Breakthrough: Instant Computer Memory
I.B.M. has solved two related problems with phase-change memory and now says the next-generation data-storage technology will be ready for use in 2016 in servers.
What's the Latest Development?
Research into phase-change technology has yielded a computer chip that is 100 times more powerful than the current flash memory used in most computers and servers. Whereas consumer electronics prioritize the cost per bit ratio, the new chip would primarily target the server market where speed is paramount. "Our main application, being in the server business, is enterprise storage and memory applications," says I.B.M.'s Haris Pozidis. "Phase-change memory records data through heat changes in the electrical properties of a tiny patch of the glasslike chalcogenide material."
What's the Big Idea?
Phase-change research is, by now, decades old, but recent advances indicate it may be a promising avenue in which to pursue further technological innovation. "I.B.M.'s phase-change memory (P.C.M.) technology isn't yet ready for real-world use, but the improvements in multilevel storage and drift tolerance means the technology should be competitive in 2016 for the server applications I.B.M. has in mind." The technology, however, is making gains in other markets with different requirements, like Samsung mobile phones, which uses P.C.M. instead of flash memory.
Pfizer's partnerships strengthen their ability to deliver vaccines in developing countries.
- Community healthcare workers face many challenges in their work, including often traveling far distances to see their clients

- Pfizer partnered with AMP and the World Health Organization to develop a training program for healthcare workers.
A study on flies may hold the key to future addiction treatments.
- A new study suggests that drinking alcohol can affect how memories are stored away as good or bad.
- This may have drastic implications for how addiction is caused and how people recall intoxication.
- The findings may one day lead to a new form of treatment for those suffering from addiction.
A glass of juice has as much sugar, ounce for ounce, as a full-calorie soda. And those vitamins do almost nothing.
Quick: think back to childhood (if you've reached the scary clown you've gone too far). What did your parents or guardians give you to keep you quiet? If you're anything like most parents, it was juice. But here's the thing: juice is bad for you.
As the world gets hotter, men may have fewer and fewer viable sperm
- New research on beetles shows that successive exposure to heatwaves reduces male fertility, sometimes to the point of sterility.
- The research has implications both for how the insect population will sustain itself as well as how human fertility may work on an increasingly hotter Earth.
- With this and other evidence, it is becoming clear that more common and more extreme heatwaves may be the most dangerous aspect of climate change.
