If you enjoy some good toilet technology, then I think “urine” for a treat. Starling Medical is poised to launch its at-home urine diagnostic patient-monitoring platform, dubbed “StarStream,” that doesn’t rely on the traditional catching containers or dipsticks.

Now, if you’re thinking this technology sounds familiar, you would be correct: My colleague Haje Jan Kamps wrote about Withings’ U-Scan, a urinalysis device, earlier this month when the health-focused consumer tech company debuted it at CES. U-Scan also sits in the toilet for at-home monitoring.

However, Alex Arevalos, Starling’s co-founder and CEO, told TechCrunch that this is an underserved market — the global urinalysis market is forecasted to be valued at $4.9 billion by 2026, meaning there is plenty of room for Withings and a scrappy startup.

Three of them were transferred, and two developed. Rachel, who said she had a relatively straightforward pregnancy, gave birth on October 31 at 37 weeks and two days.

Timothy weighed 6 pounds and 7 ounces. Lydia weighed 5 pounds and 11 ounces.

The twins’ record-breaking delivery was verified by the University of Tennessee’s Preston Medical Library. The previous record holder was a child named Molly Gibson, who was born in 2017. The frozen embryo that later became Molly had been stored for 24 years.

Its impressive how adaptive the brain is to each situation. It can sense which portions of the brain need more blood flow depending on energy usage and makes the needed tiny adjustments.

Summary: Researchers identified a specific type of cell that sits on top of the brain’s smallest blood vessels that sense when their region of the brain is in need of energy.

When we smell hot dogs, it may trigger memories of backyard barbeques or attending baseball games during childhood. During this process, the areas of the brain that control smell and long-term memory are rapidly firing off impulses. To fuel these signals from neurons, the active brain regions need oxygen and energy in the form of blood sugar glucose, which is quickly delivered through blood vessels.

Numerous labs across the world have shown that inflammation causes reduced motivation and anhedonia, a core symptom of depression, by affecting the brain’s reward pathways.

An Emory University study published in Nature’s Molecular Psychiatry shows levodopa, a drug that increases dopamine in the brain, has potential to reverse the effects of inflammation on brain reward circuitry, ultimately improving symptons of depression.

I never thought I’d order live human kidney cells to my address, but that all changed when I found out about biohacker Jo Zayner’s at-home genetic engineering class.

You may know Jo Zayner, a “biohacker” who has been in the vanguard of scientific self-experimentation for years, from their role in Netflix’s 2019 docuseries Unnatural Selection. The series shows Zayner attempting to edit their DNA by injecting themselves with CRISPR, a gene-editing technology. The action inspired a firestorm of criticism.

Zayner is also known for a variety of other bold moves, such as claiming to create a DIY at-home COVID vaccine in 2020 and executing their own fecal microbiome transplant.

Greater diversification could help agriculture withstand climate, economic and geopolitical crises.

“Items in this section have limited availability due to supplier production issues,” “Sorry, temporarily out of stock” and “Sold out” are all signs that became familiar as recent global upheavals exposed how precarious our food supply is.

The COVID-19 pandemic led to bare shelves in supermarkets as shipping routes were cut off. The war in Ukraine has affected the supply of essential grains.

CRISPR may be in for a fight thanks to this new, faster, safer, AI-powered zinc-finger gene-editing technique.

A new study has developed what the researchers call the “world’s first” simple, modifiable proteins. Called “zinc fingers,” these special proteins were developed partially through artificial intelligence.

Scientists from the University of Toronto and the NYU Grossman School of Medicine came up with the method, which is expected to speed up the development of gene therapies. This could be a game-changer for how doctors treat DNA mistakes that happen over time. This is partly because our genes change naturally as we age, which makes it inevitable that mistakes will happen. Or, of course, from genetic disorders inherited at birth.

According to the U.S. Centers for Disease Control and Prevention, more than 40% of people living in the U.S. are obese; and 43% of American women over the age of 60—long past menopause—are considered obese. A recent Johns Hopkins study showed that a drug first developed to treat Alzheimer’s disease, schizophrenia, and sickle cell disease could treat obesity and fatty liver and improve heart function—without changes in food intake or daily activity.
