Researchers identify a small number of 'cheating' cancer cells under hypoxia

Researchers at UConn Health, Yale, and Johns Hopkins have identified that some cancer cells can "cheat" through escaping constraints imposed by lack of oxygen, allowing the cancer cells to continue to grow.

Cryo-microscopy reveals high-resolution structure of monkeypox virus DNA polymerase holoenzyme

Using cryo-microscopy, researchers present a high-resolution structure of monkeypox virus DNA polymerase holoenzyme, a complex that plays a key role in the genome replication process of the virus.

Researchers develop transgenic mice with the FRET biosensor for in vivo observation of necroptosis

Necroptosis is a form of regulated cell death (RCD) similar to apoptosis, the most commonly studied type of RCD. In contrast to apoptosis, plasma membrane rupture in necroptotic cells occurs at early time points.

Landmark study challenges a 70-year-old theory of protein folding

A landmark study by researchers at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University reveals how a tiny cellular machine called TRiC directs the folding of tubulin, a human protein that is the building block of microtubules that serve as the cell’s scaffolding and transport system.

Study looks at the possibility of promoting hair cell regeneration using cell reprograming

About 430 million people around the world experience disabling hearing loss. In the United States, approximately 37.5 million adults report some trouble hearing. Hearing loss can happen when any part of the ear or the nerves that carry information on sounds to the brain do not work in the usual way.

Research explores cell receptors for bat viruses to understand emergence of zoonotic diseases

New research shows that the closest bat virus relatives of the human Middle-East Respiratory Syndrome (MERS) coronavirus efficiently bind to bat ACE2 receptors as an entry point into these cells.

Discovery of ’raspberry-shaped’ nanoparticle offers a way to enhance the effectiveness of existing drugs

A newly discovered technique, reported in the journal Nanoscale, offers a low-cost way to enhance the effectiveness of existing drugs.

Study shows how ketamine administration starkly changes neuronal activity patterns in the brain

Ketamine, an established anesthetic and increasingly popular antidepressant, dramatically reorganizes activity in the brain, as if a switch had been flipped on its active circuits, according to a new study by Penn Medicine researchers.

Study reveals key details of how DREADD technology highjacks neuronal activity

Understanding of how neuronal activity modulates brain function is a key first step towards creating more effective drugs to treat a variety of neuropsychiatric illnesses, including depression, anxiety, schizophrenia, substance abuse, epilepsy, and others.

Powerful imaging tool creates 3D atlas of the spectrum of tuberculous and COVID-19 lung lesions

Gross anatomy reveals three-dimensional shapes of pathology at a large scale. Histology, in contrast, reveals the microscopic anatomy of biological structures. But that magnification comes at a cost - histology shows only two-dimensional shapes because it studies small, flat slices of stained tissue.

Imaging brain activity deep in the cortex of freely moving mouse

How does the brain produce behavior? Studying the brain during behavior is most informative when the animal is free to interact with its environment in any way it chooses.

Study reveals structural insights into the elusive tankyrase protein that fuels bowel cancer

Scientists have revealed the inner workings of a key protein involved in a wide range of cellular processes – potentially paving the way for better and less toxic cancer drugs.

Bruker announces acquisition of Inscopix for neuroscience research

Bruker Corporation today announced the acquisition of Inscopix, Inc., a neuroscience pioneer and market leader of miniaturized microscopes, known as miniscopes, for freely moving animal brain imaging.

Study illuminates how a typical gut bacterium spreads through the body

A typical gut bacterium that can spread through the body and cause a serious infection resists natural immune defenses and antibiotics by enhancing its protective outer layer, known as the cell envelope, according to a new study by Weill Cornell Medicine investigators.

New tool maps how breast cancer grows in previously unseen detail

New technology can trace which populations of breast cancer cells are responsible for the spread of the disease, and for the first time highlights how the location of cancer cells could be as important as mutations in tumor growth.

Researchers use deep neural networks to virtually stain microscopic images of unlabeled tissue

In the hospital, there is a group of doctors who use tissue samples as "evidence materials", analyze the evidence using knives, slicers and microscopes to extract clues from the tissue samples, and provide patients with "verdicts" - diagnostic reports.

Scientists map structure of the hepatitis C virus E1E2 glycoprotein complex

A team led by scientists at Scripps Research and the University of Amsterdam has achieved an important goal in virology: mapping, at high resolution, critical proteins that stud the surface of the Hepatitis C virus (HCV) and enable it to enter host cells.
