Saying one thing while feeling another is part of being human, but bottling up emotions can have serious psychological consequences like anxiety or panic attacks. To help health care providers tell the difference, a team led by scientists at Penn State has created a stretchable, rechargeable sticker that can detect real emotions — by measuring things like skin temperature and heart rate — even when users put on a brave face.  The researchers recently unveiled the wearable patch that can simultaneously and accurately track multiple emotional signals in a study published in the journal Nano Letters.

High-intensity electrical pulses have been medically used to destroy tumors while sparing healthy tissue. But lower-intensity pulses may have a different effect — they reshape the battlefield, making tumors more vulnerable to the body’s own defenses.

Researchers at Virginia Tech have discovered that these lower-intensity pulses alter the tumor’s environment, increasing blood vessel density within a day of treatment and boosting lymphatic vessel growth by day three. These changes may help guide immune cells to the tumor, potentially improving the body's natural ability to fight cancer.  Source: Virginia Tech News

Scientists have transformed RNA, a biological molecule present in all living cells, into a biosensor that can detect tiny chemicals relevant to human health.

Research by Rutgers University-New Brunswick scientists centers on RNA, a nucleic acid that plays a crucial role in most cellular processes. Their work is expected to have applications in the surveillance of environmental chemicals and, ultimately, the diagnosis of critical diseases including neurological and cardiovascular diseases and cancer.  Source: Rutgers Today

Investigators from Mass General Brigham and Beth Israel Deaconess Medical Center have developed STITCHR, a new gene editing tool that can insert therapeutic genes into specific locations without causing unwanted mutations. The system can be formulated completely as RNA, dramatically simplifying delivery logistics compared to traditional systems that use both RNA and DNA.  Source: Massachusetts General Brigham

Northwestern University researchers have developed the first wearable device for measuring gases emitted from and absorbed by the skin.

By analyzing these gases, the device offers an entirely new way to assess skin health, including monitoring wounds, detecting skin infections, tracking hydration levels, quantifying exposure to harmful environmental chemicals and more. Source: Northwestern Now

A new artificial intelligence (AI) tool that can help interpret and assess how well treatments are working for patients with multiple sclerosis (MS) has been developed by University College London researchers. Source: University College London News

Blood clots are associated with life-threatening conditions such as sepsis, sickle cell disease, heart attack and stroke. However, new research from Emory University may revolutionize how clinicians understand and treat these harmful blood clots, or thrombi, a byproduct of a condition called thromboinflammation. 

In a groundbreaking study published in Nature, researchers have discovered the potential to provide life-saving medications to patients with blood clots at the right time, with the right dose, in novel combinations based on a new model.  Source: Emory University News Center

While medical centers use ultrasound daily, so far this technology has not been capable of observing body tissues at the scale of cells. Physicists at several universities including CalTech have now developed a microscopy technique based on ultrasound to reveal capillaries and cells across living organs -- something that wasn't possible before.

Drug-carrying DNA snippets called aptamers can deliver a one-two punch to leukemia by precisely targeting the elusive cancer stem cells that seed cancer relapses, researchers at the University of Illinois Urbana-Champaign report.

The aptamers — short single-strand snippets of DNA that can target molecules like larger antibodies do — not only deliver cancer-fighting drugs, but also are themselves toxic to the cancer stem cells, the researchers said.
