Dynamic expression of brain serotonin receptors across the menstrual cycle provides clues about premenstrual dysphoric disorder
A new study explores the interplay between the serotonin system and estradiol in the brain, showing that the central nervous system in patients with premenstrual dysphoric disorder (PMDD) seems to increase serotonin transporter density from the periovulatory phase (when estradiol levels are high) to premenstrual cycle phase (when both estradiol and progesterone are decreasing). The findings have t

Crassulacean Acid Metabolism (CAM) is a water-conserving carbon dioxide (CO2) fixation pathway, and Epiphytes with CAM photosynthesis are widespread in vascular plants.

Six tips for keeping children safe online
If you're a parent of teenagers, you might feel like your kids have the upper hand when it comes to technology. As digital natives, teens intrinsically (or so it seems) understand what platforms, programs, apps, and social media channels to use when—and, unlike many of the adults in their lives, they know how to use them.
Is the middle Cambrian Brooksella a hexactinellid sponge, trace fossil or pseudofossil?
More than 100 years ago, Charles Doolittle Walcott from the Smithsonian Institution was asked to examine strange star-shaped fossils with lobes hailing from the ~ 514-million-year-old Conasauga Formation in Alabama. Walcott described these odd fossils as jellyfish that likely floated in the middle Cambrian seas of what is now the southeastern United States. Little did he know that the Cambrian fos
The war in Ukraine could trigger a land investment rush as happened during the 2008 financial crisis

How birds got their wings
Modern birds capable of flight all have a specialized wing structure called the propatagium without which they could not fly. The evolutionary origin of this structure has remained a mystery, but new research suggests it evolved in nonavian dinosaurs. The finding comes from statistical analyses of arm joints preserved in fossils and helps fill some gaps in knowledge about the origin of bird flight
Could a naturally occurring amino acid lead us to a cure for COVID-19?
After more than two years since its discovery, six million deaths, and half a billion reported cases, there is still no effective cure for COVID-19. Even though vaccines have lowered the impact of outbreaks, patients that contract the disease can only receive supportive care while they wait for their own body to clear the infection.

How Similar Are Humans and Monkeys?
As much as we like to think of ourselves as superior, humans are animals.

Though we've evolved since then, we're still 98.8 percent the same as chimpanzees and bonobos. Humans and monkeys are so much alike that documenting our similarities is much easier than listing ou

Curtin University researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as mollusks and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 percent between 2007 and 2021.
Making engineered cells dance to ultrasound
Let's say you needed to move an individual cell from one place to another. How would you do it? Maybe some special tweezers? A really tiny shovel?
Image: Sun releases strong solar flare
The Sun emitted a strong solar flare, peaking at 3:16 p.m. ET on Feb. 17, 2023. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.
Phonon-driven intra-exciton Rabi oscillations in CsPbBr3 halide perovskites
Nature Communications, Published online: 24 February 2023; doi:10.1038/s41467-023-36654-2 Coupling electromagnetic radiation with matter is promising to tailor optoelectronics properties of functional materials. Here, the authors demonstrate that internal fields induced by coherent lattice motions can be used to control transient excitonic optical response in halide perovskite crystals.
Social complexity, life-history and lineage influence the molecular basis of castes in vespid wasps
Nature Communications, Published online: 24 February 2023; doi:10.1038/s41467-023-36456-6 A key hypothesis for the evolution of division of labour in social insects is that a shared set of genes – a genetic toolkit – regulates reproductive castes across species. Here, the authors analyze brain transcriptomes from nine species of social wasps to identify the factors that shape this toolkit.
Complex-tensor theory of simple smectics
Nature Communications, Published online: 24 February 2023; doi:10.1038/s41467-023-36506-z As lamellar materials, smectics exhibit both liquid and solid characteristics, making them difficult to model at the mesoscale. Paget et al. propose a complex tensor order parameter that reflects the smectic symmetries, capable of describing complex defects including dislocations and disclinations.
Scientists unlock key to drought-resistant wheat plants with longer roots

Återhämtning från bröstcancer – detta spelar roll
En av tio kvinnor får bröstcancer under sin levnad. De flesta överlever. Men den mentala återhämtningen varierar från person till person. En ny avhandling har undersökt den personliga förmågan att hantera krissituationer. Tre omständigheter visade sig vara särskilt viktiga.
