Two Chinese researchers have created a prototype device that can be taped to the skin to measure the motions and vibrations of the vocal cords and transform them into sounds.

The researchers also improved the device so it becomes thinner and lighter, so when attached to the neck like a temporary tattoo, it doesn't cause the wearer any discomfort, the German News Agency reported.

According to the ACS Nano journal, speech is actually a complex process that involves both motions of the mouth and vibrations of folded tissues, called vocal cords, within the throat. If the vocal cords sustain injuries or other lesions, a person can lose the ability to speak.

Researchers He Tian, Yi Yang, Tian-Ling Ren and colleagues used graphene on a thin sheet of polyvinyl alcohol film. The flexible device measured 0.6 by 1.2 inches, or about double the size of a person's thumbnail.

The researchers used water to attach the film to the skin over a volunteer's throat and connected it with electrodes to a small armband that contained a circuit board, microcomputer, power amplifier and decoder.

The Science Daily website reported that the instrument converts the throat's movements into emitted sounds, such as the words "OK" and "No."

The researchers say that, in the future, mute people could be trained to generate signals with their throats that the device would translate into speech.

Beverage giant Coca-Cola has agreed to use real cane sugar in its US production, President Donald Trump announced Wednesday on social media.

The company currently uses high-fructose corn syrup (HFCS) in its domestic beverages -- a sweetener that has long drawn criticism from Health Secretary Robert F. Kennedy Jr. and his Make America Healthy Again movement, AFP said.

"I have been speaking to Coca-Cola about using REAL Cane Sugar in Coke in the United States, and they have agreed to do so," Trump wrote on his Truth Social platform.

"I'd like to thank all of those in authority at Coca-Cola. This will be a very good move by them -- You'll see. It's just better!"

The US president did not explain what motivated his push for the change, which would not impact his well-known favorite beverage, Diet Coke.

Since his return to the White House, Trump has re-installed a special button in the Oval Office which summons a helping of the sugar-free carbonated drink.

Coca-Cola did not immediately confirm the ingredient shift.

"We appreciate President Trump's enthusiasm for our iconic Coca‑Cola brand. More details on new innovative offerings within our Coca‑Cola product range will be shared soon," the company said in a short statement.

HFCS became popular in the 1970s, with its use skyrocketing thanks to government subsidies for corn growers and high import tariffs on cane sugar.

Any shift away from corn is likely to draw backlash in the Corn Belt, a Midwestern region that has been a stronghold of support for Trump.

Both HFCS and sucrose (cane sugar) are composed of fructose and glucose. However, they differ structurally: HFCS contains free (unbonded) fructose and glucose in varying ratios -- 55/45 in soft drinks -- while sucrose consists of the two sugars chemically bonded together.

These structural differences, however, don't appear to significantly affect health outcomes.

A 2022 review of clinical studies found no meaningful differences between HFCS and sucrose in terms of weight gain or heart health.

The only notable distinction was an increase in a marker of inflammation in people consuming HFCS. Overall, both sweeteners appear similarly impactful when consumed at equal calorie levels.

Despite this, Mexican Coke -- which is made with cane sugar -- is often sold at a premium in US stores and prized for its more "natural" flavor.

Trump's prized Diet Coke is sweetened with aspartame -- a compound classified as a "possible carcinogen" by the International Agency for Research on Cancer (IARC).
