Mastercard with LCD screen, keyboard

Mastercard in Singapore has launched a new credit card that has an LCD display and built-in keyboard.

The card has touch-sensitive buttons and the ability to create a 'one-time password', doing away with the need for a separate device sometimes needed to log in to online banking. Many people find using security tokens cumbersome given the need to keep it with them in order to use online banking.

According to the BBC, Mastercard's interactive card aims to solve that issue.
"We brainstormed on ways to make it convenient and yet secure for customers," the report quoted V Subba from Standard Chartered Bank, which is collaborating with Mastercard, as saying. "The question was: instead of sending customers another bulky token, could we replace something which already exists in the customer's wallet? That was when credit, debit and ATM cards immediately came to mind," Subba added.

Spice allergies affecting

foodies and cosmetics users Spices are one of the most widely used products in foods, cosmetics and dental products, but as they are not regulated by US Food and Drug Administration, it becomes difficult for people suffering from allergies to identify or avoid them.

According to rough estimates by allergists at the American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting, spice allergy is responsible for 2 per cent of food allergies. “While spice allergy seems to be rare, with the constantly increasing use of spices in the American diet and a variety of cosmetics, we anticipate more and more Americans will develop this allergy,” allergist Sami Bahna, MD, ACAAI past president, said. “Patients with spice allergy often have to go through extreme measures to avoid the allergen. “This can lead to strict dietary avoidance, low quality of life and sometimes malnutrition,” he said. In his presentation, Bahna noted that due to the wide use of spice in cosmetics, women are more likely to develop spice allergy.
Common spice allergy triggers include cinnamon and garlic, but can range from black pepper to vanilla. Several spice blends contain anywhere from three to 18 spices, and the hotter the spice, the greater the chance for allergy.

Thick-skinned crocs more sensitive than human skin

Crocodiles and alligators, who are known for their thick skin and well-armored bodies, have the most acute sense of touch in the animal kingdom, a new study has revealed.
The crocodilian sense of touch is concentrated in a series of small, pigmented domes that dot their skin all over their body. In alligators, the spots are concentrated around their face and jaws. The study has discovered that these spots contain a concentrated collection of touch sensors that make them even more sensitive to pressure and vibration than human fingertips.

“We didn’t expect these spots to be so sensitive because the animals are so heavily armored,” Duncan Leitch, the graduate student who performed the studies under the supervision of Ken Catania, Stevenson Professor of Biological Sciences at Vanderbilt, said.
Scientists who have studied crocodiles and alligators have taken note of these spots, which they have labeled “integumentary sensor organs” or ISOs. They found a diverse collection of “mechanoreceptors:” nerves that respond to pressure and vibration.
