• Austrian occupational provident funds (Betriebliche Vorsorgekassen) have increased their allocation to bonds and equities during the course of 2023, cutting exposure to real estate.

• Kim, S. Y. et al. Structural basis for cold adaptation. Sequence, biochemical properties, and crystal structure of malate dehydrogenase from a psychrophile Aquaspirillium arcticum. J. Biol. Chem. 274, 11761–11767 (1999).

• As a seasonally camouflaged species, the rock ptarmigan has brown plumage in the summer and white plumage in the winter to blend in with its surroundings. 

• When mountains are bare, this tiniest member of the grouse family blends into the scenery with mostly mottled brown-and-gray plumage. But when the snow comes, the whole ptarmigan turns the color of its tail, including the extra feathers on its legs for insulation and its feet for snowshoes – useful for a bird that only lives above treeline and prefers walking over flying.

• Lorsque la cause est plus psychologique, une consultation avec un sexologue peut être salutaire. Ce professionnel pourra conseiller l’apprentissage de techniques, comme le travail du muscle pubo-coccygien (PC), la « méthode start and stop »  ou encore la « méthode squeeze »  qui en permettant à l’homme de mieux apprivoiser ses sensations, lui permet aussi d’en trouver le contrôle.

• Investigators randomized 53 patients 2:1 to a single intravenous dose of spesolimab or placebo. The primary endpoint was the GPP Physician Global Assessment pustulation subscore (0=no visible pustules, 4=severe pustulation) at the end of 1 week, and follow-up continued to week 12. An early response assessment was chosen because of the life-threatening potential of acute and severe flares of GPP, the authors noted.

• Four-years-old Cheetah was imported from South Africa on October 29, this year and got pustulation in mouth on November 8, 2017 and after treatment given by veterinary officers, it convalesced.

• This simple rabbit spray option from Nature’s Mace combines the simplicity of a ready-to-use spray bottle with a low price, making it an affordable and easy-to-use remedy for rabbit problems. It uses a mix of garlic, putrescent egg solids, white pepper, and peppermint oil in a formula that repels using both taste and scent.

• The presence of articulated tail vertebrae in the sample enabled researchers to rule out the possibility that the feathers belonged to a prehistoric bird. Modern birds and their closest Cretaceous ancestors feature a set of fused tail vertebrae called a pygostyle that enables tail feathers to move as a single unit.

• An international research group led by Dr. Takayuki Ishii from HPSTAR and Okayama University, Institute for Planetary Materials, has precisely determined the temperature dependence of the high-pressure phase transition pressure of a mantle mineral of pyrope garnet to bridgmanite plus corundum (post-garnet transition) which may well explain the puzzling dynamics of subducting slabs and upwelling plumes observed seismically in the upper part of the lower mantle.

• Grains of forsterite (green), of pyrope (red), and of a multitude of rock types. The mix of grains was scooped up from an anthill in northwestern New Mexico. Presumably the builders of the mound, harvester ants, were not sluggards, but promptly rebuilt as to be expected from a biblical proverb.

• The sector has achieved the top position for a third quarter in a row, with eight out of 68 funds (11.8%) delivering a top quartile performance as at 31 March 2024, followed by the IA Global Mixed Bond sector in second place with six out of 71 funds (8.5%). On the other side of the spectrum, the IA £ Corporate Bond and the IA £ Strategic Bond sectors managed to avoid the bottom with one fund achieving the returns target, while all funds in the IA UK Equity Income sector failed to meet this hurdle. The percentage of funds delivering top quartile returns overall fell marginally to 2.7% ...
