Berkeley Lab and Genentech Team Up to Develop Next-Generation Drug Delivery System

Many diseases can be successfully treated in the simple environment of a cell culture dish, but to successfully treat real people, the drug agent has to take a journey through the infinitely more complex environment within our bodies and arrive, intact, inside the affected cells.

5-ALA Opens New Avenues for Treating Mitochondrial Disorders

At the Tokyo Metropolitan University, researchers have shown that 5-aminolevulinic acid (5-ALA) aids bypass deficiencies in Complex I (CI), the first in a series of protein complexes that transport electrons and assist in powering the mitochondria.

Xenogeneic-Free Brain Organoids Offer New Hope for Studying Neurodegenerative Diseases

Researchers at University of Michigan developed a method to produce artificially grown miniature brains -; called human brain organoids -; free of animal cells that could greatly improve the way neurodegenerative conditions are studied and, eventually, treated.

Metabolic Systems Share Previously Unknown Universal Properties: Study

A team from the University of Tokyo has combined economic theory with biology to understand how natural systems respond to change. The researchers noticed a similarity between consumers' shopping behavior and the behavior of metabolic systems, which convert food into energy in our bodies. The team focused on predicting how different metabolic systems might respond to environmental change by using an economic tool called the Slutsky equation.

Scientists Discover How Brain's "Population Clock" Guides Behavior

From Aristotle's musings on the nature of time to Einstein's theory of relativity, humanity has long pondered: how do we perceive and understand time? The theory of relativity posits that time can stretch and contract, a phenomenon known as time dilation. Just as the cosmos warps time, our neural circuits can stretch and compress our subjective experience of time. As Einstein famously quipped, "Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute".

Novel Drug Compound Reduces Sensory Hypersensitivity in Fragile X Mice

Boosting the activity of inhibitory interneurons in Fragile X mice reduced their hypersensitivity to sensory stimuli, according to a new Neuron study led by UCLA Health researchers.

Mast Cells May Help Humans Avoid Harmful Antigens

Mast cells, which are part of the immune system, are still a puzzle. Mast cells function as a sensor that signifies the animals to avert antigens, including harmful allergens, and thus safeguard themselves from health-threatening inflammatory reactions, according to researchers at the German Cancer Research Center (DKFZ). The research was published in the journal Nature.

First 'Living Digital Camera' Stores Images in DNA

In a world first, a 'biological camera' bypasses the constraints of current DNA storage methods, harnessing living cells and their inherent biological mechanisms to encode and store data.

New Insights Into How Genes Are Activated

Genetic information contained within DNA has to be read by specific proteins that enable the process of gene activation to begin – but in many cases, these proteins can't access their targets because DNA strands are bundled up to control what genes are used in the wide range of different cell types.

Glucose-Sensing Neurons May Play a Role in Regulating Blood Sugar

The body's blood glucose level needs to be maintained in a relatively narrow range. It cannot be too high, as it can lead to diabetes, and it cannot be too low because it can cause fainting or even death.

Live Broadcasting of “Growth Factor Signaling” Proteins Inside Living Cells

The “live reporter” technology, developed by synthetic biologists at Princeton University and Rice University, has shown that it is possible to expose, with a great deal more accuracy than is now possible, the functioning of networks of signaling proteins in living cells.

Research may Offer a New Way to Break Through Cancer's Hypoxia-Induced Defenses

For most of our tissues and cells, a lack of oxygen, or hypoxia, is bad news. Cancer cells, on the other hand, can thrive in these hypoxic conditions, which render tumors less susceptible to anti-cancer treatments, including radiation.
