CDC probes cluster of ocular syphilis cases
Syphilis
- It is a Sexually Transmitted Infection (STI).
- It is caused by the bacteria, Treponema pallidum.
- After the infection happens, syphilis bacteria can stay in the body for many years without causing symptoms. But the infection can become active again.
- Transmission:
- Syphilis spreads from person to person through direct contact with these sores.
- It can also be passed to a baby during pregnancy, childbirth and sometimes through breastfeeding.
- Symptoms:
- Syphilis develops in stages. The symptoms vary with each stage and is often painless.
- During the first stage, one or more sores develop on the genitals, rectum, or mouth, and are often painless.
- During the second stage, people may get a rash and experience flu-like symptoms, such as fatigue, fever, a sore throat and muscles aches.
- After the second stage, the symptoms of syphilis are hidden (latent stage).
- Without treatment, syphilis can damage the heart, brain, or other organs. It can become life-threatening.
- Treatment: Syphilis is curable with quick diagnosis and treatment. It is curable with the right antibiotics.

Inflation damper on Goldilocks Effect, RBI projects growth to hit 7 per cent this fiscal
Goldilocks Effect
- The Goldilocks Effect, or the Goldilocks Principle, is the premise that people are inclined to seek ‘just the right’ amount of something.
- People prefer something that is neither too extreme nor too moderate but falls within an optimal or desirable range, fitting their specific needs or preferences.
- The concept is derived from the children''s story of Goldilocks and the Three Bears, where Goldilocks preferred the porridge, chair and bed that were neither too hot nor too cold, too big nor too small, but just right.
- It has a place in several fields and disciplines. It applies to elements of psychology, hard sciences, economics, marketing and engineering, and each one has its own twist on how the principle is applied.
- Goldilocks Pricing:
- It is one of the effect''s more prominent applications. It’s a psychological pricing strategy that rests on the concepts of
- Product differentiation
- Comparative pricing
- Bracketing
- Product differentiation is the practice of distinguishing certain products from others.
- Businesses can only leverage the Goldilocks Effect if they can differentiate their own products from one another.
- This then needs to be combined with something known as comparative pricing where businesses offer multiple versions of a product simultaneously of varying quality, attached to corresponding price points.
- It ultimately informs a comparative pricing strategy involving three options. One that''s too high for most, one that''s too low for most, and one that''s just right.
- When done right, the strategy allows a business to appeal to various parts of the marketregistering with premium buyers, standard consumers and discount seekers.
Green turtles nesting range expands under warming climate
Green Turtle
- The Green turtle (Chelonia mydas)is one of the largest sea turtles and the only herbivore among the different species.
- They are in fact named for the greenish color of their cartilage and fat, not their shells.
- In the Eastern Pacific, a group of green turtles that have darker shells are called black turtles by the local community.
- They graze on seagrasses and algae, which maintains the seagrass beds and makes them more productive.
- These species migrate long distances between feeding grounds and the beaches from where they hatched.
- They are potentially particularly susceptible, as the sex of their offspring is dependent on incubation temperature.
- Distribution: Green turtles are found mainly in tropical and subtropical waters.
- Conservation status
- IUCN: Endangered
- CITES: Appendix 1
- Threats: Habitat loss, fisheries by catch and illegal trade etc.

Can electricity from electric eels transfer genetic material to nearby animals?
- The researchers'' findings add to what we know about electroporation, a gene delivery technique. Electroporation uses an electric field to create temporary pores in the cell membrane. This lets molecules, like DNA or proteins, enter the target cell.
- The researchers thought that if electricity flows in a river, it might affect the cells of nearby organisms. Cells can incorporate DNA fragments in water, known as environmental DNA. To test this, they exposed the young fish in their laboratory to a DNA solution with a marker that glowed in the light to see if the zebrafish had taken the DNA. Then, they introduced an electric eel and prompted it to bite a feeder to discharge electricity.
- The researchers discovered that 5% of the larvae had markers showing gene transfer. This indicates that the discharge from the electric eel promoted gene transfer to the cells, even though eels have different shapes of pulse and unstable voltage compared to machines usually used in electroporation. Electric eels and other organisms that generate electricity could affect genetic modification in nature.
Electric eel
- The scientific name of this species is Electrophorus Electricus which is a fish that only lives in freshwater areas.
- They can release up to 860 volts, which is enough to run a machine.
- They emit a weak electric signal, which they use like radar to navigate, to find a mate, and to find prey.
- Appearance:
- It has a slender, snake-like body and flattened head.
- It has three specialized electric organs—the main electrical organ, the Hunter’s organ and the Sachs’ organ which make up about 80 percent of this fish’s body.
- It can deliver a shock because its nervous system contains a number of disc-shaped electrogenic (electricity-producing) cells called electrocytes.
- Habitat: They dwell mainly on the muddy bottoms of rivers and occasionally swamps, prefering deeply shaded areas.
- Distribution: Its range spans across Brazil, the Guianas, Suriname, Venezuela, Colombia, Ecuador and Peru.
- Conservation status
- IUCN: Least concern
Electroporation
- Electroporation uses an electric field to create temporary pores in the cell membrane. This lets molecules, like DNA or proteins, enter the target cell.
407-million year-old disease-causing fungus unveiled at Natural History Museum
Potteromyces asteroxylicola
- It was found infecting the ancient plant Asteroxylon mackiei, showcasing a predator-prey interaction that occurred while the plant was alive.

- Rhynie Chert site in Scotland is known for its well-preserved Early Devonian communities of plants and animals, including fungi and bacteria.
Devonian Period
- It is spanning between about 2 million and 358.9 million years ago.
- It is sometimes called the “Age of Fishes” because of the diverse, abundant and in some cases, bizarre types of these creatures that swam Devonian seas.
- Forests and the coiled shell-bearing marine organisms known as ammonites first appeared early in the Devonian.
- Late in the period the first four-legged amphibians appeared, indicating the colonization of land by vertebrates.
- During the Devonian, there were three major continental masses: North America and Europe sat together near the equator, with much of their current area covered by shallow seas. To the north lay a portion of modern Siberia. A composite continent of South America, Africa, Antarctica, India, and Australia dominated the southern hemisphere.
