White ants; vacations in the mud

Slavery by Ants Is Self-Destructive
“The institution of slavery is not unique to human societies. No fewer than 35 species of ants depend to some extent on slave labor for their existence. The techniques by which they raid other ant colonies to strengthen their labor force rank among the most sophisticated behavior patterns found in the insect world. Most of the slave-making species are so specialized as raiders that they starve to death if deprived of their slaves. Together they display an evolutionary descent that begins with casual raiding by otherwise free-living colonies, passes through the development of full-blown warrior societies and ends with such degeneration that the workers can no longer even conduct raids. —Edward O. Wilson”
Tornado Outbreak Largest on Record
“During the spring and early summer tornadoes are likely to occur between the Gulf of Mexico and Lake Ontario. On April 3 of last year conditions were right. The first tornado struck at 1:10 P.M. By 5:20 A.M. the next day a total of 148 tornadoes had swept across the countryside and cities from Laurel, Miss., to Windsor, Ont., killing 315 people and injuring 5,484. In terms of sheer scope and the number of storms, it was the largest tornado outbreak on record. Immediately after, Theodore Fujita of the University of Chicago and his colleagues organized aerial and ground surveys. Fujita and his co-workers found that 74 percent of the fatalities occurred in houses and buildings, 17 percent in mobile homes, 6 percent in automobiles and 3 percent among people en route to shelter.”

Vacation Fun with Mud Dwellers
“The trouble with vacations is that they have a way of being just what their name implies: too vacant. Few human experiences are worse than that of the individual who finds themselves sitting around in the country or at the seashore with 24 hours a day on their hands and nothing interesting to do. Science can help. Anywhere in the out of doors there is opportunity for real fun with science. In this issue, we describe some of the interesting things you can do and see with rocks and streams and the sides of hills. And we explain some secrets of the clouds. Another good way to make your vacation interesting is to study mud. In the bottoms of sluggish streams and small fresh-water ponds, even water-filled ditches along the roadside, there is a vast and interesting world of tiny creatures. Science calls them animalcules, protozoa, protophyta, and other long names. You cannot see them without a microscope. But for the price of one weekend visit to a moderately fashionable resort you can buy a microscope. You can take it out anywhere and discover this intensely interesting world of the mud dwellers.”

White Ants Destroy Saint Helena
“White ants were introduced into Saint Helena island [in the South Atlantic Ocean] in 1840 in some timber from a slave ship. Mr. M’Lachlan has identified the species termes tenuis, peculiar to South America. The mischief it has done is almost incredible, and it appears to have gradually destroyed the whole of Jamestown. A considerable portion of the books in the public library, especially theological literature, was devoured by them, and the whole of the interior would be destroyed without the exterior of the volumes seeming otherwise than intact.”
The insects are known today as Heterotermes tenuis, a subterranean termite.
Cooking with Gas
“A gas-burning cooking stove has been invented by B. Giles of Blackheath, England. He claims to have succeeded in cooking the most delicate dishes without their imbibing the slightest flavor from the products of combustion.”

The internet has become an integral part of our daily lives, with millions of people around the world relying on it for communication, information, entertainment, and more. However, as the internet has grown in popularity and importance, so too have the risks associated with using it.
One of the biggest concerns when it comes to internet safety is the threat of cyber attacks. Cyber attacks come in many forms, including malware, phishing scams, ransomware, and more. These attacks can have devastating consequences, ranging from identity theft and financial loss to the compromise of sensitive information and even physical harm.
In recent years, there has been a significant increase in the number and severity of cyber attacks, with high-profile incidents making headlines around the world. Organizations of all sizes are being targeted by cyber criminals, who are constantly developing new and more sophisticated ways to breach security systems and steal data.
To protect themselves against cyber attacks, individuals and organizations must take proactive steps to secure their online activities. This includes using strong, unique passwords for all accounts, enabling two-factor authentication whenever possible, keeping software and security systems up to date, and being cautious when clicking on links or downloading attachments.
In addition to these basic precautions, it is also important to invest in robust cybersecurity measures, such as firewalls, antivirus software, and encryption tools. Regularly backing up data and storing it in a secure location can also help mitigate the impact of a cyber attack.
Another important aspect of internet safety is protecting personal information online. With the rise of social media and online shopping, it has become easier than ever for cyber criminals to access sensitive information such as credit card details, addresses, and social security numbers.
To safeguard personal information online, individuals should be wary of sharing too much information on social media, use secure payment methods when making online purchases, and regularly review privacy settings on websites and apps. It is also important to be cautious when sharing personal information with unknown or unverified sources.
Overall, internet safety is a critical issue that affects everyone who uses the internet. By taking proactive steps to secure online activities and protect personal information, individuals and organizations can reduce the risk of falling victim to cyber attacks and ensure a safer and more secure online experience.
