Biogeochemists make recommendations for tackling 'hidden' phosphorus

As the world tries to mitigate agriculture's effect on the environment, much of the story can be found in the soils, which stores and cycles nutrient elements of carbon, nitrogen, and phosphorus. Biogeochemist are set to find answers, but, the challenge is first being able to accurately measure where phosphorus has accumulated in the Read more ›

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 ›

Breakthrough research sheds light on the hidden effects of stress on sperm

A new study reveals that stress-induced changes in sperm motility occur after a stressful event, rather than during it and improves sperm performance. The discovery is essential in understanding how stress impacts the reproductive process to improve fetal development outcomes. 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 ›

Mirror, mirror, in my tank, who's the biggest fish of all?

Researchers have demonstrated that bluestreak cleaner wrasse (Labroides dimidiatus) checked their body size in a mirror before choosing whether to attack fish that were slightly larger or smaller than themselves, saying it was the first time for a non-human animal to be demonstrated to possess some mental states that are elements of private self-awareness.

Scientists expand the genetic alphabet to create new proteins

It's a dogma taught in every introductory biology class: Proteins are composed of combinations of 20 different amino acids, arranged into diverse sequences like words. But researchers trying to engineer biologic molecules with new functions have long felt limited by those 20 basic building blocks and strived to develop ways of putting new building blocks -- called non-canonical amino acids -- into their proteins. Now, scientists have designed a new... Read more ›

Researchers uncover shared cellular mechanisms across three major dementias

Researchers have for the first time identified degeneration-associated 'molecular markers' -- observable changes in cells and their gene-regulating networks -- that are shared by several forms of dementia that affect different regions of the brain. Critically, the research also identified markers specific to different forms of dementia, and the combined findings represent a potential paradigm shift in the search for causes, treatments and cures.
