Despite health warnings, Americans still sit too much

Most Americans continue to sit for prolonged periods despite public health messages that such inactivity increases the risk of obesity, diabetes, heart disease and certain cancers, according to a major new study led by researchers at Washington University School of Medicine in St. Louis. The research team analyzed surveys of […]

Stanford researchers work to genetically modify flatworms and unlock their regenerative powers

Slice it into a hundred pieces if you want, and the millimeters-long flatworm called a planarian won’t particularly care. Each piece can grow back into a new worm. But how they do that, and what scientists could learn about how to regenerate our own bodies, has remained mysterious because one of the […]

Rare disease gives new insight into regulatory T cell function

An international study led from Karolinska Institutet provides new insights into the regulatory T cells’ role in protecting against autoimmune disease. By mapping the targets of the immune system in patients with the rare disease IPEX, they were able to show that regulatory T cells control immunotolerance in the gut. […]

Pregnant women with type 1 diabetes are at risk of giving birth prematurely

Pregnant women with type 1 diabetes are at increased risk of delivering their baby prematurely. The risk increases as blood sugar levels rise, however women who maintain the recommended levels also risk giving birth prematurely. These are the findings from researchers at Karolinska Institutet and the Sahlgrenska Academy in Sweden, […]

To protect stem cells, plants have diverse genetic backup plans

Despite evolution driving a wide variety of differences, many plants function the same way. Now a new study has revealed the different genetic strategies various flowering plant species use to achieve the same status quo. In flowering plants, stem cells are critical for survival. Influenced by environmental factors, stem cells […]

A light-activated remote control for cells

What if doctors had a remote control that they could use to steer a patient’s own cells to a wound to speed up the healing process? Although such a device is still far from reality, researchers reporting in the ACS journal Nano Letters have taken an important first step: They used near-infrared […]

Discovery of genetic variants that protect against obesity and type 2 diabetes could lead to new weight loss medicines

Around four million people in the UK carry genetic variants that protect them from obesity, type 2 diabetes and heart disease, suggests new research from the University of Cambridge. The team say the discovery could lead to the development of new drugs that help people lose weight. Scientists have known […]

Study: Drugs reprogram genes in breast tumors to prevent endocrine resistance

Treating breast tumors with two cancer drugs simultaneously may prevent endocrine resistance by attacking the disease along two separate gene pathways, scientists at the University of Illinois found in a new study. The two drugs used in the study, selinexor and 4-OHT, caused the cancer cells to die and tumors […]

Common anti-inflammatory could protect baby brains

Administering ibuprofen immediately after birth may reduce brain damage in tiny growth-restricted babies, University of Queensland researchers have found. The UQ Centre for Clinical Research’s Dr Julie Wixey said the drug could help reduce the incidence of serious long-term neurological problems in these babies. “It’s often difficult to diagnose babies at risk of being […]

‘Super-Hero’ Stem Cells Survive Radiation to Regrow Muscles

Muscle damage is a common side effect of radiation therapy for cancer treatment, and is made worse because the very stem cells responsible for repairing injured muscles typically bear the brunt of radiation damage. Now UC San Francisco researchers have discovered a new type of stem cell in mouse muscles […]

Stanford doctors, materials scientists hope a blood test will encourage more colon cancer screenings

Colorectal cancer is the second leading cause of cancer deaths in the U.S. and a growing problem around the world, but not because it’s a particularly difficult cancer to detect and halt. The problem, doctors and researchers believe, is that not enough people are being screened for early signs of […]

‘Longevity gene’ responsible for more efficient DNA repair

Explorers have dreamt for centuries of a Fountain of Youth, with healing waters that rejuvenate the old and extend life indefinitely. Researchers at the University of Rochester, however, have uncovered more evidence that the key to longevity resides instead in a gene. In a new paper published in the journal Cell, the […]

Simple and Fast Method for Radiolabelling Antibodies against Breast Cancer

Radioactive antibodies that target cancer cells are used for medical diagnostics with PET imaging or for targeted radioimmunotherapy. Researchers from the University of Zurich have created a new method for radiolabelling antibodies using UV light. In less than 15 minutes, the proteins are ready-to-use for cancer imaging or therapy. Radioactive […]

Healthy meal kits can boost children’s long-term health

A scheme that helped parents plan well-balanced family dinners for three months kept their children healthier for years after, a study has found. Low-income families who were given simple recipe kits to cook five healthy meals a week decreased their children’s body mass index (BMI) compared with peers who continued […]

Appetite-regulating hormone levels in breast milk vary by mother’s weight

Nearly 20 percent of children and adolescents and 14 percent of toddlers in the United States are obese. One contributing factor, among many possibilities, may be what a baby eats during their critical first six months of life and how it affects their continued growth. Ideally, breast milk is their […]

Treating Excess of One Hormone Shows Promise for Decreasing the Risk of Obstructive Sleep Apnea

Treating the overproduction of one hormone may be a way to help a subset of the millions of Americans who suffer from obstructive sleep apnea, according to a new study. People with obstructive sleep apnea stop breathing for short periods while they are sleeping, which leads to a poor night’s […]

New research could prevent jaw damage in patients being treated for cancer or osteoporosis

SC researchers and collaborators report a breakthrough to prevent damage to the jaw, a side effect suffered by some people undergoing treatment for cancer or osteoporosis. The newly published research is an important step toward a cure for osteonecrosis of the jaw, a rare side effect caused by drugs commonly used to […]

Gene therapy restores immunity in infants with rare immunodeficiency disease

A small clinical trial has shown that gene therapy can safely correct the immune systems of infants newly diagnosed with a rare, life-threatening inherited disorder in which infection-fighting immune cells do not develop or function normally. Eight infants with the disorder, called X-linked severe combined immunodeficiency (X-SCID), received an experimental […]

Fuel for Drug Resistance

About one in eight women in the U.S. will develop breast cancer in her lifetime. The vast majority of these cancers rely on the hormone estrogen to grow. Estrogen-receptor positive (ER+) breast cancer tumors are frequently treated with the drug tamoxifen, which blocks the hormone’s effect on the tumor. However, […]

Preventing triple negative breast cancer from spreading

A breast cancer cell is like a house with three locks on the front door. Keys, or receptors, allow drugs to unlock the door and kill the cell. However, in triple-negative breast cancer, these keys are absent, thereby resulting in few options for drug therapy, until now. A protein called […]

Behavioral disorders in kids with autism linked to reduced brain connectivity

More than a quarter of children with autism spectrum disorder are also diagnosed with disruptive behavior disorders. For the first time, Yale researchers have identified a possible biological cause: a key mechanism that regulates emotion functions differently in the brains of the children who exhibit disruptive behavior. The study appears […]
