Last year, Princeton researchers identified a disturbing security flaw in which hackers could someday exploit internet-connected appliances to wreak havoc on the electrical grid. Now, the same research team has released algorithms to make the grid more resilient to such attacks.

In a paper published online in the journal IEEE Transactions on Network Science and Engineering, a team from Princeton’s Department of Electrical Engineering presented algorithms to protect against potential attacks that would spike demand from high-wattage devices such as air conditioners—all part of the “internet of things”—in an effort to overload the power grid.

“The cyberphysical nature of the grid makes this threat very important to counter, because a large-scale blackout can have very critical consequences,” said study author Prateek Mittal, an associate professor of electrical engineering.

Being able to accurately forecast how much solar energy reaches the surface of the Earth is key to guiding decisions for running solar power plants.

While day-ahead forecasts have become more accurate in recent years, the solar community lacks a unified verification procedure, and assessing how one forecast compares to another is difficult. New work in the Journal of Renewable and Sustainable Energy looks to provide a standard of reference to the field.

Researcher Dazhi Yang proposed an improved way to assess day-ahead solar forecasting. The proposed method combines two popular reference methods for weather forecasting, namely persistence and climatology. Using a weighted linear combination of both methods, his approach provides a new way to gauge the skill of a forecaster.

IBM has a fleet of quantum computers. That much is fairly well known since IBM has been actively promoting quantum computing for several years. But IBM’s quantum story will get all the more interesting next month, when a 53 qubit computer joins the line, making it the most powerful quantum computer available for use outside IBM.

“Next month, IBM will make a 53-qubit quantum computer available to clients via its Q Network quantum cloud computing service,” said Bits&Chips. That network, said Asian Scientist Magazine, and grew into an “ecosystem of Fortune 500 companies, start-ups, universities and national research labs.”

The first issue of Nature was published in November 1869. That makes 2019 our 150^th anniversary year. The history of Nature mirrors how science and its role in society have changed over that time. Here, we are collecting articles that reflect the past, present and future of Nature, as well as that of the global research community we serve.

The effects of Artificial Intelligence (AI) technologies have already been experienced by the people globally and the increasing utilization of technology has proven a revolutionary advancement in the current scenario of digitization. Knowledge reasoning, planning, machine learning, robotics, computer vision, and graphics are few of the most commonly used areas where the AI has exposed the potential to ease the result oriented operations. In addition to the above, the most common machinery i.e. smartphones are even now available with high-end AI rich features and functionalities. AI enabled smartphones can now be noticed in terms of learning the continued user behavior and applying the same itself, improved security of rich features and enhanced voice assistants exhibiting AI rich functionalities. However, the exposure of Artificial Intelligence like broadest technologies must not be limited up to improved machinery rich features along with process optimization and automation. There are the other best set of fields predicted to get benefit under the global hug of AI worldwide which are hereby mentioned below.

The need to make some hardware systems tinier and tinier and others bigger and bigger has been driving innovations in electronics for a long time. The former can be seen in the progression from laptops to smartphones to smart watches to hearables and other “invisible” electronics. The latter defines today’s commercial data centers—megawatt-devouring monsters that fill purpose-built warehouses around the world. Interestingly, the same technology is limiting progress in both arenas, though for different reasons.

The culprit, we contend, is the printed circuit board. And the solution is to get rid of it.

Our research shows that the printed circuit board could be replaced with the same material that makes up the chips that are attached to it, namely silicon. Such a move would lead to smaller, lighter-weight systems for wearables and other size-constrained gadgets, and also to incredibly powerful high-performance computers that would pack dozens of servers’ worth of computing capability onto a dinner-plate-size wafer of silicon.

Using genetic sequencing, University of California San Diego School of Medicine researchers have identified a principal cellular player controlling HIV reproduction in immune cells which, when turned off or deleted, eliminates dormant HIV reservoirs.

“This is one of the key switches that the HIV field has been searching for three decades to find,” said Tariq Rana, PhD, professor of pediatrics and genetics at UC San Diego School of Medicine. “The most exciting part of this discovery has not been seen before. By genetically modifying a long noncoding RNA, we prevent HIV recurrence in T cells and microglia upon cessation of antiretroviral treatment, suggesting that we have a potential therapeutic target to eradicate HIV and AIDS.”

HIV spreads through certain bodily fluid attacking the immune system and preventing the body from fighting off infections. If left untreated, the virus leads to the disease AIDS.
