AIN'T NOBODY GOT TIME FOR THAT
Since we’re already seeing holiday decorations go up in our favorite stores, we better get some holiday hairstyle ideas up on your faaavorite beauty website! Not sure about you guys but I often find myself working until the very last second, then rushing home, then rushing out with a bottle of bubbly in one hand and red lipstick in the other. With so many fancy festivities toward the end of the year, it’s always a good idea to have some 10 minute hairstyles on tap. This one is definitely a TBD favorite. The style is similar to my signature “Fun Bun” tutorial you might remember from a couple years ago. The main difference is, you can tease this one to make it as voluminous as you’d like. This updo reminds me of one of those super-famous//super-massive//super-chic SJP buns! Alright… here’s how you take your hair from a work bun to a party bun…
You will need: a comb, bobby pins (large + small), a small clear elastic, travel sized hairspray that fits in your purse if you plan on doing this after work without going home.
There it is! The big ol’ party bun. Hope you wear it with your favorite sparkly get up this holiday season. Last week we saw so many of your gorgeous Rodarte-inspired braids! If you try this updo, don’t forget to tag us in your instagram @thebeautydept! Can’t wait to see what you accessorize with!
Autonomia porque resolvemos nossas coisas sozinhos. Pagamos nossas contas sozinhos, moramos sozinhos, trabalhamos sozinhos, decidimos sozinhos. Mas trabalhamos em equipes, temos que consultar um chefe, arrumamos namoradas, passamos finais de semana na casa dos pais. Pedimos opinião dos amigos, consultamos resenhas na internet, temos happy hours com galera, nos sentimos sozinhos, trocamos piadas horríveis em grupos do whatsapp. Mandamos mensagens longas demais quando bebemos, vemos filmes que nos fazem lembrar de pessoas, queremos dividir com os outros aquela música. Escrevemos pra alcançar pessoas, viajamos pra encontrar pessoas, dormimos encostados em pessoas. Sentimos falta de outras pessoas de manhã.
Estabilidade porque temos coisas certas, coisas organizadas, coisas estáveis. Temos um namoro firme, um emprego estável, uma vida organizada. Mas ela pode descobrir que gosta de outro cara, vocês podem se cansar de estar juntos, você pode se apaixonar pela voz da secretária eletrônica como no trailer de um filme. Você pode ser demitido, a empresa pode passar por uma fusão, existe o downsizing, existe o saco cheio, existe a vontade de largar essa merda toda que bate todo dia ali pelo meio da tarde, quando você lembra que seu sonho era fazer um musical de terror sobre fantoches. Existe a crise econômica, a crise dos trinta, a crise de meia idade, a crise existencial, existe o el niño. Existe a gravidez fora dos planos, existem os pais que se separam, existe o irmão que viaja, existe a proposta inesperada, existe a chance de ir pra muito longe ganhar muito menos fazendo algo que você goste muito mais.
Maturidade porque se espera que ao crescer a gente, bem, a gente cresça. Decisões sérias, escolhas ponderadas, atitudes adultas. Mas enchemos a casa de memorabília, gastamos com férias o dinheiro da casa, compramos o carro que é mais bonito, escolhemos destinos de viagem baseados num filme das gêmeas Olsen que vimos na sessão da tarde mas não admitimos isso em público e dizemos que é por causa dos restaurantes. Batemos boca no trabalho por causa de besteira, discutimos no trânsito por causa de besteira, terminamos relacionamentos por causa de besteira, dizemos que os outros só se preocupam com besteira. Reclamamos dos outros na internet, usamos a página de comentários, mentimos pro cara do censo, compramos coisas do polishop porque agora temos dinheiro pra isso. Temos sabres de luz do ladoda vodka nas prateleiras da sala.
Então acho que, sendo a vida adulta mais um conceito vago do que uma meta, sendo o amadurecimento mais um processo sem fim do que um estado alcançável, sendo a casa dos 30 mais um marco simbólico e uma autorização implícita pra reclamar de dores nas costas sempre que conveniente do que algum deadline social onde se torna inaceitável atender o próprio telefone fixo se passando por outra pessoa pra não resolver um assunto, nós, como um todo, não estamos nos saindo tão mal assim.
MAS GENTE HAHAHAHAHAHAHAHAHAHAAHAHA
There are some medical case studies that are so fantastical that it’s pretty hard to believe that they aren’t urban legends. Our favorite example is the Conception by Oral Sex, but this is a really close second.
Accidental condom inhalation.
“A 27-year-old lady presented with persistent cough, sputum and fever for the preceding six months. In spite of trials with antibiotics and anti-tuberculosis treatment for the preceeding four months, her symptoms did not improve. A subsequent chest radiograph showed non-homogeneous collapse-consolidation of right upper lobe. Videobronchoscopy revealed an inverted bag like structure in right upper lobe bronchus and rigid bronchoscopic removal with biopsy forceps confirmed the presence of a condom. Detailed retrospective history also confirmed accidental inhalation of the condom during fellatio.”

