External hard drives for social media users

19.06.2012

The new hard drives allow one-button backup of photos and videos stored on Facebook and Flickr. Seagate Technology has introduced a new line of external hard drives - Backup Plus. The new drives are the first on the market designed to automatically back up user photos and videos stored on Facebook and Flickr, according to the manufacturer's press service.

"It's an interesting idea to back up photos and videos stored on social networks to a local device. I think this will help people understand the benefits of storing multiple copies of content, regardless of where it is originally located," commented Brett Sappington ( Brett Sappington, director of research at Parks Associates, "Social media has been playing the role of a huge repository of personal digital content for some time now, and most users don't think they can lose that data."

More than half of Americans (54%) have experienced a file loss or have a friend who has lost information, according to a survey commissioned by Harris Interactive for Seagate in late May. More than a quarter (27%) of those surveyed lost personal files. Moreover, of all respondents, only 11% regularly use reservations.

When using Backup Plus hard drives, backing up photos and videos from Facebook and Flickr is done at the touch of a button using the included Seagate Dashboard software. The same software allows you to upload content from your hard drive to the Internet, as well as make backup copies of files stored on a personal computer to which the drive is connected.

The Seagate Backup Plus lineup includes 2,5GB, 500GB, and 750TB 1-inch pocket models with MSRPs of $120, $130, and $140, respectively, and 3,5TB, 1TB, 2TB, and 3TB desktop models (4 inches) priced at $130, $150, $180, and $250 respectively for Windows computers. Macs are available in 500GB and 1TB mobile models for $120 and $140, and 2TB and 3TB desktop models for $190 and $210, respectively.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Zero Yield Aviation Fuel Production 04.12.2022

An interdisciplinary team of researchers at Worcester Polytechnic Institute (WPI) has developed a potential breakthrough in sustainable aviation: a zero-fuel recipe for aircraft that extracts carbon dioxide (CO2) from the air.

Led by Jagan Jayachandran, Associate Professor, Department of Aerospace Engineering, and Adam Powell, Associate Professor, Department of Mechanical and Materials Engineering, the work is helping to address the urgent challenge of climate change. According to the International Council for Clean Transportation (ICCT), aviation is responsible for approximately 2,5% of all global greenhouse gas emissions and this figure is expected to rise.

"As aviation grows, so will industrial emissions," says Powell. "We need to think outside the box and look at sustainable materials that will contribute to a long-term solution to reduce the transport sector's carbon footprint."

Through modeling and computational analysis, Jayachandran and Powell developed a formula for a fuel composed of magnesium, the world's most abundant mineral in the world's oceans. A slurry of magnesium hydride - a chemical compound made up of magnesium and hydrogen - mixed with a hydrocarbon fuel would burn to form CO2, water vapor and magnesium oxide (MgO) nanoparticles.

Magnesium hydride fuel will also provide aircraft with long-haul range, such as from Boston to Tokyo, which is a problem with other sustainable aviation fuels. This greater range is achieved in part due to the chemical properties of the slurry - combustion requires less volume than typical aviation fuel.

"We have found that this fuel will have 8% more range than other modern jet fuels and more than two to three times the range of liquid hydrogen or ammonia that other researchers have proposed as clean fuels." Jayachandran noted.

The Department of Energy describes sustainable aviation fuel as "a biofuel used to power aircraft that has properties similar to conventional jet fuel, but with a lower carbon footprint." This biofuel is produced from resources such as corn grain, algae, forestry and agricultural waste. The use of biofuel as a hydrocarbon in this magnesium hydride slurry can result in net negative emissions.
