How many protozoa are in the water we drink?

EurekAlert! Biology - Mon, 2017-06-26 21:00
(FECYT - Spanish Foundation for Science and Technology) Researchers from the University of Zaragoza (Spain) have analyzed drinking water and detected oocysts of Cryptosporidium and cysts of Giardia, two protozoa that cause outbreaks of diarrhea in humans. The levels detected are very low and do not represent a health risk; however, according to the study, the ubiquity of these parasites and the inefficiency of conventional water treatment in reducing them may present a public health issue.

As climate stirs Arctic sea ice faster, pollution tags along

EurekAlert! Biology - Mon, 2017-06-26 21:00
(The Earth Institute at Columbia University) A warming climate is not just melting the Arctic's sea ice; it is stirring the remaining ice faster, increasing the odds that ice-rafted pollution will foul a neighboring country's waters, says a new study.

An Israeli innovation feeds the world with more fish protein

EurekAlert! Biology - Mon, 2017-06-26 21:00
(The Hebrew University of Jerusalem) A new way to grow larger fish and feed the expanding world population has earned a Hebrew University aquaculture expert a 2017 Kaye Innovation Award. Young tilapia fed molecules developed by Prof. Berta Levavi-Sivan gained 25 percent more weight versus fish that did not receive the supplement.

The dust storm microbiome

EurekAlert! Biology - Mon, 2017-06-26 21:00
(Weizmann Institute of Science) The airborne dust carried in sand storms affects the health of people and ecosystems alike. New research at the Weizmann Institute of Science suggests that part of the effect might not be in the particles of dust but rather in bacteria that cling to them, traveling many kilometers in the air with the storms.

3-D-printed jars in ball-milling experiments

EurekAlert! Biology - Mon, 2017-06-26 21:00
(International Union of Crystallography) Mechanochemistry is a widespread synthesis technique in all areas of chemistry. Various materials have been synthesized by this technique when the classical wet chemistry route is not satisfactory. Characterization of the reaction mixture is however much less accessible than in solutions.

Pre-synaptic cadherin/catenin complexes stablize post-synaptic spines in vivo

EurekAlert! Biology - Mon, 2017-06-26 21:00
(Chinese Academy of Sciences Headquarters) A recent study conducted by Dr. YU Xiang's lab at the Institute of Neuroscience of Chinese Academy of Sciences uncovered an asymmetric role for the symmetric cadherin/catenin cell adhesion complexes in functional synapse formation in the neocortex. Pre-synaptic β-catenin is predominant during the formation and mediates dendritic spine stabilization through N-cadherin-dependent anterograde trans-synaptic signaling. The effect of the cadherin/catenin requires p140Cap, a novel β-catenin interacting partner.
