Mother's breasts may protect a newborn from the cold—a new perspective on breast evolution

Humans differ from other primates due to their relatively large, permanent breasts, and their development has so far not been conclusively explained. According to a study conducted at the University of Oulu, Finland, the surface temperature of the breasts combined with their size and shape may help a newborn maintain body temperature.

Behavioural #thermoregulation is vital for #reptiles and may involve cognition! A new FunMorph study led by Ioanna Gavriilidi tested whether better spatial cognition is linked to more efficient thermoregulatory behaviour, accounting for personality 🦎

Using common wall lizards in a realistic, thermally heterogeneous environment, higher cognition scores were linked to better exploitation of thermal variation, but not to more accurate thermoregulation.

Some #insects support passive #breathing via tracheae through #active #respiratorymovements, nsmed #convectiveventilation. Muscle contractions cause motions that e.g. dilate the #spiracles, allowing more efficient #gasexchange. The same time, the process also serves #thermoregulation. My example, the #robberfly #Tolmerus #cingulatus, demonstrates this #behavior.

📚 Tiere nutzen vielfältige Strategien zur Hitzeregulation.

• Kühlung durch Verdunstung (z.B. Hecheln).
• Anpassung des Verhaltens (z.B. Schatten suchen).
• Spezifische anatomische Merkmale (z.B. große Ohren).

Überraschende Strategien, wie Tiere mit Hitze umgehen

Viele Tiere leben in heißen Umwelten. Einige ihrer Tricks zur Thermoregulation ähneln Strategien von uns Menschen - andere eher nicht. Sie wirken fast schon bizarr.

Deconninck et al. provides a refreshed view of how plasticity in temperature preference can inform us about the thermoregulatory strategies of ectotherms. An all-new framework that they apply to Drosophila melanogaster.

The claim is circulating that antidepressants can cause overheating and dehydration. This is a genuine public health message, but it's not so simple: diuretics, beta blockers, ACE inhibitors, antipsychotics, and some antihistamines may also interact badly with hot weather.
https://www.nytimes.com/2024/06/15/well/live/heat-weather-medication-safety.html (excerpt in a reply)

There's even doubt about antidepressants having this effect. A recent paper in eClinicalMedicine looked at all the studies they could find and concluded that there wasn't evidence of antidepressants causing overheating in hot weather - though some other medicines do.

"Current evidence supports strong anticholinergics, non-selective beta-blockers, adrenaline, and anti-Parkinson’s agents impairing thermoregulation during heat stress ... physicians should interpret with caution conventional public health messaging related to the thermoregulatory effects of some drugs (e.g., antidepressants) during hot weather."

Remembering the cold: scientists discover how memories control metabolism

New multidisciplinary research led by Prof. Tomás Ryan from Trinity College Dublin shows that the brain forms memories of cold experiences and uses them to control our metabolism. This newly published study is the first to show that cold memories form in the brain – and map out how they subsequently drive thermoregulation. The discovery may have important applications in therapies designed to treat a range of disorders – from obesity to cancer – in which thermoregulation and metabolism (or a lack of control in this area) plays a role, as well as opening the door to more fundamental research, which could help us better understand how memories impact our behaviour and emotions.

The High Energetic Costs Of Changing Colors In Octopus
