Researchers find molecule that halts, reverts neurodegeneration caused by Parkinson's disease

The small SynuClean-D molecule interrupts the formation of the alpha-synuclein amyloid fibers responsible for the onset of Parkinson's disease, and reverts the neurodegeneration caused by the disease.

Genomic ‘islands’ evolved from viruses can be converted into ‘anti-bacterial drones’

Genomic "islands" that evolved from viruses can be converted into "drones" that disable Staphylococcus aureus, bacteria that are often resistant to antibiotics and pose a threat to safe hospital care, a new study finds.

Environmental biologist explores how songbirds stay slim despite overeating

Noticing that songbirds, such as finches, never seem to get fat despite overeating at bird feeders, London environmental biologist Lewis Halsey wondered whether the amount of energy birds put into singing, fidgeting, or exercising could be adjusted in ways that regulate weight.

New research provides insight into the way human brain connects episodic memories to solve problems

Humans have the ability to creatively combine their memories to solve problems and draw new insights, a process that depends on memories for specific events known as episodic memory.

Scientists discover and characterize human skeletal stem cells

Human skeletal stem cells that become bone, cartilage, or stroma cells have been isolated from fetal and adult bones. This is the first time that skeletal stem cells, which had been observed in rodent models, have been identified in humans.

Ecstasy drug makes octopuses more social

When people take MDMA, the drug popularly known as ecstasy, a rush of serotonin, dopamine, and oxytocin produces feelings of emotional closeness and euphoria, making people more interested than they would normally be in connecting and sharing with other people.

Researchers propose mechanism by which ASTN2 protein defects lead to brain disorders

In the brain, as in business, connections are everything. To maintain cellular associates, the outer surface of a neuron, its membrane, must express particular proteins--proverbial hands that reach out and greet nearby cells. And, like a creepily long handshake, surface molecules can overstay their welcome: A protein that lingers too long on the membrane may compromise the connections, or synapses, between cells.

Overlooked immune cells could play a key role in cancer immunotherapy, claims new study

Cancer immunotherapy is a relatively new method of treating cancer and has succeeded with some refractory tumors. However, it doesn’t always work, why not?

Scientists report conserved role for serotonin in mediating social behavior in octopus, humans

The mood-altering drug MDMA - which promotes positive, friendly social interactions in humans by inhibiting serotonin uptake in nerve cells - has a similar behavioral effect in an octopus species, scientists report today.

Novel mathematical approach uncovers existence of unsuspected biological cycles

A novel mathematical approach has uncovered that some animal cells have robust 12-hour cycles of genetic activity, in addition to circadian or 24-hour cycles.

Body organs undergo structural changes in response to diet

Body organs such as the intestine and ovaries undergo structural changes in response to dietary nutrients that can have lasting impacts on metabolism, as well as cancer susceptibility, according to Carnegie's Rebecca Obniski, Matthew Sieber, and Allan Spradling.

Progenitor cells for human bone and cartilage have been identified

Research published today describes for the first time the identification of human skeletal stem cells. The discovery may enable the development of novel therapeutic strategies for diseases that cause skeletal degeneration.

Study finds factors within cell influencing variability in amount of protein produced

You can think of a cell in your body like a miniature factory, creating a final product called proteins, which carry out various tasks and functions.

New study focuses on two-way gene switches controlling gene activity

Led by ICREA research professors at the Centre for Genomic Regulation, Luciano Di Croce and Marc A. Marti-Renom, the study focused on a set of genes with what's known as bivalent promoters - two-way genetic 'control switches' that are poised either to turn on in early development and rapidly drive high levels of gene activity, or to switch off and shut down the gene completely.

New chemo-optogenetic method enables multi-directional activity control of cellular processes

Cells need for reactions on environmental changes and a balanced system of signaling cascades within the cell. Proteins outside of the cell, on the cellular surface, inside the cellular membrane, and within the cell orchestrate many fine-tuned signaling pathways, which result in adequate reactions on the environmental conditions or changes in the organism itself.