Você sabia que a duração do mijo dos mamíferos é basicamente a mesma? Independente do tamanho? Então. Que coisa, né.
We don’t usually post pre-prints, but we couldn’t resist this one. A group of physicists from Georgia Tech went to Zoo Atlanta to watch animals urinating. To their surprise, they discovered that regardless of size, most mammals urinate for about the same amount of time (21 seconds), despite large differences in bladder volume, a phenomenon they term the “Law of Urination”. They explain this law using physics, and illustrate their explanation with an amazing video (below) that is absolutely a must-see.
Law of Urination: all mammals empty their bladders over the same duration
“The urinary system evolved to eject fluids from the body quickly and efficiently. Despite a long history of successful urology treatments in humans and animals, the physics of urination has received comparatively little attention. In this combined experimental and theoretical investigation, we elucidate the hydrodynamics of urination across five orders of magnitude in animal mass, from mice to elephants. Using high-speed fluid dynamics videos and flow-rate measurement at Zoo Atlanta, we discover the “Law of Urination”, which states animals empty their bladders over nearly constant duration of average 21 seconds (standard deviation 13 seconds), despite a difference in bladder volume from 100 mL to 100 L. This feat is made possible by the increasing urethra length of large animals which amplifies gravitational force and flow rate. We also demonstrate the challenges faced by the urinary system for rodents and other small mammals for which urine flow is limited to single drops. Our findings reveal the urethra evolved as a flow-enhancing device, enabling the urinary system to be scaled up without compromising its function. This study may help in the diagnosis of urinary problems in animals and in inspiring the design of scalable hydrodynamic systems based on those in nature.”

Are humans that different from gas particles? Not according to these physicists. They carefully studied online videos of mosh pits at heavy metal concerts, measured the motions of each participant, and then determined how well their data fit simplified models of particle physics. Amazingly, the best fit for mosh pits was to the Maxwell–Boltzmann distribution, which “describes particle speeds in gases, where the particles move freely without interacting with one another, except for very brief elastic collisions in which they may exchange momentum and kinetic energy, but do not change their respective states of intramolecular excitation” Sounds like a mosh pit to me!
Collective Motion of Humans in Mosh and Circle Pits at Heavy Metal Concerts
“Human collective behavior can vary from calm to panicked depending on social context. Using videos publicly available online, we study the highly energized collective motion of attendees at heavy metal concerts. We find these extreme social gatherings generate similarly extreme behaviors: a disordered gaslike state called a mosh pit and an ordered vortexlike state called a circle pit. Both phenomena are reproduced in flocking simulations demonstrating that human collective behavior is consistent with the predictions of simplified models.”

(It’s Red Hot Science Week here at Seriously, Science? All week long we will be featuring science that focuses on the color red.)
If you’re wondering whether scientists have a sense of humor, look no further. This Norwegian ecologist decided to diagnose Rudolph the Red-Nosed Reindeer, concluding that the famous reindeer was suffering from a parasitic infection of his respiratory system (LOL!) Maybe that’s why the other reindeer never let him join in their games?
Epidemiology of reindeer parasites.
“Every Christmas we sing about Rudolph the red-nosed Reindeer, but do we give much thought to why his nose is red? The general consensus is that Rudolf has caught a cold, but as far as I know no proper diagnosis has been made of his abnormal condition. I think that, rather than having a cold, Rudolf is suffering from a parasitic infection of his respiratory system. To some this may seem a bit far-fetched as one would not expect an animal living with Santa Claus at the North Pole to be plagued by parasites, but I shall show otherwise.”

