News roundup, 21 Aug 2025

- Winnipeg's Granite Curling Club is appealing the City of Winnipeg's decision to develop a city-owned surface parking lot into affordable housing to the Manitoba Municipal Board. The building, if built, will be a mixed income facility, with 55 market rent units and 56 at various reduced rates. The club's management fear that reducing the amount of available parking will devastate them; perhaps they think that curlers aren't proper athletes and would thus balk at having to walk a couple of hundred metres. 

- The CEO of Target, Brian Cornell, is stepping down after several bad years for the company. This year has been especially bad; one factor seems to be that the company had jumped on the anti-DEI bandwagon despite previously having taken DEI policies more seriously than most chains. As a result, the chain's customers, who have tended to be politically more progressive on average than those of other retailers due to those former policies, found themselves with a lot less reason to choose them over another company.

- China's carbon emissions in the first half of this year have declined compared to the year before. US emissions, however, have increased in the same time period.

- A Chinese company claims to have developed a robot with an artificial womb. The product, billed as "a pregnancy alternative for those who wish to avoid the burdens of human gestation", is supposed to come out next year at a cost of only 100,000 yuan (around $US 13,900).

- A daycare in Brantford, Ontario was closed for several days after a dead bat found on the premises tested positive for rabies. A case was also detected in a bat in Centre Wellington; one person is undergoing precautionary treatment due to the possibility of exposure to the deadly disease. 

- A man in Kawartha Lakes, Ontario has been charged with aggravated assault and assault with a weapon after attacking a home invader. Given that the intruder has also been charged with possession of a weapon for dangerous purposes, I do have to wonder why the police didn't think the resident's response was "proportionate to the threat faced" as required by law, though the details definitely matter in a case like this (if, for instance, the intruder was attacked from behind while fleeing, or beaten after he was no longer a threat, charging the resident might be legitimate). Rightwing populists aren't waiting for the facts to come in before shooting their mouths off, of course.

- The family of a man who died after a suicidal jumper landed on the car in which he was riding are suing the City of Toronto for failing to install suicide barriers on the Leaside Bridge, from which the other man jumped.

- The US Supreme Court has refused to preemptively block new EPA rules concerning methane and mercury, asking for the plaintiffs to file their claims in U.S. Court of Appeals for the District of Columbia first. This is somewhat promising, though if the case does land on their desks after going through the lower court there is no guarantee that they will uphold the rules.

- While natural gas has been promoted as a somewhat cleaner alternative to coal, a recent study has concluded that the climate impact of leakage during the transportation of liquefied natural gas is actually worse, largely due to the inevitable leakage of methane (the main constituent of the fuel).

- Bubba Pollock, the man who posted a selfie with a woman's dying father in order to harass her after getting into an online debate with her, was sentenced to 60 days in jail. He has a history of other criminal activity, including bribing homeless people to steal Pride flags and to pull fire alarms in libraries where drag-related events were being held. This is on top of more mundane (but equally disturbing) convictions such as sharing intimate images without consent.

- Physicians in Manitoba are getting tired of having to waste time signing sick notes demanded by employers. The province is one of three that have no restrictions as to when an employer can demand one; Doctors Manitoba is calling for this to be changed, saying that this can open up more time for actually useful patient visits.

- The chances of averting a healthcare strike in Manitoba are quickly fading; the unions say they are nowhere near a deal as tomorrow's strike deadline approaches.

- A child in the Brantford area has died of rabies, after having apparently contracted the disease from a bat while on vacation in Timiskaming District. Disconcertingly, there was no visible sign of a bite from the animal; experts are recommending that anyone who has been in contact with bats to get immediate medical attention.

Isn't nature wonderful?

This story is a few years old, but I'd never come across it before, and it's downright fascinating:

A parasitic worm that makes the grasshopper it invades jump into water and commit suicide does so by chemically influencing its brain, a study of the insects' proteins reveal.

The parasitic Nematomorph hairworm (Spinochordodes tellinii) develops inside land-dwelling grasshoppers and crickets until the time comes for the worm to transform into an aquatic adult. Somehow mature hairworms brainwash their hosts into behaving in way they never usually would - causing them to seek out and plunge into water.

Once in the water the mature hairworms - which are three to four times longer that their hosts when extended - emerge and swim away to find a mate, leaving their host dead or dying in the water. David Biron, one of the study team at IRD in Montpellier, France, notes that other parasites can also manipulate their hosts' behaviour: "'Enslaver' fungi make their insect hosts die perched in a position that favours the dispersal of spores by the wind, for example."

But the "mechanisms underlying this intriguing parasitic strategy remain poorly understood, generally", he says.

From the New Scientist. We might feel comforted in the fact that mammals' brains are a lot bigger than those of insects, so surely our behaviour couldn't be influenced by a parasite or pathogen. Or could it?
