The Davidson Institute at the Weizmann Institute is playing a huge role in advancing an appreciation for the study of science
By BERNIE BELLAN Dr. Liat Ben-David is a scientist who has devoted a good part of her life to educating people about science.
Having graduated with a degree in Molecular Biology from the Weizmann Institute of Science in Rehovot, Israel, in 1991, for the past seven years Dr. Ben-David has been CEO of the Davidson Institute, which is the educational arm of the Weizmann Institute.
A fourth-generation sabra, Dr. Ben-David speaks flawless English without a trace of a Hebrew accent, although I made the mistake of asking her whether she was originally from the US since, if she hadn’t corrected me, I would have sworn she was either American or Canadian-born.
Dr. Ben-David was in Canada recently to speak at an event in Toronto sponsored by the Weizmann Institute focusing on the power of science education to help foster resiliency in children and youth. She took time out from her busy schedule to participate in a Zoom call during which she explained what the Davidson Institute is all about – and how science education has come to play an even more important role in the lives of many Israelis over the past 11 months than it had previously.
To begin with, here is some information about the Davidson Institute taken from the Weizmann Institute website: “The Davidson Institute of Science Education is a non-profit organization that serves as the educational arm of the Weizmann Institute of Science. We believe in connecting people to science, and therefore we initiate, organize and operate a wide range of educational programs. We strive to be a professional epicenter for students, parents and the general public, as well as for teachers and academics, in both government and education.”
“We create activities for all sectors of Israeli society,” Dr. Ben-David explained. Not only is “science education part of our mission,” she continued, “we believe it is part of our responsibility to create a more logical society for everyone.”
There are “three components of scientific literacy” that the Davidson Institute promotes, Dr. Ben-David said: “knowledge, skills, and values.”
“You have to know which values you want to strengthen,” she noted, “so we can help make better lives.”
To that end, the Davidson Institute has made inroads into all facets of Israeli society. “We try to engage everyone in Israel,” Dr. Ben-David says. “We work in both Hebrew and Arabic.”
The Weizmann Institute -and through its education arm, the Davidson Institute, is involved in practically all areas of scientific endeavour. If you look at the Davidson Institute website (https://davidson.weizmann.ac.il/en) you will find articles on a dizzying range of subjects – from spacewalks to head surgeries in Ancient Egypt, to childhood mental disorders and so on, all written in an easy-to-understand English. You won’t be intimidated into thinking this is way too academic to understand.
The goal of the Davidson Institute is to inspire people to view science as a relevant part of their lives, Dr. Ben-David said. Educators from the institute go out to even the most remote communities in Israel, as well as make deliberate efforts to target “at-risk youths.”
Our goal is to “build esteem and self-confidence” within those young people, she explained, many of whom have dropped out of school.
While not all of them will succeed, the Davidson Institute has had a “40% success rate” in getting those drop-outs to return to school, Dr. Ben-David added.
“Science is a healing tool,” she observed.
Now, more than ever, since life in Israel has been so disrupted as a result of everything that has happened since October 7, educators from the Davidson Institute have been dealing with new challenges.
“During the past year, unfortunately, we have found ourselves working with displaced families” who have had to leave their homes” as a result of the Hamas attacks of Oct. 7th on the south as well as the attacks posed by Hezbollah in the north, Dr. Ben-David observed. “We are giving them some sense of normality and stability.”
For instance, she noted that “we’ve created seminars at Davidson” where students who have been displaced from their home schools “are given a week where we give them a full blast of science.”
“They work on science projects that are included in matriculation,” Dr. Ben-David explained.
And, educators going out from Davidson aren’t only working with high school students. “We work with kids in elementary schools age 10 and up,” she said, “also with their teachers.”
Those teachers may not have a particular background in science, Dr. Ben-David explained.
Davidson educators also don’t restrict their attention to trained teachers.
“We work with instructors who are not professional teachers on giving them instruction in science,” she noted.
