Healing hydrogels

Hydrogels are polymer materials made mostly from water. They can be used in a wide range of medical and other applications. However, previous incarnations of the materials suffered from repeated mechanical stress and would easily become deformed. A novel crystal that can reversibly form and deform, allows hydrogels to rapidly […]

Tiny implant cures diabetes in mice without triggering immune response

A team of researchers led by diabetes specialists and biomedical engineers at Washington University School of Medicine in St. Louis and Cornell University has demonstrated that using a miniscule device, they can implant insulin-secreting cells into diabetic mice. Once implanted, the cells secrete insulin in response to blood sugar, reversing […]

A connectomic study of a petascale fragment of human cerebral cortex

The human brain is the most interesting object in neuroscience. Recently, researchers from Harvard University and Google released a 1.4-petabyte dataset of a small sample of the human cerebral cortex (a surface layer of the brain, responsible for higher-level cognitive functions). The sample has been imaged at 4nm-resolution using electron […]

Case Western Reserve-led research team aims to determine which diabetic individuals can successfully donate corneas for transplant (and which should not)

About a third of the corneal transplant surgeries in the United States involve people with diabetes who donate their corneas after death. The number of corneal transplants has grown over the last decade, but through continuous research, the medical community has learned that not all corneal tissue from diabetics may […]

VUMC team discovers new genetic disease

Researchers at Vanderbilt University Medical Center have discovered a new genetic disease that causes a severe form of neurogenic orthostatic hypotension, a rapid drop in blood pressure upon standing that can cause fainting. The rare condition, which they named familial autonomic ganglionopathy, is caused by variations in the CHRNA3 gene, […]

Studying guppies, researchers find ADHD drugs can affect later generations

By studying guppies, scientists at the University of Toronto and Florida State University found that behaviours affected by methylphenidate hydrochloride (MPH) – the active ingredient in stimulants such as Ritalin and Concerta used to treat ADHD – can be passed along to several generations of descendants. “We exposed male and female Trinidadian […]

Hearing loss in older people can be preventable while young, argue experts

A new model by University of Manchester researchers has proposed a way to prevent hearing loss in older people by addressing socioeconomic inequalities encountered while young. Published in Trends in Hearing the team hope the model could impact the estimated 466 million people worldwide who have disabling hearing loss, mostly affecting […]

Women’s stronger immune response could protect from some skin cancers

Women may have a stronger immune response to a common form of skin cancer than men, according to early research on mice and human cells. Led by University of Manchester scientists at the Cancer Research UK Manchester Institute, the team publish their findings in Clinical Cancer Research. The study is funded by The Wellcome […]

Scientists Identify Genes Involved in Neuron Development

Neurons result from a highly complex and unique series of cell divisions. For example, in fruit flies, the process starts with stem cells that divide into mother cells (progenitor cells), which then divide into precursor cells that eventually become neurons. A team from the University of Michigan, spearheaded by graduate […]

Ultrasound Technology Developed at U-M now in Clinical Trials for Liver Cancer

The University of Michigan is one of eight sites around the country that will enroll patients in a clinical trial to evaluate the safety and efficacy of a technology that uses ultrasound to treat liver tumors. The #HOPE4LIVER trial will employ the noninvasive technique to mechanically destroy primary and metastatic liver tumors. […]

How HIV infection shrinks the brain’s white matter

It’s long been known that people living with HIV experience a loss of white matter in their brains. As opposed to grey matter, which is composed of the cell bodies of neurons, white matter is made up of a fatty substance called myelin that coats neurons, offering protection and helping […]

Why are you gaining weight after losing it?

A lot of people are trying to lose some weight. Some just want to look better for the summer, others are fighting for better health and well-being. Losing weight is not easy and many people find themselves gaining weight soon after losing it. What makes it difficult to maintain a […]

Recent Research Sheds Light on Link Between Meningiomas and Seizures

Meningiomas are the most common type of primary brain tumor. Found in the meninges– or the tissue that surrounds the brain and spinal cord, meningiomas are often benign. However, some can behave more aggressively and recur. These tumors can affect critical neurovascular structures, such as arteries and cranial nerves, impacting […]

Scientists found a way to reduce scarring

While some people find it unsightly, scarring is actually quite an interesting thing. Scar tissue is harder and more resilient and its formation is one of the body’s natural functions. However, scars can also be quite uncomfortable or even painful. Now scientists at the University of Queensland have found a […]

Advanced Photon Source helps reveal how antibodies bind a molecule linked to cancer

Researchers have developed antibodies that can bind to phosphohistidine, an unstable molecule that’s linked to cancer. To learn how the two bind together, the team turned to the powerful X-rays at Argonne’s Advanced Photon Source. Scientists are harnessing hard X-rays in the fight against cancer. A team of researchers, in […]

New light-activated drug acts like a Trojan horse to kill cancer cells

The goal of modern cancer treatments is to kill off cancer cells while causing the least amount of damage to the surrounding tissue. This is not easy to do with current therapies, which often cause significant side effects. Now researchers at the University of Edinburgh have tested new light-activated drugs […]

Head injury and concussion in toddlers: early detection of symptoms is vital

A research team led by scientists at Université de Montréal has developed a unique observational tool for assessing children up to 5 years of age who have had a concussion. The work is explained in a study published in the Journal of Head Trauma Rehabilitation. Pediatric traumatic brain injury (TBI) is particularly […]

Low on Antibodies, Blood Cancer Patients Can Fight off COVID-19 with T Cells

Antibodies aren’t the only immune cells needed to fight off COVID-19 — T cells are equally important and can step up to do the job when antibodies are depleted, suggests a new Penn Medicine study of blood cancer patients with COVID-19 published in Nature Medicine. The researchers found that blood cancer patients with COVID-19 […]

Cholesterol-carrying protein found to help suppress immune response in pancreatic tumor microenvironment

A protein involved in cholesterol metabolism plays a previously unknown role in suppressing the body’s natural immune defenders in and around pancreatic tumours, research led by the University of Michigan Rogel Cancer Center finds. ApoE, an apolipoprotein known to play roles in cardiovascular disease and Alzheimer’s, is elevated in the blood of people […]

Improved detection of atrial fibrillation through new devices could prevent a significant number of disabling strokes

A clinical trial examining the efficacy of two devices to monitor and detect atrial fibrillation (AF), or an irregular heartbeat, in ischemic stroke patients—one an implantable device that monitors over 12 months, the other an external device that monitors over a 30-day period—found the implantable device is more than three […]

The consequences of malnutrition are inheritable

Infant malnutrition damages the composition of intestinal bacteria, the microbiome. It has life-long consequences on the physical and intellectual development of affected children. Using pigs and mice models, Professor Bernard Henrissat from DTU Bioengineering in collaboration with the Washington University School of Medicine (USA), shows that damage to the microbiome […]

Memory, learning and decision-making studied in worms

As anyone who has ever procrastinated knows, remembering that you need to do something and acting on that knowledge are two different things. To understand how learning changes nerve cells and leads to different behaviors, researchers studied the much simpler nervous system of worms. “In this study, we can now […]
