Medical Xpress / GLP-1 drugs tied to lower-calorie, lower-sugar food purchases
Researchers at Steno Diabetes Center Copenhagen reported that starting a GLP-1 receptor agonist (GLP-1RA) coincided with slightly healthier supermarket purchases. Grocery purchases from GLP-1RA users in Denmark contained ...
Medical Xpress / Premature aging may result from immune responses triggered by faulty DNA repair
DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that aid DNA in carrying out essential processes such as replication, repair, and transcription. Under ...
Medical Xpress / Shingles vaccination associated with delayed dementia onset in older adults
Every three seconds, someone, somewhere in the world, develops dementia. The number of people living with the condition is projected to rise dramatically, doubling from 78 million in 2020 to 139 million by 2050, making dementia ...
Phys.org / Ancient Alaskan site may help explain how the first people arrived in North America
New evidence has emerged that sheds light on the possible first people to populate the Americas. Dating of stone and ivory tools found at an archaeological site in Alaska suggests that these early pioneers traveled through ...
Phys.org / Reproduction in space, an environment hostile to human biology
As commercial spaceflight draws ever closer and time spent in space continues to extend, the question of reproductive health beyond the bounds of planet Earth is no longer theoretical but now "urgently practical," according ...
Phys.org / Political division in the US surged from 2008 onward, study suggests
Divisions within the US population on social and political issues have increased by 64% since 1988, with almost all this coming after 2008, according to a study tracking polarization from the end of the Reagan era to the ...
Phys.org / Supermassive black holes sit in 'eye of their own storms,' studies find
Gigantic black holes lurk at the center of virtually every galaxy, including ours, but we've lacked a precise picture of what impact they have on their surroundings. However, a University of Chicago-led group of scientists ...
Phys.org / A student made cosmic dust in her lab—what she found could help us understand how life started on Earth
A Sydney Ph.D. student has recreated a tiny piece of the universe inside a bottle in her laboratory, producing cosmic dust from scratch. The results shed new light on how the chemical building blocks of life may have formed ...
Phys.org / A new class of strange one-dimensional particles
Physicists have long categorized every elementary particle in our three-dimensional universe as being either a boson or a fermion—the former category mostly capturing force carriers like photons, the latter including the ...
Medical Xpress / Nearly half of chronic fatigue patients test positive for Bartonella or Babesia infection
A pilot study has found evidence of Bartonella and Babesia infection in almost half of 50 blood samples from patients suffering chronic fatigue syndrome, also called myalgic encephalomyelitis (ME). The study appears in Pathogens.
Phys.org / 91-qubit processor accurately simulates many-body quantum chaos
Quantum chaos describes chaotic classical dynamical systems in terms of quantum theory, but simulations of these systems are limited by computational resources. However, one team seems to have found a way by leveraging error ...
Tech Xplore / Neptunium study yields plutonium insights for space exploration
Researchers at the Department of Energy's Oak Ridge National Laboratory are breathing new life into the scientific understanding of neptunium, a unique, radioactive, metallic element—and a key precursor for production of ...
