Assessments of climate change on species’ ranges need to account for observations across the full extent of species’ latitudinal and thermal limits and explicitly test for interactions with other global change drivers.
This type of assessment is important for determining threat statuses for species, such as International Union for Conservation of Nature (IUCN) Red List of Threatened Species (see here to look at an assessment done for the Rusty Patched Bumbebee).
These assessments are also important for planning conservation actions as part of initiatives like the U.S. Department of Agriculture and Environmental Protection Agency's Pollinator Health Task Force, which was established to "[promote] the health of honey bees and other pollinators (including birds, bats, butterflies, and insects)".
-
Neonicotinoid effects known from individual and colony levels certainly contribute to pollinator declines and could degrade local pollination services.
This was shown again in some recent 2017 studies, find out more in this Science Perspectives piece.

SST and the maximum potential hurricane intensity
According to a CBS News article from 2017:
Numerous studies have "confirmed the importance of sea surface temperature in controlling hurricane maximum intensity, and suggest an increase of 2-3 percent in hurricane strength per 1 Celsius degree increase in sea surface temperature under favorable conditions."
However directly connecting individual storms to the increasing sea surface temperatures related to climate change is still a difficult proposition. This is because "on top of the day-to-day intensity fluctuations due to local environmental conditions, hurricanes may also possess chaotic behaviors that cause their intensity to highly vary."
Read this article at CBS News: https://www.cbsnews.com/news/does-climate-change-affect-hurricanes/

increased hurricane frequency to increasing SST
One of the reasons for why it is so difficult to predict a change in hurricane frequency is due to intrinsic biases and assumptions built into the climate models being utilized.
While the 2012 Intergovernmental Panel on Climate Change reports that tropical hurricanes are likely to decrease in frequency with increasing temperatures, the storms that do form are likely to see increased winds and rainfall.
This article from Climate Central in 2013 details one study by MIT researcher Kerry Emanuel which found that tropical cyclones are likely to become both stronger and more frequent in the years to come, which is contrary to previous findings.

After the lamentable breach in the former international relations existing among men of science, it is with joy and gratefulness that I accept this opportunity of communication with English astronomers and physicists.
Einstein's letter was originally published in the 28 November 1919 issue of The Times, a British daily national newspaper.
During the war, Einstein lived and worked in Berlin, Germany. Communication between England and Germany seems to have been limited during the war, even among scientists in those countries. Because science is a collaborative endeavor that spans countries and cultures, Einstein understandably appreciates the renewed communication between these two important countries.

It was in accordance with the high and proud tradition of English science that English scientific men should have given their time and labor, and that English institutions should have provided the material means, to test a theory that had been completed and published in the country of their enemies in the midst of war.
Einstein published his equations that describe gravity with respect to space and time in 1915 —right in the middle of World War I (1914-1918).
Despite poor political relations during this period, two Englishmen published experimental evidence that supported Einstein's theory. Einstein commended the English scientists and institutions for prioritizing scientific pursuits over politics.

By preying on seabirds, foxes reduced nutrient transport from ocean to land, affecting soil fertility and transforming grasslands to dwarf shrub/forb-dominated ecosystems.
The effects of foxes on the Aleutian islands are both direct and indirect in nature. The presence of foxes directly affects the seabirds by decreasing their population due to them being easy prey. Indirectly the islands plant composition is affected by the reduced populations of birds distributing fewer nutrients needed by the vegetation. The U.S. Fish and Wildlife Service has been reducing fox populations in order to restore the seabirds and have the islands support more plant life.

role of the ocean as being critical to understanding the variability of Earth's climate system.
"The Ocean is essential to life on Earth. Most of Earth's water is stored in the ocean. Although 40 percent of Earth's population lives within, or near coastal regions- the ocean impacts people everywhere. Without the ocean, our planet would be uninhabitable."

Modeling studies are required even to be able to attempt such a partition.
"Underneath all the complexity of a big climate model lies a simple bedrock fact: In the long run, the Earth must balance its energy budget. However much incoming solar radiation the planet absorbs, the same amount must eventually be radiated back into space. The planet warms or cools as needed to satisfy this rule."

Bumble bee mutualism
With new research on the effects of climate change on bumble bee pollination and the decline in pollinators, new man-made developments have risen. We can see the start to a new possible era of man-made pollinators. This could help the declining rate of pollinators but can drastically affect the coevolution of flowers and their pollinators.

