Ancient texts warn of love turning into hatred, as seen in stories like Cain and Abel or “Et tu, Brute?” This talk explores the neurobiology of hatred based on the biology of love: the oxytocin system, attachment networks, and biobehavioral synchrony, which mature through mother-infant bonding and later support group solidarity and out-group hostility. Using this model, we developed Tools of Dialogue© for Israeli and Palestinian youth. After 8 sessions, participants showed reduced hostility, increased empathy, hormonal changes (lower cortisol, higher oxytocin), and lasting attitudes of compromise. Seven years later, these changes supported their peacebuilding efforts, showing how social synchrony can transform hatred into reciprocity and cooperation. Recorded on 02/14/2025. [Show ID: 40386]

Research shows a high-magnesium diet could slow brain aging and lower dementia risk.

A study from the Australian National University shows that increased magnesium intake may help protect against age-related brain decline, particularly benefiting women.

Researchers analyzed data from over 6,000 participants aged 40–73, tracking their dietary magnesium consumption and its effects on brain volume and white matter lesions. Those consuming more than 550 mg of magnesium daily had brains appearing nearly a year younger by age 55 compared to those with lower intake.

The study also found that postmenopausal women experienced the greatest neuroprotective benefits, possibly due to magnesium’s anti-inflammatory properties.

Magnesium, found in foods like leafy greens, nuts, seeds, legumes, and whole grains, has long been known for its health benefits, but this research highlights its potential role in dementia prevention. With no cure for dementia, experts stress the importance of dietary strategies for brain health.

Forever chemicals affect your genes, according to a recent study.

Scientists have identified 11 genes that are consistently impacted by exposure to harmful chemicals that are found in everything from drinking water to food packaging.

Forever chemicals, also known as PFAS, are a global health concern. PFAS or “per-and poly-fluorinated alkyl substances” are also found in common household objects such as non-stick pans, stain or water-resistant materials as well as paints, carpets and clothes.

They are persistent in the environment and can accumulate in our bodies over time. They have been linked to a range of negative health outcomes, including impacting our genes. Some of the 11 genes that were impacted by PFAS are vital for neuronal health, and they showed altered expression levels after exposure to PFAS compounds. This discovery suggests these genes could serve as potential markers for detecting and monitoring PFAS-induced neurotoxicity.

However, the study also revealed that hundreds of other genes responded differently depending on the exact PFAS compound. While PFAS are known to accumulate in the brain due to their ability to cross the blood-brain barrier, this research provides new insights into the intricate ways these chemicals can interfere with gene expression and potentially disrupt our health. Concerns about PFAS stem from their potential health effects, which may include immune deficiency, liver cancer, and thyroid abnormalities. Due to their persistence and potential health risks, many governments are taking steps to regulate or ban the use of PFAS in various products.

A team of scientists from Nanyang Technological University, Singapore (NTU Singapore) has developed an artificial ‘worm gut’ to break down plastics, offering hope for a nature-inspired method to tackle the global plastic pollution problem.

By feeding worms with plastics and cultivating microbes found in their guts, researchers from NTU’s School of Civil and Environmental Engineering (CEE) and Singapore Centre for Environmental Life Sciences Engineering (SCELSE) have demonstrated a new method to accelerate plastic biodegradation.

Previous studies have shown that Zophobas atratus worms – the larvae of the darkling beetle commonly sold as pet food and known as ‘superworms’ for their nutritional value – can survive on a diet of plastic because its gut contains bacteria capable of breaking down common types of plastic. However, their use in plastics processing has been impractical due to the slow rate of feeding and worm maintenance.

Humanity can farm more food from the seas to help feed the planet while shrinking mariculture’s negative impacts on biodiversity, according to new research led by the University of Michigan.

There is a catch, though: We need to be strategic about it.

The findings are published in the journal Nature Ecology & Evolution.

Placazoa like seem simple at first — a crawling sheet of cells. Yet on closer examination, they show remarkable complexity and startling capabilities!

(https://en.wikipedia.org/wiki/Trichoplax)

adhaerens is one of the four named species in the phylum Placozoa. The others are Hoilungia hongkongensis, Polyplacotoma mediterranea and Cladtertia collaboinventa. Placozoa is a basal group of multicellular animals, possible relatives of Cnidaria. [ 2 ] are very flat organisms commonly less than 4 mm in diameter, [ 3 ] lacking any organs or internal structures. They have two cellular layers: the top epitheloid layer is made of ciliated “cover cells” flattened toward the outside of the organism, and the bottom layer is made up of cylinder cells that possess cilia used in locomotion, and gland cells that lack cilia. [ 4 ] Between these layers is the fibre syncytium, a liquid-filled cavity strutted open by star-like fibres.

Trichoplax feed by absorbing food particles—mainly microbes —with their underside. They generally reproduce asexually, by dividing or budding, but can also reproduce sexually. Though has a small genome in comparison to other animals, nearly 87% of its 11,514 predicted protein-coding genes are identifiably similar to known genes in other animals.

Everyone is talking about AI. Do you think it will surpass human intelligence? And what consequences will this have?

We need to focus primarily on how artificial intelligence will transform the workforce and job market. For instance, AI will be a key component of humanoid robots’ brains. Tesla is already producing them, and I believe that within the next 5 years, every automotive company is likely to produce their own version. This makes sense because automotive companies already have the assembly lines and engineering expertise to produce all the small components needed to build them. We’re already amazed by what AI can do today—imagine what it will do in 5 or 10 years, and then think about what it could do when integrated into a humanoid robot. It’s already confirmed through commercial orders with current manufacturers that major fast-food franchise chains and other chains, for example, in the transportation sector, will test humanoid robots within their processes. AI is already skilled in programming tasks and will soon be able to enhance itself.

The process of separating useful molecules from mixtures of other substances accounts for 15% of the nation’s energy, emits 100 million tons of carbon dioxide and costs $4 billion annually.

Commercial manufacturers produce columns of porous materials to separate potential new drugs developed by the pharmaceutical industry, for example, and also for energy and chemical production, environmental science and making foods and beverages.

But in a new study, researchers at Case Western Reserve University have found these manufactured separation materials don’t function as intended because the pores are so packed with polymer they become blocked. That means the separations are inefficient and unnecessarily expensive.
