Raised sensitivity to bitter tastes might be an indicator of higher risk of cancer in women, according to a new research, conducted by scientists at the College of Agriculture Sciences of Pennsylvania State University in State College (US) in association with a team of researchers from Leeds University (UK).
For the study, the researchers collected data via the UK Women’s Cohort Study, founded in 1995 by scientists at Leeds University. The researchers split women into 3 groups according to their sensitivity to bitterness: “super-tasters”, “tasters,” and “non-tasters.” The analysis of the received data showed that “super-tasters” and “tasters” were at higher risk of cancer than those who couldn’t taste bitterness.
Lead researcher Joshua Lambert explains: “The difference in cancer incidence between the women with the highest bitter-taste sensitivity and those with the lowest was striking. Super-tasters had about a 58 percent higher risk of cancer incidence and the tasters had about a 40 percent higher risk of developing cancer, compared to women who were classified as non-tasters.”
A new study from the Stevens School of Business in New Jersey, USA, finds that even coffee scent can sharpen the brain under certain conditions.
In the study, 114 students were involved. The participants were divided into two group and both had to answer mathematical questions. One group has been exposed to a coffee smell during the study. The scent was free from caffeine and other stimulants.
The researchers also executed a follow-up survey. They asked questions of 208 individuals not involved in the first test and found that a coffee scent was associated with being more alert and energetic, compared with other scents such as flowers, or with no scent.
Lead researchers of the study Adriana Madzhrov says: “Olfaction is one of our most powerful senses. Employers, architects, building developers, retail space managers and others, can use subtle scents to help shape employees’ or occupants’ experience with their environment.”
A large-scale review of clinical trials for the past 25 years confirms that walnuts are the great choice for people who want to support their cardiovascular health.
The scientists reviewed 26 randomized studies with 1,059 participants in total whose age was from 22 to 75. The benefits of a diet rich in walnuts were compared to low-fat, Western, Mediterranean, and Japanese diets.
The analysis showed that a diet rich in walnuts had 3.25% greater reduction in total cholesterol levels, 3.73% greater decrease in LDL cholesterol, and 5.52% greater reduction of triglycerides.
Dr. Michael Roizen, the chief wellness officer in the Department of Preventive Medicine at the Cleveland Clinic in Ohio, says: “This updated review further strengthens the case that enjoying walnuts is a great (and tasty) way to add important nutrients to your diet while supporting the health of your heart.”
A new study, published in the medical journal JAMA, finds that the more teenagers involved in social media, the higher their risk is to develop the symptoms of attention deficit hyperactivity disorder (ADHD). These symptoms may include inattention, hyperactivity, restlessness or impulsivity that is more severe, frequent or debilitating compared to normal.
In the study, 2,587 students from 10 high schools across Los Angeles County, USA, were included. The participants’ age was from 15 to 16 years. Nobody of them had significant symptoms of ADHD at the beginning of the study. They participated in the study for over 2 years.
The analysis of the received data showed that averagely 9.5% of the participants who were engaged in seven high-frequency digital media activities reported symptoms of ADHD; 10.5% of those who reported engaging in all 14 high-frequency digital media activities reported ADHD symptoms.
Scientists from the Check Republic discovered the evidence that ticks may prefer attacking people with a certain blood type. Tick, the blood-sucking parasites, can carry various bacteria, including bugs that cause the Lyme disease.
In the course of study, the researchers dropped a tiny sample of blood from blood types A, B, AB, and O onto a sterile layer of filter paper on a Petri dish in the laboratory. The analysis of the received results showed that the ticks preferred type A blood in the majority of cases — 36% of the tick chose the sample. Type B was found to be least “favorite” — only 15% of the parasite chose the respective samples.
Lead researcher Dr. Alena Zakovska says: “The presented study demonstrated that blood group might be one of the factors determining the feeding preferences of Ixodes ricinus ticks.”
A team of scientists from the Swinburne University of Technology in Australia finds that cinnamon may help in treating resistant bacterial infections breaking up their biofilms — sticky layers that are usually responsible for persistent infections that cannot be broken by antibiotics.
For experiments, the scientists used Pseudomonas aeroginosa, a bacterium commonly responsible for infections in people with weakened immune systems including patients with cancer, diabetes, or cystic fibrosis.
The lead researcher of the study Dr. Sanjida Topa says: “These findings definitely contribute to the search for novel antimicrobials. […] Fabrication of cinnamaldehyde for surface treatments, for example [to treat] skin infections, could be the first direct application.”
