Lung images of twins with asthma add to understanding of the disease
In a case study published today, researchers used a specialized MRI technique in a set of twins with asthma. While the twins are non-identical, the researchers found that they actually had identical ventilation defects in the same upper left lung segment, which stayed the same over the duration of the seven year study.
Machine learning helps scientists measure important inflammation process
Inflammation is a hallmark of many health conditions, but quantifying how the underlying biology of inflammation contributes to specific diseases has been difficult. For the first time, UNC School of Medicine researchers and colleagues now report the development of a new technology to identify white blood cells called neutrophils that are primed to eject inflammatory DNA into the circulation via a process called NETosis.
Mapping the energy transport mechanism of chalcogenide perovskite for solar energy use
Researchers from Lehigh University have, for the first time, revealed first-hand knowledge about the fundamental energy carrier properties of chalcogenide perovskite CaZrSe3, important for potential solar energy use. They have published their findings in NPJ Computational Materials.
Medical marijuana cards often sought by existing heavy users
Young adults who seek enrollment in state medical marijuana programs are often those who already use heavily rather than those with mental or physical issues that could be addressed by the drug.
Mindfulness training may help lower blood pressure, new study shows
A study at Brown University finds that mindfulness could reduce blood pressure by enhancing attention control, emotion regulation and self-awareness of both healthy and unhealthy habits.
Molecular bodyguards against Parkinson's disease
Chaperone proteins in human cells dynamically interact with the protein α-Synuclein, which is strongly associated with Parkinson's disease. A disturbed relationship to these 'bodyguards' leads to cell damage and the formation of Lewy bodies typical for Parkinson's disease. The findings by researchers from the University of Basel's Biozentrum have been published in Nature.
NASA finds wind shear battering tropical cyclone 07A
NASA's Aqua satellite found that wind shear was tearing at Tropical Storm 07A in the Arabian Sea.
NASA's OSIRIS-REx in the midst of site selection
After a lengthy and challenging process, the team is finally ready to down-select from the four candidate sites to a primary and backup site.
NASA's Parker Solar Probe sheds new light on the sun
Since its 2018 launch, NASA's Parker Solar Probe (record-holder for closest-ever spacecraft to the Sun) has finished three of 24 planned passes through never-before-explored parts of the Sun's atmosphere. On Dec. 4, four new papers describe what scientists have learned from its unprecedented exploration, and what they look forward to learning next.
New 'hyper glue' formula developed by UBCO and UVic researchers
With many of the products we use every day held together by adhesives, researchers from UBC's Okanagan campus and the University of Victoria hope to make everything from protective clothing to medical implants and residential plumbing stronger and more corrosion resistant thanks to a newly-developed 'hyper glue' formula.
New cell models for ocular drug discovery
Researchers at the University of Eastern Finland have developed two new cell models that can open up new avenues for ocular drug discovery. The new cell models are continuously growing retinal pigment epithelial cells, which have many benefits over the models currently used by researchers and pharmaceutical companies.
New diagnostic techniques and drug may slow and even reverse cognitive decline from aging
When given the new drug to reduce inflammation, senile mice had fewer signs of dysfunctional brain electrical activity and were better able to learn new tasks, becoming almost cognitively adept as mice half their age. Other findings indicate two practical pathways -- measuring the leakiness of the blood-brain barrier via MRI and abnormal electrical brain activity via EEG -- that can be used to screen people for a leaky BBB.
New study provides insight into chronic kidney disease
Researchers have further analyzed a known signaling pathway they believe brings them one step closer to understanding the complex physiology of patients with chronic kidney disease (CKD), which might provide a path to new treatment options.
New technology CF LINK for protein bioconjugation and structural proteomics
CF Plus Chemicals, a spin-off of ETH Zurich, IOCB Prague, and IMIC have developed a new technology called CF LINK for site-selective bioconjugation of proteins and also their structural characterization. The recently published, patent-pending technology allows to selectively prepare protein conjugates via their tryptophan residues and perform posttranslational modification of aromatic amino acids. Furthermore, it can also be used as a tool for the mapping of protein surfaces and studies of protein-protein interactions.
New treatment to tackle drug-resistant strains of TB could now be possible
New drugs to treat strains of TB which have become resistant to treatment are now a possibility following a groundbreaking discovery from the University of Surrey.
NOTCH1 signaling in oral squamous cell carcinoma via a TEL2/SERPINE1 axis
In this study, the research team investigated NOTCH1 mutations in keratinocyte lines derived from OSCC biopsies that had been subjected to whole exome sequencing.
Once-a-month oral contraceptive could improve patient adherence
Researchers have created a new ingestible drug delivery platform that expands in the stomach and could safely deliver a contraceptive over one month when tested in pigs.
Online therapy helped cardiovascular disease patients with depression
Researchers at Linköping University have developed a treatment for depression among people with cardiovascular disease. The results, recently published in JMIR Mental Health, show that cardiovascular disease patients who underwent internet-based therapy for their depression became less depressed and gained a better quality of life.
Parker Solar Probe traces solar wind to its source on sun's surface: coronal holes
New data from the Parker Solar Probe, which got closer to the sun than any other spacecraft, allowed physicists to map the source of a major component of the solar wind that continually peppers Earth. The slow solar wind seems to emerge from coronal holes along the sun's equator. Data also reveal strange magnetic field reversals that could be accelerating solar wind particles, and an unexpectedly dense shroud of comet dust around the sun.
Patients' perspectives of clinical consultations related to weight
A recent review in Clinical Obesity assessed patients' reactions to consultations with physicians in which excess weight could have been or was discussed.
Permanent hair dye and straighteners may increase breast cancer risk
Scientists at the National Institutes of Health found that women who use permanent hair dye and chemical hair straighteners have a higher risk of developing breast cancer than women who don't use these products. The study published online Dec. 4 in the International Journal of Cancer and suggests that breast cancer risk increased with more frequent use of these chemical hair products.
Police killings of unarmed black Americans may have health impacts for nearby unborn black infants
Pregnant black women give birth to infants with smaller birth weights and shorter gestational ages if they live near the site of incidents in which unarmed blacks are killed by police during their first or second trimester, according to a new study.
Probiotic may help treat colic in infants
Probiotics -- or 'good bacteria' -- have been used to treat infant colic with varying success. In a new trial published in the journal Alimentary Pharmacology & Therapeutics, investigators have shown that drops containing a particular probiotic strain (Bifidobacterium animalis subsp. lactis BB-12) reduced the duration of daily crying by more than 50% in 80% of the 40 infants who received the probiotic once daily for 28 days, with beneficial effects on sleep duration and on stool frequency and consistency.
Properties of graphene change due to water and oxygen
Professor Sunmin Ryu and his research team investigated the oxidation-reduction principle of two-dimensional materials by interfacial diffusion.
Record-size sex chromosome found in two bird species
Researchers in Sweden and the UK have discovered the largest known avian sex chromosome. The giant chromosome was created when four chromosomes fused together into one, and has been found in two species of lark.
