Technologies such as dual x-ray, computer tomography and neutron beam technology will eliminate the need for passengers to remove laptops and other electronic devices.

While the traditional x-ray machines currently used at airports produce a 2-D image, newer technologies such as computer tomography produce a 3-D image with a higher resolution, and have better automated detection of explosives.

The probe into the cyberattack on some servers at AIIMS in the national capital has found that the IP addresses of two emails, which were identified from the headers of files that were encrypted by the hackers, originated from Hong Kong and China’s Henan province. Sources said the senders used the email service Protonmail.

Proton Mail is an end-to-end encrypted email service founded in 2013 in Geneva, Switzerland. It uses client-side encryption to protect email content and user data before they are sent to Proton Mail servers, unlike other common email providers such as Gmail and Outlook.com.

The American football writer Grant Wahl died recently after a catastrophic tear in a major blood vessel leading out of his heart.

An aneurysm is a localised weakening of the wall of a blood vessel, which causes the vessel to bulge in that area — as a result of which the vessel may widen to more than 50 per cent of its usual diameter. Aneurysms are more commonly seen in arteries than in veins.

The aorta is the main artery that carries oxygenated blood from the heart to the rest of the body; it is also the body’s largest blood vessel. An aortic aneurysm is a weakening and bulging in a portion of the aorta; “thoracic” refers to that section of the blood vessel that passes through the chest.

An aneurysm increases in size over time, and the wall of the blood vessel gets progressively weaker in that area. The vessel may ultimately burst or separate, triggering a bleeding rush that can be life-threatening, and potentially lethal.

Possible causes of thoracic aortic aneurysm (i) degenerative disease that causes breakdown of the aortic wall tissue; (ii) genetic disorders; (iii) family history; (iv) vasculitis, or inflammation of the arteries; and (v) atherosclerosis, or the build-up of plaque on the walls of the artery. In rare cases, an infection can also trigger an aneurysm.

• Anthrax is a disease caused by Bacillus anthracis, a spore-forming bacteria.
• Affects animals such as cattle, sheep, and goats more often than people.
• People can get anthrax from contact with infected animals, wool, meat, or hides.
• Spread: It does not spread directly from one infected animal or person to another; it is spread by spores. These spores can be transported by clothing or shoes.
• Gastrointestinal (GI) infection in humans is most often caused by consuming anthrax-infected meat and is characterized by serious GI difficulty, vomiting of blood, severe diarrhea, acute inflammation of the intestinal tract, and loss of appetite.
• Cutaneous anthrax, also known as Hide porter’s disease, is the cutaneous (on the skin) manifestation of anthrax infection in humans.
