The early development of radar was driven primarily by military imperatives, and the targets that were to be detected were mainly aircraft and ships. It was no surprise that echoes were also received from terrain and from rainstorms, but the discovery, during World War II, that birds were often detectable was less expected. As the technology developed, and specially after transmission at the shorter ‘microwave’ wavelengths became commonplace, echoes from insects were also identified. In the late 1940’s and the 1950’s, radar technology was adapted rapidly to the needs of meteorologists, while ornithologists pioneered the use of defence and air-traffic control radars to study bird migration.
Radar observations of insects, however, were relatively sparse until the early 1960’s, when radar meteorologists became rather intensely interested in a type of warm-weather echo that appeared, puzzlingly from their perspective, when there was not a cloud in sight. Perhaps spurred by the meteorologists’ observations, entomologists began their own exploitation of the technology in 1968, when a rather modest radar, built by G.W. Schaefer specifically for insect observation and operated in West Africa just south of the Sahara, proved to be very effective.

“In recent years, no more than a week goes by without news of a cosmic discovery worthy of banner headlines. While media gatekeepers may have developed an interest in the universe, this rise in coverage likely comes from a genuine increase in the public’s appetite for science. Evidence for this abounds, from hit television shows inspired or informed by science, to the success of science fiction films starring marquee actors, and brought to the screens by celebrated producers and directors. And lately, theatrical release biopics featuring important scientists have become a genre unto itself. There´s also widespread interest around the world in science festivals, science fiction conventions, and documentaries for television.

The Chamber of Commerce Brazil-Canada (CCBC) hosted Canada Day 2024, aimed at providing opportunities for young Brazilians who wish to do an exchange program, study, and explore the Canadian job market. The event featured representatives from the Consulate General of Canada in Brazil, who highlighted the efficiency of visa processing, allowing students to begin their studies in the country.
During the event, experts from various universities and educational institutions in Canada shared information and provided clarifications for students, offering a comprehensive view of the available opportunities.
Canada leads the list of the most sought-after destinations by Brazilians for studying abroad. According to the 2023 Belta Survey released by the Brazilian Association of Exchange Agencies, the number of Brazilian students seeking to study abroad grew by 18% in 2022 compared to the pre-pandemic period. This is because the region offers excellent quality of life, safety, and academic options, as well as work opportunities during and after studies, and the possibility of obtaining permanent residency in Canada.
For those who are thinking about studying in Canada, it is essential to pay attention to the registration deadlines offered by the institutions and to prepare the documentation, such as sending transcripts, English test results and necessary proof of income. The institutions present at the event highlighted the importance of starting the application process in advance, as soon as each university opens its applications.
Furthermore, to obtain a student visa for Canada it is necessary to follow a series of steps after receiving the acceptance letter from the educational institution and the scholarship. There are different types of visa, each suited to specific situations: the SX-1, for shortterm courses (up to 24 weeks), which requires an acceptance letter; the V-1, a tourist visa that can also be used for courses of up to 24 weeks; and the S-1 Study Permit, required for courses longer than 24 weeks.
To speed up the process, it is recommended to seek help from an exchange agency that offers guidance and support during all stages. In addition to the acceptance letter, you must have a passport valid for at least six months, demonstrate family ties in your country of origin, prove your financial capacity to support yourself in Canada during the study period and send all the necessary documentation, detailing your plans. For courses lasting more than six months, a medical examination is also required.

White Blood
Doctors in Germany faced something they had never seen before. A 39-year-old patient’s blood was so pale and thick that it looked like milk. The medical condition was not a mystery. The (1) nearly comatose patient suffered from extreme hypertriglyceridemia. It is caused by too much fat in the blood.
Siphoning off the offending triglyceride molecules and returning the cleaned plasma to the body usually solves the problem. However, when staff tried the normal route, his viscous blood clogged the hospital’s filtering equipment. Not once, but twice. The problem was a record amount of triglycerides. Around 500 mg/dL is considered “high.” The man’s count read (2) an astonishing 18,000 mg/dL.
Desperate to save his life, doctors (3) resorted to an ancient remedy abandoned by modern medicinebloodletting. A good amount of the white gunk was drained and replaced with red blood cell concentrates and saline solution. It worked. (4) Although the cause of the severity is unknown, the patient’s genes, obesity, and irregular consumption of his diabetes medication might have combined to cause the mother of all hypertriglyceridemia cases.

