Researchers launch startup to revolutionize targeted drug delivery using milk exosomes

Two Nebraska researchers have launched a startup company aimed at bringing to market an innovative method for delivering therapeutics, gene editing tools, plasmids and more to targeted locations in the human body.

Bidirectional movement drives DNA loop formation

Scientists from Delft, Vienna, and Lausanne discovered that the protein machines that shape our DNA can switch direction. Until now, researchers believed that these so-called SMC motors that make loops into DNA could move in one direction only. The discovery, which is published in Cell, is key to understanding how these motors shape our genome and regulate our genes.

Pioglitazone may help prevent painful skin ulcers in people with Werner syndrome

A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 22 on December 2, 2024, entitled "Less frequent skin ulcers among patients with Werner syndrome treated with pioglitazone: findings from the Japanese Werner Syndrome Registry."

Plant chemical discovered to prevent biofilm formation

If your teeth have ever felt fuzzy after skipping a brushing, you've encountered biofilm-a slimy bacterial layer that clings to surfaces. In medical settings, biofilms make infections harder to treat when they form protective shields for bacteria on devices like catheters and implants.

Comorbid atopic diseases affect prognosis of alopecia areata

Asthma, atopic dermatitis or Hashimoto's thyroiditis as concomitant diseases are risk factors for clinical features associated with a poor prognosis in circular hair loss, also known as alopecia areata (AA).

The "Goldilocks" zone: A key to cellular adaptability and resilience

In a discovery that could redefine how we understand cellular resilience and adaptability, scientists at Scripps Research have unlocked the secret interactions between a primordial inorganic polymer of phosphate known as polyphosphate (polyP), and two basic building blocks of life: DNA and the element magnesium.

Eyelashes as natural liquid deflectors for clear vision

Throughout human evolution, body and facial hair have notably diminished, yet eyelashes have remained a distinguishing feature.

Atom probe tomography reveals fluoride patterns in aging teeth

Teeth are essential for helping people break down the food they eat and are protected by enamel, which helps them withstand the large amount of stress they experience as people chew away. Unlike other materials in the body, enamel has no way to repair damage, which means that as we age, it risks becoming weaker with time.

Study links intermittent fasting to slower hair growth

Intermittent fasting has proven benefits for metabolic health, but a new study shows that it could slow hair growth - at least in mice.

Modified chemotherapy regimen for Hodgkin lymphoma reduces long-term side effects

A simple change to the chemotherapy regimen for people with Hodgkin lymphoma could reduce the long-term health impacts that can result from treatment, according to researchers in Cambridge.

Skin-friendly bacteria could revolutionize vaccination

Imagine a world in which a vaccine is a cream you rub onto your skin instead of a needle a health care worker pushes into your one of your muscles.

Caltech develops microrobots for precise drug delivery

In the future, delivering therapeutic drugs exactly where they are needed within the body could be the task of miniature robots. Not little metal humanoid or even bio-mimicking robots; think instead of tiny bubble-like spheres.

Minoxidil found safe and effective for hair loss in breast cancer patients

Hair loss during chemotherapy can cause enough distress for some women to lose self-confidence, which experts say may discourage them from seeking chemotherapy in the first place.

Understanding how the skin's neurons process social touch signals

Two types of neurons in the skin may be particularly important for how the brain interprets social contact between people, according to a new study led by Linköping University in Sweden.

Researchers aim to uncover causes of acquired hearing loss and find potential therapies

With a new five-year, $3.2 million grant from the National Institute on Deafness and Other Communications Disorders, researchers at Case Western Reserve University and Mass Eye and Ear will study what causes acquired hearing loss (AHL) and seek new ways to protect against it.

Biocompatible liquid ink enables scalp-printed electrodes for non-invasive EEG

For the first time, scientists have invented a liquid ink that doctors can print onto a patient's scalp to measure brain activity. The technology, presented December 2 in the Cell Press journal Cell Biomaterials, offers a promising alternative to the cumbersome process currently used for monitoring brainwaves and diagnosing neurological conditions. It also has the potential to enhance non-invasive brain-computer interface applications.

Study challenges long-standing understanding of axon structure

Biology textbooks may need a revision, say Johns Hopkins Medicine scientists, who present new evidence that an armlike structure of mammalian brain cells may be a different shape than scientists have assumed for more than a century.
