WHO raises alarm on disease in flood-hit areas of Pakistan

Displaced families, who fled their flood-hit homes, jostle to get relief aid distributed by soldiers of Pakistan rangers, in Dera Allahyar, in Jaffarabad, a district of southwestern Balochistan province, Saturday, Sept. 17, 2022. The floods affected over 33 million people and displaced over half a million people who are still living in tents and make-shift … Read more

Liquid-interface assisted SERS could see earlier detection of Alzheimer’s disease

Figure 1. Schematic of laser fabrication system for microfluidic SERS chips. Credit: Compuscript Ltd A new publication from Opto-Electronic Advances discusses label-free trace detection of bio-molecules by liquid-interface assisted surface-enhanced Raman scattering using a microfluidic chip. Surface-enhanced Raman scattering (SERS) has attracted attention in biotechnology. It is due to its high sensitivity to localized surface … Read more

Researchers identify a potential path against inherited neurological disease

Researchers at the Icahn School of Medicine at Mount Sinai and NCATS identified compounds that reversed the effects of several neurodegenerative diseases called lysosomal storage disorders (LSDs) in patient cells and mice. LSDs are characterized by genetic defects that prevent the cell’s lysosomes from breaking down and recycling fats, sugars and proteins, which can accumulate … Read more

Researchers find spaceflight may be associated with DNA mutations, increased risk of heart disease and cancer

a) We identified somatic mutations in known clonal hematopoiesis of indeterminate potential (CHIP) driver genes using peripheral blood mononuclear cells isolated from 14 astronauts who flew short space Shuttle missions lasting a median of 12 days between 1998–2001. Created with b) Number of somatic nonsynonymous single nucleotide variants (SNVs) in CHIP-driver genes harbored per … Read more

Slugs, snails are not alone in causing rat lungworm disease in humans

New clues to how plants retain healthy genomes, avoid mitochondrial disease

MSH1 repairs organelle DNA. The MSH1 protein slides along a DNA strand until it detects mutations. Then MSH1 cuts both strands of DNA. The DNA repair machinery in the cell uses homologous DNA (DNA of the same sequence) as a template to fix the mutation. B) MSH1 increases sorting of organelle DNA. A population of … Read more

Famine and disease drove the evolution of lactose tolerance in Europe

Credit: Pixabay/CC0 Public Domain Prehistoric people in Europe were consuming milk thousands of years before humans evolved the genetic trait allowing us to digest the milk sugar lactose as adults, finds a new study. The research, published in Naturemapped pre-historic patterns of milk use over the last 9,000 years, offering new insights into milk consumption … Read more
