oil-palm and rubber plantations have distinct combinations of soil- and canopy-dwelling organisms compared with rainforests.

recent advances in wearable and implantable biomedical devices have inspired the pursuit of seamless human-machine integration through bioelectronic interfaces (1). such biocompatible interfaces would allow the recording and processing of signals, such as brain and heart activities, in real time. although modern electronics rely on complementary metal-oxide-semiconductor architectures to construct

cancer cells often have abnormal dna content owing to disruption of the pathways that control the cell cycle. cells commit to the cell cycle in response to small peptide signals called mitogens, which ensure entry into s phase, when dna is replicated. once s phase is initiated, the cell cycle is normally self-sustaining and irreversible. however, under certain circumstances, two consecutive rounds

b cells are key players in adaptive immunity. in a typical response, b cells specific for an antigen become activated and proliferate in a transient structure called a germinal center (gc), where their b cell receptor (bcr) undergoes rounds of mutation, and clones with bcrs that bind antigen more robustly are selected. selected gc b cells then become either memory cells, poised to respond to future

considered one of the “big three” global infectious diseases—together with hiv/aids and tuberculosis—malaria caused by plasmodium falciparum and plasmodium vivax continues to substantially affect the poorest communities of sub-saharan africa and southeast asia (1). development of resistance to almost all antimalarial drugs by the parasite, resistance of the anopheles mosquito (which transmits the parasite)

the contest to elect the next president of paris-saclay university has collapsed, reflecting wider issues at the giant research centre.

a deep dive into plant behaviour and consciousness asks why the topic has been taboo for so long, and whether botanists are changing their minds about plants’ cognitive abilities.

the first set of results from a pioneering cosmic-mapping project hints that the repulsive force known as dark energy has changed over 11 billion years, which would alter ideas about how the universe has evolved and what its future will be.

researchers in china say they are finding themselves five to ten years behind their us counterparts as export restrictions bite.

carers need better support from employers, such as paid parental leave, subsidized childcare and relief for other types of caregiving. but is there will among institutions to provide it?

it can be hard when junior scientists feel unsupported. nature asked three scientists for their advice on how to respond.

kidney tissue was transplanted from one rat fetus to another while the recipient was still in its mother’s womb. plus, ‘chatgpt for crispr’ creates new gene-editing tools and a desperate plan to save permafrost from carbon-bomb wildfires.

abstract. cloud feedbacks associated with deep convective anvils remain highly uncertain. in part, this uncertainty arises from a lack of understanding of how microphysical processes influence the cloud radiative effect. in particular, climate models have a poor representation of microphysics processes, thereby encouraging the collection and study of observation data to enable better representation

abstract. in the western arctic ocean lies the largest freshwater reservoir in the arctic ocean, the beaufort gyre. long-term changes in freshwater reservoirs are critical for understanding the arctic ocean, and data from various sources, particularly measured or reanalyzed data, must be used to the greatest extent possible. over the past two decades, a large number of intensive field observations

strigolactones are a class of phytohormones with various functions in plant development, stress responses, and in the interaction with (micro)organisms in the rhizosphere. while their effects on vegetative development are well studied, little is known about their role in reproduction. we investigated the effects of genetic and chemical modification of strigolactone levels on the timing and intensity

ovarian cancer is an aggressive gynecological tumor characterized by a high relapse rate and chemoresistance. ovarian cancer exhibits the cancer hallmark of elevated glycolysis, yet effective strategies targeting cancer cell metabolic reprogramming to overcome therapeutic resistance in ovarian cancer remain elusive. here, we revealed that epigenetic silencing of otubain 2 ( otub2 ) is a driving force

odd viscosity couples stress to strain rate in a dissipationless way. it has been studied in plasmas under magnetic fields, superfluid he 3 , quantum-hall fluids, and recently in the context of chiral active matter. in most of these studies, odd terms in the viscosity obey onsager reciprocal relations. although this is expected in equilibrium systems, it is not obvious that onsager relations hold in

eph receptors (ephs), the largest family of tyrosine kinases, phosphorylate downstream substrates upon binding of ephrin cell surface–associated ligands. in a large cohort of endometriotic lesions from individuals with endometriosis, we found that epha2 and epha4 expressions are increased in endometriotic lesions relative to normal eutopic endometrium. because signaling through ephs is associated with

structure-activity relationship (sar) studies are fundamental to drug and agrochemical development, yet only a few synthetic strategies apply to the nitrogen heteroaromatics frequently encountered in small molecule candidates.1-3 here, we present an alternative approach where we convert pyrimidine-containing compounds various other nitrogen heteroaromatics. transforming pyrmidines into their corre

bacteria that make food using a compound other than chlorophyll could paint other planets in a wide range of colours.

the sumatran orangutan used a plant known to humans for its medicinal qualities.

researchers are developing vaccines and fresh drug approaches to prevent and treat recurring infections without antibiotics.

the body-brain axis is emerging as a principal conductor of organismal physiology. it senses and controls organ function1,2, metabolism3 and nutritional state4-6. here, we show that a peripheral immune insult powerfully activates the body-brain axis to regulate immune responses. we demonstrate that pro- and anti-inflammatory cytokines communicate with distinct populations of vagal neurons to inform

fluid studded with microscopic magnetic particles can be inserted into the body and later retrieved.

during periods of enforced isolation, life satisfaction for older adults took less of a hit in those who were already socially isolated.

abstract. the late taro takahashi (lamont-doherty earth observatory (ldeo), columbia university) and colleagues provided the first near-global monthly air–sea co2 flux climatology in takahashi et al. (1997), based on available surface water partial pressure of co2 measurements. this product has been a benchmark for uptake of co2 in the ocean. several versions have been provided since, with improvements

abstract. between 14 march 2020 and 11 september 2021, meteorological measurement flights were conducted above the german bight in the framework of the project x-wakes. the scope of the measurements was to study the transition of the wind field and atmospheric stability from the coast to the sea, to study the interaction of wind park wakes, and to study the large-scale modification of the marine atmospheric

abstract. understanding and assessing the spatiotemporal patterns in crop-specific phosphorus (p) fertilizer management is crucial for promoting crop yield and mitigating environmental problems. the existing p fertilizer dataset, derived from sales data, depicts an average application rate on total cropland at the county level but overlooks cross-crop variations. conversely, the survey-based dataset

large ensembles of laser-cooled atoms interacting through infinite-range photon-mediated interactions are powerful platforms for quantum simulation and sensing. here we realize momentum-exchange interactions in which pairs of atoms exchange their momentum states by collective emission and absorption of photons from a common cavity mode, a process equivalent to a spin-exchange or xx collective heisenberg

a molecular clock network is crucial for daily physiology and maintaining organismal health. we examined the interactions and importance of intratissue clock networks in muscle tissue maintenance. in arrhythmic mice showing premature aging, we created a basic clock module involving a central and a peripheral (muscle) clock. reconstituting the brain-muscle clock network is sufficient to preserve fundamental

hydrogels are an attractive category of biointerfacing materials with adjustable mechanical properties, diverse biochemical functions, and good ionic conductivity. despite these advantages, their application in electronics has been restricted because of their lack of semiconducting properties, and they have traditionally only served as insulators or conductors. we developed single- and multiple-network
