After more than a decade, ChIP-seq may be quantitative after all

For more than a decade, scientists studying epigenetics have used a powerful method called ChIP-seq to map changes in proteins and other critical regulatory factors across the genome. While ChIP-seq provides invaluable insights into the underpinnings of health and disease, it also faces a frustrating challenge: its results are often viewed as qualitative rather than quantitative, making interpretation difficult.

Study: Countering hate on social media

The rise of online hate speech is a disturbing, growing trend in countries around the world, with serious psychological consequences and the potential to impact, and even contribute to, real-world violence. Citizen-generated counter speech may help discourage hateful online rhetoric, but it has been difficult to quantify and study. Until recently, studies have been limited to small-scale, hand-labeled endeavors.

Science reveals secrets of a mummy's portrait

How much information can you get from a speck of purple pigment, no bigger than the diameter of a hair, plucked from an Egyptian portrait that's nearly 2,000 years old? Plenty, according to a new study. Analysis of that speck can teach us about how the pigment was made, what it's made of—and maybe even a little about the people who made it. The study is published in the International Journal of Ceramic Engineering and Science.

Frequent, rapid testing could cripple COVID within weeks, study shows

Limited access to buprenorphine restricts resident physicians treating opioid abusers

A survey of resident physicians in Florida indicates they are interested in treating opioid addiction but face barriers to offering patients treatment using buprenorphine, an FDA-approved medication shown to successfully decrease opioid use, overdose events, and deaths associated with opioids.

The microbiome of Da Vinci's drawings

The work of Leonardo Da Vinci is an invaluable heritage of the 15th century. From engineering to anatomy, the master paved the way for many scientific disciplines. But what else could the drawings of Da Vinci teach us? Could molecular studies reveal interesting data from the past? These questions led an interdisciplinary team of researchers, curators and bioinformaticians, from both the University of Natural Resources and Life Science and the University of Applied Science of Wien in Austria, as well as the Central Institute for the Pathology of Archives and Books (ICPAL) in Italy, to collaborate and study the microbiome of seven different drawings of Leonardo Da Vinci.

Researchers reverse severe lymphatic disorder in patient with Noonan syndrome

Researchers at Children's Hospital of Philadelphia (CHOP) have resolved a severe lymphatic disorder in a girl with Noonan Syndrome that had led to upper gastrointestinal bleeding, fluid collection around the lungs, and numerous surgeries that had been unable to resolve her symptoms. By identifying a genetic mutation along a pathway related to lymphatic vessel development and function, the research team was able to target the pathway using an existing drug they had used in a previous case to remodel a patient's lymphatic system.

Climate change and 'atmospheric thirst' to increase fire danger and drought in NV and CA

Climate change and a "thirsty atmosphere" will bring more extreme wildfire danger and multi-year droughts to Nevada and California by the end of this century, according to new research from the Desert Research Institute (DRI), the Scripps Institution of Oceanography at the University of California, San Diego, and the University of California, Merced.

Predicting preterm births

Predicting preterm birth can be difficult, especially for women who have not given birth. It has long been known that the best predictor of preterm birth is someone who has had a prior preterm birth; however, this information is helpful only in second and subsequent pregnancies. For women in their first pregnancy, it is a challenge for obstetricians and midwives to advise them on their risks. To address this issue, researchers at Baylor College of Medicine and Texas Children's Hospital studied how family history can predict preterm birth. Their findings were published in the American Journal of Obstetrics & Gynecology.

College students are less food insecure than non-students

Infectiousness peaks early in COVID-19 patients, emphasising the need to rapidly isolate cases: study

Although SARS-CoV-2 genetic material may still be detected in respiratory or stool samples for several weeks, no live virus (that can cause infection) was found in any type of sample collected beyond nine days of symptoms starting and people with SARS-CoV-2 are mostly likely to be highly infectious from symptom onset and the following five days, according to a systematic review and meta-analysis of three human coronaviruses published in The Lancet Microbe journal.

How rotavirus causes severe gastrointestinal disease

Rotavirus is a major cause of diarrhea and vomiting, especially in children, that results in approximately 128,000 deaths annually. The virus triggers the disease by infecting enterocyte cells in the small intestine, but only a fraction of the susceptible cells has the virus. In the mid-90s, scientists proposed that the small portion of infected cells promotes severe disease by sending out signals that disrupt the normal function of neighboring uninfected cells, but the nature of the signal has remained a mystery.

Spill-over effects show prioritising education of very poorest improves attainment of all

International development projects that target the education of the world's very poorest children and marginalised girls also significantly improve other young people's attainment, according to new research that suggests such initiatives should become a priority for international aid.

Children's Hospital Los Angeles conducts largest pediatric genomic COVID-19 study to date

When it comes to children, it is becoming clear that COVID-19 impacts them more than was initially realized. Yet there is relatively little information about SARS-CoV-2, the virus that causes the disease, in pediatric populations. Scientists at Children's Hospital Los Angeles have just published the largest pediatric COVID-19 study to date, suggesting, for the first time, a possible link between specific viral mutations and severity of the disease.
