Deeper sleep is more likely to lead to eureka moments, study indicates

The Trump administration's new vaccine advisers on Thursday endorsed this fall's flu vaccinations for just about every American—but only if they use certain shots free of an ingredient antivaccine groups have falsely tied to autism.

A new article published in Nature offers a promising path toward a shorter, more effective treatment for tuberculosis (TB), a bacterial disease that affects millions worldwide.

Moyamoya disease—a rare, progressive condition that narrows the brain's blood vessels—leads to an increased risk of stroke and other neurological conditions. Doctors treating children with moyamoya often face difficult decisions about treatment, notably deciding whether to perform revascularization, a surgery to bypass the narrowed blood vessels and restore blood flow.

Researchers at the Max Planck Florida Institute for Neuroscience have discovered how loss of a gene strongly associated with autism and macrocephaly (large head size) rewires circuits and alters behavior.

A new cancer drug candidate has demonstrated the ability to block tumor growth without triggering a common and debilitating side effect.

A recent study has shed light on the brain structure differences associated with psychopathy—a condition known to be one of the strongest predictors of persistent violent behavior.

Researchers have found that even after recovery, individuals who previously experienced depression may retain a heightened sensitivity to negative cues and face challenges in regulating responses to potential punishment.

Most patients undergoing "tummy tuck" surgery (abdominoplasty) to remove excess skin and tissue after weight loss continue to lose weight in the months and years after surgery, suggests new research.

Four discrete cross-sectional surveys of US adults from 2020–2024 reveal US adults reporting high confidence in the Centers for Disease Control and Prevention (CDC) dropped from 82% in February 2020 to a low of 56% in June 2022, according to a study published in PLOS Global Public Health by Amyn A. Malik and colleagues from UT Southwestern Medical Center, United States.

For decades, oral health care has mainly focused on preventing cavities and gum disease. However, scientific research has increasingly highlighted the importance of the oral microbiome—a set of microorganisms that naturally inhabit the oral cavity. Recent studies have shown links between imbalances in this microbial ecosystem and the development of head and neck cancers, as well as a growing body of evidence associating it with colorectal cancer.

Most people experience periods of loneliness, isolation or solitude in their lives. But these are different things, and the proportion of people feeling lonely is stable over time. So why do we keep talking about an epidemic of loneliness?

A major UK-led clinical trial has found that a treatment commonly used to help premature babies breathe offers no benefit for infants on life support with severe bronchiolitis—a seasonal viral illness that hospitalizes thousands of babies each year.

Empagliflozin has kidney protective effects and reduces heart failure outcomes across baseline kidney function among patients with acute myocardial infarction (MI), according to a study published online June 13 in Nature Cardiovascular Research.

A research team has made a significant finding that sheds new light on dementia with Lewy Bodies (DLB). The team was led by Associate Professor Ayako Okado-Matsumoto from the Department of Biology at Toho University in collaboration with Professor Ryuji Sakakibara from the Department of Neurology at Sakura Medical Center, and Professors Hitoshi Nukada and Soroku Yagihashi from the Department of Exploratory Medicine on Nature, Life and Man at Toho University.

Prior studies have shown veterans are particularly at risk of dying by opioid overdose and the possibility of that occurring has been rising steadily over the past two decades. From 2010–2019, there was a 61.2% increase in risk of overdose death among male veterans.

Research carried out on mice has revealed how a hormone released by the intestine acts on the brain and helps regulate the body's energy expenditure. FGF19 (fibroblast growth factor 19) activates mechanisms that stimulate the use of more energy, burn fat, and favor weight control and blood glucose levels in obese animals.

Exposure to fire smoke—which can be composed of particulate matter, gases, materials from buildings such as perfluoroalkyl and polyfluoroalkyl substances (PFAS), toxic metals, and carcinogenic compounds—may alter the immune system on a cellular level, according to a new study led by researchers at Harvard T.H. Chan School of Public Health. The study is the first to examine the specific cellular changes associated with fire smoke exposure, documenting how smoke can damage the body through the immune system.

In a recent study published in World Journal of Experimental Medicine, scientist Dr. Renee Dufault at the Food Ingredient and Health Research Institute provides a protocol for determining the role ultra-processed foods play in prenatal heavy metal exposures and changes in the expression of the zinc dependent MT-1 (metallothionein) gene that impacts child neurodevelopment.
