The total amount of data generated worldwide is expected to reach 175 ZB (Zettabytes; 1 ZB equals 1 billion Terabytes) by 2025. If 175 ZB were stored on Blu-ray disks, the disk stack would be 23 times the distance to the Moon. We face the urgent need to develop storage technologies that can accommodate this enormous amount of data.
ROCKVILLE, MD - Scientists are still a long way from being able to treat Alzheimer's Disease, in part because the protein aggregates that can become brain plaques, a hallmark of the disease, are hard to study. The plaques are caused by the amyloid beta protein, which gets misshapen and tangled in the brain. To study these protein aggregates in tissue samples, researchers often have to use techniques that can further disrupt them, making it difficult to figure out what's going on.
Our use of social media, specifically our efforts to maximize "likes," follows a pattern of "reward learning," concludes a new study by an international team of scientists. Its findings, which appear in the journal Nature Communications, reveal parallels with the behavior of animals, such as rats, in seeking food rewards.
The koala retrovirus (KoRV) is a virus which, like other retroviruses such as HIV, inserts itself into the DNA of an infected cell. At some point in the past 50,000 years, KoRV has infected the egg or sperm cells of koalas, leading to offspring that carry the retrovirus in every cell in their body. The entire koala population of Queensland and New South Wales in Australia now carry copies of KoRV in their genome.
PHILADELPHIA-- Even though the use of rhythm control strategies for treating Paroxysmal Atrial Fibrillation (AF), a common abnormal heart rhythm, have increased overall in the United States, patients from racial and ethnic minority groups and those with lower income were less likely to receive rhythm control treatment - often the preferred treatment - according to new
When a muscle grows, because its owner is still growing too or has started exercising regularly, some of the stem cells in this muscle develop into new muscle cells. The same thing happens when an injured muscle starts to heal. At the same time, however, the muscle stem cells must produce further stem cells - i.e., renew themselves - as their supply would otherwise be depleted very quickly. This requires that the cells involved in muscle growth communicate with each other.
Muscle growth is regulated by the Notch signaling pathway
New York, NY (February 26, 2020) - Molecules called microRNAs (miRNAs) that are measurable in urine have been identified by researchers at Mount Sinai as predictors of both heart and kidney health in children without disease. The epidemiological study of Mexican children was published in February in the journal Epigenomics.
Who would have thought that a small basic compound like vitamin B6 in the banana or fish you had this morning may be key to your body's robust response against COVID-19?
Living in a group has clear benefits. As a member of a societal group, one can share resources with the others, seek protection from predators, and forage in an efficient manner.
The centre is part of the German Federal Institute for Risk Assessment (BfR). With the help of microscopy and artificial intelligence, the "E-Morph" test reliably identifies substances that can have oestrogen-like or even opposing effects, according to the research team's report in the specialist journal "Environment International". "E-Morph is a milestone on the way to, one day, replacing animal experiments currently required to detect hormone-like effects," says BfR President Prof. Dr. Dr. Andreas Hensel.
A number of brain areas change their activity before we execute a planned voluntary movement. A new study by Umeå University identifies a novel function of this preparatory neural activity, highlighting another mechanism the nervous system can use to achieve its goals.
Cells rely on membranes to protect themselves from the outside world. But these membranes can't be fully closed because nutrients and other molecules have to be able to pass through. To achieve this, cell membranes have many types of channels and pores. Also, there are receptors, antennas if you like, imbedded in the membrane that continuously monitor the outside world and signal to the cell interior. Extensive collaboration between five VIB groups resulted in a better understanding of the machinery that plants use to regulate the protein composition of their outer membrane.
The Korea Institute of Machinery and Materials (KIMM) successfully developed all-round gripper* technology, enabling robots to hold objects of various shapes and stiffnesses. With the new technology, a single gripper can be used to handle different objects such as screwdrivers, bulbs, and coffee pots, and even food with delicate surfaces such as tofu, strawberries, and raw chicken.
IRS refers to the application of insecticide onto the interior walls of houses.
The study, by the Wits Research Institute for Malaria (WRIM) and the London School of Hygiene and Tropical Medicine (LSHTM), was published in The Lancet on 25 February 2021.

Malaria still represents one of the world's largest health crises, particularly on the African continent where 94% of cases and deaths occur (World Health Organization, 2020).
Prior to the emergence of new mutants of the coronavirus, such as the British variant B.1.1.7, the SARS-CoV-2 variant named D614G had already mutated from the original SARS-CoV-2 pathogen that triggered the pandemic. D614G has rapidly spread to become the most abundant variant worldwide and this D614G mutation remains in all the new emerging variants. An international team including researchers from Bern has now been able to demonstrate in both the laboratory and in animal models why the D614G variant was able to gain the upper hand over the original SARS-CoV-2 virus.
