Scientists discover biomarker for flu susceptibility



Posted: 13 Jun 2018 05:52 PM PDT


Researchers have found a way to predict whether someone exposed to the flu virus is likely to become ill. They used a computational approach to pinpoint a blood-based genetic biomarker to determine an individual's susceptibility to the disease.


Decades of satellite monitoring reveal Antarctic ice loss



Posted: 13 Jun 2018 01:30 PM PDT


Scientists have reviewed decades of satellite measurements to reveal how and why Antarctica's glaciers, ice shelves and sea ice are changing. Their report explains how ice shelf thinning and collapse have triggered an increase in the continent's contribution to sea level rise.


Antarctica ramps up sea level rise



Posted: 13 Jun 2018 01:30 PM PDT


Ice losses from Antarctica have increased global sea levels by 7.6 mm since 1992, with two fifths of this rise (3.0 mm) coming in the last five years alone. The findings are from a major climate assessment known as the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE). It is the most complete picture of Antarctic ice sheet change to date -- 84 scientists from 44 international organizations combined 24 satellite surveys to produce the assessment.


Climate change accelerating rise in sea levels



Posted: 13 Jun 2018 01:30 PM PDT


A new study has discovered that rising sea levels could be accelerated by vulnerable ice shelves in the Antarctic.


Ancient agricultural activity caused lasting environmental changes



Posted: 13 Jun 2018 01:30 PM PDT

Ammonia distribution in Earth's upper atmosphere



Posted: 13 Jun 2018 01:28 PM PDT


A new study helps clarify how ammonia is present in Earth's upper atmosphere. Using computer modeling, the researchers found ammonia molecules trapped in liquid cloud droplets are released during convection where these particles freeze and subsequently collide in the upper atmosphere.


For 100 million years, amber freezes a tableau of tick's worst day ever



Posted: 13 Jun 2018 01:27 PM PDT


This is the first time this kind of interaction between ticks and spiders has been documented in the fossil record. Even though ticks aren't a typical staple of spider diets, spiders can occasionally prey on ticks in modern ecosystems.


Lentils significantly reduce blood glucose levels



Posted: 13 Jun 2018 01:27 PM PDT


Replacing potatoes or rice with pulses can lower your blood glucose levels by more than 20 per cent, according to a new study. Researchers found that swapping out half of a portion of these starchy side dishes for lentils can significantly improve your body's response to the carbohydrates. Replacing half a serving of rice with lentils caused blood glucose to drop by up to 20 per cent. Replacing potatoes with lentils led to a 35-per-cent drop.


Cannabis does not increase suicidal behavior in psychiatric patients



Posted: 13 Jun 2018 01:26 PM PDT


Researchers have found there is no significant association between cannabis use and suicidal behavior in people with psychiatric disorders. The study findings contrast with pre-existing data that shows the drug is linked to an increased chance of suicidal behavior in the general population.


Stress test to predict how diatoms will react to ocean acidification



Posted: 13 Jun 2018 01:26 PM PDT


Researchers have shown that diatoms can withstand population collapse in an acidified environment by conserving valuable energy normally used for carbon dioxide consumption.


Attacking bacteria with shark skin-inspired surfaces



Posted: 13 Jun 2018 08:37 AM PDT


Sharks are often the subject of TV specials or news stories focusing on their attacks on humans. But scientists are finding that sharks could inspire a new type of surface that would attack bacteria, helping humans instead of hurting them. Researchers have designed a coating that is infused with antimicrobial agents and has the patterned diamond-like texture of shark skin.


Large-scale whaling in north Scandinavia may date back to 6th century



Posted: 13 Jun 2018 08:37 AM PDT


The intensive whaling that has pushed many species to the brink of extinction today may be several centuries older than previously assumed.


Mediterranean-style eating with lean, unprocessed red meat improves heart disease risk



Posted: 13 Jun 2018 08:37 AM PDT


Adopting a Mediterranean-style eating pattern improves heart health, with or without reducing red meat intake, if the red meat consumed is lean and unprocessed, according to a new nutrition study.


