Study: Incarcerated people placed in solitary confinement differ significantly from others in prison population
A new study identified groups that are more likely to be placed in extended solitary management (ESM). The study found that individuals sent to ESM differed considerably from the rest of the prison population in terms of mental health, education, language, race/ethnicity, and age.

Protein-based vaccine candidate combined with potent adjuvant yields effective SARS-CoV-2 protection
A new protein-based vaccine candidate combined with a potent adjuvant provided effective protection against SARS-CoV-2 when tested in animals, suggesting that the combination could add one more promising COVID-19 vaccine to the list of candidates for human use.

"Get out of the water!" Monster shark movies massacre shark conservation
Undeniably the shark movie to end all shark movies, the 1975 blockbuster, Jaws, not only smashed box office expectations, but forever changed the way we felt about going into the water - and how we think about sharks.

Routine screening for BI-RADS lesions on automated whole-breast ultrasound
According to ARRS' American Journal of Roentgenology, return to routine screening for BI-RADS 3 lesions on supplemental automated whole-breast ultrasound (ABUS) substantially reduces the recall rate, while being unlikely to result in adverse outcome. This prospective study supports a recommendation for routine annual follow-up for BI-RADS 3 lesions at supplemental ABUS.

Sperm migration in the genital tract: computer simulations identify factors for success
A research team at the Humboldt University Berlin and the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) developed an agent-based computer model to simulate the journey of sperm cells through the female genital tract. Key factors for a successful transit could be identified without the use of animal experiments and were published in the scientific journal "PLoS Computational Biology".

Among spotted hyenas, social ties are inherited
A massive study of data collected over 27 years has shown, for the first time on such a large scale, that a model hypothesizing that a process of social inheritance determines how offspring relationships are formed and maintained is correct. The study, published today in the journal Science, also elucidates the major role that social rank plays in structuring the spotted hyena clan, and how this affects survival.

Professional development opportunities do not delay doctorate training or publications
The NIH funded academic institutions to design programs for professional development through "Broadening Experiences in Scientific Training" (BEST), which includes career panels, skill-building workshops, job-search workshops, site visits, and internships. Because doctoral training is lengthy and requires focused attention on research, some researchers feared students participating in additional training activities might diminish their research productivity or delay graduation. To find out if that was true, research staff from several leading institutions analyzed metrics from ten NIH BEST awardee institutions.

Ovarian follicles derived from mouse pluripotent stem cells produce viable oocytes
Using mouse embryonic stem cells, researchers reconstituted ovarian follicle structures and used them to mature primordial germ cells into fully functional oocytes in vitro, which ultimately produced viable mouse offspring, according to a new report.

Accurate protein structure prediction now accessible to all
Protein design researchers have created a freely available method, RoseTTAFold, to provide access to highly accurate protein structure prediction. Scientists around the world are using it to build protein models to accelerate their research. The tool uses deep learning to quickly predict protein structures based on limited information, thereby compressing the time for what would have taken years of lab work on just one protein. Predicting intricate shapes of proteins vital to specific biological processes could speed treatment development for many diseases.

High-ranking hyena mothers pass their social networks to their cubs
Hyenas inherit their social networks from their mothers, according to research led by biologists Erol Akçay of the School of Arts & Sciences and Amiyaal Ilany of Bar-Ilan University, in collaboration with Kay Holekamp of Michigan State University. The study found this network inheritance effect strongest for offspring of higher-ranking mothers. The finding has implications for how social groups are structured and evolve, the researchers say.

How spiders distinguish living from non-living using motion-based visual cues
Jumping spiders can distinguish living from non-living objects in their peripheral vision using the same cues used by humans and other vertebrate animals, according to a study publishing 15th July 2021 in the open-access journal PLOS Biology by Massimo De Agrò of Harvard University in the United States.

Red blood cell 'traffic' contributes to changes in brain oxygenation
Adequate blood flow supplies the brain with oxygen and nutrients, but the oxygenation tends to fluctuate in a distinct, consistent manner. The root of this varied activity, though, is poorly understood.

Inadequate sequencing of SARS-CoV-2 variants impedes global response to COVID-19
The lack of sequencing of SARS-CoV-2 variants by the U.S. and other countries is imperiling the global response to the COVID-19 pandemic, argues Dana Crawford of Case Western Reserve University in a new Viewpoint published July 15th in the journal PLOS Genetics.

Geneticists outline plan to boost diversity, inclusion in their field
During the ongoing COVID-19 pandemic, a group of geneticists who study the cellular process of meiosis held a virtual discussion of how to boost inclusion of underrepresented groups in their community. Now, Katherine Billmyre of the Stowers Institute for Medical Research, María Angélica Bravo Núñez of Harvard University, Francesca Cole of the University of Texas MD Anderson Cancer Center, and colleagues outline the resulting action plan in an opinion piece for the open-access journal PLOS Genetics.
