Bees with a taste for rotting flesh evolved to have guts like vultures, researchers find – USA TODAY

Murder hornet nest found in Washington state

Officials in Washington state said Thursday they had destroyed the first Asian giant hornet nest of the season, which was located near the town of Blaine along the Canadian border. The Asian giant hornets are sometimes called murder hornets because they prey on other bees. (Aug. 26)

While most bees feed on pollen and nectar, scientists say some bees havedeveloped a taste for rotting flesh.

Researchers have learned that a stingless, tropical bee has evolved to have an extra tooth for biting and a gut that more closely resembles those of vultures in order to munch on meat, according to a studypublished last week in the American Society of Microbiologists journal mBio.

The reason? Likely due to intense competition for nectar, study co-author Laura Figueroa told USA TODAY.

"When asked where to find bees, people often picture fields of wildflowers.While true for almost all species, there is a group of specialized bees, also known as the vulture bees, that instead can be found slicing chunks of meat from carcasses in tropical rainforests," the authors wrote in the study titled, "Why Did the Bee Eat the Chicken?"

Only three bee specieshave evolved to exclusively eatmeat, though other speciesthat forage for pollen and nectar may also consume animal carcasses when they are available, according to the study.

To study these species, researchers visited Costa Rica, where they hung raw chicken from branches to attract vulture bees.

They dodged bullet ants and problem solved when the chicken was stolen by other animals, said Figueroa, a postdoctoral research fellow at Cornell University. Researchers fromColumbia Universityand the University of California, Riverside also participated.

While stingless bees usually collect pollen in small baskets on their hind legs, the researchers saw vulture bees use the baskets to carry their meat, according to the study.

"They had little chicken baskets,"said Quinn McFrederick, a UC Riverside entomologist, in a statement to UC Riverside.

Researchers also noticed the bees preferred fresh meatthat was just starting to decompose and would avoid fully rotted meat.

Upon further study, they found the vulture bee gut microbiome is full of acid-loving bacteriasimilar to those found in vultures and hyenas, Figueroasaid. One of the bacteria types, calledLactobacillus, is also found in a lot of fermented foods like sourdough, while another bacteria found in vulture bee guts,Carnobacterium,is associated with flesh digestion.

Figueroasaid the bacteria helps protect the bees from pathogens found in rotting meat.

"For us, we can tell if we open our fridge and something has gone bad. And if you were to eat it, it's going to make you sick," she said. "So animals that are scavengers have evolved this microbiome and this physiology to deal with that bacteria and still be able to take advantage of that food source."

Figueroa said vulture bees still produce sweet, edible honey, though she has never tasted it herself.

But many carnivorousbees are not quite as sweet. Though they can't sting, some species can bite and a few "produce blister-causing secretions in their jaws, causing the skin to erupt in painful sores," entomologistDoug Yanega, one of the study authors, told UC Riverside.

Still,Figueroa sees the insects asbeautiful. When she was first introduced to the bees in 2015, she quickly "fell in love with them" and sought to do more research on the species, which was lacking studies.

"They're not scary even though they may sound a little bit scary," she said.

She said she hopes the study will encourageenvironmental conservation of the areas where the bees liveand that it"gets people excited about the diversity of animals in the world."

The research team plans to continue studying vulture bee microbiomes in hopes of documenting more of the bacteria, fungi and viruses in their bodies.

"There's still so much to learn about these bees," Figueroa said. "There's a lot of questions still to be answered."

Warmer winter can cause problems for rice farmers with red rice, weedy rice – talkbusiness.net

Capt. John Thurbers ship was badly damaged from a violent storm. It limped into the harbor in Charleston, South Carolina sometime in 1685. While the ship underwent repairs, Thurber met Dr. Henry Woodward and the two became friends.

As a token of gratitude, the captain gave the doctor a bag full of rice seeds he had acquired from Madagascar, just off the coast of southern Africa. It was the first time rice would be grown in the Western Hemisphere.

The Carolinas had a couple of advantages when it came to growing rice. Those colonies had fertile soil, plentiful water and African slaves that were experienced in growing rice on farms in their native continent.

