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…

Tungsten cobalt carbide (WC-Co) is widely praised for its extremely high hardness, but its strength makes it extremely difficult to shape and manufacture. Current production methods consume large amounts of expensive materials while achieving relatively modest yields. As a result, researchers have sought more efficient and economical ways to produce these extremely durable materials. WC-Co cemented carbide is essential for applications where strong wear resistance and high hardness are required, such as cutting tools and construction tools. Traditionally, these materials are produced by powder metallurgy. In this process, WC and Co powders are compressed under high pressure and heated in…

A smartphone app designed to tackle the underlying psychological causes of premature ejaculation could significantly improve your sex life and delay ejaculation, while offering a way to reduce the stigma around premature ejaculation, researchers say. Data from the CLIMACS study will be presented today (Saturday 14 March 2026) at the European Association of Urology Annual Meeting (EAU26) in London. This is the first study to test a digital-first approach to treating premature ejaculation at home. This app provides men with evidence-based information about this condition, along with teaching them several treatment techniques, tips, and exercises designed by urologists and psychologists.…

A new study led by the University of Utah has discovered the mechanism behind a decades-old evolutionary mystery: how “selfish chromosomes” trick the rules of inheritance. Researchers discovered that rogue chromosomes were hijacking the system. Overdrive (Ovd) gene To destroy the rival’s sperm. This research Ofdo Genes act as quality control checkpoints during sperm development. usually, Ofdo Detect and remove abnormal sperm cells. But selfish chromosomes exploit this system to kill their competitors and increase their chances of being passed on to the next generation. The discovery revealed the biology behind segregation distortion, a phenomenon in which genes favorably vary…

Specialist resource centers within mainstream secondary schools (a type of ‘inclusion-based’ school) may lead to improved academic performance, better attendance and a greater sense of belonging for students with autism, according to new three-year research from the University of Surrey. However, research suggests that placement alone does not determine happiness. Rather, students’ perceptions of teacher and peer support were the strongest and most consistent predictors of positive adjustment. Researchers followed 119 autistic students aged 11 to 14 in seven mainstream secondary schools and compared three types of provision: placement in specialized resource centers (SRCs), mainstream placement in schools hosting SRCs,…

New LMU research shows how proteins can function reliably even without a stable 3D structure, showing that not only short sequence motifs but also chemical properties are critical. Many proteins are not only composed of stably folded building blocks. They also contain flexible parts known as intrinsically disordered regions (IDRs) that do not form stable three-dimensional structures but play important roles within cells. Such disordered protein domains constitute approximately one-third of all protein structures. Recently, they have attracted significant attention, especially as it has been revealed that they are involved in diverse interactions, can form biomolecular condensates, and are involved…
