In 1982, the Syrian government besieged the city of Hama, killing tens of thousands of its own citizens in sectarian violence. Four decades later, rebels used the memory of the massacre to help inspire the toppling of the Assad family that had overseen the operation. But there is another lasting effect of the attack, hidden deep in the genes of Syrian families. The grandchildren of women who were pregnant during the siege — grandchildren who never experienced such violence themselves — nonetheless bear marks of it in their genomes. ...

When faced with chronic stress, why do some people develop anxiety and depressive symptoms while others show resilience? A protein that acts as a cannabinoid receptor and is present in the structure controlling exchanges between the bloodstream and the brain could be part of the answer, according to a study published today in Nature Neuroscience. “The protein, called cannabinoid receptor type 1 (CB1), is part of the blood-brain barrier, the dynamic structure that protects the brain by regulating the passage of molecules between the bloodstream and ...

The results are published in Nature Neuroscience. “Traumatic brain injury is a leading cause of death and disability — including cognitive decline ...

Covid-19 showed us how vulnerable the world is to pandemics – but what if the next pandemic were somehow engineered? How would the world respond – and could we stop it happening in the first place? These are some of the questions being addressed by a new initiative launched today at the University of Cambridge, which seeks to address the urgent challenge of managing the risks of future engineered pandemics. The Engineered Pandemics Risk Management Programme aims to understand the social and biological factors that might drive an engineered pandemic and to make a major contribution ...

The researchers challenge the widespread belief that AI-induced bias is a technical flaw, arguing instead AI is deeply influenced by societal power dynamics. It learns from historical data shaped by human biases ,absorbing and perpetuating discrimination in the process. This means that, rather than creating inequality, AI reproduces and reinforces it. “Our  study highlights real-world examples where AI has reinforced existing biases.” Prof. Bircan says. “One striking case is Amazon’s AI-driven hiring tool, which was found to favor male candidates, ultimately reinforcing gender disparities in the job market. Similarly, government AI fraud detection ...

As different as they may seem, humans and cats have similar ailments, but in terms of health care, veterinary regenerative medicine is not as advanced. A possible solution rests in embryonic stem cells, which can differentiate into various types of cells and be transplanted to restore internal damage. Further, they are characterized by their near-natural state similar to induced pluripotent stem (iPS) cells. Recent research has successfully generated feline iPS cells, but not embryonic stem cells, so research on these cell lines is essential to improve the quality ...

Alcoholic and non-alcoholic fatty liver disease (NAFLD) are well-known risk factors for colorectal cancer (CRC). NAFLD has emerged as a heterogenous disease tightly linked to metabolic dysfunction and has been redefined under the umbrella term ‘steatotic liver disease’ (SLD). However, CRC risk variations across different SLD subgroups remain unknown. Now, researchers from Japan have discovered that the risk of CRC varies significantly among SLD subgroups, with patients with alcoholic liver disease being at higher risk. Lifestyle-related disorders have become increasingly prevalent, representing a major health ...

Chiral-structural-color materials produce color through microscopic structures that interact with light rather than through pigmentation or dyes. Some beetle exoskeletons, avian feathers, butterfly wings, and marine organisms feature these structures naturally, producing iridescent or polarization-dependent colors. Over the last 10–15 years, scientists have made progress in developing artificial chiral-structural-color materials.  Recently, Chinese researchers have made a breakthrough in the field by discovering that microdomes made from common polymers exhibit tunable chiral structural colors with broad-spectrum capabilities and multiple ...

Cardiovascular diseases remain a leading cause of death worldwide, with platelet hyperactivity and subsequent thrombosis playing a pivotal role in these conditions. While intermittent fasting has long been recognized for its metabolic benefits, including improvements in metabolic diseases, weight loss, and even lifespan extension, its effect on platelet activation and thrombosis formation remains less understood.   A recent study by Professor Junbo Ge team at Fudan University unveiled a novel mechanism by which intermittent fasting can significantly reduce the risk of platelet hyperactivity and thrombosis. That is, intermittent fasting elevates levels of the metabolite ...

A team of scientists at UNSW has discovered that some of the most important new refrigerants break down, in part, into persistent greenhouse gas pollutants, including compounds that have been banned internationally. Refrigerants are chemicals that turn from a liquid to a gas – and vice-versa – and transfer heat in the process, that are used for refrigeration and indoor heating and cooling. The chemicals are also used as aerosol propellants, fire retardants and in the manufacture of foamed plastics. Hydrofluoroolefins (HFOs), which react rapidly in the lower atmosphere, have emerged as the lead synthetic chemical for refrigerants, and are considered a more environmentally friendly ...

In soil, nitrogen (N), an essential macronutrient for plant growth, exhibits significant spatial heterogeneity. This necessitates plants to grapple with a complex array of environmental conditions in their quest for N sustenance. Roots, as the pivotal organs in N acquisition, manifest a remarkable morphological plasticity, including variations in the length and density of primary roots, lateral roots, and root hairs, in response to the form and content of available N, which is termed N-dependent root system architecture (RSA). For cultivated crops, the ...

What if a critical piece of the puzzle of brain aging has been hiding in plain sight? While neuroscience has long focused on proteins and DNA, a team of Stanford researchers dared to shift their gaze to sugars – specifically the complex sugar chains that cover all our cells like chain mail. Their investigation revealed how changes in this sugary armor on the brain’s frontline cells could be key to understanding cognitive decline and diseases like Alzheimer’s. “This is like landing on a new planet,” ...

ITHACA, N.Y. – Leveraging national surveys, big data, and machine learning, Cornell University researchers have developed a new approach to mapping poverty that could help policymakers and NGOs better identify the neediest populations in poor countries and allocate resources more effectively. To eliminate extreme poverty, defined as surviving on less than $2.15 per person per day, governments and development and humanitarian agencies need to know how many people live under that threshold, and where. Yet that information ...

They may both be Olympic host cities, but Salt Lake City and Los Angeles, the major population hubs of their respective states, are much different places. However, they both experience poor air quality and share valley topography that traps pollutants during weather inversions. Utah and Southern California differ sharply in their approaches to this problem, with the latter implementing more stringent regulations and fuel standards aimed at reducing emissions from motor vehicles. New research from the University ...
