Leveraging optofluidics to make therapeutic antibody discovery easier
May 10, 2021 -- The need for speed and accuracy in the development of therapeutic antibodies has prompted Berkeley Lights to upgrade its optofluidic tools to help customers improve the quality of their therapeutic antibody products. John Proctor, PhD, senior vice president of antibody therapeutics at Berkeley Lights, spoke with ScienceBoard.net about some technological advancements the company has recently launched. Read More
Preparation is key for postdocs to transition to industry positions
May 7, 2021 -- Postdoctoral positions are a natural choice for many scientists who have just received their PhDs. Postdocs allow scientists to gain invaluable research experience and training under guided mentorship -- and potentially transition to industry jobs, explains Natalia Martin, PhD, a program manager at the American Chemical Society.

Tiny mechanical forces can have a massive effect on T-cell activation
May 6, 2021 -- A new study reveals how tiny forces between T cells and their targets can help to jumpstart protective immune responses. Research published in Nature Communications on May 4 uses cutting edge microscopy techniques to track the association and dissociation between T cells and antigens. Read More
Hope for next-gen COVID-19 vaccines may rest in an unexpected region of the virus
May 5, 2021 -- Researchers further elucidated how antibodies produced in people who effectively fight off SARS-CoV-2 work to neutralize the part of the virus responsible for causing infection. The study, published in Science on May 4, describes how antibodies targeting sections of the virus outside of the receptor-binding domain may be useful in the development of vaccines and therapies.

Life after academia: Industry can offer new opportunities for scientists
May 4, 2021 -- For many scientists working in academia, the idea of switching careers to industry can be intimidating. But many scientists are making the move and are finding corporate work to be just as rewarding. One of them is Anuraag Sarangi of medical communications firm Precisionscientia. Read More
Single-cell atlas of human teeth exposes root of stem cell behavior
May 3, 2021 -- The first comprehensive single-cell atlas of the human tooth reveals how different dental tissues control the activity of stem cells. Published recently in iScience, the study used advanced single-cell sequencing technology to show that changes in the cellular environment may explain differences in the behavior of stem cells.

How one cell transplant platform is poised to tackle complex diseases
April 30, 2021 -- Lineage Cell Therapeutics CEO Brian Culley discusses the company's cell therapy technology with ScienceBoard.net. The technology involves the transplantation of differentiated stem cells as part of an off-the-shelf allogeneic cell therapy. Read More
How the South African SARS-CoV-2 variant evades antibodies
April 29, 2021 -- Computer modeling has demonstrated that one of the three mutations of the South African SARS-CoV-2 variant reduces its ability to bind to human cells. The results, published recently in the Journal of Medicinal Chemistry, also suggest that the mutation may help it escape some therapeutic antibodies. Read More
New method allows for study of genetic changes in individual DNA molecules
April 28, 2021 -- An improved sequencing method, called nanorate sequencing, allows for the study of genetic changes in human cells with unprecedented accuracy. The new technique, published in Nature on April 28, challenges the idea that cell division is the main mechanism driving genetic changes. Read More
New tool sheds light on transient protein interactions in cells
April 27, 2021 -- Researchers have developed a novel chemical tool for elucidating protein interaction networks within cells. The technique, details of which were published in Molecular Cell on April 23, allows for the visualization of protein-protein interactions. Read More
Nanoparticles may offer new way to tackle antibiotic-resistant bacteria
April 26, 2021 -- A team of researchers has developed nanoparticles that use a completely different mode of action from conventional antibiotics. These inorganic nanoparticles have inherent antimicrobial properties and can target pesky bacteria that hide inside of cells. The results were published in Nanoscale on April 22. Read More
Naturally occurring molecule helps SARS-CoV-2 evade neutralizing antibodies
April 23, 2021 -- Researchers have identified naturally occurring molecules that are created from the breakdown of hemoglobin and block the binding of a subset of human antibodies to SARS-CoV-2. The discovery, published in Science Advances on April 22, may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus. Read More
Cell-free technique could enable on-demand vaccine production
April 22, 2021 -- A new cell-free synthetic biology technique that increases the volume of membrane components in the manufacture of conjugate vaccines can significantly improve the efficiency of vaccine production, according to a new method published in Nature Communications on April 22. The technology could enable on-site production of vaccines and therapies, enabling them to be more efficiently distributed in areas where they are most needed. Read More
Scientists map gene expression without microscopes
April 21, 2021 -- A new framework called Tomographer, which uses sequencing data from tissues cut into thin strips in a way that allows them to be reconstructed, has been developed to spatially resolve gene expression data without the need for a microscope. The work was published in Nature Biotechnology on April 19. Read More
New algorithm helps integrate single-cell data from around the globe
April 20, 2021 -- A new algorithm enables researchers from around the globe to integrate multiple single-cell datasets from a variety of omics platforms in a quick and efficient process that can be done on standard computers. The technology, described in an April 19 Nature Biotechnology article, will help speed collaborative cell cataloging projects, such as the Human Body Map and Human Cell Atlas. Read More
