Scientists Are Turning Mosquitoes โ€œTransโ€ So They Can Fight Malaria

New LGBTQ+ insect just dropped. (From A: But is this really trans?)

Byย Abby Monteil October 8, 2024

From gay polyamorous flamingos to a โ€œhalf-male, half-female birdโ€ sighting, Mother Nature has proven that sheโ€™s pretty damn queer. But sometimes, scientists like to get in on the fun, too. It turns out that some are even using their talents to engineer โ€œtransโ€ mosquitoes (yes, really).

On October 5, the X account @Rainmaker1973 shared a video of a female mosquito attempting to bite a human hand. However, its blood-sucking attempts are thwarted because its proboscis โ€” aka its needle-like mouth โ€” could not break through the skin.

โ€œUsing the CRISPR technique, itโ€™s possible to genetically modify mosquitoes by disabling a gene in females, so that their proboscis turns male, making them unable to pierce human skin,โ€ @Rainmaker1973 explained.

Before we go further, a quick science lesson: According to the National Human Genome Research Institute, Clustered Regularly Interspaced Short Palindromic Repeats, or CRISPR, is a technology that allows scientists to selectively modify DNA.

So why use this technology on mosquitoes? Well, malaria, which kills more than 600,000 people per year, is transmitted to humans by female mosquitoes belonging to the genus Anopheles, which, per the National Institute of Allergy and Infectious Diseases, encompasses between 30 and 40 mosquito species. According to a 2018 study in the journal Nature Biotechnology, using CRISPR technology on female mosquitoes resulted in egg production reaching the point of โ€œtotal population collapseโ€ within 7 to 11 generations. In other words, this technique allows scientists to not only ensure that female mosquitoes carrying malaria canโ€™t spread the disease to humans, but that they canโ€™t reproduce in general. This CRISPR-enabled gene editing is just one of several techniques that researchers have used to fight the spread of malaria in humans.

So, sure, in a manner of speaking, scientists are doing their best to curb the spread of malaria by making some mosquitoes โ€œtrans.โ€ In addition to being a genetic achievement, @Rainmaker1973โ€™s viral video sharing the news also unsurprisingly inspired some excellent tweets. (see on the page)

She strokin tryna wake it up OMGโ€ฆ hrt no joke,โ€ one X user tweeted.

โ€œMosquitoes pissing me off so I took out my crispr and gave them gender dysphoria,โ€ another joked.

The past few years have introduced no shortage of queer bugs, from fruit flies who were potentially turned gay by air pollution to cicadas who became hypersexual zombies after being infected with a sexually transmitted fungus. Whatโ€™s a few more trans mosquitoes?

The Limited Test Ban Treatyโ€”banning nuclear tests in the oceans, in the atmosphere, and in outer spaceโ€”went into effect. The nuclear powers of the timeโ€”the United States, Great Britain, and the Soviet Unionโ€”had signed the treaty earlier in the year.
In 1957, Nobel Prize-winner (Chemistry) Linus Pauling drafted the Scientists’ Bomb-Test Appeal with two colleagues, Barry Commoner and Ted Condon, eventually gaining the support of 11,000 scientists from 49 countries for an end to the testing of nuclear weapons. These included Bertrand Russell, Albert Einstein, and Albert Schweitzer.


Linus Pauling
Pauling then took the resolution to Dag Hammarskjรถld, then Secretary-General of the United Nations, and sent copies to both President John F. Kennedy and Soviet Premier Nikita Kruschev. The final treaty had many similarities to Paulingโ€™s draft. It went into effect the same day as the announcement of Paulingโ€™s second Nobel Prize, this time for Peace.

DISCUSSION AND OUTLOOK
----------------------
At 800 PM EDT (0000 UTC), the center of Hurricane Milton was located
near latitude 27.2 North, longitude 82.8 West. Milton is moving
toward the east-northeast near 15 mph (24 km/h), and this general
motion is expected to continue through Thursday, followed by a turn
toward the east on Friday. On the forecast track, the center of
Milton will make landfall just south of the Tampa Bay region
within the next hour or two, and then move across the central part
of the Florida peninsula overnight, and emerge off the east coast of
Florida on Thursday.

Maximum sustained winds are near 120 mph (195 km/h) with higher
gusts. Milton is a category 3 hurricane on the Saffir-Simpson
Hurricane Wind Scale. Little change in strength is likely
until landfall, and Milton is expected to remain a hurricane
while it moves across central Florida through Thursday. The system
is forecast to weaken over the western Atlantic and become
extratropical by Thursday night.

