Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

9. In 1826 presenteert Audubon in Edinburgh voor “The
Royal Society” een onderzoek naar het reukvermogen
van de Turkey Vulture c.q. Kalkoengier
10. roodkopgier of kalkoengier
Cathartes aura
Familie Cathartidae
NIET verwant aan de Europese gieren
Audubon twijfelde aan de volksopvatting dat Kalkoengieren kadavers
vinden met behulp van hun reukvermogen.
11. “Een verslag van de leefgewoonten van de kalkoengier (Vultur aura),
met het accent op het ontkrachten van de wijdverbreide opvatting over
zijn uitzonderlijk scherpe reukzin”
In 1826 presenteert Audubon in Edinburgh een onderzoek
naar het reukvermogen van de Turkey Vulture c.q.
Kalkoengier
12. Verstopt kadavers (lekker rottend en stinkend) van
diverse grote dieren
Keek of de gieren die wisten te vinden
Dat was nooit het geval
Conclusie: Kalkoengieren vinden kadavers alleen
visueel
13. Resultaten gepubliceerd in Nature in 1826, worden
breed geloofd, m.n. door veel eminente ornithologen, al
was er ook tegenkamp.
Tot in 20e eeuw worden experimenten uitgevoerd om de
conclusie van Audubon te steunen, zoals:
John Bachman: herhaalt de proef van Audubon in
aanwezigheid van “getuigen”
Alexander Hill publiceerde in 1905 in Nature een proef
met tamme kalkoen.
Krijgt 2 schaaltjes met voedsel, waarvan één met stank
onder voedsel; dit werd toch gegeten.
Concludeert dat kalkoenen niet kunnen ruiken.
14. Toch na publicatie van Audubon veel tegengeluiden
Richard Owen in 1837: onderzoekt
anatomie van kalkoengier en van
reukorgaan
16. “dus” ???????
bij een vogel is de geurzin knobbel
veel kleiner dan optische knobbel.
Conclusie was “dus” is reukzin
inferieur
17. Uit anatomisch onderzoek bleek:
•vogel heeft neusholte
•neusholte voorzien van weefsel met “geursensoren”
•deze zijn via zenuwbanen verbonden met gedeelte van de
hersenen
Toch is lang consensus:
• vogel kan slecht ruiken
• hooguit enkele uitzonderingen
Argumentaties:
• “reukzinknobbel” veel kleiner dan hersendeel gericht op
het zien, zien is veel en veel belangrijker
• Reukzin onderdelen zijn restanten van (reptielen)
voorouders, zijn gedegenereerd
21. Toch zijn er onderzoekers die “de standaard uitleg” niet
accepteren en gericht onderzoek gaan doen.

22. Betsy G. Bang
1912-2003
Illustrator medische en wetenschappelijk artikelen.
Getrouwd met Frederik Bang, onderzoeker van o.m. infecties en
ademhalingsproblemen bij (boerderij)vogels
Betsy maakte de illustraties voor zijn publicaties, w.o. de
neusholten
waarom zo complex en gevarieerd als het geen functie heeft ?
Begon rond 1960 eigen anatomisch onderzoek
Anatomical evidence for
olfactory function in some

27. Lucht wordt aangezogen door twee externe neusgaten,
spleten in de bovenkant van de snavel
Lucht doorstroomt aantal kamers:
Verwarmen en ontvochtigen
neusschelpen
Neuschelpen opgerolde massa kraakbeen bekleed met laag
weefsel met cellen die geuren waarnemen
Bij al deze drie vogels neusholte groot met veel weefsel
“door dat artikel kon je onmogelijk blijven
volhouden dat vogels niet kunnen ruiken”
32. Procellariiformes / Buissnaveligen: 29
Podidipediiformes / Futen: 24,5
Caprimulgiformes / nachtzwaluwachtigen: 24,5
Per familie de gemiddelde verhouding van de diameters van de
“geurzinknobbel” versus de hersenen X in %
35. Conclusie Bang en Cobb (1968) uit relatieve afmeting van
“reukzinknobbel”:
reukvermogen is
• belangrijk bij Kiwi, Buissnaveligen en zeker één soort Gieren
• goed bij veel soorten (watervogels, moerasbewoners)
• bij andere soorten relatief onbelangrijk
36. Veel verder anatomisch onderzoek in
tachtiger jaren: al die details moeten ergens
goed voor zijn
maar hoe zit het nu echt met het
reukvermogen ???
37. Toch onderzoekers die hier geen genoegen mee namen

38.
39. Kenneth Stager:
• eigen ervaringen met Kalkoengieren
• verwondering over standpunt “de ornithologie”:
vogels hebben geen reukzin, ondanks tegengeluiden
41. Kenneth Sager start daarom zeer uitvoerig
onderzoek naar reukzin bij Kalkoengieren
42.
43. Experiment herhaald op meerdere dagen en andere locaties:
ca. 20 gevallen met duidelijke reactie
Alternatieve opzet experiment met karkas verstopt in kartonnen
dozen. Verschillende soorten aas, meerdere dagen, verschillende
locaties: veel gevallen met duidelijke reactie
Als karkas opgezet hert
neergelegd: geen reactie van
overvliegende kalkoengieren
Als karkas opgezet hert vervangen
door echt karkas: direct reactie van
overvliegende kalkoengieren
48. Betsy: relatief grote reukzinknobbel bij de Buissnaveligen: 29

This experiment was conducted between 8 July and 25 July
1996 at the Bowdoin College Biological Research Station,
Kent Island, New Brunswick (44°35¢ N, 66°45¢ W).
Experiments were conducted on clear nights between 23.00·h
and 03.30·h. Wind speeds were negligible (<5·knots) during
experimental trials; thus, wind directions were not recorded.
Experimental set-up
We mounted a small (10·cm´15·cm) plywood platform on
a pole approximately 1.5·m high over an open field within 10·m
of an active breeding colony (near ‘petrel path’). A small
amount (5·ml) of test odor [DMS (100·mmol·l–1), or
control solution (plain water)] was placed in a small (25·mm)
Petri dish and positioned on the platform. An observer,
positioned 25·m crosswind from the platform, recorded activity
of each bird as it approached the platform. Observations were
assisted by a night vision scope (Model MKF28; Startron Mfg.,
Freeport, PA, USA) and recorded into a dictaphone

Editor's Notes
John James Audubon (April 26, 1785 – January 27, 1851), born Jean-Jacques Audubon, was an American ornithologist, naturalist, and painter. He was notable for his expansive studies to document all types of American birds and for his detailed illustrations that depicted the birds in their natural habitats. His major work, a color-plate book entitled The Birds of America (1827–1839), is considered one of the finest ornithological works ever completed. Audubon identified 25 new species.