It’s well known that men have higher rates of heart disease than women. But is there a difference between “girlier” and “manlier” men when it comes to heart disease death rates? This study surveyed over 1500 men and women to determine whether femininity vs. masculinity was associated with risk of death from coronary heart disease. They found that men identified as “feminine” or “expressive” had a lower risk of death from heart disease than those who had a more stereotypically masculine self-image, suggesting that differences in heart disease death rates between men and women might not solely be physiological. Maybe the stereotypically masculine men are just too stubborn to go to the doctor?
Decreased risk of death from coronary heart disease amongst men with higher ‘femininity’ scores: a general population cohort study.
At all ages men have higher rates of coronary heart disease (CHD) than women, although similar proportions of men and women eventually die of CHD. Gender differences in CHD incidence and mortality are often explained in relation to biological (hormonal) and behavioural risk factors (e.g. smoking), but psychological factors and broader social constructions of gender are rarely considered.
To examine the relationship between measures of gender role orientation at baseline in 1988 and mortality from CHD over 17 years (to June 2005).
Prospective cohort study linked to national mortality reporting.
Socially varied, mainly urban area centred on city of Glasgow in West Central Scotland, UK.
In total, 1551 participants (704 men and 847 women) aged 55 years took part in detailed interviews with nurses trained in survey methods in 1988. These included a wide range of measures of physical development and functioning, self reported health and health behaviour, personal and social circumstances and a measure of gender role orientation (yielding scores for ‘masculinity’ and ‘femininity’).
MAIN OUTCOME MEASURES:
Mortality from CHD up to June 2005 (88 CHD deaths in men; 41 CHD deaths in women).
After adjusting for smoking, binge drinking, body mass index, systolic blood pressure, household income and psychological well-being, higher ‘femininity’ scores in men were associated with a lower risk of CHD death (hazards ratio per unit increase in ‘femininity’ score 0.65, 95% CIs 0.48-0.87, P = 0.004). No such relationship was observed amongst women. ‘Masculinity’ scores were unrelated to CHD mortality in either men or women.
These results suggest that social constructions of gender influence the risk of ill health, here death from CHD. Men who are less able to identify themselves with characteristics identified as ‘feminine’ or expressive (who have a more limited stereotypically masculine self-image) may be at increased risk of coronary disease. Further research on the link between social constructions of gender and health is needed.”

O xkcd publicou recentemente uma tirinha linda sobre uma certa orquídea:
(q1: “Existem orquídeas cujas flores se parecem com abelhas fêmeas. Quando abelhas machos tentam copular com elas, elas tarnsferem pólen.”
q2: “Esta orquídea, Ophrys apifera, faz flores mas nenhuma abelha pousa nelas porque a abelha que ela mimetiza se exinguiu muito tempo atrás.”
q3: “Sem seu parceiro, a orquídea apelou para a auto-polinização, uma estratégia genética desesperada que só retarda o inevitável. Nada sobrou da abelha, mas sabemos que ela existiu pela forma da flor.”
q4:”Esta é uma interpretação da lanta de como uma abelha fêmea é vista pela abelha macho” “Uau! Então…”
q5: “… a única memória da abelha é uma pintura feita por uma flor moribunda.”
q8: “Eu me lembrarei da su abelha, orquídea. Eu me lembrarei de você.”)
Muitas orquídeas possuem flores que imitam uma abelha fêmea a fim de atrair abelha machos para que elas transportem pólen de uma flor a outra. Outras espécies do gênero são polinizadas por abelhas que existem ainda hoje e esta é a única delas que tem auto-polinização. Algumas pessoas criticaram o autor da tirinha por utilizar uma linguagem poética que não é tão precisa quanto a linguagem científica. Eu discordo. Acho que ele conseguiu destilar muito bem o fenômeno científico na tirinha e ainda conseguiu colocar uma mensagem agridoce sobre a vida, o universo e tudo mais.
Um brinde à evolução!
Hipsters aside, most of the straight women I’ve talked to have stated a strong preference for clean-shaven men, which makes the research presented in this paper a bit of surprise. When shown pictures of the same men with differing facial hair lengths, both men and women expressed a preference for full beards and heavy stubble, respectively. But pictures are one thing, and beard burn is another. We demand a followup study that requires the participants to actually kiss those hairy faces!
The role of facial hair in women’s perceptions of men’s attractiveness, health, masculinity and parenting abilities.
“Facial hair strongly influences people’s judgments of men’s socio-sexual attributes. However, the nature of these judgments is often contradictory. The levels of intermediate facial hair growth presented to raters and the stage of female raters’ menstrual cycles might have influenced past findings. We quantified men’s and women’s judgments of attractiveness, health, masculinity and parenting abilities for photographs of men who were clean-shaven, lightly or heavily stubbled and fully bearded. We also tested the effect of the menstrual cycle and hormonal contraceptive use on women’s ratings. Women judged faces with heavy stubble as most attractive and heavy beards, light stubble and clean-shaven faces as similarly less attractive. In contrast, men rated full beards and heavy stubble as most attractive, followed closely by clean-shaven and light stubble as least attractive. Men and women rated full beards highest for parenting ability and healthiness. Masculinity ratings increased linearly as facial hair increased, and this effect was more pronounced in women in the fertile phase of the menstrual cycle, although attractiveness ratings did not differ according to fertility. Our findings confirm that beardedness affects judgments of male socio-sexual attributes and suggest that an intermediate level of beardedness is most attractive while full-bearded men may be perceived as better fathers who could protect and invest in offspring.”

