UCLA-developed nanospears could make gene therapies safer, faster and more cost-effective

UCLA scientists have developed a new method that utilizes microscopic splinter-like structures called "nanospears" for the targeted delivery of biomolecules such as genes straight to patient cells. These magnetically guided nanostructures could enable gene therapies that are safer, faster and more cost-effective.

New study shows connection between coffee and cannabis

It's well known that a morning cup of joe jolts you awake. But scientists have discovered coffee affects your metabolism in dozens of other ways, including your metabolism of steroids and the neurotransmitters typically linked to cannabis, reports a new study from Northwestern Medicine.

E-cigarette use exposes adolescents to potentially cancer-causing chemicals

Adolescents who smoke e-cigarettes are exposed to significant levels of potentially cancer-causing chemicals also found in tobacco cigarettes, even when the e-cigarettes do not contain nicotine, according to a study by UC San Francisco researchers.

EPA ramps up efforts to create high-throughput endocrine disruptor assays

Exposure to endocrine-disrupting chemicals can cause health effects, such as reduced fertility and increased incidences of obesity and diabetes. Two decades ago, Congress directed the U.S. Environmental Protection Agency to screen substances for this activity.

NIH researchers explore genetic clocks to understand role of aging in neurodegeneration

To understand the link between aging and neurodegenerative disorders such as Alzheimer's disease, NIH scientists compared the genetic clocks that tick during the lives of normal and mutant flies.

Study: Soy-fed infants have differences in reproductive system tissues

Infants who consumed soy-based formula as newborns had differences in some reproductive-system cells and tissues, compared to those who used cow-milk formula or were breastfed, according to a new study.

ACEA Biosciences develops novel assay for rapid identification of endocrine-disrupting chemicals

Endocrine-disrupting chemicals are substances that interfere with the ability of endogenous hormones to regulate homeostasis via their cognate nuclear receptors.

Researchers seek to discover role of filter ventilation on addictive potential of cigarettes

Would banning ventilated filters on cigarettes protect public health? Scientists from multiple institutions, including a group of addiction neuroscience researchers from the Virginia Tech Carilion Research Institute, are gathering evidence under funding from the National Institutes of Health's National Cancer Institute to potentially inform a U.S. Food and Drug Administration (FDA) decision about whether to recommend design changes to filtered cigarettes.

E-cigarettes introduce same toxins into the body as traditional cigarettes

There has been a new trend of taking up vaping or using electronic cigarettes among teenagers. Some studies have shown that these electronic devices can help individuals quit smoking or at least cut down on smoking. Reports have found that middle schoolers and teenagers are taking up e-cigarettes.

Music may serve as extra tool to increase exercise time during cardiac stress test

If you exercise while listening to music, you may have noticed it can help boost your energy and make your workout seem quicker. Similarly, a study being presented at the American College of Cardiology's 67th Annual Scientific Session suggests listening to music during a standard cardiac stress test can help extend the time someone is able to perform the test, yielding important information about an individual's heart health and capacity for exercise.

Study unlocks big puzzle in familial breast cancer

Mutations in known breast cancer genes such as BRCA1 and BRCA2 are identified in only approximately 20 per cent of women who are offered genetic testing for familial breast cancer.

Researchers develop first analytical method to evaluate new cyanide and mustard gas antidote

To develop antidotes for chemical agents, such as cyanide and mustard gas, scientists need analytical methods that track not only the level of exposure but also how the drug counteracts the effects of the chemical.

Exposure to toxicants reduces when smokers switch from cigarettes to glo, study reveals

A clinical study conducted by scientists at British American Tobacco have revealed that when smokers switch completely from cigarettes to glo, their exposure to certain cigarette smoke toxicants is significantly reduced, in some cases to levels comparable to those seen in smokers who quit smoking completely.

Study sheds light on biological mechanisms that drive rare pediatric neurogenetic disorders

Researchers studying a rare genetic disorder that causes severe, progressive neurological problems in childhood have discovered insights into biological mechanisms that drive the disease, along with early clues that an amino acid supplement might offer a targeted therapy.

Researchers identify new nanostructure inside sperm tails

Human sperms are incredibly important for our reproduction. It would therefore be easy to assume that we have detailed knowledge of their appearance. However, an international team of researchers has now identified a completely new nanostructure inside sperm tails, thanks to the use of cryo-electron tomography.

Sleep disruptions in menopause correlated with hot flashes and depression

Sleep disruptions are one of the most commonly reported complaints among menopausal women. A new study of middle-aged women found that sleep problems vary across the stages of menopause, yet are consistently correlated with hot flashes and depression.

Food scientists develop rapid screening technique to detect pesticide residue in vegetables

Food scientists from the National University of Singapore developed a rapid and highly sensitive screening technique capable of detecting minute amounts of pyrethroids in vegetables, a common type of synthetic pesticide applied on agricultural crops. The innovative strategy makes use of magnetic nanoparticles to simplify pyrethorid extraction, reducing the screening process to under two hours.