Hurricane-force winds extend outward up to 35 miles (55 km) from
the center and tropical-storm-force winds extend outward up to 255
miles (405 km). A sustained wind of 54 mph (87 km/h) and a gust of
96 mph (154 km/h) was recently reported at the Sarasota-Bradenton
International Airport. A C-MAN Station in Venice, Florida recently
reported a sustained wind of 71 mph (115 km/h) with a gust to 90
mph (145 km/h).

The minimum central pressure estimated from Hurricane Hunter
aircraft observations is 954 mb (28.17 inches).


HAZARDS AFFECTING LAND
----------------------
Key Messages for Milton can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDAT4 and WMO header WTNT44 KNHC
and on the web at hurricanes.gov/text/MIATCDAT4.shtml

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Anna Maria Island, FL to Boca Grande, FL...9-13 ft
Anclote River, FL to Anna Maria Island, FL...6-9 ft
Tampa Bay...6-9 ft
Boca Grande, FL to Bonita Beach, FL...8-12 ft
Charlotte Harbor...8-12 ft
Bonita Beach, FL to Chokoloskee, FL...5-8 ft
Chokoloskee, FL to Flamingo, FL...3-5 ft
Sebastian Inlet, FL to Altamaha Sound, GA...3-5 ft
Yankeetown, FL to Anclote River, FL...2-4 ft
Dry Tortugas...2-4 ft
St. Johns River...2-4 ft

The deepest water will occur along the immediate coast near and to
the south of the landfall location, where the surge will be
accompanied by large and dangerous waves. Surge-related flooding
depends on the relative timing of the surge and the tidal cycle,
and can vary greatly over short distances. For information
specific to your area, please see products issued by your local
National Weather Service forecast office.

For a complete depiction of areas at risk of storm surge
inundation, please see the National Weather Service Peak Storm
Surge Graphic, available at
hurricanes.gov/graphics_at4.shtml?peakSurge.

RAINFALL: Rainfall amounts of 6 to 12 inches, with localized totals
up to 18 inches, are expected across central to northern portions of
the Florida Peninsula through Thursday. This rainfall brings the
risk of catastrophic and life-threatening flash and urban flooding,
along with moderate to major river flooding.

For a complete depiction of forecast rainfall associated with
Hurricane Milton, please see the National Weather Service Storm
Total Rainfall Graphic, available at
hurricanes.gov/graphics_at4.shtml?rainqpf and the Flash Flood Risk
graphic at hurricanes.gov/graphics_at4.shtml?ero.

WIND: Hurricane conditions are occurring within the hurricane
warning area and will spread east-northeastward across the Florida
peninsula overnight. Hurricane conditions are possible in the
hurricane watch area tonight and on Thursday. Tropical storm
conditions are occurring along the west coast of Florida and are
forecast to spread across the peninsula and reach the east coast
tonight. Tropical storm conditions are expected to begin in the
warning area along the Georgia and South Carolina coast on Thursday.

Tropical storm conditions are expected in portions of the
northwestern Bahamas on Thursday.

TORNADOES: Several tornadoes, possibly including a few strong
tornadoes, are likely this evening and tonight across parts of
central Florida.

SURF: Swells generated by Milton are expected to continue to affect
much of the Gulf Coast and will increase along the southeastern U.S.
coast during the next day or two. These swells are likely to cause
life-threatening surf and rip current conditions. Please consult
products from your local weather office.

Space-made next-gen optic fibres touch back down to Earth

October 8, 2024 Imma Perfetto

Next-generation optical fibre manufactured in microgravity aboard the International Space Station has been returned safely to Earth.

Scientists at Adelaide University in South Australia are now comparing the fibres to otherwise identical Earth-made counterparts to confirm whether the space-made product is superior.

Itโ€™s thought likely that it is, but the results wonโ€™t be known for a couple of months.

The research has already delivered some interesting results: โ€œSeven of the draws went beyond 700 meters, showcasing that it is possible to produce commercial lengths of fibre in space,โ€ says Rob Loughan, CEO of the company that designed the fibre drawing device, Flawless Photonics.

โ€œThe longest draw went above 1,141 meters, setting a record for the longest fibre manufactured in space.โ€

The fibres were made of ZBLAN glass, a substance which has the potential to transmit light 20 times further than traditional silica-based fibre-optic cables.

In an optical fibre, light becomes dimmer and dimmer as it travels along the fibre. Therefore, for example, submarine fibre optics cables require amplifiers about every 100km to boost the light signal to allow it to be transmitted over long distances.

A ZBLAN optical fibre could increase distances between amplifiers, from every 100 km for silica fibres to every 2,000 km.

But this isnโ€™t feasible yet. In practice, ZBLAN fibres perform about 10 times worse than the best silica fibres because the fabrication process introduces defects and impurities, which lower its efficiency at transmitting light.