Along with the rice also came another plant called red rice, a weed that often grows in rice paddies. Red rice in the field was a problem for rice growers, but at least it was easy to spot. But years of out-crossing with cultivated rice varieties has resulted in weedy rice, which appears in a spectrum of hues, some of which can blend in nicely with the crop.

But that camouflage is deceiving, and the result can be loss of both yield and rice quality, said Nilda Burgos, professor of weed physiology and molecular biology for the Arkansas Agricultural Experiment Station, the research arm of the University of Arkansas System Division of Agriculture.

The issue is that red rice is the same genus and species as cultivated rice, Burgos said. That leads to gene flow, when cultivated rice cross-pollinates with the weeds that survive from one year to the next. A problem may not manifest after a single rice season, but after repeated years of fraternization between weedy and domestic rice, the weeds present problems.

Burgos said she didnt expect to find a big problem with red rice at first because rice is self-pollinating. That slows the rate of cross-pollination, especially since the reproductive window of individual varieties is relatively narrow.

But we found that things begin to happen after multiple seasons, especially in fields where hybrids have been growing for many years, Burgos said.

Rice grains that fall out and are left in the field will grow up volunteers in following years. Outcrossing with weedy rice results in numerous offspring that manifest many hues of off-color rice, and varying maturity dates. This leads to a wider window for cross-pollination, which leads to more varieties of weedy rice.

The volunteers are bridges for outcrossing with weedy rice, Burgos said.

Because weedy rice often matures later than conventional varieties, its development is often stunted before grain maturity when cooler weather comes on in the fall. Second or third generations of weedy rice outcrosses only exist when it stays warm, Burgos said.

That makes weedy rice a bigger problem in countries with tropical climates, Burgos said. But its also a problem as warm weather stretches longer into fall in the U.S.

When it comes to global warming, weeds are going to love it, Burgos said. Outcrossing and herbicide resistance will become worse.

The rise of weedy rice is not anyones fault, she said. Its a combination of factors, including plants, weather, climate, economics, available agricultural technology, available knowledge and farming practices.

Hybrids have passed along herbicide resistance to weedy rice, Burgos said.

Hybrid rice is more compatible with red rice and the outcrossing rate is higher, Burgos said. The outcrossing rate in hybrids is double that of conventional rice varieties.

Thats still low, because of rice being self-pollinating, Burgos said. But it means that it takes fewer seasonal cycles before problems begin to mount up.

Besides causing headaches for weed control, the varying hues of weedy rice mar the consistent white color desired at the rice mills, Burgos said. That causes devaluation of the crop, and a discounted price paid to the farmers.

Being the same species as cultivated rice means that weedy rice is also competing with the crop for resources throughout the growing season, robbing the crop of nutrients and water, Burgos said.

The variability in maturity date also means the weedy rice may be overly mature or under-mature at harvest. Grains from overly mature weedy rice shatter in the field, leaving seed that will grow up as weeds in the following season, or during milling, damaging a crops milling yield.

Under-mature weedy rice at harvest means moisture content will be too high, complicating rice drying.

Plant height of weedy rice is consistent in the first generation, Burgos said. But it begins to vary in succeeding generations.

With all this going on, Burgos said, weedy rice wreaks havoc in the rice field. Burgos quantified yield loss for varying varieties and growing conditions. The weeds also result in lower rice quality and, in worst cases, can severely damage the whole crop.

Avoiding damage from weedy rice begins with zero tolerance weed management, Burgos said. Dont leave anything in your field. And dont forget the edges of the fields.

Many growers clean up their fields thoroughly, but neglect the edges and ditches, Burgos said. The following year, weedy rice sprouts up at the peripheries of rice fields and spreads in from the edges.

Rice is a top agricultural commodity in the Natural State.

Arkansas rice exports accounted for $722 million of the states total of $3.1 billion in agricultural exports. Despite the states position as the top rice producing and exporting state, farmers in 2021 dropped the number of rice acres in Arkansas. Decade high prices for corn and soybeans prompted the shift. Arkansas rice growers planted about 18% fewer acres this year, falling from about 1.46 million acres in 2020 to about 1.24 million acres. Nationally, rice acreage fell by about 10%, from 3 million acres planted in 2020 to about 2.7 million acres in 2021. This includes long, short and medium grain rice.

