Proposed cuts to US Malaria Initiative could mean millions more malaria cases

12 hours 22 min ago
Cutting the budget of the President's Malaria Initiative (PMI) by 44 percent, as the US Congress has proposed, would lead to an estimated 67 million additional cases of malaria over the next four years, according to a mathematical model.

Second HIV test helps prevent incorrect HIV diagnosis in infants

12 hours 22 min ago
Confirmatory HIV testing can substantially reduce the number of infants in South Africa who may be falsely diagnosed as HIV-infected and started on unneeded treatment, according to a new study.

Specific tumor environment found that triggers cells to metastasize

12 hours 22 min ago
The environment surrounding a tumor can trigger metastatic behavior in cancer cells, a team of bioengineers and bioinformaticians has discovered. Specifically, when tumor cells are confined in a dense environment, the researchers found that they turn on a specific set of genes and begin to form structures that resemble blood vessels.

A novel method, developed by an economist has been created to evaluate a worker's skillset and determine its impact on wages.

How disposable diapers can improve measurements of tumor growth

Tue, 11/21/2017 - 23:55
In pursuit of a better imaging phantom for improved tumor measurements, scientists hit upon an effective but unconventional solution: injecting water into disposable diapers.

Turtles and technology advance understanding of lung abnormality

Tue, 11/21/2017 - 23:55
A study of an unusual snapping turtle with one lung found shared characteristics with humans born with one lung who survive beyond infancy. New digital 3-D anatomical models made the detailed research possible.

New study points the way to therapy for rare cancer that targets the young

Tue, 11/21/2017 - 23:55
Scientists have engineered a mouse model to study a rare and often-fatal form of liver cancer. They've used it to clarify what drives these tumors at the molecular level, and discover new drug concepts.

Maintaining sufficient vitamin D levels may help to prevent rheumatoid arthritis

Tue, 11/21/2017 - 23:03
Maintaining sufficient vitamin D levels may help to prevent the onset of inflammatory diseases like rheumatoid arthritis, research has discovered.

Function of an enigmatic synaptic protein defined

Tue, 11/21/2017 - 22:45
Communication is often mired in contradiction -- also in the brain. Neuroscientists have now resolved one such contradiction. The role of Synaptotagmin 7 has been controversial: There was a contradiction between the function it seemed to have, and the characteristics of signal transmission observed. Now, for the first time, scientists defined its functional contribution at an inhibitory GABAergic synapse: it ensures the efficiency of high-frequency inhibitory synaptic transmission.

Good cells gone bad: Scientists discover PINK-SNO[W]

Tue, 11/21/2017 - 22:45
A new study is the first to show precisely how a process in nerve cells, called the S-nitrosylation (SNO) reaction, may contribute to Parkinson's disease.

New findings to help HIV scientists establish 'template' for potent antibodies

Tue, 11/21/2017 - 22:45
New data further illuminate how some human beings generate powerful, HIV-blocking antibodies. These results offer important insight into a potential AIDS vaccine design.

Virtual reality allows you to look inside your body and could help improve drug delivery

Tue, 11/21/2017 - 22:44
Renderings of 3-D cells in the body are traditionally displayed using 2-D media, such as on a computer screen or paper; however, the advent of Virtual Reality (VR) headsets means it is now possible to visualize and interact with scientific data in a 3-D virtual world.

What does it mean for the husband when his wife keeps her own surname?

Tue, 11/21/2017 - 22:44
When a woman chooses not to take her husband's surname after marriage, people perceive her husband as being higher in traits related to femininity and lower in traits related to masculinity. He is also perceived as having less power in the relationship.

The three-dimensional folding of DNA provides important epigenetic mechanisms in the formation of cardiac muscle cells.

New simple test could help cystic fibrosis patients find best treatment

Tue, 11/21/2017 - 22:44
While new CF drugs are life-changing for some patients, they don't work for everyone. Now, researchers present a simple test that aims to predict which treatment is most likely to work for each patient, an approach known as personalized or precision medicine.

Children with Alagille Syndrome have malformed bile ducts

Tue, 11/21/2017 - 22:40
Serious liver and heart problems can affect children with Alagille Syndrome early in life. While there is as yet no cure, researchers have discovered that the liver disease part of the syndrome is caused by specific malformations of the bile ducts. The results were discovered with the aid of a new mouse model that can now be used to develop and test new therapies.

Tue, 11/21/2017 - 20:42
Five distinct subgroups of eczema have been identified by researchers, a finding that helps explain how the condition can affect people at different stages of their lives.

Simple electrocardiogram can determine whether a patient has major depression or bipolar disorder, study finds

Tue, 11/21/2017 - 20:24
A simple 15-minute electrocardiogram could help a physician determine whether a patient has major depression or bipolar disorder, a groundbreaking new study reports.

Sensors could identify biomarkers, improve early-stage detection, treatment of diseases

Tue, 11/21/2017 - 20:22
Researchers have found a method of identifying biological markers in small amounts of blood that they believe could be used to detect a myriad of diseases, infections and different medical conditions at early stages. The researchers have created microelectromechanical resonators, or small vibrating sensors, that can detect these biomarkers using just a drop or two of blood.

Disordered eating among young adults found to have long-term negative health effects

Tue, 11/21/2017 - 20:22
According to a recent study, disordered eating among young adults has long-term effects on their health. Disordered eating among 24-year-old women and men was an indicator of higher body weight, larger waist circumference and lower psychological well-being as well as a lower self-evaluation of general health both at age 24 and ten years later.
