- newPressure to be 'perfect' causing burnout for parents, mental health concerns for their children
Is the status of 'perfect parent' attainable? Researchers leading a national dialogue about parental burnout say 'no,' and a new study finds that pressure to try to be 'perfect' leads to unhealthy impacts on both parents and their children.

- new'Mathematical microscope' reveals novel, energy-efficient mechanism of working memory that works even during sleep
Researchers have discovered a mechanism that creates memories while reducing metabolic cost, even during sleep. This efficient memory occurs in a part of the brain that is crucial for learning and memory, and where Alzheimer's disease begins.

- newTHC lingers in breastmilk with no clear peak point
When breastfeeding mothers in a recent study used cannabis, its psychoactive component THC showed up in the milk they produced. The research also found that, unlike alcohol, when THC was detected in milk there was no consistent time when its concentration peaked and started to decline. Importantly, the researchers discovered that the amount of THC they detected in milk was low -- they estimated that infants received an average of 0.07 mg of THC per day. For comparison, a common low-dose edible c…

- newCould getting enough sleep help prevent osteoporosis?
In people's early- to mid-20s, they reach what is called peak bone mineral density, which is higher for men than it is for women, according to researchers. This peak is one of the main determinants of fracture risk later in life. After reaching this peak, a person's bone density remains roughly stable for a couple of decades. Then, when women enter the menopausal transition, they experience accelerated bone loss. Men also experience bone density decline as they age. Sleep patterns also evolve ov…

- newBiomarker found to help identify cells that can repair damaged blood vessels
Researchers have discovered a protein marker to help identify cells able to repopulate in patients with damaged blood vessels. Their findings could lead to new therapies for people with endothelial dysfunction, a type of disorder that contributes to coronary artery disease that may occlude with plaque and lack ability to carry sufficient blood into the heart tissue causing a heart attack.

- newSedentary lifestyle puts strain on young hearts
According to a recent study, high levels of sedentary behavior and physical inactivity from childhood strain the heart in adolescence. High cardiac workload predicts heart failure and other heart diseases. In light of the findings, increasing moderate and vigorous physical activity from childhood onwards is particularly important in preventing heart diseases.

- newIntermittent fasting protects against liver inflammation and liver cancer
Fatty liver disease often leads to chronic liver inflammation and can even result in liver cancer. Scientists have now shown in mice that intermittent fasting on a 5:2 schedule can halt this development. The fasting regime reduces the development of liver cancer in mice with pre-existing liver inflammation. The researchers identified two proteins in liver cells that are jointly responsible for the protective effect of fasting. An approved drug can partially mimic this effect.

- newSeeking medical insights in the physics of mucus
Understanding how mucus changes, and what it changes in response to, can help diagnose illnesses and develop treatments. Researchers develop a system to grow mucus-producing intestinal cells and study the characteristics of the mucus in different conditions. The process involves growing a layer of intestinal cells on a laboratory plate exposed to air. These cells produce a layer of mucus that the researchers can easily access for testing. Using a magnetic wire, they can measure the consistency o…

- newStudy sheds light on cancer cell 'tug-of-war'
Researchers used a breast cancer cell line panel and primary tumor explants from breast and cervical cancer patients to examine two different cellular contractility modes: one that generates collective tissue surface tension that keeps cell clusters compact and another, more directional, contractility that enables cells to pull themselves into the extracellular matrix. They found that more aggressive cells pull more strongly on the ECM than on themselves while noninvasive cells pull more strongl…
