How old is your tail-wagging bundle of joy in human years? According to the well-known "rule of paw," one dog year is the equivalent of 7 years. Now, in a study published July 2, in the journal Cell Systems, scientists say it's wrong. Dogs are much older than we think, and researchers devised a more accurate formula to calculate a dog's age based on the chemical changes in the DNA as organisms grow old.
COLUMBUS, Ohio - Eating black raspberries might reduce inflammation associated with skin allergies, a new study indicates.
In a study done with mice and published earlier this month in the journal Nutrients, researchers found that a diet high in black raspberries reduced inflammation from contact hypersensitivity - a condition that causes redness and inflammation in the skin.
New technologies capable of sequencing single molecules in fine detail will help scientists better understand the mechanisms of rare nucleotides thought to play an important role in the progression of some diseases.
A review paper, led by a scientist at the University of Birmingham, describes how emerging sequencing technologies will transform our understanding of these molecules, ultimately leading to new drug targets. The paper is published in the journal Trends in Biotechnology.
FINDINGS
A film made of tiny carbon nanotubes (CNT) may be a key material in developing clothing that can heat or cool the wearer on demand. A new North Carolina State University study finds that the CNT film has a combination of thermal, electrical and physical properties that make it an appealing candidate for next-generation smart fabrics.
Astronomers created a stunning new image showing celestial fireworks in star cluster G286.21+0.17.
Most stars in the universe, including our Sun, were born in massive star clusters. These clusters are the building blocks of galaxies, but their formation from dense molecular clouds is still largely a mystery.
The finding follows previous research that found marriage protects against risky alcohol use and moderates genetic influences on alcohol outcomes, but previous studies generally focused on older adult samples.
The dynamics of the SARS-CoV-2 pandemic share "striking similarities" with the twin environmental crises of global heating and species extinction, argue a team of scientists and policy experts from the UK and US.
They say that lessons learned the hard way in containing COVID-19 - the need for early intervention to reduce death and economic damage; the curbing of some aspects of people's lifestyles for the good of all of us - should also be at the heart of averting environmental catastrophe.
Stem cells have been holding great promise for regenerative medicine for years. In the last decade, several studies have shown that this type of cell, which in Spanish is called "mother cell" because of its ability to give rise to a variety of different cell types, can be applied in regenerative medicine for diseases such as muscular and nervous system disorders, among others. Researchers and stem cell pioneers Sir John B. Gurdon and Shinya Yamanaka received the Nobel Prize in Physiology and Medicine in 2012 for this idea.
Researchers from the Shanghai Institute of Organic Chemistry of the Chinese Academy of Sciences recently developed a new platform for rapid chiral analysis, producing chromatogram-like output without the need for separation. The study was published in Cell Reports Physical Science.
Researchers in the ERATO Saitoh Spin Quantum Rectification Project in the JST Strategic Basic Research Programs have elucidated the mechanism of the hydrodynamic power generation using spin currents(1) in micrometer-scale channels, finding that power generation efficiency improves drastically as the size of the flow is made smaller.
Osaka, Japan - Our immune system is supposed to protect us from external microbial invaders, but sometimes it turns its efforts inward, potentially resulting in autoimmune diseases. In a new study, researchers from Osaka University discovered how reversible modifications to our DNA by certain proteins protect us from autoimmune diseases and, conversely, how the absence of these proteins paves the way to autoimmunity.
An estimated 17.3% of people worldwide are at risk of inadequate zinc intake; zinc deficiency is a major human health concern. Increasing Zn concentration in wheat grains is highly important, and management strategies to enhance grain Zn concentration can play an important role in fighting nutrient deficiency.
In a practice known as biofortification, researchers use agronomic practices, plant breeding or biotechnology to increase the macronutrient content of food crops. It is as an effective strategy to increase Zn concentration in wheat grain.
Plants must constantly integrate information on the availability of water and nutrients or about the presence of pathogens to produce fruits and seeds for reproduction, heavily used for human consumption. Given the increasing threat of droughts and the requirements of sustainable plant protection it is important to better understand the molecular mechanisms behind the information processing of plants. So far, different plant hormones were known to trigger molecular signaling pathways that result in developmental transitions like fruit ripening or drought response.
BROOKLYN, N.Y. (July 1, 2020) - Hispanic adults vary widely in their reported trust of health information sources, suggesting that information tailored to specific ethnic subgroups and targeted by age group may be beneficial, according to results of a study by SUNY Downstate Assistant Professor Marlene Camacho-Rivera, MS, MPH, ScD.
