White people and non-black minorities have a harder time telling the difference between genuine and fake smiles on black faces than they do on white faces, a problem black people don’t have, according to research published by the American Psychological Association.
Researchers at the George Washington University gained important insights into how the human brain processes information and allocates attention. Their study, “Attention Scales According to Inferred Real-World Object Size,” shows people pay attention to objects based on their real-world size, rather than how they are perceived by the eye.

People make statistically-informed judgments about who is more likely to hold particular professions even though they criticize others for the same behavior, according to findings published in Psychological Science, a journal of the Association for Psychological Science.
In this special Sepsis Issue, AACC’s The Journal of Applied Laboratory Medicine highlights the cutting-edge clinical tests that laboratory medicine experts are developing to combat sepsis, a life-threatening condition that kills more people in the U.S. than heart attacks every year.
A first-of-its-kind study indicates that male partners of women with recurrent pregnancy loss have reduced sperm quality caused by impaired reproductive hormone production and high oxidant levels. This research, published in the Men’s Health Issue of AACC’s Clinical Chemistry journal, could help more couples with recurrent pregnancy loss to conceive by leading to new treatments that improve male partners’ reproductive health.
Novel studies published in the Men’s Health Issue of AACC’s journal Clinical Chemistry suggest that hormone therapy for transgender people increases the risk of blood clots less than birth control pills and does not increase the risk of cardiovascular disease at all. These preliminary results could help more transgender individuals to access essential hormone therapy by increasing physician comfort with prescribing it.
In a special Men’s Health Issue, AACC’s Clinical Chemistry journal spotlights breaking research that is crucial for men—and for patient populations with which men’s health isn’t historically associated, from transgender individuals to pregnant women. This issue aims not only to address men’s unmet health needs, but also to reduce health disparities by promoting dialogue between the men’s, women’s, and transgender health fields.
• In a study of African-American men and women with normal kidney function, a pattern of higher collective consumption of soda, sweetened fruit drinks, and water was associated with a higher risk of developing kidney disease.
• Patients on peritoneal dialysis and their caregivers give high priority to clinical outcomes (such as infection and mortality) and many patient-reported outcomes (particularly fatigue and flexibility with time), which are absent in most trials in peritoneal dialysis.
Direct-to-consumer DNA testing kits are expected to be a popular holiday gift this year, with 100 million people expected to have used one by 2020—but an expert genetic counselor at Georgetown says consumers should understand a few pros and cons before using one.
Researchers from the George Washington University received more than $3.1 million from the National Institutes of Health to investigate the causes of cardiovascular disease in HIV-infected patients
People who value following purity rules over caring for others are more likely to view gay and transgender people as less human, which leads to more prejudice and support for discriminatory public policies, according to a new study published by the American Psychological Association.
New model provides more accurate estimates of how fast microbes produce a mercury-based neurotoxin.
The holiday season can be a time of excess, but low- or no-calorie sweeteners could help merry-makers stay trim. Stevia is a zero-calorie sweetener that is sometimes called “natural” because it is extracted from the leaves of a South American plant. Now, a report in ACS Synthetic Biology describes a way to prepare large quantities of stevia using yeast, which would cut out the plant middleman and could lead to a better tasting product.
Skin has a remarkable ability to heal itself. But in some cases, wounds heal very slowly or not at all, putting a person at risk for chronic pain, infection and scarring. Now, researchers have developed a self-powered bandage that generates an electric field over an injury, dramatically reducing the healing time for skin wounds in rats. They report their results in ACS Nano.
Many of us view the year’s end as a time for reflection, and chemists are no different. As we say goodbye to 2018, Chemical & Engineering News (C&EN), the weekly news magazine of the American Chemical Society, highlights the year’s biggest chemistry trends, most memorable molecules and more in a special issue. As part of its wrap-up, the magazine peers into its crystal ball to predict the hottest chemistry advances to watch for in 2019.
Our homes are supposed to be safe havens from the outside world. However, studies have shown that household air is more polluted than either office or school air, exposing children and home workers to higher levels of carcinogens than the general population. Now, researchers have made a genetically modified houseplant that can efficiently remove at least two toxins from the air. They report their results in ACS’ journal Environmental Science & Technology.

When two events occur within a brief window of time they become linked in memory, such that calling forth memory of one helps retrieve memory for the other event, according to research published in Psychological Science, a journal of the Association for Psychological Science. This happens even when temporal proximity is the only feature that the two events share.

The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) launched the Escape Respirator Challenge, a $250,000 prize competition that seeks new concepts for an escape respirator solution.
• Dialysis reimbursement policies in most countries are focused on conventional in-center hemodialysis, although home hemodialysis and peritoneal dialysis might contribute to quality of life and cost savings. • The reimbursement for dialysis in low- and middle-income countries is insufficient to treat all patients with kidney failure and has a disproportionately high impact on public health expenditure in those countries.
