Study uncovers a harmful neutrophil behavior linked to cardiovascular disease

Scientists led by Dr. Andrés Hidalgo at the Centro Nacional de Investigadores Cardiovasculares have discovered that circulating neutrophils - a type of immune cell - acquire different behavior patterns during inflammatory processes.

Statistical analysis reveals less severe COVID-19 outcome due to Omicron variant

A new study demonstrated that in the US, the COVID-19 cases arising after the emergence of the SARS-CoV-2 Omicron variant showed reduced severity of infection than in the cases recorded in previous time points (during the Delta variant outbreak).

Unique nanoparticle can deliver genome editing technology to endothelial cells

The lab of Youyang Zhao, PhD, from Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago developed a unique nanoparticle to deliver genome editing technology, including CRISPR/Cas9, to endothelial cells, which are cells that line blood vessel walls.

Research provides new insights on the architecture of yeast nuclear pore complex

Nuclear pore complexes (NPCs) are massive multi-protein complexes that act as passageways for the transport of molecules into and out of the nucleus.

Researchers discover how the sponginess of stem cell nuclei controls cell differentiation

Researchers from Tokyo Metropolitan University have discovered how the sponginess and stickiness of stem cell nuclei controls how they "differentiate" into specialized cells.

New technique combines bioprinting with cryopreservation to construct frozen structures

A new technique takes bioprinting - in which an ink of cells is printed, layer by layer, to form a structure - to a whole new, and icy level. Investigators from the Zhang lab at Brigham and Women's Hospital have developed a technology that they term "cryobioprinting," a method that uses a bioink embedded with cells to print frozen, complex structures that can be easily stored for later use.

New study shows how cells eat the things around them

A new study shows how cell membranes curve to create the "mouths" that allow the cells to consume things that surround them.

Microgravity likely to contribute to life-saving stem cell advances on Earth

The secret to producing large batches of stem cells more efficiently may lie in the near-zero gravity conditions of space. Scientists at Cedars-Sinai have found that microgravity has the potential to contribute to life-saving advances on Earth by facilitating the rapid mass production of stem cells.

Intestinal organoids used to explain why bats infected with viruses do not succumb to diseases

Experiments attempting to explain why bats can be infected with many viruses at a time without succumbing to diseases such as COVID-19 - knowledge that could help us to reduce the threat to humans of infectious disease - have struggled until now with the fact that live wild bats make poor research subjects.

Researchers suggest hybrid convalescent plasma therapy neutralizes the omicron variant

New research suggests convalescent plasma from unvaccinated donors is not effective against the Omicron variant, however, “hybrid” convalescent plasma from donors who recovered from COVID-19 infection and are vaccinated provides considerable antibody protection.

Human iPSC-derived fallopian tube organoids reveal the origins of common ovarian cancer

Stem cell scientists have revealed the origins of a common ovarian cancer by modeling fallopian tube tissues, allowing them to characterize how a genetic mutation puts women at high risk for this cancer.

New techniques enable visualization of DNA repair machinery in detail

Each one of the trillions of cells that make up the human body suffers more than 10,000 DNA lesions every day. These injuries would be catastrophic if cells were unable to repair them, but a very delicate machinery that detects and repair genetic damage is at work to prevent DNA mutations and diseases such as cancer.

New optogenetic tool uses focused light to reduce actin and myosin-based contractile force

Cell generated force plays essential roles in a wide range of biological processes, such as cell motility, cytokinesis, and tissue morphogenesis. In a study published in Nature Communications, a research team led by the Division of Quantitative Biology at the National Institute for Basic Biology in Japan has successfully developed "OptoMYPT"：an optogenetic tool that utilizes focused light to reduce actin and myosin-based contractile force.

LJI researchers discover how loss of TET enzymes can lead to B cell lymphoma

Scientists at the La Jolla Institute for Immunology have uncovered how loss of TET enzymes can lead to B cell lymphoma. Their research, published in Nature Immunology, could potentially open opportunities for designing drug treatment strategies to target malignant cells in many cancers.

SARS-CoV-2 spreads through cell-to-cell transmission, study finds

The virus that causes COVID-19 has adopted some stealth moves to stay alive and kicking, and one secret to its success is hiding from the immune system by spreading through cell-to-cell transmission, a new study has found.

Researchers unravel how our organs know when to stop growing

The smallest fish in the world, the Paedocypris, measures only 7 millimeters. This is nothing compared to the 9 meters of the whale shark.

Flexibility may maximize the potency of peptides used to treat Type 2 diabetes

A little wiggle room might be just what the doctor ordered. New research suggests that the peptides - short chunks of protein - used to treat Type 2 diabetes may be more effective if they're able to flexibly move back and forth between different shapes.
