A long-awaited report from a U.S. House antitrust subcommittee landed this week, and it slammed Amazon, Facebook, Google and Apple for their alleged monopolistic practices in the online marketplaces they operate. Amazon responded with a scathing blog post that said the report featured “flawed thinking.”

Limited safety, sustainability and recyclability are key drawbacks of today’s lithium-ion battery technology, along with restricted availability of starting materials (e.g. cobalt). In the search for alternative electrochemical energy storage systems for use in e-mobility and for storing energy from renewable sources, a combination of battery and capacitor is very promising: the “hybrid supercapacitor.” It can be charged and discharged as quickly as a capacitor and can store almost as much energy as conventional batteries. In comparison to the latter, it can be charged and discharged much faster and much more frequently: while a lithium-ion battery achieves a service life of a few thousand cycles, a supercapacitor manages around one million charging cycles.
System made of carbon and salt water
A particularly sustainable, but so far quite unexplored variant of such a hybrid supercapacitor consists of carbon and aqueous sodium iodide (NaI) electrolyte, with a positive battery electrode and a
A long-awaited report from a U.S. House antitrust subcommittee finds that Amazon “has monopoly power over most third-party sellers and many of its suppliers,” and proposes sweeping reforms for U.S. tech giants including “structural separations to prohibit platforms from operating in lines of business that depend on or interoperate with the platform.”
Amazon called the report fundamentally flawed, saying its “fringe notions on antitrust” presented an inaccurate view of the market and competitive landscape.
The 450-page report from the subcommittee’s Democratic leaders concludes a 16-month investigation into Facebook, Google, Amazon and Apple as the operators of major online markets. It finds that the market power of the four tech giants “has diminished consumer choice, eroded innovation and entrepreneurship in the U.S. economy, weakened the vibrancy of the free and diverse press, and undermined Americans’ privacy.”
Children appear to be at greater risk of having high blood pressure when their mothers had the high blood pressure condition called preeclampsia during pregnancy — but this adverse association may be reduced or even eliminated for children who were exposed to higher levels of vitamin D in the womb, according to a study from researchers at Johns Hopkins Bloomberg School of Public Health.
The findings, based on an analysis of data on 754 mother-child pairs in Massachusetts, suggest that higher vitamin D levels in pregnancy may help protect children born to preeclamptic women from developing high blood pressure. High blood pressure in childhood is associated in turn with hypertension and heart disease in adulthood.
The study was published online October 5 in JAMA Network Open.
“There is increasing evidence that cardiovascular disease risk is, to a great extent, programmed in the womb, and we now see that it
We hear sounds in part because tiny filaments inside our inner ears help convert voices, music and noises into electrical signals that are sent to our brains for processing. Now, scientists have mapped and simulated those filaments at the atomic level, a discovery that shed lights on how the inner ear works and that could help researchers learn more about how and why people lose the ability to hear.
The findings, published last week in the Proceedings of the National Academy of Sciences, involve very fine filaments in the inner ear called tip links. When sound vibrations reach the inner ear, the vibrations cause those tip links to stretch and open ion channels of sensory cells within the inner-ear cochlea, a tiny snail-shaped organ that allows our brains to sense sound. When tip links open those channels, that act triggers the cochlear electrical signals that we interpret as sound.
Scientists have challenged a popular theory behind the evolution of similar traits in island lizards, in a study published recently in eLife.
The findings in Greater Antillean Anolis lizards provide insights on why creatures often evolve similar physical features independently when living in similar habitats. They suggest that the role of developmental plasticity in shaping adaptive evolution may be less important than commonly thought.
Developmental plasticity refers to how development responds to the environment, in particular the way that an organism’s genetic constitution (or genotype) interacts with its environment during development to produce a particular set of characteristics (or phenotype).
“Anolis lizards that live on all four of the Greater Antillean islands have independently and repeatedly evolved six different body types for maneuvering through their given habitat,” says lead author Nathalie Feiner, Researcher at the Department of Biology, Lund University, Sweden. “As a result, they make a great model

New research has identified a mechanism by which low levels of insecticides such as, the neonicotinoid Imidacloprid, could harm the nervous, metabolic and immune system of insects, including those that are not pests, such as our leading pollinators, bees.
A study published today in the Proceedings of the National Academy of Sciences led by researchers at the University of Melbourne and Baylor College of Medicine, shows that low doses of Imidacloprid trigger neurodegeneration and disrupt vital body-wide functions, including energy production, vision, movement and the immune system, in the vinegar fly, Drosophila melanogaster.
With insect populations declining around the world and intense use of insecticides suspected to play a role, the findings provide important evidence that even small doses of insecticides reduce the capacity of insects to survive, even those that are not pests.
“Our research was conducted on one insecticide, but there is evidence that other insecticides cause
Researchers have identified two antibodies that protect mice against lethal infections of influenza B virus, report scientists at Washington University School of Medicine in St. Louis and Icahn School of Medicine at Mount Sinai. Together with an antibody that targets the other major kind of influenza viruses that infect people — influenza A — these antibodies potentially could form the basis of a broad-spectrum flu drug that could treat almost all flu cases.
The findings are published Sep. 24 in the journal Immunity.
“People forget that before COVID-19 hit last winter, we were already in the midst of a really bad influenza season, especially for children,” said co-senior author Ali Ellebedy, PhD, an assistant professor of pathology and immunology at Washington University. “Last year, influenza B viruses attacked much earlier in the season than usual and resulted in significant illness and death among children. We really need better treatments
LANHAM, Md. and CAPE TOWN, South Africa, Sept. 28, 2020 /PRNewswire/ — GetSmarter, a 2U, Inc. (Nasdaq: TWOU) brand, today announced the results of a survey exploring the future of work, as accelerated by the COVID-19 pandemic. The “Future of Work is Here” data highlights the value of continued learning as technology and automation change the workforce, details the importance of upskilling and reskilling, and emphasizes the value of soft skills.
The survey of over 8,000 global respondents across industries was first conducted by GetSmarter in November 2019, with a second survey in May 2020 to capture the new realities brought on by COVID-19. While workforces are now largely remote, the findings from the second deployment were directionally consistent with the results of the first wave of fieldwork, underscoring the value of this data and its learnings for both remote and in-person employers and employees.
