Chinese Scientists Bioengineering
Plants With Firefly Genes to Glow, in Effort to Light Cities at Night
(Source: Futurism)
A shortcut to sprucing up any dreary urban locale is by throwing in
some beautiful greenery. Now, Chinese scientists have unveiled new
genetically engineered plants that can glow in the dark, which they say
could be a compelling draw for tourism and even help light cities at
night.
The bioluminescent flora were created by splicing genes from fireflies
and glowing fungi into the plant cells, allowing them to emit a soft
glow. Using these techniques, the scientists have modified over twenty
species to glow in the dark, including orchids, sunflowers, and
chrysanthemums. Editor's
Note: Researchers at UF are doing similar things for future
space-based greenhouses, allowing plants to express through light when
they are distressed. (4/4)

How Much More Elbow Room Does Artemis
II's Orion Have Than Apollo? (Source: USA Today)
The Orion spacecraft that’s taking the four Artemis II astronauts
around the moon and back is the largest crewed capsule ever sent beyond
low Earth orbit – with habitable space roughly equal to that of two
minivans combined, NASA says. With an interior space of 330 cubic feet,
is nearly 60% larger than its Apollo command module predecessor and
much bigger than the early Mercury and Gemini capsules of the 1960s.
That's a long way from the days of Mercury astronauts, described by
“The Right Stuff” author Tom Wolfe as “spam in a can.” (4/5)
Gen Z Fled California for Texas and

Towns (Source: Fortune)
It started with a pandemic exodus, as workers moved to be closer to
their families or to pursue a different lifestyle; then they steadily
drifted toward Texas and Florida, where jobs were plentiful and rent
was more manageable. A new report from real estate and investment
management firm JLL shows there’s a third chapter in San Francisco’s
migration script in which younger generations are moving to “welcomer
cities” like Nashville and Orlando.
JLL now defines Nashville and Orlando as welcomers because they still
offer plenty of corporate job opportunities, but are more affordable
than large cities. These cities are now legitimate contenders in the
innovation economy, according to JLL, which tracks talent migration,
office market dynamics, and corporate investment across 135 cities
globally. It started with a pandemic exodus, as workers moved to be
closer to their families or to pursue a different lifestyle; then they

Especially in the past few years, Gen Z has been flocking to more
affordable cities just to get by during the cost-of-living crisis.
Aside from places like Texas and Florida, many have made moves to the
Midwest, where homes are about 30% cheaper than on the coasts.
Apartments.com shows the cost of living in San Francisco is 80.6%
higher than in Orlando, and housing prices are 226.2% higher. (4/2)

Do Gravitational Waves Redshift Like
Light Does? (Source: Big Think)
The relative motion of the emitting source and the receiving observer,
the changes in the gravitational field that the traveling signal
experiences during its journey, and the effects of either expansion or
contraction of the spacetime through which the signal travels. These
three effects can lead to redshifts or blueshifts, depending on which
direction they occur in, and it was long expected that they’d affect
all waves, not just light waves, in a similar fashion.
Any effect that causes a shift in the frequency of electromagnetic
waves due to an interaction with matter — whether neutral matter,
ionized matter, or an electromagnetic field generated by matter —
cannot also apply to gravitational waves. As their name implies,
gravitational waves (or gravitational radiation) is a purely
gravitational phenomenon, and so it should only be subject to purely
gravitational effects.
There's no wavelength-dependent absorption, emission, or scattering for
gravitational waves, and no deflection, reflection, or refraction of
gravitational waves as they pass through a medium. For gravitational
waves, if the inspiral-and-merger of black holes is from a system that
recedes from you, the wavelength that you’ll see is going to be
redshifted by that exact factor — dictated by the Doppler shift’s
velocity — of the relative motion of that source to you, the observer.

