Immunotherapy boosts a person’s own immune system to identify and fight cancer cells that normally evade its defenses.

However, like traditional cancer treatments, immunotherapy may cause or exacerbate cognitive decline, especially in older adults. Because this treatment is much newer than chemotherapy or radiation, these potential side effects have not yet been widely studied.

Gee Su Yang, assistant professor at the UConn School of Nursing, has received a $60,000 CRISP (Clinical Research Innovation Seed Program) Award from the Office of the Vice President for Research to conduct a pilot study of how immunotherapy impacts cognitive function in older cancer patients.

Empa researchers are working on artificial muscles that can keep up with the real thing. They have now developed a method of producing the soft and elastic, yet powerful structures using 3D printing. One day, these could be used in medicine or robotics – and anywhere else where things need to move at the touch of a button.


A team of researchers from Empa’s Laboratory for Functional Polymers is working on actuators made of soft materials. Now, for the first time, they have developed a method for producing such complex components using a 3D printer. The so-called dielectric elastic actuators (DEA) consist of two different silicone-based materials: a conductive electrode material and a non-conductive dielectric. These materials interlock in layers. “It’s a bit like interlacing your fingers,” explains Empa researcher Patrick Danner. If an electrical voltage is applied to the electrodes, the actuator contracts like a muscle. When the voltage is switched off, it relaxes to its original position.

3D printing such a structure is not trivial, Danner knows. Despite their very different electrical properties, the two soft materials should behave very similarly during the printing process. They should not mix but must still hold together in the finished actuator. The printed “muscles” must be as soft as possible so that an electrical stimulus can cause the required deformation. Added to this are the requirements that all 3D printable materials must fulfill: They must liquefy under pressure so that they can be extruded out of the printer nozzle. Immediately thereafter, however, they should be viscous enough to retain the printed shape. “These properties are often in direct contradiction,” says Danner. “If you optimize one of them, three others change … usually for the worse.”

Did you know that up to 20% of people with lung cancer have never smoked?

Sherlock-Lung is a comprehensive study that uses genomic approaches to trace the causes of lung cancer among people who have never smoked.


Sherlock Lung is a genomic epidemiologic study of lung cancer in never smokers conducted by researchers in DCEG.

Histone proteins provide essential structural support for DNA in chromosomes, acting as spools around which DNA strands wrap. These proteins have been well studied, but most current tools to study gene expression rely on RNA sequencing. Histone RNA is unique in that its structure prevents the RNA molecules from being detected by current methods.

Thus, the expression of histone genes may be significantly underestimated in tumor samples. The researchers hypothesized that the increased proliferation of cancer cells leads to a very elevated expression, or hypertranscription, of histones to meet the added demands of cell replication and division.

To test their hypothesis, the researchers used CUTAC profiling to examine and map RNAPII, which transcribes DNA into precursors of messenger RNA. They studied 36 FFPE samples from patients with meningioma – a common and benign brain tumor – and used a novel computational approach to integrate this data with nearly 1,300 publicly available clinical data samples and corresponding clinical outcomes.

In tumor samples, the RNAPII enzyme signals found on histone genes were reliably able to distinguish between cancer and normal samples.

RNAPII signals on histone genes also correlated with clinical grades in meningiomas, accurately predicting rapid recurrence as well as the tendency of whole-arm chromosome losses. Using this technology on breast tumor FFPE samples from 13 patients with invasive breast cancer also predicted cancer aggressiveness.


Using a new technology and computational method, researchers have uncovered a biomarker capable of accurately predicting outcomes in meningioma brain tumors and breast cancers.

Getting mRNA into the brain could allow scientists to instruct brain cells to produce therapeutic proteins that can help treat or prevent disease by replacing missing proteins, reducing harmful ones, or activating the body’s defenses.

The research team designed and tested a library of lipids to optimize their ability to cross the blood-brain barrier. Through a series of structural and functional analyses, they identified a lead formulation, termed MK16 BLNP, that exhibited significantly higher mRNA delivery efficiency than existing lipid nanoparticles approved by the Food and Drug Administration (FDA). This system takes advantage of natural transport mechanisms within the blood-brain barrier, including caveolae-and γ-secretase-mediated transcytosis, to move nanoparticles across the barrier, say the investigators.

In studies using mouse models of disease, the BLNP platform successfully delivered therapeutic mRNAs to the brain, demonstrating its potential for clinical application.


Scientists have developed a lipid nanoparticle system capable of delivering messenger RNA (mRNA) to the brain via intravenous injection, a challenge that has long been limited by the protective nature of the blood-brain barrier.

The findings, in mouse models and isolated human brain tissue, were published in Nature Materials. They demonstrate the potential of this technology to pave the way for future treatments for a wide range of conditions such as Alzheimer’s disease, amyotrophic lateral sclerosis, brain cancer, and drug addiction.

The blood-brain barrier serves as a protective shield, preventing many substances—including potentially beneficial therapies—from reaching the brain. While previous research introduced a platform for transporting large biomolecules such as proteins and oligonucleotides into the central nervous system, this new study focuses on a different approach: using specially designed lipid nanoparticles to transport mRNA across the barrier.

This innovation, called ALA-CART, helps the immune system better recognize and destroy resistant cancers. The new design not only improves treatment success but also promises fewer side effects.

A Powerful Upgrade to CAR-T Therapy

Researchers at the University of Colorado Anschutz Medical Campus have developed an enhanced version of CAR-T cell therapy designed to improve effectiveness and longevity, particularly against cancer cells that were previously difficult to detect and eliminate.

Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the effects aren’t just skin deep. Inside the body, DNA is literally being torn apart.

Understanding how the body heals and protects itself from DNA damage is vital for treating genetic disorders and life-threatening diseases such as cancer. But despite numerous studies and medical advances, much about the molecular mechanisms of DNA repair remains a mystery.

For the past several years, researchers at Georgia State University have tapped into the Summit supercomputer at the Department of Energy’s Oak Ridge National Laboratory to study an elaborate molecular pathway called (NER). NER relies on an array of highly dynamic protein complexes to cut out (excise) damaged DNA with surgical precision.

Over the past two years, the U.S. Centers for Disease Control and Prevention (CDC) has issued Travel Health Advisories focused on measles outbreaks.

These advisories highlight where there is an active health risk when people visit the highlighted countries.

On February 21, 2025, the CDC reissued a Level 1, Practice Usual Precautions, alert for 57 countries. This CDC list does not integrate the Region of the Americas, with numerous countries reporting 537 measles outbreaks this year.

A new analysis reveals complex linkages among the United Nations’ (UN’s) 17 Sustainable Development Goals—which include such objectives as gender equality and quality education—and finds that no country is on track to meet all 17 goals by the target year of 2030.

Alberto García-Rodríguez of Universidad Nacional Autónoma de México and colleagues present these findings in the open-access journal PLOS One.

In 2015, UN member countries adopted the Sustainable Development Goals with the aim of achieving “peace and prosperity for people and the planet.” However, setbacks such as the COVID-19 pandemic, , and have slowed progress, and more research is needed to clarify the underlying obstacles so they can be effectively addressed.
