Study Notes
Crab Spider Camouflage in Yuan Province Rainforest
- Chinese scientists observed a male and female crab spider mimicking a flower in a Yuan Province rainforest.
- The male resembled the flower's pistils and stamens, while the female resembled the petals.
- The successful camouflage initially perceived them as a single entity.
- Female crab spiders commonly camouflage themselves with flowers, often adjusting their color to match.
- This male-female cooperation is the first documented instance of "cooperation mimicry" in any species.
- This adaptation requires both participants for the deception to work.
- Researchers believe this cooperative behavior improves survival and hunting chances.
- This behavior was observed on March 1, 2024.
New Ichthyosaur Species Discovered
- A new, massive ichthyosaur species, Ichthyotitan severnensis, was discovered.
- Discovered by a father-daughter team, Justin Reynolds and Ruby Reynolds, during fossil hunting at Blue Anchor Beach, Somerset, England.
- Initially found a small oval fossil, followed by a larger bone fragment.
- Dr. Dean Lomax confirmed the fossils belonged to an ichthyosaur.
- Extensive search for additional fossil pieces resulted in reconstructing the lower jaw.
- An estimated 80 feet long (equivalent to two buses parked end to end), making it one of the largest marine animals ever.
- Discovery helped by similar ichthyosaur's remains from 2016.
- Ruby Reynolds and Justin Reynolds are co-authors of a study published in PLOS One (April 17, 2024).
- Ruby, now 15, continues to advocate for youth involvement in science.
Periodical Cicada Emergence
- Sixteen US states are experiencing a rare simultaneous emergence of two cicada broods.
- Brood XIX (13-year cycle) and Brood XIII (17-year cycle) are overlapping.
- This last occurred 221 years ago and will not happen again until 2245.
- Cicadas emerge to reproduce and die subsequently.
- Primarily black, shrimp-sized bugs with red, beady eyes.
- Cicadas spend most of their lives underground, feeding on tree roots.
- Emergence expected to peak for two to three weeks, starting mid-May.
- Highest overlap projected for Illinois and Iowa.
- Cicadas are harmless to humans.
- Produce a loud, high-pitched drone (approaching 90 decibels).
- They cause damage to young trees by laying eggs on slender twigs or vines, potentially stunting or killing young fruit or nursery trees.
- Covering trees with nets is recommended to prevent damage.
- Cicadas die soon after laying eggs, providing food and nitrogen to trees.
- Eggs hatch within 4-6 weeks, restarting the 13 or 17-year cycle underground.
- Cicada emergence cycles are prime numbers, to avoid predators with shorter lifespans.
2024 Summer Olympics in Paris
- The 2024 Summer Olympics will include four new sports: breaking, surfing, skateboarding, and sport climbing.
Breaking (Breaking Dance)
- Breaking, an urban dance style, will make its Olympic debut in Paris.
- Two events (one each for men and women).
- Sixteen athletes per event will perform judged routines on style, flair, and mandatory moves.
Surfing
- Surfing, debuting in Tokyo 2020, will return in Paris.
- Tahiti will host the competitions from July 27 to August 5, 2024.
- Competitors judged on maneuver variety, speed and flow, and difficulty of tricks.
Skateboarding
- Skateboarding is returning to the Olympics after Tokyo.
- Two disciplines: park and street.
- Park: three 45-second runs judged on the best, navigating obstacles.
- Street: five tricks in two 45-second runs on a flat urban street with obstacles.
- Evaluated on board control, trick diversity, and style.
Sport Climbing
- Sport Climbing returns for its second Olympics in Paris.
- Three events: bouldering, speed climbing, and lead climbing.
- Bouldering: unroped climbs up 4.5 m walls, highest score in fewest attempts.
- Speed Climbing: competitors climb the wall rapidly.
- Lead Climbing: climb a 15 m wall without route knowledge within a six-minute time limit.
- Paris Olympics combine bouldering and lead climbing scores, and speed climbing will have its own medal.
Sumatran Orangutan Wound Treatment
- A Sumatran orangutan, named Rakus, treated a cheek wound with a medicinal plant, liana.
- 35-year-old male orangutan in Gunung Leuser National Park, northern Sumatra, Indonesia.
- Researchers noticed the wound on June 22, 2022, likely from a fight.
- Three days later, Rakus was observed chewing on liana leaves and applying the juice to the wound, preventing flies.
- Wound fully healed in five days.
- This is the first known instance of a wild animal actively treating a wound with a medicinal plant.
- The study, published in Scientific Reports on May 2, 2024, notes Rakus' excellent patience, returning to the plant and resting more to aid healing.
- Sumatran orangutans, critically endangered at about 14,600, are only found in northern Sumatra.
