Studies of wolf spiders found that courtship displays help preserve genetic isolation between closely related species. Another study found that the species Gladicosa bellamyi used multi-modal communication to entice females.

In a vulnerable forest in southeastern Brazil, where the air was once thick with the guttural chatter of brown howler monkeys, there now exists silence. Yellow fever, a virus carried by mosquitoes and endemic to Africa and South America, has robbed the private, federally-protected reserve of its brown howlers in an unprecedented wave of death that has swept through the region since late 2016, killing thousands of monkeys.

A fungal biopesticide that shows promise for the control of bed bugs is highly effective even against bed-bug populations that are insecticide resistant, according to research.

A survey of more than 422,000 college freshmen found that students who identified as transgender were more likely than their cisgender peers to experience negative consequences from drinking, including memory blackouts, academic problems and conflicts such as arguments or physical fights.

A DNA study of endangered greater prairie chickens in Illinois indicates that supplementing the dwindling population with birds from out of state did not improve genetic diversity.

Researchers face a fundamental challenge as they seek to scale up human tissue regeneration from small lab samples to full-size tissues and organs: how to establish a vascular system that delivers blood deep into the developing tissue. Researchers have now successfully turned to plants, culturing beating human heart cells on spinach leaves that were stripped of plant cells.

A molecule found in car engine exhaust fumes that is thought to have contributed to the origin of life on Earth has made astronomers heavily underestimate the amount of stars that were forming in the early Universe, a study has found. That molecule is called polycyclic aromatic hydrocarbon. On Earth it is also found in coal and tar. In space, it is a component of dust.

Both humans and smartphones show a degree of error in distinguishing face morph photos from their 'real' faces on fraudulent identity cards, new research has found.

Structure organizes human activities and help us understand the world with less effort, but it can be the killer of creativity, concludes a new study.

A new report demonstrates that an optical imaging tool used to monitor regional blood flow and tissue oxygenation may be used to track the brain's response to acute pain in infants, children, and adults.

It's not every day someone gets to say, 'I've discovered a new species.' It's a claim that biologist Chris Funk can happily make. Funk and collaborators, who've spent years exploring the tropical climes of South America to study the region's dizzying biodiversity, have documented a new species of rainfrog they've named the Ecuadorian rainfrog (Pristimantis ecuadorensis).

The brains of those who are born blind make new connections in the absence of visual information, resulting in enhanced, compensatory abilities such as a heightened sense of hearing, smell and touch, as well as cognitive functions (such as memory and language) according to a new study.

Researchers report the discovery of a new technique that could drastically improve the sensitivity of instruments such as magnetic resonance imagers (MRIs) and atomic clocks. The study reports a technique to bypass the Heisenberg uncertainty principle. This technique hides quantum uncertainty in atomic features not seen by the instrument, allowing the scientists to make very high precision measurements.

The Ebola virus causes a severe, often fatal illness when it infects the human body. Initially targeting cells of the immune system called macrophages, white blood cells that absorb and clear away pathogens, a new study has found a way to potentially 'silence' these Ebola virus-infected macrophages.

Marine protected areas (MPAs) are an increasingly popular strategy for protecting marine biodiversity, but a new global study demonstrates that widespread lack of personnel and funds are preventing MPAs from reaching their full potential. Only 9 percent of MPAs reported having adequate staff.

Patients who underwent ambulatory breast reconstruction and used a mobile app for follow-up care had fewer in-person visits during the first 30 days after the operation without affecting complication rates or measures of patient-reported satisfaction, according to a study.

New archaeological analysis suggests people of Western Roman Empire switched between Hunnic nomadism and settled farming over a lifetime. Findings may be evidence of tribal encroachment that undermined Roman Empire during 5th century AD, contributing to its fall.

Using video microscopy in the living mouse lung, scientists have revealed that the lungs play a previously unrecognized role in blood production.

The earliest mutations of human life have been observed by researchers. Analyzing genomes from adult cells, the scientists could look back in time to reveal how each embryo developed. The study shows that from the two-cell stage of the human embryo, one of these cells becomes more dominant than the other and leads to a higher proportion of the adult body.

More than a century of theory about the evolutionary history of dinosaurs has been turned on its head following the publication of new research. The work suggests that the family groupings need to be rearranged, redefined and renamed and also that dinosaurs may have originated in the northern hemisphere rather than the southern, as current thinking goes.
