Tech Xplore / Shifting data center power to off-peak hours could cut grid costs in the age of AI
The number of U.S. data centers is growing, largely to power artificial intelligence programs. That has led to concern about the environmental consequences of data centers—and their impact on the energy grid itself. What ...
Medical Xpress / Blood vessel cells keep fixed signaling roles for weeks, reshaping view of capillary communication
The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood flow, sense physical forces and keep vessel walls intact. Scientists have known about this signaling ...
Phys.org / Novel crystal strategy delivers near-perfect zero thermal expansion from 11 K to 893 K
Almost every material expands when heated. Well-known examples include railroad tracks and concrete roadways, which feature visible expansion gaps to accommodate this effect. However, thermal expansion poses a far more acute ...
Phys.org / Rising heat and humidity challenge energy-efficient data center cooling worldwide
Reliable operation of data centers has become essential to nearly all sectors of modern society, including health care, education, government services, power grid operation, banking, defense and disaster relief. New research ...
Phys.org / May 2024 superstorm drew most ring current ions from Earth, not solar wind, research reveals
In May 2024, auroras were observed at unusually low latitudes across the globe, lighting up skies that rarely see such displays. Inside Earth's magnetosphere, the region of space surrounding our planet and dominated by its ...
Medical Xpress / Breastfeeding may protect against ADHD symptoms
A new study from the University of Bergen shows an association between breastfeeding up to 6 months of age and a reduced risk of ADHD symptoms from ages 3 to 8.
Medical Xpress / Prevalence of right ventricular dysfunction ~40% in heart failure with preserved ejection fraction
Right ventricular dysfunction (RVD) is prevalent in 41.7% of patients with heart failure with preserved ejection fraction (HFpEF), according to a study published online June 10 in BMC Cardiovascular Disorders.
Phys.org / Far-red radiation and elevated CO₂ boost biomass accumulation in young leaf lettuce indoors
A new study from scientists at Purdue University reports that far-red radiation, in combination with increased carbon dioxide (CO₂) concentration, significantly enhances biomass production in young leaf lettuce grown under ...
Phys.org / Three ways climate action can be more inclusive for 1.3 billion disabled people
Imagine a global political summit that shapes the future of our planet, where one of the most populous countries in the world does not have a voice. This may seem unlikely, but currently 1.3 billion disabled people (nearly ...
Phys.org / How coworkers shape careers: Learning and competition pull in opposite directions
New research, published by the Rockwool Foundation Berlin (RFBerlin), shows that co-workers can have powerful—but opposing—effects on the careers of young workers. While some colleagues foster learning and long-term success, ...
Phys.org / An iron-driven chain reaction may trigger mass death of harmful algae blooms
Over recent decades, harmful algal blooms have become increasingly common. These blooms often consist of bacteria called "cyanobacteria" in freshwater ecosystems. They can produce debilitating toxins, suffocate marine life ...
Medical Xpress / AI support tool improves clinician decisions in real-world primary care trial
A large real-world clinical trial has found that a generative AI-powered support tool used to support frontline clinicians was safe and improved the quality of clinical decision-making, but did not significantly change short-term ...
