Medical researchers have performed a successful transcatheter tricuspid valve repair procedure with a groundbreaking catheter.
A clinical trial showed that a nasal spray that patients administer at home, without a physician, successfully and safely treated recurrent episodes of a condition that causes rapid abnormal heart rhythms. The study provides real-world evidence that a wide range of patients can safely and effectively use the experimental drug, called etripamil, to treat recurrent paroxysmal supraventricular tachycardia (PSVT) episodes at home, potentially sparing them the need for repeated hospital trips for more invasive treatments.
A team reveals a clear link between human-driven climate change and the years-long drought currently gripping southern Madagascar.
Higgs predicted the existence of a new particle — the so-called Higgs boson — in 1964
Microplastic particles can be found in the most remote ocean regions on earth. In Antarctica, pollution levels are even higher than previously assumed.
Relapses in a common form of leukemia may be preventable following new research that has identified how the cancer develops resistance to first line treatments.
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.
The first birdfeeders were made in the 19th century, and their design rapidly evolved during the 20th century. Researchers at the consider the evolution of the birdfeeder to be an example of multispecies design, where unwanted guests have shaped the human-made artifact.
Scientists from Macquarie University have come up with an innovative way to stop cane toads killing native wildlife by training goannas to avoid eating the deadly amphibians.
Fish and invertebrate animals are far more affected by warmer and more acidic seawater than was previously known. The big gain of the new method is that more details become known about effects of climate change on species.
A study that could help revolutionize wireless communication introduces a novel method to curve terahertz signals around an obstacle.
Through the ages, the presence of humans has increased the heterogeneity and complexity of ecosystems and has often had a positive effect on their biodiversity.
Researchers have made a significant advancement toward understanding how the human genome is organized inside a single cell. This knowledge is crucial for analyzing how DNA structure influences gene expression and disease processes.
Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.
Worldwide over the past 35 years, dams and land reclamation activities converted 250,000 acres of estuary -- an area roughly 17 times the size of Manhattan -- to urban land or agricultural fields, with most land conversion and estuary loss in rapidly developing countries, a new study finds. The findings could help developing countries avoid problems faced by countries that have already lost or degraded their estuaries.
A new expert consensus statement aims to improve endometriosis evaluation. Endometriosis is a common condition with substantial diagnostic delay, leading patients to experience pain, infertility, lost wages and interrupted relationships. The consensus provides recommendations for augmenting routine pelvic ultrasounds through additional maneuvers and imaging to improve diagnosis of deep endometriosis.
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. These animals could reach 25 to 30 meters in length, a similar size to the modern blue whale.
The findings may also have implications for learning and memory disorders, including Fragile X syndrome.
Understanding how social media is used during a disaster can help with disaster preparedness and recovery for future events.
Investigators have assembled the most comprehensive atlas to date of messenger RNA (mRNA) variants in the mouse and human brain. The atlas is an important new resource in understanding brain development, neuron specialization and other brain functions.
