Many cancer patients may need a sequential one-two punch of immunotherapies

Eurekalert - Jun 24 2021 - 00:06
New research led by scientists at La Jolla Institute for Immunology (LJI) and the University of Liverpool may explain why many cancer patients do not respond to anti-PD-1 cancer immunotherapies--also called checkpoint inhibitors.The team reports that these patients may have tumors with high numbers of T follicular regulatory (Tfr) cells.

Marmoset study identifies brain region linking actions to their outcomes

Eurekalert - Jun 24 2021 - 00:06
The 'anterior cingulate cortex' is key brain region involved in linking behaviors to their outcomes. When this region was temporarily silenced, monkeys did not change behavior even when it stopped having the expected outcome.The finding is a step towards targeted treatment of human disorders involving compulsive behavior, such as OCD and eating disorders, thought to involve impaired function in this brain region.

Research team discovers Arctic dinosaur nursery

Eurekalert - Jun 24 2021 - 00:06
Images of dinosaurs as cold-blooded creatures needing tropical temperatures could be a relic of the past. University of Alaska Fairbanks and Florida State University scientists have found that nearly all types of Arctic dinosaurs, from small bird-like animals to giant tyrannosaurs, reproduced in the region and likely remained there year-round.

Multiple dinosaur species not only lived in the Arctic, they also nested there

Eurekalert - Jun 24 2021 - 00:06
In the 1950s, researchers made the first unexpected discoveries of dinosaur remains at frigid polar latitudes. Now, researchers reporting in the journal Current Biology on June 24 have uncovered the first convincing evidence that several species of dinosaur not only lived in what's now Northern Alaska, but they also nested there.

Genome study reveals East Asian coronavirus epidemic 20,000 years ago

Eurekalert - Jun 24 2021 - 00:06
An international study has discovered a coronavirus epidemic broke out in the East Asia region more than 20,000 years ago, with traces of the outbreak evident in the genetic makeup of people from that area.

The fifth quartet: Excited neon discovery could reveal star qualities

Eurekalert - Jun 24 2021 - 00:06
Researchers at Osaka University and Kyoto University show that an excited state previously predicted to exist in neon-20 is real by using particle scattering experiments. By merging into five groups of four, the protons and neutrons in neon-20 can exist in a special condensed state. This work may help scientists understand low-density nucleon many-body systems and neutron stars.

Coincidence? I think so: researchers use phylogenetics to untangle convergent adaptation in birds

Eurekalert - Jun 24 2021 - 00:06
Researchers from Skoltech and their colleagues have shown that adaptation to similar environments hardly involves similar genomic positions when species are distantly related.It is still poorly understood to what extent adaptation to similar conditions is associated with parallel changes in the genome. The team investigated recurrent adaptations of wildlife birds' mitochondria to high altitude, migration, diving, wintering, and flight. Repeatable substitutions are rather a coincidence than adaptation, which confirms the scientific opinion that distant species 'choose' different ways of similar trait evolution.

Plant Protector: How plants strengthen their light-harvesting membranes against environmental stress

Eurekalert - Jun 24 2021 - 00:06
An international study led by Helmholtz Zentrum München has revealed the structure of a membrane-remodeling protein that builds and maintains photosynthetic membranes. These fundamental insights lay the groundwork for bioengineering efforts to strengthen plants against environmental stress, helping to sustaining human food supply and fight against climate change.

Preventing the break-in of the toxoplasmosis parasite

Eurekalert - Jun 24 2021 - 00:06
Toxoplasma gondii is an obligate intracellular parasite which, to survive, must absolutely penetrate its host's cells. Understanding how the parasite manages to enter host cells offers opportunities to develop more prevention. A team (UNIGE/UZH/PSI) has identified the key role of RON13, which is essential for the invasion process. The three-dimensional structure and the site of action of this enzyme are atypical, thus offering the possibility of designing specific inhibitors to stop the infection.

Unique christmas-tree-shaped palladium nanostructures for ascorbic acid oxidation

Eurekalert - Jun 24 2021 - 00:06
Palladium nanostructures in the shape of Christmas-tree had created using a simple electrodeposition approach on a Glassy Carbon Electrode (GCE). In alkaline conditions, the modified electrode showed eight times higher catalytic activity than the unmodified GCE for Ascorbic Acid (AA) electro-oxidation. The multiple sharp edges of the hierarchical nanostructures are account for this excellent efficiency.

Improve photosynthesis performance via photosystem II-based biomimetic assembly

Eurekalert - Jun 24 2021 - 00:06
Photosystem II (PSII) is an essential photosynthesis-involved enzyme, participating in sunlight-harvest, water splitting, oxygen release, and proton/electron generation and transfer. PSII combines with synthetic hierarchical structures via biomimetic assembly, which facilitates natural photosynthesis processes, including photocatalytic water splitting, electron transfer, and ATP synthesis, in vivo. PSII-based biomimetic assembly offers opportunities to forward semi-biohybrid research and synchronously inspire optimization of artificial light-harvest devices.
