Water is a mysterious substance. Understanding how it behaves at the atomic level is still a challenge for experimental physicists, as light hydrogen and oxygen atoms are difficult to observe using conventional experimental methods. This is especially true for any researcher looking to study the microscopic movements of individual water molecules that run off a surface in a matter of picoseconds.
LAWRENCE -- As climate change threatens the world, governments and organizations from around the globe have banded together to fight its effects. Yet that collaboration has not always carried over into the online world, where technology is often assumed to connect people and break down barriers. Research from the University of Kansas has found that nongovernment organizations, or NGOs, dedicated to fighting climate change from rich countries and certain parts of the globe are dominating the online conversation, leaving others at risk of being left out.
"When is my baby going home?" is one of the first questions asked by families of infants admitted to the neonatal intensive care unit (NICU). Now clinicians have a data-based answer. Moderate to late preterm babies (born at gestational age of 32 to 36 weeks) who have no significant medical problems on admission are likely to be discharged at 36 weeks of postmenstrual age (gestational age plus age since birth), according to a study published in the American Journal of Perinatology. Small for gestational age infants and those with specific diagnoses may stay longer.
Studies of animal movement and behavior--including those addressing disease spread and animal conservation--should monitor animals at both regular and irregular time points to improve understanding of animal movement behavior, according to a new study by Penn State statisticians. The study, which appears online this month in the journal Environmetrics, is the first to provide guidance about sampling regimes for these types of biological studies.
A 50-year-old puzzle in statistical mechanics has been solved by an international team of researchers who have proved that two-dimensional (2D) liquids have fundamentally different dynamical properties to three-dimensional (3D) liquids.
Researchers routinely use 2D experiments and simulations to represent 3D liquids, simply because studies in 2D are easier to do.
With these studies, physicists aim at rationalising familiar macroscopic fluid properties, such as the viscosity, in terms of the microscopic motion of the particles, which in 2D can be directly visualised.
(BOSTON)--Low-income parents reported lower perceived parenting stress and better overall outcomes when parents participated in Parenting Journey, a community-delivered curriculum designed to increase resilience and support nurturing family relationships.
While previous studies have identified the positive impact that parenting programs have on outcomes in both children and families, in 2016 the National Academy of Sciences highlighted the need for further research on these programs in diverse populations.
Acute myeloid leukemia (AML) is a deadly blood cancer that originates in the bone marrow and kills most of its victims within five years. Chemotherapy has been the standard AML treatment for over 40 years, and while it often causes the cancer to go into remission, it rarely completely eliminates the cancerous cells, which then lead to disease recurrence in nearly half of treated patients. Aggressive post-remission treatments, like high-dose chemotherapy or bone marrow transplants, can reduce the chance of recurrence, but many AML patients are not healthy enough to tolerate them.
New research from McGill University and the University of California, Santa Cruz has found that the local streets of the world's cities are becoming less connected, a global trend that is driving urban sprawl and discouraging the use of public transportation.
The essential roles that microbes play in deep-sea ecosystems are at risk from the potential environmental impacts of mining, a new paper in Limnology and Oceanography reports. The study reviews what is known about microbes in these environments and assesses how mining could impact their important environmental roles.
BUFFALO, N.Y. - He calls it his "chocolate and peanut butter moment."
A University at Buffalo neuroimaging researcher has developed a computer model of the human brain that more realistically simulates actual patterns of brain impairment than existing methods. The novel advancement represents the union of two established approaches to create a digital simulation environment that could help stroke victims and patients with other brain injuries by serving as a testing ground for hypotheses about specific neurological damage.
Hartford, CT - In a new analysis of studies conducted following the implementation of the 2010 Healthy Hunger Free Kids Act (HHFKA), researchers find positive effects on the dietary quality of meals served to school-aged children.
As several states draft legislation that would force student-athletes to play as their gender identified on their birth certificate instead of on a team that matches their gender identity, a team of political scientists investigated underlying factors that drive public opinion on transgender athletes.
Studies that started in zebrafish have now pointed to a role for collagen secretion in a wide variety of clinical symptoms -- and in a newly identified genetic syndrome.
Ela Knapik, MD, associate professor of Medicine at Vanderbilt University Medical Center, and her colleagues discovered the syndrome caused by mutation of a single gene and named it CATIFA, an acronym for its core symptoms: cleft palate, cataracts, tooth abnormality, intellectual disability, facial dysmorphism and ADHD.
In the quantum realm, under some circumstances and with the right interference patterns, light can pass through opaque media.
This feature of light is more than a mathematical trick; optical quantum memory, optical storage and other systems that depend on interactions of just a few photons at a time rely on the process, called electromagnetically induced transparency, also known as EIT.
What's your type?
That question could gain new meaning, thanks to scientists who've categorized how humans age into different classes dubbed "ageotypes," reports a new study from the Stanford University School of Medicine.
