New, old science combine to make faster medical test Posted: 19 Jan 2017 04:45 PM PST Magnetic nanoparticles are coated with an antibody, then aligned in formation within a magnetic field and tallied under laser optics. The result could lead to speedy diagnoses for infectious diseases.

Study discusses model for understanding nutrition and brain development Posted: 19 Jan 2017 04:45 PM PST For nearly a decade, researchers have studied the piglet as a translational model to understand which aspects of early brain development are affected by nutrition interventions. In a recent review article, investigators provide background for the work they do with nutrition and neurodevelopment using the piglet as a model.

Team uncovers cellular responses to bird flu vaccine Posted: 19 Jan 2017 04:45 PM PST New research eavesdrops on gene expression in human immune system cells before and after vaccination against bird flu, exposing cellular responses associated with a vaccine constituent called AS03, short for adjuvant system 03. Using massive computation, the investigators pursue a systems biology approach, providing a new wealth of detail about vaccine responses and data for the generation of new hypotheses.

How bacteria exploit a chink in the body's armor Posted: 19 Jan 2017 04:45 PM PST Scientists have discovered how a unique bacterial enzyme can blunt the body's key weapons in its fight against infection.

Type 1 diabetes linked to gut inflammation, bacteria changes Posted: 19 Jan 2017 01:34 PM PST People with Type 1 diabetes exhibit inflammation in the digestive tract and gut bacteria, a pattern that differs from individuals who do not have diabetes or those who have celiac disease, according to a new study.

Breast cancer prognosis of African-American patients may improve with administration of chemotherapy before surgery, study finds Posted: 19 Jan 2017 01:33 PM PST Administering chemotherapy to African-American breast cancer patients prior to surgery could improve their prognosis and survival rates from the disease, according to a new study.

Scientists initiate first ethical guidelines for organs cultivated in vitro Posted: 19 Jan 2017 01:30 PM PST Scientists have created an ethical guideline for research into human organ models.

Surgical site infections are the most common and costly of hospital infections Posted: 19 Jan 2017 01:15 PM PST Researchers updated guidelines for the prevention, detection and management of surgical site infections, which affect as many as 300,000 patients per year in the United States.

New findings on how plants manage immune response Posted: 19 Jan 2017 01:15 PM PST New research has uncovered a previously unknown means by which plants are able to regulate how their immune systems respond to pathogens.

Seeking structure with metagenome sequences Posted: 19 Jan 2017 01:15 PM PST Scientists now report that structural models have been generated for 12 percent of the protein families that had previously had no structural information available.

Brief interventions help online learners persist with coursework Posted: 19 Jan 2017 11:36 AM PST New research shows people in underdeveloped parts of the world are not as likely to complete massive open online courses, or MOOCs. But small psychological activities could help motivate them, closing the global achievement gap.

Sea-surface temps during last interglacial period like modern temps Posted: 19 Jan 2017 11:33 AM PST Sea-surface temperatures during the last interglaciation period were like those of today, a new study reports. The trend is worrisome, as sea levels during the last interglacial period were between six and nine meters above their present height.

Jumbled chromosomes may dampen the immune response to tumors Posted: 19 Jan 2017 11:33 AM PST How well a tumor responds to immunotherapy may depend in part on whether its chromosomes are intact or in a state of disarray, a new study reports. The finding could help doctors better pinpoint which cancer patients would benefit from immunotherapy.

Official abortion rate declined in Texas after law restricted access to clinics Posted: 19 Jan 2017 10:46 AM PST In Texas, increases in travel distance to the nearest abortion clinic caused by clinic closures were closely associated with decreases in the official number of abortions, report investigators.

Why the lights don't dim when we blink Posted: 19 Jan 2017 10:45 AM PST Every few seconds, our eyelids automatically shutter and our eyeballs roll back in their sockets. So why doesn't blinking plunge us into intermittent darkness and light? New research shows that the brain works extra hard to stabilize our vision despite our fluttering eyes.

As cells age, the fat content within them shifts Posted: 19 Jan 2017 10:45 AM PST As cells age and stop dividing, their fat content changes, along with the way they produce and break down fat and other molecules classified as lipids. By providing broad insights into the connection between lipids and cellular aging, the findings open the door for additional research that could support the development of lipid-based approaches to preventing cell death or hastening it in cancerous tumors.

Plan A is to get patients to stick to their blood pressure pills Posted: 19 Jan 2017 07:02 AM PST There is value in starting off patients with high blood pressure on an all-in-one pill. Researchers found more value in fixed-dose combination pills that contain more than one type of medication, rather than separate pills for each drug.

Blood test can predict life or death outcome for patients with Ebola virus disease Posted: 19 Jan 2017 05:46 AM PST Scientists have identified a 'molecular barcode' in the blood of patients with Ebola that can predict whether they are likely to survive or die from the viral infection. Scientists have used blood samples taken from infected and recovering patients during the 2013-2016 West Africa outbreak to identify gene products that act as strong predictors of patient outcome.
