Published Deep-sea mining and warming trigger stress in a midwater jellies
(via sciencedaily.com)
Original source 
The deep sea is home to one of the largest animal communities on earth which is increasingly exposed to environmental pressures. However, our knowledge of its inhabitants and their response to human-induced stressors is still limited. A new study now provides first insights into the stress response of a pelagic deep-sea jellyfish to ocean warming and sediment plumes caused by deep-sea mining.
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.

Original source 
Scientists have pioneered a novel approach to develop intelligent healthcare sensors using various gold nanowires.
Published New computer code for mechanics of tissues and cells in three dimensions
(via sciencedaily.com)
Original source 
Biological materials are made of individual components, including tiny motors that convert fuel into motion. This creates patterns of movement, and the material shapes itself with coherent flows by constant consumption of energy. Such continuously driven materials are called 'active matter'. The mechanics of cells and tissues can be described by active matter theory, a scientific framework to understand shape, flows, and form of living materials. The active matter theory consists of many challenging mathematical equations. Scientists have now developed an algorithm, implemented in an open-source supercomputer code, that can for the first time solve the equations of active matter theory in realistic scenarios. These solutions bring us a big step closer to solving the century-old riddle of how cells and tissues attain their shape and to designing artificial biological machines.
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 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 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 Engineering bacteria to biosynthesize intricate protein complexes
(via sciencedaily.com)
Original source 
Protein cages found in nature within microbes help weather its contents from the harsh intracellular environment -- an observation with many bioengineering applications. Researchers recently developed an innovative bioengineering approach using genetically modified bacteria; these bacteria can incorporate protein cages around protein crystals. This in-cell biosynthesis method efficiently produces highly customized protein complexes, which could find applications as advanced solid catalysts and functionalized nanomaterials.
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 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 
Pancreatic cancer is one of the deadliest types of cancers in humans. It is the fourth leading cause of cancer-related deaths in the western world. The early stages of the disease often progress without symptoms, so diagnosis is usually very late.
