Scientists map huge variety of animal life cycles

Their findings, published in Nature Ecology and Evolution, come from a detailed assessment of 121 species ranging from humans to sponges, may have important implications for conservation strategies and for predicting which species will be the winners and losers from the global environment crisis. “Pace of life” relates to how […]

New method helping to find deletions and duplications in the human genome

A new machine-learning method accurately identifies regions of the human genome that have been duplicated or deleted — known as copy number variants — that are often associated with autism and other neurodevelopmental disorders. The new method, developed by researchers at Penn State, integrates data from several algorithms that attempt […]

Light therapy could replace opioids as main treatment for cancer treatment side effect

A worldwide coalition of researchers and clinicians has agreed that light therapy is among the most effective interventions for the prevention of oral mucositis, painful ulcers in the mouth resulting from cancer therapy. The new guidelines from the Multinational Association of Supportive Care in Cancer (MASCC) and International Society of […]

Genetic Origin of Severe Developmental Eye Condition Identified

The finding is a promising step forward in understanding eye growth – and potentially fixing near- and far-sightedness. Those with a rare genetic condition called nanophthalmos have abnormally small eyes whose internal structures – including the size of the lens – are otherwise normal. The condition can cause a host […]

Hinge-like protein may open new doors in cystic fibrosis treatment

In recent decades, treatment options for people with cystic fibrosis have improved dramatically. The newest drugs, known as potentiators, target a protein called cystic fibrosis transmembrane conductance regulator, which is mutated in people with the disease. Yet, while these medications can help some people with cystic fibrosis, they are far […]

Molecules that Restructure the Mind

Imagine a molecule powerful enough to reconfigure your mind and body — a molecule that makes your bones and muscles grow, makes your organs behave differently and alters your mind and your mood. Such is the power of sex hormones — estrogen, progesterone and testosterone. These naturally occurring chemicals are […]

It's not an antibody, it's a frankenbody: A new tool for live-cell imaging

Scientists at Colorado State University (CSU) and Tokyo Institute of Technology (Tokyo Tech) have developed a new powerful tool called a “frankenbody”, for imaging protein dynamics in living cells. Just as Frankenstein's monster is stitched together from different limbs, the frankenbody was created by taking the binding regions of a […]

Anti-worm drug inhibits tumour growth and spread in mice

Researchers at UNSW Sydney have discovered that a drug used for almost 40 years to treat worm infections in humans and animals can be used to inhibit melanoma growth and spread in mice. The drug, which is available over-the-counter in Europe, is a so-called anthelmintic used to control parasitic infections. […]

Researchers probe cell division defects to gain insight into cancer

From bugs to plants to animals, for all living things to grow they must create more cells. To do so, each existing cell, whether in an embryo or an adult, receives cues to copy its chromosomes — large pieces of DNA that contain each cell’s entire genetic code. In a […]

Major breakthrough in the treatment of leukemia

A molecular process involved in the action of anti-leukemia drugs has been discovered at Université de Montréal’s Institute for Research in Immunology and Cancer (IRIC). While calling into question a central tenet of oncology, this discovery, published in the journal Cancer Cell, also holds promise for the development of effective treatments in the […]

Researchers can finally modify plant mitochondrial DNA

Researchers in Japan have edited plant mitochondrial DNA for the first time, which could lead to a more secure food supply. Nuclear DNA was first edited in the early 1970s, chloroplast DNA was first edited in 1988, and animal mitochondrial DNA was edited in 2008. However, no tool previously successfully […]

Virtual Reality?

Researchers in many fields of science and medicine engineer different types of human cells for drug testing and other purposes. They often begin with stem cells—unspecialized cells that have the potential to form many different types of tissue. By turning on certain genes, scientists attempt to coax stem cells into becoming […]

Study: Many Thyroid Cancer Patients Say They Had No Choice About Radioactive Iodine

After thyroid cancer surgery, many patients should be in the position of deciding with their doctors whether to pursue treatment with radioactive iodine to help ease long-term follow-up and offer reassurance that the cancer is gone. A new survey by researchers at the University of Michigan Rogel Cancer Center and U-M Institute […]

Freeze frame: researches solve how cells unfold proteins

A happy cell is a balanced cell, but for every stupendously twisted protein it creates, it must tear the old ones asunder. That means untangling a convoluted pretzel-like mass for recycling. Cdc48 plays a critical role in unraveling the spent proteins. “Cdc48 is like a Swiss army knife of the […]

Tiny change has big effects, reverses prediabetes in mice

A small chemical change — shifting the position of two hydrogen atoms — makes the difference between mice that are healthy and mice with insulin resistance and fatty liver, major risk factors for diabetes and heart disease. Making the change prevented the onset of these symptoms in mice fed a […]

Immune-boosting compound makes immunotherapy effective against pancreatic cancer

Pancreatic cancer is especially challenging to treat – only eight percent of patients are still alive five years after diagnosis. Chemotherapy and radiation therapy are of limited benefit, and even immunotherapy – which revolutionized treatment for other kinds of cancer by activating the body’s immune system to attack cancer cells – […]

One Simple Change Cut Unnecessary Imaging for Cancer Patients in Half

Simply introducing a default physician order — a “nudge” — into electronic health records (EHRs) cut the use of unnecessary daily imaging in half during palliative radiation therapy sessions for patients with advanced cancer, according to a Penn Medicine study published in JAMA Oncology. While daily imaging is typically used […]

Scientists Discover Autoimmune Disease Associated with Testicular Cancer

Using advanced technology, scientists at Chan Zuckerberg (CZ) Biohub, Mayo Clinic and UC San Francisco, have discovered an autoimmune disease that appears to affect men with testicular cancer. Called “testicular cancer-associated paraneoplastic encephalitis,” the disease causes severe neurological symptoms in men. They progressively lose control of their limbs, eye movements, […]

Smaller operational margins just as safe in high-risk melanoma

The standard treatment for aggressive skin cancer is to surgically remove the tumour. Researchers at Karolinska Institutet in Sweden now show that a 2 cm operational margin is sufficient, as opposed to the close to 4 cm margin previously applied by surgeons. For the study, which is published in The […]
