A new study into the impact of climate change upon the animal world sends out a warning. This is that time is running out in the tropics, with scientists warning of a global biodiversity collapse.

Bioengineers have worked on a new technique using simple tissue-grafting in order to increase brown fat mass in the human body. Researchers have then looked at the impact of this upon metabolism and weight.

The drug development process is a convoluted process with as many false starts as there are successes. A new research project has shown how artificial intelligence can help to accelerate the process.

Computational photographic methods are being used by archaeologists to help capture the past, where digital process reveal more detail than is possible using conventional equipment. Such finding can help to protect sites of special interest.

NASA’s focus should not be on the cosmos but on Earth, according to a wide-ranging Bloomberg poll of Americans’ views on space.

Caucher Birkar, a Cambridge University professor of Iranian Kurdish origin, on Wednesday was named one of four winners of the prestigious Fields medal, often known as the Nobel prize for mathematics.

X-ray technology, called X-ray polarimetry, has revealed never-before-seen matter around a black hole. The black hole is Cygnus X-1, in the constellation Cygnus, and the first such source widely accepted to be a black hole.

A new artificial intelligence driven platform can assess a person’s personality by scanning the eyes. This is through assessing the way that the eyes move, through the use of an advanced tracker and data analysis software.

The Arctic Circle — the realm of polar bears, caribou and dwindling sea ice at the top of the world — hit 90 degrees Fahrenheit, 32 degrees Celsius, this week.

The world's top mathematicians will convene in Rio de Janeiro on Wednesday to find out the new winners of the Fields Medal, the award often dubbed the Nobel Prize for math.

A new study says terraforming Mars can’t be done “with existing technology”. Well, duh. You don’t say. WIRED and Space.com have fearlessly agreed, stating it can’t be done. So there, nerds, says WIRED.

New concerns have been expressed about the extent of ocean acidification. A new paper finds ocean acidification is becoming a greater challenge for science, governments, and communities to tackle.

Research group FIND has announced a new wave of activities designed to address the challenges threatening hepatitis C elimination. This is through several potential diagnostic technologies.

A new study has found that mobile phone radiation could affect memory performance in adolescents, as evidenced through new tests. This adds weight to other research concerned with radiation emissions from connected technology.

New research draws a connection between the health of an expectant mother's gut and autism in her yet to be born child. The inference that follows is that changing an expectant mother's diet could lower autism risks. However, further research is required.

A innovative technique has been developed to hep to predict cerebral palsy. The technique is based on next-generation genetic sequencing data, which measures how cells control the way genes are switched on or off.

Sixty years ago, spurred by competition with the Soviet Union, the United States created NASA, launching a journey that would take Americans to the moon within a decade.

A massive underground lake has been detected for the first time on Mars, raising hopes that more water -- and maybe even life -- exists there, international astronomers said Wednesday.

AIDS experts called Wednesday for an end to laws that can see HIV-positive people jailed for exposing others to the virus, saying the approach was "unscientific" and worsening the killer epidemic.

The longest "blood moon" eclipse this century will coincide with Mars' closest approach in 15 years to offer skygazers a thrilling astronomical double bill on Friday, astronomers say.

A new material made from substances common in crab shells and tree fibers could replace the flexible plastic packaging used to keep food fresh.
