Staying safe in the sun includes more than sunscreen
W
e have all been encour-
aged to apply sunscreen
products to ourselves
and family members before sig-
nifi cant sun exposure. Protection
from the sun’s UV rays is import-
ant to help prevent some skin can-
cers. But have you ever read the
ingredients on your sunscreen bot-
tle? You will likely fi nd one or
more of the following ingredients:
avobenzone, oxybenzone, ecam-
sule, and octocrylene. It has been
known since the 1990s that these
ingredients are absorbed into the
bloodstream, but the long term
effects are still unknown. There is
concern that some of these chem-
icals may cause endocrine, repro-
ductive, developmental and can-
cer-related problems. In February

of this year, the FDA announced
that it is creating a new set of rules
and regulations around sunscreens
which will be released in Novem-
ber 2019.
The lack of safety informa-
tion regarding common sunscreen
products was highlighted in a May
2019 article in The Journal of the
American Medical Association.
Researchers enrolled 24 adults who
applied the recommended amount
of sunscreen (spray, lotion and
creams) to 75% of their exposed
skin four times a day. Research-
ers then measured the levels of
sunscreen chemicals in the blood
every day for seven days. The rec-
ommended distribution of sun-
screen is equivalent to a quarter
teaspoon applied to one’s face.
The current FDA recommended
blood level for these chemicals is
less than 0.5 nanogram per mil-
liliter (ng/mL). After one day of
application, regardless of the type
of sunscreen, blood levels for all
the ingredients were over 1ng/mL.
Oxybenzone levels were the high-
est at 34.4 ng/mL after 7 days of
using sunscreen spray. Overall, the
blood levels of the chemicals far
exceeded the recommended con-
centration. While this was a small
study, it does raise important ques-
tions about the safety of these
products.
The FDA uses the term “gener-
ally regarded as safe and effective”
or “GRASE” to designate product
safety. Only zinc and titanium are
designated as “GRASE” for sun
protectants at this time. Zinc and
titanium are larger molecules that
stay on the surface of the skin and
do not absorb into the bloodstream.
There are 12 other common chem-
icals in sunscreens, including those
in the study above, that are now
under the designation of “insuffi -
cient evidence of GRASE.” PABA
and trolamine are rarely seen on
the shelves anymore, and they are
considered “not GRASE.”
Protection from the sun’s harm-
ful UV rays continues to be para-
mount. There is not enough research
at this point to make a conclusion
on the long term safety of these
products. There will be more to
come about the safety of sunscreen
and different sunscreen products in
the future. Note that many of these
chemicals can be found in chap-
sticks, cosmetics and lotions. In the
meantime, avoidance of sun during
the hours of 10 a.m. to 2 p.m.,
shade, clothing, and zinc and tita-
nium sunscreens are the safest ways
to go. See you at the beach!

NASA will send quadracopter to Titan to search for methane sources
NASA
Paul Voosen
The siren call of Titan
could not be ignored.
NASA’s next billion-dol-
lar mission, called Drag-
onfl y, will be an innovative
quadcopter to explore Titan,
Saturn’s largest moon, the
agency announced today.
The craft will soar and
hover over the icy moon’s
surface—and land on it—in
a search for the conditions
and chemistry that could
foster life.
The mission—led by
Elizabeth “Zibi” Turtle, a
planetary scientist at the
Johns Hopkins Univer-
sity Applied Physics Lab-
oratory (APL) in Laurel,
Maryland, and also man-
aged by APL—will launch
in 2026. It represents a cal-
culated risk for the agency,
embracing a new paradigm
of robotic exploration to
be used on a distant moon.
“Titan is unlike any other
place in the solar system,
and Dragonfl y is like no
other mission,” said Thomas
Zurbuchen, NASA’s asso-
ciate administrator for sci-
ence in Washington, D.C.,
while announcing the mis-
sion’s selection. “The sci-
ence is compelling. It’s the
right time to do it.”
Titan is veiled by a nitro-
gen atmosphere and larger
than Mercury. It is thought
to harbor a liquid ocean
beneath its frozen crust of
water ice. NASA’s Cas-
sini spacecraft studied Titan
during its historic campaign,
and, in 2005, dropped the
short-lived Huygens probe
into Titan’s atmosphere.
The surface it saw had
many geologic features sim-
ilar to those found on Earth,
including plateaus, dune-

fi lled deserts, and, at its
poles, liquid seas and rivers.
But on Titan, where tem-
peratures average a frigid
94 K, the “rocks” are made
T HE B OOKLOFT
of water ice and the seas are
fi lled with ethane and meth-
ane, hydrocarbons that are
gases on Earth. The moon’s
stew of organic molecules
and water, many scientists
believe, could have resulted
in reactions to create amino
acids and the bases used to
build DNA’s double helix.
It’s as if Titan has been con-
ducting experiments on life
formation for millions of
years, Turtle says. “Dragon-
fl y is designed to go pick up
the results of those experi-
ments and study them.”

ing selection, adds Lindy
Elkins-Tanton, a planetary
scientist at Arizona State
University in Tempe and
principal investigator of
Psyche, NASA’s mission to
a metallic asteroid. “Titan
might truly be the cradle
for some kind of life—and
whether life has emerged
or not, Titan’s hydrocar-
bon rivers and lakes, and its
hydrocarbon snow, makes
it one of the most fantasy-
like landscapes in our solar
system.”
Given Titan’s complex
surface, a lander at a sin-
gle site would not be able to
say much about the moon’s
chemistry. Dragonfl y lever-
ages the advances in com-
puting and aircraft design
that have led to the explo-
sion of hovering drones on
Earth. It will carry eight
rotor blades, on the top and
bottom of each of four arms.
It is, in effect, a movable
lander, capable of shunting
kilometers between sam-
pling sites every 16 Earth
days. Titan’s dense air and
low gravity will allow the
300-kilogram, sedan-size
copter, which will be pow-
ered by a radioactive gener-
ator, to hover with 38 times
less power than needed on
Earth.