HAHAHAHAHAHAHAHAH CARA. Que maravilhoso.
Of the 1000+ papers we have blogged about, this one is probably my favorite. Not only is it technically surprising (the scientists were able to identify which tissues and organs are present in the “meat” of different brands of supermarket-bought hotdogs by staining thin sections of the weiners), but it’s also supremely disgusting (nerve tissue and blood vessels…ugh). A winning combo, if there ever was one! Be sure to check out the awesome figure after the jump!
Applying morphologic techniques to evaluate hotdogs: what is in the hotdogs we eat?
“Americans consume billions of hotdogs per year resulting in more than a billion dollars in retail sales. Package labels typically list some type of meat as the primary ingredient. The purpose of this study is to assess the meat and water content of several hotdog brands to determine if the package labels are accurate. Eight brands of hotdogs were evaluated for water content by weight. A variety of routine techniques in surgical pathology including routine light microscopy with hematoxylin-eosin-stained sections, special staining, immunohistochemistry, and electron microscopy were used to assess for meat content and for other recognizable components. Package labels indicated that the top-listed ingredient in all 8 brands was meat; the second listed ingredient was water (n = 6) and another type of meat (n = 2). Water comprised 44% to 69% (median, 57%) of the total weight. Meat content determined by microscopic cross-section analysis ranged from 2.9% to 21.2% (median, 5.7%). The cost per hotdog ($0.12-$0.42) roughly correlated with meat content. A variety of tissues were observed besides skeletal muscle including bone (n = 8), collagen (n = 8), blood vessels (n = 8), plant material (n = 8), peripheral nerve (n = 7), adipose (n = 5), cartilage (n = 4), and skin (n = 1). Glial fibrillary acidic protein immunostaining was not observed in any of the hotdogs. Lipid content on oil red O staining was graded as moderate in 3 hotdogs and marked in 5 hotdogs. Electron microscopy showed recognizable skeletal muscle with evidence of degenerative changes. In conclusion, hotdog ingredient labels are misleading; most brands are more than 50% water by weight. The amount of meat (skeletal muscle) in most brands comprised less than 10% of the cross-sectional surface area. More expensive brands generally had more meat. All hotdogs contained other tissue types (bone and cartilage) not related to skeletal muscle; brain tissue was not present.”

This may be one of the best superpower-esque case studies we’ve seen to date. This 64-year-old patient with Parkinson’s can predict weather patterns based on his phantom smells. Wait–let’s unpack this a little. Here is a guy who smells stuff that isn’t there. Like “skunk-onion excrement odor”. (Skunk-onion excrement… is that a thing?) If that were all, it would be a real bummer. But not only does he smell these crazy phantom smells, he can actually use them to predict the weather. Sounds like the beginning of a pretty epic comic book series to me!
Phantosmia as a meteorological forecaster.
“In normosmics, olfactory ability has been found to vary with ambient humidity, barometric pressure, and season. While hallucinated sensations of phantom pain associated with changes in weather have been described, a linkage to chemosensory hallucinations has heretofore not been reported. A 64-year-old white male with Parkinson’s disease presents with 5 years of phantosmia of a smoky burnt wood which changed to onion-gas and then to a noxious skunk-onion excrement odor. Absent upon waking it increases over the day and persists for hours. When severe, there appears a phantom taste with the same qualities as the odor. It is exacerbated by factors that manipulate intranasal pressure, such as coughing. When eating or sniffing, the actual flavors replace the phantosmia. Since onset, he noted the intensity and frequency of the phantosmia forecasted the weather. Two to 3 h before a storm, the phantosmia intensifies from a level 0 to a 7-10, which persists through the entire thunderstorm. Twenty years prior, he reported the ability to forecast the weather, based on pain in a torn meniscus, which vanished after surgical repair. Extensive olfactory testing demonstrates underlying hyposmia. Possible mechanisms for such chemosensory-meteorological linkage includes: air pressure induced synesthesia, disinhibition of spontaneous olfactory discharge, exacerbation of ectopic discharge, affect mediated somatic sensory amplification, and misattribution error with expectation and recall bias. This is the first reported case of weather-induced exacerbation of phantosmia. Further investigation of the connection between chemosensory complaints and ambient weather is warranted.”
