How human brain development diverged from that of great apes
Researchers present new insights into the development of the human brain and differences in this process compared to other great apes. The study reveals features of brain development that are unique to humans, and outlines how these processes have diverged from those in other primates.

Researchers clarify mechanisms that allow hard-to-treat cancers to develop, and have identified strategies that could lead to new therapies.
Read moreAcaí berry extracts fight malaria in mice
Despite humanity's best efforts to eradicate malaria, the disease struck more than 200 million people in 2017, according to the World Health Organization. Worse yet, the parasite that causes malaria is developing resistance to many antimalarial drugs, including the mainstay, chloroquine. Researchers are actively searching for new treatments, and now, a group have found that acaí berry extracts can reduce parasites in the blood and prolong the survival of infected mice.
Read moreScientists discover skin keeps time independent of the brain
A study has now found that a type of opsin known as neuropsin is expressed in the hair follicles of mice and synchronize the skin's circadian clock to the light-dark cycle, independent of the eyes or brain. Researchers now want to see if skin heals better if it's exposed to certain types of light.

New research signposts a new, less invasive approach to identify killer T lymphocytes in patients with gastrointestinal tumors with low mutational burden who are refractory to approved immune-based treatments.
Read moreIn a first, scientists pinpoint neural activity's role in human longevity
Researchers discover that the activity of the nervous system might influence human longevity. Neural excitation linked to shorter life, while suppression of overactivity appears to extend life span. Protein REST, previously shown to protect aging brains from dementia and other diseases, emerges as a key player in molecular cascade related to aging. Findings suggest future avenues for intervention in diseases ranging from Alzheimer's to bipolar disorder.
Read moreGas 'waterfalls' reveal infant planets around young star
For the first time, astronomers have witnessed 3D motions of gas in a planet-forming disk. At three locations in the disk around a young star called HD 163296, gas is flowing like a waterfall into gaps that are most likely caused by planets in formation. These gas flows have long been predicted and would directly influence the chemical composition of planet atmospheres.

A study describes a new rapid assay for Lyme disease that could lead to a practical test for use by healthcare providers. The researchers found the assay, which uses several biomarkers to detect Lyme disease infection, was more sensitive than current laboratory-based tests when diagnosing Lyme disease early after suspected infection.
Read more3-D printed coral could help endangered reefs
Threats to coral reefs are everywhere — rising water temperatures, ocean acidification, coral bleaching, fishing and other human activities. But new research shows that 3-D printed coral can provide a structural starter kit for reef organisms and can become part of the landscape as fish and coral build their homes around the artificial coral.
