More intense predation in the tropics can limit marine invasions

Posted: 25 Jun 2021 12:56 PM PDT

Marine biologists tested predictions about biological invasions, first in Panama and then in an experiment of unprecedented geographic scale.

Engineered yeast could expand biofuels' reach

Posted: 25 Jun 2021 12:56 PM PDT

Researchers found a way to reduce cellulosic feedstocks' toxicity to yeast, making it feasible to use these abundant feedstocks to produce ethanol, biodiesel, or bioplastics.

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.

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.

Scientists develop CRISPR/Cas9-based gene drive in plants

Posted: 25 Jun 2021 07:05 AM PDT

Researchers have created a CRISPR-Cas9-based gene drive designed for plants. The new technology, which allows scientists to cut and copy key genetic elements, helps scientists breed plants that defend against crop diseases and withstand the impacts of climate change.

Herbivore gut fungi found to produce unique building blocks of antibiotics

Posted: 24 Jun 2021 01:17 PM PDT

Chemical engineers have been researching the anaerobic fungi found in the guts of herbivores, which make it possible for those animals to fuel themselves with sugars and starches extracted from fibrous plants. Recent work has centered on how these powerful fungi might be used to extract value-added products from the nonedible parts of plants -- roots, stems and leaves -- that are generally considered waste products.

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.

Vegetation growth in Northern Hemisphere stunted by water constraints in warming climate

Posted: 24 Jun 2021 12:26 PM PDT

A new study of vegetation growth in the Northern Hemisphere over the past 30 years has found that vegetation is becoming increasingly water-limited as global temperatures increase, which has the potential to reduce plants' ability to absorb atmospheric CO2, increasing greenhouse gasses.
