Researchers produce complete 3D structure for yeast Nuclear Pore Complex

For the first time, researchers have produced a nearly complete three-dimensional structure for the yeast Nuclear Pore Complex. This discovery represents a major step toward identifying the atomic structure of the NPC, which soon may provide researchers with a better understanding of how the central transport channel functions.

Researchers create cardiomyocyte molds to mend broken hearts

2.5 billion. That's approximately the number of times the human heart beats in 70 years. And sometimes during the course of its unrelenting contractions and relaxations, the heart muscle can no longer bear the strain.

NIH-funded researchers use CRISPR to rapidly find new genetic suspects behind ALS, FTD

NIH-funded researchers at Stanford University used the gene editing tool CRISPR-Cas9 to rapidly identify genes in the human genome that might modify the severity of amyotrophic lateral sclerosis and frontotemporal dementia caused by mutations in a gene called C9orf72.

Scientists uncover detailed map of the brain circuits behind thirst and satiety

Scientists uncovered a high-resolution map of the wiring inside the mouse brain's thirst center. With these blueprints, they could trick mice into becoming light or heavy water drinkers.

Study reveals key function of ALS-linked protein

The protein FUS, whose mutation or disruption causes many cases of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), works as a central component of one of the most important regulatory systems in cells, according to a new study in Molecular Cell from scientists at Johns Hopkins Bloomberg School of Public Health.

Study findings establish basis for epigenetic link between aging and Alzheimer's disease

Although certain genetic variants increase the risk of Alzheimer's disease (AD), age is the strongest known risk factor. But the way in which molecular processes of aging predispose people to AD, or become impaired in AD remains a mystery.

MIPT biophysicists study structure and interaction of nanofibrous scaffold with cardiac cells

Biophysicists from MIPT have studied the structure of a nanofibrous scaffold, as well as its interaction with rat cardiac cells.

Study sheds light on a key protein associated with brain diseases and dementia

A new study has increased understanding of the connection between angiogenin and neurological disorders such as ALS and Fronto-temporal dementia.

Caltech scientists map neural circuit that regulates thirst

There are few feelings more satisfying than gulping down water when you are thirsty. But how does your brain know when you are dehydrated or satiated, and how does it use this information to initiate or terminate drinking? Caltech scientists have now mapped the circuit of neurons within the mouse brain that regulates thirst by stimulating and suppressing the drive to drink water.

Telomere length testing can alter treatment decisions for certain diseases

Research led by Johns Hopkins physicians and scientists shows that a test for measuring the length of DNA endcaps, called telomeres, which has a variability rate of 5 percent, can alter treatment decisions for patients with certain types of bone marrow failure.

Researchers discover key inner control mechanism of cell's 'smart glue'

Researchers at St. Jude Children's Research Hospital have discovered that a protein critical to a process called liquid-liquid phase separation within the cell undergoes internal changes in conformation that are key to its function.

Researchers discover new regulator of the immune system

Academy Professor Riitta Lahesmaa's research group from Turku Centre for Biotechnology of the University of Turku and Åbo Akademi University, Finland, has discovered a new regulator of the immune system, a key factor that controls development of regulatory T cells.

Brain's quality control process holds clues to obesity's roots

Deep in the middle of our heads lies a tiny nub of nerve cells that play a key role in how hungry we feel, how much we eat, and how much weight we gain. Around the clock, they produce a "grandfather" form of several hormones that help us regulate these crucial functions.

Scientists develop ultrasound-propelled nanomotors for active delivery of Cas9-sgRNA complex

In cancer research, the “Cas-9–sgRNA” complex is an effective genomic editing tool, but its delivery across the cell membrane to the target (tumor) genome has not yet been satisfactorily solved. American and Danish scientists have now developed an active nanomotor for the efficient transport, delivery, and release of this gene scissoring system.

DNA plays unexpected architectural role in shaping cells, study finds

As a basic unit of life, the cell is one of the most carefully studied components of all living organisms. Yet details on basic processes such as how cells are shaped have remained a mystery.

Mitochondrial DNA may play more important role in metastatic cancer than previously thought

DNA found in the mitochondria may play a more significant role in metastatic cancer than originally thought.

Ribosomes found to be cause of somatic cell pluripotency

In 2012, a Japanese research group discovered that human skin cells acquire pluripotency when introduced to lactic acid bacteria. Now, the same group of researchers have found that the cause of somatic cell conversion into pluripotent stem cells is the ribosome, a protein synthesizing cellular organelle.

Inhaled carbon dioxide triggers group of neurons responsible for arousal

Breathing too much carbon dioxide can be deadly, but it can happen during sleep if a particular sleeping position causes an obstructed airway or because of a medical condition like sleep apnea.

The effects of Huntington’s disease can be seen as early as conception, finds new study

In a breakthrough study, scientists at the Rockefeller University have observed the effects of Huntington’s disease in neurons as early as conception.

Small tweak to mammal's DNA can cause significant physical changes, study finds

The difference between webbed toes and distinct digits may be the result of not just genetic information, but of how the genes regulate that information. Researchers at the National Institute of Genetics, Research Organization of Information and Systems in Japan found that a small, non-specific tweak to a mammal's DNA can potentially cause specific and significant physical changes.
