Breastfeeding, even partially alongside formula feeding, changes the chemical makeup—or metabolome—of an infant’s gut in ways that positively influence brain development and may boost test scores years later, suggests new CU Boulder research. “For those who struggle with exclusively breastfeeding, this study suggests your baby can still get significant benefits if you breastfeed as much as you can,” said senior author Tanya Alderete, an assistant professor of integrative physiology at CU Boulder. The study, published Dec. 13 in the journal npj Metabolic Health and Disease, also identifies specific ...

Infertility affects around 48 million couples worldwide and can have various causes. In mammals, including humans, eggs are produced in the ovary. When this process goes wrong, it can lead to female infertility. One example of this is premature ovarian insufficiency, which is characterised by problems with egg production before the age of 40. Up to 3.7% of females experience infertility as a result of this condition, and around 30% of cases are due to genetic variations. Professor Kehkooi Kee, from Tsinghua University, China, who helped ...

EMBARGOED FOR RELEASE UNTIL 4 P.M. ET,WEDNESDAY, DECEMBER 13, 2023 MINNEAPOLIS – People who have very irregular sleep patterns may have a higher risk of dementia than those who have more regular sleep patterns, according to new research published in the December 13, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study does not prove that sleep irregularity causes dementia. It only shows an association. Sleep regularity is how consistent you are at going to sleep and waking up at the same time each day.   “Sleep health recommendations often focus on getting the recommended ...

(MEMPHIS, Tenn. – December 13, 2023) A study from St. Jude Children’s Research Hospital sheds light on the incidence of prediabetes and diabetes in childhood cancer survivors for better prevention and treatment. At a younger age, childhood cancer survivors can experience chronic conditions such as diabetes, typically associated with older individuals. Researchers found survivors have twice the risk of developing prediabetes than the general public, which increases their risk of other life-threatening diseases. In the general population, prediabetes can be modified with lifestyle and other interventions, suggesting the potential to improve ...

Copy and paste.  It’s a simple concept.  You define some text or image on your computer, copy it, and paste it where you want it.  Now, think of that new leather sofa you crave.  Popular augmented reality (AR) apps allow you to cut and paste an image of the sofa into a photo of your living room to see if you like it before buying.  A team of researchers at USC Viterbi’s Thomas Lord Department of Computer Science has now developed a similar technique to copy virtual 3D objects and paste them into real indoor scenes. This creates an overall ...

Consumers grapple with confusion over food-date labels The use of food-date labels such as “use-by” and “best if used by” causes consumer confusion that results in many Americans discarding food that is safe to eat or donate, according to the November 2023 Consumer Food Insights Report. The survey-based report out of Purdue University’s Center for Food Demand Analysis and Sustainability assesses food spending, consumer satisfaction and values, support of agricultural ...

(Santa Barbara, Calif.) — About half of an average American building’s energy consumption is spent on heating and cooling. That’s a lot of money spent, fossil fuel burned and strain on an aging energy infrastructure during times of severe temperatures. It’s also a problem UC Santa Barbara researchers Charlie Xiao, Elliot Hawkes and Bolin Liao are hoping to make a dent in. In a paper in the journal Device, the trio present an adaptive tile, which when deployed in arrays on roofs, can lower heating ...

WASHINGTON — For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive compact and stable laser sources that would be useful in a variety of applications, including the lidar systems used for autonomous vehicles. “We significantly reduced the size of a laser by using 3D printing to fabricate high-quality micro-optics directly on glass fibers used inside of lasers,” said research team leader Simon Angstenberger from the 4th Physics Institute at University of Stuttgart ...

PHILADELPHIA—(Dec. 13, 2023)—Wistar researchers successfully tested a simple intervention that could unlock greater anti-tumor power in therapies that use T cells — an approach known as “cell-based therapy,” which uses specially designed T cells to fight cancer. Led by Dr. Hildegund C.J. Ertl — a professor in The Wistar Institute’s Vaccine & Immunotherapy Center — the team has proven an exciting concept: that the common cholesterol drug fenofibrate can boost T cells’ ability to destroy human tumors, as described in their new paper, “Treatment ...

This holiday season brings surprising news about your Christmas tree. Scientists just discovered that globally, trees growing in wetter regions are more sensitive to drought. That means if your tree hails from a more humid clime, it’s likely been spoiled for generations. Scientists have long debated whether arid conditions make trees more or less resilient to drought. It seems intuitive that trees living at their biological limits will be most vulnerable to climate change, since even just a little extra stress could tip them past the brink. On the other hand, these populations have adapted to a harsher setting, so they might be more capable of withstanding a drought. According ...

URBANA, Ill. — When a sweet corn breeder reached out in 2021 to report severe injury from the herbicide tolpyralate, Marty Williams hoped it was a fluke isolated to a single inbred line. But two years later, after methodical field, greenhouse, and genetic testing, his new Pest Management Science study not only confirms sensitivity to tolpyralate in 49 sweet corn and field corn lines, but also reveals a new genetic vulnerability that may affect corn more generally. Tolpyralate is a relatively new ...
