During the recent Display Week trade show held in Los Angeles, Samsung unveiled an impressive 12.4-inch rollable OLED panel, which has the potential to revolutionize the display industry. While rollable display concepts have been introduced before, Samsung’s innovation stands out from the competition due to its significant advancements. This groundbreaking display is not only the largest rollable panel seen to date but also rolls up into a compact scroll, adding to its appeal and practicality.
At the recent Display Week trade show in Los Angeles, Samsung showcased a remarkable 12.4-inch rollable OLED panel that introduces significant advancements to the display industry. One standout feature of this innovation is its impressive scalability, ranging from 49mm to 254.4mm. This represents a remarkable 5x scalability, surpassing the current sliding screens that can only expand up to 3x their original size. Samsung Display accomplished this feat by implementing an O-shaped axis design, reminiscent of a scroll, which they aptly named Rollable Flex. Notably, the panel has the capability to be completely rolled up, adding to its versatility and user-friendly design.
Samsung showcased the Rollable Flex, a fully rollable OLED panel, and the Flex In & Out OLED panel at the Display Week trade show. The Flex In & Out panel allows bending in both directions, unlike current technology used in devices like the Galaxy Flip4 and Fold4.
Last, but not least, the Korean tech giant also introduced the world’s first OLED panel with an integrated fingerprint reader and heart rate sensor. Current implementations rely on a small sensor area while Samsung’s solution allows you to unlock the handset with a touch of a finger anywhere on the screen surface. It has embedded the light-sensing organic photodiode (OPD) into the panel itself. The tech can also read blood pressure, heart rate and stress by monitoring the blood vessels’ contraction and relaxation.
New research suggests that New York City is sinking due to its massive concrete buildings. Some areas are even sinking twice as fast as the rising sea levels.
What’s happening to New York?
New York City, famously called the Big Apple, is facing a sinking problem.
Research by the University of Rhode Island and the US Geological Survey indicates that the city is sinking at a rate of 1-2 mm per year.
Some areas of the city are sinking at a faster pace than others.
The weight of the city’s buildings, totaling approximately 1.68 trillion pounds, contributes to the sinking.
Lower Manhattan, situated only a few meters above sea level, is particularly at risk.
Rising sea levels, up by 9 inches since 1950, worsen the situation for the city.
What does this mean for the future of New York?
Researchers emphasize that immediate panic is unwarranted regarding the sinking of New York City, but the city administration should prepare for the increased risk of flooding.
Flooding poses risks beyond loss of life, including infrastructure damage due to saltwater corrosion and weakened concrete.
While building in the city wasn’t a mistake, each new construction contributes to the city sinking further.
In 2021, Hurricane Ida caused significant flooding in various areas of the city, resulting in multiple drownings. Major flooding is projected to occur four times more frequently by the end of the century.
New York City is not alone in facing such challenges; numerous cities worldwide are also confronting a looming doomsday scenario, albeit seemingly distant.
These are the world’s fasted sinking cities:
Jakarta, Indonesia
Jakarta, Indonesia’s capital, holds the title of the world’s fastest sinking city.Over the past decade, the northern part of the city has sunk by 2.5 meters, with nearly 50% of the city now below sea level.To address this alarming situation, the Indonesian government has begun constructing a new capital called Nusantara in a different location.
Lagos, Nigeria
Africa’s largest coastal city is experiencing rapid erosion, and a 2012 study from the University of Plymouth warns that a sea level rise of 3-9 feet would have catastrophic consequences.
Houston, Texas, USA
Houston, a city in the US, is sinking due to excessive groundwater pumping, with some areas experiencing a subsidence rate of 2 inches per year.
Bangkok, Thailand
Bangkok is sinking at a rate of 2 cm per year, and certain areas are sinking even faster due to aquifer systems and the weight of buildings.
Ho Chi Minh City, Vietnam
Ho Chi Minh City is sinking at a rate of 5 cm per year, with the sinking process beginning as early as 1990.
Mumbai, India
South Mumbai is at risk of being submerged in the Arabian Sea by 2050 due to global warming and other factors.
In conclusion, numerous coastal cities worldwide are facing the threat of rising sea levels and dense infrastructure. While witnessing cities disappearing underwater may not happen within our lifetime, the lives of residents are certain to become increasingly challenging and unfavorable as a consequence.
Scientists have discovered that mosquitoes are most attracted to certain scents found in human body odor.
Odor refers to a smell or scent that can be detected by the nose. It is the characteristic aroma that is produced by substances or living organisms.
Scientists have found out that mosquitoes are attracted to the smells produced by humans. They conducted experiments by creating a large testing area and introducing different scents of people to determine which chemicals in body odor attract mosquitoes. While mosquitoes typically feed on nectar, female mosquitoes require a blood meal to produce eggs. Mosquito bites can be itchy and red, but they can also transmit dangerous diseases like malaria, making them potentially deadly.
Malaria is a disease caused by parasites that reside in red blood cells. When a mosquito bites an infected person, it ingests the parasite along with the blood. The parasite develops inside the mosquito and eventually moves to its salivary glands. When the mosquito bites another person, it injects the parasite into their skin, causing infection. While malaria has been eliminated in the United States through measures like window screens and improved drainage systems, it remains a significant threat in many parts of the world.
“Malaria causes over 600,000 deaths yearly, particularly among children under 5 and pregnant women,” said Dr. McMeniman, lead researcher. The study aimed to understand how malaria-transmitting mosquitoes locate humans. Researchers focused on Anopheles gambiae, a mosquito species found in sub-Saharan Africa, partnering with Zambia’s Macha Research Trust. They observed the mosquitoes’ scent preferences, tracking abilities up to 66 feet (20 meters), and studied their behavior during peak activity from 10 p.m. to 2 a.m.
Researchers built a large screened facility resembling a skating rink to study mosquito attraction. Participants slept in screened tents, and their breath and body odor scents were pumped into the facility to mimic sleeping humans. Mosquitoes were exposed to these scents, and their movements were tracked using infrared cameras. The study found that some people attracted more mosquitoes than others, with carboxylic acids, like butyric acid found in stinky cheeses, being most attractive. Another chemical, eucalyptol, seemed to deter mosquitoes. These findings could help develop lures or repellents to control malaria-carrying mosquitoes. While the research doesn’t have immediate applications, it provides valuable insights into mosquito hunting behavior.
