Human biology
Human biology is an academic field of biology which focuses on humans; it is closely related to medicine, primate biology, and a number of other fields. A human being is a multicellular eukaryote consisting of an estimated 100 trillion cells. It should be noted that there is no consensus on the actual number of cells in the human body; estimates vary widely. As a species, humans are primates and can be distinguished from other primates by their more highly evolved brains. Even though humans are multicellular animals, many of the basic life processes of human cells are basically the same as in simple unicellular eukaryotes such as yeast and even prokaryotes.

Apr. 10, 2026 Alzheimer’s isn’t just one problem—it’s a tangled mix of biology, aging, and overall health. That’s why drugs targeting a single factor have fallen short, even as new treatments show modest benefits. Scientists are now pushing toward ...
Apr. 10, 2026 A common eye-health nutrient, zeaxanthin, may also help the body fight cancer more effectively. Scientists discovered it strengthens T cells and enhances the impact of immunotherapy treatments. Found in everyday vegetables and supplements, it’s ...
Apr. 9, 2026 Dragonflies may see the world in a way that pushes beyond human limits—and surprisingly, they do it using the same molecular trick we evolved ourselves. Scientists discovered that these insects can detect extremely deep red light, even edging into ...
Apr. 9, 2026 Cancer drugs known as BET inhibitors once looked like a breakthrough, but in real patients they’ve often fallen short. New research reveals a key reason why: two closely related proteins, BRD2 and BRD4, don’t actually do the same job. Instead, ...
Apr. 9, 2026 A breakthrough in microbiome research could change how colorectal cancer is detected—no colonoscopy required. Scientists used AI to map gut bacteria at an unprecedented level of detail, revealing subtle microbial patterns linked to cancer. By ...
Apr. 9, 2026 A hidden waste-removal pathway in the brain has finally been caught in action. Using cutting-edge MRI scans, researchers discovered that fluid flows along the middle meningeal artery in a slow, lymphatic-like pattern—very different from blood. ...
Apr. 9, 2026 Scientists are uncovering a surprising connection between autism and ADHD that goes deeper than labels. Instead of diagnoses, it’s the severity of autism-like traits that seems to shape how the brain is wired—even in children who don’t ...
Apr. 9, 2026 A new study reveals that gut bacteria may play a key role in triggering ALS and frontotemporal dementia. Harmful sugars produced by these microbes can spark immune responses that damage the brain. This breakthrough explains why some genetically ...
Apr. 9, 2026 Not all parts of our genetic code are equal, even when they appear to say the same thing. Scientists have discovered that cells can detect less efficient genetic instructions and selectively silence ...
Apr. 9, 2026 Weight loss drugs and bariatric surgery may work differently, but they lead to surprisingly similar results inside the body. Both significantly reduce fat while also causing a modest loss of muscle, reshaping overall body composition. Since muscle ...
Apr. 9, 2026 Chronic inflammation often works quietly in the background but can fuel serious diseases like diabetes, heart disease, and cancer. New research reveals that everyday plant compounds—like menthol from mint, cineole from eucalyptus, and capsaicin ...
Apr. 8, 2026 Scientists have developed a clever new way to trap “forever chemicals” in water using nano-sized cages that lock onto PFAS molecules. Unlike current methods, this approach can capture short-chain PFAS—the hardest type to remove. Tests show it ...
