Body heat as a power source
by Dr. Jekyll in Lunatic Laboratories
Electronics integrated into textiles are gaining in popularity: Systems like smartphone displays in a sleeve or sensors to detect physical performance in athletic wear have already been produced. The main problem with these systems tends to be the lack of a comfortable, equally wearable source of power. Chinese scientists are now aiming to obtain the necessary energy from body heat by introducing a flexible, wearable thermocell based on two different gel electrolytes.

Particle Acceleration and heating by turbulent reconnection by L. Vlahos, T. Pisokas, H. Isliker, V. Tsiolis and A. Anastasiadis
by CESRA in Solar Radio Science
Fermi (1949) introduced a fundamental stochastic process to solve the problem of particle energization (heating and/or acceleration) in space and astrophysical plasmas. The initial idea of Fermi with randomly moving scatterers (magnetic clouds), was soon replaced with a spectrum of low amplitude (δΒ/Β... Read more »

Higgs or not Higgs, that is the question
by Marco Frasca in The Gauge Connection
LHCP2016 is running yet with further analysis on 2015 data by people at CERN. We all have seen the history unfolding since the epochal event on 4 July 2012 where the announcement of the great discovery happened. Since then, also Kibble passed away. What is still there is our need of a deep understanding of the […]... Read more »

Should Biologists be Guided by Beauty?
by Jalees Rehman in The Next Regeneration
One key characteristic of a beautiful scientific theory is the simplicity of the underlying concepts. According to Weinberg, Einstein's theory of gravitation is described in fourteen equations whereas Newton's theory can be expressed in three. Despite the appearance of greater complexity in Einstein's theory, Weinberg finds it more beautiful than Newton's theory because the Einsteinian approach rests on one elegant central principle – the equivalence of gravitation and ........

Can Pollen Be Used to Make Batteries?
by Jenny Ludmer in Rooster's Report
We all know pollen can terrorize your eyes and nose and make you miserable, but now scientists think it could do something pretty amazing: store energy. Yes, that’s right. By precisely processing the irritating stuff, pollen’s unique structures appear to be perfectly suited to store energy in batteries. And that’s nothing to sneeze at.... Read more »

Quantum gravity

News from CERN
by Marco Frasca in The Gauge Connection
Two days ago, CERN presented their new results at 13 TeV to the World. Of course, collected data so far are not enough for conclusive results but the these are exciting anyway. The reason is that both the collaborations, CMS and ATLAS, see a bump at around 750 GeV in the decay. Summing up the results […]... Read more »

Salamanders Facing Preventable Death
by Jenny Ludmer in Rooster's Report
A deadly fungus is poised to enter North America, threatening to decimate salamander populations, as it has done in Europe. Remarkably, we know its coming and everyone is on board to prevent this calamity — pet industry and owners, animal advocates, conservationists, and policymakers — and yet, one crucial piece is missing: Government. And that begs the question: will we act before it’s too late?... Read more »

Breaking the Size Barrier – Giant Bacteria, part 1
by Mark Lasbury in As Many Exceptions As Rules
The rules of biology say that a bacterium must be small because it doesn’t have dedicated systems for moving molecules around inside the cell and diffusion can only move them so far, so fast. Well, here’s a bacterium that breaks the rule – it’s as big as 3 million other bacteria lumped together! To live this way, this bacterium stores sulfur and nitrogen in amounts that would be enough to kill your cells – everybody has their own rules.... Read more »

Fuels and fungi: A love story
by Rosin Cerate in Rosin Cerate
Fuels and fungi have a long-standing and intricate relationship. Before we get into the juicy details, let's examine the players.Traditionally speaking, a fuel is any organic substance (e.g. wood, coal, and oil) containing lots of stored chemical energy within the bonds holding its atoms together. This energy can be released via combustion, which we harness to move cars forward and generate electricity.Fungi are a huge group of organisms largely describable in terms of what they lack: locomotion........
