Desert conditions are harsh, and mosses often spend much of the year in a dormant condition, desiccated and brown, until rain comes. Researchers discovered two species of moss that found a hiding place under translucent milky quartz where they can stay moist and green and continue to photosynthesize and grow while other mosses on the soil surface go dormant. This is the first green plant known to
Bacteriophages, or phages, may play a significant role in treating complex bacterial infections in prosthetic joints, according to new research. The findings suggest phage therapy could provide a potential treatment for managing such infections, including those involving antibiotic-resistant microbes.

Existing limited evidence suggests that wearing face coverings to protect against COVID-19 does not lead to a false sense of security and is unlikely to increase the risk of infection through wearers foregoing other behaviours such as good hand hygiene, say researchers from the University of Cambridge and King's College London.
Psilocybin may be safe for treating depression but research is stymied by government controls Potential treatments for severe depression, addiction and other mental health disorders are being held up by excessive restrictions on psilocybin, the active ingredient in magic mushrooms , scientists and politicians have said. Clinical trials suggest that psilocybin may be a safe and effective medicine
Working men with higher incomes are more likely to develop high blood pressure, reports a study presented at the 84th Annual Scientific Meeting of the Japanese Circulation Society (JCS 2020). "Men with higher incomes need to improve their lifestyles to prevent high blood pressure," said study author Dr. Shingo Yanagiya of the Hokkaido University Graduate School of Medicine, Sapporo, Japan.
To get that sunset 'Gram-ready, you'll need more than a filter. ( Cyriac Jannel / Unsplash/) Smartphones have a serious advantage over DSLRs and other dedicated cameras —not only can you shoot great photos, but you can edit and share them too. For a lot of people, editing images with their phone just consists of slapping a filter on and posting the pic to social media. And while that was your onl
Using a simple urine test alongside routine imaging for patients with adrenal masses could speed up adrenal cancer diagnosis, improving patient's prognosis and reducing the need for invasive diagnostic procedures, a new multi-center study found.
Researchers have new insight into the tiny packages that cells use to move molecules, a structure that is key to cellular metabolism, drug delivery and more.
The new base editing platform may help researchers understand and correct genetic diseases by selective editing of single DNA 'letters' across nucleobase classes.
Researchers have discovered a new method to treat human herpes viruses. The new broad-spectrum method targets physical properties in the genome of the virus rather than viral proteins, which have previously been targeted. The treatment consists of new molecules that penetrate the protein shell of the virus and prevent genes from leaving the virus to infect the cell. It does not lead to resistance
Primates with large brains can master more complex hand movements than those with smaller brains. However, fine motor skills such as using tools can take time to learn, and humans take the longest of all. Large-brained species such as humans and great apes do not actually learn more slowly than other primates but instead start later, researchers have shown.
Researchers have developed a system to mold near-field light — opening the door to unprecedented control over this powerful, largely unexplored type of light.

At midnight on 2 August, people around globe will be able to see grouping high in the sky Set a calendar reminder for this coming weekend when an essentially full moon joins Jupiter and Saturn in the southern sky. When full, the moon rises at sunset and spends the entire night in the sky, so the grouping will be visible during all the hours of darkness. The chart shows the view looking due south

Olivia de Havilland was the last great living female star of the movies' golden age, in the 1930s and '40s. She died today at 104 at her home in Paris, and her radiant visage and sinuous voice will haunt audiences for at least another century, whether as Errol Flynn's blushing Maid Marian in The Adventures of Robin Hood , or as her old friend Bette Davis's scheming foil in the Grand Guignol of Hu
Researchers have designed a smart technology that can help utility companies better serve communities affected by power outages. The researchers said their single device works by improving energy delivery between home solar-power systems and the electrical grid.
Researchers have developed a new approach to compare changes in neural communication using electroencephalography and functional magnetic resonance imaging simultaneously. The approach allows them to assess the association between the two measurements and better understand neural connectivity changes over time.

The thalamus is a 'Grand Central Station' for sensory information coming to our brains. Almost every sight, sound, taste and touch travels to our brain's cortex via the thalamus. Researchers now report that the somatosensory part of the thalamic reticular nucleus is divided into two functionally distinct sub-circuits that have their own types of genetically defined neurons that are topographically
Meet PolyA-miner, a new computational tool that enables scientists to evaluate the contribution of alternative polyadenylation to gene regulation in health and disease.
Highly stable polymeric "amyloid" proteins, best known for their role in Alzheimer's disease, have been mostly studied in animals. But a new study on the garden pea shows that they also occur in plants, and they may be an important adaptation for prolonging seed viability.

A day after roaring ashore as a hurricane, Hanna lashed the Texas Gulf Coast on Sunday with high winds and drenching rains that destroyed boats, flooded streets and knocked out power across a region already reeling from a surge in coronavirus cases.
For students heading to Colby College in Maine this fall, coronavirus testing is expected to be a routine part of campus life. All students will be required to provide a nasal swab every other day for two weeks, and then twice a week after that. All told, the college says it will provide 85,000 tests, nearly as many as the entire state of Maine has since the pandemic started.

When Deep Blue defeated world chess champion Garry Kasparov in 1997, it may have seemed artificial intelligence had finally arrived. A computer had just taken down one of the top chess players of all time. But it wasn't to be. Though Deep Blue was meticulously programmed top-to-bottom to play chess, the approach was too labor-intensive, too dependent on clear rules and bounded possibilities to su
Removing carbon dioxide from power plant emissions is ever more urgent to limit the damage from climate change. Chemists have come up with an efficient and less expensive technique for removing CO2 from natural gas plant emissions. The technique could be tweaked for more polluting plants that use coal. The chemists took a magnesium-based metal-organic framework and added a tetraamine that catalyze

Nobody likes getting old . That's why you can walk into any drugstore in the country and find a hundred different "anti-aging" creams, oils, masks, serums, and vitamins. Unfortunately, while many of these products may claim to "reverse the aging process," none of them actually address the underlying cause of aging. If you want to do that, you need products developed by real scientists, not beauty
Given avocado's popularity today, it's hard to believe that we came close to not having them in our supermarkets at all. In my new book " Avocado: A Global History ," I explain how the avocado survived a series of ecological and cultural close calls that could have easily relegated them to extinction or niche delicacy. Instead, the avocado persevered, prospered – and became one of the most Instag
Kanye West, Elon Musk, Bill Gates, and Barack Obama were all feeling generous on the evening of July 16, according to their Twitter accounts, which offered to double any payments sent to them in bitcoin.

"Have you ever met anyone who's read the party platform? I haven't," the former Republican House Speaker John Boehner said during a 2012 interview about his party's manifesto.

It shows how dramatically President Donald Trump has reframed t

However, these masks are costly,
Twitter is perfect as a megaphone for the far right: its trending topics are easy to game, journalists spend way too much time on the site, and—if you're lucky—the president of the United States might retweet you.
