New hypothesis paper builds on a growing scientific consensus that Parkinson's disease route to the brain starts in either the nose or the gut and proposes that environmental toxicants are the likely source.
As in previous years, The New Social Worker is pleased to present the winning poems of the National Social Work Poetry Contest. The contest is sponsored by the University of Iowa School of Social Work. Congratulations to the Spring 2024 winners!
Star Trek's Holodeck is no longer just science fiction. Using AI, engineers have created a tool that can generate 3D environments, prompted by everyday language.
Iñaki Permanyer and Júlia Almeida Calazans Policymakers and scholars are increasingly interested in monitoring and curbing health inequalities. Much is known about the main causes of death and how mortality has been shifting from most deaths around the world being caused by communicable diseases towards most being due to non-communicable causes. However, less is known about the heterogeneity in these causes of death.
Researchers have discovered a simple, but effective, strategy to help people reduce their feelings of anger. Disposing of a piece of paper containing your written thoughts on the cause of your anger can effectively neutralize it. This process is like a Japanese tradition called hakidashisara, in which people write their negative thoughts on a plate then destroy it.
In a new breakthrough that could revolutionise medical and material engineering, scientists have developed a first-of-its-kind molecular device that controls the release of multiple small molecules using force.
Findings show a newly created drug can prevent runaway inflammation while still allowing the immune system to handle the virus, even when given late into infection.
The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies, thanks to a breakthrough guaranteeing security and privacy. This advance promises to unlock the transformative potential of cloud-based quantum computing.
A study showed that a genetic predisposition for higher muscle strength predicts a longer lifespan and a lower risk for developing common diseases. This is a highly comprehensive international study on hereditary muscle strength and its relationship to morbidity. The genome and health data of more than 340,000 Finns was used in the research.
Swimming in schools makes fish surprisingly stealthy underwater, with a group able to sound like a single fish. Engineers working with a high-tech simulation of schooling mackerel offer new insight into why fish swim in schools and promise for the design and operation of much quieter submarines and autonomous undersea vehicles.
Undertaking the majority of daily physical activity in the evening is linked to the greatest health benefits for people living with obesity, according to researchers who followed the trajectory of 30,000 people over almost 8 years.
Microplastic particles can be found in the most remote ocean regions on earth. In Antarctica, pollution levels are even higher than previously assumed.
Chimpanzees and bonobos are often thought to reflect two different sides of human nature -- the conflict-ready chimpanzee versus the peaceful bonobo -- but a new study shows that, within their own communities, male bonobos are more frequently aggressive than male chimpanzees. For both species, more aggressive males had more mating opportunities.
Pregnancy may carry a cost, reports a new study. The research shows that women who reported having been pregnant looked biologically older than women who had never been pregnant, and women who had been pregnant more often looked biologically older than those who reported fewer pregnancies.
A new study reveals the detailed protein structure of the TAS2R14, a bitter taste receptor that allows us to perceive bitter taste. In addition to solving the structure of this taste receptor, the researchers were also able to determine where bitter-tasting substances bind to TAS2R14 and how they activate them. The findings may lead to the development of drugs that targeting taste receptors.
Wildebeest migrations have become a rarer sight in Africa as humans continue to interrupt their historic migratory routes with roads, fences, cities, livestock and farmland. This has led to genetic decay in those herds that are no longer able to roam freely, according to new research.
Astrophysicists shed light on the relationship between the Milky Way and the Egyptian sky-goddess Nut. The paper draws on ancient Egyptian texts and simulations to argue that the Milky Way might have shone a spotlight, as it were, on Nut's role as the sky. It proposes that in winter, the Milky Way highlighted Nut's outstretched arms, while in summer, it traced her backbone across the heavens.
Cortisone and other related glucocorticoids are extremely effective at curbing excessive immune reactions. But previously, astonishingly little was known about how they exactly do that. Researchers have now explored the molecular mechanism of action in greater detail. As the researchers report, glucocorticoids reprogram the metabolism of immune cells, activating the body's natural 'brakes' on inflammation.
Researchers have developed a digital display screen where the LEDs themselves react to touch, light, fingerprints and the user's pulse, among other things. Their results could be the start of a whole new generation of displays for phones, computers and tablets.
In 2022, astronomers discovered the brightest gamma-ray burst (GRB) of all time. Now, astronomers confirm that a 'normal' supernova, the telltale sign of a stellar collapse, accompanied the GRB. The team also looked for signatures of heavy elements like gold and platinum in the supernova. They found no evidence of such elements, deepening the mystery of their origins.
Researchers have developed a technique to connect lab-grown neural 'organoids' (three-dimensional developmental brain-like structures grown from human stem cells) using axonal bundles, similar to the connections between regions in the human brain. This technique allows brain networks to be better represented experimentally in the lab, and will improve understanding and studies of network-related brain disorders.
Several similar large, fossilized bone fragments have been discovered in various regions across Western and Central Europe since the 19th century. The animal group to which they belonged is still the subject of much debate to this day. A study could now settle this dispute once and for all: The microstructure of the fossils indicates that they come from the lower jaw of a gigantic ichthyosaur.
Linking analyses of the moon's gravity field with models of its earliest evolution, scientists tell a story of the moon turning itself inside out after it solidified from a primordial magma ocean. The process left behind a vestige of dense, titanium-rich material beneath its Earth-facing side that makes its presence known by gravity anomalies.
An international research team has for the first time directly detected stellar winds from three Sun-like stars by recording the X-ray emission from their astrospheres, and placed constraints on the mass loss rate of the stars via their stellar winds.
Captured by cutting-edge radio telescope technology, a chance reactivation of a magnetar -- the Universe's most powerful magnets -- has revealed an unexpectedly complex environment.
A free throw in basketball will have every eye glued to one person. It's an intensely stressful situation. A research team studied whether a friendly tap on the shoulder increases the odds of making a shot.
When astronomers looked at a stellar pair at the heart of a stunning cloud of gas and dust, they were in for a surprise. Star pairs are typically very similar, like twins, but in HD 148937, one star appears younger and, unlike the other, is magnetic. New data suggest there were originally three stars in the system, until two of them clashed and merged.
Antarctica harbors a large concentration of meteorites imbuing the icy continent with an unparalleled wealth of information on our solar system. However, these precious meteorites are rapidly disappearing from the ice sheet surface due to global warming, according to a new study.
