Researchers identify novel genetic signature with prognostic value for certain breast cancers

Researchers have identified a genetic signature with prognostic value for certain kinds of breast cancer. The discovery also contributes to a better understanding of the molecular mechanisms of pathological angiogenesis, the aberrant proliferation of blood vessels that occurs during cancer and other diseases.

High-fat meal can silence gut's communication with the body, study shows

A high-fat meal can silence communication between the intestine and the rest of the body, according to a new Duke University study in zebrafish.

Brazilian researchers create hepatic organoids by 3D bioprinting

Using human blood cells, Brazilian researchers have succeeded in obtaining hepatic organoids ("mini-livers") that perform all of the liver's typical functions, such as producing vital proteins, storing vitamins, and secreting bile, among many others.

Researchers identify molecular machinery that drives rapid polymerization of actin filaments

Many cells in our body constantly change their shape and move within our tissues. For example, wound healing and the immune system depend on migrating cells.

Using bacterial nano-syringes as drug transporters in medicine

Pathogens can use a range of toxins to damage their host organism. Bacteria, such as those responsible for causing the deadly Plague, use a special injection mechanism to deliver their poisonous contents into the host cell.

Research finds key reason why brain connectivity goes awry in rare neurodevelopmental conditions

Axons are the long thread-like extensions of neurons that send electrical signals to other brain cells. Thanks to axonal connectivity, our brains and bodies can do all necessary tasks.

Penn researchers track defective sperm epigenome linked to male infertility

One out of eight couples has trouble conceiving, with nearly a quarter of those cases caused by unexplained male infertility. For the past decade, research has linked that infertility to defective sperm that fail to "evict" proteins called histones from DNA during development.

Scientists modify approved cancer drug to develop new antibiotic

Antibiotic-resistant bacteria are increasingly the source of deadly infections. A team of scientists from the Technical University of Munich and the Helmholtz Center for Infection Research in Braunschweig have now modified an approved cancer drug to develop an active agent against multidrug-resistant pathogens.

Super-resolution localization photoacoustic microscopy can find blocked or burst blood vessels

200 years ago, a doctor from France used a stethoscope for the first time and countless efforts to observe human body have been made since then. Up to now, the best tool that provides anatomical, functional, and molecular information of human and animal is the photoacoustic microscopy.

New concepts for efficient, reliable risk assessment of nanomaterials

From dyes to construction materials, and from cosmetic products to electronics and medicine, nanomaterials are found in many different applications. But what are these materials? "Nanomaterials are defined purely by their size," explains Dr Kristin Schubert from the Department of Molecular Systems Biology at UFZ.

Salk researchers uncover new function of mitochondria

Mitochondria, tiny structures present in most cells, are known for their energy-generating machinery. Now, Salk researchers have discovered a new function of mitochondria: they set off molecular alarms when cells are exposed to stress or chemicals that can damage DNA, such as chemotherapy.

New techniques could help neuroscientists track brain computations

Since the 1950s at least, researchers have speculated that the brain is a kind of computer in which neurons make up complex circuits that perform untold numbers of calculations every second. Decades later, neuroscientists know that these brain circuits exist, yet technical limitations have kept most details of their computations out of reach.
