Although the material damage from 2012's Hurricane Sandy may have been repaired, the storm left a lasting impact on cardiovascular health, according to new findings from Weill Cornell Medicine and New York University researchers. The study, published Sept. 3 in JAMA Network Open, found that older adults living in flood-hit areas in New Jersey faced a 5% higher risk of heart disease for up to five years after Sandy’s landfall. This is one of the first studies to rigorously quantify long-term cardiovascular risks associated with flooding in older adults. Most studies focus ...

Researchers at The Hospital for Sick Children (SickKids) have uncovered a promising new therapeutic target for Barth syndrome, a rare genetic condition with no current cure.  Barth syndrome is an X-linked genetic condition affecting about 500 people worldwide, most of whom are males. The rare condition causes muscle weakness, frequent infections and cardiomyopathy. While heart transplants can manage cardiac symptoms, many children with Barth syndrome do not live past early childhood.  The research, published in Nature, was an international effort involving academic and industry collaborations, and revealed ...

A research team led by Nanjing University has introduced a transparent, colorless, and unidirectional solar concentrator that can be directly coated onto standard window glass. Utilizing cholesteric liquid crystal (CLC) multilayers with submicron lateral periodicities, this diffractive-type solar concentrator (CUSC) selectively guides sunlight toward the edge of the window where photovoltaic cells are installed. The study appears in PhotoniX. Unlike conventional luminescent or scattering-based concentrators, which often suffer ...

Microplastics are tiny, plastic fragments — many too small to see — found in the air, soil and water. Measuring their abundance in nature can direct cleanup resources, but current detection methods are slow, expensive or highly technical. Now, researchers publishing in ACS Sensors have developed a living sensor that attaches to plastic and produces green fluorescence. In an initial test on real-world water samples, the biosensor could easily detect environmentally relevant levels of microplastics. Currently, scientists detect ...

Brain–computer interfaces are technologies that enable direct communication between brain activity and external devices, enabling researchers to monitor and interpret brain signals in real time. These connections often involve arrays of tiny, hair-like electrodes called “microelectrodes” which are implanted within the brain to record or stimulate electrical activity. For decades, microelectrodes have faced a challenge in balancing conductivity with tissue compatibility. Rigid metal or silicon-based electrodes enable stable signal recordings but often damage the delicate brain tissues, whereas softer polymer electrodes reduce harm but suffer from poor signal transmission. Bridging ...

Bipolar disorder (BD) is a chronic mental health condition characterized by recurrent episodes of depression and mania. It poses a substantial burden on global health, with an increasing incidence. Despite its prevalence, there exists a significant gap in understanding the underlying neuropathological mechanisms. Although mitochondrial dysfunction has been implicated in BD, the specific brain region damaged is not yet fully understood. A deeper understanding is essential for advancing research efforts and developing ...

Polyamines, a group of naturally occurring molecules found in all living organisms, are essential for fundamental cellular processes, such as growth and differentiation. In recent years, these compounds (particularly spermidine) have gained attention as promising ‘geroprotectors’ that promote healthy aging and extend lifespan. Studies have shown that polyamines can activate beneficial cellular processes like autophagy, which helps clear damaged cell components, primarily through a protein called eukaryotic translation initiation factor 5A (eIF5A1). However, these positive effects are overshadowed by a troubling paradox, as elevated polyamine levels are also consistently ...

New research from Michigan State University reveals that photorespiration – long considered a wasteful process – is essential for producing a crucial nutrient for preventing birth defects. For the first time, scientists have measured how much carbon flows through photorespiration to make folates, a class of compounds that includes vitamin B9 – known for its importance as a prenatal vitamin. According to the study, led by MSU researcher Berkley Walker, about 6 percent of the carbon absorbed by plants is used to make folates. That number plummets by fivefold when photorespiration is suppressed.   These findings, published in Nature Plants, could help scientists engineer ...

A team of scientists at Kyoto University’s Institute for Integrated Cell-Material Sciences (iCeMS) has created a protein-based therapeutic tool  that could change the way we treat diseases caused by harmful or unnecessary cells. The new tool, published in Nature Biomedical Engineering, involves a synthetic protein called Crunch, short for Connector for Removal of Unwanted Cell Habitat. Crunch uses the body’s natural waste removal system to clear out specific target cells, offering hope for improved treatments for cancer, autoimmune diseases, and other diseases where harmful cells cause damage. Every day, billions of our body’s ...

Osaka, Japan – The nostalgic “glow-in-the-dark” stars that twinkle on the ceilings of childhood bedrooms operate on a phenomenon called phosphorescence. Here, a material absorbs energy and later releases it in the form of light. However, recent demand for softer, phosphorescent materials has presented researchers with a unique challenge, as producing organic liquids with efficient phosphorescence at room temperature is considered difficult. Now, researchers at The University of Osaka have attempted to tackle this problem by producing an organic liquid that phosphoresces in the ambient environment. ...

Climate action is falling behind on the goals as stated in the Paris Agreement. To meet those goals, countries must act according to their ‘fair share’ targets. However, researchers from Utrecht University found a bias in how ambition and fairness assessments were calculated until now: “previous studies assessing countries climate ambition share a feature that rewards high emitters at the expense of the most vulnerable ones.” This finding influences climate change mitigations globally. The research, led by Yann Robiou du Pont, was published on 3 September in Nature Communications. The ...

The world’s methane emissions continue to rise steadily with no signs of slowing, as global trade contributes some 30% to the total amount of the greenhouse gas swirling around the planet, a new study reveals. As major trade patterns shift, South-South transactions now dominate global supply chains with developing countries increasingly participating in global supply chains. Asia and the developing Pacific region emerge as the largest contributors to global methane emissions, driven by rapid industrialisation and population growth. Publishing their research today (3 Sep) in Nature Communications, an international team led by researchers at the Universities of Birmingham ...

A study in Health Economics reveals that comprehensive state bans on flavored e-cigarettes may reduce vaping among young adults, but they can also lead to increased use of traditional cigarettes. Using information from national datasets and advanced statistical methods, researchers found evidence that young adults 18–24 years of age decrease their use of e-cigarettes by about 2–3 percentage points after state bans, while increasing traditional cigarette use by a similar amount. Because cigarettes are more dangerous to health than e-cigarettes, there appears to be a net negative effect on health for this age group. For youth ...

Research in Economic Inquiry reveals that Major League Baseball teams appear to manage player injuries differently depending on contract status, with players on temporary contracts missing significantly fewer games due to injury. This suggests that teams may invest less in the long-term health of non-permanent players. For the study, investigators analyzed 2009–2017 data, with 4,125 observations for 1,184 unique players, so that the average player had available data for approximately 3.5 years. The findings raise ...
