Renewing a legal battle that some had considered settled, gun rights advocates filed a federal lawsuit this week challenging a California law that places a 10-day waiting period on most firearm purchases.The law, which requires people to wait the prescribed "cooling off" period even if they've passed a more immediate background check, is aimed in part at deterring people from rushing to harm themselves or others with newly purchased weapons during periods of sudden distress or anger.

Breast density is known to naturally decrease as a woman ages, and now a study suggests that the more time it takes for breast density to decline, the more likely it is that the woman could develop breast cancer.Researchers have long known that women with dense breasts have a higher risk of breast cancer.

We moved across the street from the Metra train station in 2019 so that my husband could sprint haphazardly across the street just as the train was rolling in and still make it to work on time.We didn't fully anticipate that every antique leaded window and old-forest wooden crossbeam in our 100-year-old house would shake and rattle with each passing train.

Up to 60% of all stroke survivors develop memory and thinking problems within a year, and one-third go on to develop dementia within five years, according to a new American Stroke Association scientific statement.The numbers are staggering, right? said Dr. Andrew Freeman, director of cardiovascular prevention and wellness at National Jewish Health in Denver.

Although many children have returned to school and nursery, not every mum has the help she needs yet.For most of the first year after her daughter was born in early 2022, Katie Szerbin worked from home, managing customer service calls all day, without any kind of childcare.Each time her child began to cry, the 30-year-old mother from New Jersey, US, had to leave the room.

Boffins at the University of California, Berkeley, have delved into the undisclosed depths of OpenAI's ChatGPT and the GPT-4 large language model at its heart, and found they're trained on text from copyrighted books.Academics Kent Chang, Mackenzie Cramer, Sandeep Soni, and David Bamman describe their work in a paper titled, "Speak, Memory: An Archaeology of Books Known to ChatGPT/GPT-4."
"We find that OpenAI models have memorized a wide collection of copyrighted materials, and that the degree of memorization is tied to the frequency with which passages of those books appear on the web," the researchers explain in their paper.

A new study by researchers at the University of Colorado Boulder found that Black and Latina mothers in the US may have been induced into labor based on the needs of White pregnant women and not their own.The study, published Wednesday in the American Sociological Association's Journal of Health and Social Behavior, suggests systemic racism may be shaping obstetric care in the United States.

Hostile parenting and harsh discipline increase the likelihood of lasting mental health problems in children, a report suggests.New research said parenting that involves frequently shouting at, isolating, and physically punishing young children made it 1.5 times more likely that a child would be at high risk of developing poor mental health by age nine.

The portion of American hospital beds occupied by children with suicidal or self-harming behavior has soared over the course of a decade, a large study of admissions to acute care hospitals shows.An analysis of 4,767,840 pediatric hospitalizations by researchers at Dartmouth, published on Tuesday in the medical journal JAMA, found that between 2009 and 2019, mental health hospitalizations increased by 25.8 percent and cost $1.37 billion.

For someone whose career has been spent addressing the urgency of climate change, environmental-politics researcher Leah Stokes sounded awfully cheery in a talk in early March at the SXSW conference in Austin.I'm not telling you don't dry your clothes, don't cook your food, don't drive anywhere,' Stokes, an associate professor at the University of California, Santa Barbara, told the crowd.

Scientists have long known that dense breast tissue is linked to an increased risk of breast cancer in women.A study published on Thursday in JAMA Oncology adds a new twist, finding that while breast density declines with age, a slower rate of decline in one breast often precedes a cancer diagnosis in that breast.
