Study identifies first drug therapy for sleep apnea
An international study shows new drug improves sleep, health in patients diagnosed with obesity and sleep apnea.
Simple test for flu could improve diagnosis and surveillance
Fewer than one percent of people who get the flu every year get tested, in part because most tests require trained personnel and expensive equipment. Now researchers have developed a low-cost paper strip test that could allow more patients to find out which type of flu they
Imaging technology captures how neurons communicate with new clarity
Insights from advanced imaging technology show how neurons communicate at the atomic level for the first time.
ChatGPT is biased against resumes with credentials that imply a disability -- but it can improve
Researchers found that ChatGPT consistently ranked resumes with disability-related honors and credentials -- such as the 'Tom Wilson Disability Leadership Award' -- lower than the same resumes without those honors and credentials. But when researchers customized the tool with
Potential targets for prevention and early identification of psychotic disorders
A new study found that nearly 75 per cent of young people with a psychotic disorder had at least one mental health service visit within the three years prior to their first diagnosis of the disorder.
How old is your bone marrow?
Our bone marrow the fatty, jelly-like substance inside our bones is an unseen powerhouse quietly producing 500 billion new blood cells every day. That process is driven by hematopoietic stem cells that generate all of the various types of blood cells in our bodies and
Study challenges popular idea that Easter islanders committed 'ecocide'
Some 1,000 years ago, a small band of Polynesians sailed thousands of miles across the Pacific to settle one of the world's most isolated places -- a small, previously uninhabited island they named Rapa Nui. Eventually, their numbers ballooned to unsustainable levels, they
Chilling discovery: Study reveals evolution of human cold and menthol sensing protein, offering hope for future non-addictive pain therapies
Menthol sensing appeared long before cold sensing, suggesting distinct activation modes that can be disentangled, paving the way for new pain therapies without adverse thermal side effects.
Boosting biodiversity without hurting local economies
Protected areas, like nature reserves, can conserve biodiversity without harming local economic growth, countering a common belief that conservation restricts development. A new study outlines what is needed for conservation to benefit both nature and people.
Tropical storms like Alberto can lead to years of declining incomes
The long-term economic effects of tropical cyclones far outweigh the direct damages from high winds and flooding, with local incomes declining for years after the storm hits
Print Edition 55: The Rebel Issue
Issue 55 of the Nautilus print edition is our Rebel Issue. It includes contributions from science writer Elena Kazamia, astrophysicist Paul M. Sutter, film producer Namir Khaliq, philosopher Jonathon Keats, and more. This issue also features new illustrations by Angie Wang and
Jupiter’s Great Red Spot may have disappeared and reformed
The Earth-sized storm on Jupiter known as the red spot was thought by many to have been first observed in 1665, but it turns out that may have been an entirely different enormous storm, with today's storm dating back only to 1831
Remembering Lynn Conway, of the Conway Effect, Who Helped Launch the Computing Revolution
Lynn Conway, a trans woman and advocate for LGBTQ rights, was underappreciated and often underrecognized for her work in chip design
Easter Island's legendary societal collapse didn't actually happen
Historians have claimed the people of Easter Island overexploited natural resources, causing a population crash, but new evidence suggests they lived sustainably for centuries
Key mechanism in nuclear reaction dynamics promises advances in nuclear physics
Researchers have made significant progress in understanding the transfer of neutrons in weakly bound nuclei. The experiment, performed at Legnaro National Laboratory, focused on the one-neutron stripping process in reactions involving lithium-6 and bismuth-209. The work is
Beneficial bacteria help these marine worms survive extreme cold
Three species of marine worms living in Antarctic waters have beneficial relationships with bacteria that produce antifreeze proteins.
A new study challenges the idea that Rapa Nui islanders caused an ‘ecocide’
Rapa Niu islanders farmed and fished enough to feed only a few thousand people, too few to decimate society before Europeans arrived, researchers contend.
New AI-driven tool improves root image segmentation
In a world striving for sustainability, understanding the hidden half of a living plant—the roots—is crucial. Roots are not just an anchor; they are a dynamic interface between the plant and soil, critical for water uptake, nutrient absorption, and, ultimately, the survival of
Exploring the roots of the Anthropocene
Understanding how tropical land use and deforestation affects the dynamics of the global Earth system and identifying potential tipping points are key to the future of our species on this planet. By exploring the long history of human societies in tropical forests and bringing
Unlocking the entrepreneurial brain: New perspectives on cognitive flexibility
In a recent study led by the University of Liège researchers delved into the intersection of the fields of entrepreneurship and neuroscience, looking specifically at the cognitive flexibility of habitual entrepreneurs—those who repeatedly launch new businesses—compared to less
Many more bacteria produce greenhouse gases than previously thought, study finds
Caltech researchers have discovered a new class of enzymes that enable a myriad of bacteria to "breathe" nitrate when in low-oxygen conditions. While this is an evolutionary advantage for bacterial survival, the process produces the greenhouse gas nitrous oxide (N2O) as a
Protecting Artists from Theft by AI
A new strategy for copyrighting a writer’s signature style. The post Protecting Artists from Theft by AI appeared first on Nautilus .
Human activity: A double-edged sword in the face of drought
Earth and environmental scientists have reported that, as human socio-economic activities increase, greenhouse gas emissions will rise, leading to more frequent extreme weather events such as droughts and floods. However, a research team from Pohang University of Science and
Ariane 6 launches: Splashdown for Nyx Bikini
Europe's newest rocket soon launches, taking with it many space missions each with a unique objective, destination and team at home, cheering them on. Whether launching new satellites to look back and study Earth, peer out to deep space or test important new technologies in
After ISIS bombs, an urgent call to preserve an ancient Syrian temple
The Temple of Bel stands in the ancient Syrian city of Palmyra, adjoining a desert oasis with palm trees and bountiful water. Constructed in the first two centuries of the Common Era, the temple served for nearly two thousand years as a sanctuary for locals and as a site of
How E. coli defends itself against antibiotics
Imagine that you have a very sore throat. You're sick, your throat hurts, and a visit to the doctor confirms that the pain is due to a bacterial infection. You get a prescription for antibiotics, which quickly sorts out your sore throat. You are pleased that the treatment has
Latin American cattle block road to Paris goals
Dense forest and patchy regulations mean Latin America is struggling to shake off its mantle as the world's leading emitter of greenhouse gas from livestock production.
