From decades of astronomical observations scientists know that most galaxies contain massive black holes at their centers. The gas and dust falling into these black holes liberates an enormous amount of energy as a result of friction, forming luminous galactic cores, called quasars, that expel jets of energetic matter. These jets can be detected with radio telescopes up to large distances. In our local Universe these radio jets are not uncommon, with a small fraction being found in nearby galaxies, but they have remained elusive in the distant, early Universe until now.  Using a combination of telescopes, astronomers have discovered a distant, two-lobed radio ...

Our immune system is armed with an array of defenses designed to detect and eliminate harmful threats. One of its most powerful defense mechanisms is the complement system—a group of proteins that patrols our body, ever vigilant for signs of infection or injury. Now, over 100 years after the complement system was first described, researchers at Mass General Brigham have discovered that a protein known as granzyme K (GZMK) drives tissue damage and inflammation by activating the complement system against our own tissues. Their findings not only reshape the century-old understanding of the complement system but also open new avenues for therapies that could specifically ...

Alcohol use disorder, which affects over 10% of Americans, can lead to persistent and serious insomnia. Difficulties falling asleep and staying asleep can last even after months of sobriety, increasing the risk of relapse. But treating withdrawal-related insomnia is difficult, partly because what’s going on in the brain in this condition remains largely mysterious. Now, research in fruit flies has identified specific brain signals and groups of brain cells that are involved in alcohol-induced insomnia. This work could ultimately lead ...

Key Takeaways: Appalachia is not uniform: There are important distinctions in cancer diagnoses and deaths among different regions of Appalachia, with certain areas of Central Appalachia experiencing the highest rates of cancer incidence and deaths among the greater Appalachian region. Higher death rates from cancers that can be caught early with screening: Although the region has improved in screening rates, people in Appalachia still die more frequently from cancers that can be caught early with routine screening than elsewhere in the  United States. Reason for hope: Research can pave the way for targeted interventions that can reduce these ...

LOS ANGELES — Why do some people who consume a few glasses of alcohol a day develop advanced liver disease while others who drink the same amount don’t?   The answer may lie in three common underlying medical conditions, according to a new study published in Clinical Gastroenterology and Hepatology from Keck Medicine of USC. The research found that heavy drinkers with either diabetes, high blood pressure or a high waist circumference are as much as 2.4 times more likely to develop advanced liver disease.   “The results ...

The blue whale is the largest animal on the planet. It consumes enormous quantities of tiny, shrimp-like animals known as krill to support a body of up to 100 feet (30 meters) long. Blue whales and other baleen whales, which filter seawater through their mouths to feed on small marine life, once teemed in Earth’s oceans. Then over the past century they were hunted almost to extinction for their energy-dense blubber. As whales were decimated, some thought the krill would proliferate in predator-free waters. But that’s not what happened. Krill populations dropped, too, and neither population has ...

Fish is a high-quality source of protein, containing omega-3 fatty acids and many other beneficial nutrients. However, the accumulation of toxic mercury also makes fish consumption a concern, of which tuna is particularly susceptible. Researchers from Chalmers University of Technology in Sweden have come up with a novel approach to packaging canned tuna infused in the water-based solution of amino acid cysteine. It was shown to remove up to 35 percent of the accumulated mercury in canned tuna, significantly reducing human exposure to mercury via food. Fish and other seafood, provide people with a broad variety of essential nutrients in their diet However, the consumption ...

Searching for life in alien oceans may be more difficult than scientists previously thought, even when we can sample these extraterrestrial waters directly.  A new study focusing on Enceladus, a moon of Saturn that sprays its ocean water into space through cracks in its icy surface, shows that the physics of alien oceans could prevent evidence of deep-sea life from reaching places where we can detect it.  Published today (Thursday, 6 February 2025) in Communications Earth and Environment, the study shows how Enceladus's ocean forms distinct layers that dramatically slow the movement of material ...

A recent Brazilian study published in Nature Cardiovascular Research has highlighted promising pathways for preventing and treating atrial fibrillation, a condition that significantly raises the risks of stroke and dementia. The research was led by the Federal University of Rio de Janeiro (UFRJ) in partnership with the D’Or Institute for Research and Education (IDOR). What Is Atrial Fibrillation? Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide. It disrupts the normal rhythm of the heart, causing irregular and often rapid heartbeats. This condition is associated with increased risks of stroke, dementia, and heart failure. It is also linked to other health ...

How would you summarize your study for a lay audience? Heart failure remains a substantial burden for patients due to its high prevalence and limited therapeutic options. Heart failure is classified into two major clinical subtypes— heart failure with preserved ejection fraction (HFpEF) and heart failure with reduced ejection fraction (HFrEF). While there have been significant therapeutic advances in HFrEF, the rate of complications and death from HFrEF remains high. Additionally, most drugs that have shown benefits for patients with HFrEF have not demonstrated a comparable benefit in patients with HFpEF, highlighting a critical need for the development of targeted therapies ...

People’s ability to interpret emotions or focus on performing a task is reduced by short-term exposure to particulate matter (PM) air pollution, potentially making everyday activities, such as the weekly supermarket shop, more challenging, a new study reveals. Scientists discovered that even brief exposure to high concentrations of PM may impair a person’s ability to focus on tasks, avoid distractions, and behave in a socially acceptable manner. Researchers exposed study participants to either high levels of air pollution - using candle smoke - or clean air, testing cognitive abilities ...

Key points: Researchers from the Voigt lab have extended our understanding of how developmental genes are held in a poised state to allow timely expression once they receive the correct ‘go’ signals. The next layer of regulation has been uncovered by the identification of proteins that interact with the epigenetic marks that poise developmental genes ready for expression. The research provides insight into the mechanisms through which the phenomenon of bivalency – where both activating and repressive marks are laid down at the same site on the genome – acts to ready developmental ...
