic sensing could open new pathways for charting populations of these famously ephemeral bugs.
Published The waxy surface protecting plants might hold the key to developing stronger crops
(via sciencedaily.com)
Original source 
Researchers have discovered that the waxy protective barrier around plants might play a role in sending chemical signals to other plants and insects.
Published Inoculation against diseased fields
(via sciencedaily.com)
Original source 
Farmland often harbors a multitude of pathogens which attack plants and reduce yields. A research team has now shown that inoculating the soil with mycorrhizal fungi can help maintain or even improve yields without the use of additional fertilizers or pesticides. In a large-scale field trial, plant yield increased by up to 40 percent.
Published Landscape dynamics determine the evolution of biodiversity on Earth
(via sciencedaily.com)
Original source 
A landmark study into the geological timescale distribution of sediment and nutrients over 500 million years shows that species biodiversity on Earth is driven by landscape dynamics.
Published Flower power on Indian farms helps bees and boosts livelihoods
(via sciencedaily.com)
Original source 
Planting flowers beside food crops on farms in India attracts bees, boosts pollination and improves crop yield and quality, researchers have found.
Published Slash-and-burn agriculture can increase forest biodiversity, researchers find
(via sciencedaily.com)
Original source 
The slash-and-burn agriculture practiced by many Indigenous societies across the world can actually have a positive impact on forests, according to a new study done in Belize. Researchers found that in areas of the rainforest in which Indigenous farmers using slash-and-burn techniques created intermediate-sized farm patches -- neither too small nor too large -- there were increases in forest plant diversity.
Published Sensitive ecosystems at risk from mine waste
(via sciencedaily.com)
Original source 
Nearly a third of the world's mine tailings are stored within or near protected conservation areas, new research has found.
Published Was 'witchcraft' in the Devil's Church in Koli based on acoustic resonance? The crevice cave has a unique soundscape
(via sciencedaily.com)
Original source 
The national park of Koli in eastern Finland is home to a famous, 34-metre-long crevice cave known as Pirunkirkko, or Devil's Church in English. A new study investigates the acoustics of the Devil's Church and explores whether the acoustic properties of the cave could explain the beliefs associated with it, and why it was chosen as a place for activities and rituals involving sound.
Published Wave devouring propulsion: A revolutionary green technology for maritime sustainability
(via sciencedaily.com)
Original source 
A new form of wave devouring propulsion (WDP) could power ships and help to cut greenhouse gas emissions in the maritime industry.
Published Sophisticated swarming: Bacteria support each other across generations
(via sciencedaily.com)
Original source 
When bacteria build communities, they cooperate and share nutrients across generations. Researchers have been able to demonstrate this for the first time using a newly developed method. This innovative technique enables the tracking of gene expression during the development of bacterial communities over space and time.
Published AI finds formula on how to predict monster waves
(via sciencedaily.com)
Original source 
Using 700 years' worth of wave data from more than a billion waves, scientists have used artificial intelligence to find a formula for how to predict the occurrence of these maritime monsters. Long considered myth, freakishly large rogue waves are very real and can split apart ships and even damage oil rigs.
Published Protect delicate polar ecosystems by mapping biodiversity
(via sciencedaily.com)
Original source 
Concerted action is required to mitigate the impact of warming on polar ecosystems and sustainably manage these unique habitats.
Published Nature photographers posting to social media help with protecting biodiversity
(via sciencedaily.com)
Original source 
Nature photographers posting to social media are helping improve biodiversity conservation mapping in South Asia, and the method could go global.
Published Much more than waste: Tiny vesicles exchange genetic information between cells in the sea
(via sciencedaily.com)
Original source 
Researchers take a look at data that has so far been mostly discarded as contamination, revealing the previously underestimated role of extracellular vesicles (EVs). These are important for the exchange of genetic information between cells and thus for the microbial community in the sea.
Published New study reveals huge potential for future waves of invasive species
(via sciencedaily.com)
Original source 
Human trade and transport have led to the intentional and accidental introductions of non-native species outside of their natural range globally. These biological invasions can cause extinctions, cost trillions, and spread diseases. A study has investigated how many of these non-native species already exist worldwide and which species groups are particularly prone to become non-native.
Published Previously unknown luminescence revealed in ten deep sea species and an order of sea cucumbers
(via sciencedaily.com)
Original source 
Researchers present evidence of previously unknown luminosity in 10 deep-sea species, suggesting underestimated diversity. These new discoveries include a member of the order Molpadia, which was previously thought not to be luminescent. The authors stress the importance of considering the ecological role of bioluminesence and the need for conservation.
Published 'Bouncing' comets could deliver building blocks for life to exoplanets
(via sciencedaily.com)
Original source 
How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers have shown how comets could deposit similar building blocks to other planets in the galaxy.
