New research suggests that human hair does not grow by being pushed out from the root, as was long believed. Instead, scientists discovered that hair is pulled upwards by forces created by a hidden network of migrating cells within the hair follicle. The discovery challenges decades of biology textbook explanations and could impact how researchers approach hair loss and hair regrowth. Researchers from L’Oréal Research & Innovation and Queen Mary University of London used advanced 3D live imaging to observe individual cells within living human hair follicles maintained in laboratory culture. Their findings are: nature communicationsfound that cells within the…

Pharmacologists, drug development executives, and regulatory affairs professionals confront accelerating pharma trends in 2026 that reshape drug discovery, biopharma manufacturing, clinical pipelines, and FDA approvals. Discover key insights to stay ahead.

Early signs of dementia are rarely dramatic. They don’t forget names or misplace keys, but they are changes so subtle that they are almost impossible to notice. This means a slightly narrower vocabulary, less variation in descriptions, and a mild flattening of the language. New research by my colleagues and I suggests that these changes may be detectable years before a formal diagnosis is made. And one of the clearest examples may be hidden in Sir Terry Pratchett’s novels. Pratchett is remembered as one of Britain’s most imaginative writers, the creator of the Discworld series, and a master of satire…

Some of the nation’s largest lobbying firms are working simultaneously on both sides of the Pfas “forever chemical” issue, raising serious questions about conflicts of interest and concerns that their activities are slowing states’ efforts to curb the public health threat.A review of lobbying records in six states conducted by the nonprofit F-Minus found a variety of scenarios in which companies lobbied on both sides. The most common PFAs are associated with cancer. Lobbying firm Holland & Knight is affiliated with the American Chemistry Council, which represents the largest Pfas manufacturers in the United States, and has actively opposed most…

Recent research published in Sexual behavior archives This suggests that young women who are open to “sweet relationships” tend to experience deeper psychological vulnerabilities, such as difficulties with emotional coping and relationship skills. This study provides evidence that accepting to exchange intimacy for material gain is often associated with negative childhood experiences that shape the way people view themselves and others. Sugar relationships involve arrangements in which companionship or sexual intimacy is exchanged for resources such as money or gifts. Public discussions about these arrangements tend to focus on the financial or ethical aspects of the exchanges. The authors of…

Most people are familiar with the concept of deep space, but scientists also study something called deep time. Advances in genetics have allowed researchers to trace biological changes farther back in time than ever before. Even with these powerful tools, many questions remain unanswered. A long-standing mystery has puzzled biologists for decades. Genes and their functions are often surprisingly similar between species, even if those species diverged hundreds of millions of years ago. This pattern appears in both plants and animals. But the same consistency doesn’t seem to apply to DNA, which controls when genes are turned on or turned…

Irritable bowel syndrome (IBS) is a widespread digestive disorder that affects the gastrointestinal tract. It occurs more often in women and causes symptoms such as abdominal pain, constipation, and diarrhea. The exact cause of IBS is still unknown. However, scientists believe that conditions within the gut, such as the gut microbiome and the chemical messenger serotonin, play an important role. Serotonin is widely recognized as a neurotransmitter in the brain that influences mood. But more than 90 percent of the body’s serotonin is actually produced in the gut. There, it regulates intestinal activity through the enteric nervous system, often referred…

Researchers at the University of Cambridge have developed a new technique that uses light instead of toxic chemicals to transform complex drug molecules. This discovery has the potential to accelerate drug development and make the drug design process more efficient. The study was published on March 12th. natural synthesisintroduces what the team calls an “anti-Friedelcrafts” reaction. Traditional Friedel-Crafts chemistry requires strong chemicals or metal catalysts and harsh laboratory conditions. Because of these requirements, reactions are typically carried out in the early stages of drug manufacturing, followed by many additional chemical steps to produce the final drug. The new Cambridge method…

Researchers have given a newly identified Australian tree species an unusual nickname. Scientists call it a “zombie” tree. This is because, although some individuals are still alive, this species is unable to grow and reproduce normally without extensive intervention. University of Queensland botanist Professor Rod Fensham said urgent action was needed to prevent this species. rodamnia zombie It is not wiped out by a fungal disease known as myrtle rust. “When it was first assessed in 2020, this species had no name. Since then, myrtle rust has killed 10 per cent of the trees, and none of the remaining trees…

Tiny pieces of plastic, known as microplastics, may contribute to neurodegenerative diseases such as Alzheimer’s and Parkinson’s disease. A new study outlines five biological mechanisms by which these particles can cause inflammation and damage in the brain. Dementia already affects more than 57 million people worldwide, and the number of people diagnosed with Alzheimer’s and Parkinson’s diseases is expected to increase significantly in the coming years. Scientists say microplastics can worsen or accelerate these diseases, raising serious public health concerns. Associate Professor Kamal Dua, a pharmaceutical scientist at the University of Technology Sydney, estimates that adults consume around 250 grams…
