When a genetic testing kit promising to predict a baby's gender with 99.9 percent accuracy five weeks after conception was launched last year, many pregnant women in the US were delighted.
About 4,500 bought the kit and began making plans for the new arrival. Names were chosen; nurseries painted; siblings coached to say brother, or sister; and then, several weeks later, about 100 discovered that the tests had got it wrong.
In a class action lawsuit filed in the US district court in Boston on behalf of 16 women the makers of the Baby Gender Mentor are accused of breaking their promise. Barry Gainey, the women's lawyer, said he knew of about 100 women whom the kit had failed.
The suit seeks to bar Acu-Gen Biolab from falsely marketing its test and to compel the firm to honor its money-back guarantee. The Baby Gender Mentor's Web site promises "unsurpassed accuracy" in predicting the sex of a fetus from three drops of a pregnant woman's blood, allowing parents to form a "natural nexus with your baby early on."
The test, which costs US$275, claims to detect fetal chromosomes in the maternal blood stream. Women do it at home and send it to Massachusetts for processing. They are promised double their money back on production of a birth certificate if the result is wrong.
But within weeks of taking the test dozens of pregnant women reported having ultrasound scans showing they were having babies of the opposite gender. When they complained to Acu-Gen they were told ultrasounds were unreliable predictors of gender. But after their babies were born the company proved just as reluctant to honor its promise. One of Gainey's clients was told that her child had gender irregularities.
"If he sold 4,000 tests he has got a right to have four women get it wrong, but he is way over that number," Gainey said.
The Acu-Gen president, CN Wang, has issued the following statement: "Dr Wang has decided to defer all his interviews regarding Baby Gender Mentor product and service for one more year, when the results of actual births ... should answer any concern of the accuracy of the test."
RUN IT BACK: A succesful first project working with hyperscalers to design chips encouraged MediaTek to start a second project, aiming to hit stride in 2028 MediaTek Inc (聯發科), the world’s biggest smartphone chip supplier, yesterday said it is engaging a second hyperscaler to help design artificial intelligence (AI) accelerators used in data centers following a similar project expected to generate revenue streams soon. The first AI accelerator project is to bring in US$1 billion revenue next year and several billion US dollars more in 2027, MediaTek chief executive officer Rick Tsai (蔡力行) told a virtual investor conference yesterday. The second AI accelerator project is expected to contribute to revenue beginning in 2028, Tsai said. MediaTek yesterday raised its revenue forecast for the global AI accelerator used
TEMPORARY TRUCE: China has made concessions to ease rare earth trade controls, among others, while Washington holds fire on a 100% tariff on all Chinese goods China is effectively suspending implementation of additional export controls on rare earth metals and terminating investigations targeting US companies in the semiconductor supply chain, the White House announced. The White House on Saturday issued a fact sheet outlining some details of the trade pact agreed to earlier in the week by US President Donald Trump and Chinese President Xi Jinping (習近平) that aimed to ease tensions between the world’s two largest economies. Under the deal, China is to issue general licenses valid for exports of rare earths, gallium, germanium, antimony and graphite “for the benefit of US end users and their suppliers
Dutch chipmaker Nexperia BV’s China unit yesterday said that it had established sufficient inventories of finished goods and works-in-progress, and that its supply chain remained secure and stable after its parent halted wafer supplies. The Dutch company suspended supplies of wafers to its Chinese assembly plant a week ago, calling it “a direct consequence of the local management’s recent failure to comply with the agreed contractual payment terms,” Reuters reported on Friday last week. Its China unit called Nexperia’s suspension “unilateral” and “extremely irresponsible,” adding that the Dutch parent’s claim about contractual payment was “misleading and highly deceptive,” according to a statement
The Chinese government has issued guidance requiring new data center projects that have received any state funds to only use domestically made artificial intelligence (AI) chips, two sources familiar with the matter told Reuters. In recent weeks, Chinese regulatory authorities have ordered such data centers that are less than 30 percent complete to remove all installed foreign chips, or cancel plans to purchase them, while projects in a more advanced stage would be decided on a case-by-case basis, the sources said. The move could represent one of China’s most aggressive steps yet to eliminate foreign technology from its critical infrastructure amid a
