To fight back
against various forms of counterfeiting--especially counterfeit
drugs--researchers at the University of Michigan and in South Korea have
developed a way to make labels that change when you breathe on them,
revealing a hidden image. The labels work because an array of tiny
pillars on the top of a surface effectively hides images that are
written on the material beneath; the hidden images appear when the
pillars trap moisture. (Posted on

Researchers from
UC Berkeley and MIT are developing computer algorithms to compensate for
an individual's visual impairment--and are creating vision-correcting
displays that enable users to see text and images clearly, without
wearing eyeglasses or contact lenses. The technology could
potentially help hundreds of millions of people who currently need
corrective lenses to use their smartphones, tablets, and computers; the
displays could also, one day, aid people with more-complex visual
problems that can't be corrected by eyeglasses. (Posted on

Scientists at the
University of Illinois attached RFID tags to hundreds of individual
honeybees, and tracked them for several weeks. They found that
some foraging bees are much busier than others--and that, if those busy

Researchers from
UC Davis have found that--contrary to previous assumptions--preschoolers
are able to both gauge the strength of their memories, and make
decisions based on their self-assessments. The research involved
investigating whether kids could assess their confidence in their
memories, and then use those assessments in deciding whether to exclude
answers that they had generated but were unsure of when given the
option. (Posted on August 14th.)
The first
preclinical study of a new anti-cancer technology has found that a novel
combination of existing clinical treatments can instantaneously detect
and kill only cancer cells--often by blowing them apart--without harming

A new type of
supercapacitor developed by engineers at Vanderbilt stores electricity
by assembling electrically charged ions on the surface of a porous
material--instead of storing it in chemical reactions, the way that
batteries do. As a result, they can charge and discharge in
minutes, instead of hours--and can operate for millions of cycles,
instead of thousands of cycles like batteries. (Posted on June 18th.)
Complex-networks
researchers at Indiana University have developed a tool that helps
anyone determine whether a Twitter account is operated by a human or,
instead, by an automated software application known as a "social bot":

Exposing leafy
vegetables that are grown during extended spaceflight to a few bright
pulses of light each day could increase the amount of eye-protecting
nutrients that are produced by the plants--according to researchers at
CU-Boulder. Current research into space gardening tends to focus
on getting the plants to grow as large as possible, as quickly as
possible, by providing optimal light, water, and fertilizer; however,
the conditions that are ideal for producing biomass are not necessarily
ideal for the production of many nutrients. (Originally posted on

Researchers at the
University of Washington and the University of Connecticut find that
what spurs early language development isn't so much the quantity of
words that a baby hears as the style of speech and social context in
which speech occurs. They measured parents' use of a regular
speaking voice, versus an exaggerated, animated, "baby talk" style--and
whether speech occurred one-on-one between parent and child, or in group
settings. (Posted on

A study on infant
cognition at the University of Chicago has found that--even before
babies have language skills, or much information about social
structures--they can infer whether others are likely to be friends, by

Birds and other
animals change their behavior in response to manmade noise.
However, research conducted by the National Evolutionary Synthesis
Center finds that such clamor doesn't just affect them: Because
many animals also pollinate plants or disperse their seeds, human noise
can also have ripple effects on plants.

Wetland
restoration is a billion-dollar-a-year industry in the U.S. that aims to
create ecosystems similar to those that disappeared over the past
century. However, a new analysis of restoration projects shows
that restored wetlands seldom reach the quality of a natural wetland.

Researchers have
developed a system that taps into photosynthetic processes to produce
efficient and inexpensive energy. Specifically, the system
improves the efficiency of generating electric power by using molecular
structures that were extracted from plants--which has the potential to
make "green" electricity dramatically cheaper and easier.

Predictions of the
loss of animal and plant diversity around the world are common under
models of future climate change. But, a new study by researchers
at both the University of Connecticut and the University of Washington
shows that--because these climate models don't account for species
competition and movement--they could grossly underestimate future
extinctions.

An NSF-sponsored
study in Chicago-area communities where neighborhood evacuations are
likely due to large amounts of toxic materials that are transported
nearby found that most respondents felt that the evacuation of New
Orleans residents to the Superdome after Hurricane Katrina was a
"failure"--and that this opinion has shaped their willingness to accept
shelter, if offered, in an emergency evacuation.

Researchers at the University of Chicago
have found that preschool children who hear their parents describe the
size and shape of objects--and then use those words themselves--perform
better on tests of their spatial skills. The study is the first to
show that learning to use a wide range of spatial words predicts
children's later spatial thinking--which, in turn, is important in
mathematics, science, and technology.
