Researchers at the University of Bristol have discovered how microbes responsible for human African sleeping sickness produce sex cells. In these single-celled parasites, known as trypanosomes, each reproductive cell splits off in turn from the parental germline cell, which is responsible for passing on genes. Conventional germline cells divide twice […]

Dental and orthopedic implants are widely used around the world. Common causes for implant failure are the immune response against oral bacteria and titanium particles shed by the implant. These and other phenomena can generate an inflammatory response, activating the osteoclasts (bone resorbing cells), and ultimately leading to osteolysis (destruction […]

University of Alberta scientists have identified a receptor in cells that could be key to preventing permanent hearing loss in childhood cancer survivors who are being treated with the drug cisplatin. The researchers believe by inhibiting the receptor, they may be able to eliminate toxic side-effects from the drug that […]

A new study with zebrafish shows that a deadly form of skin cancer — melanoma — alters the metabolism of healthy tissues elsewhere in the body. The research from Washington University in St. Louis suggests that these other tissues could potentially be targeted to help treat cancer. “Tumors rely on […]

The quest to create safer, more successful pregnancies is one of the top goals of modern science. While pregnancy is better understood today than ever before, with improvements in technology helping to lower the risk of negative outcomes, there is much researchers still don’t know about a vital part of […]

Over the last two years, Multiply Labs has helped pharmaceutical companies produce biologic drugs with its robotic manufacturing platform. The robots can work around the clock, precisely formulating small batches of drugs to help companies run clinical trials more quickly. Now Multiply Labs, which was founded by Fred Parietti PhD […]

Since it debuted in 2011, the Get SET Early program, which provides pediatricians and parents with a relatively simple process to screen for indicators of autism spectrum disorder (ASD) in children as young as age 1, has steadily grown in use and validation. Early screening and identification of ASD has […]

Researchers at the University of California San Diego have laid the groundwork for a potential new type of gene therapy using novel CRISPR-based techniques. Working in fruit flies and human cells, research led by UC San Diego Postdoctoral Scholar Zhiqian Li in Division of Biological Sciences Professor Ethan Bier’s laboratory […]

New research at Karolinska Institutet suggests a link between psychosis and a genetic change that affects the brain's immune system. The study published in Molecular Psychiatry may impact the development of modern medicines for bipolar disorder or schizophrenia. Psychosis affects approximately 2-3 per cent of the population and is characterized […]

Targeting a heat production ‘brake’ on fat tissues may be a safer way to treat obesity than current medication. A receptor that helps conserve energy when food is scarce may be the key to a safer approach to treating diet-induced obesity, research led by the Garvan Institute of Medical Research […]

Neglect, calamitous events or even abuse: traumatic childhood experiences increase the risk of mental and physical illness and can lead to psychiatric disorders later in life. But how do stressful events early in life persistently affect brain functions? What happens in a child’s nerve cells when fear and stress overwhelm […]

Sleep is very important for us and you know it. If you don’t get a good night’s sleep, you definitely feel it. Duration of sleep is important, but other factors play a huge role as well. For example, interruptions. A new study from the University of Adelaide has revealed that […]

Is there any hope for people who are suffering from incurable diseases? Modern medicine shed light in the darkness in the form of a novel therapy, gene therapy. Gene therapy is a relatively new experimental technique, which uses the gene to treat, prevent or limit illness development. It is based […]

Simultaneous measurement of neural rhythms and spikes across five brain areas reveals how propofol induces unconsciousness. In a uniquely deep and detailed look at how the commonly used anesthetic propofol causes unconsciousness, a collaboration of labs at the Picower Institute for Learning and Memory at MIT shows that as the […]

Ask Paul Guenard how he’s doing and he’ll tell you, “Not bad for a guy who’s supposed to be dead!” While he laughs as he says it, Guenard did indeed face death six years ago when he underwent a stem cell transplant to treat mantle cell lymphoma. Afterwards, he said, […]

Investigational gene therapy can safely restore the immune systems of infants and children who have a rare, life-threatening inherited immunodeficiency disorder, according to research supported in part by the National Institutes of Health. The researchers found that 48 of 50 children who received the gene therapy retained their replenished immune […]

Americans are in chronic pain, and a comprehensive new study exploring trends in this major public health concern reveals that what has been a long-standing and under-acknowledged problem is getting substantially worse. The findings, published in the latest issue of the journal Demography, suggest blanket increases across multiple measures, with pain rising […]

Scientists at UC San Francisco are learning how immune cells naturally clear the body of defunct – or senescent – cells that contribute to aging and many chronic diseases. Understanding this process may open new ways of treating age-related chronic diseases with immunotherapy. In a healthy state, these immune cells […]

In 2015, researchers at UC San Francisco found a structure inside of tumor cells that biologists had never seen before. Even more surprising, a closer examination of the structure revealed that it contained signaling proteins known as receptor tyrosine kinases, or RTKs, which were thought to reside exclusively on the cell’s […]

Using a technique that could point to a new way to help people with severe anxiety and other treatment-resistant psychiatric illnesses, researchers at the University of Wisconsin–Madison successfully dialed down anxious monkeys’ overactive response to a potential threat by installing a custom chemical switch in their brain cells. About 30 […]

Researchers looking to help people suffering from addiction, depression, and pain are studying how certain brain neurons operate to see if they can be controlled. In a paper published in Neuron, researchers at the University of Washington School of Medicine and Washington University in St. Louis, along with several other […]

Imagine if you could get vaccinated for cancer. You would just get a shot or a couple of shots and your immune system would learn how to recognize and kill cancer. This sci-fi-sounding idea is not that far from reality. Especially now that scientists at the University of Waterloo have […]

DNA is basically a software code for the living organisms. It is constantly read and various processes are performed according to that encoded information. It is a good system and we’ve known about it for quite some time, but there is still a lot about it that we don’t know.  […]

Scientists at Case Western Reserve University School of Medicine have determined the structure of protein “fibrils” linked to Lou Gehrig’s disease and other neurodegenerative disorders—findings that provide clues to how toxic proteins clump and spread between nerve cells in the brain. Their results may also lead to developing drugs to […]

KRAS is one of the most common drivers of cancer and is involved in one-third of non-small cell lung cancers. It’s proved an elusive target thanks to its smooth structure and biochemistry. And although new inhibitors are demonstrating some success against one type of KRAS, new paths are needed. A […]

Rice University neurobiologist Rosa Uribe will be hitting the books for her latest study of the digestive system, but some of the pages in her books are a billion years old. Uribe, an assistant professor of biosciences, has won a five-year, $2 million R01 grant from the National Institutes of Health to […]

Say you get a CT scan to confirm whether your chest pain is from a fractured rib. You learn a few days later that no bone break was detected – yay! – but joy gives way to anxiety as you read the radiologist’s note, from the same scan, of a […]

A team of Oregon State University scientists has discovered a new class of anti-cancer compounds that effectively kill liver and breast cancer cells. The findings, recently published in the journal Apoptosis, describe the discovery and characterization of compounds, designated as Select Modulators of AhR-regulated Transcription (SMAhRTs). Edmond Francis O’Donnell III […]

COVID-19 can cause significant health problems. At one point it was reported that it can even cause lasting heart damage. And it is true. However, now scientists from UCL found that mild Covid-19 infection is very unlikely to cause lasting damage to the heart. This is good to hear because […]

A comprehensive review into what we know about COVID-19 and the way it functions suggests the virus has a unique infectious profile, which explains why it can be so hard to treat and why some people experience so-called “long-COVID”, struggling with significant health issues months after infection. There is growing […]
