After a quantum leap in the digital tech industry over the two past decades, many of us sarcastically said: "The only thing we still miss is the ability to share a meal with the characters in a movie, or to feel what they feel."

However, it seems that the technological progress knows no sarcasm. All the imaginary ideas that people have now, or those they didn't have yet, may soon become a reality that we live.

This is at least what the modern innovations taught us. A team from the Tomsk State University in Russia, announced it has designed a new device that allows humans to feel the "beats," "burns," and even "tinkling" in virtual reality. According to a press release by the university, the new technique can be used in video games.

In addition, the researchers are currently developing their technique so it allows people to feel illusory motions, like when a mosquito settles on their skin or someone draws on their bodies, for instance.

The research team cited several devices that are currently used to transmit the sense of pain in virtual reality; these devices have a wearable skeleton-like structure that transmits the "sense" to the muscles through electric stimulation.

The researchers say the new device is based on the same concept, but it targets the skin without exposing the muscles to an electric pulse.

Researcher Andre Kostornoy, supervisor of the new innovation, said: "The new device affects a precise area of the skin," and stressed "the need for personal settings for each user based on his level of resistance to electrical pulses."

He explained that the principle adopted in the transfer of sensation is based on the same mechanism of brain function. It processes the signal coming from the skin, thereby obtaining a sense of touch, and draws the image of the material or device that comes into contact with the skin at the right moment.

Kostornoy said his team is working on improving the performance of the device so it becomes able to induce a sense of interaction with movements, objects, and characters, like "feeling the touch of another person's palm, for example."

The researcher said "developing this device is a promising achievement that would help control robots through signals communication."



Climate Change Causing More Change in Rainfall, Fiercer Typhoons, Scientists Say

Climate change is driving changes in rainfall patterns across the world, scientists said in a paper published on Friday, which could also be intensifying typhoons and other tropical storms.

Taiwan, the Philippines and then China were lashed by the year's most powerful typhoon this week, with schools, businesses and financial markets shut as wind speeds surged up to 227 kph (141 mph). On China's eastern coast, hundreds of thousands of people were evacuated ahead of landfall on Thursday.

Stronger tropical storms are part of a wider phenomenon of weather extremes driven by higher temperatures, scientists say.

Researchers led by Zhang Wenxia at the China Academy of Sciences studied historical meteorological data and found about 75% of the world's land area had seen a rise in "precipitation variability" or wider swings between wet and dry weather.

Warming temperatures have enhanced the ability of the atmosphere to hold moisture, which is causing wider fluctuations in rainfall, the researchers said in a paper published by the Science journal.

"(Variability) has increased in most places, including Australia, which means rainier rain periods and drier dry periods," said Steven Sherwood, a scientist at the Climate Change Research Center at the University of New South Wales, who was not involved in the study.

"This is going to increase as global warming continues, enhancing the chances of droughts and/or floods."

FEWER, BUT MORE INTENSE, STORMS

Scientists believe that climate change is also reshaping the behavior of tropical storms, including typhoons, making them less frequent but more powerful.

"I believe higher water vapor in the atmosphere is the ultimate cause of all of these tendencies toward more extreme hydrologic phenomena," Sherwood told Reuters.

Typhoon Gaemi, which first made landfall in Taiwan on Wednesday, was the strongest to hit the island in eight years.

While it is difficult to attribute individual weather events to climate change, models predict that global warming makes typhoons stronger, said Sachie Kanada, a researcher at Japan's Nagoya University.

"In general, warmer sea surface temperature is a favorable condition for tropical cyclone development," she said.

In its "blue paper" on climate change published this month, China said the number of typhoons in the Northwest Pacific and South China Sea had declined significantly since the 1990s, but they were getting stronger.

Taiwan also said in its climate change report published in May that climate change was likely to reduce the overall number of typhoons in the region while making each one more intense.

The decrease in the number of typhoons is due to the uneven pattern of ocean warming, with temperatures rising faster in the western Pacific than the east, said Feng Xiangbo, a tropical cyclone research scientist at the University of Reading.

Water vapor capacity in the lower atmosphere is expected to rise by 7% for each 1 degree Celsius increase in temperatures, with tropical cyclone rainfall in the United States surging by as much as 40% for each single degree rise, he said.
