Det hedder sig, at 'plejer' er død eller bør være det, men sådan er det ikke i sundhedsvæsenet. Her kan gammel, veletableret praksis nogle gange overleve i årevis, selv om dokumentationen måske ikke er så god. Men 'plejer' kan også være afsæt for banebrydende forskning.

Mere ulighed i sundhed, tak
Afdelingsledelserne sidder i det daglige krydspres fra patienter, personale, forvaltninger og politikere. Men når opgaverne er flere end ressourcerne, bør de også have retten og pligten til at gøre det, der gavner patienterne mest.

Vi må godt være stolte
I landet, hvor janteloven er opfundet, er vi ikke vant til at løbe rundt og slå os på brystet i begejstring over os selv og vores landsmænd. Men det må være på sin plads at fremhæve, når nogen gør det rigtig, rigtig godt.

Menstrual cycle length pre-menopause may signal heart risk
Near menopause, the menstrual cycle length often changes, becoming longer. The timing of that change could provide clues to a person's risk of heart disease, researchers say. A new study, published in the journal Menopause , characterizes cycle-length changes over the menopause transition and found that women whose cycle increased in length two years before their final menstrual period had better

Scientists discover large rift in the Arctic's last bastion of thick sea ice
In May 2020, a hole a little smaller than the state of Rhode Island opened up for two weeks in the Last Ice Area, a million-square-kilometer patch of sea ice north of Greenland and Ellesmere Island that's expected to be the last refuge of ice in a rapidly warming Arctic. The polynya is the first one that has been identified in this part of the Last Ice Area.

Candidate Suggests Lowering Sea Levels by Taking "All the Boats Out of the Water"
Eureka! Scott Pio, a Republican candidate for Virginia's state legislature who wants to ban abortions and eradicate gun control regulations, may have come up with a solution for climate change that's so brilliant that the rest of us literally can't understand it. What if, Pio speculated on Twitter, we simply got rid of all the boats? "I'm curious," Pio wrote in a since-deleted tweet that was grac

Laser treatment could significantly improve glaucoma care in Africa, potentially at no extra cost
Laser treatment has the potential to transform the management of glaucoma in Africa, and to prevent more people from going irreversibly blind, particularly in regions with high disease prevalence and incidence, suggests new research. Conducted in Tanzania, the research is the first randomised controlled trial exploring the use of the laser treatment, Selective Laser Trabeculoplasty (SLT), for pati

How bacteria create a piggy bank for the lean times
Bacteria can store extra resources for the lean times. It's a bit like keeping a piggy bank or carrying a backup battery pack. One important reserve is known as cyanophycin granules, which were first noticed by an Italian scientist about 150 years ago. He saw big, dark splotches in the cells of the blue-green algae (cyanobacteria) he was studying without understanding either what they were or thei

Cadmium hijacks the high zinc response by binding and activating the HIZR-1 nuclear receptor [Genetics]
Cadmium is an environmental pollutant and significant health hazard that is similar to the physiological metal zinc. In Caenorhabditis elegans, high zinc homeostasis is regulated by the high zinc activated nuclear receptor (HIZR-1) transcription factor. To define relationships between the responses to high zinc and cadmium, we analyzed transcription. Many…

Timing outweighs magnitude of rainfall in shaping population dynamics of a small mammal species in steppe grassland [Population Biology]
Climate change–induced shifts in species phenology differ widely across trophic levels, which may lead to consumer–resource mismatches with cascading population and ecosystem consequences. Here, we examined the effects of different rainfall patterns (i.e., timing and amount) on the phenological asynchrony of population of a generalist herbivore and their food sources…

Genome evolution of the psammophyte Pugionium for desert adaptation and further speciation [Evolution]
Deserts exert strong selection pressures on plants, but the underlying genomic drivers of ecological adaptation and subsequent speciation remain largely unknown. Here, we generated de novo genome assemblies and conducted population genomic analyses of the psammophytic genus Pugionium (Brassicaceae). Our results indicated that this bispecific genus had undergone an allopolyploid…

Neogene continental denudation and the beryllium conundrum [Earth, Atmospheric, and Planetary Sciences]
Reconstructing Cenozoic history of continental silicate weathering is crucial for understanding Earth's carbon cycle and greenhouse history. The question of whether continental silicate weathering increased during the late Cenozoic, setting the stage for glacial cycles, has remained controversial for decades. Whereas numerous independent proxies of weathering in ocean sediments (e.g.,…

Stiffness of targeted layer-by-layer nanoparticles impacts elimination half-life, tumor accumulation, and tumor penetration [Applied Biological Sciences]
Nanoparticle (NP) stiffness has been shown to significantly impact circulation time and biodistribution in anticancer drug delivery. In particular, the relationship between particle stiffness and tumor accumulation and penetration in vivo is an important phenomenon to consider in optimizing NP-mediated tumor delivery. Layer-by-layer (LbL) NPs represent a promising class of…

Spatial social dilemmas promote diversity [Social Sciences]
Cooperative investments in social dilemmas can spontaneously diversify into stably coexisting high and low contributors in well-mixed populations. Here we extend the analysis to emerging diversity in (spatially) structured populations. Using pair approximation, we derive analytical expressions for the invasion fitness of rare mutants in structured populations, which then yields…

Low-bias ncRNA libraries using ordered two-template relay: Serial template jumping by a modified retroelement reverse transcriptase [Biochemistry]
Selfish, non-long terminal repeat (non-LTR) retroelements and mobile group II introns encode reverse transcriptases (RTs) that can initiate DNA synthesis without substantial base pairing of primer and template. Biochemical characterization of these enzymes has been limited by recombinant expression challenges, hampering understanding of their properties and the possible exploitation of…

Prediction of unconventional magnetism in doped FeSb2 [Physics]
It is commonly believed that the energy bands of typical collinear antiferromagnets (AFs), which have zero net magnetization, are Kramers spin-degenerate. Kramers nondegeneracy is usually associated with a global time-reversal symmetry breaking (e.g., via ferromagnetism) or with a combination of spin–orbit interaction and broken spatial inversion symmetry. Recently, another type…

Inherent hepatocytic heterogeneity determines expression and retention of edited F9 alleles post-AAV/CRISPR infusion [Medical Sciences]
Infusing CRISPR/donor-loaded adeno-associated viral vectors (AAV/CRISPR) could enable in vivo hepatic gene editing to remedy hemophilia B (HB) with inherited deficiency of clotting factor IX (FIX). Yet, current regimens focus on correcting HB with simple mutations in the coding region of the F9, overlooking those carrying complicated mutations involving the…

In neurodegenerative diseases, brain immune cells have a 'ravenous appetite' for sugar
At the beginning of neurodegenerative disease, the immune cells of the brain — the 'microglia' — take up glucose, a sugar molecule, to a much greater extent than hitherto assumed. These results are of great significance for the interpretation of brain scans depicting the distribution of glucose in the brain. Furthermore, such image-based data could potentially serve as a biomarker to non-invasiv
