FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

A Laser Polar Motion Experiment [PDF]
Symposium - International Astronomical Union, 1972 SummaryFor three months in 1970, NASA, Goddard Space Flight Center conducted an experiment to try and detect the motion of the Earth's pole of rotation by laser ranging to an Earth satellite. Two laser tracking stations were used, one at Goddard Space Flight Center and one near Seneca in New York State, 408 km away and on the same meridian as the ...

Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells
FEBS Open Bio, EarlyView.To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

FEBS Open Bio, EarlyView.TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Trichinella sp. in polar bears from Svalbard, in relation to hide length and age
, 2010 Diaphragm and masseter muscles from 376 polar bears ((irsur maririmus), 252 ringed seals (Phocn hispida), 84 bearded seals (Erignarhus barbarus), and 77 arctic foxes (Alopex lagopus) from Svalbard were examined for Trichinelln.

FEBS Open Bio, EarlyView.The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Polar bears killed in Svalbard 1987–1992
, 1993 A total of 26 polar bears have been killed in Svalbard since January 1987. Fifteen of these cases were self defense, four precautionary measures, six acts of mercy and one unknown.

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy
FEBS Open Bio, EarlyView.This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...

Reducing filter effects in GRACE-derived polar motion excitations
Earth, Planets and Space, 2019 Polar motion is caused by mass redistribution and motion within the Earth system. The GRACE (Gravity Recovery and Climate Experiment) satellite mission observed variations of the Earth’s gravity field which are caused by mass redistribution.

The interplay of global and polar regimes
, 1999 The growing salience of interactions between the functionally broad but geographically narrow regimes for the polar regions and the geographically broad but functionally specific regimes emerging to deal with global environmental changes directs ...
