Sisters improve chances of reproduction in Asian elephants
Researchers at the University of Turku found that the presence of a maternal sister was positively and significantly associated with annual female reproduction in a population of working elephants in Myanmar. In addition, an age-specific effect was found: young females were more sensitive to the presence of sisters and even more likely to reproduce when living near a sister.

Left eye? Right eye? American robins have preference when looking at decoy eggs
Just as humans are usually left- or right-handed, other species sometimes prefer one appendage, or eye, over the other. A new study reveals that American robins that preferentially use one eye significantly more than the other when looking at their own clutch of eggs are also more likely to detect, and reject, a foreign egg placed in their nest by another bird species — or by a devious scientist.

100 days, 100 nights: Sensor network reveals telltale patterns in neighborhood air quality
Black carbon — a contributor to global warming and a pollutant of concern to residents in urban areas — can be difficult to track. To address this problem, researchers generated a technology that didn't exist. With more than 100 custom-built sensors installed for 100 days, the team created the largest black carbon monitoring network to be deployed in a single city, setting a foundation for the f

Monsoon rains have become more intense in the southwest in recent decades
Monsoon rain storms have become more intense in the southwestern United States in recent decades, according to a recent study. Monsoon rains — highly localized bursts of rain — have become stronger since the 1970s, meaning the same amount of rain falls in a shorter amount of time — by 6 to 11 percent. In addition, the number of rainfall events per year increased on average 15 percent during the

Study: There's Way More Water on the Moon Than We Thought
Moon Water A team of researchers at the University of California says that there could be way more ice water on the surface of the Moon than previously believed — and that could be a huge deal for future missions to the Moon. By comparing shaded areas that are protected from the Sun on the surface of Mercury with similar shadowed craters on the Moon, they concluded that ice deposits, sometimes se

Loss of gut barrier integrity triggers activation of islet-reactive T cells and autoimmune diabetes [Immunology and Inflammation]
Low-grade intestinal inflammation and alterations of gut barrier integrity are found in patients affected by extraintestinal autoimmune diseases such as type 1 diabetes (T1D), but a direct causal link between enteropathy and triggering of autoimmunity is yet to be established. Here, we found that onset of autoimmunity in preclinical models…

The orphan nuclear receptor NR4A3 controls the differentiation of monocyte-derived dendritic cells following microbial stimulation [Immunology and Inflammation]
In response to microbial stimulation, monocytes can differentiate into macrophages or monocyte-derived dendritic cells (MoDCs) but the molecular requirements guiding these possible fates are poorly understood. In addition, the physiological importance of MoDCs in the host cellular and immune responses to microbes remains elusive. Here, we demonstrate that the nuclear…

Adaptation by naive CD4+ T cells to self-antigen-dependent TCR signaling induces functional heterogeneity and tolerance [Immunology and Inflammation]
Naïve CD4+ T cells experience weak T cell receptor (TCR) signals induced by self-peptides presented by MHC II.

Mice deficient in CASP8 and RIPK3 (Casp8−/−Ripk3−/−) mount enhanced…

YIPF6 controls sorting of FGF21 into COPII vesicles and promotes obesity [Medical Sciences]
Fibroblast growth factor 21 (FGF21) is an endocrine hormone that regulates glucose, lipid, and energy homeostasis. While gene expression of FGF21 is regulated by the nuclear hormone receptor peroxisome proliferator-activated receptor alpha in the fasted state, little is known about the regulation of trafficking and secretion of FGF21. We show…

pHERV-W envelope protein fuels microglial cell-dependent damage of myelinated axons in multiple sclerosis [Neuroscience]
Axonal degeneration is central to clinical disability and disease progression in multiple sclerosis (MS).

However, the exact underlying mechanisms have still not been clarified. We have previously demonstrated that human endogenous…

Moreover, numerous proteins interact with αSN species, influencing its toxicity in the brain. In the present study, we extended analyses of αSN-interacting proteins to cerebrospinal fluid (CSF). Using coimmunoprecipitation, followed by mass spectrometry,…

Trpc5 deficiency causes hypoprolactinemia and altered function of oscillatory dopamine neurons in the arcuate nucleus [Neuroscience]
Dopamine neurons of the hypothalamic arcuate nucleus (ARC) tonically inhibit the release of the protein hormone prolactin from lactotropic cells in the anterior pituitary gland and thus play a central role in prolactin homeostasis of the body. Prolactin, in turn, orchestrates numerous important biological functions such as maternal behavior, reproduction,…
