The Development of the Human Face and Head There’s a reason we can recognize someone we know, even in a crowd—humans are naturally drawn to faces. Our brains are excellent at picking out subtle differences in facial features, like jaw shape, eyebrow curves, or the height of cheekbones. Faces hold a special significance, not only in art and poetry but also in technology through facial recognition. The traits we see in faces play a big role in identifying who we are. “A face contains a lot of

This increases food competition and places additional stress on a species already facing severe decline. The findings, published today (17 November) in the Journal of Applied Ecology, introduce a new

Highlighted Resource As people get older or experience specific health issues, their bones may lose density. This reduction in bone mass can result in a condition called osteoporosis, where bones become fragile and more likely to break. Discover the types of medical exams used to assess bone mineral density. Understand how these test results help evaluate bone health and the potential risk for bone fractures. For more details, explore trusted medical resources about bone density testing and

Health Capsule Kidney stones are a fairly common health issue, affecting roughly 11% of men and about 6% of women at some point in their lives. A sudden, intense pain in the lower back, abdomen, or groin can often be the first sign. Other symptoms to look out for include blood in the urine, discomfort during urination, or a frequent urge to urinate. These stones develop when there is a high concentration of specific minerals in the urine. Over time, these minerals can crystallize to form

Complementary Approaches and COVID-19 What’s the Takeaway? What’s Known About Complementary Methods for Short-Term COVID-19 Symptoms? Some alternative therapies, including practices like traditional Chinese medicine and nasal rinsing, may help with COVID-19 symptoms, though the research supporting these benefits is limited. Many of the studies are either small, not rigorously conducted, or lack randomization, which makes their conclusions uncertain. A 2023 analysis of 33 studies (covering over

Health Update Breakthroughs in modern medicine are enabling people worldwide to live longer lives. However, with longer lifespans comes a gradual decline in physical capabilities. As people age, they often notice reductions in strength, balance, and mobility, but how these changes progress hasn’t been fully understood. To investigate this, researchers backed by the NIH evaluated the physical performance of 40 healthy adults. Half were between 50 and 64 years old, while the other half were 65 or

You’ve probably come across the terms "complementary," "alternative," and "integrative," but what exactly do they mean? This overview breaks down these concepts to help you better grasp their meanings and explains the purpose and contributions of the National Center for Complementary and Integrative Health (NCCIH). While the field and its language are continuously progressing, here are the definitions commonly used by the National Institutes of Health today.

What Is Colloidal Silver? Colloidal silver refers to a liquid that contains small silver particles suspended in it. While it is often marketed online as a supplement, there is no substantial scientific support for the health claims made about its use. Is Colloidal Silver Safe? The U.S. Food and Drug Administration (FDA) maintains that colloidal silver is neither safe nor proven effective in treating any medical condition. In fact, both the FDA and the Federal Trade Commission have taken

A fresh report unveiled today at the G20 Health Ministers Meeting in Limpopo, South Africa, underscores the urgent need for strategic funding and access plans to deliver new tuberculosis (TB) vaccines to adolescents and adults in countries most affected by the disease. The publication, titled “Catalyzing Solutions for Equitable Global Access and Sustainable Financing for New Tuberculosis Vaccines for Adults and Adolescents,” offers an unprecedented assessment of the challenges, limitations, and

The World Health Organization (WHO) and Bayer AG, a pharmaceutical company based in Germany, have extended their partnership to aid countries affected by neglected tropical diseases (NTDs) through the provision of free treatments. Since 2002, Bayer AG has contributed medicines to WHO’s NTD efforts, now overseen by the Department of Malaria and Neglected Tropical Diseases (MNT). The agreement, renewed for another five years from 2025 to 2030, will continue supplying certified medicines and

New research featured in The Lancet Global Health confirms that the substantial drop in maternal deaths worldwide over the last 20 years is largely due to advancements in both reproductive health services and maternal care. The study, titled “Effect of maternity care improvement, fertility decline, and contraceptive use on global maternal mortality reduction between 2000–2023: results from a decomposition analysis,” was conducted by the World Health Organization (WHO) along with the Human

Coenzyme Q10, also known as CoQ10, is a compound that occurs naturally within the human body. It is most abundant in organs with high energy needs, such as the heart, liver, kidneys, and pancreas. In the United States, CoQ10 is available as a dietary supplement. Due to its essential role in bodily functions and the fact that individuals with certain medical conditions often show lower levels of CoQ10, scientists have explored whether supplementing it could provide health benefits. Bottom Line •

Common Names: cinnamon, cinnamon bark, Ceylon cinnamon, cassia cinnamon Scientific Names: Cinnamomum verum (also called Cinnamomum zeylanicum and Laurus cinnamomum), Cinnamomum aromaticum (also known as Cinnamomum cassia) Background • Cinnamon is a popular spice obtained from the dried bark of certain Cinnamomum trees. The species Cinnamomum verum, often referred to as “true” cinnamon or Ceylon cinnamon, primarily grows in Sri Lanka. Cassia cinnamon (Cinnamomum aromaticum) is more commonly

The Benefits and Drawbacks of Health Screenings Many illnesses can begin without any noticeable symptoms. Conditions such as high blood pressure, high cholesterol, and some forms of cancer may develop quietly in their early stages. Health screenings are tests designed to detect early warning signs of diseases in individuals who appear to be well. Detecting issues early can be essential for beginning timely treatment and making lifestyle adjustments that could improve outcomes. Some screening

Photo Credit: Magnus Gålfalk A recent study from Linköping University reveals that greenhouse gas emissions from many wastewater treatment facilities may be more than double previous estimates. Using drones equipped with advanced sensors, researchers were able to directly measure methane and nitrous oxide emissions at multiple sites. "Our findings indicate that emissions from wastewater treatment processes have been

Image: Proteins are created through two main steps involving DNA. First is transcription, where DNA is copied into mRNA. Then comes translation, during which ribosomes read the mRNA and join amino acids in the right order to form a protein. The illustration depicts a streamlined version of the translation process, enabling faster and more efficient protein production.