Bringing Physics Into The Doctor’s Office?
Particle physics is a scientific discipline that tries to understand the tiniest building blocks of the universe. These particles are so small that we cannot see them with our eyes or even with advanced microscopes. To study them, particle physicists use huge, powerful machines called particle accelerators, which get particles moving at very high speeds and then smash them into each other. Examining what comes out of these collisions, using giant detectors, can teach scientists a lot about the tiny particles that make up atoms, like electrons and quarks, and even the famous Higgs boson. Nuclear physicists can also use and study radioactive isotopes – atoms that give off a kind of energy called radiation – in their experiments.
On the surface, particle physics and medicine might seem as different as plumbing and carpentry. But some particle physicists have the same goal as doctors – they would ultimately like to see their research improve human lives. Working together, doctors and particle physicists can combine tools and ideas from these two separate disciplines to improve the way diseases, like cancer for instance, are diagnosed and treated. When particle physicists collaborate with doctors, the sky(scraper) is the limit!

What does ‘brain dead’ really mean? The battle over how science defines the end of life
Ideological differences threaten to muddy the definition of death in the United States – with potentially negative consequences for clinicians and people awaiting organ transplants. • Max Kozlov • Published on 11 July 2023
Dead in California but alive in New Jersey: that was the status of 13-year-old Jahi McMath after physicians in Oakland, California, declared her brain dead in 2013, after complications from a tonsillectomy. Unhappy with the care that their daughter received and unwilling to remove life support, McMath’s family moved with her to New Jersey, where the law allowed them to lodge a religious objection to the declaration of brain death and keep McMath connected to life-support systems for another four and a half years. Prompted by such legal discrepancies and a growing number of lawsuits around the United States, a group of neurologists, physicians, lawyers and bioethicists is attempting to harmonize state laws surrounding the determination of death. They say that imprecise language in existing laws – as well as research done since the laws were passed – threatens to undermine public confidence in how death is defined worldwide. “It doesn’t really make a lot of sense,” says Ariane Lewis, a neurocritical care clinician at NYU Langone Health in New York City. “Death is something that should be a set, finite thing. It shouldn’t be something that’s left up to interpretation.” Since 2021, a committee in the Uniform Law Commission (ULC), a non-profit organization in Chicago, Illinois, that drafts model legislation for states to adopt, has been revising its recommendation for the legal determination of death. The drafting committee hopes to clarify the definition of brain death, determine whether consent is required to test for it, specify how to handle family objections and provide guidance on how to incorporate future changes to medical standards. The broader membership of the ULC will offer feedback on the first draft of the revised law at a meeting on 26 July. After members vote on it, the text could be ready for state legislatures to consider by the middle of next year.

In the UK, the best (1)________of how this might work is the tax on the soft drinks industry. It mainly (2)________manufacturers reformulating products, and didn’t put the burden on the consumer. A meat tax would mainly incentivise manufacturers to put (3)________ meat in products (eg, a sausage might have 60% meat instead of 70%) but there is no government appetite for it.
There are many reasons for this, including lobbying from interest groups saying it would (4)________the domestic farming sector. Neoliberal governments also have a tendency to believe the market will internalise health and environmental costs if better information is provided, and the government does not want to appear to be a “nanny state”, says Dominic Moran, professor of agricultural and resource economics from the University of Edinburgh. There is also concern the burden of taxes falls disproportionately on lower income groups. “But this isn’t (5) ________,” says Moran.

Ultra-processed products now make up 60% of our diet – and they’re killing us
Strange as it may seem, food has replaced tobacco as the leading cause of early death globally. Each year,more people die in America from illnesses caused by poor diet than were killed fighting in every war in US history combined. In the UK the situation is equally 1. dire. Officially, the health effects of food are entirely due to its nutritional content – the amount of fat, salt, sugar and fibre it contains. The current system leaves it up to you to read the detailed information on the pack and decide how much to eat based on recommended values, and if you have children, you’ll need to know the values for them too. This is nigh-on impossible for most people – but even if you were able to calculate exactly how much fat, salt and sugar you were consuming in each 2. mouthful, you would still be neglecting one vital determinant of health – how the food was processed. You might feel like you’ve heard all this before. People have expressed concern about “processed food” for a long time, but it’s not always been an easy concept to 3. pin down. After all, we have been processing food for hundreds of thousands of years. The human diet was invented by primarily female domestic scientists who modified plants and animals by milling, shaking, pounding and grinding them, or altering them via fermentation and heat, before salting, smoking and drying them for preservation. Food processing has shaped almost every aspect of our bodies: we have the shortest guts of any animal our size because part of their job is outsourced to our kitchens. We are the only animal that must process its food to survive. Processing is fine.
But just over a decade ago a team of scientists in Brazil noticed a 4. paradox in the data from their national nutrition surveys. Obesity had gone from being rare, to being the country’s dominant public health problem – even though people were buying less oil and sugar. What theywere eating more of was industrially processed food: biscuits, emulsified breads, confectionary and so on. The team developed a definition that distinguished between traditional food, whole or processed, and these items, which they termed ultra processed foods, or UPFs for short.
