A first-of-its-kind clinical trial involving more than 600 children in Kenya and Tanzania, in which community members were trained to deliver mental health treatment, showed improvement in participants' trauma-related symptoms up to a year after receiving therapy, new research shows.
An international team led by Harvard Medical School scientists has produced the first genome-wide ancient human DNA sequences from west and central Africa.
The data, recovered from four individuals buried at an iconic archaeological site in Cameroon between 3,000 and 8,000 years ago, enhance our understanding of the deep ancestral relationships among populations in sub-Saharan Africa, which remains the region of greatest human diversity today.
Curtin University scientists have discovered Earth's oldest asteroid strike occurred at Yarrabubba, in outback Western Australia, and coincided with the end of a global deep freeze known as a Snowball Earth.
The research, published in the leading journal Nature Communications, used isotopic analysis of minerals to calculate the precise age of the Yarrabubba crater for the first time, putting it at 2.229 billion years old - making it 200 million years older than the next oldest impact.
A new high-throughput method has revealed metals previously undetected in 3-D protein structures. The study, led by the Universities of Surrey and Oxford, is thought to have major implications for scientists using protein structure data.
Police have long relied on the unique whorls, loops or arches encoded in fingerprints to identify suspects. However, they have no way to tell how long ago those prints were left behind -- information that could be crucial to a case. A preliminary new study in ACS' Analytical Chemistry suggests that could change. Researchers report that they could link compounds contained in fingerprints with their age.
DURHAM, N.C. -- Wide swings in blood pressure readings among young adults are associated with a higher risk of cardiovascular disease by middle age, a new analysis led by Duke Health researchers shows.
The finding, publishing Jan. 22 in JAMA Cardiology, suggests that the current practice of averaging blood pressure readings to determine whether medications are necessary could be masking a potential early warning sign from the fluctuations themselves.
It's a scene that some cancer patients dream about: they celebrate the end of a course of radiation or chemotherapy by ringing a bell, surrounded by family and cheering cancer clinic staff. Indeed, many patients say they love the graduation-like ceremony and the sense of closure it gives them.
According to ancient lore, Genghis Khan instructed his horsemen to wear silk vests underneath their armor to better protect themselves against an onslaught of arrows during battle. Since the time of Khan, body armor has significantly evolved -- silk has given way to ultra-hard materials that act like impenetrable walls against most ammunition. However, even this armor can fail, particularly if it is hit by high-speed ammunition or other fast-moving objects.
ROCHESTER, Minn. -- Mesenchymal stromal cells from fat tissue and bone marrow are widely used in therapeutic trials for their anti-inflammatory qualities, but new Mayo Clinic research finds that liver cells may be of greater value.
The study, published in Liver Transplantation, finds that liver mesenchymal stromal cells have immunoregulatory qualities that make them more effective than similar cells derived from adipose, or fat, tissue and bone marrow.
La Jolla, California (January 18, 2020). A new study published in the Journal of Clinical Investigation enrolled people with HIV who also happened to have a terminal illness to study where HIV hides in the human body so doctors can better treat and maybe even cure HIV.
Selfless Terminally Ill Persons Join Doctors To Study HIV
"When looking at the status of planet Earth and the influence of current global agriculture practices upon it, there's a lot of reason to worry, but also reason for hope - if we see decisive actions very soon," Dieter Gerten says, lead author from PIK and professor at Humboldt University of Berlin. "Currently, almost half of global food production relies on crossing Earth's environmental boundaries. We appropriate too much land for crops and livestock, fertilize too heavily and irrigate too extensively.
A study involving researchers from King's College London, has developed a predictive tool that can recognise adolescents who are at high or low risk of depression in young adulthood.
Using data from over 2,000 Brazilian adolescents, the researchers developed the tool that can help identify which young people will go on to experience a major depressive disorder when they reach 18 years.
Scientists say a type of algae crucial to the survival of coral reefs may be able to resist the impacts of ocean acidification caused by climate change.
In a world-first, the team--including researchers from the ARC Centre of Excellence for Coral Reef Studies at The University of Western Australia (Coral CoE at UWA)--found that coralline algae are able to build tolerance to ocean acidification over multiple generations.
Scientific and public appreciation for microbes--and the key role their communal actions play in environmental health, food production, and human wellness--has grown in recent years. While initially considered to be static, uniform entities, microbial communities are highly complex and contain internal chemical swapfests that are in constant flux.
EAST LANSING, Mich. - Have I got a fish story for you. Any angler beginning a yarn like that usually ends up spinning a tall tale, an exaggeration or bald-faced lie.
Michigan State University researchers, however, have demonstrated that anglers can produce accurate and complex environmental models similar to those of trained scientists.
The study, led by graduate student Payam Aminpour and Steven Gray, community sustainability professor, shows that fisheries stakeholders can accurately predict pike populations, predator abundance, habitat and fishing pressure.