Professor Heike Ebendorff-Heidepriem, and her team at the University of Adelaideโ€™s Australian National Fabrication Facilityโ€™s (ANFF) are trying to solve the problem of enhanced impurities and defects in current ZBLAN glass fibres.

โ€œThe purity of the glass depends on the purity of the raw material, and it is challenging to make highly pure solid raw materials,โ€ says Ebendorff-Heidepriem. The team is trying to completely remove one of the main reasons the defects form: gravity.

โ€œGravity here on Earth causes convection โ€ฆ If you heat up something on a hot plate, the liquid is hot at the bottom. That makes the density of the liquid at the bottom become lower, which moves this portion of the liquid up, at the top the liquid becomes cooler, making the density higher, therefore gravity pulls it down, and so onโ€ she explains.

Ebendorff-Heidepriem partnered with Flawless Photonics which designed and operates a fibre drawing device that squeezed all the necessary technology into a 0.8m-long box for the ISS.

In June, the more than 11km of fibre returned to Earth, intact. Now, work is underway at the University of Adelaide and at 5 other organisations around the world to determine how much of an impact gravity has on ZBLANโ€™s ability to transmit light. They are hoping to complete their analysis by December this year.

โ€œWe will see: is it better? Is it worse? Is it the same? And no matter what result we get, I think the biggest outcome is already achieved โ€“ we can make commercial lengths of optical fibres in space.โ€

Q&A: How the UK became the first G7 country to phase out coal power

https://interactive.carbonbrief.org/coal-phaseout-UK/

Snippet:

By Molly Lempriere and Simon Evans

26 September 2024


The UKโ€™s last coal-fired power plant, Ratcliffe-on-Soar in Nottinghamshire, will close this month, ending a 142-year era of burning coal to generate electricity.

The UKโ€™s coal-power phaseout is internationally significant.

It is the first major economy โ€“ and first G7 member โ€“ to achieve this milestone. It also opened the worldโ€™s first coal-fired power station in 1882, on Londonโ€™s Holborn Viaduct.

From 1882 until Ratcliffeโ€™s closure, the UKโ€™s coal plants will have burned through 4.6bn tonnes of coal and emitted 10.4bn tonnes of carbon dioxide (CO2) โ€“ more than most countries have ever produced from all sources, Carbon Brief analysis shows.

The UKโ€™s coal-power phaseout will help push overall coal demand to levels not seen since the 1600s.

The phaseout was built on four key elements.

First, the availability of alternative electricity sources, sufficient to meet and exceed rising demand.

Second, bringing the construction of new coal capacity to an end.

Third, pricing externalities, such as air pollution and carbon dioxide (CO2), thus tipping the economic scales in favour of alternatives.

Fourth, the government setting a clear phaseout timeline a decade in advance, giving the power sector time to react and plan ahead.

The UKโ€™s experience, set out and explored in depth in this article, demonstrates that rapid coal phaseouts are possible โ€“ and could be replicated internationally.

As the UK aims to fully decarbonise its power sector by 2030, it has the challenge โ€“ and opportunity โ€“ of trying to build another case study for successful climate action.

(I’ve been interested in stemming light pollution for a few years, now. I like this progress. -A)

The making of Australiaโ€™s first Dark Sky Community atย Carrickalinga

Sharolyn AndersonUniversity of South Australia

In a world increasingly illuminated by artificial light, the beautiful night skies of a small coastal town in South Australia have attracted international recognition. Carrickalinga on the Fleurieu Peninsula is Australiaโ€™s first official Dark Sky Community. The title rewards a dedicated community effort to combat light pollution and preserve the natural environment at night.

The journey began three years ago when I was a PhD candidate at the Australian National University, working on the value of night skies. I was a regular visitor to Carrickalinga, but this time conversations at a picnic one evening turned to the clarity and brilliance of the stars. I was inspired to work with the locals to nominate Carrickalinga as a โ€œDark Sky Placeโ€.

My recent research suggests restoring dark skies would be worth US$3.4 trillion (A$5.16 trillion) to the world, annually. Thatโ€™s largely because light pollution is disrupting nocturnal pollinators, altering predator-prey interactions, and changing the behaviours of nocturnal species.

Light pollution has detrimental effects on wildlife, human health, and ecosystem functions and services. But there are simple solutions. By embracing responsible lighting practices, everyone can contribute to a healthier future in which the wonders of the night sky are accessible to all.

Understanding light pollution

Light pollution refers to human alteration of outdoor light levels. Excessive or misdirected artificial light brightens the night sky, diminishing our ability to see stars.

Research shows the problem is getting worse. Light pollution increased by 7โ€“10% a year from 2011 to 2022. More than a third of people on Earth cannot see the Milky Way.

