If a free-floating brain could feel pain or ‘wake up,’ how would we know? That’s an important ethical question — and it’s one we need to ask more often as labs around the world create new organoids, or miniature human organs. To answer it we talked to Jay Gopalakrishnan at his ‘mini brain’ lab for centrosome and cytoskeleton biology in Düsseldorf, Germany.

A paralyzed individual controls a neuroprosthetic without daily recalibration.

As big pharma interest grows in bioelectronics medicine, Astellas swoops in for a startup developing wireless, grain-sized devices powered by ultrasound for CNS disease monitoring and intervention.

If “junk” DNA goes toxic, does that suggest it had an original normal function? See the conclusion of this new paper, “Native functions of short tandem repeats” (emphasis added):

Historically, repetitive elements within human genomes have been viewed as mostly unregulated ‘junk DNA’ that is not under selective evolutionary pressure. As such expansions of these repetitive elements are unfortunate accidents which become apparent and important only when they elicit highly penetrant and syndromic human diseases. Consistent with this line of reasoning, the field of REDs [Repetitive Element Diseases] has largely focused on emergent toxic mechanisms as drivers of disease only in the setting of large STR [Short Tandem Repeats] expansions rather than considering their pathology as alterations in the native functions played by these repeats in their normal genomic contexts. Here, we propose re-framing the discussion around repetitive elements in general — and STRs in particular — within human genomes.

For a while now, we’ve known there’s a complex interplay between our hormones, guts, and mental health, but untangling the most relevant connections within our bodies has proved challenging.

New research has found a single enzyme that links all three, and its presence may be responsible for depression in some women during their reproductive years.

Wuhan University medical researcher Di Li and colleagues compared the blood serum of 91 women aged between 18 and 45 years with depression and 98 without. Incredibly, those with depression had almost half the serum levels of estradiol – the primary form of estrogen our bodies use during our fertile years.

The human body is made up of thousands of tiny lymphatic vessels that ferry white blood cells and proteins around the body, like a superhighway of the immune system. It’s remarkably efficient, but if damaged from injury or cancer treatment, the whole system starts to fail. The resulting fluid retention and swelling, called lymphedema, isn’t just uncomfortable—it’s also irreversible.

When lymphatic vessels fail, typically their ability to pump out the fluid is compromised. Georgia Institute of Technology researchers have developed a new treatment using nanoparticles that can repair lymphatic vessel pumping. Traditionally, researchers in the field have tried to regrow lymphatic vessels, but repairing the pumping action is a unique approach.

“With many patients, the challenge is that the lymphatic vessels that still exist in the patient aren’t working. So it’s not that you need to grow new vessels that you can think of as tubes, it’s that you need to get the tubes to work, which for lymphatic vessels means to pump,” said Brandon Dixon, a professor in the George W. Woodruff School of Mechanical Engineering. “That’s where our approach is really different. It delivers a drug to help lymphatic vessels pump using a nanoparticle that can drain into the diseased vessels themselves.”

Growing brains can be a tricky process, but growing ones that can make muscles move? That’s an incredible feat. Here’s how scientists did it.

Researchers at Texas A&M University have developed the first molecular therapeutic for Angelman syndrome to advance into clinical development.

In a new article, published today in Science Translational Medicine, Dr. Scott Dindot, an associate professor and EDGES Fellow in the Texas A&M School of Veterinary Medicine and Biomedical Sciences’ (VMBS) Department of Veterinary Pathobiology, and his team share the process through which they developed this novel therapeutic candidate, also known as 4.4.PS.L, or GTX-102. Dindot is also the executive director of molecular genetics at Ultragenyx, which is leading the development of GTX-102.

Angelman syndrome (AS) is a devastating, rare neurogenetic disorder that affects approximately 1 in 15,000 live births per year; the disorder is triggered by a loss of function of the maternal UBE3A gene in the brain, causing developmental delay, absent speech, movement or balance disorder, and seizures.
