Facebook changes Trending Topics policies after criticism

Gorkha Post

SAN FRANCISCO — Facebook says it has changed some of the procedures behind its Trending Topics section on Monday, after a news report alleging it suppressed conservative news prompted a US Congressional demand for more transparency.

The social media giant said an internal probe showed no evidence of political bias in the selection of news stories for Trending Topics, a feature that is separate from the main ‘news feed’ where most Facebook users get their news.

But the company said in a blogpost that it was introducing several changes, including elimination of a top-10 list of approved websites, more training and clearer guidelines to help human editors avoid ideological or political bias, and more robust review procedures.

Earlier this month, a former Facebook contractor had accused the company’s editors of deliberately suppressing conservative news. The allegations were reported by technology news website Gizmodo, which did not identify the ex-contractor.

The report led Republican senator John Thune to write a letter demanding that the company explain how it selects news articles for its Trending Topics list. He gave a deadline of May 24.

“Any attempt by a neutral and inclusive social media platform to censor or manipulate political discussion is an abuse of trust and inconsistent with the values of an open internet,” he said.

Two days after Thune’s letter, Facebook published a lengthy blogpost detailing how Trending Topics works even though it rarely discloses such practices.

Previously, it had never discussed the inner workings of the feature, which displays topics and news articles in the top right-hand corner of the desktop homepage for its more than 1.6 billion users.

Facebook said its investigation showed that conservative and liberal topics were approved as trending topics at nearly identical rates.

It said it was unable to substantiate any allegations of politically motivated suppression of particular subjects or sources.

However, it did not rule out human error in selecting topics.

“Our investigation could not fully exclude the possibility of isolated improper actions or unintentional bias in the implementation of our guidelines or policies,” Facebook’s general counsel Colin Stretch said.

Researchers successfully grow human cells in sheep embryos

KATHMANDU — In an incredible development that could possibly go a long way in medical practices, scientists in California are working on a way to reduce organ transplants and rejections: Growing embryos in sheep and pigs containing human patients’ cells.

In a transplant breakthrough, scientists at the University of California said they have achieved sheep embryos in which around one in every 10,000 cells was human, according to UPI report.

The researchers presented preliminary findings Saturday at the American Association for the Advancement of Science’s annual meeting in Austin, Texas.

The new finding paves way for genetically tailoring the organs to be compatible with the immune system of the patient receiving them, thus removing the possibility of rejection, the report said.

The hybrid embryos contain both human and sheep cells and were created in an early step toward growing human organs in farm animals before transplanting them into patients.

Last year, the same researchers introduced human stem cells into early pig embryos, producing embryos with about one in every 100,000 cells being human.

The experiment began with Hiro Nakauchi, from the University of Tokyo, who grew a mouse with a rat pancreas and a rat with a mouse pancreas.

When cells from the rat-grown mouse pancreas were transplanted into a diabetic mouse, they made enough insulin to cure the condition without being rejected.

Mice and rats are different types of rodents with the former having thin slightly hairy tails, while rats have thicker hairless scaly tails.

“The next step was to move into large animals,” Nakauchi said. Since this was prohibited in Japan, he moved to the Stanford University in the US.

Nakauchi’s rodent work has demonstrated that you can “grow organs in a different species and cure a disease without [suppressing the immune system],” added co-researcher Pablo Ross, Professor at from the University of California, Davis.

“We are working together to translate the technology into humans, to solve the terrible shortage of organs for transplantation. In the US, 20 people die every day because they cannot get the organs they need,” Ross explained.
