The president of the Royal Society calls on the government to guarantee the residency of EU citizens in the UK.
The UK government has set a world-leading climate change target up to the early 2030s.
The Rosetta probe will be crash-landed on Comet 67P on Friday 30 September, the European Space Agency has confirmed.
Human disturbances are putting the Amazon rainforest at greater risk of fire, say researchers.
Sir Paul Nurse says UK science will suffer unless any post-Brexit agreement allows the free movement of people.
The UK Science Minister, Jo Johnson, says that world class research will "endure" following the Brexit.
Scientists in Switzerland have created a robotic salamander that mimics the gait of the ancient amphibian in great detail.
Two wings from birds that lived alongside the dinosaurs have been found preserved in amber.
Scientists say they have found a large helium gas field in Tanzania, amid concerns global supplies are running out.
UK science must fight to make sure it is not an after-thought as Britain renegotiates its relationship with the EU, say research leaders.

Parents and society shouldn't shift the blame for young people's sexual behavior on what teens supposedly see and read in the media about intimate encounters. So says a researcher who led a thorough systematic analysis of 22 relevant studies on the topic.
You might not want to depend on your smartphone app alone to help you avoid or achieve pregnancy, say the authors of a new study. A review of nearly 100 fertility awareness apps finds that most don't employ evidence-based methodology.
Fruit flies may seem simple, but these common visitors to the fruit bowl can drastically alter their gene expression and metabolism to respond to temperature changes in their environment, an international team of researchers have shown. The finding is important because understanding how insects tolerate changes in temperature is a crucial step in protecting and controlling insects worldwide, say researchers.
Free radicals cause cell damage and death, aging and disease, and scientists have sought new ways to repel them for years. Now, a new study outlines the discovery of a protein that acts as a powerful protectant against free radicals.
New therapies are improving care, but early diagnosis remains critical in the effective treatment of invasive, a potentially deadly fungal infection, according to new guidelines.

Flux towers are equipped with inlets for "sniffing the air " above the forest, in addition to other instruments such as sonic anemometers for measuring wind.
For the first time, scientists have been successful in measuring the processes by which an entire forest "breathes," using sophisticated technology involving flux towers and new instrumentation that can precisely measure two different types (isotopes) of carbon dioxide in the air. A team led by Richard Wehr and Scott Saleska at the University of Arizona obtained detailed long-term measurements of the respiration and photosynthesis rates of a temperate deciduous forest during the day and the night.

Gene drive technologies may one day help alleviate the burden caused by diseases transmitted by mosquitoes and other animal vectors.
The BioScience Talks podcast features discussions of topical issues related to the biological sciences.

Tumor DNA is cluttered with genomic alterations, the vast majority of which have little or no functional or clinical relevance. This means that even when cancer researchers discover an alteration in a tumor or a line of cancer cells, the alteration may or may not be relevant to the progression of the disease - chances are good (and history has shown) that many alterations that are correlated with cancer are not causative of cancer; many alterations are "passengers" rather than "drivers". A University of Colorado Cancer Center study published in the journal Cancer Research demonstrates a novel method for sorting passenger from driver alterations, and uses this method to pinpoint a new driver and potential therapeutic target in cancer progression, GON4L.

The GWAS results for genes that influence flowering dates. The known genes Hd1, Hd2, and Hd6 were located, together with two newly-identified genes that also affect flowering dates.
A Japanese research team have applied a method used in human genetic analysis to rice and rapidly discovered four new genes that are potentially significant for agriculture. These findings could influence crop breeding and help combat food shortages caused by a growing population. The paper was published on June 21, 2016 (Japan Standard Time) in the online edition of Nature Genetics.

Infertility affects about 15 percent of couples around the world. A couple's fertility depends on both the female's and male's ability to reproduce, which relies on thousands of genes working properly. In the male mouse, more than 1,000 genes are predominantly expressed in the testis, but their particular functions in reproduction are still a mystery. In a report published today in the Proceedings of the National Academy of Sciences, researchers from Baylor College of Medicine, Osaka University, University of Oulu and the Wellcome Trust Sanger Institute have discovered that 54 of the mouse testis-enriched genes, that also are expressed in humans, are not necessary for male fertility.
