Penn-led researchers gain better understanding of how T cells support long-lived plasma cells

If you've ever wondered how a vaccine given decades ago can still protect against infection, you have your plasma cells to thank. Plasma cells are long-lived B cells that reside in the bone marrow and churn out antibodies against previously encountered vaccines or pathogens.

New fluid makes ultrasound images easier to interpret during brain surgery

The fluid, which resembles brain tissue, makes ultrasound images easier to interpret during an operation. This will make it easier for surgeons to remove brain tumours more accurately.

New portable device may hold key to accurately detecting Zika virus

About the size of a tablet, a portable device that could be used in a host of environments like a busy airport or even a remote location in South America, may hold the key to detecting the dreaded Zika virus accurately, rapidly and inexpensively using just a saliva sample.

Successful insomnia treatment may not require complicated neurofeedback, study shows

A new study published in Brain indicates that successful treatment for insomnia may not actually require complicated neurofeedback (direct training of brain functions). Rather, it appears patients who simply believe they're getting neurofeedback training appear to get the same benefits.

NIH launches new study to test experimental vaccine that targets mosquito-transmitted diseases

The National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, has launched a Phase 1 clinical trial to test an investigational vaccine intended to provide broad protection against a range of mosquito-transmitted diseases, such as Zika, malaria, West Nile fever and dengue fever, and to hinder the ability of mosquitoes to transmit such infections.

Higher EPA and DHA omega-3 levels linked to lower risk of death in postmenopausal women

A study published in the Journal of Clinical Lipidology found that higher levels of EPA and DHA omega-3 polyunsaturated fatty acids in red blood cells were associated with a lower risk of all-cause mortality in postmenopausal women.

Crowdsourcing effort helps develop mathematical model to forecast scent of molecule

You can anticipate a color before you see it, based solely on the length of light waves. Music can be interpreted from notes on a page without being heard. Not so with odor. The only way to tell if something will smell like roses or turpentine, sea breeze or gasoline, is to sniff it.

Cancer cells adapt nerve cell mechanisms to fuel aggressive tumor growth and spread

How we think and fall in love are controlled by lightning-fast electrochemical signals across synapses, the dynamic spaces between nerve cells. Until now, nobody knew that cancer cells can repurpose tools of neuronal communication to fuel aggressive tumor growth and spread.
