Universal Blood Test For Cancer Discovered?

Science2.0 - July 28, 2014 - 4:00pm

Researchers from the University of Bradford say they have devised a simple blood test that will enable doctors to rule out cancer in patients presenting with certain symptoms, saving time and preventing costly and unnecessary invasive procedures such as colonoscopies and biopsies being carried out. Alternatively, it could be a useful aid for investigating patients who are suspected of having a cancer that is currently hard to diagnose. 

Early results have shown the method gives a high degree of accuracy diagnosing cancer and pre-cancerous conditions from the blood of patients with melanoma, colon cancer and lung cancer.

1 In 3,000 Blood Donors In England Has Hepatitis E

Science2.0 - July 28, 2014 - 3:36pm

The first systematic analysis of hepatitis E virus (HEV) transmission by blood components indicates that about 1 in 3,000 donors in England have HEV in their plasma. The findings suggest that around 1,200 HEV-containing blood components (eg, red cells, platelets, and fresh frozen plasma) are likely to be transfused every year in England.

Mutations: Male Fertility Is From Mars, Female Fertility Is From Venus

Science2.0 - July 28, 2014 - 3:20pm

About 15% of adults suffer from fertility problems, primarily due to genetic factors.

This is something of an evolutionary paradox; wouldn't natural selection have caused people with infertility to not reproduce?Various theories explain the survival of harmful mutations: A gene that today causes obesity, for example may have once granted an evolutionary advantage; or a disease-causing gene may persist because it is passed on in a small, relatively isolated population.

More On The Alleged WW Excess From The LHC

Science2.0 - July 28, 2014 - 9:02am

This is just a short update on the saga of the anomalous excess of W-boson-pair production that the ATLAS and CMS collaborations have reported in their 7-TeV and 8-TeV proton-proton collision data. A small bit of information which I was unaware of, and which can be added to the picture.

Science 2.0: Google Web Mining Can Help Neuroscientists Analyze Big Data

General - July 27, 2014 - 9:00pm

Facebook, Google and just about everyone except Science 2.0 use global distributed computers to mine your web history and learn everything about you to generate revenue. Big data is being led by marketing, like many things are, but early adopters who make money at things create tools that everyone can then use, and that will be a big help for Science 2.0

New technologies for monitoring brain activity are generating unprecedented quantities of information. If it can ever be interpreted, that data may hold new insights into how the brain works. To help make sense of cranial Big Data, neuroscientists can now use Thunder, a library of tools developed at the Howard Hughes Medical Institute's Janelia Research Campus.

6 New Genetic Risk Factors For Parkinson's Disease Found

Science2.0 - July 27, 2014 - 8:18pm

Using data from over 18,000 patients, scientists have identified more than two dozen genetic risk factors involved in Parkinson's disease, including six that had not been previously reported. 

Affecting millions of people worldwide, Parkinson's disease is a degenerative disorder that causes movement problems, including trembling of the hands, arms, or legs, stiffness of limbs and trunk, slowed movements and problems with posture. Over time, patients may have difficulty walking, talking, or completing other simple tasks. Although nine genes have been shown to cause rare forms of Parkinson's disease, scientists continue to search for genetic risk factors to provide a complete genetic picture of the disorder.

Epigenetics Implicated In Mouse Cancer

Science2.0 - July 27, 2014 - 7:00pm

If you go by stories of epigenetics and the microbiome, we are on the verge of curing all disease. There hasn't been this much hype since human embryonic stem cells and the human genome project were going to cure all ailments in 2000.

But behind the hype there is some science, it is just figuring out what is epigenetics, what is genetics and then what is instead epidemiological matching of correlation and causation that is the struggle.

How To Distinguish Psoriasis From Eczema

Science2.0 - July 27, 2014 - 5:30pm
In some patients, the chronic inflammatory skin diseases psoriasis and eczema are so similar that dermatologists have had to examine tissue samples but a team of researchers at the Helmholtz Zentrum München and the Technical University of Munich (TUM) have now analyzed the molecular processes that occur in both diseases and discovered crucial differences.

This has enabled them to develop a diagnostic procedure which in practice enables psoriasis and eczema to be reliably differentiated from one another on the basis of only two genes.
