Human 'molecular map' contributes to the understanding of disease mechanisms

Scientists have created an intricate molecular map of the human body and its complex physiological processes based on the analysis of thousands of molecules in blood, urine and saliva samples from 391 volunteers. The data was integrated to create a powerful, interactive visual web-based tool called Connecting Omics (COmics) that can be used to investigate the complex molecular make-up of humans and discover underlying traits associated with various diseases.

Magnetic field maps of the sun's corona

Astronomers have achieved a major breakthrough in solar physics by successfully producing detailed maps of the Sun's coronal magnetic fields. This milestone promises to enhance our understanding of the Sun's atmosphere and how its changing conditions lead to impacts on Earth's technology-dependent society. The corona, or the Sun's outer atmosphere, greatly influences solar winds and space weather events like solar flares and coronal mass ejections. However, the magnetic forces that... Read more ›

Researchers develop a stretchable, wearable device that lights up an LED using only the warmth of your skin

Researchers have developed a flexible, durable electronic prototype that can harvest energy from body heat and turn it into electricity that can be used to power small electronics, such as batteries, sensors or LEDs. This device is also resilient -- it still functions even after being pierced several times and then stretched 2,000 times. Read more ›

Genes with strong impact on menopause timing also link to cancer risk

The team first looked at variation in data from genetic sequencing of 106,973 post-menopausal female participants in the UK Biobank study. Researchers focused on rare types of genetic changes which cause a loss of the protein, and investigated their effect on the timing of menopause. The genetic changes studied are all rare in the population, however their influence on menopause is five times greater than the impact of any previously... Read more ›
