Study shows that negative signals expressed by adult could have great impact on children

Researchers from the University of Washington well-explored the children’s knowledge and use of gender and race labels. Researchers provides a rare glimpse into how children can learn bias even through nonverbal signals displayed by adults.

A study published in the journal Psychological Science, suggests that negative signals expressed by adults have greater impact on the pre-school children than we ever think of. They catch social bias by seeing these negative signals like condescending tone of voice or disapproving look.

Initially an experiment is done with 67 children ages 4 and 5 on both boys and girls. In this experiment a video is shown to children in which two different female actors displayed positive signals to one woman and negative signals to another. To avoid the possibility of racial bias factoring into results video shows all of the same race.

In the video actors greeted both women in the same way and giving both a toy but the nonverbal expressions were different when interaction with one woman versus another. With one woman they interacted with smile, leaning toward her, using a warm tone of voice and with other by scowling, leaning away and speaking in a cold tone.

After that children were asked who they liked the best. With 67% of children favored the recipient of positive nonverbal signals-suggesting they were influenced by the bias shown in the video by actors.

Sean Parker Teams up to Give Humanity the World’s first Cancer Vaccine.

To defeat cancer, Tech Billionaire Sean Parker is starting $250 million project, which will focus on discovering highly personal tumor tags by using algorithms.

futurology

The Parker institute for Cancer Immunotherapy will work with more than 3 public and private pharmaceutical, biotech, cancer research nonprofits and academic institutions like the Broad Institute of MIT and Harvard, Caltech along with the Cancer Research Institute to bring an end to this disease. The partnership with the Cancer Research Institute will specifically focus on using bioinformatics to uncover these cancer markers.

Neoantigens is a genetic markers found only in tumors and are specific to individuals. It has created the latest buzz in cancer research, particularly in early cancer detection. They are tumor-unique amino acid tags that emerge as cells mutate into cancer. The encode immunologically active proteins that can help the immune system recognize the affected cell as foreign and signal the rest of the body’s infection-fighting army into the fray.

ffffffff

Each participants will study specific gene sequences from both cancerous and non-cancerous tissues, determining which ones are recognizable by t-cells. Once enough data is gathered, it can lead to producing more effective personalized neoantigen vaccines for cancer.

Old Teeth Tell New Stories: One archaeologist created a prehistoric GPS for tracking ancient humans.

oldteethnews

If you want to retrace the life of a person who lived thousands of years ago, than you need to start at the beginning.

You don’t just have teeth in your mouth, but you have around 32 fossils that tell a microscopic history of health. Scientists have found that even the old, discarded, not-so-pearly whites of people that lived thousands of years ago tell a story about them, too.As the hardest substance in the human body, tooth enamel is different. It offers a window into life histories.

When our tooth enamel forms during childhood, it incorporates elements from the local environment, including the dust we breathe from rock layers beneath our feet. On the Other hand, Bones change every few years. Our bones soak up materials around the area we’re buried like a sponge, as we decompose.

Ashley Sharpe, doctoral student of University of Florida, created a map for determining the native place of ancient people and animals in Central America. Archaeologists will use the map to match lead found in bedrock from specific locations to a curious source: millennia-old teeth.

Pinpointing birth and death locations will help Sharpe track and other archaeologists track the movement of prehistoric Maya and potentially solve mysteries surrounding the civilization’s origins and eventual demise.

Giant panda put in the Endangered list after decades of efforts

giant-panda-put-in-the-endangered-list-after-decades-of-efforts

Success is the sum of small efforts, repeated day in and day out. Finally after decades of work by Conservationists they successful in saving the endangered species of Panda.

The official status of the giant panda has been changed from “endangered” to “vulnerable” because of the population rebound in china. The change was announced as part of an update to the International Union for Conservation of Nature (IUCN) Red List.

Giant panda which claims as the china’s national animal have brought its number back to brick. As per latest estimates its number reaches to 1864 adults. There are no exact figures for the numbers of cubs, but estimates bring the total number of giant pandas to 2,060.

IUCN’S updated report said,” “Evidence from a series of range-wide national surveys indicate that the previous population decline has been arrested, and the population has started to increase. The improved status confirms that the Chinese government’s efforts to conserve this species are effective,”

But the rebound could be short-lived, the IUCN warned. Climate change is predicted to wipe out more than one-third of the panda’s bamboo habitat in the next 80 years.

But this update also brought bad news. The eastern gorilla, the world’s largest primate, is now endangered. The number of eastern gorillas has declined more than 70% in the past two decades.
