Mast cell (MC)-associated diseases, including allergy/anaphylaxis and neuroinflammatory pain disorders, exhibit a sex bias, with females at increase risk. While much attention has been directed toward adult sex hormones as drivers of sex differences, that female sex bias in MC-associated diseases is evident in prepubertal children, suggesting early-life origins of…
For the first time doctors have shown that measuring changes in 24-hour heart rate can reliably indicate whether or not someone is depressed. In practical terms, this may give clinicians an objective "early warning" of potential depression, as well as a rapid indication whether or not treatment is working, so opening the way to more rapid and responsive treatment.

Fewer than 600 people have been to space in the entire history of humankind, and I want to be one of them. Fights to space are expensive, though, and training to be an astronaut is a grueling endeavor. So I have a different idea: I want to hitch a ride into orbit on the SpaceX Rideshare program. Normally it's used to carry satellites and other cargo into orbit, so my plan would be to buy a used s

Nagoya University bioscientist Michitaka Notaguchi and colleagues in Japan recently found that the tobacco plant Nicotiana promotes adhesion of tissue and can maintain grafts between a broad range of species. They also identified "β-1,4 glucanases" as a key molecule in facilitating tissue adhesion of grafts. Their findings could aid crop production and lessen impact on ecosystems.

A new study suggests that the mass extinction that gave dinosaurs the evolutionary upper hand was caused by oceanic oxygen deprivation. Using ratios of sulfur isotopes, researchers could estimate changes in ocean oxygen levels in ancient seas. The authors suggest a similar mechanism as that which can cause dead zones in oceans today caused a mass extinction. Living on Earth isn't always easy. The
Sphingolipid dysregulation is often associated with insulin resistance, while the enzymes controlling sphingolipid metabolism are emerging as therapeutic targets for improving insulin sensitivity. We report herein that sphingosine kinase 2 (SphK2), a key enzyme in sphingolipid catabolism, plays a critical role in the regulation of hepatic insulin signaling and glucose…
Homeostasis is indispensable to counteract the destabilizing effects of Hebbian plasticity. Although it is commonly assumed that homeostasis modulates synaptic strength, membrane excitability, and firing rates, its role at the neural circuit and network level is unknown. Here, we identify changes in higher-order network properties of freely behaving rodents during…
Proline-rich domains (PRDs) are among the most prevalent signaling modules of eukaryotes but often unexplored by biophysical techniques as their heterologous recombinant expression poses significant difficulties. Using a "divide-and-conquer" approach, we present a detailed investigation of a PRD (166 residues; ∼30% prolines) belonging to a human protein ALIX, a versatile…
We formulate a general method to extend the decomposition of stochastic dynamics developed by Ao et al. [J. Phys. Math.

Biologists studied the migration patterns of steelhead, a subpopulation of rainbow trout that migrates to the Pacific Ocean, where the growing fish hunt and feed until they return to their natal freshwater streams to spawn. Steelhead migration was triggered by the lengthening daylight of spring rather than factors like recent rains.
Researchers have exposed major changes taking place in the insect communities of the Arctic. Their study reveals how climate change is affecting small but important predators of other insects, i.e. parasitoids.
Insect pollination is as important to Arctic plants as it is to plants further south. When flowers abound, the plants have to compete for pollinators. Researchers reveal that higher temperatures cause the flowering periods of different plant species to pile up in time. As a consequence, climate change may affect the competitive relationships of plants.
A new study answers the question of whether or not blood cell telomere length is a suitable proxy for telomere length in other tissues by examining over 20 human tissue types, finding variations and correlations between different tissue types.
Biological sex has a small but ubiquitous influence on gene expression in almost every type of human tissue, reports a new study. These sex differences are observed for genes involved in many functions, including how people respond to medication, how women control blood sugar levels in pregnancy, how the immune system functions, how cancer develops and male pattern baldness. The information could
