How does the autophagic pathway regulate low-nitrogen tolerance in tomato?
Nitrogen (N) deficiency first affects the N uptake and assimilation systems of plants. Nitrate, the main source of plant N, is absorbed and transported by nitrate transporters. Nitrate can be metabolized directly in the roots after absorption and sto.....»»
Nitrogen-based fertilizers differentially affect protist community composition in paddy field soils, finds study
The soil microbiome has far-reaching significance, particularly for rice production, which can be better explained with a Japanese proverb: "Rice grows with soil fertility, while upland crops depend on fertilization." Therefore, understanding the pad.....»»
Zebrafish usp3 loss found to promote hypoxic tolerance
Oxygen is an essential element for survival. Ocean warming, circadian rhythm, eutrophication, high-density aquaculture, power failures and long-distance live animal transportation can all lead to low oxygen levels in water. This reduction in oxygen c.....»»
Cosmic building blocks of life discovered through the electron microscope
A team of researchers has examined the Winchcombe meteorite and demonstrated the existence in it of nitrogen compounds such as amino acids and heterocyclic hydrocarbons—without applying any chemical treatment and by using a new type of detector des.....»»
Study explores the connection between nitrogen oxides control and SNA, ozone reduction
Sulfate-nitrate-ammonium (SNA) and other atmospheric aerosols play a significant role in influencing both atmospheric and environmental conditions. These aerosols impact climate directly through scattering and absorbing solar radiation, thus influenc.....»»
Snake venom research has broad implications for bite treatment

Chemical synthesis: New strategy for skeletal editing on pyridines
A team from the University of Münster has introduced a strategy for converting carbon–nitrogen atom pairs in a frequently used ring-shaped compound into carbon–carbon atom pairs. The method has potential in the quest for active ingredients for n.....»»
Scientists discover southern Africa"s temps will rise past rhinos" tolerance
Southern Africa contains the vast majority of the world's remaining populations of both black and white rhinoceroses (80% and 92%, respectively). The region's climate is changing rapidly as a result global warming. Traditional conservation efforts ai.....»»
Chromatin modifier-centered pathway points to higher crop yield
A team led by Prof. Song Xianjun from the Institute of Botany of the Chinese Academy of Sciences, while researching a ternary protein complex in rice nuclei that affects grain size, has shown that the transcription factor bZIP23—a protein that regu.....»»
Researchers address formulation, manufacturing challenges in obesity, diabetes drugs
Medications such as Ozempic and Mounjaro are composed of molecules called acylated peptides that are designed to circulate in the body and regulate insulin production. This enables adults with type 2 diabetes to take a weekly injection instead of mon.....»»
