Handling salty brines from CO₂ storage presents a major energy and emissions hurdle. Optimizing brine disposal and reservoir choices will be critical for the success of carbon capture strategies. Perhaps the best hope for slowing climate change — capturing and storing carbon dioxide emissions underg...

New open-shell carbon rings reveal how subtle molecular tweaks impact spin states and stability Chemical rings of carbon and hydrogen atoms curve to form relatively stable structures capable of conducting electricity and more — but how do these curved systems change when new components are introduce...

New scientific dating shows Machu Picchu predates historic records by decades, revealing the Inca empire’s early expansion. Machu Picchu, the famous 15th-century Inca site in southern Peru, is up to several decades older than previously thought, according to a new study led by Yale archaeologist Ric...

First U.S. study to show lower cardiac risk of cardiac events in patients following SARS-CoV-2 infection. Analyzing the most extensive datasets in the United States, researchers from the Icahn School of Medicine at Mount Sinai have revealed that vaccination against COVID-19 is associated with fewer ...

Popular Weight–Loss Diet Also Associated With Higher Levels of LDL Cholesterol The ketogenic or “keto” diet, which involves consuming very low amounts of carbohydrates and high amounts of fats, has been gaining popularity. However, a new study ...

A pilot project has estimated emissions and removals of carbon dioxide in individual nations using satellite measurements. A NASA Earth-observing satellite has helped researchers track carbon dioxide emissions for more than 100 countries around the world. The pilot project offers a powerful new look...

Findings show monthly vitamin D may prevent heart attacks in over 60s. Vitamin D supplements may reduce the risk of major cardiovascular events such as heart attacks among people aged over 60, finds a clinical trial published on June 28 by The BMJ. The researchers stress that the absolute risk diffe...

Diet score derived from ongoing, large-scale global Prospective Urban and Rural Epidemiological (PURE) study. A study spearheaded by McMaster University and Hamilton Health Sciences researchers at the Population Research Health Institute (PHRI) has found that not eating enough of six key foods in co...

Connected Vehicles Improve Traffic Flow, While Automated Vehicles Slow It Down A recent study reveals that vehicles that wirelessly communicate with each other, known as “connected” vehicles, considerably enhance the flow of traffic at intersections. However, automated vehicles that don&...

Cannabis Use Disorder May Be Linked to Increased Risk of Cardiovascular Disease A new study has discovered that Canadian adults with cannabis use disorder appear to have an approximately 60% higher risk of experiencing their first heart attack, stroke, or other major cardiovascular event than those ...

A massive study sharpens the outlook on greenhouse gases and climate. A massive new review of ancient atmospheric carbon dioxide levels and corresponding temperatures lays out a daunting picture of where the Earth’s climate may be headed. The study covers geologic records spanning the past 66 millio...

Making one small diet change — chicken instead of beef, plant milk instead of cow’s milk — could significantly curb carbon emissions and increase the healthfulness of your diet. Curbing carbon emissions and eating healthier may both start at the dinner table. According to a new study co-author...

Mangroves and salt marshes capture significant quantities of carbon, thereby reducing the greenhouse effect. New research from the University of Gothenburg shows that these environments are perhaps twice as effective as previously thought. Natural habitats flooded by the tide form ecosystems that ca...

A study reveals that personal vehicle interiors are contaminated with cancer-linked flame retardants due to outdated flammability standards. These chemicals, found in 99% of tested cars, pose significant health risks, especially in warm conditions which increase their concentration. The air inside a...

New research investigated the risks associated with energy drink consumption using data from a cohort of sudden cardiac arrest survivors at the Mayo Clinic. A recent study published in Heart Rhythm, the official journal of the Heart Rhythm Society, the Cardiac Electrophysiology Society, and the Pedi...

Research updates radiocarbon calibration curve and reevaluates dates of Greek shipwrecks. Improved radiocarbon calibration techniques now offer more accurate date estimates for Greek shipwrecks, according to a study published in the open-access journal PLOS ONE by Sturt Manning of Cornell University...

In 2023, Canada experienced its warmest and driest conditions in decades, leading to extreme forest fires that released approximately 640 million metric tons of carbon, akin to the annual emissions of a major industrialized nation. This study, conducted by NASA using satellite data and advanced comp...

Research indicates that COVID-19 survivors face doubled risks of severe cardiac events for years after recovery, especially if hospitalized. People with A, B, or AB blood types are particularly vulnerable, highlighting the need for personalized approaches to heart health post-COVID. COVID-19 and Car...

Astronaut photos reveal the dramatic transformation of Madagascar’s largest estuary, the Betsiboka, over decades. Deforestation and agriculture have caused severe erosion, changing the delta’s landscape, forming new islands, and expanding mangroves significantly since 1984. An astronaut ...

Terrestrial carbon sinks grew by 30% from 1992 to 2019, with most carbon stored in nonliving pools, not forests, prompting a call to update climate models. Recent studies have shown that carbon stocks in terrestrial ecosystems are increasing, helping to offset about 30 percent of the carbon dioxide ...

A groundbreaking study identifies the most influential modifiable non-clinical risk factors for enhancing heart health. A new study has identified 56 non-clinical risk factors associated with sudden cardiac arrest (SCA), encompassing lifestyle behaviors, physical characteristics, psychosocial influe...

Researchers have determined that the large-scale adoption of technologies designed to capture carbon dioxide from industrial emissions and the atmosphere would be significantly more costly and environmentally harmful than a global transition to renewable energy sources for electricity and heating. S...

The findings support the recommendation to minimize added sugars in the diets of pregnant women and infants. A new study published in The BMJ has found that limiting sugar intake during early life is associated with a reduced likelihood of developing major heart conditions later on, including heart ...