This article by Hungate et. al applies its findings to the Conservation Reserve Program, attempting to estimate species richness of CRP. This article ( D. L. Carter, J. M. Blair, Recovery of native plant community characteristics on a chronosequence of restored prairies seeded into pastures in West-Central Iowa. Restor. Ecol. 20, 170–179 (2012). ) is cited, yet this cited paper specifically does not use CRP grasslands, suggesting an error on the part of Hungate et al.

Valuation of the estimated annual marginal changes in carbon storage as species richness increases was then estimated using the social costs of carbon
The economic value of grassland species for carbon storage is one of the first papers to monetarily quantify the gain or loss of a species from an ecosystem. Even slight additions (as little as one additional species) to the current U.S. Department of Agriculture's Conservation Reserve program could save hundreds of millions of dollars.

The impact of dietary sugars on oocyte Wolbachia titer is currently best explained through nutritional impacts on the host.
Female mosquitoes with sugar-fed diets survive longer than those without sugar-diets. Wolbachia titer size is affected by levels of sugar in the host's diet, which may show correlation between mosquito life expectancy and Wolbachia titer size from dietary sugars.

ZIKV is highly neurotropic and interferes specifically with fetal brain development, causing microcephaly, cortical malformations, and intracranial calcifications (7–10). We hypothesized that the single-stranded RNA flavivirus ZIKV may hijack RNA-binding factors present in the developing central nervous system (11). Host RNA-binding proteins are known to interact with untranslated regions (UTRs) to regulate replication, translation, and stabilization of viral genomes
Zika is known to have the ability to reinfect other humans because it is known to be found in the blood and continuously be transmitted by mosquitos. Zika virus utilizes host cellular machinery to replicate, and symptoms may emerge a few days to a week after infection.

A recent survey of recreational SCUBA divers in the Caribbean found that shark sightings are quite rare, except for some places that have shark conservation regulations or large marine reserves in place
According to the NOAA, the removal of shark fins is prohibited by federal law. This practice, coined "shark finning" has been abolished in the United States since 2000. For further information on government involvement in shark regulations and management, visit this NOAA page
Furthermore, the Caribbean Reef and Caribbean Sharpnose sharks are both prohibited from being harvested, as this Florida Fish and Wildlife Conservation Commission site shows shows. -Sindy

Sharks are currently experiencing intense fishing pressure worldwide, largely due to the Asian shark fin trade
The Asian shark fin trade has been detrimental to the shark population and according to the The National, a Marine Conservation group called Sea Sheppard Global is campaigning for shark conservation and cleaner oceans in the Middle East. Finning is one of if not the greatest threat to sharks. It entails the process of cutting of the sharks fin and leaving its body in the sea to bleed to death or be eaten by other fish. The point of finning is to make shark fin soup which is an Asian delicacy or to sell for price ranged between $10,000-$20,00. In 2016, congress passed the Shark Fin Trade Elimination act which banned the shark fin trade. Despite this, Shark fins are still being trafficked to the country. https://www.thenational.ae/uae/environment/marine-conservation-group-launches-in-middle-east-1.673006 -Sindy

cytoplasmic binding partners
https://www.sciencedaily.com/releases/2016/08/160804102311.htm
It is traditionally thought that proteins that are involved in the regulation of translation and transcription are in two different categories. However, researchers at Umea University in Sweden and Inserm in France have now discovered that there is a gray area when discussing regulation of genetic expression at different levels.
The researchers have discovered that some proteins, specifically p53, have the ability to control the expression of the MDMX gene at both transcription and translation. By mutating the region of the p53 gene that encodes the DNA binding domain of the protein (making the translated p53 protein unable to bind to DNA) researchers observed that the control MDMX gene expression was still being regulated by p53 during translation.
From this discovery we can draw the conclusion that protein regulation of genetic expression is even more complex than previously thought.

Puromycin is an inhibitor of protein synthesis. This article explains why the researchers were unable to see the KDM5B protein after the addition of puromycin. Puromycin causes a premature release of protein chains. The ribosome falls off of the mRNA before translation is complete. The ribosome dissociates into its subunits.

This poll explored global regional differences in the perception of the threat posed by climate change. Around the world, around 51% of those polled said that climate change is already harming people. Globally, the poll found that a majority of people think their countries should limit greenhouse gas emissions and that the world needs an international agreement to curb emissions.
Within the United States, Canada, Australia, and Germany, large differences in concern about climate change were found between followers of right-of-center parties, who were less concerned, and followers of left-of-center parties, who were more concerned.

