Breakthrough in photonic chip research paves way for ultrafast information sharing
- ScienceDaily
- 11/8/4 20:16
Researchers have discovered a way to prevent light signals on a silicon chip from reflecting backwards and interfering with its operation. Otherwise, the light beams would interfere with lasers and other photonic components on the chip and make the chip unstable. The breakthrough marks a significant achievement in the development of integrated photonic chips that could replace electronic chips as...

Dark, narrow features running down slopes in the warmer regions of Mars point to the possibility of salty water as the causing agent. Never observed before and strongly associated with the warmer seasons on Mars, the features show growth, suggesting they may form near the surface today in rare times and places.Never observed before and strongly associated with the warmer seasons on Mars, the...
Species share perceptual capabilities that affect how communication evolves, research finds
- ScienceDaily
- 11/8/4 20:16
New research reveals that two entirely different species show similar perception of auditory cues that drive basic biological functions; that these perceptions may be universally shared among animals; and that such perception may also limit the evolution of communication...

B-cell discovery suggests why women suffer more autoimmune disease
- ScienceDaily
- 11/8/4 19:36
Researchers report the discovery of a new type of cell that makes autoantibodies, which attack the body's own tissues. It is more common in elderly female mice and humans with autoimmune disease. An application for a patent has been made for a method to treat autoimmune disease by depleting these...

A new study statistically demonstrates the positive health consequences of an emotionally supportive workplace.
Poorly controlled asthma costly, study finds
- ScienceDaily
- 11/8/4 19:36
Poorly controlled asthma more than doubles health-care costs associated with the disease and threatens educational achievement through a dramatic increase in school absence, according to researchers. It highlights the toll that poorly controlled asthma takes on children. It also points to an...
Studies shed light on hand hygiene knowledge and infection risk in hospitals and elementary schools
- ScienceDaily
- 11/8/4 19:34
Increased hand hygiene knowledge positively correlates with a decreased risk of transmitting infection among both healthcare workers and elementary school children, according to two studies.
Surprising condition occurs in lungs after an invasion of mold, study shows

Researchers have found a surprising condition that occurs in the lungs after an invasion of a common, but potentially dangerous, mold.
Assumptions, not data, dictate opinions about predictive genetic testing in youth
- ScienceDaily
- 11/8/4 18:46
Predictive genetic testing may be able to identify children's risk for developing common, treatable, and possibly preventable disorders. Despite this, critics of predictive genetic testing say test results may be psychologically harmful to children. However, these claims are rooted in assumption, not evidence, says one...

Whether it is a purple potato to fit a niche market or finding varieties resistant or at least tolerant to psyllid infestations, one researcher has a potato plant aimed at meeting a grower's need.
Researchers find way to help donor adult blood stem cells overcome transplant rejection
- ScienceDaily
- 11/8/4 18:46
Findings may suggest new strategies for successful donor adult stem cell transplants in patients with blood cancers such as leukemia, lymphoma and myeloma.
Use of a retroflexion technique during colonoscopy in the right side of the colon improves polyp detection
- ScienceDaily
- 11/8/4 18:46
The use of a retroflexion technique in the right side of the colon during colonoscopy is safe and results in the detection of additional adenomatous (precancerous) polyps in approximately four percent of patients, new research suggests. This result is comparable to that expected from a second colonoscopy in the forward...
Hormone reduces risk of heart failure from chemotherapy, study suggests
- ScienceDaily
- 11/8/4 18:39
A new study utilizing a heart failure model is providing insight into one way to coax the cardiac stem cells into repairing the damaged heart. The research finds that low doses of erythropoietin (EPO), a hormone best known for controlling the production of red blood cells, might reduce the risk of heart failure associated with some anticancer...
