Driving can help diagnose Alzheimer’s | Digital Trends Spanish

According to research conducted by the University of Toronto, changes in the way you drive a vehicle over time could help diagnose Alzheimer's. Although the way of driving changes in all people over the years, in some there appear subtle differences in the way of controlling a vehicle which, according to scientists, would be related to the early stages of this disease. In the United States, a group of people over the age of 65 agreed to have their driving monitored for a year. The researchers found that it was possible to detect the onset of the disease without resorting to invasive and expensive medical procedures. Among the 139 people who were part of the study, medical tests had shown that half already had Alzheimer's disease at a very early or preclinical stage. The other half did...

This bat wears a mask for a particular reason | Digital Trends Spanish

This 2020, bats have become more popular and it is not only because of the next premiere of The batman (definitively postponed to 2022). This enigmatic animal has been associated with the genesis of the coronavirus, a pandemic that has the entire planet in check. We are constantly learning more about this creature that amazes us, and recently we have learned of a new species that can use a very appropriate "accessory" for these times. It's about the species Centurio senex, who uses a kind of mask on his face and whose main characteristics and behavior have been detailed in an observational study published in PLOS One. Preliminarily, the mask is thought to be part of a courtship ritual for males. This "accessory" would be incorporated into your face and would be made with excess sk...

First superplanet detected with a radio telescope | Digital Trends Spanish

An international team of astronomers has detected for the first time a cold brown dwarf, also known as a superplanet or failed star, using a radio telescope. The discovery, which was designated BDR J1750 + 3809, is the first substellar object to be detected through radio observations. Until now, brown dwarfs have largely been found from studying the infrared sky. The superplanet, also called Elegast, was first identified using data from the Low Frequency Array Telescope (LOFAR) in the Netherlands, and was later detected by a pair of observatories on Mauna Kea on the island of Hawaii. ASTRON / DANIELLE FUTSELAAR Finding such bodies with radio telescopes is a breakthrough, because it shows that astronomers can detect objects that are too cold and faint to be discovered in infrared st...

Eating Early Wouldn’t Help Weight Loss | Digital Trends Spanish

Restricting meals earlier in the day does not affect the weight of a group of overweight adults with diabetes, according to a study carried out at Johns Hopkins University. The results of this discovery will be presented at the scientific sessions of the American Heart Association that will take place this week. "We have long wondered whether eating during the day affects how the body uses and stores energy," said study author Dr. Nisa M. Maruthur, associate professor of medicine, epidemiology and nursing. from Johns Hopkins University in Baltimore. Together with her colleagues, the professional followed a group of 41 overweight adults during a 12-week study. A portion of the adults followed a time-restricted eating pattern, consuming 80% of their calories before 1pm. The rest of t...

The consumption of chili could help you live longer | Digital Trends Spanish

Good news for those who consume ají (chili) frequently. A investigation affirms that the consumption of the traditional pepper or chili pepper, as it is known in some countries, would allow people to live longer. Not only that, it would also greatly reduce the risk of dying from cardiovascular disease or cancer. The study will be presented soon in the scientific sessions of the American Heart Association, and for its realization, previous studies were taken into account that affirmed that the pepper has an anti-inflammatory, antioxidant, anti-cancer and regulating effect of glucose in the blood. How did they find out? For the present study, the health records of more than 570 thousand patients from the United States, China, Iran and Italy were analyzed, in order to compare the res...

Gold mine wastewater to combat COVID-19 | Digital Trends Spanish

They may not look good or look good, but analysis of the wastewater could provide researchers with important information about COVID-19. They can be, for example, a premature indicator of the existence of an outbreak of the disease, as well as provide information on the effectiveness of the adoption of quarantine by a population. "Wastewater is really a gold mine for information," says Jordan Peccia, a Yale professor of chemical and environmental engineering. If researchers can identify traces of COVID-19 in sewage sludge, they may be able to identify outbreaks and better understand how the virus spreads. For scientists, the concentration of COVID-19 RNA per milliliter of sewage sludge can indicate the presence or absence of the disease, as well as the way in which it spreads, eith...

Important finding about neurons and bad behavior | Digital Trends Spanish

A recent study carried out by the University of Helsinki demonstrated how different genetic control mechanisms can define the identity of neurons during development in the brainstem. The researchers' work also showed that a failure in the differentiation of brain stem neurons could lead to behavioral abnormalities, as well as hyperactivity and attention deficit. The team in charge set out to find out what brain stem neurons look like, how they develop in the embryonic brain, and how their developmental defects are reflected in brain activity and behavior. Although the mammalian brain is large, its activity is controlled by a small number of neurons. Many of them are found in the brain stem, which is a part conserved through evolution that controls mood, as well as motivation and mo...

Flu Vaccine Could Reduce COVID-19 Infection | Digital Trends Spanish

Researchers and medical officials are gathering information in the hope of finding a cure for the coronavirus, or at least an effective way to reduce the risk of infection. We still know little about this new health threat so any discovery may be useful, even if it has not yet been confirmed. Preliminary research suggests that a flu virus vaccine can also cause the body to produce broad molecules that fight infection and the virus causing the pandemic. Mihai Netea, an infectious disease immunologist at Radboud University Medical Center in the Netherlands, checked his hospital databases to see if medical officials who got flu shots during the 2019-2020 season had more or less likely to get SARS-CoV-2. He and his team found that workers who received the flu vaccine were 39 percent le...

Sponge can turn cooking oil into biodiesel | Digital Trends Spanish

Scientists from the Royal Melbourne Institute of Technology (MIT University) have succeeded in developing a tiny sponge capable of turning traditional cooking oil into inexpensive biodiesel. This fluffy material is a new type of ultra-efficient catalyst that is used to convert complex molecules into raw materials. The team in charge describes it as "the first of its kind", for its ability to carry out a series of different chemical reactions within a material. "Catalysts that can perform multiple simultaneous reactions have been developed previously, but these approaches offer little control over chemistry and tend to be inefficient and unpredictable," explains Karen Wilson, researcher and co-director of the study published in Nature Catalysis. The sponge-like catalyst is micron-si...