Individuals whose actions are informed by a deeper understanding of how the planet really works
Ecoliteracy is understanding how healthy natural systems operate. This includes principles such as:
- All life is interconnected
- There are limits to how quickly natural resources such as fish and trees regenerate
- Changes humans make affect everything else in the ecological system
Ecologically-inspired principles such as these are critical for creative and appropriate changes to the transportation, food, and energy systems that humans design.

This is a relatively new idea, set forth in the late 1980s. So, even if middle school and high school science teachers took ecology courses in college, many have had no formal training about climate science. This makes it very challenging to teach students about climate change.

set machine defaults to efficiency modes
You may be familiar with sleep mode on your computer, or you might have seen a printer that defaults to double-sided printing. This type of resource- and energy-saving default mode helps people behave more sustainably without taking any action at all.
Hotels are now installing energy-saving devices that turn off lights and turn down heat when guests leave the room. The guests do not have to do anything to save energy—the devices to it for them.

Individuals—informal and formal leaders, decision makers, workers, volunteers, and members—are the underlying force
Change begins with an individual. But that is not enough. An individual needs to step forth with an idea for change and then others need to be the first followers. Social science researchers have developed a model for how new ideas turn into a social movement. It begins with an innovator, early adopters see the innovation and try it, then others see the early adopters and copy what they do. Eventually the remaining people join because they don't want to miss out.

We all have a need to feel competent. Trying something new can be discouraging when we haven't seen others doing it, we haven't learned how to do it in school, or we think others won't approve of the activity. It is common for people to resist trying these new behaviors until they develop the appropriate skills and feel socially comfortable.

Neighborhoods are an example of complex systems that help us live, travel, work, and play. Suburbs built after World War II tend to be designed around the use of cars. For instance, building homes that are far away from commercial districts containing offices, retail, and entertainment encourages more driving. These systems also include large, single-family homes which use more energy to heat and cool.

Distal blastemal cells are converted to more proximal cells by exposure to retinoic acid or other retinoids
Retinoic acid (a major component of vitamin A) and derived compounds are often used to treat acne. Many of these drugs, however, are known to cause major birth defects at the dosages effective for treating acne. The drug isotretnoin (brand name Accutane®) is in particular known to cause severe birth defects.
As a result, there is heavy regulation of this drug including mandatory birth control. This, unfortunately, was not always the case and resulted in many children born with birth defects. See this article in The New York Times for more:
http://www.nytimes.com/1984/10/11/us/acne-drug-accutane-linked-to-severe-birth-deformities.html
Although development is not regeneration, retinoic acid's role in causing defects in both these processes does highlight shared similarities. Retinoic acid does not disrupt every biology process, you need vitamin A to live of course!
Because retinoic acid is capable of disrupting both these processes this does suggest some link between the two.

homozygosity mapping
To improve the quality of results, the authors chose consanguineous families (families that share a very recent ancestor), because of their high risk of having autistic children.
Researchers at Johns Hopkins University reasoned that families with multiple females with autism must have special genetic variants for autism that can be more easily identified than when comparing other groups.

heterogeneous disorders
Autism is a "heterogeneous" disorder because not all autistic people have the same genetic anomalies. Autism is difficult to characterize not only because there are many different genes that can cause it, but also because autism sometimes results when several otherwise benign mutations come together in the genome of an individual.

Early attempts to understand electricity made use of electric eels
Both bio-fuel cells and high voltage liquid electrolyte microbatteries have been inspired by the Electric Eel.
More recently a "protocell" was designed by Dr. David LaVan at the National Institute of Standards and Technology in Maryland in which the electric charge difference between two cells and the flow of ions through the shared membrane was used to generate electricity much like that generated by the cells of electric Eels.

transfection of mammalian Cos 7 cells
Transfection of not cell cultures, but whole organisms is now a possible feat. Often this is done using a virus-based transfection system.
The virus contains the gene you want expressed in the organism and that virus then goes and infects cells. These viruses can be specifically designed to target certain organs like the liver or brain, so that only the organ you want has that DNA and is expressing that protein.
This process is becoming so safe and efficient that it is now being used in extreme circumstances on humans. If a person suffers from a disease caused by a mutation in a gene, a working version of it could theoretically be inserted into their cells using viruses.
Often this concept is lumped together under the broad term "genetic engineering," but is more appropriately termed "gene therapy."
Although this field has been plagued with many past disasters, new advances and better understanding of viral biology is making this a viable treatment for many diseases. The field of gene therapy is still recovering after the death of Jesse Gelsinger, among others.
