Published Tree plantations can get better with age -- but original habitats are best
(via sciencedaily.com)
Original source 
Older tree plantations can be more attractive to animals who are looking for a new home than younger plantations, according to a new study. In the tropics, older plantations also welcome a greater variety of different plants and animals -- though sadly, Christmas tree plantations do not become more biodiverse over time.
Published Same and different: A new species of pit viper from Myanmar
(via sciencedaily.com)
Original source 
Asian pit vipers of the genus Trimeresurus are notoriously difficult to tell apart and continue puzzling researchers to this day. Some species groups have similar-looking species (different species that look alike), while others exhibit extreme variation within a single species (same species that look different). Scientists have now discovered a new species of pit viper from Myanmar that is both similar and different from its adjacent sister species.
Published AI alters middle managers' work
(via sciencedaily.com)
Original source 
The introduction of artificial intelligence is a significant part of the digital transformation bringing challenges and changes to the job descriptions among management. A study shows that integrating artificial intelligence systems into service teams increases demands imposed on middle management in the financial services field. In that sector, the advent of artificial intelligence has been fast and AI applications can implement a large proportion of routine work that was previously done by people. Many professionals in the service sector work in teams which include both humans and artificial intelligence systems, which sets new expectations on interactions, human relations, and leadership.
Published Unveiling ancient secrets: 3D preservation of trilobite soft tissues sheds light on convergent evolution of defensive enrollment
(via sciencedaily.com)
Original source 
Researchers describe unusual trilobite fossils prepared as thin sections showing the 3D soft tissues during enrollment. The study reveals the soft undersides of enrolled trilobites and the evolutionary mechanism that allows arthropods to enroll their bodies for protection from predators and adverse environmental conditions.
Published Millions of mysterious pits in the ocean decoded
(via sciencedaily.com)
Original source 
The world's ocean are a vast habitat for countless creatures that settle, spawn, dig or feed on the seafloor. They also influence the shape of the ocean floor. How exactly this takes place has been scarcely investigated so far. In an interdisciplinary study, geoscientists, biologists and oceanographers, have examined crater-like depressions on the seafloor of the North Sea. They were able to show that these directly relate to the habitats of porpoises and sand eels, and for the first time provide a conclusive explanation for the importance of vertebrates in shaping the seafloor.
Published Shedding light on the microbiome and kidney stones
(via sciencedaily.com)
Original source 
A new study has found changes in the microbiome in multiple locations in the body are linked to the formation of kidney stones.
Published Cosmic lights in the forest
(via sciencedaily.com)

Supercomputer helped astronomers develop PRIYA, the largest suite of hydrodynamic simulations yet made of large-scale structure in the universe.
Published New larks revealed in Africa
(via sciencedaily.com)
Original source 
Researchers have studied the relationships between five closely related species of larks that occur in Africa south of the Sahara. Two of these have not been observed for decades, so the researchers analyzed DNA from museum specimens, some of which were over 100 years old.
Published Common insect species are suffering the biggest losses
(via sciencedaily.com)
Original source 
Insect decline is being driven by losses among the locally more common species, according to a new study. The meta-analysis of 923 locations around the world notes two significant trends: 1) the species with the most individuals (the highest abundance) are disproportionately decreasing in number, and 2) no other species have increased to the high numbers previously seen. This likely explains the frequent observation that there are fewer insects around now than ten, twenty, or thirty years ago.
Published Using AI, researchers identify a new class of antibiotic candidates
(via sciencedaily.com)
Original source 
Using artificial intelligence, researchers discovered a class of compounds that can kill methicillin-resistant Staphylococcus aureus (MRSA), a drug-resistant bacterium that causes more than 10,000 deaths in the U.S. each year.
Published A trillion scents, one nose
(via sciencedaily.com)
Original source 
A research team has uncovered a previously undetected mechanism in mice -- starring the genetic molecule RNA -- that could explain how each sensory cell, or neuron, in mammalian noses becomes tailored to detect a specific odor chemical.
Published New brain-like transistor mimics human intelligence
(via sciencedaily.com)
Original source 
Researchers develop transistor that simultaneously processes and stores information like the human brain. Transistor goes beyond categorization tasks to perform associative learning. Transistor identified similar patterns, even when given imperfect input. Previous similar devices could only operate at cryogenic temperatures; new transistor operates at room temperature, making it more practical.
Published Meet 'Coscientist,' your AI lab partner
(via sciencedaily.com)
Original source 
An artificial intelligence-driven system has autonomously learned about certain Nobel Prize-winning chemical reactions and designed a successful laboratory procedure to make them. The AI did so in just a few minutes and correctly on its first attempt. According to the authors, this is the first time that a non-organic intelligence planned, designed and executed this complex reaction that was invented by humans.
Published Cells of the future: A key to reprogramming cell identities
(via sciencedaily.com)
Original source 
The intricate process of duplicating genetic information, referred to as DNA replication, lies at the heart of the transmission of life from one cell to another and from one organism to the next. This happens by not just simply copying the genetic information; a well-orchestrated sequence of molecular events has to happen at the right time. Scientists have recently uncovered a fascinating aspect of this process known as 'replication timing' (RT) and how special this is when life commences.

Published Rise of archery in Andes Mountains dated to 5,000 years ago -- earlier than previous research
(via sciencedaily.com)
Original source 
Focusing on the Lake Titicaca Basin in the Andes mountains, anthropologists found through analysis of 1,179 projectile points that the rise of archery technology dates to around 5,000 years ago. Previous research held that archery in the Andes emerged around 3,000 years ago. The new research from UC Davis indicates that the adoption of bow-and-arrow technology coincided with both the expansion of exchange networks and the growing tendency for people to reside in villages.
