Protein molecules in mitochondria clearly assigned for the first time

Mitochondria are key components of our cells. Cell respiration and control of many metabolic and signaling processes take place within them. In order for the biochemical reactions to take place flawlessly, complex interactions between specialized protein molecules are required. Yet up to now, it wasn't known how many of the proteins in cells are also actual components of the mitochondria because...

New study shows benefits of ammonium for pine root growth

In ecological terms, coniferous formations represent the biggest terrestrial carbon sink, they play an essential part in the pollination of the ecosystems where they grow and, moreover, help improve agricultural production. At the same time, from an economic point of view, they are the main source of raw material for wood industries.

The long transition to environmental sustainability is already underway

While the transition from today's service and brain-based economy to an environmentally sustainable economy will take decades to complete, the change has already begun. The time scale of the change is important to understand. I base my sense of the time scale on a change process that I, along with many residents of New York City, unknowingly lived through. It was New York's painful evolution from...

Celebrated barley came from a single plant

The 200-year-old malting barley variety 'Chevalier' was for a long time world-leading in beer brewing and is thought to have originated from a single plant. In a new study, Swedish researchers from the universities of Linköping and Stockholm have investigated this claim. They have analyzed seed samples that are older than 150 years using molecular genetic methods. The results give a revealing...

Rivers speeding up Arctic ice melt at alarming rate

Freshwater flowing into the Arctic Ocean from the continent is thought to exacerbate Arctic amplification, but the extent of its impact isn't fully understood. New research measures how the flow of the Yenisei River -- the largest freshwater river that flows into the Arctic Ocean -- has changed over the last few hundred years, and describes the impact freshwater has had on the Arctic.

Boosting T cells improves survival in mice with glioblastoma

A new study shows that treatment with an immune-boosting protein called interleukin 7 (IL-7) in combination with radiation improves survival in mice with glioblastoma. The study in mice suggests promise for a phase 1/2 clinical trial that is investigating a long-acting type of IL-7 in patients with glioblastoma.

Additional antibodies may protect against COVID, study shows

When we talk about antibodies against COVID-19, we tend to mean the so-called neutralizing antibodies, that offer protection by blocking the virus from invading our cells. Now, a new study has revealed that non-neutralizing antibodies may also be important in providing protection against COVID.
