Engineers 3D-print a New Lifelike Liver Tissue for Drug Screening

A team led by engineers at the University of California, San Diego has 3D-printed a tissue that closely mimics the human liver’s sophisticated structure and function. The new model could be used for patient-specific drug screening and disease modeling. The work was...

2015 was the worst year on record for shark attacks

It’s the kind of record no one wants to break: the most shark attacks in a single year. But 2015 did just that, with 98 unprovoked attacks worldwide, beating the previous record of 88 set in 2000, according to the International Shark Attack File housed at the...

In autism, the social benefits of being a girl

Infant girls at risk for autism pay more attention to social cues in faces than infant boys, according to a Yale School of Medicine study — the first one known to prospectively examine sex-related social differences in at-risk infants. This difference in observational...

A football helmet design that listens to physics

A shock-absorbing football helmet system being developed at the University of Michigan could blunt some dangerous physics that today’s head protection ignores. The engineering researchers making the system, called Mitigatium, were recently funded by a group that...

Double Dose of Bad Earthquake News

A team of researchers, including one from the University of California, Riverside, has discovered that earthquake ruptures can jump much further than previously thought, a finding that could have severe implications on the Los Angeles area and other regions in the...

Earth-like planets have Earth-like interiors

Every school kid learns the basic structure of the Earth: a thin outer crust, a thick mantle, and a Mars-sized core. But is this structure universal? Will rocky exoplanets orbiting other stars have the same three layers? New research suggests that the answer is yes...

No more hippy trail routes as backpackers become tourists

Low cost airlines, natural disasters, regional competition, tightening visa rules and terrorism have all changed backpacking in South East Asia. In his paper Change, Choice, and Commercialization: Backpacker Routes in Southeast Asia for the international journal...

Millennials say one thing but do another when choosing chocolate

The majority of millennials may not be putting their money where their mouths are when selecting chocolate, according to a Kansas State University expert in psychological sciences. Despite strong preferences for ethical chocolate in focus groups, only 14 percent of...

Wolf species have ‘howling dialects’

The largest ever study of howling in the ‘canid’ family of species — which includes wolves, jackals and domestic dogs — has shown that the various species and subspecies have distinguishing repertoires of howling, or “vocal...

Researchers seek efficient means of splitting water

Photovoltaics promise to help meet our energy needs by turning sunlight into electricity. We can’t run everything that way, but with a little tweaking, photovoltaic materials can use solar energy to split water into hydrogen and oxygen. Cornell researchers are...

Faces of black children as young as 5 evoke negative biases

A new study suggests that people are more likely to misidentify a toy as a weapon after seeing a Black face than a White face, even when the face in question is that of a five-year-old child. The research is published in Psychological Science, a journal of the...

Human culture, not smarts, may have overwhelmed Neanderthals

What happened to the Neanderthals? They left their African homes and migrated into Europe 350,000 to 600,000 years ago, well ahead of modern humans, who showed up only about 45,000 years ago. But within about 5,000 years of our arrival, the indigenous Neanderthals had...

Hedgehog in space

Your best guess is that the landscape is as inhospitable as it gets: an irregular range of sharp boulders and loose rubble piles strewn among jagged crevasses and deep troughs of dust. But then again, it’s just a guess because no one’s ever actually seen this...

Delivering Genes Across the Blood-Brain Barrier

Caltech biologists have modified a harmless virus in such a way that it can successfully enter the adult mouse brain through the bloodstream and deliver genes to cells of the nervous system. The virus could help researchers map the intricacies of the brain and holds...

White House Puts Spotlight on Earthquake Early-Warning System

Since the late 1970s, Caltech seismologist Tom Heaton, professor of engineering seismology, has been working to develop earthquake early-warning (EEW) systems—networks of ground-based sensors that can send data to users when the earth begins to tremble nearby, giving...
