Gut Microbial Pathway identified as Target for Improved Heart Disease Treatment

Posted by in category: biotech/medical

Cleveland Clinic researchers have made a significant discovery about how the gut microbiome interacts with cells to cause cardiovascular disease. The study published in Nature Communications found that phenylacetylglutamine (PAG), produced by gut bacteria as a waste product, then absorbed and formed in the liver, interacts with previously undiscovered locations on beta-2 adrenergic receptors on heart cells once it enters the circulation.

PAG was shown to interact with beta-2 adrenergic receptors to influence how forcefully the heart muscle cells contract—a process that investigators believe contributes to heart failure. Researchers showed mutating parts of the beta-2 adrenergic receptor that were previously thought to be unrelated to signaling activity in preclinical models prevented PAG from depressing the function of the receptor.

This is the latest in a series of investigations into PAG, led by Stanley Hazen, MD, Ph.D., chair of Cardiovascular and Metabolic Sciences in Cleveland Clinic’s Lerner Research Institute and co-section head of Preventive Cardiology. Dr. Hazen’s lab previously demonstrated that elevated circulating levels of PAG in subjects are associated with heightened risk for developing heart failure, and lead to worse outcomes for patients with heart failure.

Australia Green Lights World’s ‘Largest’ Solar Hub

Posted by in categories: energy, food, sustainability

Australia on Wednesday approved plans for a massive solar and battery farm that would export energy to Singapore, a project it calls the “largest solar precinct in the world”

Authorities announced environmental approvals for SunCable’s US$24 billion project in Australia’s remote north that is slated to power 3million homes.

The project, which will include an array of panels, batteries and, eventually, a cable linking Australia with Singapore, is backed by tech billionaire and green activist Mike Cannon-Brookes.

Something very strange is happening in the early universe and scientists have no clue why their theories are failing to explain these strange mysteries. Scientists are finding thousands of strange objects in deep field images and they have no idea what exactly they are looking at. They discovered many strange objects in the early universe and scientists said that they cannot be galaxies because these objects are completely different compared to early galaxies. In addition, the Webb telescope looked deep into the universe beyond the Dark Ages for the first time, and what it found has astonished astronomers.
Most scientists agree that the universe began about 13.8 billion years ago. However, the strange structures revealed in these images challenge this timeline and could lead to major shifts in cosmology, the study of the universe’s origin and development.

Universal Bound on Effective Central Charge and Its Saturation

Posted by in category: energy

The effective central charge (denoted by c_eff) is a measure of entanglement through a conformal interface, while the transmission coefficient (encoded in the coefficient c_LR$ of the two-point function of the energy-momentum tensor across the interface) is a measure of energy transmission through the interface. It has been pointed out that these two are generally different. In this Letter, we propose the inequalities, $0lec_LRlec_efflemin(c_L,c_R). They have the simple but important implication that the amount of energy transmission can never exceed the amount of information transmission. We verify them using the AdS/CFT correspondence, using the perturbation method, and in examples beyond holography.

China to build first thorium molten salt NPP in Gobi Desert

Posted by in category: nuclear energy

China has announced the construction of a nuclear power plant that will be fuelled by liquid fuel based on molten thorium salt. The Shanghai Institute of Applied Physics (SINAP) has been engaged in research in this area since 2011 focusing on liquid fluoride-thorium reactors (LFTRs). The construction of a prototype of a thorium molten salt reactor (TMSR) with a capacity of 2 MW began in September 2018 and was reportedly completed in August 2021. China is seeking to get full intellectual property rights to this technology.

Now China plans to build the world’s first NPP based on molten salt in the Gobi desert. Construction will begin in 2025 with the aim of developing safer and more environmentally friendly nuclear energy. The reactor does not need water for cooling, since it uses liquid salt and carbon dioxide to transfer heat and generate electricity.

In 2022, SINAP received permission from the Ministry of Ecology and Environmental Protection to commission an experimental MTSR. This is the first nuclear molten salt reactor since the United States stopped its molten salt test reactor in 1969. The application for the operation of the experimental reactor was considered in China in June 2023, it was considered to be fully compliant with safety requirements.

AIs generate more novel and exciting research ideas than human experts

Posted by in categories: innovation, robotics/AI

The first statistically significant results are in: not only can Large Language Model (LLM) AIs generate new expert-level scientific research ideas, but their ideas are more original and exciting than the best of ours – as judged by human experts.

Recent breakthroughs in large language models (LLMs) have excited researchers about the potential to revolutionize scientific discovery, with models like ChatGPT and Anthropic’s Claude showing an ability to autonomously generate and validate new research ideas.

This, of course, was one of the many things most people assumed AIs could never take over from humans; the ability to generate new knowledge and make new scientific discoveries, as opposed to stitching together existing knowledge from their training data.

Research finds sex-based differences in how brains handle threats

Posted by in categories: biotech/medical, health, neuroscience, sex

A new study has uncovered significant differences in how male and female mice process threats, even as they exhibit similar behavioural responses. The discovery suggests that including both male and female subjects in neuroscience research will lead to more accurate conclusions and ultimately better health outcomes. Understanding the influence of sex on brain function can help explain why males and females develop certain psychiatric disorders at different rates or with different symptoms, the researchers said. ‘Unless we thoughtfully and rigorously integrate sex into biomedical research, a huge amount of the population may be underserved by scientific knowledge,’ said McGill University Associate Professor and Canada Research Chair in Behavioural Neurogenomics Rosemary Bagot, who led the study. ‘Our work shows that sex is an important variable to consider, even if initial observations don’t necessarily show clear sex differences,” said Bagot. “If males and females are using different brain circuits to solve similar problems, they may be differently vulnerable to stress and respond differently to treatments.’ How brain circuits process threats and cues The study focused on two related brain circuits and their roles in processing information about threats and the cues that predict them. The researchers trained mice to recognize a sound that signalled a threat and another sound that meant safety. By observing brain activity, the team saw how communication between different brain areas processed these signals. Then, they temporarily turned off each brain connection to see how it affected the mice’s reactions, helping them understand how the brain handles threats. ‘We found that even though male and female mice respond similarly to threats, the brain circuits underlying these responses are not the same,’ Bagot said. For female mice, a connection between two specific brain areas (the medial prefrontal cortex and the nucleus accumbens) played a key role. The study found that in male mice, a different connection (between the ventral hippocampus and the nucleus accumbens) was more important for handling the same situation. It was previously assumed that similar behavior meant similar brain function. Now, the researchers are exploring how sex impacts brain circuits in processing threats, focusing on the role of sex hormones and different learning strategies. This research is supported by funding from CIHR. About the study Sex-biased neural encoding of threat discrimination in nucleus accumbens afferents drives suppression of reward behavior by Jessie Muir, Eshaan Iyer et al., was published in Nature Neuroscience.
