Evidence of resistance to a “last-resort” drug for antibiotic-resistant bacteria is discovered among farm animals for the first time.

the-scientist.com - by Ben Andrew Henry - December 7, 2016

Modern agriculture relies on antibiotics to shield livestock from disease, but widespread over-use of antibiotics has raised concerns over creating highly resistant “superbugs.” Researchers announced this week (December 5) that bacteria carrying a rare, dangerous gene for antibiotic resistance have been found in agricultural animals for the first time.

In a study published in Antimicrobial Agents and Chemotherapy, researchers took swabs and fecal samples from a pig farm and discovered bacteria resistant to carbapenems, an important class of antibiotics.

Zika in Fetal Brain Tissue Responds to a Popular Antibiotic

Working in the lab, UC San Francisco researchers have identified fetal brain tissue cells that are targeted by the Zika virus and determined that azithromycin, a common antibiotic regarded as safe for use during pregnancy, can prevent the virus from infecting these cells . . .

 . . . In the new study, published online Nov. 29, 2016, in the Proceedings of the National Academy of Sciences (PNAS), the UCSF researchers determined that the Zika virus preferentially infects brain cells with an abundance of a protein called AXL, which spans the outer cell membrane of several cell types and serves as a gateway for the invading virus . . .

Texas Reports First Case of Zika Spread by Local Mosquitoes

reuters.com - by Julie Steenhuysen - November 28, 2016

Texas health officials on Monday reported the state's first case of Zika likely spread by local mosquitoes, making Texas the second state within the continental United States to report local transmission of the virus that has been linked to birth defects.

The case involved a woman living in Cameron County near the Mexico border who is not pregnant, the Texas Department of State Health Services said.

Pregnancy is the biggest concern with Zika because the virus can cause severe, life-long birth defects, including microcephaly, in which a child is born with an abnormally small head, a sign its brain has stopped growing normally . . .

 . . . In adults, Zika infections have also been linked to a rare neurological syndrome known as Guillain-Barre, as well as other neurological disorders.

Unless the world stops burning fossil fuels that are fuelling global warming, irreversible changes in the Arctic could have disastrous effects for the people that live there and for the rest of the planet, researchers warned on Friday.

The Arctic's ecosystems are fundamentally threatened by climate change and other human activities, such as oil and gas extraction, they said in a report for the Arctic Council, an inter-governmental forum working to protect the region's environment.

Microcephaly Found in Babies of Zika-Infected Mothers Months After Birth

It is the news that doctors and families in the heart of Zika territory had feared: Some babies not born with the unusually small heads that are the most severe hallmark of brain damage as a result of the virus have developed the condition, called microcephaly, as they have grown older.

The findings were reported in a study of 13 babies in Brazil that was published Tuesday in Morbidity and Mortality Weekly Report. At birth, none of the babies had heads small enough to receive a diagnosis of microcephaly, but months later, 11 of them did . . . 

 . . . The new study echoes another published this fall, in which three babies were found to have microcephaly later in their first year.

Climate Changing 'Too Fast' for Species

           

Tropical species are thought to be particularly vulnerable.  Thinkstock

CLICK HERE - STUDY - Rates of change in climatic niches in plant and animal populations are much slower than projected climate change

bbc.com - by Helen Briggs - November 23, 2016

Many species will not be able to adapt fast enough to survive climate change, say scientists.

A study of more than 50 plants and animals suggests their ability to adapt to changes in rainfall and temperature will be vastly outpaced by future climate change.

Amphibians, reptiles and plants are particularly vulnerable, according to US researchers.

And tropical species are at higher risk than those in temperate zones.

At The U.S.-Mexico Border, Haitians Arrive To A Harsh Reception

           

Haitian nationals at a Mexican government immigration office near the port of entry between Nogales, Sonora, Mexico, and Nogales, Ariz., wait day after day for appointments with U.S. immigration agents so they can enter. As a result of the Haitian influx and a continuing surge of Central Americans on the Texas-Mexico border, the U.S. government has run out of detention space.  John Burnett/NPR

npr.org - by John Burnett - November 23, 2016

Desperate Haitian immigrants have been massing along the U.S.-Mexico border for months seeking humanitarian relief. In the past year more than 5,000 have sought entry into the United States — a 500 percent increase over the previous year.

After the catastrophic 2010 earthquake in Haiti, thousands of citizens migrated to Brazil looking for work. But as Brazil has slipped into recession in recent years, many of them have hit the road again, heading north on a 6,000-mile journey to the U.S. border — by every means of conveyance . . .

 . . . The Homeland Security Department announced new rules in September. All Haitians who show up at the border without papers and who don't ask for asylum are now detained.

Polluted city air has now been identified as a possible means of transmission for resistant bacteria. Researchers have shown that air samples from Beijing contain DNA from genes that make bacteria resistant to the most powerful antibiotics we have.

Oil demand won't peak before 2040, despite Paris deal: IEA

reuters.com - November 16th 2016 - Amanda Cooper

The International Energy Agency expects global oil consumption to peak no sooner than 2040, leaving its long-term forecasts for supply and demand unchanged despite the 2015 Paris Climate Change Agreement entering into force.

The Paris accord to cut harmful emissions seeks to wean the world economy off fossil fuels in the second half of the century in an effort to limit the rise in average world temperatures to "well below" 2 degrees Celsius (3.6 Fahrenheit) above pre-industrial times.

But while demand for oil to power passenger cars, for example, may drop, other sectors may offset this fall.
