More than half of new drugs entering the German healthcare system have not been shown to add benefit, argue researchers.
New alternate cell growth pathway could lead to better treatments for metastatic cancers
Science Daily - 12 Jul 2019 00:17
A new study has found that the gene, mEAK-7, which they discovered last year, may play a key role in cancer metastasis. By comparing mEAK-7 expression levels in normal and cancer cells, they found that the gene was highl...

Does platelet-rich plasma therapy lower risk of meniscus repair
Science Daily - 11 Jul 2019 23:09
The use of platelet-rich plasma therapy can reduce the risk of a second meniscus failure after operation but does not seem to protect patients who have had surgery to repair an anterior cruciate ligament, according to ne...
Raising eyebrows on neuroinflammation: Study finds novel role for 'skin plumping' molecule
Science Daily - 11 Jul 2019 22:14
Scientists have discovered a novel mechanism and role in the brain for hyaluronic acid -- a clear, gooey substance popularized by cosmetic and skin care products. Hyaluronic acid may be the key in how an immune signal mo...
Are the 'viral' agents of MS, ALS and schizophrenia buried in our genome?
Science Daily - 11 Jul 2019 22:14
What if the missing 'environmental' factor in some of our deadliest neurological diseases were really written in our genome? Researchers explain how viruses ended up in our DNA -- and what puts them in the frame in unsol...
