Air pollution and cardiac remodeling and function in patients with breast cancer

JAMA Network Open

2026-01-15

(Press-News.org) About The Study: In this cohort study, fine particulate matter (PM2.5) and ozone exposure was independently associated with worse cardiac remodeling and function in patients with breast cancer treated with cardiotoxic therapy. These findings highlight the importance of modifying environmental exposures to mitigate cardiovascular disease risk.

Risk of suicide in patients with traumatic injuries

2026-01-15

About The Study: In this cohort study of patients in Norway discharged alive after critical injury, a 9-fold increased risk of suicide after 2 years was observed. These findings suggest that follow-up is warranted for possible psychological distress in this patient group.

The Frontiers of Knowledge Award goes to Allan MacDonald and Pablo Jarillo-Herrero for their discovery of the “magic angle” enabling science to transform and control the behavior of new materials

2026-01-15

In his theoretical model published in 2011, Canadian Allan MacDonald predicted that by twisting two graphene layers at a given angle, in the region of one degree, the interaction of electrons would produce new emerging properties. Seven years later, Spaniard Jarillo-Herrero and his team provided the experimental confirmation, fabricating bilayers of graphene rotated at this “magic angle” that transformed the material’s behavior, giving rise to new properties like superconductivity. “Their work has opened up new frontiers in physics by demonstrating that rotating matter to a given angle allows us to control its behavior, obtaining ...

Discovery reveals how keto diet can prevent seizures when drugs fail

2026-01-15

University of Virginia School of Medicine researchers have revealed how the popular, low-carb ketogenic diet protects against epilepsy seizures and possibly neurodegenerative diseases such as Alzheimer’s and Parkinson’s. Keto, as the diet is commonly known, has been used to reduce seizures in patients with medication-resistant epilepsy since the 1920s. Doctors, however, have been uncertain exactly how the diet does this, even as they identified potential benefits for other brain disorders. A team led by UVA’s Jaideep Kapur, MBBS, PhD, co-director of UVA’s Brain Institute, has found answers. This discovery could ...

University College of Molde (Høgskolen i Molde) is the first institution to join the trial program. “Our partnership with Sikt is further progress in our mission to advance open science and empower researchers globally,” said Dennis O’Brien, VP ...

Finding new cell markers to track the most aggressive breast cancer in blood

2026-01-15

Of all the types of breast cancer, triple negative breast cancer (TNBC) is the most aggressive and lacks specific therapies. TNBC also is more likely to metastasize, or travel through the blood stream to spread to other organs, which causes most of breast cancer-related deaths each year. Until now, tracking circulating tumor cells (CTC), a powerful indicator of cancer metastasis, has been challenging because there are very few markers that specifically identify these cells. Looking to find a better way to follow metastasis progression, researchers at Baylor College of Medicine developed a procedure to enhance the ...

A new, cleaner way to make this common fertilizer

2026-01-15

The last time you scrubbed a streaky window or polished a porcelain appliance, you probably used a chemical called ammonia. Also known as ammonium hydroxide when mixed with water, ammonia is more than a common household cleaner. More than 170 million metric tons of it are produced globally every year, with most of it ending up as fertilizer for corn, cotton and soybeans. UIC researchers are scaling up a system for farmers to produce ammonia in their own backyards. The method, which uses renewable electricity and Earth’s natural resources, appears in the journal PNAS. “So many people around the world need food. ...

Fire-safe all-solid-state batteries move closer to commercialization

2026-01-15

The Korea Research Institute of Standards and Science (KRISS, President Lee Ho Seong) has developed a key materials technology that accelerates the commercialization of all-solid-state batteries (ASSBs)—next-generation batteries designed to intrinsically eliminate the risks of fire and explosion. The Emerging Material Metrology Group at KRISS demonstrated ultra-dense, large-area solid electrolyte membranes by applying a method that coats solid electrolyte powders with multifunctional compounds, reducing production costs to one-tenth of conventional levels. Lithium-ion secondary batteries, which are widely used in electric vehicles ...

Disinfecting drinking water produces potentially toxic byproducts — new AI model is helping to identify them

2026-01-15

Hoboken, NJ., January 12, 2026 — Disinfecting drinking water prevents the spread of deadly waterborne diseases by killing infectious agents such as bacteria, viruses and parasites. Without disinfection, even clear-looking water can carry pathogens that can cause severe and even life-threatening illness, especially in children, older adults, and people with weakened immune systems. Before water disinfection processes were put in place, outbreaks of waterborne diseases such as cholera, typhoid, and dysentery routinely claimed lives, decimating cities and even countries. Disinfecting drinking water is ...
