Protein defect leaves sperm chasing their tails

A team led by researchers from Osaka University identify a protein required for electrical signal sensing, which, when defective, causes sperm to swim in circles.

How ion adsorption affects biological membranes' functions

In a new study published in EPJ E, Izabela Dobrzy?ska from the University of Bia?ystok, Poland, develops a mathematical model describing the electrical properties of biological membranes when ions such as calcium, barium ...

Structure of electrolyte controls battery performance

The research team at the Department of Electrical and Electronic Information Engineering, Toyohashi University of Technology has reported that adding water into an electrolyte improves the function of vanadium oxide, a positive ...

New study uncovers the interaction of calcium channels

Korean researchers have identified the interactions of the combinants among calcium channel proteins that exist in nerve and heart cells. The result opened a new path of developing treatments for high blood pressure and brain ...

New sensor measures calcium concentrations deep inside tissue

Key processes in the body are controlled by the concentration of calcium in and around cells. A team from the Technical University of Munich (TUM) and the Helmholtz Zentrum München have developed the first sensor molecule ...

Ambush in a petri dish

If green algae of the species Chlamydomonas reinhardtii meet Pseudomonas protegens bacteria, their fate is sealed. The bacteria, measuring only some two micrometres, surround the algae, which are around five times larger, ...

Making spines from sea water

Some sea creatures cover themselves with hard shells and spines, while vertebrates build skeletons out of the same minerals. How do these animals get the calcium they need to build these strong mineral structures? Professors ...

Calcium aids chromosome condensation prior to cell division

Osaka University-led Japanese research reveals role for calcium ions in chromosome condensation during mitosis; high-resolution imaging of living cells reveals compact, globular chromosomes in the presence of calcium that ...
