Infections in hospitalised individuals may arise from their own germs: Stu
Updated : 3 years, 1 month ago IST
Hospitals have strong cleanliness and sanitation measures in place to protect patients from microorganisms that rarely affect healthy people but can be deadly to vulnerable patients who are already hospitalised with serious illnesses.

Ethical ancient DNA research must involve descendant communities
Updated : 3 years, 1 month ago IST
The analysis of ancient DNA allows scientists to trace human evolution and make important discoveries about modern populations. The data revealed by ancient DNA sampling can be valuable, but the human remains that carry this ancient DNA are often those of the ancestors of modern Indigenous g

Overactive cell metabolism linked to biological ageing: Research
Updated : 3 years, 1 month ago IST
Why do cells, and by extension humans, age? The answer may have a lot to do with mitochondria, the organelles that supply cells with energy. Though that idea is not new, direct evidence in human cells had been lacking.

Enzyme 'atlas' helps researchers decipher cellular pathways
Updated : 3 years, 1 month ago IST
A new atlas maps more than 300 protein kinases found in human cells and identifies which types of protein substrates they target. The atlas could help scientists understand what happens when cells become cancerous or are treated with specific drugs.

Study: Hospitalised patients' infections may develop from their own bacter
Updated : 3 years, 2 months ago IST
Hospitals have strict hygiene and sanitation protocols to protect patients from bacteria that rarely sicken healthy people but can be deadly for vulnerable patients already hospitalized with serious illnesses. Nearly 100,000 people die every year in U.S. hospitals of infections they develop

Physicists model cell migration to learn how cancer cells navigate tissue
Updated : 3 years, 2 months ago IST
This migration mode is one of the ways cancer cells navigate tissue during metastasis. In a new study researchers have explored mesenchymal migration through cell simulations and mathematical modeling. Their aim: to learn more about how cancer cells size up surrounding tissue for stiffness a

Cat locomotion could unlock better human spinal cord injury treatment: Res
Updated : 3 years, 2 months ago IST
Cats always land on their feet, but what makes them so agile? Their unique sense of balance has more in common with humans than it may appear. Researchers at the Georgia Institute of Technology are studying cat locomotion to better understand how the spinal cord works to help humans with par

Researchers discover toxic process involving 'jumping genes'
Updated : 3 years, 2 months ago IST
Scientists from The University of Texas Health Science Center at San Antonio (UT Health San Antonio) today reported that an inflammatory trigger like one present during viral infections is elevated in Alzheimer's disease and progressive supranuclear palsy, a rare brain disorder.

Lyme disease heightens risk of mental disorders, suicidality: Study
Updated : 3 years, 2 months ago IST
In a new study, U.S. and Danish researchers report that patients hospitalized with Lyme disease had a 28 per cent higher rate of mental disorders and were twice as likely to have attempted suicide post-infection, compared to individuals without the diagnosis.

Cardiac progenitor cells generate healthy tissue after heart attack
Updated : 3 years, 2 months ago IST
Following a heart attack, the human body is incapable of repairing lost tissue due to the heart's inability to generate new muscle. However, treatment with heart progenitor cells could result in the formation of functional heart cells at injured sites. This new therapeutic approach is introd
