Don't Mess with Texas is a slogan for a campaign aimed at reducing littering on Texas roadways by the Texas Department of Transportation. The phrase "Don't Mess with Texas" is prominently shown on road signs on major highways, television, radio and in print advertisements. The campaign is credited with reducing litter on Texas highways roughly 72% between 1987 and 1990. The campaign's target market was 18- to 35-year-old males, which was statistically shown to be the most likely to litter. While the slogan was not originally intended to become a statewide cultural phenomenon, it did.

Beyond its immediate role in reducing litter, the slogan has been popularly appropriated by Texans. The phrase has become "an identity statement, a declaration of Texas swagger". Though the origin of the slogan is not well known outside of Texas, it appears on countless items of tourist souvenirs. Since the phrase is a federally registered trademark, the department has tried at times to enforce its trademark rights with cease and desist letters, but has had very limited success. The slogan is the title of the book, Don’t Mess With Texas: The Story Behind the Legend.

"Don't Mess with Texas" has been awarded a plaque on the Madison Avenue Walk of Fame and a place in the Advertising Hall of Fame, a distinction given to only two slogans annually.

"Don't Mess with Texas" is also the official motto of the Virginia-class submarine USS Texas.

In 2011 the result of a public vote for the best "Don't Mess with Texas" ad over the last 25 was revealed, the winner was one created by the Commemorative Air Force (then called the Confederate Air Force). The ad involved the CAF's Boeing B-17 "Sentimental Journey" pursuing and retaliating against a truck from which trash was thrown.

The Granai airstrike, sometimes called the Granai massacre, refers to the killing of approximately 86 to 147 Afghan civilians by an airstrike by a US Air Force B-1 Bomber on May 4, 2009, in the village of Granai (sometimes spelled Garani or Gerani) in Farah Province, south of Herat, Afghanistan.

The United States admitted significant errors were made in carrying out the airstrike, stating "the inability to discern the presence of civilians and avoid and/or minimize accompanying collateral damage resulted in the unintended consequence of civilian casualties".

The Afghan government has said that around 140 civilians were killed, of whom 22 were adult males and 93 were children. Afghanistan's top rights body has said 97 civilians were killed, most of them children. Other estimates range from 86 to 147 civilians killed. An earlier probe by the US military had said that 20–30 civilians were killed along with 60–65 insurgents. A partially released American inquiry stated "no one will ever be able conclusively to determine the number of civilian casualties that occurred". The Australian has said that the airstrike resulted in "one of the highest civilian death tolls from Western military action since foreign forces invaded Afghanistan in 2001".

🔗 Ecology 🔗 Glaciers

Glacier mice are colonies of mosses found on some glaciers and adjacent ecosystems. They are composed of multiple species of moss and can also host other species, such as nematode worms, springtails, and water bears. Although what preconditions are necessary for glacier mice to form has yet to be determined, they have been observed in Alaska, Chile, Greenland, Iceland, Svalbard, Uganda and Venezuela, as well as several Subantarctic islands. In at least some cases, glacier mice apparently reproduce asexually due to the effect of the harsh glacier environment on traditional moss reproduction strategies.

Glacier mice are notable for their movement across the ice, which appears to be non-random, taking the form of herd-like behavior. This movement is as yet unexplained, and does not appear to be solely the product of wind or the direction of a slope.

Ramanujan's lost notebook is the manuscript in which the Indian mathematician Srinivasa Ramanujan recorded the mathematical discoveries of the last year (1919–1920) of his life. Its whereabouts were unknown to all but a few mathematicians until it was rediscovered by George Andrews in 1976, in a box of effects of G. N. Watson stored at the Wren Library at Trinity College, Cambridge. The "notebook" is not a book, but consists of loose and unordered sheets of paper described as "more than one hundred pages written on 138 sides in Ramanujan's distinctive handwriting. The sheets contained over six hundred mathematical formulas listed consecutively without proofs."

