Climate perspective depends on where the observer is — for example, unequal ocean warming and changed ocean and atmosphere dynamics 0

Western subtropical boundary currents are warming at 2 to 3 times the rate of sea surface temperatures generally — and the resulting change in ocean-atmosphere dynamics is apparently moving the currents poleward Subtropical western boundary currents flow comparatively quickly along the western sides of oceans. They move warm water from the subtropics to middle latitudes. [...]

Onset of the Little Ice Age — variously defined as somewhere between 1300-1850 — may be partially explained by significant sulfate-emitting volcanism and ice formation at its beginning 0

Women’s brains hold up slightly better to aging than men’s, according to a small study published in the journal, Neurology — and wry humor in a possibly worrisome future public health situation 0

Small numbers with significant clinical and public health implications Yesterday’s Mayo Clinic’s press release said: The study . . . reports that 296 of the 1,450 study participants developed MCI [mild cognitive impairment], an incidence rate of 6.4 percent per year overall. Among men, the incidence rate was 7.2 percent, compared with 5.7 percent per [...]

Evolutionary psychology — the “male warrior hypothesis” explains men’s aggressive and women’s fearful responses to out-groups — a paper worth reading 0

A well explained warrior hypothesis From the article’s “conclusions and implications” section: The male warrior hypothesis argues that, for men, intergroup conflict represents an opportunity to gain access to mates, territory and increased status, and this may have created selection pressures for psychological mechanisms to initiate and display acts of intergroup aggression. For women, intergroup [...]

Stanford School of Medicine’s review of electronic medical records indicated that women report up to 1 point more of pain (on a 10-point scale) than men do, across virtually all disease categories 0

A benefit of electronic records reporting The Stanford research team used electronic medical records to find out whether the genders differ in their “first” reports of pain: In this case, the scientists tapped an existing data archive that has been designed specifically for ease of research: the Stanford Translational Research Integrated Database Environment, or STRIDE. [...]

Supposedly lunar-only mineral, tranquillityite, found in Australia 0

Forgot to look in our own backyard From the abstract: Tranquillityite [Fe2+8(ZrY)2Ti3Si3O24] was first discovered in mare basalts collected during the Apollo 11 lunar mission to the Sea of Tranquillity. The mineral has since been found exclusively in returned lunar samples and lunar meteorites, with no terrestrial counterpart. We have now identified tranquillityite in six [...]

La Niña appears to be strengthening again — forecasting stormy northwest U.S. weather and repeated drought in the southwest 0

From NASA’s Jet Propulsion Laboratory website The National Aeronautics and Space Administration (NASA) posted a water temperature graphic of what La Niña’s Pacific Ocean origin looks like this year.

Increase in Arctic atmosphere water vapor and expanded October Eurasian October snow cover are credited with causing colder northern hemisphere winters (during our global warming trend) 0

Counterintuitive? — Not really But it does illustrate the difficulty of persuading global warming deniers that Actuality is not as simple-minded as we generally are. Dynamicity characterizes most natural systems. So, this finding should not be surprising: [E]vidence suggests that summer and autumn warming trends are concurrent with increases in high-latitude moisture and an increase [...]

Why would we think that only prokaryotes (bacteria and archaea) lived under the seafloor up to only 34 million years ago? — Perhaps this is an example of the pitfalls of reading science abstracts out of specialized context 0

Just because we haven’t seen it before does not mean that “it” wasn’t there, especially when “it” was everywhere else at the time Here’s the puzzle. From the abstract: The deep biosphere of subseafloor basalts is thought to consist of mainly prokaryotes (bacteria and archaea). Here we report fossilized filamentous microorganisms from subseafloor basalts interpreted [...]

Inflatable abdominal tourniquet may save lives of wounded troops — who have been hit below their body armor, thereby sustaining damage to the abdominal aorta and/or great leg vessels 0

Building from previous knowledge Georgia Health Sciences University reported yesterday that two emergency medicine physicians with wartime experience came up with this inflatable abdominal tourniquet. The device has been successfully tested for durations up to one hour on pigs. Human testing has been shorter periods, apparently solely to see whether the pressure generated was enough [...]
