Scientist Say Human Evolution Slower Than Thought

Humans may be evolving a third as slowly as commonly thought, according to an investigation into genetic changes in two generations of families.

The genetic code comprises six billion nucleotides, or building blocks of DNA, half of which come from each parent.

Scientists Find Genes Linked to Migraines

Scientists have uncovered a trio of genes tied to migraine headaches, including one in which the link is exclusive to women, according to a new study.

Migraines are acutely debilitating headaches -- sometimes with an "aura", in which patients have the impression of seeing through frosted glass -- that strike up to 20 percent of the population.

Say Goodbye to Cool Summers!

By 2050, the coolest summers in the tropics and parts of the northern hemisphere will still be hotter than the most scorching summers since the mid-20th century if global warming continues apace, according to a new study.

Tropical regions in Africa, Asia and South America could see "the permanent emergence of unprecedented summer heat" even within the next decades, said the study, to be published later this month in the journal Climatic Change Letters.

NASA Says Solar System Edge 'Bunches' in Magnetic Bubbles

A pair of NASA probes wandering in deep space discovered that the outer edge of the solar system contains curious magnetic bubbles and is not smooth as previously thought, astronomers said Thursday.

The NASA Voyager twin spacecraft, which launched in 1977, are currently exploring the furthest outlays of the heliosphere, where solar wind is slowed and warped by pressure from other forces in the galaxy, the U.S. space agency said.

2 New Elements Officially Added to Periodic Table

They exist for only seconds at most in real life, but they've gained immortality in chemistry: Two new elements have been added to the periodic table.

The elements were recognized by an international committee of chemists and physicists. They're called elements 114 and 116 for now — permanent names and symbols will be chosen later.

New Mega-Telescope Unveils Stunning Images

A new telescope designed to map the stars in unprecedented detail has delivered astonishing images in its trial run, the European Southern Observatory (ESO) said on Wednesday.

The VLT Survey Telescope, or VST, has been built on a mountain top in northern Chile's Atacama Desert, benefitting from viewing conditions in one of the driest and least light-polluted places on Earth.

'Dramatic' Solar Flare Could Disrupt Earth Communications

An unusual solar flare observed by a NASA space observatory on Tuesday could cause some disruptions to satellite communications and power on Earth over the next day or so, officials said.

The potent blast from the Sun unleashed a firestorm of radiation on a level not witnessed since 2006, and will likely lead to moderate geomagnetic storm activity by Wednesday, according to the National Weather Service.
