Adding another dimension to a cell culture model for pulmonary arterial hypertension
Researchers in LÃ¡slÃ³ ForrÃ³'s lab at EPFL, Switzerland, are working on a membrane made of titanium oxide nanowires, similar in appearance to filter paper but with antibacterial and antiviral properties. Their material works by using the photocatalytic properties of titanium dioxide: when exposed to ultraviolet radiation, the fibers convert resident moisture into oxidizing agents such as...
Alport syndrome: Research highlights link between genotype and treatment effectiveness
Pulmonary arterial hypertension is a rare disease in which excessive proliferation of the cells of pulmonary arterial walls obstructs the blood flow in the lungs. A group of scientists based in Okayama, Japan, has now used 3D cell culture technology to recapitulate the pathogenetic process involved in pulmonary arterial hypertension in the laboratory, with potential applications in drug testing.
Chemotherapy for rare cancer fine-tuned with organoids
A large-scale analysis of the clinical characteristics of Alport syndrome in Japanese patients has revealed for the first time in the world that the effectiveness of existing treatment with ACE inhibitors and/or angiotensin receptor blockers (RAS inhibitors) varies depending on the type of mutation in the syndrome's causal gene (COL4A5).

Experts urge evaluation of diet at routine check-ups
A nanomedicine-based strategy for chemo-immunotherapy (CIT) of glioblastoma (GBM), which has the worst prognosis among brain tumors, was successfully developed.
Hubble makes the first observation of a total lunar eclipse by a space telescope
Unhealthy dietary patterns are a leading cause of heart disease and stroke as well as other chronic diseases.Clinician-delivered diet counseling can improve diet behaviors and heart disease risk factors.Quick, simple dietary assessment tools can be a part of routine office visits and integrated into electronic health records for follow-up.
Huge ring-like structure on Ganymede's surface may have been caused by violent impact
Taking advantage of a total lunar eclipse, astronomers using the NASA/ESA Hubble Space Telescope have detected ozone in Earth's atmosphere. This method serves as a proxy for how they will observe Earth-like planets around other stars in the search for life. This is the first time a total lunar eclipse was captured from a space telescope and the first time such an eclipse has been studied in...
Lead poisoning could reduce gene expression in humans
Image data reanalysis by researchers from Kobe University and the National Institute of Technology, Oshima College have revealed that ancient tectonic troughs are concentrically distributed across almost the entire surface of Ganymede. Computer simulation results suggest that this giant crater could have resulted from the impact of an asteroid with a 150km radius. If so, this the largest impact...
Machine learning research may help find new tungsten deposits in SW England
Scientists have unveiled a correlation between high blood lead levels in children and methylation of genes involved in haem synthesis and carcinogenesis, indicating a previously unknown mechanism for lead poisoning.
New reporter mouse strain offers powerful genetic tool to identify P2X2-expressing cells
Geologists have developed a machine learning technique that highlights the potential for further deposits of the critical metal tungsten in SW England.
New Zealand's Southern Alps glacier melt has doubled
University of South Florida Health Morsani College of Medicine researchers created a reporter mouse strain in pursuit of a new way to answer an old question: Is purinergic receptor gene P2X2 expressed in particular populations of sensory nerve cells? They were surprised, but encouraged, to find P2X2 expressed in a very limited subset of neurons.
NSD2 enzyme appears to prevent cellular senescence
Glaciers in the Southern Alps of New Zealand have lost more ice mass since pre-industrial times than remains today, according to a new study led by the University of Leeds. The study mapped Southern Alps ice loss from the end of the Little Ice Age -- roughly 400 years ago -- to 2019. It found that relative to recent decades, the Southern Alps lost up to 77% of their total Little Ice Age glacier...
Origins of life: Chemical evolution in a tiny Gulf Stream
Using comprehensive genetic analysis, Kumamoto University researchers have found, for the first time, that the NSD2 enzyme blocks cell aging. Inhibition of NSD2 function in normal cells leads to rapid senescence of cells and the amount of NSD2 in senescent cells is significantly reduced. It is hoped that these findings will help clarify the mechanisms of aging, the development of control methods...
Potentially predictive humoral immune response markers in COVID-19 patients
Chemical reactions driven by the geological conditions on the early Earth might have led to the prebiotic evolution of self-replicating molecules. Scientists at Ludwig-Maximilians Universitaet (LMU) in Munich now report on a hydrothermal mechanism that could have promoted the process.
Renewables in Europe: Land requirements can be reduced at low cost
Results of partnership between the Ragon Institute of MGH, MIT and Harvard and UW Medicine identify five markers of the humoral immune response that may be able to predict COVID-19 patient outcomes.
Researchers discover how plants distinguish beneficial from harmful microbes
Transitioning our energy supply from coal, oil and gas to wind and solar power is feasible. However, renewables require more land than conventional forms of energy generation. A new study explores the options to reduce the land requirements of a fully renewable energy supply in Europe and their possible impact on the cost of electricity.
Smartwatch tracks medication levels to personalize treatments
Plants recognize beneficial microbes and keep harmful ones out, which is important for healthy plants production and global food security. Scientists have now discovered how legumes use small, well-defined motifs in receptor proteins to read molecular signals produced by both pathogenic and symbiotic microbes. These remarkable findings have enabled the researchers to reprogram immune receptors...
Stellar egg hunt with ALMA
Engineers at the UCLA Samueli School of Engineering and their colleagues at Stanford School of Medicine have demonstrated that drug levels inside the body can be tracked in real time using a custom smartwatch that analyzes the chemicals found in sweat.

Study finds parents can help kids eat healthier by knowing their own sense of self-control
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) took a census of stellar eggs in the constellation Taurus and revealed their evolution state. This census helps researchers understand how and when a stellar embryo transforms to a baby star deep inside a gaseous egg. In addition, the team found a bipolar outflow, a pair of gas streams, that could be telltale evidence of a...
Success in promoting plant growth for biodiesel
Young children naturally like sugar and salt in food and develop food preferences based on what their parents serve them, but new research suggests that how parents view self-regulation also is a contributing factor. The research explored the underlying dynamics of parental food preferences and how they are passed along to children by example at family mealtime.
Test accurately IDs people whose gonorrhea can be cured with simple oral antibiotic
Scientists of Waseda University in Japan succeeded in promoting plant growth and increasing seed yield by heterologous expression of protein from Arabidopsis (artificially modified high-speed motor protein) in Camelina sativa, which is expected as a useful plant for biodiesel. The study is expected to apply to other plant resources for biodiesel, such as corn, rice, and sugar cane.
The costs and benefits of addressing customer complaints
A test designed by UCLA researchers can pinpoint which people with gonorrhea will respond successfully to the inexpensive oral antibiotic ciprofloxacin, which had previously been sidelined over concerns the bacterium that causes the infection was becoming resistant to it.
Developing a strategy to achieve an optimal recovery-loyalty yield is more advantageous than adopting the mantra that the customer is always right.
