Scientists develop blood test that
predicts whether you'll die in next 10 years
Scientists from
the Max Planck Institute for Biology of Ageing have developed a new blood test
that can predict whether you’ll die within the next 10 years
The test relies on biomarkers in the
blood linked to various factors that appear to affect your risk of death.
To
develop the test, the researchers analysed 44,168 participants aged 18 to 109 -
5,512 of who died during follow-up.
An analysis of the participants’ blood
revealed 14 biomarkers that were associated with an increased risk of death.
These biomarkers were linked to various
factors, including immunity, circulating fat, inflammation and glucose control.
This suggests that in the future, a
sample of your blood could be analysed for the presence of these biomarkers, to
indicate when you’ll die.
In the study, published in Nature Communications , the
researchers, led by Joris Deelen, explained: “We subsequently show that the
prediction accuracy of 5- and 10-year mortality based on a model containing the
identified biomarkers and sex is better than that of a model containing
conventional risk factors for mortality.” PLAY
The
researchers highlight that further research is needed before a clinical test is
available, and this is backed up by experts not involved in the study.
Dr Amanda Heslegrave, a researcher at
the UK Dementia Research Institute, said: “Whilst this study shows that this
type of profiling can be useful, they do point out importantly that it would
need further work to develop a score at the individual level that would be
useful in real life situations.
“We’d need to see: validation to ensure
repeatability in different labs, production of reference samples to test this
on an ongoing basis, work to make the individual score possible, validation in
other cohorts and validation of all components of the panel.
“So, it’s an exciting step, but it’s not
ready yet.”
World’s 1st remote brain surgery via 5G network performed in China Published time: 17 Mar, 2019 13:12 · A Chinese surgeon has performed the world’s first remote brain surgery using 5G technology, with the patient 3,000km away from the operating doctor. Dr. Ling Zhipei remotely implanted a neurostimulator into his patient’s brain on Saturday, Chinese state-run media reports . The surgeon manipulated the instruments in the Beijing-based PLAGH hospital from a clinic subsidiary on the southern Hainan island, located 3,000km away. The surgery is said to have lasted three hours and ended successfully. The patient, suffering from Parkinson’s disease, is said to be feeling well after the pioneering operation. The doctor used a computer connected to the next-generation 5G network developed by Chinese tech giant Huawei. The new device enabled a near real-time connection, according to Dr. Ling. “You barely feel that the patient is 3,000 kilometers away,” he said.
Beijing Orders Alibaba To Dump Media Assets That Rival China's Propaganda Machine BY TYLER DURDEN MONDAY, MAR 15, 2021 - 07:30 PM Beijing is reviving its crackdown on the country's biggest tech firms, reminding the world that the CCP is still focused on neutralizing any and all threats to its control of the Chinese economy and its people. Even after amending China's official ideology to include entrepreneurs among the protected classes represented by the CCP (in addition to workers, farmers and soldiers), Beijing, with President Xi at its center, has apparently decided that Chinese tech firms won't follow the American model after all. Instead, their growth and competitive capabilities will be curtailed for the sake of stability at home. After Tencent was censured and strict new requirements were officailly imposed on Alibaba-owned Ant Group that will prevent the company from growing , the Wall Street Journal reports that next up on Beijing's to-do lis
From Amazon to Wal-Mart, digital retail is producing more jobs and higher pay Written by Mitchell Schnurman, Business columnist May 30, 2017 Retail trade is one of the biggest job sectors in America, and the vast majority of those workers still clock in at brick-and-mortar stores. But the big growth is coming from e-commerce, which happens to pay a lot better, too. This is a promising development for retail workers who worry about thousands of store closings and the march of automation. E-commerce also offers a potential antidote to years of low productivity growth and income stagnation. “If this new pattern continues, it will raise real wages across the economy and rejuvenate the middle class,” said a report by economist Michael Mandel of the Progressive Policy Institute in Washington. By his definition, e-commerce includes online shopping, mail order and warehousing. That’s a more expansive category than usual and was created to capture the growth in what M