Rotating hybrid rice with conventional varieties can also slow gene flow and inhibit development of herbicide resistant weeds, Burgos said. Rotating rice with other crops, like soybeans, and the different weed control strategies used with those plants can help keep rice fields clean. She also advises rotating weed control strategies.

Make sure, whatever you use, you leave no weedy rice in the field. Farmers are seeing more resistant weedy rice, Burgos said. Any field that has had Clearfield in it for many years will be more likely to see it.

What the First Two Laws of Thermodynamics Are and Why They Matter – Interesting Engineering

Thermodynamics is the branch of physics that studies the relationship between heat and other forms of energy. It's especially focused on energy transfer and conversion and has a lot to contribute to the fields of chemical and mechanical engineering, physical chemistry, and biochemistry.

The term thermodynamics was likely first coined by mathematical physicist William Thompson, also known as Lord Kelvin, in his paper On the Dynamical Theory of Heat (1854).

Modern thermodynamics is based on four laws:

In this article, well be focusing on the first and second laws of thermodynamics.

The first law of thermodynamics is also known as the law of conservation of energy. Given that the energy cant be created or destroyed, the total energy of an isolated system will always be constant because, and can only be converted into another form of energy or transferred somewhere else in the system.

The formula of the first law of thermodynamics is U = Q W, where U is the change in internal energy U of the system, Q is the net heat transferred into the system (the sum of all the heat transfers of the system), and W is the net work done by the system (the sum of all work performed on or by the system).

The second law introduces the concept of entropy in thermodynamics. Entropy is a physical property that measures the amount of thermal energy in a system that is unavailable for doing useful work. The energy that cant do work turns into heat, and the heat increases the molecular disorder of the system. Entropy can also be thought of as a measurement of that disorder.

The second law of thermodynamics states that entropy is always increasing. This is because, in any isolated system, there is always a certain amount of energy that is not available to do work. Consequently, heat will always be produced and this naturally increases the disorder (or entropy) of the system.

The increasing entropy (S) equates to the heat transfer (Q) divided by the temperature (T). This is why the second law of thermodynamics can be expressed with the formula S =Q / T.

As stated above, the first law of thermodynamics closely relates to the law of conservation of energy, which was first expressed by Julius Robert Mayer in 1842.Mayer realized that a chemical reaction produces heat and work and that work can then produce a definite amount of heat. Although this is essentially a statement of the conservation of energy, Mayer was not part of the scientific establishment, and his work was ignored for some years.

Instead, German physicist Rudolf Clausius, Irish mathematician William Thomson (Lord Kelvin), and Scottish mechanical engineer William Rankine would have a greater role in developing the science of thermodynamics and adapting the conservation of energy to thermodynamic processes, starting in around 1850.

The second law of thermodynamics has its origin in the work of French mechanical engineerNicolas Lonard Sadi Carnot, who studied steam engines. He is often considered the father of thermodynamics due to his book Reflections on the Motive Power of Fire (1824),which presented a theoretical discussion of the perfect (but unattainable) heat engine Motive power is what wed call work nowadays, and fire refers to heat.

In this book, Sadi Carnot wrote an early statement of the second law of thermodynamics, which was reformulated by Rudolf Clausius more than forty years later. Other scientists also contributed to defining the law: the aforementioned Lord Kelvin (1851), German mathematician Max Planck (1897), and Greek mathematician Constantin Carathodory (1909).

According to thermal science researcher Jayaraman Srinivasan, the discovery of the first and second laws of thermodynamics was revolutionary in the physics of the 19th Century.

The third law of thermodynamics was developed by German chemist Walther Nernst at the beginning of the 20th century. Nernst demonstrated that the maximum work obtainable from a process could be calculated from the heat evolved at temperatures close to absolute zero. The zeroth law had been studied since the 1870s but was defined as a separate law during the 1900s.

The first and second laws of thermodynamics are independent of each other because the law of entropy is not directly derived or deduced from the law of conservation of energy or vice versa.

But at the same time, the two laws complement each other because, while the first law of thermodynamics includes the transfer or transformation of energy, the second law of thermodynamics talks about the directionality of physical changes how isolated or closed systems move from lower to higher entropy due to the energy that cant be used for work.

