Overlooked peptide reveals clues to causes of Alzheimer's disease
Researchers at the RIKEN Brain Science Institute and their collaborators have shed light on the function of a little-studied amyloid peptide in promoting Alzheimer's disease (AD).

Biomarker MIA shows presence of neurofibromas
Neurofibromatosis (NF1) is a genetic condition which affects one in every 3,000 people.

Genetic variant linked to development of liver cancer in hepatitis C virus carriers
A genome-wide study by researchers at the RIKEN Center for Genomic Medicine, Hiroshima University Hospital and Sapporo-Kosei General Hospital has identified a genetic variant associated with the development of liver cancer in chronic hepatitis C virus carriers.

Specialized seeds can really float your boat
A new artificial surface inspired by floating seeds could provide an alternative to the toxic paints currently used to prevent fouling on ship hulls.

Researchers decipher protein structure of key molecule in DNA transcription system
Scientists have deciphered the structure of an essential part of Mediator, a complex molecular machine that plays a vital role in regulating the transcription of DNA.

Getting aid to where it is needed
In the early 2000s, the international aid community started to fund health programs through Global Health Initiatives (GHIs) which provide aid and support for tackling infectious diseases, and for implementing immunization programs against childhood diseases.

Warming ocean layers will undermine polar ice sheets
Warming of the ocean's subsurface layers will melt underwater portions of the Greenland and Antarctic ice sheets faster than previously thought, according to new University of Arizona-led research.

UBC 'megapixel' DNA replication technology promises faster, more precise diagnostics
UBC researchers have developed a DNA measurement platform that sets dramatic new performance standards in the sensitivity and accuracy of sample screening.

Important step in the next generation of computing
Scientists have taken one step closer to the next generation of computers.

Could ovarian stimulation cause an increase in chromosome copy number abnormalities?
Ovarian stimulation undertaken by women of advanced maternal age receiving fertility treatment may be disrupting the normal pattern of meiosis -- a critical process of chromosome duplication followed by two specialized cell divisions in the production of oocytes and sperm - and leading to abnormalities of chromosome copy numbers that result in IVF failure, pregnancy loss or, more rarely, the birth of affected children with conditions such as Down's syndrome, which is caused by the inheritance of three copies of chromosome 21.

Biofuels from the sea
The use of kelp as a biofuel could provide an important alternative to terrestrial grown biofuels; however the suitability of its chemical composition varies on a seasonal basis.