Deadly fungus found for first time in critically endangered amphibian species



Posted: 13 Jun 2018 08:37 AM PDT


A fungal pathogen which has led to the extinction of entire species in South America has been recorded for the first time in critically endangered amphibians in India.


Environmental threats put bumblebee queens under pressure



Posted: 13 Jun 2018 08:36 AM PDT


Researchers found that environmental threats are piling onto the stress faced by nest-building bumblebee queens.


Old Man River's unique chemical signature



Posted: 13 Jun 2018 08:36 AM PDT


Human activity greatly impacts the natural chemistry of the largest river in North America -- the Mississippi River. In a new, large-scale study, geologists have identified a unique chemical signature in the river.


High-protein corn also resistant to parasitic weed



Posted: 13 Jun 2018 07:20 AM PDT


In sub-Saharan Africa, 20 to 80% of corn yields may be lost because of a semi-parasitic plant, Striga. In areas infested with Striga, farmers may even lose their entire crops. In a new study, researchers from southern Africa identified several varieties of corn resistant or tolerant to Striga. Importantly, these varieties also have improved nutritional content, particularly protein.


Floridians took Zika threat more seriously than rest of US -- but still most did nothing



Posted: 13 Jun 2018 07:20 AM PDT


Threatened by the mosquito-borne Zika virus in 2016, Florida residents felt more susceptible than others in the United States to getting the virus, were more knowledgeable about it, and were more likely to support taking community action against it. Floridians were nearly twice as likely as non-Floridians to say they took steps to protect themselves from Zika. Even so, fewer than half of Floridians said they actually did take preventive measures.


Observing the cell's protein factories during self-assembly



Posted: 13 Jun 2018 07:20 AM PDT


Researchers have produced snapshots of the 'protein factories' of the cell. Their findings could set us on the path towards a new class of antibiotics.


Scientists discover a new way to find mass extinctions



Posted: 13 Jun 2018 07:20 AM PDT


During the history of the Earth, there were many mass extinctions, when huge numbers of species died out. They are usually easy to identify because of the sudden extinctions, followed by a gap, and then the recovery of life.


Large fenced reserves an effective way to bring wolves back to Scotland



Posted: 13 Jun 2018 07:20 AM PDT


Research indicates that for wolves to be effective at directly reducing red deer numbers and allowing nature to recover in the Scottish Highlands they may need to be reintroduced to very large fenced reserve.


Painted lady's roundtrip migratory flight is the longest recorded in butterflies



Posted: 13 Jun 2018 07:20 AM PDT


Researchers found that painted lady butterflies return from the Afrotropical region to recolonize the Mediterranean in early spring, traveling an annual distance of 12,000 km across the Sahara Desert.


British mammals' fight for survival



Posted: 13 Jun 2018 07:20 AM PDT


Almost one in five of British mammal species face a high risk of extinction, according to a recent comprehensive review of their populations.


Original habitat is best, but restoration still makes a big difference



Posted: 13 Jun 2018 07:19 AM PDT


A new study presents some of the best evidence to date that restoration efforts in Missouri's Ozark Highlands make a difference for nesting songbirds that breed there. Recent studies support that these efforts are making a positive impact on the ecosystem and increasing the survival of bird species that breed there.


Magnetic treatment could help remove 'off-flavor' from wines



Posted: 13 Jun 2018 07:19 AM PDT


From vine to wine, grapes undergo a remarkable transformation. But sometimes this makeover results in vino that doesn't taste quite right. Scientists now report that they have found a way to use tiny magnetic particles to remove off-tasting substances in cabernet sauvignon without altering its desired bouquet. Eventually, they say this technique could help remove unwanted flavors from other wines.


To forecast winter rainfall in the Southwest, look to New Zealand in the summer



Posted: 13 Jun 2018 07:19 AM PDT
