| BPA exposure of the placenta could affect fetal brain development Posted: 12 Jan 2022 11:50 AM PST Scientists demonstrate the direct transmission of bisphenol A (BPA) from a mother to her developing child via the placenta could negatively impact fetal brain development. |
| Chewing to stay slim: How to savor your food better and dodge weight gain Posted: 12 Jan 2022 07:56 AM PST Chewing well helps in digestion. Chewing is also known to help prevent obesity, possibly by increasing the thermic effect of food consumption. But the factors behind this heat-generating effect of chewing remain less explored. A new study has revealed that oral stimuli, which are linked with the duration of tasting liquid food in the mouth, and the duration of chewing, play a positive role in increasing energy expenditure after food intake. |
| Why we feel confident about decisions we make Posted: 12 Jan 2022 07:56 AM PST A team of researchers has shown for the first time that decisions feel right to us if we have compared the options as attentively as possible -- and if we are conscious of having done so. This requires a capacity for introspection. |
| Chemical commonly found in consumer products may disrupt a hormone needed for healthy pregnancy Posted: 12 Jan 2022 06:40 AM PST Exposure to phthalates -- a group of chemicals found in everything from plastics to personal care products to electronics -- may disrupt an important hormone needed to sustain a healthy pregnancy, according to a new study. The study has examined the impact that phthalates, added to plastics to increase flexibility, have on the placental corticotropin releasing hormone (pCRH) that is produced by the placenta and increases throughout the course of pregnancy. |
| Learning through ‘guided’ play can be as effective as adult-led instruction up to at least age eight Posted: 12 Jan 2022 06:40 AM PST Teaching younger children through 'guided' play supports key aspects of their learning and development at least as well - and sometimes better - than the traditional direct instruction they usually receive at school, a new analysis finds. Guided play broadly refers to playful educational activities which, although gently steered by an adult using open-ended questions and prompts, give children the freedom to explore a learning goal in their own way. The new study gathered data about the impact of this approach on 3,800 children aged three to eight. It found that guided play can be just as effective as more traditional methods of classroom instruction in the development of key literacy, numeracy and social skills - as well as the acquisition of executive functions (a cluster of essential thinking skills). The findings also suggest that children may master some skills - notably in maths - more effectively through guided play than via other methods. |
| Remembering faces and names can be improved during sleep Posted: 12 Jan 2022 06:40 AM PST New research has documented the effect reactivating memory during sleep has on face-name learning. The researchers found that people's name recall improved significantly when memories of newly learned face-name associations were reactivated while they were napping. Key to this improvement was uninterrupted deep sleep. |
| Clothes dryers are an underappreciated source of airborne microfibers Posted: 12 Jan 2022 06:39 AM PST No one likes when their favorite clothes develop holes or unravel after many laundry cycles. But what happens to the fragments of fabric and stitching that come off? Although it's known that washing clothes releases microfibers into wastewater, it's unclear how drying impacts the environment. Now, a pilot study reports that a single dryer could discharge up to 120 million microfibers annually -- considerably more than from washing machines. |
| Breastfeeding reduces mothers’ cardiovascular disease risk Posted: 11 Jan 2022 06:13 AM PST Women who breastfed at some time in their lives were less likely to develop heart disease or stroke, compared to women who did not breastfeed, according to a meta-analysis of previous studies. Breastfeeding was also associated with a lower risk of dying from cardiovascular disease for the women. Previous research has also noted that the maternal health benefits of breastfeeding are associated with a lower risk of developing Type 2 diabetes and some cancers. |
| Higher olive oil intake associated with lower risk of CVD mortality Posted: 10 Jan 2022 11:52 AM PST Consuming more than 7 grams (>1/2 tablespoon) of olive oil per day is associated with lower risk of cardiovascular disease mortality, cancer mortality, neurodegenerative disease mortality and respiratory disease mortality, according to a new study. The study found that replacing about 10 grams/day of margarine, butter, mayonnaise and dairy fat with the equivalent amount of olive oil is associated with lower risk of mortality as well. |