In other words, the second law of thermodynamics takes into account the fact that the energy transformation described in the first law of thermodynamics always releases some extra, useless energy that cant be converted into work.

The laws of physics explain how natural phenomena and machines work. These explanations not only satisfy our curiosity but also allow us to predict phenomena. In fact, they are instrumental in allowing us to build functional machinery.

As a branch of physics, thermodynamics is no exception for this. If you know how much energy in a system can be used for work, and how much will turn into heat (and theres always a certain amount of useless energy in a system), you can predict how much heat a given machine will produce under different conditions. Then, you can decide what to do with that heat.

Heat is a form of energy and if you know that energy cant be destroyed but only transformed, you could find a way to turn that thermal energy into mechanical energy which is what, in fact, heat engines do.

Given this basic application of the first and second laws of thermodynamics, you can probably imagine how useful they can be in the engineering field. But they can also have applications in chemistry, cosmology (entropy predicts the eventual heat death of the universe), atmospheric sciences, biology (plants convert radiant energy into chemical energy during photosynthesis), and many other fields. Hence the importance of thermodynamics

To break the first law of thermodynamics, wed have to create a "perpetual motion" machine that worked continuously without the input of any kind of power. That doesnt exist yet. All the machines that we know receive energy from a source (thermal, mechanical, electrical, chemical, etc.) and transform it into another form of energy. For example, steam engines convert thermal energy into mechanical energy.

To break the first law of thermodynamics, life itself would have to be reimagined. Living things also exist in concordance with the law of conservation of energy. Plants use photosynthesis to make food (chemical energy for their use) and animals and humans eat to survive.

Eating is basically extracting energy from food and converting it into chemical energy (stored as glucose) which is what actually gives us energy. We turn that chemical energy into mechanical energy when we move, and into thermal energy when we regulate our bodys temperature, etc.

But things may be a bit different in the quantum world. In 2002, chemical physicists of the Australian National University in Canberra demonstrated that the second law of thermodynamics can be briefly violated at the atomic scale. The scientists put latex beads in water and trapped them with a precise laser beam. Regularly measuring the movement of the beads and the entropy of the system, they observed that the change in entropy was negative over time intervals of a few tenths of a second.

More recently, researchers, including some working on Googles quantum processor Sycamore, created "time crystals", an out of equilibrium phase of matter cycling indefinitely between two energy states without losing any energy to the environment. These nanoparticles never reach thermal equilibrium. They form a quantum system that does not appear to increase its entropy which totally violates the second law of thermodynamics.

This is a real-life demonstration of Maxwell's demon, a thought experiment to break the second law of thermodynamics.

Proposed by Scottish mathematician James Clerk Maxwell in 1867, the experiment consisted of putting a demon in the middle of two chambers of gas. The demon controlled a massless door that allowed the chambers to exchange gas molecules. But given that the demon opened and closed the door so quickly, only fast-moving molecules passed through in one direction, and only slow-moving molecules passed through in the other. This way, one chamber heated up and the other cooled down, diminishing the total entropy of the two gases without involving work.

Although we still dont know exactly how to use time crystals, it is already considered a revolutionary discovery in condensed matter physics. Time crystals could, at the very least, significantly improve quantum computing technology.

But theres also something about the concept of perpetual motion without using any energy that unavoidably leads futuristic minds to imagine perpetual motion quantum devices which wont require any additional input of energy such as an unplugged refrigerator that is still able to cool your food down; or more science-fictiony, a supercomputer sustaining the simulation we could be living in.

Supercomputers joined the fight against antibiotic resistance – EurekAlert

The participating researchers work at the Ruhr-Universitt Bochum (RUB), the University of Duisburg-Essen (UDE) in Germany, the University of Portsmouth, UK, as well as at the University of Queensland in Australia and the Weizmann Institute in Israel.

Development of new antibiotics difficult

Developing a new antibiotic is particularly difficult and very few new classes of antibiotics have been developed since the 1960s. In the current study, the researchers follow another approach. They do not develop a completely new type, but start from an already existing antibiotic, which they then modify. To do this, they used a strategy in which they simulated computationally several aspects of the candidates. Among other things, how soluble the antibiotic is, how effectively it penetrates the bacterial membrane and how efficiently it blocks the pathogens' protein production are important for its effectiveness. "The computational evaluation of whether a chemical compound will be active before it is actually synthesised avoids chemical waste." explains Professor Frank Schulz from RESOLV at RUB.

