Traditional hydrologic models may misidentify snow as rain, new citizen science data shows
Normally, we think of the freezing point of water as 32°F - but in the world of weather forecasting and hydrologic prediction, that isn't always the case. In the Lake Tahoe region of the Sierra Nevada, the shift from snow to rain during winter storms may actually occur at temperatures closer to 39.5°F, according to new research from the Desert Research Institute (DRI), Lynker Technologies, and citizen scientists from the Tahoe Rain or Snow project.

Fatty tissue accumulated in the neck linked to heart problems, study finds
Researchers from the University of Granada warn that an accumulation of fatty tissue in the neck (both the double chin and the deeper deposits, located between muscles and around the cervical vertebrae) is a predictor of central and overall adiposity, cardiometabolic risk, and a pro-inflammatory profile in sedentary young adults (2021-02-17)

Method for temporal monitoring of microplastic sedimentation
Researchers in Finland have tested the sediment trap method to analyse the annual accumulation rates of microplastics in a body of water, and possible seasonal variation therein.

Electrical spin filtering the key to ultra-fast, energy-efficient spintronics
A new UNSW study is a step towards even-faster, more energy-efficient 'spintronic' technology - an exciting, beyond-CMOS technology. The new study applies 'spin-filtering' to separate spin orientation, allowing generation and detection of spin via electrical (rather than magnetic) means, because electric fields are a lot less energetically costly to generate than magnetic fields.

Tweaking carotenoid genes helps tomatoes bring their a-game
Researchers led by the University of Tsukuba demonstrated that Target-AID gene editing technology can be used to simultaneously introduce single-base changes into multiple genes in tomatoes. Using this technique, the researchers altered three genes associated with carotenoid accumulation, resulting in elevated levels of carotenoids, particularly lycopene, in the resulting tomato lines. This technology will allow tomato breeders to introduce multiple advantageous gene changes into elite commercial cultivars, bypassing lengthy back-crossing steps between generations. (2020-12-01)

Taking out the trash is essential for brain health
Researchers at Tokyo Medical and Dental University (TMDU) have identified a protein called Wipi3 that is essential for cellular waste disposal via the alternative autophagy system. Deletion of Wipi3 in the brains of mice causes growth and motor defects attributed to neuronal accumulation of iron, resulting in neurodegeneration. However, over-expression of another alternative autophagy protein, Dram1, reverses the effects in Wipi3 deficiency, and may represent a novel treatment for neurodegenerative diseases. (2020-11-19)

Research on environmental history: 330-year-old poplar tree tells of its life
Similar to genetic mutations, epigenetic changes, i.e. gene modifications that do not occur on the primary DNA sequence, sometimes arise accidentally in plants and can be transmitted across generations. Using trees as a model, researchers have now shown for the first time that these so-called epimutations accumulate continuously throughout plant development, and that they can be employed as a molecular clock to estimate the age of a tree. (2020-11-18)

Found: a genetic link to molecular events that precede symptoms in Alzheimer's disease
Tufts researchers find a key mutation causing abnormal transport of BACE1, the enzyme responsible for processing the Alzheimer's disease-linked amyloid protein.

Trehalose 6-phosphate promotes seed filling by activating auxin biosynthesis
Plants undergo several developmental transitions during their life cycle. The differentiation of the young embryo from a meristem like structure into a highly specialized storage organ, is believed to be controlled by local connections between sugars and hormonal response systems. By modulating the trehalose 6?phosphate (T6P) content in growing embryos of pea (Pisum sativum), an international research team led by the Leibniz Institute of Plant Genetics and Crop Plant Research (IPK) investigated the role of this signaling sugar during the seed?filling process. (2020-11-05)

ALS and frontotemporal dementia: early diagnosis thanks to an experimental test
A test to diagnose two very serious diseases such as ALS and FTD when the pathologies have not yet appeared: a new methodology succeeds in detecting the protein TDP-43 - the same that accumulates in the brain of patients - even when it is present in minute quantities in the body. Since there are currently no treatments that can interfere with the course of the two diseases, early detection could be of great help to develop useful drugs and understand their dynamics (2020-10-26)

Why do structural differences in α-synuclein aggregates cause different pathologies?
Abnormal α-synuclein aggregation has been implicated in several neurodegenerative diseases and is known to spread in a prion-like manner. There is a relationship between protein aggregate structure (strain) and clinical phenotype in prion diseases, however, whether differences in the strains of α synuclein aggregates account for the different pathologies remained unclear. Researchers in Tokyo Metropolitan Institute of Medical Science (TMIMS) discovered a possible molecular mechanism to account for the different pathologies induced by different α synuclein strains.
