In 2009, published genome-wide DNA data was not available for a single ancient human individual. Today, there is genome-wide data available for more than 6,000 ancient humans. This rapid expansion of ancient DNA (aDNA) research enables scientists to uncover more information than ever on past human populations, including their genetic adaptations, patterns of migration and mixing, and even clues about our species’ deep past. But this wide availability of aDNA brings ethical questions on how the data is gathered and used to the forefront.

The ongoing battles over COVID-19 vaccination in the U.S. are likely to get more heated when the Food and Drug Administration authorizes emergency use of a vaccine for children ages 5 to 11, expected later this fall.
41 patients undergoing primary total knee replacement at the Hospital for Special Surgery still had access to opioids, with the addition of electroacupuncture - small electric current to thin needles that are inserted - at eight specific points in the ear, And the majority of patients said acupuncture in their ear led to less opiod use. Sixty-five percent of patients maintained a low-dose opioid regimen of 15 oxycodone pills or less (57.5%) or remained completely opioid-free (7.5%) from induction of anesthesia to 30 days after surgery.
In the period during the housing crisis recession and the economic malaise that lasted until 2017, black households lost much more wealth than white families, regardless of class or profession, according to a new political science paper.
The COVID-19 pandemic may be the deadliest viral outbreak the world has seen in more than a century. But statistically, such extreme events aren’t as rare as we may think, asserts a new analysis of novel disease outbreaks over the past 400 years.
The study, appearing in the Proceedings of the National Academy of Sciences the week of Aug. 23, used a newly assembled record of past outbreaks to estimate the intensity of those events and the yearly probability of them recurring.
A study conducted in Hungarian schools showed that seating students next to each other boosted their tendency to become friends—both for pairs of similar students and pairs of students who differed in their educational achievement, gender, or ethnicity, according to the University of Leipzig, Germany, and colleagues.
Consumers are increasingly seeking products that are local, made by individually identified people, traditional, or remind them of their childhood and family growing up. This is evidenced by the ever-increasing popularity of farmers markets, hand-cut soap, artisanal bread, the locavore movement, and the return to familiar grocery brands during the COVID-19 pandemic. Locally rooted microbreweries, for example, were at the forefront of this renaissance of artisan, indie, and craft production. In 2019, craft beer accounted for 13.6% of total U.S.
DALLAS, July 26, 2021 -- Genomic studies have produced advances in how to calculate and reduce heart-disease risk, however, the benefits don't necessarily apply to people from historically marginalized racial and ethnic groups and Indigenous populations. Efforts must be made to eliminate barriers to increase their participation in genomic research, according to a new scientific statement from the American Heart Association, published today in the Association's journal Circulation: Genomic and Precision Medicine.
Citrus fruits from the mandarin family have important commercial value but how their diversity arose has been something of a mystery
Researchers analyzed the genomes of the East Asian varieties and found a second center of diversity in the Ryukyu Islands along with the previously known center in the mountains of southern China
They discovered a new citrus species native to Okinawa that arose about two million years ago when the Ryukyu archipelago became disconnected from mainland Asia
The Covid-19 pandemic and the politicization of health-prevention measures such as vaccination and mask-wearing have highlighted the need for people to accept and trust science.
But trusting science isn't enough.
A new study finds that people who trust science are more likely to believe and disseminate false claims containing scientific references than people who do not trust science. Reminding people of the value of critical evaluation reduces belief in false claims, but reminding them of the value of trusting science does not.
AMES, Iowa - A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes.
The study looks at a species of softshell turtle, but the results could help to illuminate an important evolutionary process in many species, said Nicole Valenzuela, professor of ecology, evolution and organismal biology and lead author of the study.
A new "return to campus" survey led by The Ohio State University's Office of the Chief Wellness Officer finds rising rates of anxiety, depression, burnout and the use of unhealthy coping mechanisms among students navigating through a year affected by the COVID-19 pandemic, similar to other data on college students throughout the U.S.
Ohio State conducted surveys in August 2020 and April 2021 of randomly-selected students to assess changes in mental health, coping strategies, healthy lifestyle behaviors and needs over time. Among the 1,072 Ohio State students who responded:
Oncotarget published "Frame-shift mediated reduction of gain-of-function p53 R273H and deletion of the R273H C-terminus in breast cancer cells result in replication-stress sensitivity" which reported that these authors recently documented that gain-of-function mutant p53 R273H in triple negative breast cancer cells interacts with replicating DNA and PARP1.
Researchers created a global dataset of job footprints in 50 countries and used a model to investigate how trying to meet the Paris Agreement global climate target of staying well below 2°C would affect energy sector jobs. They found that action to reach said target would increase net jobs by about 8 million by 2050, primarily due to gains in the solar and wind industries. The analysis appears July 23 in the journal One Earth.
Humid tropical forests, vital in global efforts to limit rising temperatures, are under threat as a result of changes in land use and climate. Now, researchers reporting in the journal One Earth on July 23 have developed a new way to keep tabs on the vulnerability of these forests on a global scale using satellite data. Called the tropical forest vulnerability index (TFVI), the hope is that this method will serve as an early warning for areas that are under the greatest threat to enable actions aimed at protecting these forests before it's too late.
