No good substitute for race in college admissions: Research

A new study by the University of Maryland finds that socioeconomic diversity can enhance student interactions and learning from each other, but racial diversity remains essential. The research challenges the idea that socio-economic status can serve as a substitute for considering an applicant's race in college admissions.

Helping pet owners make tough choices

A new survey tool is being developed to help pet owners monitor their dogs' quality of life during chemotherapy for cancer. The tool, based on a pilot study with 29 dog owners and veterinarians, found that certain behavioral changes can indicate the animal's quality of life, providing a common ground for treatment decisions.

Major hurdle cleared to diabetes transplants

Researchers at Washington University School of Medicine have identified a way to trigger the reproduction of human insulin-producing beta cells in a laboratory setting, potentially removing a significant obstacle to transplanting these cells as a treatment for patients with type 1 diabetes. This new technique uses a cell conditioning s...

Helping to restore balance after inner ear disorder

A new study has designed and tested a vestibular prosthesis to help restore balance in individuals with Meniere's disease. The prosthesis uses electrical stimulation to activate the vestibular nerve, aiming to alleviate symptoms such as vertigo and tinnitus. However, further research is needed to fine-tune the device for individual cal...

UCSB researchers identify the mechanisms underlying salt-mediated behaviors in fruit flies

Researchers at UCSB have discovered the mechanisms behind salt-mediated behaviors in fruit flies, shedding light on sensory biology and its connection to human brain function. The study reveals that two distinct types of neurons compete to regulate behavioral outputs, with one type activated by low-salt and another by high-salt.

Nanoparticle opens the door to clean-energy alternatives

A new discovery by Penn State researchers may lead to the creation of cheaper clean-energy technologies. The team, led by Raymond Schaak, has found that a nickel phosphide nanoparticle can effectively trigger hydrogen production from water. This process is crucial for many energy-production technologies, including fuel cells and solar ...

Mount Sinai researchers succeed in programming blood forming stem cells

Researchers at Mount Sinai have made a breakthrough in programming blood-forming stem cells, which could lead to the development of patient-specific blood products. The study uses mouse fibroblast cells and identifies a combination of four genetic factors that can generate blood vessel precursor cells with hematopoietic cells.

Depression in postmenopausal women may increase diabetes and cardiovascular disease risk

A recent study found that postmenopausal women who experience depression or take antidepressant medication have a higher risk of developing diabetes and cardiovascular disease. The study, led by Dr. Yunsheng Ma, found associations between elevated depressive symptoms, increased insulin levels, and higher waist circumference.

Newly identified markers may predict who will respond to breast cancer prevention therapy

Researchers identified genetic variations associated with breast cancer risk among women on tamoxifen and raloxifene therapy. Women with favorable variations of the ZNF423 and CTSO genes are more likely to respond to prevention therapy, while those with unfavorable variations face a five-fold increased risk of developing breast cancer.
