New Class Of Commercial Herbicide Is All Natural - But Discovered Using Science

Science 2.0 - Jul 16 2018 - 16:07
Nature is not just out to kill us, it is out to kill itself, in the interest of surviving over the long term. That is why even the most wholesome backyard organic garden is a hotbed of combat between plants and unseen microorganisms in the soil fighting for space to grow.

To defeat a plant, a microbe might produce and use toxic chemicals - but then the microbe also needs immunity from its own poisons. The genes that create protective shield in microorganisms could become a new, highly effective weed killer and the first new class of commercial herbicides in more than 30 years.

Bees: It's The Viruses That Are The Problem

Science 2.0 - Jul 16 2018 - 11:07

While environmentalists raise millions of dollars insisting they will get targeted pesticides (e.g. neonicotinoids) banned to save bees that aren't really in peril, science is looking at things which do actually put bees at risk.

At the top of the list is not pesticides, it's nature. An international team has discovered evidence of 27 previously unknown viruses in bees, which could help scientists design strategies to prevent the spread of viral pathogens among these important pollinators.

A Beautiful New Spectroscopy Measurement

Science 2.0 - Jul 16 2018 - 05:07
What is spectroscopy ? 
(A) the observation of ghosts by infrared visors or other optical devices
(B) the study of excited states of matter through observation of energy emissions

If you answered (A), you are probably using a lousy internet search engine; and btw, you are rather dumb. Ghosts do not exist. 

Otherwise you are welcome to read on. We are, in fact, about to discuss a cutting-edge spectroscopy measurement, performed by the CMS experiment using lots of proton-proton collisions by the CERN Large Hadron Collider (LHC).

Intermittent Fasting Fad May Increase Diabetes Risk

Science 2.0 - Jul 15 2018 - 14:07

Intermittent fasting - fasting every other day - is guaranteed to lose weight in the short term, because it's a crash diet. 

But like lots of other fad diets, the people selling books about it are basing their speculation on animal models and an unrealistic amount of optimism. In biological reality, intermittent fasting impairs the action of sugar-regulating hormone, insulin, which may increase diabetes risk.

Findings presented in the spring at at the European Society of Endocrinology annual meeting, suggest that fasting-based diets may be associated with long-term health risks and careful consideration should be made before starting this fad program - or any fad diet. Energy balance is the only known way to lose weight.

Maybe The Oumuamua Asteroid Is Really A Comet

Science 2.0 - Jul 14 2018 - 10:07
The asteroid Oumuamua ("scout from the distant past" in Hawaiian) was discovered on October 19, 2017 by astronomers at thr Pan-STARRS1 survey when it came close to Earth's orbit, within the orbit of Mercury, about a month after its closest approach to the Sun It was called an asteroid - but it may be a comet.

Why the confusion? There are more data about its trajectory. Oumuamua was unlike any asteroid or comet observed before. It sped past the Sun, approaching from "above" the plabe of the planets on a highly inclined orbit, moving fast enough (70,800 miles per hour as of July 1, 2018) to escape the Sun's gravitational pull and eventually depart our Solar System.

Multiple Barriers To Treatment For Opioid Users

Science 2.0 - Jul 13 2018 - 13:07
In 2016, more than 42,000 Americans died of an opioid-related overdose, which is alarming - but most of those deaths were not accidents by pain patients or suicides, they were recreational drug users.

There are numerous obstacles to making meaningful progress. For one, legitimate pain patients have become more stigmatized - government is blaming doctors and pharmacy rather than drug dealers - and that means people who want to kick their addiction are even more ostracized.

Paleontology Challenge: Zombie Fossils

Science 2.0 - Jul 13 2018 - 09:07

A key part of palaeontology is reconstructing long-extinct creatures to understand what they were like when they were alive. Such knowledge allows us to answer fundamental questions about how they moved and interacted with their environment. How did they feed and reproduce? Which of today's organisms are they most like and most closely related to? 

It has challenges. The history of life can be distorted by the ways animals decompose and lose body parts as they decay - and the ways in which decayed bodies ultimately become fossilized. Like on-screen zombies in "The Walking Dead" that gradually deteriorate through time, fossils preserve only incomplete remains of the living body.

Sea Level Rise Threatens UK Coastal Wetlands By 2100

Science 2.0 - Jul 12 2018 - 18:07
A new analysis estimates that if greenhouse gas emissions continue unabated, sea-level rise will endanger coastal wetlands across the United Kingdom.

That conclusion was derived by estimating salt-marsh vulnerability using the geological record of past losses in response to sea-level change. Data from 800 salt-marsh soil cores showed that rising sea levels in the past led to increased waterlogging of the salt marshes in the region, killing the vegetation that protects them from erosion.

Milky Way Galaxy 1 - 0 Sausage Galaxy

Science 2.0 - Jul 12 2018 - 15:07
A cosmic crash 8 billion to 10 billion years ago was a defining event in the early history of the Milky Way and reshaped the structure of our galaxy.

The Sausage Galaxy lost and the Milky Way won, fashioning both its inner bulge and its outer halo. The wreckage is all around us and the paths of the stars from the galactic merger earned them the moniker "the Gaia Sausage."

New Vaccines Instead Of Antibiotics As Approach To Treating Infectious Diseases

Science 2.0 - Jul 12 2018 - 11:07
Enterotoxigenic Escherichia coli is a major cause of diarrhea in developing countries, and responsible for at least 300,000 deaths a year, according to the World Health Organization.

Effective vaccines have not been developed, so patients infected are treated with antibiotics and supporting measures. The emergence of multidrug-resistant bacteria has become a concern so the development of new treatment methods is ongoing.
