Fall bird migration is underway, and millions of birds are beginning to reach Philadelphia as they head south for the winter, newly hatched young embarking on their first migration. Bird Safe Philly is asking Lights Out Philly participants — and everyone — to turn off or block non-essential lights from midnight to 6:00 a.m. from August 15 to November 15 to protect migratory birds traveling along the Atlantic Flyway.

A Shaker of Science: Waxing Weather
Thursday, September 23, 2021, 5:30–6:30 p.m.

a shaker of science, virtual happy hour

From pumping us up for a possible snow day, to saving lives with early extreme weather warnings, the local weather is an integral part of our daily lives. Data is constantly being gathered and crunched to provide forecasts. But it’s not all satellites, radar and supercomputers. When it comes down to how the weather will affect your life, we rely on our local weatherman (or woman) to sort through the noise, double check the data, and deliver the forecast relevant to us.

At this month’s Shaker of Science, we are excited to have one of the best in the business, NBC10 First Alert Meteorologist Steve Sosna! Steve is taking us behind the scenes to show us how the NBC10 First Alert Weather team turns weather data into the weather reports we rely on each and every day. Oh, and did we mention copters? Yeah, we’ll talk about helicopters.

Steve Sosna, NBC10 First Alert Weather Team Meteorologist

Steve Sosna is a meteorologist for NBC10’s First Alert Weather team. You can watch Steve's forecasts weekend evenings on NBC10 and listen to his forecasts on KYW Newsradio. Steve is an active member of the American Meteorological Society (AMS) and has earned the prestigious AMS Certified Broadcast Meteorologist (CBM) seal of approval. Steve is also the recipient of a National Emmy for his award-winning work with StormRanger, NBCUniversal's state-of-the-art, mobile, dual pol X-band Doppler Radar.

Gideon Mendel: Drowning World is a unique photographic exploration of flooding, a stark portrayal of the human condition within the context of overwhelming climate events around the world. The exhibition features 37 photographs, two found-object displays and a video by leading contemporary photographer Gideon Mendel, a native of Johannesburg, South Africa. Mendel began photographing major floods in 2007 when one in the United Kingdom and another in India occurred within two weeks of each other. Their proximity struck him as a shared vulnerability that seemed to unite people. Drowning World includes color images of some of the poorest and wealthiest communities on the planet, all exposed to the floodwater that envelops them. In this moment the floods are a leveling factor, and people are brought together in visual solidarity.

Lights Out Philadelphia

Bird Safe Philly has announced that Philadelphia is joining the national Lights Out initiative. This voluntary program involves turning off or blocking as many external and internal building lights as possible at night during migration seasons when birds are passing through the city by the millions.

The first season of Lights Out Philly launches April 1, at the start of peak spring migration and runs through May 31, when most winged migrants will have passed through Philadelphia. 

During the spring and fall migration periods, property managers and their tenants will be asked to voluntarily switch off unnecessary lights, especially in a building’s upper levels, lobby and atrium, and turn off or dim external lighting. 

Lights Out Philly is the result of a collaborative effort led by the Academy of Natural Sciences of Drexel University, Delaware Valley Ornithological Club, National Audubon Society-Mid-Atlantic Region, and two local Audubon Society chapters (Valley Forge and Wyncote).  
 
The Bird Safe Philly initiative is endorsed by the City of Philadelphia’s Office of Sustainability, the Building Owners and Managers Association Philadelphia, and the Building Industry Association of Philadelphia. 

These have pledged their support as early adopters: 

  • Comcast Technology Center and Comcast Center, the two tallest buildings in the city 
  • Brandywine Realty Trust, the city’s largest landlord 
  • A dozen other building operators 

Philly joins 33 other cities in nation in signing on to Lights Out.

Reading the Leaves

pressed plant leaf on white background 

The veins in a leaf do more than store water for the plant; even plant leaves preserved as fossils. They can reveal what environmental conditions were like when and where the plant was growing.

Leaf veins are a passion for Zack Quirk, a National Science Foundation fellow and University of Michigan paleobotany PhD candidate, who’s been using the Academy’s Botany Collection to measure the length of veins in plants. He chose the Academy herbarium because of it wide range of specimens collected from around the world. To collect these plants on his own would be prohibitively expensive and time-consuming.

The Name’s Bondi, Synodus bondi

syondus bondi fish specimen

Scientists at the Academy have a long history of contributing specimens not only to the collections of their primary field of study, but also to other collections throughout the museum. For example, Edward Drinker Cope is best known for his contributions to paleontology, but he was also an early driving force behind the creation of the Academy’s Ichthyology and Herpetology collections.

It remains common today for our researchers to bring back specimens from collecting expeditions for their colleagues in other departments. They may collect some mollusks while gathering fish or pick up some interesting specimens for sale in a market. Every so often their efforts may be rewarded with a new species named in their honor.

This is what happened in 1939 when Ichthyology Curator Henry Weed Fowler described a new species of lizardfish from Jamaica and named it Synodus bondi. The specimens used in the description were collected by an ornithologist from the Academy by the name of James Bond, a name made famous by Ian Flemming when he borrowed the moniker for his spy novels.

