Just a week after Amazon fired a worker who led a walkout, workers at the same Staten Island warehouse walked off the job again Monday to protest unsafe working conditions as online orders soar during the pandemic. We get an update from Angeles Solis, lead organizer at Make the Road New York, which helped organize the strike. Solis helps lead the group’s Beyond Amazon coalition in New York City. If Amazon doesn’t do more to protect workers, “they are not only profiting from this pandemic, but they’re helping to perpetuate it,” Solis says. We also talk about mutual aid organizing among immigrant and low-income communities, and Make the Road’s COVID-19 Emergency Response Fund.

Scientists develop new way to identify the sex of sea turtle hatchlings
Study provides crucial step to assess climate change impacts on imperiled turtle species
April 7, 2020
Summary: A new minimally invasive technique greatly enhances the ability to measure neonate turtle sex ratios. This is the first time that differences in sex-specific protein expression patterns have been identified in blood samples of hatchlings with temperature-dependent sex determination. The technique is a crucial step in assessing the impact of climate change on imperiled turtle species and will enable more accurate estimates of hatchling sex ratios at a population level and on a global scale.
Unlike humans, sea turtles and other reptiles like crocodiles do not have sex chromosomes. Their sex is defined during development by the incubation environment. In sea turtles, sex is determined by the nest’s temperature: warmer temperatures produce females and cooler temperatures produce males. It is especially challenging to identify the sex of hatchling sea turtles because they lack external sexual organs and heteromorphic sex chromosomes — no X or Y. To date, there are a limited number of ways to reliably identify sex in turtle hatchlings. With the rapid increase of global temperatures, there is an urgent need to clearly assess sex ratios in these imperiled animals.
Researchers from Florida Atlantic University’s Charles E. Schmidt College of Science have developed a first-of-its-kind technique that is minimally invasive and greatly enhances the ability to measure neonate turtle sex ratios at population levels across nesting sites worldwide. They used this technique to identify sex in neonates of two turtle species: a freshwater turtle (Trachemys scripta) and a marine turtle (Caretta caretta) using analysis of small blood samples. This is the first time that differences in sex-specific protein expression patterns have been identified in blood samples of hatchlings with temperature-dependent sex determination. This research is a crucial step in assessing the impact of climate change on imperiled turtle species.
For the study, published in Scientific Reports, researchers used an immunoassay approach to test samples for the presence of several proteins known to play an important role in sex differentiation. Results of the study showed that anti-müllerian hormone (AMH) can reliably be detected in blood samples from neonate male turtles but not females and can be used as a sex-specific marker.
Researchers verified the sex of the turtles using histology or laparoscopy, which revealed that the new method they developed is 100 percent reliable for identifying sex in both the freshwater turtle and the loggerhead sea turtle in 1- to 2-day-old hatchlings and was 90 percent reliable for identifying sex in 83- to 177-day-old (120 — 160g) loggerhead juveniles.
“The challenges inherent in the methods that are currently being used to identify the sex of neonate turtles with temperature-dependent sex determination is what inspired us to look for an alternative approach,” said Jeanette Wyneken, Ph.D., co-author and a professor of biological sciences in FAU’s Charles E. Schmidt College of Science. “Results from our study provide the field of reptile conservation, and in particular, turtle conservation and management, with a valuable new tool that can be used to accurately assess the sex ratios of hatchlings.”
In comparison to the current molecular methods for sex identification in turtles with temperature-dependent sex differentiation, the approach developed by FAU researchers using blood samples via western blot analysis is quick, minimally invasive (requires a very small volume of blood), and the hatchling turtle can then be released immediately.
“Information from our study should enable other scientists and managers to precisely monitor changes in sex ratios that might arise as a consequence of changes in temperature over time,” said Boris Tezak, Ph.D., senior author who conducted the research as part of his Ph.D. studies at FAU and is now a post-doctoral researcher at Duke University Medical Center. “It also will help them to estimate how climate change will affect future generations of hatchlings, and allow for expedited evaluation of management strategies used to help recover imperiled sea turtles and other reptile species with temperature-dependent sex determination.”
Identifying natural turtle hatchling sex ratios at nesting sites is challenging for a variety of reasons, spanning morphological limitations to ethical issues to a lack of understanding of the mechanisms that actually direct embryonic sexual differentiation. Generally, turtles are characterized by being long-lived and late-maturing, so they are not sexually dimorphic until approaching sexual maturity — marine turtle species often take more than 25 years to become sexually mature.
“Due to the difficulties associated with readily identifying hatchling sex, most large-scale studies investigating turtle hatchling sex ratios rely on proxies to infer sex ratios indirectly such as nest temperatures, air temperatures or nest incubation durations,” said Itzel Sifuentes-Romero, Ph.D., co-author, a post-doctoral fellow of biological sciences in FAU’s Charles E. Schmidt College of Science, and a post-doctoral fellow of FAU’s Brain Institute (I-Brain). “However, these alternatives often fail to match the primary sex ratios from natural turtle nests or rookeries. We believe that the novel technique we have developed will allow for more accurate estimates of hatchling sex ratios at a population level and on a global scale.”

