Brain imaging of neuron activity in certain areas of the brain may predict whether an individual is likely to successfully respond to interventions to reduce their drinking. In a study published in Alcohol: Clinical and Experimental Research, individuals whose baseline imaging showed decreased activity in areas of the brain associated with reward processing and impulsivity and increased activity in regions responsible for complex cognitive processes and emotional regulation were more likely to reduce their drinking following an intervention.
A new study reports conclusive evidence for the breakdown of standard gravity in the low acceleration limit from a verifiable analysis of the orbital motions of long-period, widely separated, binary stars, usually referred to as wide binaries in astronomy and astrophysics.
Researchers at the University of Illinois Urbana-Champaign demonstrated a way to use electricity to recycle polyoxymethylene (POM), a form of plastic that’s growing in use but more challenging to recycle.
Although many Americans dutifully deposit their plastic trash into the appropriate bins each week, many of those materials, including flexible films, multilayer materials and a lot of colored plastics, are not recyclable using conventional mechanical recycling methods. In the end, only about 9 percent of plastic in the United States is ever reused, often in low-value products.
An international research team details changes in DNA that researchers found are shared by humans and other mammals throughout history and are associated with life span and numerous other traits.
Scientists working on Fermilab’s Muon g-2 experiment released the world’s most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown between theory and experiment that may uncover new particles or forces.
People who take acid reflux medications called proton pump inhibitors for four-and-a-half years or more may have a higher risk of dementia compared to people who do not take these medications, according to new research published in the August 9, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. This study does not prove that acid reflux drugs cause dementia; it only shows an association.
A Kaiser Permanente study provides new information that may help oncologists answer one of the most common questions they hear from breast cancer survivors: Is it safe to drink alcohol?
The surface of Mars, unlike the Earth's, is not constantly renewed by plate tectonics. This has resulted in the preservation of huge areas of terrain remarkable for their abundance in fossil rivers and lakes dating back billions of years.
The first gene mapping study on human scalp hair whorls not only shows that hair whorl direction has a genetic basis, but also that it is affected by multiple genes.

The impact of particulate matter air pollution on death and disability is on the rise worldwide, according to new research published today in the Journal of the American Heart Association.
In 1956, theoretical physicist David Pines predicted that electrons in a solid could form a composite particle called a demon. It's eluded detection since its prediction....until now.
Detecting extremely distant stars, or those closest in time to the big bang, can provide insights into the first few chapters of the history of our universe. In 2022, the Hubble Space Telescope broke its own record, and spotted the most distant star yet. This star, nicknamed Earendel, emitted its light within the universe’s first billion years.
Blood disorders known as myelodysplastic syndromes/neoplasms are commonly misdiagnosed – putting patients at increased risk for treatment mistakes and other potentially harmful consequences. A new study highlights the vital need for strong coordination between clinicians and skilled pathologists to ensure accurate, timely diagnosis of blood cancers.
After more than a decade of work, electrons are now flying through a new superconducting accelerator at the Department of Energy’s SLAC National Accelerator Laboratory, preparing to power the world’s most powerful X-ray free electron laser. This project – named the Linac Coherent Light Source II (LCLS-II) – is now steps away from releasing X-ray flashes that will open a new era in scientific research at that atomic level.
Yasemin Ozkan-Aydin, electrical engineering doctoral student Nnamdi Chikere and undergraduate John Simon McElroy, a Naughton Fellow from University College Dublin, have designed and built a robotic sea turtle, which they are testing in varied environments on Notre Dame’s campus. Their robot mimics a real sea turtle’s propulsion: its front flippers move it forward while its smaller hind flippers allow it to change direction.
Researchers at Dana-Farber Cancer Institute have created an AI-based tool that uses tumor gene sequencing data to predict the primary source of a patient’s cancer. The study, published in in Nature Medicine, suggests that this predictive tool, called OncoNPC, could help guide treatment of cancer and improve outcomes in difficult to diagnose cases.
As artificial intelligence systems like ChatGPT find their way into everyday use, physicians will start to see these tools incorporated into their clinical practice to help them make important decisions on diagnosis and treatment of common medical conditions.
New study identifies concerning gaps between how human radiologists score the accuracy of AI-generated radiology reports and how automated systems score them.

A first-of-its-kind analysis of historical DNA ties tens of thousands of living people to enslaved and free African Americans who labored at an iron forge in Maryland known as Catoctin Furnace soon after the founding of the United States. The study, spurred by groups seeking to restore ancestry knowledge to African American communities, provides a new way to complement genealogical, historical, bioarchaeological, and biochemical efforts to reconstruct the life histories of people omitted from written records and identify their present-day relatives.
In a first, scientists define five types of colon neurons specialized for sending different signals to the brain.
The number of girls diagnosed with precocious puberty increased during the COVID-19 pandemic due to potential risk factors such as increased screen time and less physical activity, according to a new study published in the Journal of the Endocrine Society.
Teens who have been bullied by their peers, or who have considered or attempted suicide, may be more likely to have more frequent headaches than teens who have not experienced any of these problems, according to a study published in the August 2, 2023, online issue of Neurology®, the medical journal of the American Academy of Neurology. The study does not prove that bullying or thoughts of suicide cause headaches; it only shows an association.
