An intense blast of energy that was detected on Earth appears to have come from two colliding and collapsing stars, according to scientists.
Researchers looking through archival observations of gamma rays say they have found “oscillating” signals in two bursts of energy.
They were found in old data taken from an out-of-use experiment in orbit around Earth.
Worried about a blackout during extreme weather? San Francisco-based EcoFlow Tech offers a battery backup system that can now power your home for an entire week and this includes heavy appliances like washing machines, coffee machines, and hairdryers too. The system is completely portable and can also be used to power your RV during an off-road trip.
Energy solutions such as Tesla Powerwall, which can be recharged using energy from sunlight but EcoFlow Tech is taking it a step further by delivering a power backup system that is entirely portable.
Under normal temperature and pressure conditions, the reactor could efficiently convert plastic bottles and CO2 into CO, syngas, and glycolic acid.
Researchers from the University of Cambridge developed a first-of-its-kind system that can simultaneously convert plastic waste and greenhouse gases into two chemical products by drawing energy from the sun.
The results are reported in the journal Nature Synthesis.
Apple today shared an update on its subscription businesses and global App Store, noting that the tech company has now paid out a record $320 billion to app developers since 2008 — a number that reflects the revenue apps have generated, minus Apple’s commission. In addition, the tech giant said it now has more than 900 million paid subscriptions across Apple services, with subscriptions on the App Store driving a “significant” part of that figure.
The company’s App Store in 2022 faced one of its tougher years since its founding, with lawsuits and antitrust actions aimed at limiting its market power.
The satellite had an expected two-year-service life, but it blew past that mark. “For 21 of its years in orbit, the ERBS actively investigated how the Earth absorbed and radiated energy from the Sun, and made measurements of stratospheric ozone, water vapor, nitrogen dioxide, and aerosols,” NASA said.
Spacefaring machines that come back to Earth are subject to an intense reentry process. NASA expected most of ERBS to burn up, “but for some components to survive the reentry.” The return trajectory over a body of water means anything that wasn’t toast likely fell harmlessly into the sea.
The satellite’s uneventful fall back to its home planet is a bit of good news at a time when orbital space is increasingly crowded with junk, debris and defunct satellites. ERBS went out in a blaze of glory after its distinguished service to science.
A powerful solar flare hit Earth last week, causing a radio blackout over parts of Australia and the South Pacific last week, CNET reported. This is one of the most powerful flares seen since October last year and might be a sign of what is coming next.
A solar flare is an eruption of electromagnetic radiation from the Sun’s surface. According to the European Space Agency, flares occur when energy stored in magnetic fields on the solar surface is suddenly released.
They can be your power source on the go.
A startup named LAND Energy offers its customers something that most companies don’t. The option to swap the batteries on the vehicle, keeping the vehicle brand new even as technology improves over the years.

The glow-in-the-dark pavement is charged by the sun during the day and emits its own light for up to 10 hours at night, eliminating the need for energy-consuming street lights. The glow-in-the-dark pavement is just the first stage of many potential projects engineers are testing to make roadways safer and more energy efficient.
Everyone is concerned when driving on a dark road if the road markers are not clearly visible or if the lighting is insufficient. Fortunately, Tarmac Linemarking, an Australian firm that works with OmniGrip and Vicroads, has made a fresh breakthrough by generating glow-in-the-dark road markings that resemble children’s toys. According to a report by News.com.au published on Thursday. The test was conducted on a one-kilometer section of the Metong Road in Victoria’s southeast and images were posted on Facebook.
Princeton Engineering researchers have developed a cost-effective way to use breakfast foods to create a material that can remove salt and microplastics from seawater.
The researchers used egg whites to create an aerogel, a versatile material known for its light weight and porosity. It has a range of uses, including water filtration, energy storage, and sound and thermal insulation. Craig Arnold, the Susan Dod Brown Professor of Mechanical and Aerospace Engineering and vice dean of innovation at Princeton, leads a lab that focuses on creating new materials, including aerogels, for engineering purposes.
One day, sitting in a faculty meeting, he had an idea.
A study demonstrates full energy–momentum matching, and enhanced interaction, between free electrons and photons through a continuum of flatband resonances, realized in a silicon-on-insulator photonic crystal slab.
