First molecular images of olfaction sets the stage to create novel smells

Breaking a longstanding impasse in our understanding of olfaction, scientists at UC San Francisco (UCSF) have created the first molecular-level, 3D picture of how an odor molecule activates a human odorant receptor, a crucial step in deciphering the sense of smell.

Uncovering the complete 3D structure of p53 protein

By inducing cell repair or self-destruction, the tumor suppressor protein p53, often known as “the guardian of the genome,” shields the body’s DNA from daily stress or long-term damage.

Accelerating the structure-guided discovery of chemogenetic tools

In order to more fully understand how diseases arise in the brain, scientists must unravel the intricate way neurons relay messages (either chemical or electrical) along a complex web of nerve cells. One way is by using a tool called DREADDs, which stands for Designer Receptors Activated by Designer Drugs.

New method triggers and analyzes the dynamics of brain protein linked to Alzheimer’s

Scientists are not yet clear on how the tau protein changes from a benign protein essential for normal function in our brains into the toxic neurofibrillary tangles that are a signature of Alzheimer's and other neurodegenerative diseases.

Study elucidates the structure of centromeric region in chicken cells

The genetic material inside cells is organized into structures called chromosomes. The centromere is essential for the correct division of the chromosomes via interaction with spindle microtubules when cells divide and grow.

Structure of amyloid fibers formed by the protein hnRNPDL-2 determined

Using high-resolution cryo-electron microscopy (cryo-EM), UAB researchers determined the structure of amyloid fibers formed by the protein hnRNPDL-2, which has been linked to limb-girdle muscular dystrophy type 3 and concluded that the protein’s inability to form amyloid ﬁbers, rather than aggregation, would be the cause of the disease.

Countering climate change with nanowires produced by bacteria

Rapid climate change poses a serious and immediate threat to life on Earth. As atmospheric methane traps heat 30 times more effectively than CO2, temperatures are rising as a result.

A 3D explanation of SPOP’s role in cancer

The protein SPOP, which also plays a role in endometrial, uterine, and other cancers, is the most mutated in prostate cancer. Despite its significance, it is still unclear how SPOP mutations cause cancer.

Analyzing the regulatory mechanisms of enzyme production in mold

Filamentous fungi have long been a close ally of sake brewers, but they may soon become associates of environmentalists as well. Scientists from Osaka Metropolitan University discovered the regulatory mechanisms of enzyme synthesis in a filamentous fungus, allowing for the effective degradation of plant biomass, an alternative energy resource to petroleum.