- Rainforest conversion to palm oil plantations and hunting are major threats.
- Females give birth to one infant every eight to nine years, making populations vulnerable to hunting.
Tornadoes
- Tornadoes can strike the United States year-round, peaking from March to July.
- "Tornado Alley" (Texas, Oklahoma, Kansas, Nebraska, South Dakota, Indiana, Missouri, Iowa, and Ohio) is most susceptible.
- April activity averages around 182 tornadoes, but saw over 300 in 2024.
- A significant outbreak occurred from April 25-28.
- 30 tornadoes in Oklahoma, at least two dozen in Iowa, 20 in Texas, 16 in Missouri, 15 in Kansas, and 13 in Nebraska.
- Marietta, Oklahoma, was hit by an EF-4 tornado on April 27, causing one death and significant damage, including to a hospital and nursing home.
- Minden, Iowa, experienced a powerful storm that destroyed 48 homes and damaged over 300 structures on April 26.
- May 2024 saw at least 133 reported tornadoes, concentrated around Oklahoma, Michigan, Tennessee, and even Florida (Tallahassee, struck by three tornadoes on May 10).
- Thousands remained without power in Florida after these events.
- While 2024 numbers are historically high, previous records remain far higher (1287 in 2011 by May 7).
- A tornado is a powerful rotating column of air starting at a thunderstorm cloud's base.
- Supercells, severe rotating storms, are necessary for tornado formation (cold, dry polar air meeting warm, moist tropical air).
- As warm air rises, winds create rotation, and a low-pressure area sucks in more air.
- Tornadoes can linger for hours, unlike ordinary thunderstorms (30-60 minutes).
- The U.S. experiences approximately 1,200 tornadoes annually.
- Tornado Alley's geography (Rocky Mountains dry air, Gulf of Mexico humid air, Arctic air) creates optimal storm conditions.
NASA's X-59 QueSST Aircraft
- NASA's X-59 aircraft aims to revolutionize supersonic travel.
- Designed for supersonic flight without sonic booms.
- Part of the US Space Agency's Quiet SuperSonic Technology (QueSST) mission.
- Supersonic speed exceeds the speed of sound, approximately 768 mph (1,236 km/h).
- Sonic booms, disruptive noises, from supersonic flight hindered the Concorde.
- The X-59's unique design breaks up shock waves, reducing noise.
- The cockpit's forward-facing window is removed for advanced camera-based flight.
- The engine is positioned on top for noise redirection.
- Testing is planned for late 2024 in California, with community feedback in select US cities.
- This data could persuade airline officials to permit supersonic flights over land, potentially leading to commercial supersonic aircraft by 2030.
Rising Sea Levels and Floating Cities
- Rising sea levels, fueled by global warming, are escalating at an alarming rate, putting coastal communities worldwide at risk.
- Experts predict nearly 300 million people living in coastal areas will face annual flooding by 2050.
- Japan's N-Ark plans a floating city, Dogen City, to combat climate change.
- Dogen City will be roughly 1 mile (1.58 km) in diameter and 2.5 miles (4 km) in circumference.
- Its circular shape protects residents from tsunamis.
- The two-layered design includes a self-sufficient maritime city on top and a sea-cooled data center below for city management, healthcare, and drug discovery.
- Dogen City will accommodate 10,000 residents and up to 40,000 visitors.
- It will have food production facilities, schools, hospitals, sports areas, offices, and parks.
- New farming technology will enable residents to produce 7,000 tons of food annually using seawater.
- Advanced healthcare assessments and medical care will be available.
- A dedicated space tourism launch and landing zone is included.
- Completion is planned for 2030, but location and cost are undisclosed.
- South Korea's Busan has also planned a sustainable floating metropolis, potentially housing 100,000 people.
- The Netherlands has a thriving Schoonship neighborhood with 46 homes, 100 residents, since 2021, serving as a model for self-sufficient, eco-friendly floating cities.
Cancer Vaccines
- Scientists are developing personalized cancer vaccines to fight each person's unique cancer.
- Dr. Catherine Wu and her team at the Dana-Farber Cancer Institute are pioneering this research.
- This is based on using the body's immune system, inspired by how bone marrow transplants help leukemia patients.
- The initial study involved six melanoma patients.
- Personalized vaccines containing each patient's unique cancer proteins were created.
- Through a seven-shot course in 2015, four showed no recurrence by 2017.
- The two with more advanced cancer saw tumor disappearance after four more doses.
- All six patients were declared cancer-free by 2021.
- Though the sample size was small, the research shows personalized vaccines' effectiveness.
- This research earned Dr. Wu the Sjöberg Prize in February 2024 ($1 million).