Head-to-head

The past has shown that often not much time passes before resistance to a new antibiotic emerges. Thus, it is to be expected that the bacteria will develop counterstrategies against the researchers' counterstrategies and become resistant to the new antibiotic variant. "Our hope with this study is to show that the resistance mechanisms of bacteria can be addressed in a systematic way with computational strategies that help to make the development of new antibiotic derivatives faster and more affordable" explains Professor Elsa Sanchez-Garcia, head of the Computational Biochemistry group at the UDE and Principal Investigator of RESOLV. "In this way, science can continuously fight back with the computer-assisted development of new antibiotics."

Promising candidate

The results of the supercomputer calculations were tested experimentally. In the study, the research team not only implemented the computer-based simulation approach, but also presented a new promising drug candidate. The drug candidate, which still must be clinically tested, was shown to be up to 56 times more active for the tested bacterial strains than two known antibiotics that are on the World Health Organisation's list of essential medicines. The new antibiotic variant is not only more effective against the target organisms tested, but also shows activity against the three highest ranked bacteria on the World Health Organization's priority list, for which the existing antibiotics tested are not effective. In addition to this success, a library of compounds with antibacterial activity was created, which allows for faster iteration in the development of further antibiotic variants.

IDF ranks Pakistan third in prevalence of diabetes – The Nation

KARACHI - Professor Dr Shamim Qureshi from Department of Biochemistry, University of Karachi said that the International Diabetes Federation (IDF) has ranked Pakistan as third in the prevalence of diabetes following China and India.

According to the IDF, around 33 million people in the country are living with diabetes. These views were expressed by Professor Dr Shamim, while addressing a seminar entitled Access to Diabetes Care here on Wednesday.

The department of biochemistry in collaboration with the University of Karachi Alumni Association (UKAA) Baltimore, Washington, USA organized a poster competition and seminar in connection with World Diabetes Day.

Overall, more than 537 million people are suffering from diabetes across the globe. During the Covid-19 lockdown, we have seen an increase in the prevalence of type-II diabetes around the world as well as in Pakistan as the pandemic has restricted physical activities and obesity was seen on the raise during the pandemic duration, she informed.

She informed the audience that this is very alarming that the country has been witnessing so many people with diabetes and still not taking it seriously.

Dr Abbasi highlighted the significance of standardization of health care establishments and their services in his talk. He said that the Second National Diabetic survey revealed the prevalence of diabetes is 26.19 percent among people over 20 years of age.

He mentioned that it means that every fourth person is diabetic in the country. He stated that health facilities are insufficient and diabetes supplies are not regular. He emphasized structured training of health care providers to cope with the huge burden of diabetes at one end and ensuring uninterrupted affordable diabetes supply at the other. He reiterated that an all-out approach with the right efforts is required on a priority basis.

Dr Abbasi was of the opinion that policymakers and authorities must give due recognition to the fact that more prevention and good control of diabetes will reduce the workload of other specialtiesoriented facilities like cardiac hospitals, kidney hospitals, and neurological centers.

Consultant Dietitian Mariam Abde Ali gave a good account of the implications of a balanced diet on the health of diabetes patients. She said that a healthy diet ensures good health. The success of dietary management in diabetes care depends upon flexibility, portion control, and consistency.

She shared that better lifestyle choice on an all-time basis leads to desired results of medical nutrition therapy. She advised that body weight has to be controlled and maintained in order to keep the body mass index (BMI) below 25 kg/m2.

On this occasion, Dr Tooba Lateef conducted self-health assessment activity through a mobile app called NutriApp (T gamma developers) among participants. Through which participants curiously knew their ideal body weight, BMI, waist to hip ratio, recommended calories, and fluid intake.

She mentioned that these are the key factors in planning a healthy diet to be fit. Dr Shershah Syed, the renowned gynecologist and surgeon, and Dr Sadaf Ahmed, Chief Executive Officer of Advanced Education Institute and Research Center were the chief guests of the event. Both of them emphasized the importance of education for youth especially females. They stated that education is the key for getting awareness not only for any disease including diabetes but also it helps to handle any problem which youth face in their social life.

