Dawn on Ceres: Nasa probe to enter dwarf planet's orbit

First rendezvous with the largest object in the asteroid belt separating Mars from Jupiter will reveal what Ceres is made of Nasa scientists are making final preparations for a spacecraft to begin the first orbits around a dwarf planet in the planetary rubble on the far side of Mars. Almost eight years after blasting off from Cape Canaveral in Florida, and travelling 3bn miles (4.8bn km),

Astronauts take third spacewalk to finish tricky cable job at station

How hunting with wolves helped humans outsmart the Neanderthals

Forty thousand years ago in Europe our ancestors formed a crucial and lasting alliance that enabled us to finish off our evolutionary cousins, the NeanderthalsDogs are humanity’s oldest friends, renowned for their loyalty and abilities to guard, hunt and chase. But modern humans may owe even more to them than we previously realised. We may have to thank them for helping us eradicate our caveman

Why racism is not backed by science

As we harvest ever more human genomes one fact remains unshakeable: race does not existBarely a week goes by without some dispiriting tale of racism seeping into the public consciousness: the endless stream of Ukip supporters expressing some ill-conceived and unimaginative hate; football hooligans pushing a black man from a train. I am partly of Indian descent, a bit swarthy, and my first exper

Starwatch: The March night sky

If we have neglected to prepare for the solar eclipse on the morning of 20 March, there should still be time. It is probably too late, though, to find accommodation on the Faroe Islands or Svalbard which have the only land on the path of totality, from which the Moon obscures the Sun completely. Britain, and particularly Scotland, is well placed to enjoy a deep partial eclipse with 87% of the Su

Cédric Villani: ‘Mathematics is about progress and adventure and emotion’

Fields medal winner Cédric Villani is an impassioned advocate for mathematics, as Carole Cadwalladr discoversThe second time I meet Cédric Villani is when I bump into him in the Eurostar terminal in Paris. But then how could I miss him? There are crowds of milling businessmen and weekending couples but there, amid the Sunday-night chaos of the Gare du Nord, is a figure who looks like he’s someh

Why do we care about the colour of the dress?

An optical illusion has proved divisive on social media. But our varying perceptions mean we will find it hard to come to an agreementIt is rare, other than on Oscars night, that the world holds its collective breath discussing dresses and their colours.

Global warming slowdown probably due to natural cycles, study finds

Manmade warming in past decade has likely been offset by cooling from natural cycles in the Pacific and Atlantic - but effect will reverse in coming decadesManmade global warming over the past decade has probably been partly offset by the cooling effect of natural variability in the Earth’s climate system, a team of climate researchers have concluded.The finding could help explain the slow

Plantwatch: Snowdrops are in their element

The cold weather hasn’t helped bring on spring flowers, but lesser celandines are coming into bloom, especially in southern England. These relatives of buttercups have glossy yellow flowers and heart-shaped leaves, and the flowers also have the uncanny knack of swivelling round to track the sun like little solar energy dishes, trapping the sun’s warmth to entice early insects into the flower; bu

Birth of a Theorem: A Mathematical Adventure by Cédric Villani – review
