Published Researchers unearth a new process by which algae pass on nurtrients to their coral host
(via sciencedaily.com) 
Researchers have identified a new pathway by which sugar is released by symbiotic algae. This pathway involves the largely overlooked cell wall, showing that this structure not only protects the cell but plays an important role in symbiosis and carbon circulation in the ocean.
Published Hot chemistry quickly transforms aromatic molecules into harmful aerosols
(via sciencedaily.com) 
A research group has established key early steps in the conversion of aromatic molecules, a major constituent of traffic and other urban volatile emissions, into aerosol. Their findings increase understanding of the chemical processes that degrade urban air quality and influence climate change.
Published Research group detects a quantum entanglement wave for the first time using real-space measurements
(via sciencedaily.com) 
A team has created an artificial quantum magnet featuring a quasiparticle made of entangled electrons, the triplon.
Published New approach to nongenetic T-cell-based immunotherapy
(via sciencedaily.com) 
Immunotherapies for cancer aim to induce the immune system to combat cancer cells more effectively. A research team has now described a new, modular strategy for T-cell-based immunotherapy that manages to work without complex genetic modifications. Modulation of cell-cell communications through an ingenious regulatory circuit using various small, specially folded DNA molecules (aptamers) causes cancer cells to directly activate their mortal enemies, T cells.
Published Solar powered irrigation: A game-changer for small-scale farms in sub-Saharan Africa
(via sciencedaily.com)
Original source 
A new study finds that standalone solar photovoltaic irrigation systems have the potential to meet more than a third of the water needs for crops in small-scale farms across sub-Saharan Africa.
Published Tree mortality in the Black Forest on the rise -- climate change a key driver
(via sciencedaily.com)
Original source 
Climate impacts such as dry, hot summers reduce the growth and increase the mortality of trees in the Black Forest because they negatively influence the climatic water balance, i.e., the difference between precipitation and potential evapotranspiration. That is the central finding of a long-term study of the influence of climate and climate change on trees in the Black Forest.
Published Barnacles may help reveal location of lost Malaysia Airlines flight MH370
(via sciencedaily.com)
Original source 
Geoscientists have created a new method that can reconstruct the drift path and origin of debris from flight MH370, an aircraft that went missing over the Indian Ocean in 2014 with 239 passengers and crew.
Published Scientists develop fermionic quantum processor
(via sciencedaily.com) 
Researchers have designed a new type of quantum computer that uses fermionic atoms to simulate complex physical systems. The processor uses programmable neutral atom arrays and is capable of simulating fermionic models in a hardware-efficient manner using fermionic gates. The team demonstrated how the new quantum processor can efficiently simulate fermionic models from quantum chemistry and particle physics.
Published Biologist gets the scoop on squash bug poop
(via sciencedaily.com)
Original source 
A discovery about how a common insect acquires a microbe that is essential for its growth may help in the control of an agricultural pest.
Published Newly discovered 'primitive cousins of T rex' shed light on the end of the age of dinosaurs in Africa
(via sciencedaily.com)
Original source 
Researchers have discovered the fossils of two new abelisaurs in Morocco, showing the diversity of dinosaurs in this region at the end of the Cretaceous period.
Published Buffalo slaughter left lasting impact on Indigenous peoples
(via sciencedaily.com)
Original source 
The near extinction of the North American bison in the late 1800s caused a devastating, lasting economic shock to Indigenous peoples whose lives depended on the animals, an economic study finds.
Published Day-plus-night cooling strategies provide a powerful and cost-effective option against heat stress for dairy cows outdoors
(via sciencedaily.com)
Original source 
Researchers have demonstrated the effectiveness of extending cooling strategies for dairy cows throughout the day and night, including how these strategies could be applied to outdoor herds with a more limited physical infrastructure.
Published Noncoding DNA explains a majority of the heritability of dairy cattle traits, like milk production and fertility
(via sciencedaily.com)
Original source 
Regulatory genes -- genes that control how other genes are used -- are responsible for 69% of the heritability of dairy cattle traits such as milk production and fertility, according to a new study. This contribution is 44% more than expected and much higher than previous studies of regulatory genes in humans. The findings, reported by a team of animal and human geneticists, could improve the efficiency of agricultural breeding programs. The study also helps solve the longstanding mystery of why mammalian genomes contain so much noncoding DNA.
Published Biodiversity protects against invasions of non-native tree species
(via sciencedaily.com) 
Researchers combined human and ecological factors to analyze the global scale of non-native tree species invasions. Human activity in hotspots of global trade, such as maritime ports, is linked to an increased likelihood of non-native tree species invasions. However, a high diversity of native tree species can help to curb the intensity of such invasions.
Published A 21st century mining boom across the tropics is degrading rivers
(via sciencedaily.com)
Original source 
Gold and mineral mining in and near rivers across the tropics is degrading waterways in 49 countries, according to a new study. Published in Nature, the findings represent the first physical footprint of river mining and its hydrological impacts on a global scale.
Published Vegetarian diet of corals explains age-old mystery dating back to Darwin
(via sciencedaily.com)
Original source 
A new study has revealed why coral reefs can thrive in seemingly nutrient poor water, a phenomenon that has fascinated scientists since Charles Darwin.
Published Atmospheric circulation weakens following volcanic eruptions
(via sciencedaily.com)
Original source 
An international team of scientists found that volcanic eruptions can cause the Pacific Walker Circulation to temporarily weaken, inducing El Niño-like conditions. The results provide important insights into how El Niño and La Niña events may change in the future.
Published How artificial intelligence gave a paralyzed woman her voice back
(via sciencedaily.com) 
Researchers have developed a brain-computer interface (BCI) that has enabled a woman with severe paralysis from a brainstem stroke to speak through a digital avatar.
Published Graphene discovery could help generate hydrogen cheaply and sustainably
(via sciencedaily.com) 
Researchers have finally solved the long-standing puzzle of why graphene is so much more permeable to protons than expected by theory.
Published Fungus gnats as pollinators not pests
(via sciencedaily.com)
Original source 
Many plants and crops rely on insects to pollinate them so they can reproduce. A new study has shown that several flowering plants from the group Euonymus are pollinated by fungus gnats, a dipteran insect. Specifically, they pollinate Euonymus plants which have red-petaled flowers with short stamens and yogurt-like scent. Although fungus gnats are known to pollinate hundreds of plant species, this study shows that the particular traits of red Euonymus flowers were likely to have been acquired via pollination syndrome, evolving over a process of natural selection to be pollinated specifically by fungus gnats. This research highlights the important role of Diptera, which are commonly regarded as pests, in plant diversity and evolution.
