50 years of spotting southern right whales off Great Australian Bight.
From Western Australia's capital to South Australia's
far west coast, scientists have collated 50 years' worth of data on the southern right whale to track changes to breeding cycles.
Gordijn open, ruit beslagen, een plasje op de vensterbank. Je pakt een doekje en denkt dat het aan de ramen ligt. Meestal is het andersom: de ruit is alleen de plek waar zichtbaar wordt wat er in de lucht van je huis hangt. En dat zegt meer over je ventilatie dan over je glas.
Wat er eigenlijk gebeurt
Warme lucht kan veel vocht bevatten. Komt die lucht tegen een koud oppervlak, dan koelt hij af en moet hij water kwijt. Dat zijn de druppels op je raam. Een gemiddeld gezin produceert met douchen, koken, wassen en schoonmaken zo'n tien liter vocht per dag. Dat moet ergens heen. Schiet de ventilatie tekort, dan blijft het hangen en slaat het neer op de koudste plekken in huis: ramen, kozijnen en muren.
Binnen, buiten of ertussen
Waar de condens zit, vertelt veel:
- Binnenkant: de lucht in huis is te vochtig of wordt te weinig ververst. Bij enkel glas is de ruit bovendien zo koud dat er snel iets neerslaat.
- Buitenkant: goed nieuws. Dat zie je bij goed isolerend glas, vooral op koude ochtenden in het voor- en najaar. Het glas houdt de warmte binnen, dus blijft de buitenkant koud.
- Tussen de glasplaten: de afdichting van je dubbele ruit is lek. Droogwrijven helpt dan niet; de ruit moet worden vervangen.
Condens aan de buitenkant is geen fout, maar het bewijs dat je glas zijn werk doet.
Waarom je het niet moet wegpoetsen
Even een beslagen ruit na het douchen hoeft geen probleem te zijn, als je daarna goed ventileert. Wordt het een dagelijks patroon, dan ligt schimmel op de loer. Vocht en schimmel in huis vergroten de kans op luchtwegklachten en kunnen astma verergeren. Die zwarte rand rond het kozijn is dus meer dan een schoonheidsfoutje.
Het risico groeit juist in huizen waar de thermostaat een paar graden omlaag gaat en ramen en roosters zoveel mogelijk dicht blijven om energie te besparen. Weinig ventilatie in combinatie met een lage temperatuur is precies de mix waarin schimmel gedijt.
Wie de roosters dichtplakt om stookkosten te sparen, betaalt soms met een natte vensterbank.
Zo pak je het aan
- Laat ventilatieroosters en klepraampjes dag en nacht open, ook in de winter.
- Zet mechanische ventilatie nooit uit. Kies de hoogste stand tijdens koken en douchen en laat hem daarna nadraaien.
- Hangt de was binnen te drogen of zijn er veel mensen in huis? Ook dan de hoogste stand.
- Kook met de deksel op de pan en zet de afzuigkap aan.
- Laat het huis 's nachts niet verder afkoelen dan 15 graden.
- Twijfel je? Een eenvoudige vochtmeter laat zien hoe vochtig het binnen is. Een luchtvochtigheid tussen 40 en 60 procent geldt als goed.
Huurder met schimmel? Ontstaat er ondanks goed ventileren toch vocht of schimmel door de staat van de woning, meld het dan schriftelijk bij je verhuurder en geef zes weken de tijd. Gebeurt er niets bij een sociale huur- of middenhuurwoning, dan kun je de Huurcommissie inschakelen. Die kan bij ernstige gebreken de huur tijdelijk verlagen, maar de verhuurder niet dwingen tot herstel.
Het droogwrijven van de ruit voelt als opruimen, maar je veegt alleen het symptoom weg. Het echte werk zit in de roosters.

While I suspect my husband and some of my friends would make excellent Traitors, my poker face is worse than Richard E Grant’s – as I learned when I played the game
Yes, yes, it’s achieved the impossible: brought back watercooler terrestrial TV, united the UK’s viewing habits, healed our divided nation. But more importantly, The Celebrity Traitors has given us a lens through which to look at life. Currently, the only conversation worth having is what you think you, whoever you’re talking to, and all your friends and family members would be like as contestants on the show. It’s a quick-smart way to evaluate society, a new shorthand. Describe a stranger as having “Faithful energy” and there are surely about two humans on these islands who wouldn’t understand exactly what you mean.
Can you handle the truth, though? It was a poignant moment on my journey of self-acceptance when I was forced to acknowledge that I’d be terrible as both a Traitor and a Faithful. However, confronted with most of the people who know me best being absolutely certain, laughing through tears at the idea of any other outcome, there was no getting away from it. The accusation was levelled that I would jump out of my skin and squeal if my shoulder was touched at the initial roundtable, meaning my Traitorhood would be over before it had begun, which was futile to deny. I suggested I might try to make the squeal seem like a double bluff – which was met with further amusement. Apparently my poker face is even less convincing than I thought. I’d make Richard E Grant look like a slick covert operator.

