saco-indonesia.com, Apabila sekarang ini mayoritas perangkat mobile telah menggunakan produk dari Corning yaitu Gorilla Glass, ada pula rumor bahwa akan dibuatnya layar berbahan safir. Kali ini muncul berita serupa yaitu layar berbahan kulit kerang.

Para peneliti dari McGill University, Kanada, ingin mencoba mengembangkan sebuah layar yang tahan banting dan benturan. Para peneliti tersebut telah terinspirasi dari kekuatan kerang.

Dikutip dari Cnet (30/01), para peneliti tersebut juga menjelaskan, "Kerang moluska telah memiliki lapisan luar yang boleh terbilang rapuh, namun apabila jika dibandingkan dengan bagian dalamnya, maka sangat berbeda, karena sangat kuat."

Oleh karena itu, para peneliti yang telah dipimpin oleh Profesor Francois Barthelat itu ingin mencoba meneliti dan meniru lapisan demi lapisan termasuk juga jaringan yang terdapat pada kerang untuk dapat diaplikasikan ke sebuah layar anti-bentur.

Barthelat juga berharap nantinya apabila penelitian yang dia lakukan bersama tim-nya itu akan berhasil, maka tidak hanya di perangkat mobile saja , penemuannya itu dapat juga digunakan di banyak hal.

LAYAR SMARTPHONE TERKUAT SEDANG DALAM PROSES PENGEMBANGAN

Public perceptions of race relations in America have grown substantially more negative in the aftermath of the death of a young black man who was injured while in police custody in Baltimore and the subsequent unrest, far eclipsing the sentiment recorded in the wake of turmoil in Ferguson, Mo., last summer.

Americans are also increasingly likely to say that the police are more apt to use deadly force against a black person, the latest New York Times/CBS News poll finds.

The poll findings highlight the challenges for local leaders and police officials in trying to maintain order while sustaining faith in the criminal justice system in a racially polarized nation.

Sixty-one percent of Americans now say race relations in this country are generally bad. That figure is up sharply from 44 percent after the fatal police shooting of Michael Brown and the unrest that followed in Ferguson in August, and 43 percent in December. In a CBS News poll just two months ago, 38 percent said race relations were generally bad. Current views are by far the worst of Barack Obama’s presidency.

The negative sentiment is echoed by broad majorities of blacks and whites alike, a stark change from earlier this year, when 58 percent of blacks thought race relations were bad, but just 35 percent of whites agreed. In August, 48 percent of blacks and 41 percent of whites said they felt that way.

Looking ahead, 44 percent of Americans think race relations are worsening, up from 36 percent in December. Forty-one percent of blacks and 46 percent of whites think so. Pessimism among whites has increased 10 points since December.

The poll finds that profound racial divisions in views of how the police use deadly force remain. Blacks are more than twice as likely to say police in most communities are more apt to use deadly force against a black person — 79 percent of blacks say so compared with 37 percent of whites. A slim majority of whites say race is not a factor in a police officer’s decision to use deadly force.

Overall, 44 percent of Americans say deadly force is more likely to be used against a black person, up from 37 percent in August and 40 percent in December.

Blacks also remain far more likely than whites to say they feel mostly anxious about the police in their community. Forty-two percent say so, while 51 percent feel mostly safe. Among whites, 8 in 10 feel mostly safe.

One proposal to address the matter — having on-duty police officers wear body cameras — receives overwhelming support. More than 9 in 10 whites and blacks alike favor it.

Asked specifically about the situation in Baltimore, most Americans expressed at least some confidence that the investigation by local authorities would be conducted fairly. But while nearly two-thirds of whites think so, fewer than half of blacks agree. Still, more blacks are confident now than were in August regarding the investigation in Ferguson. On Friday, six members of the police force involved in the arrest of Mr. Gray were charged with serious offenses, including manslaughter. The poll was conducted Thursday through Sunday; results from before charges were announced are similar to those from after.

Reaction to the recent turmoil in Baltimore, however, is similar among blacks and whites. Most Americans, 61 percent, say the unrest after Mr. Gray’s death was not justified. That includes 64 percent of whites and 57 percent of blacks.
