Solving a condensation mystery

Posted by in categories: computing, engineering, sustainability

Condensation might ruin a wood coffee table or fog up glasses when entering a warm building on a winter day, but it’s not all inconveniences; the condensation and evaporation cycle has important applications.

Water can be harvested from “thin air,” or separated from salt in desalination plants by way of . Due to the fact condensing take heat with them when they evaporate, it’s also part of the cooling process in the industrial and high-powered computing arenas. Yet when researchers took a look at the newest method of condensation, they saw something strange: When a special type of is covered in a thin layer of oil, condensed water droplets seemed to be randomly flying across the surface at high velocities, merging with larger droplets, in patterns not caused by gravity.

“They’re so far apart, in terms of their own, relative dimensions”—the droplets have a diameter smaller than 50 micrometers—” and yet they’re getting pulled, and moving at really high velocities,” said Patricia Weisensee, assistant professor of mechanical engineering & materials science in the McKelvey School of Engineering at Washington University in St. Louis.

Hubble Space Telescope Snaps ‘In Bloom’ Spiral Galaxy in Space

Posted by in category: space

The Hubble Space Telescope recently spotted a gorgeous “in bloom” spiral galaxy and it shows vibrant star formation pockets that look like red flowers.

The spiral galaxy, which is named NGC 972, was shared by the Hubble Space Telescope on Monday, July 1. NGC 972’s orange-pink glow comes from hydrogen gas reacting to intense light beaming outwards from neighboring newborn stars, said a Hubble Space Telescope press release. These bright patches, which are scattered near various cosmic dust streams, are “blooming” like roses in NGC 972.

First proof-of-concept demonstrates genetic sex selection in mammals

Posted by in categories: biotech/medical, genetics, sex

Certain plants, insects, crustaceans and fish possess the uncanny ability to change the sex of their offspring before they are born. Mammals have never before demonstrated this genetic skill, until now.

A new Tel Aviv University study reveals a genetic system in that enables two animals to mate and produce only females. A similar system based on identical principles would produce only males.

Research for the breakthrough study was led by Prof. Udi Qimron, Dr. Ido Yosef and Dr. Motti Gerlic and conducted by Dr. Liat Edry-Botzer, Rea Globus, Inbar Shlomovitz and Prof. Ariel Munitz, all of the Department of Clinical Microbiology and Immunology at TAU’s Sackler School of Medicine. The research was published on July 1 in EMBO Reports.

Wired Bacteria Form Nature’s Power Grid: ‘We Have an Electric Planet’

Posted by in category: energy

At three o’clock in the afternoon on September 4, 1882, the electrical age began. The Edison Illuminating Company switched on its Pearl Street power plant, and a network of copper wires came alive, delivering current to a few dozen buildings in the surrounding neighborhood.


Electroactive bacteria were running current through “wires” long before humans learned the trick.
