It would be a big surprise if a prominent journal published a study commissioned by the dating website eHarmony showing that people who met through online dating were more miserable than those who met through friends, work, bars, etc. Funny that such results rarely appear. The potential conflicts of interest here were at least as interesting as the results of the study, which entailed a large survey of couples married between and

In this study, we focus on the resolution limits for quasi 2-D single lines synthesized via focused electron-beam-induced direct-write deposition at 5 and 30 keV in a scanning electron microscope. To understand the relevant proximal broadening effects, the substrates were thicker than the beam penetration depth and we used the MeCpPt IV Me 3 precursor under standard gas injection system conditions.
It is shown by experiment and simulation how backscatter electron yields increase during the initial growth stages which broaden the single lines consistent with the backscatter range of the deposited material. By this it is shown that the beam diameter together with the evolving backscatter radius of the deposit material determines the achievable line widths even for ultrathin deposit heights in the subnm regime.

Beer is one of the oldest drinks humans have produced. The first chemically confirmed barley beer dates back to at least the 5th millennium BC in Iran, and was recorded in the written history of ancient Egypt and Mesopotamia and spread throughout the world. Though, the ancient Chinese artifacts suggested that beer brewed with grapes, honey, hawthorns, and rice were produced as far back as 7, BC. As almost any cereal containing certain sugars can undergo spontaneous fermentation due to wild yeasts in the air, it is possible that beer-like drinks were independently developed throughout the world soon after a tribe or culture had domesticated cereal.
Chemical tests of ancient pottery jars reveal that beer was produced as far back as about 7, years ago in what is today Iran. In Mesopotamia, the oldest evidence of beer is believed to be a 6,year-old Sumerian tablet depicting people consuming a drink through reed straws from a communal bowl. A 3,year-old Sumerian poem honouring Ninkasi , the patron goddess of brewing, contains the oldest surviving beer recipe, describing the production of beer from bread made from barley.
In China, residue on pottery dating from around 5, years ago shows beer was brewed using barley and other grains. The invention of bread and beer has been argued to be responsible for humanity’s ability to develop technology and build civilization. Beer may have been known in Neolithic Europe as far back as 5, years ago,  and was mainly brewed on a domestic scale.
Beer produced before the Industrial Revolution continued to be made and sold on a domestic scale, although by the 7th century AD beer was also being produced and sold by European monasteries. During the Industrial Revolution, the production of beer moved from artisanal manufacture to industrial manufacture , and domestic manufacture ceased to be significant by the end of the 19th century. Today, the brewing industry is a global business, consisting of several dominant multinational companies and many thousands of smaller producers ranging from brewpubs to regional breweries.

PNAS is an important scientific journal that printed its first issue in and continues to publish highly cited research reports, commentaries, reviews, perspectives, feature articles, profiles, letters to the editor, and actions of the Academy. Coverage in PNAS broadly spans the biological, physical, and social sciences. Although most of the papers published in the journal are in the biomedical sciences, PNAS recruits papers and publishes special features in the physical and social sciences and in mathematics.
The NAS itself had been founded in as a private institution, but chartered by the US Congress, with the goal to “investigate, examine, experiment, and report upon any subject of science or art. For more than years, humans have mastered the art of refracting light by shaping glass into lenses, then bending or combining those lenses to amplify and clarify images either close-up and far-off.

If you’re young and single, chances are you’re rejecting potential dates left and right on apps like Tinder, Bumble and OkCupid. It’s a brutal virtual world. Hundreds of people are whittled down to a few in minutes. In the seconds you lingered on one person’s profile, four pictures and an ambiguous job title, what made you swipe him or her to the right? First impressions count in ways you might not expect. How people sit or where their arms and legs are in the images they share seem to loom large in potential daters’ calculations, according to experiments involving speed dating and an online dating app.
One of the guys in the study displays an expansive body posture left that led to a better dating response than the contracted posture, a real downer. In these experiments, the researchers compared young adults’ closed, slouched postures against open, or expanded, ones. For the speed daters, Vacharkulksemsuk says, “expansiveness nearly doubles chances of getting a yes [to see each other again. Separately, she and her colleagues had three men and three women create two dating profiles each on a popular dating app.

Print version. This interactive module is designed to promote an understanding of unconscious bias and how it can affect the peer review process. It will also provide strategies for mitigating bias during the review process. In this section, we will explore the difference between explicit bias and implicit or unconscious bias. When faced with situations or people, we use mental maps and patterns to classify them by making a number of automatic associations.
Not surprisingly, our perceptions and assumptions based on these automatic associations are not always correct. Because our unconscious biases tend to be ingrained, it takes some work to disrupt them, but it can be done through active reflection and practicing inclusive behaviours. Doing this work benefits us, the people around us and the peer review process; it also contributes to research excellence. You are out with friends and see someone wearing a sports jersey from your favourite team.
You decide that you like them and decide to have a friendly conversation with them. In this situation, you are consciously aware of the reason that you like that person. You make a deliberate decision to talk to them and you are aware of the process by which you reached that decision. This is an example of explicit bias. Explicit bias is a result of conscious thought and can be deliberately regulated.

No benefit was seen with a day course of the antiviral. A study in PNAS based on data from five counties in Georgia highlights the contribution of superspreading to the pandemic , particularly in rural areas. Moreover, people younger than 60 appear to be more likely to be superspreaders than their older counterparts. Another study in PNAS , out of Germany, suggests that mandatory mask policies have advantages over voluntary ones.
Broader testing resulted in a median A sweeping meta-analysis combining more than 77, hospitalized COVID patients from around the world— published in PLOS One —confirms that a significant proportion have cardiovascular symptoms or develop cardiovascular complications postinfection, and shows that both are associated with a higher risk of dying, TCTMD Managing Editor Shelley Wood reports.
At two centers in London, England, there was a reduction in heart failure hospitalizations and an increase in in-hospital mortality, according to a study in the European Journal of Heart Failure. They argued that the evidence was not strong enough to support the move. Among patients with large acute ischemic strokes, those who presented during the COVID pandemic had more severe events than those who presented in , a study in Stroke shows.
The rate of successful recanalization did not differ between the two time periods, although in-hospital mortality was much higher in The incidence of lab-confirmed disease was 3. The very virus that has brought about record unemployment levels is the same agent that makes health insurance—and the new options created under the ACA—more important than ever. During the pandemic, there were declines in delivery of CPR and use of automated external defibrillators.

Some acronyms are useful and are widely understood, but many of the acronyms used in scientific papers hinder understanding and contribute to the increasing fragmentation of science. Here we report the results of an analysis of more than 24 million article titles and 18 million article abstracts published between and Acronym use has also increased over time, but the re-use of acronyms has declined.
We found that from more than one million unique acronyms in our data, just over 2, 0. Acronyms are not the biggest current problem in science communication, but reducing their use is a simple change that would help readers and potentially increase the value of science. As the number of scientific papers published every year continues to grow, individual papers are also becoming increasingly specialised and complex Delanty, ; Bornmann and Mutz, ; Doubleday and Connell, ; Cordero et al.
Writing scientific papers that are clearer to read could help to close this gap and increase the usefulness of scientific research Freeling et al. One feature that can make scientific papers difficult to read is the widespread use of acronyms Sword, ; Pinker, ; Hales et al. For example, the acronym UA has 18 different meanings in medicine Lang,