Aerial robotic platforms (aerobots) that can operate for years may be
an ideal choice for exploring Earth's "Sister Planet." While prototypes
have been built in response to NASA's strategic plans, these designs
lack a method for replenishing buoyant gases, limiting their lifetimes.
According to a new proposal led by MIT researchers, In-Situ Resource
Utilization (ISRU) could extend the lifetime of aerobots by using
electrolysis to convert atmospheric carbon dioxide (CO2) into buoyant
gas products and an energy source. (4/3)
African Market for Satellite Services
Offers Pent Up Demand (Source: Via Satellite)
With a large landmass of 11.7 million square miles, Africa has been a
challenging place to set up satellite services. But that is changing.
As of September, 2025, more than 21 African countries have established
space programs and 18 have launched at least one satellite, according
to the Africa Center for Strategic Studies. Now the real work of
digital inclusion, enterprise application, and national development
connecting millions of Africans begins, industry experts shared during
SATShow Week.
Africa is one of the fastest growing satellite markets in the world
with limited terrestrial infrastructure and growing demand for
connectivity. African nations and companies have launched a combined
total of 65 satellites, with over 120 additional satellites in
development and expected to be launched by 2030. (4/3)

Why Is NASA Bothering To Go Back to
the Moon if We’ve Already Been There? (Source: Ars Technica)
The first time NASA launched humans toward the Moon, in December 1968,
the United States was a deeply fractured nation. The historic flight of
three people into the unknown brought a measure of solace to a country
riven by assassinations, riots, political discord, and a deeply
unpopular foreign war. If history does not repeat itself, it certainly
rhymes. Today, four humans are on the way to the Moon, Reid Wiseman,
Victor Glover, Christina Koch, and Jeremy Hansen. They do so, once
again, amid a troubled world. Will Artemis II have a similar impact?
Does it even matter?
Artemis II was not a global event. The world of today is, of course,
incredibly different from that of the 1960s, especially the landscape
of media competing for public attention. Just three US television
networks graced the airwaves then, compared to hundreds today and a
bazillion more online through viewing options like YouTube and social
media. And increasingly, younger generations are as interested in
creating content as they are in consuming it. The world population in
1968 was about 3.5 billion people, or a little less than half of
today’s. Yet an estimated one-quarter of them watched broadcasts from
the Moon. (4/2)
Insurance is Commercial Space
Nuclear’s Biggest Headache (Source: Payload)
There are no good neighbors for the commercial space nuclear power
business. Lots of challenges face commercial space nuclear missions—but
experts at an industry seminar on Thursday only called one a “show
stopper”—insurance. Entrepreneurs believe they can safely launch
radioactive material into orbit without creating an accident of atomic
proportions, but insurance companies are still balking at the word
“nuclear,” according to company leaders.
“Insurance is a fundamentally conservative and reactionary industry,”
said Stewart Forbes, an energy attorney with Hogan Lovells. “People
still think Chernobyl or Fukushima or Three Mile Island, but that’s not
the world we live in anymore.”
Nuclear reactors would remain inert, with controls engaged to keep them
from going critical, until they enter orbit. The real—but small—risk
would be a reactor that somehow re-enters Earth’s atmosphere after
activation. (4/3)

From Artemis to ULA, Space Force Has
Hands Full with 6 Different Rockets this Year (Source: Orlando
Sentinel)
NASA’s Artemis II mission got the limelight this week, but U.S. Space
Force has an arsenal of other space-bound hardware muscling onto
Florida’s launch pads this year. This year’s schedule from either
Kennedy Space Center or Cape Canaveral Space Force Station already
features six different rockets. Vying for many of the same support
assets are two from SpaceX, two from United Launch Alliance, one from
Blue Origin plus NASA’s Space Launch System rocket.
Those launches require a juggling act, as they all need some of the
same supplies, facilities and staff, said Space Launch Delta 45
commander Col. Brian Chatman. For example, many of the spacecraft
operators want gaseous nitrogen (GN2) on hand during launches. The
inert gas keeps their rocket hardware safe by pushing out more volatile
propellants in the case of a scrub. A lot of that comes from a plant on
Merritt Island, and NASA got first dibs on it last week. (4/4)
