Human evolution is closely related to the development of a larger brain. A new study suggests that high prenatal exposure to estrogen may have contributed to its expansion, and that traces of this hormone’s influence may be seen in the relative lengths of people’s fingers. Professor John Manning, a member of Swansea University’s Applied Sport, Technology, Exercise and Medicine (A-STEM) research team, specializes in the study of digit ratios. Finger proportions compare the length of the index finger, known as 2D, to the length of the ring finger, known as 4D. This measurement is called the 2D:4D ratio. Researchers use…

Recent research provides evidence that when faced with news of a conviction, voters spend more mental energy defending politicians from their own party and finding fault with their opponents. This finding suggests that party loyalty directly influences whether people view legal processes as legitimate or as politically motivated weapons. This research American behavioral scientist. The 2024 US presidential election presents an unusual situation in US political history. Both major political factions were facing significant legal disputes involving prominent figures. Former President Donald Trump was convicted of falsifying business records in connection with hush-money payments. Around the same time, Hunter Biden,…

Nanoplastics are already a concern because they can be directly ingested by people, but new research points to another possible danger. These small plastic particles can also make it more difficult to control harmful bacteria. In a study published in water researchVirginia Tech researcher Jingqiu Liao and an international team found that nanoplastics can interact with environmental microorganisms and pose indirect risks to human health, particularly through drinking water systems. “It is very important to better understand the negative effects of nanoplastics on human health and the negative effects not only on humans but also on the environment, which indirectly…

In young men with autism spectrum disorders, the physical arrangement of brain folds in areas associated with social and emotional processing appears to be altered. Recent analyzes of brain imaging data show that neurotypical boys often exhibit skewed folding patterns that are less common in boys with autism. The researchers published their research in a journal cerebral cortex. The human brain is characterized by a wrinkled outer layer known as the cerebral cortex. This structure is filled with raised ridges and deep grooves. Together, these folds work to maximize the amount of neural tissue that can fit within the narrow…

New research published in journal Psychology of religion and spirituality Our findings suggest that belief in hell may be associated with more conservative sexual behavior in different societies. The findings show that while religious beliefs help shape romantic choices, fear of supernatural punishment tends to act as a stronger social deterrent against casual sex and infidelity than the expectation of divine reward. Across many different cultures and historical periods, human societies have accepted the concept of an afterlife, where actions on earth are subject to divine judgment. Study authors Samudera Fadlilah Jamaluddin and Fakira Inayatulobani from the Department of Psychology…

Hello from Brooklyn, where the smoke from the wildfires is thick enough to bite. Everyone please stay safe. New idea to treat Duchenne muscular dystrophy divides experts Viral vectors, go for a hike. A small California startup jumped into the rare disease space last year, claiming it could treat Duchenne muscular dystrophy using a new method: ultrasound. Using ultrasound to guide genes to specific tissues is an old idea, and although researchers have considered using it to deliver chemotherapy to tumors,…

A large-scale genome analysis is changing scientists’ understanding of koala evolution. According to research, koalas (Phascolarctus Greius) A severe population decline occurred about 100,000 years ago, long before humans arrived in Australia. All koalas alive today are thought to have descended from a single ancestral population that endured dramatic environmental changes, including severe ice ages. However, modern koalas now face a different set of dangers. These include hunting, widespread land clearing, wildfires, and disease. The study, led by researchers from the University of Sydney and Texas A&M University, challenges previous research that found koala numbers declined only after humans arrived…

An analysis of study data from the Vanderbilt Memory and Aging Project found that a high-fat diet was associated with a rapid decrease in temporal lobe volume in participants without cognitive impairment. However, in people with mild cognitive impairment, adherence to the same type of diet was associated with delayed enlargement of the inferior ventricular region of the brain. The paper is Alzheimer’s disease and dementia. Although dementia is an inevitable part of normal aging, the risk of developing dementia increases as you get older. Dementia is a disorder characterized by a progressive decline in memory, reasoning, language, judgment, or…

Recent research published in current psychology This suggests that people are more likely to believe disinformation from someone who ignores the truth than from a liar who actively tries to deceive. This research shows that when a fact-insensitive person repeats a statement, it significantly increases how true that statement is perceived by the reader. These findings provide evidence that casual disregard for reality poses a uniquely powerful threat to public knowledge and beliefs. The digital age has made it increasingly difficult to track down misinformation. Information is often spread through acts known in psychology as “bullshit” as well as intentional…

Commonly used sweeteners can directly interfere with the growth of bacteria that support a healthy gut, according to laboratory research from the University of Cambridge. The strongest effects were seen when researchers combined isosteviol, a sweetener used in the food and beverage industry, with the antidepressant duloxetine. Combining the two compounds significantly reduced the growth of two important bacterial species associated with digestive health, blood sugar regulation, and immune function. Scientists caution that the experiment was carried out in a laboratory and not on humans. Therefore, further research will be needed to determine whether bacterial changes result in meaningful health…
