New research into Neanderthal remains unearthed from a Belgian cave sheds light on a disturbing aspect of prehistoric life. Researchers analyzing human bones from the Troisièmes cave in Gohiers, Belgium, found evidence that Neanderthals practiced selective cannibalism between 41,000 and 45,000 years ago. Bodies indicate that adult women and children were the main victims. For the first time, scientists were able to construct biological profiles of the people whose bones were found at the site. Their findings suggest that these people did not belong to the local Neanderthal group that lived in the area. Rather, they may have come from…

A study of more than 1,000 boys and girls ages 9 to 13 found that those who played the Roblox adventure video game Super U Story had slightly better body satisfaction compared to those who played Rainbow Friends 2 Story immediately after the game. However, changes in body satisfaction did not differ from the group that performed the web-based word search. The paper was published in. Medical Internet Research Journal. Body satisfaction refers to the degree to which an individual feels positively about his or her appearance and physical characteristics. This includes perceptions, thoughts, and feelings related to your body…

More than one in four people with type 2 diabetes uses GLP-1 receptor agonists, a type of widely prescribed medication. But a new study by Stanford Medicine and international collaborators suggests that these drugs may be less effective in some people due to genetic differences. Approximately 10% of the population carries a specific genetic variation associated with a newly identified phenomenon called GLP-1 resistance. In these people, levels of the hormone GLP-1 (glucagon-like peptide-1), which helps regulate blood sugar, are actually higher than normal, but they appear to be less effective at work. It remains unclear whether these genetic variations…

A comprehensive review of neuroimaging studies suggests that problematic smartphone use is associated with distinct structural and functional changes in the brain. These changes primarily involve neural circuits responsible for reward processing, executive control, and emotional regulation. This analysis shows that the powerful motivators of smartphones may be due to how these devices tap into the brain’s social cognitive networks and reinforce habits through digital social feedback and avoidance of social exclusion. These findings were published in the journal Advances in neuropsychopharmacology and biological psychiatry. The use of smartphones is pervasive around the world and integrated into nearly every aspect…

Breast cancer is the most commonly diagnosed cancer in women worldwide. According to the World Health Organization, about 2.3 million women will be diagnosed with the disease in 2022, and about 670,000 will die from the disease. Although treatments have improved in recent years, some forms of breast cancer are particularly aggressive and difficult to manage. One of the biggest challenges doctors face is that there is no reliable way to predict how these rapidly growing cancers will progress. A new research initiative called Biomarker Research, which integrates data from glycoimmune signatures and clinical evidence in breast cancer, is working…

More than a quarter of people with type 2 diabetes take GLP-1 receptor agonists, but common diabetes drugs may be less effective for people with certain genetic mutations, according to a new study by Stanford Medicine scientists and their collaborators. This genetic mutation, carried by about 10% of the general population, causes a surprising and still mysterious phenomenon that researchers call GLP-1 resistance. This phenomenon results in high levels of the hormone GLP-1 (glucagon-like peptide-1), which helps regulate blood sugar, but with low biological efficacy. It’s unclear whether the variant will affect weight loss from drugs such as Ozempic and…

The virus is so effective at entering human cells, thanks in large part to the special proteins that coat its outer surface. These proteins are important targets for vaccine development. To study these, scientists usually create a laboratory version to see how the immune system responds. However, these simplified versions often omit important sections that are normally located within the outer membrane of the virus. As a result, antibodies don’t always behave the same way they would during an actual infection, making it difficult to understand how antibodies actually recognize and stop the virus. Scripps Research researchers, in collaboration with…

Every person has a unique pattern of breathing through their nose, which is stable over time and acts like a biological signature. By tracking how individuals inhale and exhale over a 24-hour period, new research has demonstrated that these unique breathing patterns can identify people with near-perfect accuracy, while also predicting an individual’s levels of anxiety, depression, and weight. The study was published in the journal Current Biology. Breathing frequently seems like an automatic and simple physical process. Many people only become aware of their breathing when they are out of breath or after intense exercise. However, the act of…

The first published study of Tinshemet Cave is changing the way scientists understand the relationship between Neanderthals and Homo sapiens. Evidence from this site indicates that these groups did not simply live together during the Middle Paleolithic period of the Middle Levant. They interacted directly, sharing tools, lifestyles, and even burial customs. These interactions seem to have fostered cultural growth, more complex social behavior, and innovations such as the symbolic use of ocher for formal burials and decoration. The findings point out that the Levant served as a major crossroads in human history, and that human interaction, rather than isolation,…
