Ever wonder how much a red blood cell weighs? The world's first mass spectrometer capable of measuring the mass of a single cell or other microparticle -- invented by researchers at the Academia Sinica -- can tell you precisely how much.
The researchers claim that the spectrometer will dramatically reduce the time needed for viral and other medical tests.
The device is the brainchild of Chang Huan-cheng (
The new mass spectrometer that ensnares cells or other nanoparticles in an ion trapping device by producing a laser-induced acoustic wave. The trapped nanoparticles' masses are then measured, according to an Academia Sinica news release.
All that may not mean much to the average lay person, but the device is getting a lot of attention in science and technology circles.
According to Chang, until now, the vital statistics of cells and viruses were measurable only by microscope, which does not generally reveal their mass.
Chang said that being able to measure the weight of cells and other nanoparticles would make testing for diseases -- like cancer -- much easier. The researchers are looking into making a portable version of the spectrometer that can measure smaller viruses like the cold and dengue fever.
LONG FLIGHT: The jets would be flown by US pilots, with Taiwanese copilots in the two-seat F-16D variant to help familiarize them with the aircraft, the source said The US is expected to fly 10 Lockheed Martin F-16C/D Block 70/72 jets to Taiwan over the coming months to fulfill a long-awaited order of 66 aircraft, a defense official said yesterday. Word that the first batch of the jets would be delivered soon was welcome news to Taiwan, which has become concerned about delays in the delivery of US arms amid rising military tensions with China. Speaking on condition of anonymity, the official said the initial tranche of the nation’s F-16s are rolling off assembly lines in the US and would be flown under their own power to Taiwan by way
OBJECTS AT SEA: Satellites with synthetic-aperture radar could aid in the detection of small Chinese boats attempting to illegally enter Taiwan, the space agency head said Taiwan aims to send the nation’s first low Earth orbit (LEO) satellite into space in 2027, while the first Formosat-8 and Formosat-9 spacecraft are to be launched in October and 2028 respectively, the National Science and Technology Council said yesterday. The council laid out its space development plan in a report reviewed by members of the legislature’s Education and Culture Committee. Six LEO satellites would be produced in the initial phase, with the first one, the B5G-1A, scheduled to be launched in 2027, the council said in the report. Regarding the second satellite, the B5G-1B, the government plans to work with private contractors
‘OF COURSE A COUNTRY’: The president outlined that Taiwan has all the necessary features of a nation, including citizens, land, government and sovereignty President William Lai (賴清德) discussed the meaning of “nation” during a speech in New Taipei City last night, emphasizing that Taiwan is a country as he condemned China’s misinterpretation of UN Resolution 2758. The speech was the first in a series of 10 that Lai is scheduled to give across Taiwan. It is the responsibility of Taiwanese citizens to stand united to defend their national sovereignty, democracy, liberty, way of life and the future of the next generation, Lai said. This is the most important legacy the people of this era could pass on to future generations, he said. Lai went on to discuss
MISSION: The Indo-Pacific region is ‘the priority theater,’ where the task of deterrence extends across the entire region, including Taiwan, the US Pacific Fleet commander said The US Navy’s “mission of deterrence” in the Indo-Pacific theater applies to Taiwan, Pacific Fleet Commander Admiral Stephen Koehler told the South China Sea Conference on Tuesday. The conference, organized by the Center for Strategic and International Studies (CSIS), is an international platform for senior officials and experts from countries with security interests in the region. “The Pacific Fleet’s mission is to deter aggression across the Western Pacific, together with our allies and partners, and to prevail in combat if necessary, Koehler said in the event’s keynote speech. “That mission of deterrence applies regionwide — including the South China Sea and Taiwan,” he