George Andrews and Bruce C. Berndt (2005, 2009, 2012, 2013, 2018) have published several books in which they give proofs for Ramanujan's formulas included in the notebook. Berndt says of the notebook's discovery: "The discovery of this 'Lost Notebook' caused roughly as much stir in the mathematical world as the discovery of Beethoven’s tenth symphony would cause in the musical world."

Hi everyone,

I'm baaaaack!

I co-founded Wikipedia long ago. While I was gone for a long time, I did keep abreast what's been going on and how the system works, as a student and critic of Wikipedia and of the internet generally.

But as of fall 2025, I have returned, with the aim of helping Wikipedia in various ways to reform.

Most recently, I have been working on WikiProject Intellectual Diversity. This is not yet an approved WikiProject, but I am confident we will get enough supporters to make our application successful. If you too want Wikipedia to be reformed in ways that will make the project more open and welcoming to those of a more intellectually diverse body of contributors, please join!

For most of 2025, I developed Nine Theses on Wikipedia, which is partly an extended criticism and partly a reform proposal. Unlike much of my previous writing and speaking about Wikipedia over the past 20 years or so, this is not merely negative. It is a realistic plan to make Wikipedia better. I hope you will take it seriously.

All the best,

P.S. Here's what I posted when I left in 2002. Still good advice:

All the best to Wikipedia and Wikipedians. May you continue

• to be open and warmly welcoming, not insular,
• to be focused singlemindedly on writing an encyclopedia, not on Usenet-style debate,
• to recognize and praise the best work, work that is detailed, factual, well-informed, and well-referenced,
• to work to understand what neutrality requires and why it is so essential to and good for this project,

• to treat your fellow productive, well-meaning members of Wikipedia with respect and good will,
• to attract and honor good people who know a lot and can write about it well, and
• to show the door to trolls, vandals, and wiki-anarchists, who if permitted would waste your time and create a poisonous atmosphere here.

🔗 Energy

A black start is the process of restoring an electric power station or a part of an electric grid to operation without relying on the external electric power transmission network to recover from a total or partial shutdown.

Normally, the electric power used within the plant is provided from the station's own generators. If all of the plant's main generators are shut down, station service power is provided by drawing power from the grid through the plant's transmission line. However, during a wide-area outage, off-site power from the grid is not available. In the absence of grid power, a so-called black start needs to be performed to bootstrap the power grid into operation.

To provide a black start, some power stations have small diesel generators, normally called the black start diesel generator (BSDG), which can be used to start larger generators (of several megawatts capacity), which in turn can be used to start the main power station generators. Generating plants using steam turbines require station service power of up to 10% of their capacity for boiler feedwater pumps, boiler forced-draft combustion air blowers, and for fuel preparation. It is uneconomical to provide such a large standby capacity at each station, so black-start power must be provided over designated tie lines from another station. Often hydroelectric power plants are designated as the black-start sources to restore network interconnections. A hydroelectric station needs very little initial power for starting purposes (just enough to open the intake gates and provide excitation current to the generator field coils), and can put a large block of power on line very quickly to allow start-up of fossil-fuel or nuclear stations. Certain types of combustion turbine can be configured for black start, providing another option in places without suitable hydroelectric plants. In 2017, a utility in Southern California successfully demonstrated the use of a battery-based energy-storage system to provide a black start, firing up a combined-cycle gas turbine from an idle state.

🔗 United States 🔗 Elections and Referendums

The Massachusetts "Right to Repair" Initiative, also known as Question 1, appeared on the Massachusetts 2012 general election ballot as an initiated state statute. The Right to Repair proposal was to require vehicle owners and independent repair facilities in Massachusetts to have access to the same vehicle diagnostic and repair information made available to the manufacturers' Massachusetts dealers and authorized repair facilities. The initiative passed with overwhelming voter support on November 6, 2012, with 86% for and 14% against. The measure, originally filed four times with the Massachusetts Attorney General, was filed by Arthur W. Kinsman, and was assigned initiative numbers 11-17.

