Elucidation of mitochondrial membrane pore formation

Human metabolism depends on mitochondria, which are regarded as the power plants of cells. But since 40% of the proteins in the mitochondria are dysfunctional and are linked to human diseases, mitochondria also play a significant role in medical research.

Scandinavian gene pool development via DNA analysis

The complex relationships between geography, ancestry, and gene flow in Scandinavia are resolved in a new study based on 297 ancient Scandinavian genomes that were analyzed along with the genomic data of 16,638 modern Scandinavians.

Uncovering new function for small RNAs in Salmonella infections

Millions of people get sick from Salmonella each year because they are food-borne pathogens. These bacteria rely on a sophisticated network of genes and gene products that give them the ability to sense environmental conditions to do this.

Ultrafast, highly sensitive detection of proteins using simple laser irradiation

Protein detection based on antigen–antibody reaction is vital in early diagnosis of a wide range of diseases. How to effectively detect proteins, however, has frequently bedeviled researchers.

Key immune alarm protein that regulates inflammation identified

Trinity researchers have made a significant advance in understanding how inflammation is controlled. They recently discovered that a crucial immunological alarm protein that was previously thought to quiet the immune response apparently performs the opposite.

New DNA analysis leads to first accurate tuberculosis genome identification

A novel genome assembly tool that has been created by researchers could lead to the creation of fresh antibiotics for the bacterial infections that cause tuberculosis and other diseases.

CT scanning and 3D modeling shed light on evolution of pelvic fins in shark embryos

Curtin University researchers have revealed how the pelvic fins of fish such as sharks and chimeras have evolved from their sudden appearance in the fossil record over 410 million years ago.

Octopuses' acuity may provide a critical link in understanding the evolution of complex life

Octopuses have captured the attention of scientists and the public with their remarkable intelligence, including the use of tools, engaging in creative play and problem-solving, and even escaping from aquariums.

Involvement of the piRNA pathway in brain plasticity and successful aging

The Neurobiology of miRNA team, headed by Davide De Pietri Tonelli of the Istituto Italiano di Tecnologia (IIT-Italian Institute of Technology), established a link between a family of small RNA molecules known as piRNAs and brain inflammation.

The potential of cellular “glue” in regenerative medicine

Scientists at UC San Francisco have created molecules that function as “cellular glue,” enabling them to precisely control how cells adhere to one another. The discovery is a significant step toward regenerative medicine’s long-term goal of creating new tissues and organs.

Ancient environmental DNA used to map a two-million-year-old ecosystem

Around 2 million years ago climate in Greenland resembled that forecasted under future warming containing trees such as poplars and birch and animals like hare, lemmings, mastodons and reindeer.

FSU study shows the transgenerational transmission of aspartame-induced anxiety in mice

Florida State University College of Medicine researchers have linked aspartame, an artificial sweetener found in nearly 5,000 diet foods and drinks, to anxiety-like behavior in mice.

Revealing the unappreciated role of POLQ in responding to DNA replication stress

Researchers at the Francis Crick Institute, in partnership with Artios, have discovered how an enzyme involved in DNA repair (POLQ) becomes critical to the survival of some tumors when the cancer cells lose the ability to employ a more frequent way of DNA repair.

Three-year interval appropriate between screening for colorectal cancer

Three years after the first negative multi-target stool DNA test, according to a scientific investigation into the best time to screen for colorectal cancer using non-invasive methods for detecting the disease’s targets in the stool, there were no colorectal malignancies discovered.

Bats use distinct laryngeal structures to generate echolocation and social calls

Bats use distinct structures in the larynx to produce high-frequency echolocation calls and lower-frequency social calls, according to a study by Coen Elemans at the University of Southern Denmark and colleagues, publishing November 29th in the open access journal PLOS Biology.
