Newly identified B-cell selection process adds to understanding of antibody diversity

Researchers at Beth Israel Deaconess Medical Center have identified a new B-cell selection process that influences antibody survival independent of antigen-binding regions. This discovery adds a surprising dimension to the understanding of antibody repertoires and may help shape them to better fight disease.

Did violence shape our faces?

Researchers propose that human faces developed robust features to protect against facial injuries during hand-to-hand combat, challenging the long-held hypothesis that these traits arose from eating hard foods. The study's findings support the idea that violence played a significant role in shaping human evolution.

Designing ion 'highway systems' for batteries

A Northwestern University team has developed a new understanding of plastics for battery applications by combining two traditional theories in materials science. This opens the door for a new class of batteries with improved safety and power efficiency. The researchers used block copolymers, which are self-assembling into nanostructure...

'Jekyll and Hyde' protein linked to type 1 diabetes

A new study published in PNAS reveals how the GAD65 protein changes shape when activated, potentially linking it to type 1 diabetes. The research found that antibodies interact with the protein differently depending on its state, which may affect vaccine development for the disease.

Protein could put antibiotic-resistant bugs in handcuffs

Researchers at Duke University have identified a key protein that drives DNA copying in plasmids responsible for antibiotic resistance in staphylococcus bacteria. By understanding how this protein works, scientists may develop new ways to prevent the spread of antibiotic-resistant plasmids.

Antiviral therapy may prevent liver cancer in hepatitis B patients

A study of over 2,600 adults with hepatitis B found that antiviral therapy significantly reduced the occurrence of liver cancer (HCC) by 60%. The therapy was more effective than treatment in preventing HCC than untreated patients. Results suggest a potential new approach to preventing a common and deadly form of cancer.

Exercise boosts diversity of gut bacteria

A study of professional rugby players found that exercise increased the diversity of gut microbiota, which was positively correlated with a favourable metabolic profile and immune system response. Higher dietary protein intake also played a role in this association.

Most breast cancer patients may not be getting enough exercise

Breast cancer patients often do not meet national physical activity guidelines after diagnosis, with African-American women being less likely to do so. A study found that only 35% of survivors met guidelines post-diagnosis, with a significant decrease in activity six months after diagnosis.

First atlas of Inuit Arctic trails launched

Researchers have mapped ancient Inuit trails using archival accounts, maps, and place names, providing a vital step in cultural preservation and understanding Inuit history. The 'pan-Inuit' world is being fragmented due to climate change, but the atlas shows the geographical extent and connectedness of Inuit occupancy.

New teaching approach touted for engineering education

Purdue researchers have developed a new approach to teach large numbers of engineering students, resulting in improved student performance and engagement. The Purdue Mechanics Freeform Classroom system allows students to interact online while accessing instructional videos and animations, reducing the number of students who receive a D...

Berkeley Lab researchers create nanoparticle thin films that self-assemble in 1 minute

Researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory have devised a technique to form highly ordered thin films over macroscopic distances in one minute. The technique uses supramolecules based on block copolymers to create nanocomposites that self-assemble into hierarchically-structured thin films.