Light pollution not only affects our view of the cosmos, but also wastes energy and money, contributes to climate change and has significant repercussions for both ecological and human health.

Nocturnal animals such as bats and certain birds rely on darkness to navigate and find food. Insects, crucial for pollination and as a food source for other wildlife, are also affected. Artificial light at night is contributing to their decline.

In humans, studies have shown artificial light interferes with circadian rhythms, leading to sleep disorders and other health issues.

The global Dark Sky movement

DarkSky International, formerly known as the International Dark Sky Association, is a global network of volunteers combating light pollution. The non-profit organisation established in 1988 is based in Tuscon, Arizona in the United States. But more than 193,000 people across more than 70 countries are involved, including astronomers, environmental scientists and the public.

The International Dark Sky Places Program was born in 2001 when Flagstaff, Arizona was named the first International Dark Sky City. Now the program certifies five types of Dark Sky Places: sanctuaries, reserves, parks, communities, and urban night sky.

DarkSky says the aim is to โ€œpreserve and protect the nighttime environment and our heritage of dark skies through environmentally responsible outdoor lightingโ€. It recognises places that demonstrate a commitment to reducing light pollution through public education, policy, and promoting responsible lighting practices.

There are now well over 200 Dark Sky Places across the globe. This covers more than 160,000 square kilometres in 22 countries on six continents.

Australiaโ€™s Dark Sky Places

Australia is home to several Dark Sky Places, each recognised for their exceptional night skies and dedication to reducing light pollution. These include:

1. Warrumbungle National Park (2016) โ€“ Australiaโ€™s first Dark Sky Park, near Coonabarabran in west-central New South Wales.

2. The Jump-Up (2019) โ€“ Dark Sky Sanctuary in Winton, western Queensland

3. River Murray (2019) โ€“ Dark Sky Reserve, including parts of South Australiaโ€™s Riverland

4. Arkaroola Wilderness Sanctuary (2023) โ€“ Dark Sky Sanctuary, northern Flinders Ranges, South Australia

5. Carrickalinga (2024) โ€“ Australiaโ€™s first Dark Sky Community, Fleurieu Peninsula, South Australia

6. Palm Beach Headland (2024) โ€“ Australiaโ€™s first Urban Night Sky Place, outer Sydney, New South Wales.

Our journey in Carrickalinga

Since 2021, the Carrickalinga community has worked tirelessly towards achieving International Dark Sky Community certification. The journey involved several key initiatives:

  • Sky Quality Metering Program: regular measurements of sky brightness to monitor light pollution levels
  • Community engagement: presentations to community groups and the district council to raise awareness about light pollution, information stalls at local markets, community consultation process (led by the District Council of Yankalilla)
  • Educational materials: printed flyers,ย video, and a โ€œStar Partyโ€ including a presentation on First Nations cosmology
  • Policy development: collaboration with the district council to create a lighting policy including public lighting design that complies with both Australian standards and DarkSky requirements.

Carrickalinga is currently upgrading existing public lighting to reduce light pollution. This will involve a new lighting design plan that reduces correlated colour temperature, ensuring shielded downward-facing lights minimise skyglow, glare and light trespass.

Reducing light pollution by upgrading lighting fixtures does not compromise safety. Dark sky does not mean dark ground.

Light pollution has become such a problem because our lights are unnecessarily bright and poorly designed. Fixing the problem simply involves changing the colour from white to amber, shielding and targeting lights so they do not shine upwards and outwards, and reducing wattage where it is surplus to requirements for peopleโ€™s safety.

How you can help

Achieving and maintaining dark sky status is not difficult but it does require ongoing community effort. Here are the five principles for responsible outdoor lighting, which apply equally to domestic as well as public lighting:

  • Useful โ€“ use light only if it is needed and has a clear purpose
  • Targeted โ€“ direct light so it falls only where it is needed
  • Low light levels โ€“ light should be no brighter than necessary
  • Controlled โ€“ use light only when it is needed
  • Warm colours โ€“ use warm coloured lights wherever possible and avoid short-wavelength (blueโ€“violet) light.

An inspirational journey

Achieving International Dark Sky Community status was a significant achievement in preserving the natural night environment and educating the local community about light pollution. This accomplishment demonstrates the power of community action and serves as a model for others.

By protecting our night skies, we safeguard a vital part of our natural and cultural heritage and also promote healthier ecosystems and communities. Carrickalingaโ€™s journey serves as an inspiring example of what can be achieved through collective effort and dedication to preserving our planetโ€™s natural beauty.

I would like to acknowledge the enormous contribution of Carrickalinga Dark Sky Community volunteer Sheryn Pitman, who works for Green Adelaide in the South Australian Department for Environment and Water, and helped write this article.