2019 Ballot Initiative In early 2019 the Massachusetts Legislature submitted bills advocating change to close loopholes associated with wireless transmission of diagnostic information. Advocates supporting an update to the Massachusetts Right to Repair law have announced that the required signatures have been gathered to place Right to Repair on the November 3, 2020 ballot.

🔗 Norway

Norsk Data was a (mini-)computer manufacturer located in Oslo, Norway. Existing from 1967 to 1992, it had its most active period in the years from the early 1970s to the late 1980s. At the company's peak in 1987 it was the second largest company in Norway and employed over 4,500 people.

Throughout its history Norsk Data produced a long string of extremely innovative systems, with a disproportionately large number of world firsts. Some examples of this are the NORD-1, the first minicomputer to have memory paging as a standard option, and the first machine to have floating-point instructions standard, the NORD-5, the world's first 32-bit minicomputer (beating the VAX, often claimed the first, by 6 years)

HeLa (; also Hela or hela) is an immortal cell line used in scientific research. It is the oldest and most commonly used human cell line. The line was derived from cervical cancer cells taken on February 8, 1951 from Henrietta Lacks, a patient who died of cancer on October 4, 1951. The cell line was found to be remarkably durable and prolific, which gives rise to its extensive use in scientific research.

The cells from Lacks's cancerous cervical tumor were taken without her knowledge or consent, which was common practice at the time. Cell biologist George Otto Gey found that they could be kept alive, and developed a cell line. Previously, cells cultured from other human cells would only survive for a few days. Scientists would spend more time trying to keep the cells alive than performing actual research on them. Cells from Lacks' tumor behaved differently. As was custom for Gey's lab assistant, she labeled the culture 'HeLa', the first two letters of the patient's first and last name; this became the name of the cell line.

These were the first human cells grown in a lab that were naturally "immortal", meaning that they do not die after a set number of cell divisions (i.e. cellular senescence). These cells could be used for conducting a multitude of medical experiments—if the cells died, they could simply be discarded and the experiment attempted again on fresh cells from the culture. This represented an enormous boon to medical and biological research, as previously stocks of living cells were limited and took significant effort to culture.

The stable growth of HeLa enabled a researcher at the University of Minnesota hospital to successfully grow polio virus, enabling the development of a vaccine, and by 1952, Jonas Salk developed a vaccine for polio using these cells. To test Salk's new vaccine, the cells were put into mass production in the first-ever cell production factory.

In 1953, HeLa cells were the first human cells successfully cloned and demand for the HeLa cells quickly grew in the nascent biomedical industry. Since the cells' first mass replications, they have been used by scientists in various types of investigations including disease research, gene mapping, effects of toxic substances on organisms, and radiation on humans. Additionally, HeLa cells have been used to test human sensitivity to tape, glue, cosmetics, and many other products.

Scientists have grown an estimated 50 million metric tons of HeLa cells, and there are almost 11,000 patents involving these cells.

The HeLa cell lines are also notorious for invading other cell cultures in laboratory settings. Some have estimated that HeLa cells have contaminated 10–20% of all cell lines currently in use.

Casu martzu (Sardinian pronunciation: [ˈkazu ˈmaɾtsu]; literally 'rotten/putrid cheese'), sometimes spelled casu marzu, and also called casu modde, casu cundídu and casu fràzigu in Sardinian language, is a traditional Sardinian sheep milk cheese that contains live insect larvae (maggots). A variation of the cheese, casgiu merzu, is also produced in some Southern Corsican villages like Sartene.

Derived from pecorino, casu martzu goes beyond typical fermentation to a stage of decomposition, brought about by the digestive action of the larvae of the cheese fly of the Piophilidae family. These larvae are deliberately introduced to the cheese, promoting an advanced level of fermentation and breaking down of the cheese's fats. The texture of the cheese becomes very soft, with some liquid (called làgrima, Sardinian for "teardrop") seeping out. The larvae themselves appear as translucent white worms, roughly 8 mm (0.3 in) long.
