Researchers say that the ability to "diagnose" the skills teen drivers lack may provide opportunities for better driving practice in a safe environment, so that teens are better prepared to navigate hazardous situations when they take to the road alone.
Scientists in the STAR collaboration at the Relativistic Heavy Ion Collider, a particle accelerator exploring nuclear physics and the building blocks of matter at the U.S. Department of Energy's Brookhaven National Laboratory, have new evidence for what's called a "chiral magnetic wave" rippling through the soup of quark-gluon plasma created in RHIC's energetic particle smashups. The findings are described in a paper that will be highlighted as an Editors' Suggestion in Physical Review Letters.
When it comes to the three-horned dinosaur called the Triceratops, science is showing the ancient creatures might have been a little more complex than we thought. In fact, their teeth were far more intricate than any reptile or mammal living today.
A team of scientists have taken quantum teleportation – a method of communicating information from one location to another without having to physically move it – to a higher level by using certain high-dimensional states (which they dubbed “donut” states) for teleportation. Stony Brook University physicist Tzu-Chieh Wei, PhD, and colleagues nationally demonstrated that their method works, is more reliable than previous teleportation schemes, and could be a stepping stone toward building a quantum communications network. Their findings appear in Nature Communications.
New research has revealed that parasitic ‘vampire’ plants that attach onto and derive nutrients from another living plant may benefit the abundance and diversity of surrounding vegetation and animal life.
Archaeologists at the University of Southampton have found evidence of an ancient gold trade route between the south-west of the UK and Ireland. A study suggests people were trading gold between the two countries as far back as the early Bronze Age (2500BC).
An artificial intelligence system has reverse-engineered the regeneration mechanism of planaria, a common model in regenerative medicine. This is the first reported model of regeneration discovered by a non-human intelligence, and the first comprehensive model of planarian regeneration, which has long eluded human scientists.
In a breakthrough for computer vision and for bird watching, researchers and bird enthusiasts have enabled computers to achieve a task that stumps most humans—identifying hundreds of bird species pictured in photos.
What is it with cheating? Cheaters seem to have an immediate advantage over cooperators, but do they have an evolutionary advantage? A study published in Current Biology suggests the benefits of cheating change with its prevalence,in a population. Cheaters may succeed, for example, only when they are rare, and fail when they become so numerous they push out cooperators.

Though people can distinguish among millions of colors, we have trouble remembering specific shades because our brains tend to store what we’ve seen as one of just a few basic hues.
New research suggests that methanogens – among the simplest and oldest organisms on Earth – could survive on Mars.
A study of marine mammals finds that several once endangered species, including the humpback whale, the northern elephant seal and green sea turtles, have recovered and are repopulating their former ranges. But returning species create a new challenge: some people interpret the return of these animals as a hostile invasion. The study presents strategies for “lifting baselines” to help manage and celebrate recovering species.
A rare eye disorder marked by color blindness, light sensitivity, and other vision problems can result from a newly discovered gene mutation identified by an international research team, including scientists from Columbia University Medical Center (CUMC). The findings, which were published today in the online edition of Nature Genetics, could lead to new, targeted treatments for this form of color blindness.

Reporting on their study with lab-grown human cells, researchers at The Johns Hopkins University and the University of Maryland say that blocking a second blood vessel growth protein, along with one that is already well-known, could offer a new way to treat and prevent a blinding eye disease caused by diabetes.
In a new twist on the use of DNA in nanoscale construction, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators put synthetic strands of the biological material to work in two ways: They used ropelike configurations of the DNA double helix to form a rigid geometrical framework, and added dangling pieces of single-stranded DNA to glue nanoparticles in place.
Madagascar is home to extraordinary biodiversity, but in the past few decades, the island’s forests and associated biodiversity have been under greater attack than ever. Rapid deforestation is affecting the biotopes of hundreds of species, including the panther chameleon, a species with spectacular intra-specific colour variation. A new study by Michel Milinkovitch, professor of genetics, evolution, and biophysics at the University of Geneva (UNIGE), led in close collaboration with colleagues in Madagascar, reveals that this charismatic reptilian species, which is only found in Madagascar, is actually composed of eleven different species. The results of their research appear in the latest issue of the Molecular Ecology journal. They also discuss the urgent need to protect Madagascar’s habitats.
This new result has allowed researchers to determine the reason behind a large discrepancy in the data between two different methods used to measure the proton’s electric form factor.
Astronomers have spent decades trying to determine the oddball behavior of an aging star nicknamed "Nasty 1" residing in our Milky Way galaxy. Looking at the star using NASA's Hubble Space Telescope, astronomers had expected to see a bipolar outflow of twin lobes of gas from the star. The astronomers were surprised, however, to find a pancake-shaped disk of gas encircling the star. The vast disk is nearly 1,000 times the diameter of our solar system.

Researchers at the University of Colorado suggest that the portion of the brain devoted to hearing can become reorganized even with early-stage hearing loss, and may play a role in cognitive decline. They have applied fundamental principles of neuroplasticity, the ability of the brain to forge new connections, to determine the ways it adapts to hearing loss, as well as the consequences of those changes, and their findings will be presented at ASA’s 169th meeting.
Modern lifestyles have made our bones lighter weight than our hunter-gatherer ancestors. A study of the bones of hundreds of humans who lived during the past 33,000 years in Europe finds the rise of agriculture and a corresponding fall in mobility drove the change, rather than urbanization, nutrition or other factors.
U.S. residents' exposure to extreme heat could increase four- to six-fold by mid-century, due to both a warming climate and a population that's growing especially fast in the hottest regions of the country, according to new research by NCAR scientists.
