         WE LOVE SCIENCE HERE BECAUSE IT IS A MANY SPLENDOURED THING

     THIS  IS A WAR ZONE WHERE SCIENCE FIGHTS WITH NONSENSE AND WINS                                               

“The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.”             

                    "Being a scientist is a state of mind, not a profession!"

"Knowledge is a Superpower but the irony is you cannot get enough of it with ever increasing data base unless you try to keep up with it constantly and in the right way!" The best education comes from learning from people who know what they are exactly talking about.

Science is this glorious adventure into the unknown, the opportunity to discover things that nobody knew before. And that’s just an experience that’s not to be missed. But it’s also a motivated effort to try to help humankind. And maybe that’s just by increasing human knowledge—because that’s a way to make us a nobler species.

If you are scientifically literate the world looks very different to you.

We do science and science communication not because they are easy but because they are difficult!

How climate change is affecting our health ...

1. Heat waves

Extreme heat days have increased in number and severity worldwide, which brings health challenges like heat stroke and dehydration. While impacts vary by age, gender, location and socioeconomic factors, the elderly and those living in urban areas will experience the highest heat-related death rates in this century.

2. Wildfires

Rising temperatures mean drier forest conditions, resulting in more wildfires.  Wildfire smoke results in emergency room visits to treat respiratory and cardiovascular distress; environmental fallout like poor air,  and supply; and for people fleeing fires or fighting on the front lines, hazards like burns and post-traumatic stress syndrome.

3. Food quality

Extreme temperatures, flooding and rising carbon dioxide levels can affect , safety and distribution and bump up the need for pesticides. Food-borne diseases pose a particular threat, because events like flooding and warming oceans can increase pathogen loads and lead to tainted shellfish.

4. Mental health

Catastrophes caused by climate change create anxiety "vicariously" through news coverage and images of destruction.

"It causes uncertainty—what does it mean for my life and my future? And for the people experiencing it directly, there are serious implications. Having to be evacuated, dealing with property damage and other trauma—all of this impacts mental health." Post-traumatic stress syndrome, depression, aggression, survivor guilt and thoughts of suicide can also result.

Human adaptation to the impacts of climate change is possible but only if greenhouse gas emissions are contained. Scientific data is consistently showing that we only have the ability to prevent these health impacts under a low-emission scenario. But if we continue with the status quo and increase our emissions, the health impacts outstrip our ability to manage them.

Identifying how ecotourism affects wildlife can lower its environmental impact. Human presence is an inherent component of ecotourism, which can impact animal behavior because animals often perceive humans as predators and, consequently, spend more time on human‐directed antipredator behaviors and less on other fitness‐relevant activities. We tested whether human clothing color affects water anole (Anolis aquaticus) behavior at a popular ecotourism destination in Costa Rica, testing the hypothesis that animals are more tolerant of humans wearing their sexually selected signaling color. We examined whether clothing resembling the primary signaling color (orange) of water anoles increases number of anole sightings and ease of capture. Research teams mimicked an ecotourism group by searching for anoles wearing one of three shirt treatments: orange, green, or blue. We conducted surveys at three different sites: a primary forest, secondary forest, and abandoned pasture. Wearing orange clothing resulted in more sightings and greater capture rates compared with blue or green. A higher proportion of males were captured when wearing orange whereas sex ratios of captured anoles were more equally proportional in the surveys when observers wore green or blue. We also found that capture success was greater when more people were present during a capture attempt. We demonstrate that colors “displayed” by perceived predators (i.e., humans) alter antipredator behaviors in water anoles. Clothing choice could have unintended impacts on wildlife, and wearing colors resembling the sexually selected signaling color might enhance tolerance toward humans.

Comment by Dr. Krishna Kumari Challa on Wednesday

Scientists for the first time, manufactured 3-D printed parts that show resistance to common bacteria. This could stop the spread of infections such as MRSA in hospitals and care homes, saving the lives of vulnerable patients.

The research combined 3-D printing with a silver-based antibacterial compound in order to produce the parts.

Results from the research have shown that the anti-bacterial compound can be successfully incorporated into existing 3-D printing materials without any negative influence on processability or part strength, and that under the right conditions, the resultant parts demonstrate anti-bacterial properties without being toxic to human cells. 

The findings offer the potential for applications in a wide range of areas, including , general parts for hospitals which are subject to high levels of human contact, door handles or children's toys, oral health products (dentures) and consumer products, such as mobile phone cases.

Vaginal tobacco- a risky cocktail for women. Women are applying tobacco powder to their genitals to increase sexual pleasure which carries multiple health risks including cancerous lesions experts warn against using it pending research on its effects.

The product is applied either to the skin or the vagina to treat infections or pains, or simply to give pleasure. But it is the aphrodisiac qualities attributed to this “vaginal tobacco” that seem to be the main attraction for consumers in Sédhiou.  the product is made from dried tobacco leaves and the roots of a tree called “tangora” or native plants such as “kankouran mano” or “koundinding”. 
Some manufacturers also add soda and shea butter to the product. But researchers, doctors and other experts in female reproductive systems with experience of treating patients engaged in the practice are clear that the women’s efforts are fruitless. On the therapeutic properties of “vaginal tobacco”, pulmonologist Omar Ba is unequivocal: “There are none.” Ba, who is responsible for Senegal’s tobacco control programme, says this form of tobacco use, well known within his services, has only a “placebo effect” on users.

The product could be giving users the sensation that their genitals are shrinking, due to the reflex retraction of the vaginal muscles when in contact with its chemical components. “However, this feeling is transient and misleading, because the vaginal mucosa that is attacked will eventually develop changes that are the gateway to cancer.

These products often create ulcers which, by scarring, shrink the vagina, make it hard and can go so far as to close it completely. It can even make the normal flow of menstruation impossible.”

Many of the women who have used the product also say they felt burning sensations followed by severe dizziness, vomiting and even loss of consciousness. They also might face complications during deliveries.

Lead aprons role in shielding from X-rays is being questioned. Why out why ...

Lead shields are difficult to position accurately, so they often miss the target area they are supposed to protect. Even when in the right place, they can inadvertently obscure areas of the body a doctor needs to see—the location of a swallowed object, say—resulting in a need to repeat the imaging process, according to the American Association of Physicists in Medicine, which represents physicists who work in hospitals.

Shields can also cause automatic exposure controls on an X-ray machine to increase radiation to all parts of the body being examined in an effort to "see through" the lead.

Moreover, shielding doesn't protect against the greatest radiation effect: "scatter," which occurs when radiation ricochets inside the body, including under the shield, and eventually deposits its energy in tissues.

“Birdbrain” Turns From Insult To Praise  

Some avian species use tools and can recognize themselves in the mirror. How do tiny brains pull off such big feats?

  • Corvids, parrots and other bird groups demonstrate complex cognition, including causal reasoning, mental flexibility, planning, social cognition and imagination.
  • These cognitive abilities were a surprise to many scientists. They were not expected to be found in birds because of their small brains and the absence of a cerebral cortex.
  • Birds compensate for their small brains with a much higher density of neurons. Independently, both birds and mammals have evolved similar neural networks and brain areas that serve cognitive functions.

Sci-com :

A good poster usually follows this format:

  • A good poster must be structured with an entry point, visual balancer, and lots of empty space.
  • A title should have text which is  > 90pt and be placed at the top of the poster
  • The best posters have around three hundred and fifty words, and the maximum should be six hundred words

  • The poster should have fifty five characters per line, for fast reading

  • It should follow the area ratio of twenty percent text, thirty five percent visuals, and forty five percent empty space

  • Dare to be creative.
