Brain drainage? Like the Brain Benefit: How Skilled Immigrants Increase Global Prosperity
Credit: CC0 Public Domain As public debate intensifies around immigration, new research from the University of California School of Global Policy and Strategic is challenging traditional wisdom about “brain drain.” This is the idea that when skilled workers migrate from developing countries, their housekeeping squads suffer. The paper, published in Science, reveals that advanced immigration from developing countries can in…

Light signature algorithms provide accurate insights into viral proteins, brain disease markers and semiconductors
Ziyang Wang and Shengxi Huang. Credit: Jeff Fitlow/Rice University Researchers at Rice University have developed new machine learning (ML) algorithms that are excellent at interpreting “light signatures” (optical spectra) of molecules, materials and disease biomarkers, potentially enabling faster, more accurate medical diagnosis and sample analysis. “The first author of the study published in ACS Nano,” said Ziyang Wang, a doctoral…

Cholesterol-modified oligonucleotides promise to treat brain diseases
This study revealed that by binding to lipoproteins, cholesterol-binding heteroduplex oligonucleotides (chol-hdos) can stay in the bloodstream for longer and reach brain tissue much more effectively than the counterpart of antisense oligonucleotides (ASOs). These findings pave the way for the development of brain-targeted gene regulatory drugs. Credit: Tokyo University of Science, Nishikawa, Japan Taking medications past the blood-brain barrier has…

“Birdsong Chat” may shed light on how language is wired in the human brain
Credit: Images generated by AI Just as ChatGpt and other generative language models create grammatically correct sentences to train human texts, a new modeling method by researchers of the Pennsylvania State Train is to create accurate bird angs. A new modelling method for bird recording. The results could improve understanding of the structure of birds and their underlying neurobiology, which…

Nanoparticles restore Parkinson’s disease neurons with wireless brain stimulation
A practical model demonstrating wireless DBS mediated by ATB NPs to reverse PD. Credit: Science Advances (2025). DOI: 10.1126/sciadv.ado4927 Parkinson’s disease (PD) is the second most common neurodegenerative disease and is primarily characterized by motor dysfunction. Its pathological hallmark is the abnormal aggregation of α-synuclein (α-syn) into insoluble fibrils and Lewy bodies, which causes degeneration and death of dopaminergic neurons…

Surprising discovery sheds light on the cause of Huntington’s disease, a deadly brain disorder
This micrograph provided by the Harvard Brain Tissue Resource Center at McLean Hospital in January 2024 shows cells within the caudate nucleus structure of the brain of a patient with Huntington’s disease. Credit: Harvard Brain Tissue Resource Center at McLean Hospital/NIH NeuroBioBank (via AP) Scientists are unraveling the mysteries that trigger Huntington’s disease. Huntington’s disease is a devastating and fatal…

Brain cells mature faster in space, but stay healthy: ISS study
Credit: Stem Cell Translational Medicine (2024). DOI: 10.1093/stcltm/szae070 Microgravity is known to alter muscles, bones, the immune system, and cognition, but little is known about its specific effects on the brain. To understand how brain cells respond to microgravity, Scripps Research Institute scientists teamed up with the New York Stem Cell Foundation to send small clumps of stem cell-derived brain…
