Prof. Maria-Elena Torres-Padilla, Director of the Institute of Epigenetics and Stem Cells at Helmholtz Zentrum München and her colleague Dr. Adam Burton are doing pioneering work in this field.
Why would we want to reprogram cells?
Young children from dog-owning households have better social and emotional wellbeing than children from households who do not own a dog, suggests research published in the journal Pediatric Research.
Teenagers who prefer to stay up late and wake later in the morning are more likely to suffer with asthma and allergies compared to those who sleep and wake earlier, according to a study published in ERJ Open Research. [1]
Asthma symptoms are known to be strongly linked to the body's internal clock, but this is the first study to look at how individual sleep preferences influence asthma risk in teenagers.
The New Siberian Islands were the birthplace of the MOSAiC floe: the sea ice in which the research vessel Polarstern is now drifting through the Arctic was formed off the coast of the archipelago, which separates the East Siberian Sea and the Laptev Sea to the north of Siberia, in December 2018. Sediments, and even small pebbles and bivalves, were incorporated into the ice during the freezing process, which the on-going melting process has brought to light on the surface of the MOSAiC floe.
Research explains how a unicellular marine organism generates light as a response to mechanical stimulation, lighting up breaking waves at night.
When we think of engineering in nature, we tend to think of beavers -- the tree-felling, dam-building rodents whose machinations can shape the landscape by creating lakes and changing the path of rivers. But beavers are far from the only organisms to reshape their environment. A squirrel who inadvertently plants oak trees is also an "ecosystem engineer" -- roughly speaking, any organism whose impact on the environment outlasts its own lifetime.
Study of more than 400 Syrian refugee children in Lebanon identified significant development and learning difficulties when children are above the regular age for their grade.
NYU researchers drew insights into potential impacts as children around the world return to school following COVID-19.
Researchers at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, are advancing gas membrane materials to expand practical technology options for reducing industrial carbon emissions.
Results published in Chem demonstrate a fabrication method for membrane materials that can overcome current bottlenecks in selectivity and permeability, key variables that drive carbon-capturing performance in real environments.
WOODS HOLE, Mass. - The offspring of older mothers don't fare as well as those of younger mothers, in humans and many other species. They aren't as healthy, or they don't live as long, or they have fewer offspring themselves. A longstanding puzzle is why evolution would maintain this maternal effect in so many species, since these late-born offspring are less fit to survive and reproduce.
Use marijuana while pregnant, and your child is more likely to suffer sleep problems as much as a decade later, according to a new University of Colorado Boulder study of nearly 12,000 youth.
Published in Sleep Health: The Journal of The National Sleep Foundation, the paper is the latest to link prenatal cannabis use to developmental problems in children and the first to suggest it may impact sleep cycles long-term.
Breast cancer patients who are overweight or obese might benefit less from treatment with docetaxel, a common chemotherapy drug, than lean patients. An international team of researchers based this conclusion on a retrospective analysis of data from a large clinical trial. Their study was published in the Journal of Clinical Oncology.
Motile sperm are difficult to collect with a conventional cell sorter because they are vulnerable to physical damage. A research collaboration between Kumamoto and Kyoto Universities in Japan has developed a technique that uses a cell sorter with microfluidic chip technology to reduce cell damage and improve in vitro fertilization (IVF) rates.
The vitality of preterm infants should be assessed with an Apgar score, a tool used to measure the health of newborns immediately after birth. That is the conclusion by researchers at Karolinska Institutet in Sweden who in a large observational study examined the value of Apgar scores for preterm infants. The findings are published in the New England Journal of Medicine.
Almost all land plants employ an army of molecular editors who correct errors in their genetic information. Together with colleagues from Hanover, Ulm and Kyoto (Japan), researchers from the University of Bonn have now transferred one of these proofreaders from the moss Physcomitrium patens (previously known as Physcomitrella patens) into a flowering plant. Surprisingly, it performs its work there as reliably as in the moss itself. The strategy could be suitable for investigating certain functions of the plant energy metabolism in more detail.
MADISON, Wis. -- University of Wisconsin-Madison engineers have made it possible to remotely determine the temperature beneath the surface of certain materials using a new technique they call depth thermography. The method may be useful in applications where traditional temperature probes won't work, like monitoring semiconductor performance or next-generation nuclear reactors.
