American Indians and Alaska Natives living below the poverty line face sharply higher rates of food insecurity than other impoverished adults—nearly 4 in 10 lack consistent access to a healthy diet.
Researchers at the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC analyzed brain imaging and clinical data from more than 17,000 participants across five major aging and Alzheimer's disease studies.
Scientists have discovered that the southern Andes Mountains don't rise slowly and steadily as previously thought. Instead, the range builds itself in short, powerful "pulses" every few million years.
Goats appear to have a rare ability not shared by many in the animal kingdom, and that is being able to follow the direction of a human voice to locate hidden objects. While dogs have been shown to do this, even our closest primate cousins, like chimpanzees, have struggled with the task in previous experiments.
Consumers often assume that hand-prepared foods are fresher, higher quality and safer than factory-packaged alternatives, but a new study co-authored by a University of Massachusetts Amherst researcher suggests those assumptions may overlook important food safety considerations—and that targeted messaging can significantly change purchase intentions.
Women who lift weights may have a lower risk of major heart disease, especially when combined with aerobic exercise, according to a new study published in JACC. Findings show that heart health is better understood by looking at overall movement habits, rather than focusing on single behaviors alone, and resistance training can result in additional health benefits when incorporated into an active lifestyle.
An international team of scientists has identified a completely new type of rock from the red planet and, for the first time, discovered the mineral garnet in a Martian sample. The breakthrough offers a rare glimpse into Mars' ancient past and could help researchers piece together the planet's 4.5-billion-year geological history. The discovery was made by an international research team including James Darling, professor of Earth and planetary science, from the University of Portsmouth's School of the Environment and Life Sciences.
A new study led by researchers at The University of Texas MD Anderson Cancer Center has uncovered a previously unknown connection between nucleic acid structures called R-loops and age-related inflammation—or inflammaging—that could herald new intervention options for chronic inflammation and the subsequent health conditions.
Yo-yo dieters who struggle to lose weight and keep it off may achieve better results by following an intermittent fasting diet, rather than traditional calorie counting. An Adelaide University study focusing on the psychological aspects of both intermittent fasting and calorie restriction compared the effects the diets had on eating behaviors, mood, sleep and quality of life. The research is published in the journal Clinical Nutrition.
Physicists have long been drawn to the nonlinear Hall effect: a subtle variant of the classical Hall effect, in which an electric voltage appears perpendicular to a current flowing through a material. Unlike its classical counterpart, the nonlinear version can arise even without breaking time-reversal symmetry, and its magnitude is tied to deep geometric properties of electron wave functions. So far, however, the behavior of the effect when a magnetic field is applied has remained poorly understood.
UniQure will submit Huntington's therapy for approval, Eli Lilly buys 4E Therapeutics, and more biotech news
As the Democratic Republic of the Congo is battling an Ebola disease outbreak caused by the Bundibugyo virus, the World Health Organization (WHO) has released its first comprehensive guidelines for the clinical management of filovirus disease which include all types of Ebola and Marburg viruses. The new guidelines highlight the importance of early supportive care to improve patient survival and health outcomes, outlining 16 evidence-based recommendations.
A new University of Otago—Ōtākou Whakaihu Waka-led study has put its own spin on Pavlov's dog experiment, shining a light on how our brain learns new things. The study, "The superior colliculus gates dopamine responses to conditioned stimuli in visual classical conditioning" is published in Nature Communications.
Systematic reviews and meta-analyses form the basis for health care and health policy, but access to the data on which the results are based is often lacking. This is shown in a new policy forum article from Karolinska Institutet published in the journal PLOS Medicine.
An international research collaboration between the University of Vienna and Lawrence Berkeley National Laboratory in the United States has used machine learning to re-examine one of the most debated signals in astrophysics. The so-called Galactic Center Excess (GCE), a faint, roughly spherical glow of gamma rays at the center of the Milky Way, has fascinated physicists for more than a decade. The new results suggest that an explanation in terms of dark matter cannot currently be ruled out. The results have now been published in the journal Physical Review Letters.
A cyber extortion group claimed to have stolen more than a terabyte of data from Novo Nordisk and said it is exploring selling some of the data
A new study from the University of Nebraska–Lincoln sheds light on how parental smoking shapes adolescents' attitudes and use of both traditional cigarettes and e-cigarettes, finding that fathers' behaviors may play a more influential role than those of mothers. Led by Alex Mason, a professor in the Department of Child, Youth and Family Studies, the research tracked 230 children from preschool through adolescence, examining how repeated exposure to smoking behaviors within the home affects later smoking and vaping behaviors by teens.
A new study led by Marco Fumasoni, principal investigator at Fundação GIMM, shows that evolution can substantially reduce cell size without significantly compromising cells' ability to grow. The work, carried out in yeast in collaboration with researchers at Cornell University, is published in Proceedings of the National Academy of Sciences.
Medical large language models (LLMs) are increasingly being used in clinical settings. For example, AI is helping doctors in emergency rooms flag diagnoses or support decisions. The problem is that most of these systems are proprietary: Their training data, design choices and decision-making processes are hidden from view, making independent review virtually impossible.
Climate change could push UK rivers to dangerous extremes and bring more frequent rapid swings between wet and dry conditions—a phenomenon known as hydroclimatic whiplash—according to research led by the University of East Anglia (UEA). Researchers analyzed almost 700 river catchments across the UK to project how river flows may change at 2° C and 4° C of global warming. The results reveal stark regional contrasts and growing challenges for communities and water managers trying to plan for flood and drought risk, particularly in areas that will increasingly experience both.