People living in one of Amsterdam’s most exclusive neighbourhoods have taken the city to court for licensing a chip shop that has gone viral on TikTok.
On busy days, the queue for Fabel Friet on Runstraat stretches across a bridge on the Keizersgracht – one of Amsterdam’s three main canals – a court was told last week. The narrow street itself is crowded by tourists waiting for their orders seven days a week. And loitering with intent – on parked cars, on the street itself, and on steps and porches – gulls wait to swoop.

Main Beach, the largest and most iconic beach on North Stradbroke Island (Minjerribah, stretches for an impressive 32 kilometres from Point Lookout (Mulumba) to the southern tip of the island. This spectacular stretch of coastline is perfect for swimming, surfing and beach walks, and beach driving (with a vehicle access permit.
As the prevailing wave pattern on the Nsw and Queensland coast is from the Tasman Sea, the waves in the surf zone approach the coast at an angle rsulting in the sustaining of a northward longshore drift of sand. This longshore flow of sand has been dammed by rocky outcrops, or spurs of the mainland that reach the coast. As the sand flows around the headland then, it continues its journey northward, until the flow ultimately reaches a changein direction of the continental shelf edge, and there the sand flows off the continental edge to accumulate in the deep water - beyond Sandy Cape at the northern extremity of Kgari/Fraser Island. Not all the sand fed into the longshore drift by the rivers reaches the extremiy just identified, for much is trapped in larg bays such as Hervey Bay, or blown from the beach into the backing vegetation accumulating as dunes, or beyond into backing swamps , forests and lakes.

While most magnets have two poles (north and south, or positive and negative), recent advances in quantum mechanics have revealed an "octupolar order," writes Phys.org, where a pattern of particles in a crystalline structure "behaves as if it has eight magnetic poles rather than the familiar two."
Now, a team led by quantum physicists at the University of Toronto has established a new method for observing quantum magnetic states using light to probe the atomic vibrations produced as electrons spin. The work is a critical first step toward harnessing multipolar magnetism for practical technologies, including next-generation data storage and computing devices.
"We identified new signatures of a hidden type of magnetic state which cannot be detected using ordinary probes," says Arun Paramekanti, a professor in the Department of Physics and the Center for Quantum Information & Quantum Control in the Faculty of Arts & Science at the University of Toronto, and senior author of a study published in Physical Review Letters that describes the findings.
"Our research opens up the possibility for using higher-order magnets in several applications including controllable read-write memory elements found in everyday computers...."
By directing a special type of rotating light at magnetic materials, the team observed a clear optical fingerprint of the otherwise hidden magnetic order.... The findings offer a new tool for uncovering and manipulating previously inaccessible forms of magnetism, opening new avenues for quantum technology development.

"We will not add facial recognition to our devices," Flock CEO Garrett Langley said in a recent video. But other, third-party companies are telling cops that they are willing to add facial recognition to data gathered by Flock cameras in order to "close that gap." A company called VIDIZMO is advertising the capability to export footage from FlockOS to its own platforms that do facial recognition, behavior prediction, and racial and gender analysis on live camera feeds. VIDIZMO is a several decades-old video analysis and database company that has started offering facial recognition technology to cops within the last six months. In a May email to Johnson City, Tennessee, deputy police chief Michael Adams, a salesperson from VIDIZMO wrote that the company's product could do facial recognition on both Flock and Axon [body-worn camera] data in "one searchable platform...."
VIDIZMO's CEO, Nadeem Khan, told 404 Media on a video call that the company has not yet started running facial recognition tech on footage from Flock cameras, and that it has not actually built the specific tool that would export data from Flock's system to its own platform (though the company advertises this capability online, and the company already sells other facial recognition products). But Khan said VIDIZMO "would love to do the integration," and that he believes facial recognition "is the way the world is going, the way the world will have to be," and that he thinks Flock should offer the capability itself in a way that "balances privacy, security, and the freedom that we enjoy in this country."
The article notes that VIDIZMO says on its website, "You can identify individuals from seven races: White, Black, Indian, East Asian, Southeast Asian, Middle Eastern, and Latino Hispanic." VIDIZMO adds that stores or cities can also then do "demographic analysis" for marketing purposes by determining the races or ages of people showing up....