Coronavirus social crisis: ‘I can’t live on universal credit’
The coronavirus outbreak is not just a public health crisis, it’s a social crisis. Owen Jones speaks to three self-employed people who have lost their livelihoods almost overnight and have turned to the universal credit system. How are they coping during the lockdown? And can they survive on government support?
Bogus self-employment epidemic collides with the coronavirus epidemic. MARK HARVEY of the Institute of Employment Rights argues that Britain has walked into a perfect storm due to employers forcing workers to register as self-employed — with no responsibility toward them in times like the present crisis.

‘Gross negligence’ from tax bosses putting workers’ lives in danger
Union secure closure of one office after death but warns mandarins are blocking vital safety measures
PRESSURE to close all government tax offices where there have been cases of coronavirus mounted today after one was forced to shut following the death of a civil servant who worked there.
The closure of Trinity Bridge House in Salford, Greater Manchester, came following intense pressure on HM Revenue & Customs chiefs from the Public & Commercial Services union (PCS), which represents more than 180,000 Civil Service workers.
The coronavirus death in Salford was followed by the reported infection of another worker who had been instructed by bosses to continue working in the office.

DOCTORS condemned the provision of protective wear as “useless” today, warning that it was putting their lives at risk.
More than two-thirds of doctors (69 per cent) said they do not feel protected from Covid-19 infection, according to a British Medical Association (BMA) poll.
Some have also said they feel forced to work in high-risk areas without the right kit.

Coronavirus infecting postal workers
Some 4,420 postal workers are under quarantine as a result of possible exposure to coronavirus, according to the United States Postal Service and the National Association of Letter Carriers (NALC). Already some 294 have tested positive for COVID-19 with 8 deaths. Postal workers nationwide are reporting a lack of protective equipment and cleaning supplies for its 630,000 workforce.
In an April 3 statement, Fredric Rolando, president of the NALC, said to union members, “USPS has committed to provide daily supplies necessary for postal employees to clean frequently touched items in the office as well as provide necessary supplies for letter carriers to use to clean steering wheels and other frequently touched surfaces in postal vehicles. … You should have sufficient hand sanitizer to keep your hands clean all day as you touch the many surfaces on your route.”
But letter carriers deny this to be the case and in another statement, Rolando admitted, “In some places, all of these things are being done. However, in too many places they are not.”
Irvine, California nurses protest lack of protective equipment
Over 50 nurses at the UCI Medical Center in Irvine, California staged a protest April 3 over management’s refusal to provide Personal Protective Equipment (PPE) and disciplinary measures against nurses who wear masks in areas where they are restricted. Nurses marched from the hospital to UCI Health administration facility to deliver a petition but were denied entry to deliver it.
“We’re here to fight,” Maria Louviaux, a UCI Health nurse, told CBSLA news. “Even just to wear our surgical mask throughout our shift, we have to fight for that, and unless nurses meet certain criteria, we aren’t allowed to wear masks. In fact, we are intimidated and on the verge of bullying at times by managers and directors.”
Nurses claim the hospital has N95 respirator masks, but they are kept locked up. According to a management statement, the hospital is “keeping PPE secure so they are available for health care workers who need it,” essentially barring nurses from their use.
