(Press-News.org) There are many open questions that the Standard Model cannot answer. One of them is the smallness of the Higgs expectation value vh compared with the Planck scale. In their latest work, Dr Yuta Hamada, Dr Hikaru Kawai and Dr Kiyoharu Kawana at Kyoto University, consider the radiation S of the universe at the late stage as a function of vh, and they show that S reaches its maximum around the observed value vh = 246 GeV.
"If we demand that S should be maximized, this conclusion can be the explanation to the above question. The main contribution to S comes from the decay of baryons. We assume that baryons are produced at the early universe by the Sphaleron process. Because some of baryons exist as atomic nuclei, we must consider the effect caused by the binding energy of atomic nuclei and the possibility that a pion produced by the decay of a nucleon in a helium nucleus is scattered by the remaining nucleons and loses its energy", says Dr Kawana.
The figure above shows the result in which case the current quark masses, the gauge couplings, and the Higgs self-coupling are fixed. ε is the dimensionless parameter that represents the decrease of the radiation due to the pion scattering, and τp (τHe ) is the life time of a proton (Helium nucleus). One can see that S becomes maximum around vh = 246 GeV. This conclusion may be one of the evidences of the Big Fix that the parameters in the Standard Model are naturally fixed so that the radiation of the universe becomes maximum.

Master regulator of key cancer gene found, offers new drug target
2014-06-25
MINNEAPOLIS/ST. PAUL (June 23, 2014) – A key cancer-causing gene, responsible for up to 20 percent of cancers, may have a weak spot in its armor, according to new research from the Masonic Cancer Center, University of Minnesota.
The partnership of MYC, a gene long linked to cancer, and a non-coding RNA, PVT1, could be the key to understanding how MYC fuels cancer cells. The research is published in the latest issue of the journal Nature.
"We knew MYC amplifications cause cancer. But we also know that MYC does not amplify alone. It often pairs with adjacent chromosomal ...
Brewing yeasts reveal secrets of chromosomal warfare and dysfunction
2014-06-25
SEATTLE –Using two yeasts that have been used to brew tea and beer for centuries, researchers at Fred Hutchinson Cancer Research Center have revealed how reproductive barriers might rapidly arise to create species boundaries. Schizosaccharomyces pombe has been used to brew beer in Africa, whereas its close relative S. kombucha is a component of kombucha tea commonly found in health-food stores.
A team of researchers led by Dr. Sarah Zanders of the Basic Sciences Division at Fred Hutch, has uncovered why hybrids between these yeasts (commonly referred to as fission yeasts) ...
3-D computer model may help refine target for deep brain stimulation therapy for dystonia
2014-06-25
LOS ANGELES (June 24, 2014) – Although deep brain stimulation can be an effective therapy for dystonia – a potentially crippling movement disorder – the treatment isn't always effective, or benefits may not be immediate. Precise placement of DBS electrodes is one of several factors that can affect results, but few studies have attempted to identify the "sweet spot," where electrode placement yields the best results.
Researchers led by investigators at Cedars-Sinai, using a complex set of data from records and imaging scans of patients who have undergone successful DBS ...
First comprehensive pediatric concussion guidelines, available now
2014-06-25
Ottawa/Toronto, CANADA – June 25, 2014 – Pediatric emergency medicine researchers at the Children's Hospital of Eastern Ontario (CHEO) together with the Ontario Neurotrauma Foundation (ONF) today launch the first comprehensive pediatric concussion guidelines.
"There have been recommendations and policies on concussion available in the past, but they tend to have focused on sports-related injury and not on children and youth," said Dr. Roger Zemek, project leader, scientist at CHEO, and Assistant Professor of Pediatrics and Emergency Medicine at the University of Ottawa. ...
Researchers treat incarceration as a disease epidemic, discover small changes help
2014-06-25
The incarceration rate has nearly quadrupled since the U.S. declared a war on drugs, researchers say. Along with that, racial disparities abound. Incarceration rates for black Americans are more than six times higher than those for white Americans, according to the U.S. Bureau of Justice Statistics.
To explain these growing racial disparities, researchers at Virginia Tech are using the same modeling techniques used for infectious disease outbreaks to take on the mass incarceration problem.
By treating incarceration as an infectious disease, the scientists demonstrated ...
Resolving apparent inconsistencies in optimality principles for flow processes in geosystems
2014-06-25
Optimality principles have been used, in a holistic approach, to describe flow processes in several important geosystems. Optimality principles refer to the state of a physical system that is controlled by an optimal condition subject to physical and/or resource constraints.
While significant successes have been achieved in applying them, some principles appear to contradict each other.
For example, scientists have found that the formation of channel networks in a river basin follows the minimization of energy expenditure (MEE) rate, while the Earth-atmosphere system ...
Net energy analysis should become a standard policy tool, Stanford scientists say
2014-06-25
Policymakers should conduct "net energy analyses" when evaluating the long-term sustainability of energy technologies, according to new Stanford University research.
Net energy analysis provides a quantitative way to compare the amount of energy a technology produces over its lifetime with the energy required to build and maintain it. The technique can complement conventional energy planning, which often focuses on minimizing the financial cost of energy production, say Stanford researchers.
"The clearest answer to 'why is net energy important?' is that net energy, ...
Animal testing methods for endocrine disruptors should change, team argues
2014-06-25
AMHERST, Mass. – Challenging risk assessment methods used for decades by toxicologists, a new review of the literature led by environmental health scientist Laura Vandenberg at the University of Massachusetts Amherst suggests that oral gavage, the most widely accepted method of dosing lab animals to test chemical toxicity, does not accurately mimic how humans are exposed to chemicals in everyday life.
Oral gavage refers to the way researchers give chemicals to animals by putting a tube down their throats to deliver substances directly to the stomach. It has been used ...
New research shows link unlikely between insomnia symptoms and high blood pressure
2014-06-25
TORONTO, June 25, 2014–There's good news for the 30 per cent or more of adults who suffer from insomnia--difficulty falling asleep, waking up for prolonged periods during the night or unwanted early morning awakenings.
New research from St. Michael's Hospital has found that insomnia does not put them at increased risk of developing high blood pressure.
Dr. Nicholas Vozoris, a respirologist at St. Michael's, said there is growing concern among patients and health care providers about the potential medical consequences of insomnia, especially on the cardiovascular system.
If ...
Incentives as effective as penalties for slowing Amazon deforestation
2014-06-25
The rate of deforestation in the Brazilian Amazon has declined.
An international team of scientists, including one from Virginia Tech, reviewed published research about policy interventions and commodity market effects, and determined that positive incentives for farmers, counties, and states can do as much to preserve forests as public policies that call for penalties.
"The challenge now is to build upon this progress," the team reports in an article in the June 6 issue of Science. "Some immediate and simple positive incentives for responsible, low-deforestation farmers ...
