Thanks to the Contingency Operations program, the military is able to utilize the first GPS III satellite without the next-generation ground segment being built for it. The second GPS III satellite was launched in April, and a third launch is slated for later this year. (Airman 1st Class Dalton Williams/Air Force)

Student debt is over $1.6 trillion and hardly anyone is paying down their loans

Posted by in categories: education, energy

Since the explosion of student debt following the Great Recession, annual repayment rates, or the amount of existing balances lowered, have been just 3%, Moody’s said. Just 51% of borrowers who took out loans from 2010-12 have made any progress at all in paying down their debt.

“While in the past, higher enrollment and rising tuition were the main drivers of growing student loan balances, more recently, slow repayments have become the primary driver,” Jody Shenn, senior analyst at Moody’s, and others said in the report. “Over the next few years, the combination of slow repayments and elevated, if no longer growing, levels of new borrowing will likely fuel further increases in outstanding debt.”

There are multiple reasons why the debt levels are not going down.

SpaceX will trigger an intentional rocket failure to prove crew capsule’s safety

Posted by in category: space travel

SpaceX will sacrifice a Falcon 9 rocket Sunday in a fiery test a minute-and-a-half after liftoff from Florida’s Space Coast to prove the company’s Crew Dragon spacecraft can safely push astronauts away from a failing launch vehicle, simulating a daring maneuver that would only be attempted on a piloted mission during an in-flight emergency.

The launch escape demonstration could be a spectacle for local residents, rocket fans and enthusiasts along the Space Coast, assuming clear skies and good visibility, according to SpaceX.

Posted by in categories: cybercrime/malcode, finance, government


Several Greek government websites fell prey to cyber-attacks on Friday evening, forcing some of them to shut down entirely for security reasons, after access to them became problematic.

Among those attacked by hackers were the websites of the Greek Parliament, the Foreign Affairs Ministry, the Athens Stock Exchange, the National Intelligence Service (EYP) and the Finance Ministry.

A Turkish group named” Phoenix’s Helmets” (Anka Neferler Tim) posted a post on Facebook claiming responsibility for the attacks, in order to respond, as they said, to Athens’ threats against Turkey.

Posted by in categories: cybercrime/malcode, government, privacy

It’s been a lousy week for Windows users: first, the NSA curveball crypto vulnerability and now confirmation of a zero-day vulnerability that’s being actively exploited with no fix yet.

Hot on the heels of National Security Agency (NSA) and Department of Homeland Security’s Cybersecurity & Infrastructure Security Agency (CISA) warnings for Windows 10 users to update urgently as news of the curveball crypto vulnerability broke, here we are again. The CISA has published a new warning for Windows users as Microsoft confirms a critical zero-day vulnerability is being actively exploited, and there’s no fix available at the time of writing.

Cheap drug may alleviate treatment-resistance in leukemia

Posted by in category: biotech/medical

A common and inexpensive drug may be used to counteract treatment resistance in patients with acute myeloid leukemia (AML), one of the most common forms of blood cancer. This is the conclusion of a study in mice and human blood cells performed at Karolinska Institutet and SciLifeLab and published in the medical journal EMBO Molecular Medicine. The researchers will now launch a clinical study to test the new combination treatment in patients.

Leukemia is a group of blood cancers that results in excess amounts of white blood cells. There are both chronic forms of leukemia that progress slowly over many years and acute types of leukemia that evolve rapidly. AML affects more than 20,000 people in the United States each year, and the mortality rate is high especially in .

One of the most common drugs to treat AML is cytarabine (ara-C), a cytotoxic that interferes with DNA replication. However, many patients do not respond to the treatment because their leukemic cells express high levels of the enzyme SAMHD1, which breaks down the active metabolite of cytarabine, ara-CTP. These patients have a significantly worse survival rate than patients with low leukemic levels of SAMHD1. Therefore, one promising strategy to improve the treatment of AML is to inhibit the effects of this enzyme on cytarabine.
