Abnormal biomarkers associated with obesity are identified in very young Latino children, study finds

In the United States, low-income, Latino youth are disproportionately affected by obesity with 25.8% of Latino youth aged 2-19 considered to have obesity, which is approximately two times more likely when compared to their non-Latino white counterparts. A higher level of obesity results in an increased risk of cardiometabolic diseases, which are a group of related diseases caused by an unhealthy lifestyle and/or an increased genetic predisposition. A new study by Allison McKay, RDN, department manager for the Department of Nutrition and Food Studies, identified elevated insulin, hemoglobin A1C, triglycerides, and other cardiometabolic ...

New targets for CAR-T cell therapy against acute myeloid leukemia through AI-assisted analysis

Unlike other forms of blood cancer, acute myeloid leukemia (AML) cannot currently be treated with CAR-T cell immunotherapy. The reason is that specific molecular targets with which certain immune cells could specifically target AML cells are lacking, which would permit the immune system to attack cancer. Two research teams of Professor Dr. Sebastian Kobold with Dr. Adrian Gottschlich from the Division of Clinical Pharmacology at LMU University Hospital Munich and Dr. Carsten Marr with Moritz Thomas from the Institute of AI for Health at Helmholtz Munich have now ...

The fat tax: Long-term, systemic antibiotic use for the treatment of adolescent acne can promote fat accumulation

A growing body of evidence is showing that the healthy gut microbiome – a community of microorganisms that live together in the gut – influences many aspects of human growth and development, especially during adolescence. While there are many physiologic changes during this time, one of the most outward facing, and sometimes distressing, is the development of acne. Most individuals treat their acne with topical therapies; however, around 25% of adolescents require systemic antibiotics, such as minocycline, to help to alleviate symptoms and clear up the skin. These systemic antibiotic ...

Scientists develop new concepts about the shape and dynamic nature of molecules

-With pictures- Scientists have demonstrated in a new study that carbon-based molecules can be much more dynamic than previously thought. When a carbon atom forms four bonds to different groups, the molecule can exist in two mirror image forms. These mirror image forms are vital in medicine because they have different biological activities. Usually, it is impossible to interconvert between these ‘enantiomers’ because to do so would require a bond to be broken, a process that needs too much energy. The researchers ...

Minke whales are as small as a lunge-feeding baleen whale can be

A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient “lunge-feeding” strategy that enabled the blue whale to become the largest animal on Earth. Lunge feeding whales accelerate toward a patch of prey, engulf a huge volume of water, and then filter out the prey through the baleen plates in their mouths. This strategy is used by the largest group of baleen whales, known as rorquals, which includes blue, fin, humpback, and minke whales. The ability ...

UK scientists discover a new way to help prevent breast cancer ‘time bomb’

Scientists have discovered why breast cancer cells that have spread to the lungs may ‘wake up’ following years of sleep - forming incurable secondary tumours. Their research, funded by Breast Cancer Now, reveals the mechanism that triggers this breast cancer 'time bomb' – and suggests a strategy to defuse it. Patients with oestrogen receptor positive (ER+) breast cancer – the most common type – have a continued risk of their cancer recurring in another part of their body for many years or even decades after their original ...

The right cocktail of gut enzymes can stop c. diff in its tracks

Not all probiotics are created equal. In a new study, researchers found that certain enzymes within a class known as bile salt hydrolases (BSHs) can restrict Clostridioides difficile (C. diff.) colonization by both altering existing bile acids and by creating a new class of bile acids within the gut's microbial environment. The work could lead to “designer” probiotics that protect against disease by introducing specific BSHs to the gut after antibiotic treatment. Selecting the right suite of BSH-producing bacteria is critical, because the study found that interactions between BSHs and bile acids ...

Magnetism fosters unusual electronic order in quantum material

HOUSTON – (March 13, 2023) – Physicists were surprised by the 2022 discovery that electrons in magnetic iron-germanium crystals could spontaneously and collectively organize their charges into a pattern featuring a standing wave. Magnetism also arises from the collective self-organization of electron spins into ordered patterns, and those patterns rarely coexist with the patterns that produce the standing wave of electrons physicists call a charge density wave. In a study published this week in Nature Physics, Rice University physicists Ming Yi and Pengcheng Dai, and many of their collaborators from the 2022 ...

IPK researcher use TurboID to uncover new meiotic proteins in Arabidopsis thaliana

During meiosis, reshuffling of genetic information between homologous chromosomes through meiotic recombination creates variable gametes and hence genetic variation in offsprings. Meiotic recombination occurs in the context of the meiotic chromosome axis, a proteinaceous structure along which sister chromatids are arranged in a loop base array during prophase I. Data across organisms suggests meiotic chromosome axis serving as a scaffold for meiotic recombination. In the model plant A. thaliana, the axis associated proteins ASY1 and ASY3 are critical for synapsis and meiotic recombination. “Due to the key role of axis proteins such as ...

Superstore MXene: New proton hydration structure determined

One of the biggest challenges for a climate-neutral energy supply is the storage of electrical energy. Conventional batteries can hold large amounts of energy, but the charging and discharging processes take time. Supercapacitors, on the other hand, charge very quickly but are limited in the amount of stored energy. Only in the last few years has a new class of materials been discussed that combines the advantages of batteries with those of supercapacitors, named pseudocapacitors. Promising materials: Pseudocapacitors Among pseudocapacitive materials, so-called MXenes consisting of a large family of 2D transition metal carbides and nitrides appear particularly promising. Their structure ...

Entire populations of Antarctic seabirds fail to breed due to extreme, climate-change-related snowstorms

The arrival of the new year is a prime time for Antarctic birds like the south polar skua, Antarctic petrel, and snow petrel to build nests and lay their eggs. However, from December 2021 to January 2022, researchers did not find a single skua nest on Svarthamaren, one of the regions where the birds go to raise their young. Similarly, the number of Antarctic petrel and snow petrel nests dropped to almost zero. In these regions, climate change caused snowfall and snow accumulation to be significantly higher than in previous years. Now, a study published on March 13 in the journal Current Biology shows that these unusually strong snowstorms ...
