Stimulating brain circuits promotes neuron growth in adulthood, improving cog...
16 May 2022 at 12:02pm
Targeting specific brain cells modulated memory retrieval and altered anxiety-like behaviors in mice. Essentially, scientists boosted the electrical activity between cells in the hypothalamus and the hippocampus to create new neurons -- an important process called neurogenesis.
New micro device injects a boost to IVF success
16 May 2022 at 9:40am
A research team has delivered a ground-breaking new micro-device to streamline the only fertility treatment procedure available for men with low sperm counts.
Electronic skin: Physicist develops multisensory hybrid material
16 May 2022 at 9:40am
Recently developed 'smart skin' is very similar to human skin. It senses pressure, humidity and temperature simultaneously and produces electronic signals. More sensitive robots or more intelligent prostheses are thus conceivable.
Perception-based nanosensor platform could advance detection of ovarian cancer
16 May 2022 at 9:39am
Ovarian cancer kills 14,000 women in the United States every year. It's the fifth leading cause of cancer death among women, and it's so deadly, in part, because the disease is hard to catch in its early stages. Patients often don't experience symptoms until the cancer has begun to spread, and there aren't any reliable screening tests for early detection.
Ethical challenges in microbiome research
16 May 2022 at 9:39am
A human rights activist and a group of anthropologists and human biologists are casting a critical lens on the way that microbiome research is conducted with Indigenous peoples.
Precursor of spine and brain forms passively
16 May 2022 at 9:39am
Researchers have conducted a detailed study of neurulation -- how the neural tube forms during embryonic development. They conclude that this happens less actively than previously thought. This also has implications for understanding defects such as spina bifida.
CRISPR-Cas9 gene editing approach can alter the social behavior of animals
16 May 2022 at 7:46am
New gene-editing techniques are shedding light on how hormones impact social behavior in animals and possibly, humans.
Cutting air pollution emissions would save 50,000 US lives, $600 billion each...
16 May 2022 at 7:14am
Eliminating air pollution emissions from energy-related activities in the United States would prevent more than 50,000 premature deaths each year and provide more than $600 billion in benefits each year from avoided illness and death, according to a new study.
Circuit model may explain how deep brain stimulation treats Parkinson's disea...
16 May 2022 at 5:17am
Stimulation of subthalamic nucleus interrupts a cycle of runaway beta-frequency rhythms and restores ability of interneurons to regulate rhythms in the brain's striatum, improving movement, study suggests.
Weights can be weapons in battle against obesity
16 May 2022 at 5:17am
Despite the commonly held belief aerobic exercise is essential for weight loss, a new study has found resistance training can have equally positive results -- in conjunction with reducing calorie intake.
Artery stiffness may predict Type 2 diabetes risk better than BP and standard...
16 May 2022 at 5:17am
Analysis of more than 11,000 people investigated whether high blood pressure or arterial stiffness may be a better predictor of future Type 2 diabetes risk. Results found that adults with increased arterial stiffness had a higher risk of developing Type 2 diabetes, regardless of their hypertension status when added to standard risk factors. More research is needed to determine the association among Type 2 diabetes, high blood pressure and arterial stiffness, and to provide insight into future prevention strategies to reduce the risk of Type 2 diabetes.
Smart pacifier developed to monitor infant health in the hospital
16 May 2022 at 5:17am
A wireless, bioelectronic pacifier could eliminate the need for invasive, twice-daily blood draws to monitor babies' electrolytes in Newborn Intensive Care Units or NICUs. This smart pacifier can also provide more continuous monitoring of sodium and potassium ion levels. These electrolytes help alert caregivers if babies are dehydrated, a danger for infants, especially those born prematurely or with other health issues. Researchers tested the smart pacifier on a selection of infants in a hospital, and the results were comparable to data gained from their normal blood draws.
Humans may have evolved to show signs of stress to evoke support from others
15 May 2022 at 8:32am
Showing signs of stress could make us more likeable and prompt others to act more positively towards us, according to a new study.
Robotic surgery is safer and improves patient recovery time
15 May 2022 at 8:32am
Robot-assisted surgery used to perform bladder cancer removal and reconstruction enables patients to recover far more quickly and spend significantly (20 per cent) less time in hospital, concludes a new clinical trial.
Hormonal changes during menopause are directly related to decline in cardiova...
15 May 2022 at 8:32am
Levels of bad cholesterol rise during menopause, and 10% of this increase is likely due to shifts in sex hormones. Women usually undergo menopause at the age of 48 to 52 years, leading to a decline in estrogen and increase in follicle-stimulating hormone (FSH). Menopause is thought to predispose women to heart disease since it typically develops 10 years later than in men, and risk rises after menopause.