The final year of students of the biochemistry department (Morning and Evening Program) actively participated in the poster competition and made colorful posters regarding awareness of diabetes and its complications, the judgment of this competition was done by Dr Hina Mudassir (Chairperson, Department of Biochemistry, Federal Urdu University of Arts, Science and Technology), Dr Musarrat Jahan (Assistant Professor, Human Nutrition and Dietetics, Ziauddin Medical University) and Dr Arisha Salman (Assistant Professor, Department of Biochemistry, Dow International Medical College).

The competition was won by Ayesha Shahbaz and received the first prize of Rs3000/- cash while a special prize of Rs1500/- cash was received by Maryum Laiquat, Rida Qamar, Hafiza Fatima Zehra, Ayesha Mustaqim, and Bakhtawar.

During the event diabetes camp to assess free blood sugar and bone mass density BMD) was also arranged by Dr Essa Diagnostic Laboratory in the department of biochemistry. Other speakers of the seminar were Dr Muhammad Zafar Iqbal Abbasi from Baqai Institute of Diabetology and Endocrinology, Mariam Abdeali, Consultant Dietitian and Dr Tooba Lateef, Assistant Professor, Department of Biochemistry.

Robert Koch Prize in Microbiology and Immunology Goes to Andreas Bumler – UC Davis

Microbiologist Andreas Bumler of the School of Medicine and the College of Biological Sciences has been named a recipient of the 2021 Robert Koch Prize, given by Germanys Robert Koch Foundation for achievement in microbiology and immunology a prize that is considered one of the most prestigious awards in science.

Bumler is a professor and vice chair of research in the Department of Medical Microbiology and Immunology, and also affiliated with four graduate groups: Microbiology; Immunology; Integrative Pathobiology; and Biochemistry, Molecular, Cellular and Developmental Biology.

He shares the prize with Yasmine Belkaid, immunologist and senior investigator at the National Institute of Allergy and Infectious Diseases, and adjunct professor at the University of Pennsylvania.

The Robert Koch Prize is shared this year to recognize groundbreaking research that shows how, on the one hand, our microflora train our immune system, and on the other hand, our intestinal epithelium determines the composition of our microflora, and what role disruptions of this dialogue between microflora and us play in infectious and inflammatory diseases, the foundation said in a news release.

UC Davis Professor Satya Dandekar, chair of the Department of Medical Microbiology and Immunology, said: Dr. Bumler has made seminal contributions for advancing our knowledge of the microbial dysbiosis during gut inflammatory infections. He is an exceptional scientist and a great mentor to junior researchers.

The award ceremony is scheduled for Nov. 19 in Berlin. As of today (Nov. 8), the prize of 120,000 euros is the equivalent of $139,075.

Wolfgang Plischke, chair of the Robert Koch Foundation, said: At a time when science and research are constantly at the center of public interest and are often the subject of unfiltered discussion on social networks, it is more important than ever to honor the hard work, unwavering diligence and thirst for knowledge of all the men and women who have dedicated their lives to medicine and biology.

Robert Koch (18431910), after whom the prize is named, founded modern bacteriology. For this he received the Nobel Prize for Medicine and Physiology in 1905. Koch headed the Institute for Infectious Diseases in Berlin from 1891 until his retirement in 1904.

Oncology meets immunology: the cancer-immunity cycle

The genetic and cellular alterations that define cancer provide the immune system with the means to generate T cell responses that recognize and eradicate cancer cells. However, elimination of cancer by T cells is only one step in the Cancer-Immunity Cycle, which manages the delicate balance between the recognition of nonself and the prevention of autoimmunity. Identification of cancer cell T cell inhibitory signals, including PD-L1, has prompted the development of a new class of cancer immunotherapy that specifically hinders immune effector inhibition, reinvigorating and potentially expanding preexisting anticancer immune responses. The presence of suppressive factors in the tumor microenvironment may explain the limited activity observed with previous immune-based therapies and why these therapies may be more effective in combination with agents that target other steps of the cycle. Emerging clinical data suggest that cancer immunotherapy is likely to become a key part of the clinical management of cancer.
