The blood thinner apixaban was not superior to standard of care following transcatheter aortic valve replacement (TAVR), according to findings from a new trial called ATLANTIS presented at the American College of Cardiology's 70th Annual Scientific Session.

Flatiron Institute researchers have made a breakthrough in accounting for the mysterious lack of exoplanets roughly double Earth's radius -- an enigma called the radius gap. Using data from the Kepler spacecraft, the researchers found that the sizes of the 'missing planets' depends on the ages of the planetary systems. Specifically, the researchers propose that gas-shrouded exoplanets shrink drastically over billions of years, leaping over the radius gap to become relatively smaller rocky super-Earths.

New research has shown that people with type 1 diabetes may have features of premature heart disease induced by the condition often before they even get their diagnosis.

As presented at ACC.21 and published in NEJM, the findings from ADAPTABLE are from the largest aspirin dosing trial conducted in routine care and clinical settings using PCORnet, a national resource advancing more efficient clinical research. The study and trial were funded by the Patient-Centered Outcomes Research Institute and conducted by a research team led by the Duke Clinical Research Institute.

The study tracked 4,811 people in 27 countries who are living with atrial fibrillation and taking blood thinners. Consenting patients undertaking cardiopulmonary bypass surgery were randomly selected for the additional left atrial appendage occlusion surgery; their outcomes compared with those who only took medicine. They were all followed for a median of four years.

Researchers at Rutgers Robert Wood Johnson Medical School are reporting the first instance of COVID-19 triggering a rare recurrence of potentially serious blood clots in people's arms.

A new study has found that even with clinics nearby, many women choose telehealth visits and the US Postal Service for prescriptions. 

Scientists from China have sequenced and analyzed the genome of lavender to provide insights into what causes its distinct aroma. Their findings shed light into the evolution of this uniquely fragrant plant, which could pave the way for creating improved lavender varieties besides adding to existing knowledge on the evolution, phytochemistry, and ecology of Lamiaceae, the plant family to which lavender belongs.

Etching the oxide overlayers of metal phosphide electrocatalysts can accelerate the process of surface reconstruction and facilitate the formation of key intermediate phases for catalyzing water electrolysis.

The team discovered a compound that prevents and even reverses the underlying physiological change that can lead some drugs to cause heart problems.

People with a high polygenic risk score for colorectal cancer could benefit more at preventing the disease by leading healthy lifestyles than those at lower genetic risk, according to a study by Vanderbilt researchers published in the April issue of The American Journal of Clinical Nutrition.

Next-generation sequencing technology has made it easier than ever for quick diagnosis of plant diseases. "It's really exciting to see how sequencing technologies have evolved and how this new technology facilitates sequencing of entire genomes in such a short amount of time," said Yazmín Rivera, a plant pathologist with the United States Department of Agriculture's Plant Protection and Quarantine program, who recently published a research paper on the efficacy of Oxford Nanopore Technologies protocols.

A new class of bio-inspired two-dimensional (2D) hybrid nanomaterials mimic the ability of photosynthetic plants and bacteria.

In a large-animal study, researchers have shown that heart attack recovery is aided by injection of heart muscle cells derived from human induced pluripotent stem cell line, or hiPSCs, that overexpress cyclin D2. This research, published in the journal Circulation, used a pig model of heart attacks, which more closely resembles the human heart in size and physiology, and thus has higher clinical relevance to human disease, compared to studies in mice.

CSHL scientists genetically profiled thousands of cells in normal breast tissue to establish what types of cells tend to become cancerous. This catalog can help researchers develop preventive therapies.

Three billion years ago, light first zipped through chlorophyll within tiny reaction centers, the first step plants and photosynthetic bacteria take to convert light into food.

University of Illinois Urbana-Champaign researchers use frontal polymerization to manufacture environmentally-adaptive multifunctional materials in a matter of minutes instead of days.

A new study investigated the impact of perpetrators' gender, sexuality, and age on perceptions of teacher sexual misconduct. The study found that responses to teachers' misconduct varied according to certain characteristics, which can influence whether victims report the misconduct.

Cyanobacteria first evolved to perform photosynthesis about 2.4 billion years ago, pumping tons of oxygen into the atmosphere - a period known as the Great Oxygenation Event - which enabled the evolution of multicellular life forms. Led by BTI faculty member Fay-Wei Li, researchers have discovered a new species of cyanobacteria, Anthocerotibacter panamensis, which could help illuminate how photosynthesis evolved to create the world as we know it.

Better designed vaccines for insect-spread viruses like dengue and Zika are likely after researchers discovered models of immature flavivirus particles were originally misinterpreted.Researchers from The University of Queensland and Monash University have now determined the first complete 3D molecular structure of the immature flavivirus, revealing an unexpected organization.
