Yang-Mills theory paper gets published!

by Marco Frasca in The Gauge Connection

Exact solutions of quantum field theories are very rare and, normally, refer to toy models and pathological cases. Quite recently, I put on arxiv a pair of papers presenting exact solutions both of the Higgs sector of the Standard Model and the Yang-Mills theory made just of gluons. The former appeared a few month ago […]... Read more »

Climate change, the long view

by gdw in FictionalFieldwork

Now and forever, or at least for a very long time By 2050, sea levels will have risen this much. If we don’t act, average global temperature will rise x degrees by 2100. These are the things we all hear in the discussion concerning climate change and its consequences. But beyond the turn of the […]... Read more »

Forgetting Earth, forgetting Mars: Dementia, pollution, and space travel

by gdw in FictionalFieldwork

Forgetting Earth Dementia. Few words inspire greater fear in those of us who value (quasi-?) independent thought. The term ‘dementia’ encompasses various brain disorders that all share some scary traits: general decline in cognitive function, decreased ability to speak, and in later stages, being unable to take care of oneself. Unfortunately, as human lifespan increases […]... Read more »

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

by Marco Frasca in The Gauge Connection

Quantum gravity appears today as the Holy Grail of physics. This is so far detached from any possible experimental result but with a lot of attentions from truly remarkable people anyway.

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 »

Will the Paris Climate Talks Matter?

by Jenny Ludmer in Rooster's Report

Today, over 190 countries are convening in Paris with one ambitious goal: To reach an agreement for the global reduction of CO2 emissions. Perhaps you’re wondering if these talks even matter. After all, prior meetings have had little impact. (Kyoto or Copenhagen, anyone?) Fortunately, a new study addresses this question, and offers hope.... Read more »