Is COVID-19 Affecting Our Water?

drain

The COVID-19 pandemic has resulted in many lifestyle changes around the globe, namely —  people are staying at home.

The onset of this extreme, sudden and nearly universal social isolation has prompted our Biogeochemistry Section scientists to ponder what kinds of changes in water quality they might see due to COVID-19.

With the large-scale shift to people working at home and sheltering in place, there will likely be an increase in suburban wastewater effluent. Effluent is an outflowing of water or gas to a natural body of water, from a structure such as a wastewater treatment plant, sewer pipe or industrial outfall.

Will this cause changes in water quality that we will be able to detect over time, as social distancing measures continue to be in effect?

Recycling 101

recycling bins on street

In January 2019, we learned that over 50% of Philadelphia’s recycling was being sent straight to an incinerator in Chester. The problem was part of a larger issue with recycling nationwide — that the market for purchasing recycled goods, with China being the primary buyer, had shifted greatly. In 2018, China decided to no longer accept recycled materials that didn’t meet new stringent rules around contamination and mixed materials. Soon, recycling, which had actually been profitable for Philadelphia, became an expense for the city.

One of the main reasons that much of Philadelphia’s and the United States’ recycling is so expensive to sell is that it is deeply contaminated. You can help address this problem by knowing what you can recycle and how best to clean your recycling. On the Academy Blog, find out the answers to these common questions about recycling in Philly:

  • How clean should my recycling be?
  • What can and can’t you recycle curbside?
  • What can you recycle at a special facility?
  • How can you reduce the amount of recycling you create?
  • What does yard waste and composting have to do with creating less waste?
  • What resources can help me recycle properly in the Philadelphia suburbs?

A Real Shocking Discovery

eel

Academy Ichthyologist Mark Sabaj is one of the co-authors on the descriptions of two new species of electric eel.  

Scientists have discovered a new species of eel that can discharge up to 860 volts of electricity – significantly more than the 650 volts previously recorded by what had been believed to be the only type of eel in existence… until now.

Mark Sabaj, PhD, interim curator of fishes at the Academy of Natural Sciences of Drexel University is well-versed in techniques for catching electric eels both with and without getting shocked. He contributed to a large study of electric eels as a member of a multinational team led by Carlos David de Santana, an ichthyologist at the National Museum of Natural History in Washington, D.C. Sabaj is a co-author on the descriptions of two new species, Electrophorus voltai and Electrophorus varii, published in Nature Communications.

Mussel Survey

In late September, Academy staff scientists and collaborators conducted a mussel survey on the Schuylkill River upstream from Boathouse Row. Their goal was to document the presence or absence of mussels and, in particular, whether there were any Tidewater Mucket (Leptodea ochracea) in this stretch of the river. This survey was the last in a series that was conducted throughout the lower Delaware River watershed.

Four Ways to Cut Your Carbon

scientists on boat

Looking to reduce your personal carbon emissions? There are some big steps you can take. For example, if you need to travel a long distance, you can choose rail or even sailboat — to follow in Greta Thunberg’s wake — rather than flying. The 16-year-old Swedish climate activist last week completed a transatlantic journey by racing yacht to attend the United Nations summit meeting on global warming this month. Few of us fly every day, and fewer sail. So how can we do our part to reduce CO2 emissions (which contribute to harmful greenhouse gases largely blamed for driving global warming) in our daily life?

Time Outdoors: It’s Healthy

academy scientists in creek

Doctors and psychologists have long recognized that spending time in nature leads to a healthier well-being, and a growing field of research aims to better understand and quantify the benefits of spending time in nature. Time spent outdoors is related to lower stress levels, decreased blood pressure, and a reduced risk of chronic diseases such as asthma, allergies, diabetes and cardiovascular disease.

So, if the prescription is to spend more time in nature, what’s the dosage? A recent The New York Times article highlights some new findings, namely that researchers have zeroed in on the ideal amount of outdoor time for reaping nature’s maximum health benefits: 120 minutes per week. Two hours in a week doesn’t seem like a lot of time, but it can sometimes be difficult to fit that time into our already hectic schedules.

Click here for some easy suggestions for adding 120 minutes of outdoor time to your week. 


Where Does Your Water Come From?

scientists on boat

The Wissahickon Creek watershed is 64 square miles and covers portions of Montgomery and Philadelphia counties in Pennsylvania. The Wissahickon is a small but important part of a larger system. It is a tributary of the Schuylkill River, which in turn is the largest tributary of the Delaware River. The whole Delaware River Basin covers 13,500 square miles and provides water for more than 15 million people, including half of New York City’s potable water supply. Do you know the source of your drinking water?

Keeping Tabs on the Environment

scientists in stream

Summertime means the height of field work season for many Academy scientists. They can be found up and down the Delaware River watershed measuring fish, collecting algae samples, measuring sea level rise due to climate change, testing water for the presence of harmful chemicals and more. Wading in cool streams, hiking bucolic trails, walking through wetlands, and boating to find the fish are all involved. But so are smacking mosquitoes, sweating in waders, battling sun burn, and lugging equipment in heat and humidity. But all in all our scientists agree: it beats sitting in the office!
