Like babies, eggs send signals when “hungry”

In humans and other mammals, the female reproductive cells – the eggs or oocytes – need nourishment in order to grow and remain fertile. It is known that the egg gets its food from little arm-like feeding tubes (called filopodia) that jut out from tiny cells surrounding the egg and […]

Mathematicians devise new model to study endovascular aneurysm sealing

Researchers at the University of Liverpool have developed a mathematical model that has the potential to improve the performance of endovascular aneurysm sealing (EVAS), which is an innovative procedure to treat abdominal aortic aneurysms (AAA). AAA is a swelling of part of the aorta inside the abdomen caused by a […]

Halting Intracranial Tumor Growth

  Harvard Medical School researchers at Massachusetts Eye and Ear have shown that mifepristone, a drug currently FDA-approved for chemical abortion, prevents the growth of vestibular schwannoma (also known as acoustic neuroma) cells. This sometimes-lethal intracranial tumor typically causes hearing loss and tinnitus. The findings, published online in Scientific Reports, suggest that […]

Some Can Combat Dementia by Using Still-Healthy Parts of Brain

People with the rare disease called primary progressive aphasia may recruit intact brain areas for help with language, according to a new UA-led study. People with a rare dementia that initially attacks the language center of the brain recruit other areas of the brain to decipher sentences, according to new […]

Early stimulation improves performance of bioengineered human heart cells

Researchers are now able to use induced pluripotent stem cells (iPSC) to form a model of human adult-like cardiac muscle by introducing electric and mechanical stimulation at an early stage. Since this muscle is similar to the adult heart, it could serve as a better model for testing the effects […]

Human anti-cancer drugs could help treat transmissible cancers in Tasmanian devils

Transmissible cancers are incredibly rare in nature, yet have arisen in Tasmanian devils on at least two separate occasions. New research from the University of Cambridge identifies key anti-cancer drugs which could be trialled as a treatment for these diseases, which are threatening Tasmanian devils with extinction. The research also […]

New camera gives surgeons a butterfly’s-eye view of cancer

Cancer lurking in tissue could be more easily found when looking through a butterfly’s eye. Researchers at the University of Illinois at Urbana-Champaign and Washington University in St. Louis have developed a surgical camera inspired by the eye of the morpho butterfly. The camera, connected to the goggles a surgeon […]

Negative Fateful Life Events and the Brains of Middle-Aged Men

Conflict, a death in the family, financial hardship and serious medical crises are all associated with accelerated physical aging. In a new study, researchers at the University of California San Diego School of Medicine found that such negative fateful life events — or FLEs — appear to also specifically accelerate […]

Study on nicotinic receptors and long-term memory could lead to more targeted and effective therapies for dementia

Currently, the main treatments for Alzheimer’s disease are drugs that increase levels of acetylcholine in the brain. The University of Bristol paper, published in Cell Reports, describes the role two main types of nicotinic receptor (α7 and α4β2 receptors) play in long-term memory retrieval and encoding – and the impact of […]

Technology holds personalised cancer vaccine breakthrough

University of Queensland researchers have developed a vaccine delivery technology that enables treatment to be tailored precisely for different cancers. UQ’s Professor Ranjeny Thomas said the technology had the potential to improve the precision of cancer immunotherapy, leading to better cancer outcomes and reduce harmful side-effects. “Flexible cancer vaccines are […]

Kidney age, not kidney disease

From the Universities of Oxford, Bristol and Johannesburg, the researchers argue that for some people a reduced level of kidney function is not necessarily a disease, but a normal and asymptomatic sign of ageing, given the clear link between decreasing kidney health and increasing age. Since 2002, the different stages of CKD […]

Accurately identifying aggressive head and neck cancers

Case Western Reserve University’s Center for Computational Imaging and Personalized Diagnostics (CCIPD) is leading a partnership working toward the first clinical trials to determine the aggressiveness of—and appropriate treatment for—certain head and neck cancers. Head and neck cancers (squamous cell carcinomas or HNSCC) represent more than a half-million cases and 300,000 deaths […]

Scientists developed a way to screen infants for type 1 diabetes

People are born with some conditions even though diagnosis doesn‘t come immediately. Scientists from the University of Queensland have developed a method to identify infants who will grow to develop type 1 diabetes. This will lead to better ways to conduct screenings in order to identify children at the highest […]

Drug compound shows promise against rheumatoid arthritis

Scientists have designed a new drug compound that dials down inflammation, suggesting possible future uses against autoimmune disorders such as rheumatoid arthritis. The new inhibitor is more selective than other compounds designed to target the same inflammatory pathway, according to new research from Washington University School of Medicine in St. […]

Antibody removes Alzheimer’s plaques, in mice

Years before people start showing characteristic symptoms of Alzheimer’s disease, sticky plaques begin forming in their brains, damaging nearby cells. For decades, doctors have sought ways to clear out these plaques as a way to prevent or treat the disease. The sticky clumps, known as amyloid plaques, are composed primarily […]

Three genes essential for cells to tell time

One family of genes allows cells to adapt to daily changes in environmental conditions by adjusting their internal “body clock,” the circadian clock responsible for regular sleep-wake cycles. The new discovery by University of Tokyo scientists reveals for the first time that circadian regulation may be directly connected to cellular […]
