Pushing through brain barriers

A Case Western Reserve University engineering professor is developing a miniaturized low-power device to detect how electrical signals and neurotransmitters in the brain work. The device will record 16 channels of chemical and electrical neural activity, measuring neurotransmitters and action potentials in real time.

Lifestyle changes remain important in fighting peripheral arterial disease

Researchers found that modifying risk factors through healthy lifestyle changes remains vital to combating peripheral arterial disease. While some patients with blocked leg arteries may not exhibit symptoms, early detection and treatment are still essential to prevent progression and potential complications.

Infant sucking habits may affect how baby talks

A recent study published in BMC Pediatrics found that persistent sucking habits in infants, such as pacifier or bottle use, may lead to difficulty producing certain word sounds and simplifying pronunciation in preschool children. Delaying introduction of baby bottles until at least 9 months old can reduce the risk of speech disorders.

The bowels of infection

Researchers found that latent CMV infection exacerbated intestinal inflammation and increased immune responses to normally harmless bacteria, contributing to IBD severity. Latent CMV infection may modulate mucosal immunity and predispose individuals to developing severe acute colitis and subsequently IBD.

Time-keeping brain neurons discovered

Researchers have identified groups of neurons that precisely keep time in the primate brain, allowing for fine-scale control over actions. The discovery opens doors to investigations into how the brain produces and uses its natural time code.

Alzheimer's lesions found in the retina

Researchers have discovered that Alzheimer's disease can cause changes in the retina, which may predict how well treatments will work. The findings could lead to the development of retinal imaging technology for earlier diagnosis and treatment of Alzheimer's, a leading cause of elderly dementia.

Cancer survivors may not be getting the help they need to stop smoking

A recent study published by Fox Chase Cancer Center researchers reveals that nearly a quarter of cancer survivors who still smoke have not been advised to quit by their health care providers in the last year. Health care providers are missing an opportunity to make a significant difference in the quality of life of their patients by no...

Melanoma treatment options 1 step closer

A team of University of Alberta researchers successfully synthesized a natural substance called Palmerolide A, which shows exceptional potential to specifically treat melanoma. The potency of palmerolide is exceptional and may prove to be more effective with less toxicity than current chemotherapy approaches.

Radiologists develop scale to help clinicians predict disease severity in infants with NEC

A new scale, the Duke Abdominal Assessment Scale (DAAS), helps clinicians determine disease severity and need for surgery in infants with NEC. The DAAS provides a standardized 10-point radiographic scale that increases with disease severity, enabling earlier detection of patients at risk for developing severe NEC.

It takes 2 to tutor a sparrow

In a field study, University of Washington researchers found that juvenile song sparrows learn their repertoire by eavesdropping on singing conversations between two adult birds. This process involves tracking the birds' movements and responses to recorded bird songs played over two speakers.

0.2 second test for explosive liquids

Researchers have developed a new spectroscopy method that can detect explosive liquids in plastic bottles instantly, improving airport security. The method uses electromagnetic radiation to identify materials and a nanoelectronic device to detect signals, creating a detailed 'thumbprint' of the liquid's molecular signature.
