Published Long in the Bluetooth: Scientists develop a more efficient way to transmit data between our devices
(via sciencedaily.com) Original source Researchers have developed a more energy efficient way of connecting our personal devices. New technology consumes less power than Bluetooth and can improve battery life of tech accessories, including earbuds and fitness trackers. Future applications could see us unlocking a door by touching its handle or shaking hands to exchange phone numbers.
Published Forest modeling shows which harvest rotations lead to maximum carbon sequestration
(via sciencedaily.com) Original source Forest modeling shows that a site's productivity -- an indicator of how fast trees grow and how much biomass they accumulate -- is the main factor that determines which time period between timber harvests allows for maximum above-ground carbon sequestration.
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 New research suggests plants might be able to absorb more CO2 from human activities than previously expected
(via sciencedaily.com) Original source New research paints an uncharacteristically upbeat picture for the planet. This is because more realistic ecological modelling suggests the world's plants may be able to take up more atmospheric CO2 from human activities than previously predicted.
Published Scientists have solved the damselfly color mystery
(via sciencedaily.com) Original source For over 20 years, a research team has studied the common bluetail damselfly. Females occur in three different color forms -- one with a male-like appearance, something that protects them from mating harassment. In a new study, an international research team found that this genetic color variation that is shared between several species arose through changes in a specific genomic region at least five million years ago.
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 Pushing the boundaries of eco-friendly chemical production
(via sciencedaily.com) Original source A team of pioneering researchers has made a significant leap forward in the complex world of molecular chemistry. Their focus? Azaarenes, unique molecular puzzle pieces crucial to many everyday products, from eco-friendly agrochemicals to essential medicines. The team developed an innovative way to modify these molecules using light-powered enzymes -- a groundbreaking discovery that holds promise for new industrially relevant chemical reactions and sustainable energy solutions.
Published Temperature variability reduces nesting success
(via sciencedaily.com) Original source Many songbirds are nesting earlier in spring because of warmer temperatures brought about by climate change. But the shift brings another danger that is especially deadly for nestlings: greater exposure to temperature variability in the form of cold snaps and heat waves.
Published New global stocktake: Healthy forests could store much more carbon
(via sciencedaily.com) Original source Natural carbon reservoirs will play a major role at the COP28 world climate conference in the United Arab Emirates. In a recent study, a team of more than two hundred researchers worldwide presents new estimates of the storage potential of forests around the globe. According to the study, forests could ideally absorb 328 billion tons (gigatons, Gt for short) of carbon. However, as many formerly forested areas are now used for agriculture and as settlement areas, the potential is reduced to 226 Gt. 139 Gt of this (61%) could be achieved by protecting existing forests alone. The remaining 87 Gt (39%) could be realized by reconnecting previously fragmented forest landscapes and managing them sustainably.
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 Hydrogen fuel can be a competitive alternative to gasoline and diesel today
(via sciencedaily.com) Original source Energy researchers posit hydrogen fuel can potentially be a cost-competitive and environmentally friendly alternative to gasoline and diesel, and that supplying hydrogen for transportation in the greater Houston area can be profitable today.
Published No one-size-fits-all solution for the net-zero grid
(via sciencedaily.com) Original source As power generation from sources like solar and wind increases, along with the introduction of devices such as heat pumps and batteries, a new optimization tool will help the UK plan for a greener electricity network. The researchers developed an algorithm to model how these smaller networks distributed electricity -- factoring in how local grids could become unbalanced by adding too many heat pumps in a single area or generating more electricity than the grid could accept.
Published Nuclear expansion failure shows simulations require change
(via sciencedaily.com) Original source A team of researchers looked back at a model that predicted nuclear power would expand dramatically in order to assess the efficacy of energy policies implemented today.
Published Plants that survived dinosaur extinction pulled nitrogen from air
(via sciencedaily.com) Original source Ancient cycad lineages that survived the extinction of the dinosaurs may have done so by relying on symbiotic bacteria in their roots to fix atmospheric nitrogen. The finding came from an effort to understand ancient atmospheres, but became an insight into plant evolution instead.
Published Pseudoscorpions of Israel: Two new family records discovered
(via sciencedaily.com) Original source A recent study has unveiled two previously undiscovered families of Pseudoscorpions in Israel. Positioned at the convergence of three continents, Israel's distinct biodiversity has undergone systematic revision, resulting in an updated checklist featuring 61 pseudoscorpion species across 28 genera and fourteen families. This pioneering research includes the introduction of the first illustrated identification key, based on morphological characters, accompanied by distribution maps. Notably, the study highlights the discovery of two new family records in Israel -- Syarinidae and Cheiridiidae -- both with a cosmopolitan distribution, including in the Mediterranean region. The findings significantly enhance our comprehension of regional biodiversity, offering crucial resources for forthcoming ecological, taxonomical and conservation endeavors. Furthermore, several undescribed species identified in this paper will be comprehensively described in separate publications, further advancing the field of pseudoscorpion taxonomy.
Published Water splitting reaction for green hydrogen gas production improved
(via sciencedaily.com) Original source Electrochemical catalysts used in water splitting often show poor performance due to low electrical conductance of (oxy)hydroxide species produced in situ. To overcome this challenge, researchers have now designed an electrode with Schottky Junction formed at the interface of metallic Ni-W5N4 and semiconducting NiFeOOH. The proposed electrode shows excellent catalytic activity and can facilitate industrial seawater splitting continuously for 10 days.
Published New scientific study reveals the crucial role of herbivorous fishes and sea urchins in restoring Caribbean coral reefs
(via sciencedaily.com) Original source A new study presents crucial findings on the feeding preferences of herbivorous fishes and the sea urchin Diadema antillarum in Little Cayman. The study sheds new light on the dynamics of these herbivores and their impact on the resilience of Caribbean coral reefs.

(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.
