Pluto, the Kuiper belt and the early history of the solar system - Renu.
Δημοσιεύτηκε στις 30 Ιουλ 2015
Our
understanding of the formation of the solar system has undergone a
revolution in recent years, owing to new theoretical insights into the
origin of Pluto and the discovery of the Kuiper belt and its complex
dynamical structure. The emerging picture is one of dramatic orbital
migration of the planets in the early history of the solar system,
driven by interaction with the primordial Kuiper belt, which produced
the final solar system architecture that we live in today. The evidence
is all over the solar system, as close as the Moon and as far away as
Pluto and the remnant Kuiper belt. Dr. Malhotra will review this new
view of our solar system's history, describe the astronomical evidence,
and critically assess current theoretical models.

Everyone 'should take vitamin D pills'
Everyone 'should take vitamin D pills'
Everyone
should consider taking vitamin D supplements to counter the lack of
sunshine in the UK, government experts are proposing.
The draft
Scientific Advisory Committee on Nutrition guidelines suggest, from the
age of one, 10 microgram pills be taken to ensure people get enough.The plans are now being consulted on until 23 September.
Current advice is only at risk groups - including pregnant women, under fives and over 65s - should take supplements.
But as there is no easy way of assessing who is getting enough vitamin D, SACN has proposed a blanket recommendation for everyone because of the benefits it would bring.
The risk of getting too much vitamin D is considered to be extremely low.
HIV flushed out by cancer drug
HIV flushed out by cancer drug
HIV can be flushed out of its hiding places in the body using a cancer drug, researchers show.
The
cornerstone of treatment, anti-retroviral therapy, kills the virus in
the bloodstream but leaves "HIV reservoirs" untouched. The study, published in PLoS Pathogens, showed the drug was "highly potent" at reactivating hidden HIV.
Experts said the findings were interesting, but it was important to know if the drug was safe in patients.
The power of the HIV reservoir was shown with the case of the Mississippi baby.
She was given antiretroviral drugs at birth. Despite appearing to be free of HIV for nearly two years after stopping treatment, she was found to be harbouring the virus.
First 3D-printed pill approved by US authorities
First 3D-printed pill approved by US authorities
In a world first, the US Food and Drug Administration has given the go-ahead for a 3D-printed pill to be produced.
The FDA has previously approved medical devices - including prosthetics - that have been 3D printed.The new drug, dubbed Spritam, was developed by Aprecia Pharmaceuticals to control seizures brought on by epilepsy.
The company said that it planned to develop other medications using its 3D platform.
Printing the drugs allows layers of medication to be packaged more tightly in precise dosages.
A separate technology developed by the firm, known as ZipDose, makes high-dose medications easier to swallow.
Printing the drug meant it could package up to 1,000 milligrams into individual tablets.
The 3D-printed pill dissolves in the same manner as other oral medicines.
