Alzheimer’s blood test optimized to detect disease before symptoms

Alzheimer’s blood test optimized to detect disease before symptoms

A newly published study details the optimization of a previously developed blood test for detecting Alzheimer's disease. Though the original test could successfully detect the disease's presence before symptoms started, the accuracy wasn't quite high enough and there were too many false positives. By adding a second test into the mix, researchers have been able to improve both of those issues.

Study reveals how to trick nearly unbeatable brain lie detectors

Study reveals how to trick nearly unbeatable brain lie detectors

A new study has revealed two relatively simple methods that can be used to trick a brain imaging lie detector, which utilizes a functional MRI (fMRI) machine instead of a traditional polygraph system. Unlike techniques used to evade normal lie detection methods, researchers found that someone undergoing a brain imaging lie detection test can drastically reduce the results accuracy with two thought techniques.

Researchers make a breakthrough in bioprinting human organs

Researchers make a breakthrough in bioprinting human organs

Bioengineers at Rice University have made a breakthrough in bioprinting of tissues. The team has been able to create entangled vascular networks that can mimic the body's natural passageways for blood, air, lymph, and other vital fluids. Scientists created a proof-of-principal that is a hydrogel model of a lung-mimicking air sac that has airways delivering oxygen to surrounding blood vessels.

Researchers bet you’ll eat maggots if they’re disguised in food

Researchers bet you’ll eat maggots if they’re disguised in food

A number of past studies have warned that the world's current meat consumption habits -- including the types of meat consumed -- are unsustainable. 'Alternative meats,' namely insects, are often cited as the protein of the future, but many Westerners express a reluctance toward eating them. That may change, researchers speculate, if the insects are offered in the form of familiar pre-packaged food products.

Walnuts may lower blood pressure, but only with this diet tweak

Walnuts may lower blood pressure, but only with this diet tweak

Walnuts are an excellent source of omega-3 fatty acids and are often recommended as a healthy fat source for health-conscious dieters. The small nuts may be an excellent dietary choice for individuals at risk of cardiovascular disease, as well, at least according to a new study out of Penn State. Researchers found that eating walnuts combined with a simple diet adjustment may reduce blood pressure levels.

Beyond Meat IPO rages as fake beef health research mounts

Beyond Meat IPO rages as fake beef health research mounts

The appetite for Beyond Meat looks pretty much set, with the freshly-floated plant-based meat substitute company causing a ruckus on the stock exchange this week. The IPO came amid fresh research suggesting replacing red meat with a plant-based protein alternative can have a significant impact on health risks.

Autism can be reliably detected at ages as young as 14 months

Autism can be reliably detected at ages as young as 14 months

Autism Spectrum Disorder (ASD) screenings can begin as young as 14 months old, according to a new study, while retaining high accuracy. This is a few months earlier than the minimum 18-month-old age recommendation for ASD screenings, which happen at regular doctor visits. The findings were detailed in a study recently published in the JAMA Pediatrics journal.

Measles outbreak passes 700 cases as vaccination gets unexpected support

Measles outbreak passes 700 cases as vaccination gets unexpected support

The CDC released its most recent measles number on Friday, revealing that more than 700 cases have now been confirmed in the United States. The latest figure underscores the rapid rise of this highly contagious disease, which is at the highest it has been in any single year since the disease was declared eliminated in 2000. Amid the concerning outbreak comes vaccination support from a very unlikely source.

Moderate morning exercise has surprising workday benefits

Moderate morning exercise has surprising workday benefits

Morning exercise may offer benefits throughout the workday, according to a new study out of Australia. In addition to boosting cognitive performance, the team found that breaking up the typical 8-hour workday with regular short walks can have a positive effect on one's short-term memory, contributing to an overall more productive day. The study hints that different exercise patterns may have their own special effects on different parts of one's overall cognition.

The FDA just approved this futuristic lung transplant technology

The FDA just approved this futuristic lung transplant technology

The Xvivo Perfusion System looks like a medical device out of a science fiction movie, but it's real and it was just granted FDA approval. The technology opens the door to a greater number of lung transplants by enabling teams to evaluate and potentially approve donor organs that would otherwise be discarded. The system was previously approved under a humanitarian device exemption, but that limited the number of patients who could benefit from the technology.

Poor sleep, stress most damaging to people with common health issue

Poor sleep, stress most damaging to people with common health issue

Chronic stress and poor sleep quality are known to have negative effects on both short-term and long-term health, but a new study reveals that they're more serious for people who have a certain common health issue: high blood pressure. Combining the three issues results in a much higher risk of dying from cardiovascular disease, according to a new study, which warns that failing to address these conditions may result in major damage to one's long-term health.

Study finds profound psychedelic trips can offer long-term healing

A new study out of Johns Hopkins University School of Medicine has found that profound psychedelic trips and spontaneous drug-free instances of experiencing 'ultimate reality' can have long-term healing and otherwise beneficial effects on people. Such experiences are often reported by individuals who have taken LSD and psilocybin mushrooms.
