Corporate codes of ethics can have reverse effects and mask anomalies or social evils in operations outsourced to low-wage countries, suggests a new study.
Today, a stroke usually leads to permanent disability – but in the future, the stroke-injured brain could be reparable by replacing dead cells with new, healthy neurons, using transplantation. Researchers have taken a step in that direction by showing that some neurons transplanted into the brains of stroke-injured rats were incorporated and responded correctly when the rat’s muzzle and paws were touched.
Using visualization technology, visitors to the British Museum can reveal the murder of the mummified Geberlein Man, 5,500 years ago.
Liver metastases are formed from cancer cells that have originated in other organs and migrated to the liver via the bloodstream. Colorectal cancer (cancer of the colon/rectum) can be successfully treated by surgical resection of the metastases in combination with chemotherapy. Now a research team has identified a new biomarker that allows better prediction of survival following surgical removal of the metastases, as well as a change in the clinical significance of the biomarker following chemotherapy.
Discrepancy between the theoretical, experimental results of a system of biological interest is resolved
A piece of research has resolved the tautomeric equilibrium of a model system of great biological interest. The work was made possible by setting up a piece of equipment that they themselves developed to characterize sets of molecules in a very accurate way. The research has thus put an end to the controversy that existed between the prior experiments and theoretical calculations that yielded contradictory and inconclusive results.
A study shows new mechanisms behind Parkinson's disease, which can be key mechanisms for future treatment. More than 10 million people worldwide have Parkinson´s disease.
Germline cells are the only cells that develop into eggs or sperm, while somatic cells develop into the body. Progenitors of the germline, known as primordial germ cells (PGCs), differentiate into eggs or sperm after embryonic development. The expression of a select group of genes occurs in the PGCs of a number of different animal groups, indicating a possible conserved mechanism of germline gene activation. Until now, it has been unclear if Ovo was needed for normal germline development of the fruit fly, or whether the related mouse protein played a similar role in mouse embryos.
Scientists have clarified that toroidal magnets can also look for axions, one of the particle candidates for the mysterious dark matter.
Scientists have presented a prototype for a 3D bioprinter that can create totally functional human skin. This skin is adequate for transplanting to patients or for use in research or the testing of cosmetic, chemical, and pharmaceutical products.
In a recent study of adults with early memory loss, scientists found that practice of a simple meditation or music listening program may have multiple benefits for older adults with preclinical memory loss.
From climate skeptics to anti-vaxxers, psychologists are studying what motivates and drives our decisions to pay attention to some facts while ignoring others.
Service members, including both active and recently separated, have been called upon to fight overseas and to assist during natural disasters at home. They can face unique challenges when they return in both the workplace and at home. New research, focused on these service member couples in Oregon, confirms supportive, responsive partners provide a buffer to loneliness and sleep deficits among military couples.
A new Processing Speed Training Game (PSTG) has been developed for a Tablet PC, which they say can significantly improve processing speed and inhibition among healthy older adults, while also reducing their depressive moods when played regularly.
A new theoretical model reveals how droplets grow around tiny particles on a surface.
Experts from CDC are working with the Illinois Department of Health and the Wisconsin Department of Health Services to investigate cases of Seoul virus infections among eight people who worked at several rat-breeding facilities in the two states. Seoul virus is not commonly found in the United States, though there have been several reported outbreaks in wild rats. This is the first known outbreak associated with pet rats in the United States.
The first molecular study of an organism able to survive intracellular freezing (freezing within its cells) is published in a new paper that represents a milestone in scientists’ understanding of an extraordinary adaptation.
Using a novel approach for imaging the movement of immune cells in living animals, researchers have identified what appear to be the initial steps leading to joint inflammation in a model of inflammatory arthritis.
Scientists report findings of how triple negative breast cancer cells are able to bypass treatment with trametinib, a U.S. Food and Drug Administration-approved drug that belongs to a class of commonly used anti-cancer drugs called kinase inhibitors. The researchers also reported findings from laboratory models of breast cancer testing a potential treatment approach that could prevent the onset of resistance.
A new high-tech medical device to make brain surgery safer has now been developed.
A new technique will help biologists tinker with genes, whether the goal is to turn cells into tiny factories churning out medicines, modify crops to grow with limited water or study the effects of a gene on human health. The technique allows scientists to precisely regulate how much protein is produced from a particular gene. The process is simple yet innovative and, so far, works in everything from bacteria to plants to human cells.
