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.”
We all know that doing sports is very important, both for health and for a beautiful body. But at the moment when we decide to finally take the path, we are faced with the question: what kind of sport is right for me? So, let’s start with the fact that a lot of people are jogging in the morning. It is worth saying that this is the most accessible kind of sport. If you seek in sport not only health but good mood for a whole day, then the morning run is what you need. Do not forget about the special footwear, its choice will largely determine the benefit of the morning run.
The next option is swimming. This sport is suitable for those who like to combine business with pleasure, because water procedures for many are an excellent holiday, and sports loads in the water – this is just what helps to bring yourself in tone.
Another very interesting activity is tennis, the effect here can only be achieved if you start with a coach, and you can add to the disadvantages that professional tennis is a very expensive sport. The fact is that you will need good rackets, a special room for the game, as well as a few lessons from the master.
The most common option today for sports is to go to the gym. Often people choose this option when they just want to get a beautiful body. But in fact it turns out that many become very bored in the gym. The fact is that when you are engaged in some particular sport, you have the excitement, for example, to swim to the shore first, to score a goal. As for simple iron simulators, here the desire is only one thing – to get the effect of such torture.
Another kind of very effective sport is cycling. You probably know how to ride from childhood and do not need training, you do not need to buy any special equipment, look for a room. A bicycle is also very useful for those who want to lose weight a little, because cycling is a great way to burn fat.
Well, the easiest kind of sport is a simple dance. Of course, it’s not about the movements that you do in the morning in front of a mirror. We are talking about professional dance classes, everyone can choose a sphere to their liking, someone will make a choice in favor of ballroom dancing, someone will choose modern hip-hop directions, in fact, it’s not so important. Especially dancing is good for women, because the dance helps to make perfect figure, burning fat and tightening all forms.
According to a new study, performed by the French scientists, people who eat a lot of fruit and vegetables have up to 30% less risk to experience the severe symptoms of asthma.
For their research, a team of scientists studied approximately 35,000 people comparing their diets and the symptoms of their asthma. The analysis of the received data showed that men who eat a more healthy diet tend to have a 30% lower risk to experience the symptoms of asthma. At the same time, women’s risk was 20% lower.
Lead researcher of the study Dr. Roland Andrianasolo says: “Our results strongly encourage the promotion of healthy diets for preventing asthma symptoms and managing the disease.”
A human immune system consists of various cells, tissues, and proteins. In the system, they carry out the processes in our body that fight with pathogens — viruses, bacteria, and foreign bodies. When a pathogen comes into contact with the immune system, the latter releases antibodies to attack pathogens and kill them. The following fifteen foods will help you to boost your immune system:
A new study from the US suggests that poor air quality and diabetes are closely connected. Researchers from Washington University School of Medicine in St. Louis in collaboration with the Veterans Affairs St. Louis Health Care System in Missouri performed the study.
To achieve the set study goal, a team of researchers analyzed the influence of air pollution on a group of United States veterans with no previous history of diabetes. The followed the participants of the study for averagely 8.5 years.
Senior author of the study Dr. Ziyad Al-Aly says: “Our research shows a significant link between air pollution and diabetes globally. We found an increased risk, even at low levels of air pollution currently considered safe by the U. S. Environmental Protection Agency (EPA) and the WHO.”
A recent research, published in the European Respiratory Journal, finds that sleep apnea, a common disorder that interferes with the breathing while sleeping, is connected to the changes in brain structure similar to changes seen in early dementia.
For the study, 83 participants were involved with the age from 51 to 88. They reported memory and mood problems to their doctors. None of them was diagnosed with obstructive sleep apnea (OSA) They underwent memory tests and MRI brain scans.
Having analyzed the received data, the scientists concluded that a low level of oxygen in blood during sleep was associated with the loss of thickness of the right and left temporal lobes of the brain. These brain structures play important role in memory processes and proved to be changed in dementia.

A new Spanish study that eating a handful of nuts, such as almonds, hazelnuts, and walnuts, improves the sperm count by 16%. Also, nuts boost sperm movements by 6%, its survival by 4% and shape by 1% that are all related to male fertility.
For the study, a team of researchers from the University Rovira I Virgil, Tarragona, Spain, analyzed 119 healthy men aged between 18 and 35 years for 14 weeks. The results of the analysis showed that a handful of nuts on a daily basis reduces sperm’s DNA damage.
Author of the study Dr. Albert Salas-Huetos says: “Evidence is accumulating that healthy lifestyle changes such as following a healthy dietary pattern might help conception and of course, nuts are a key component of a Mediterranean healthy diet.”
The findings of the study were presented at the European Society of Human Reproduction and Embryology in Barcelona, Spain.
