Impossible is nothing: Spanish engineers build combustion engine with no exhaust emissions

Posted by in categories: health, sustainability, transportation

Spanish scientists are working on an internal combustion engine that does not pollute the environment. Will the new technology change the future of emission-free transport, which until now has been associated with electrification? Two prototypes will soon be presented.

Until recently, it seemed that combustion vehicles, alongside EVs and vehicles that use biofuels, were not participating in the ongoing ‘race’ for sustainable transport. But this has changed, thanks to Spanish scientists from the Technical University of Valencia (Universitat Politècnica de València, UPV) who are working on an emission-free internal combustion engine.

The Spanish scientists have designed a ‘revolutionary’ internal combustion unit that does not generate gases that are harmful to health or carbon dioxide (CO2), and which also stands out for its high efficiency and complies with the emission regulations planned for 2040. According to the Valencian Innovation Agency, which co-financed the project, the first two prototype engines will come to light in the coming months.

New Study Unveils Serotonin’s Key Role in Fertility and Depression

Posted by in categories: biotech/medical, health, neuroscience

Scientists from Nagoya University in Japan have identified the role of serotonin neurons in linking glucose availability to reproductive health. Their research demonstrates how elevated glucose levels stimulate serotonergic neurons, leading to the release of serotonin, which in turn activates kisspeptin neurons responsible for reproductive hormone release. These findings explain why poor nutrition affects fertility and suggest potential treatments for depression-induced infertility through the use of selective serotonin reuptake inhibitors (SSRIs).

Scientists from Nagoya University in Japan have clarified the connection between energy levels and fertility in both animals and humans. They discovered that signaling from serotonin neurons plays a crucial role in maintaining reproductive function by detecting glucose availability, which in turn enhances the release of the reproductive hormone gonadotropin. These findings also offer an explanation for the reduced fertility seen in individuals with depression and suggest potential treatments. The study was published in Scientific Reports.

People who lack sufficient nutrition encounter problems with their reproductive health. For example, ballet dancers can experience menstrual disruptions, and women who fast can struggle to conceive. According to a new study led by Designated Associate Professor Sho Nakamura and Professors Hiroko Tsukamura and Satoshi Ohkura, one of the main factors that affect a person’s reproductive health is glucose availability.

Cesarean Section Reduces Measles Vaccine Efficacy

Posted by in categories: biotech/medical, health

Cesarean section or C-section is a surgical procedure that delivers a baby through an abdominal incision. It is commonly used when the physicians believe it is a safer route for the parent, baby, or both. Cesarean section has appeared throughout history including Ancient Greece, India, Egypt, and Rome. There are even passages on cesarean section in different religious texts. It is believed that the name was attributed to the way Juluis Caesar was born. However, in Ancient Rome a cesarean section was only performed if at the time of birth, the mother was fatally ill and could not deliver naturally. It has been recorded that Julius Caesar’s mother was present during his life, therefore, historians believe he was not delivered through a cesarean section. Medical historians now believe the term originated from a decree in which Julius Caesar ordered women fated by birth to have a cesarean section which in Latin is “Caesones”. To this day, it is still incompletely understood where the name originated.

Cesarean sections are now routinely performed, and the procedure is well established. Interestingly, long-term effects of cesarean sections are not well known. Previously physicians noted no difference in health outcomes between children born through vaginal birth or cesarean section. Recently, however, a research group at the University of Cambridge found that a single dose of the measles vaccine is 2.6 times more likely to not be effective in children born through cesarean section. Unfortunately, a lack of vaccine efficacy leads to weakened immunity due to an inadequate number of antibodies produced to fight infection. While the first vaccination produced little efficacy, researchers demonstrated that a second measles vaccine was comparable to vaginally born children. More specifically, the vaccine was effective and produced the necessary antibodies to fight infection.

The recent paper published in Nature Microbiology by Dr. Henrik Salje, concluded the long-term effects of cesarean section delivery. Researchers suggest an increased risk of measles outbreak among children that were born through cesarean section and had only one measles vaccination. Salje and others explain that lack of vaccine efficacy is linked to the infants’ gut microbiome. It is well established that children receive great exposure to healthy microbes through vaginal birth, which boosts their immune systems. By avoiding microbe exposure through cesarean section, the infant loses critical immune protection.

Maximizing DNA Yield for Biobanking Applications

Posted by in categories: biotech/medical, genetics, health, robotics/AI

With advances in genomics research, personalized medicine, and sequencing-based technologies, there is a necessity for purification of high-quality genomic DNA from large volumes of blood. The rapidly growing landscape of biorepositories that store large amounts of DNA from an enormous number of biospecimens further fuels this need to find optimized solutions for reliable purification of DNA. The information derived from the purified DNA is crucial to health science research and facilitates drug discovery, biomarker discovery, clinical implementation projects, etc. For the success of these analyses and to derive relevant information, DNA extraction is the most critical step and must meet the criteria of extraction speed, yield and quality, as well as reproducibility. Many nucleic acid purification kits and automation workflows for processing blood samples in the volume range of 100–250 μL exist, but not many convenient, automated options exist for volumes as high as 2 mL without sample splitting. To fill this opening, Omega Bio-tek has developed a semi-automated solution on the MagBinder® Fit24 to extract DNA from large volumes of fresh or frozen blood. Here, we provide background information on biobanks, as well as present the solution Omega Bio-tek has developed for DNA extraction from large volumes of whole blood.

A biobank is a specialized repository that systematically collects, processes, stores, and manages biological samples for use in medical research and treatments. The primary purpose of a biobank is to provide a centralized and organized resource of high-quality biological materials, such as blood or tissue, along with relevant clinical and demographic data1. These invaluable assets are at the center of advancements in cancer treatments, biomarker discovery, and understanding genetic factors for disease. At a high level, biobanks can be classified by two categories1:

Increasing use of renewable energy in US yields billions of dollars of benefits

Posted by in categories: climatology, health, sustainability

They found emissions of SO2 and NOx – both linked to increased asthma risk and a variety of other health issues – decreased by a total of 1m metric tons over that three-year period.

To determine the impact of that reduction on public health, the authors “used air quality models to track the population exposed to pollution from power plants”, Millstein said. They also employed epidemiological research to examine the effects of those emissions, and quantified the benefits by using an Environmental Protection Agency dollar value establishing the value of reducing the risk of early death across the population, he said.

All told, the emission reductions from SO2 and NOx provided $249bn of climate and health benefits to the US, the authors found – a figure Millstein said he found was “noteworthy”

About 90% of US adults are on the way to Heart Disease, study suggests

Posted by in categories: biotech/medical, health

Nine of 10 American adults are in the early, middle or late stages of a syndrome that leads to heart disease, a new report finds, and almost 10% have the disease already.

“Poor cardiovascular, kidney, and metabolic health is widespread among the U.S. population,” concludes a team led by Dr. Muthiah Vaduganathan of Brigham and Women’s Hospital and Harvard Medical School in Boston.

Researchers looked specifically at rates of what the American Heart Association has dubbed cardiovascular, kidney and metabolic (CKM) syndrome—interrelated factors that progress with time and, if left unchecked lead to heart disease.
