, 2018 Parallel evolution across replicate populations has provided evolutionary biologists with iconic examples of adaptation. When multiple populations colonize seemingly similar habitats, they may evolve similar genes, traits, or functions.

Advanced Science, EarlyView.This double‐blind, placebo‐controlled study demonstrates that intranasal oxytocin reduces subjective fear in immersive, naturalistic social (but not non‐social) contexts. Concomitant fMRI reveals that oxytocin enhances middle cingulate activity and amygdala connectivity while it modulates network‐level connectivity and attenuates reactivity of a brain ...

Contained semi-field environments for ecological studies on transgenic African malaria vectors: benefits and constraints [PDF]
New interventions are needed to reduce the burden of vector-borne diseases like malaria and dengué, which are among the most serious and prevalent infectious diseases worldwide. The release of genetically modified (GM) mosquitoes may offer an alternative

Structural Variations Associated with Adaptation and Coat Color in Qinghai‐Tibetan Plateau Cattle
Advanced Science, EarlyView.This study reveals the landscape of structural variants in Qinghai‐Tibetan Plateau cattle through long‐read sequencing. Discoveries include metabolic and oxygen‐regulation gene variants, along with a 2‐Mb KIT‐containing inversion and translocations responsible for cattle gray coat. These findings highlight the significant role of structural variants in

Advanced Science, EarlyView.This study deciphers maternal‐driven microbial transmission in pigs using a deep learning model (maternal–offspring microbial transmission model), identifying Christensenellaceae R‐7 group as a key transmitted taxon. Filtered galacto‐oligosaccharides‐targeted Christensenellaceae R‐7 group alters offspring microbial functions via maternal ...

Ecologic observations on anopheline vectors of malaria in the Brazilian Amazon.
The American journal of tropical medicine and hygiene, 1998 Human intervention in the Brazilian Amazon region promotes contacts between humans and vectors that may favor the propagation of anopheline mosquitoes and the spread of malaria in the absence of planning and infrastructure to control this disease. Vector ecology studies were carried out to determine the risk areas.

Advanced Science, EarlyView.Here, a decision‐making mechanism underlying mechanical adaptation is demonstrated. This study demonstrates that cellular adaptation to mechanical stress can be induced by applying low‐amplitude stretch to cells. When the stretch reaches a critical amplitude threshold, it triggers Ca2⁺‐dependent positive feedback, which induces cholesterol efflux and ...

Environmental Noise Variability in Population Dynamics Matrix Models [PDF]
, 2009 The impact of environmental variability on population size growth rate in dynamic models is a recurrent issue in the theoretical ecology literature. In the scalar case, R.

A Novel nor@DHB Matrix for Direct Microbial Analysis in Lung Cancer Tissues
Advanced Science, EarlyView.Integrated matrix‐assisted laser desorption/ionization mass spectrometry workflow quantifies intratumoral microbes in lung cancer through lipopolysaccharide/lipid A extraction from biopsies. The novel ionic matrix called norharmane conjugated to 2,5‐dihydroxybenzoic acid enhances lipid A ionization, enabling direct detection of bacterial genera ...

Health and sustainable development [PDF]
, 2001 If sustainable development is to mean anything, people must be healthy enough to benefit from it and not have their lives cut off prematurely. Development without health is meaningless.
