Fast Radio Bursts (FRBs) are millisecond-long bursts of radiation recorded on radio waves. They are extremely powerful - for example, during one of the brightest flashes lasting five milliseconds, as much energy is radiated as our Sun generates in a month. The scale of the phenomenon is difficult to imagine. A new study tracks down their source.

HIV normally uses the CCR5 co-receptor to help it infect immune cells, but the receptor’s Δ32 variant effectively blocks viral entry but a 14-month success story using cord blood containing an HIV-resistance gene variant called CCR5Δ32 means HIV has been cured in a patient.

If you watched film and television from an alien spacecraft, you'd wonder how the same government that created a CDC which needs 6 weeks to tell the public that lettuce has E. coli on it can also create "Mission Impossible" plots and shows where FBI agents win every time.

The first part is real, the last is certainly fiction. A new study finds that not only is a government database wrong, it is wrong to an extent that is worrisome when we want people to have more trust in law enforcement agencies. 

Protection of personal data in the Internet Age is a big worry but solutions may be lacking. A smartwatch may seem secure, but the neural network processing that health information is using private data that could still be stolen by a malicious agent through a side-channel attack - one in which secret information is gathered by indirectly exploiting a system or its hardware. In one type of side-channel attack, a hacker could monitor fluctuations in the device’s power consumption while the neural network is operating to extract protected information that “leaks” out of the device.

Though there are examples of fit older men, they are the exception, just as attractive young people are the exception. Yet in youth people just accept that, while in middle age men seem to take it more to heart, lowering their feelings of self-worth.

In youth, attractiveness can be dismissed as genetics. Later on it becomes inevitable due to age.

Some people believe the immune system is dormant when you are healthy and only kicks into action when a threat is present.

Biologically, nature is always trying to kill things, we are just evolved enough to dismiss most without issues, but your immune system is working even when you feel fine. A recent paper highlights how the immune system even causes the liver of the healthy body to produce an energy source called ketone bodies and how that takes place by letting the liver burn fat during fasting.
