Posted: 25 Jun 2021 02:32 PM PDT

Researchers are studying a potential new chimeric antigen receptor-T cell therapy (CAR-T cell therapy) treatment for multiple myeloma.

Differences in human, mouse brain cells have important implications for disease research

Posted: 25 Jun 2021 02:31 PM PDT

A study comparing brain cells known as astrocytes in humans and mice found that mouse astrocytes are more resilient to oxidative stress, a damaging imbalance that is a mechanism behind many neurological disorders.

Sleeper cells: Newly discovered stem cell resting phase could put brain tumors to sleep

Posted: 25 Jun 2021 02:31 PM PDT

Biomedical engineering researchers developed a new cell classifier tool that takes a higher-resolution look at the life cycle of neuroepithelial stem cells, which led to the discovery and exploration of a new resting phase called Neural G0. This knowledge could help scientists to better understand glioma brain tumors and develop new methods of treatment.

Having the same nurse for home health visits may prevent rehospitalization for people with dementia

Posted: 25 Jun 2021 09:04 AM PDT

People with dementia receiving home health care visits are less likely to be readmitted to the hospital when there is consistency in nursing staff, according to a new study.

People across the world favor paid parental leave, study finds

Posted: 25 Jun 2021 09:04 AM PDT

Although the United States is the only wealthy nation that doesn't guarantee paid leave to mothers or fathers after the arrival of a new child, Americans endorse providing paid time off for parents nearly as much as people from other countries. About 82% of Americans support paid maternity leave, just slightly less than the 86% who support it in 26 wealthy nations, a new study shows.

Scientists discover how dengue vaccine fails to protect against disease

Posted: 25 Jun 2021 09:04 AM PDT

Researchers discovered that a small subpopulation of antibodies binding to unique sites on each serotype are linked to protection. The research provides important information for vaccine developers to consider when creating a dengue vaccine, which has long eluded scientists.

Putting functional proteins in their place

Posted: 25 Jun 2021 09:03 AM PDT

Using DNA, scientists organized bioactive proteins in desired 2D and 3D ordered arrays -- promising for structural biology, biomedicine, and more.

Bigger may not always be better: Density governs receptor activation on immune cells

Posted: 25 Jun 2021 09:03 AM PDT

Scientists have gained novel insights into how an important class of immune receptors called tumor necrosis factor receptors (TNFR) are activated.

Can a calculator predict your risk of dementia?

Posted: 25 Jun 2021 07:05 AM PDT

Researchers have built and validated an online calculator that empowers individuals 55 and over to better understand the health of their brain and how they can reduce their risk of being diagnosed with dementia in the next five years.

AI used to predict unknown links between viruses and mammals

Posted: 25 Jun 2021 07:05 AM PDT

A new study could help scientists mitigate the future spread of zoonotic and livestock diseases caused by existing viruses. Researchers have used a form or artificial intelligence (AI) called machine-learning to predict more than 20,000 unknown associations between known viruses and susceptible mammalian species.

Small-scale engineering could bring big progress in medical care

Posted: 25 Jun 2021 07:05 AM PDT

Researchers are using bioengineering to trigger and control cell differentiation and transition is expand possibilities for diagnostics, vaccine development and therapeutic treatments.

Early findings of Alzheimer's study in diverse populations now available to researchers

Posted: 24 Jun 2021 05:04 PM PDT

A growing trove of data to help scientists understand the biology of Alzheimer's disease among diverse populations within the context of sociocultural, behavioral and environmental factors is now available.

Muscling up with nanoparticle-based anti-inflammatory therapy

Posted: 24 Jun 2021 01:17 PM PDT

Researchers have developed a new approach in which specifically designed anti-inflammatory nanoparticles (NPs) that could be applied locally and selectively to chronically inflamed muscles severely affected or at more immediate risk of deterioration, and maybe difficult to reach with oral therapeutics.

Genetic discovery could help guide treatment for aggressive childhood cancer

Posted: 24 Jun 2021 01:16 PM PDT

A new study could lead to improved decision making in assigning treatments for children with the aggressive cancer rhabdomyosarcoma after revealing key genetic changes underlying development of the disease.

How immune cells can be trained to fight infections

Posted: 24 Jun 2021 01:16 PM PDT

The body's immune cells fight off microbes and other invaders, and can also be reprogrammed or 'trained' to respond even more aggressively to such threats, report scientists who have discovered the fundamental rule underlying this process in a particular class of cells. Their findings could help pave the way for targeted strategies to enhance the immune system.

Gastrulation research reveals novel details about embryonic development

Posted: 24 Jun 2021 12:26 PM PDT

Scientists revise the current textbook knowledge about gastrulation, the formation of the basic body plan during embryonic development. Their study in mice has implications for cell replacement strategies and cancer research.
