2 sticks of RAM giving you 1TB of memory will be the norm soon.


While consumers today typically use computers with 8GB or 16GB of DDR4 RAM inside, Samsung is pushing ahead with the next generation of memory modules. Its latest stick of RAM is a 512GB DDR5 module running at 7200Mbps.

The new module will be used in servers performing “the most extreme compute-hungry, high-bandwidth workloads.” That means supercomputers, artificial intelligence, and machine learning. It was made possible thanks to advanced HKMG technology, which Samsung adopted back in 2018 for its GDDR6 memory. Basically, HKMG replaces the insulator layer in DRAM structures. The high dielectric material contained in the layer reduces current leakage and therefore allows higher performance. At the same time, Samsung managed to reduce power usage in the new module by 13%.

“Samsung is the only semiconductor company with logic and memory capabilities and the expertise to incorporate HKMG cutting-edge logic technology into memory product development,” said Young-Soo Sohn, Vice President of the DRAM Memory Planning/Enabling Group at Samsung Electronics. “By bringing this type of process innovation to DRAM manufacturing, we are able to offer our customers high-performance, yet energy-efficient memory solutions to power the computers needed for medical research, financial markets, autonomous driving, smart cities and beyond.”

A new map of dark matter in the local universe reveals several previously undiscovered filamentary structures connecting galaxies. The map, developed using machine learning by an international team including a Penn State astrophysicist, could enable studies about the nature of dark matter as well as about the history and future of our local universe.

Dark matter is an elusive substance that makes up 80% of the universe. It also provides the skeleton for what cosmologists call the cosmic web, the large-scale structure of the universe that, due to its gravitational influence, dictates the motion of galaxies and other cosmic material. However, the distribution of local dark matter is currently unknown because it cannot be measured directly. Researchers must instead infer its distribution based on its gravitational influence on other objects in the universe, like galaxies.

“Ironically, it’s easier to study the distribution of dark matter much further away because it reflects the very distant past, which is much less complex,” said Donghui Jeong, associate professor of astronomy and astrophysics at Penn State and a corresponding author of the study. “Over time, as the large-scale structure of the universe has grown, the complexity of the universe has increased, so it is inherently harder to make measurements about dark matter locally.”

Interest in such plush panic rooms is skyrocketing, he said. His firm started offering high-end shelters and the like a decade ago — of the 232 it’s built so far, 200 were commissioned in the last five years.


One $14 million panic-room project built in the San Jose Valley includes a bowling alley and indoor pool.

For thousands of years, humans have used honey, propolis, and venom from the European honeybee Apis mellifera as medicines.

More recently, scientists have discovered that honeybee venom and its active component, melittin, are toxic to a wide range of tumors — including melanoma, lung, ovarian, and pancreatic cancers — in laboratory tests.

Melittin is the molecule that creates the painful sensation of a bee’s sting. Scientists do not fully understand how it kills cancer cells, however.

Engineers have designed a computer processor that thwarts hackers by randomly changing its microarchitecture every few milliseconds. Known as Morpheus, the puzzling processor has now aced its first major tests, repelling hundreds of professional hackers in a DARPA security challenge.

In 2017, DARPA backed the University of Michigan’s Morpheus project with US$3.6 million in funding, and now the novel processor has been put to the test. Over four months in 2020, DARPA ran a bug bounty program called Finding Exploits to Thwart Tampering (FETT), pitting 525 professional security researchers against Morpheus and a range of other processors.

The goal of the program was to test new hardware-based security systems, which could protect data no matter how vulnerable the underlying software was. Morpheus was mocked up to resemble a medical database, complete with software vulnerabilities – and yet, not a single attack made it through its defenses.

In 2019, the European Union banned chlorpyrifos, allowing three more months of use. Canada’s three-year phaseout risks ongoing harms, as well as dumping of this product on our market.

Back in 2000, Canadian politicians spoke up against commonly used lawn and household chlorpyrifos products when the U.S. banned domestic uses. Despite a year of study, the PMRA had not taken action.

How long will chlorpyrifos persist in commerce?