I asked Dr. Ben-David to give me an example in which someone from Davidson has reached out to a child who has been traumatized by what has been happening in Israel since October 7.
She told me of one particular young girl who had been so afraid that she was going to be killed by a missile that she spent the better part of her day hiding under her bed.
Educators from Davidson came to visit the child and found out that she loved Harry Potter books. They “discussed with her the science of Harry Potter magic,” and whether there was something that might actually be plausible about some of the magic.
“At first she just peeked out at us,” Dr. Ben-David continued, “then she started asking questions” – and soon she was fully engaged in talking with the instructors.
The Davidson Institute runs several programs that aim to attract students, both from within Israel and beyond.
For instance, Dr. Ben-David pointed to a “gap year program,” now in its sixth year of existence – for high school graduates where Davidson sends them to remote communities as “science ambassadors.”
And, including during this past year, Davidson also has “several international programs” for students “from all over the world,” she explained. Not only do those students get to do science, “they get to know Israel and each other,” Dr. Ben-David said.
There are still many online programs for students, she noted, including one called “Windows to the Future,” in which “once a month students from all over the world meet a Davidson scientist” online.
“Some countries have approached us to develop different pedagogies,” Dr. Ben-David said. “Covid didn’t stop us; neither did the war.”
I wondered though, whether the trend toward academic boycotts of Israeli institutions of higher learning and, concomitantly, Israeli academics, has had a very adverse effect on Davidson Institute programs that reach out beyond Israel.
“We don’t ignore the elephant in the room,” Dr. Ben-David admitted but, in addition to the “100,000 participants” Davidson Institute programs have in Israel itself – in partnership with most municipalities, we reach another “3 million” from Israel and outside digitally, she said.
While Israel’s image in much of the world has suffered greatly as a result of its war in Gaza, Israel’s reputation as a scientific powerhouse has not diminished – and institutions like the Davidson Institute are serving to maintain that image throughout the world.

Skipping breakfast: Does it help you lose weight or is it bad for your health?
Breakfast is known to be an important meal – and yet many people leave the house without it. But what are the consequences for your health if you skip breakfast?
Whether it’s because of time pressure, to lose weight or because you’re not hungry yet – many people skip breakfast in the morning. There are different opinions. But to really have full energy for your next round at Betamo casino Canada you better not skip this very important meal.
Skipping breakfast: A good idea to lose weight?
Skipping breakfast is a common weight loss tip. Provided that you save the calories for breakfast and don’t eat them with another meal. This assessment is supported by studies:
A meta-analysis from 2023 found a significant correlation between skipping breakfast and a reduction in body weight.
A study from 2020 shows similar results: Skipping breakfast had a slightly positive effect on weight loss.
Another analysis from 2019 also shows that the study participants who skipped breakfast had a small – but significant – weight reduction of just under half a kilo.
However, these studies only show slight effects on weight and appetite. What’s more, some of the scientists also point to negative effects.
Skipping breakfast: What speaks against it
There are many voices that clearly speak out against skipping breakfast. For example, Anja Bosy-Westphal, President of the German Society for Nutritional Medicine, told Zeit magazine that skipping breakfast does not help to maintain lost weight in the long term. “People who skip breakfast for a long time are more likely to be overweight,” explains the expert. The effect persists even if other unhealthy habits are ruled out as the cause.
Skipping breakfast increases the risk of diabetes and obesity
In order to maintain your weight and eat healthily, you should therefore eat breakfast. Bosy-Westphal goes on to explain that glucose and energy metabolism work less efficiently in the morning. “If I eat the same meal once for breakfast and once for dinner, the blood sugar level rises less in the morning.” On the other hand, more calories are burned immediately after eating.
In the evening, the effect is reversed and we store more energy. The expert is generally in favor of never skipping a main meal. However, if someone “absolutely” wants to do this, for example because they are intermittent fasting, she says it should ideally be the evening meal.
Eating breakfast regularly has a positive effect on blood sugar levels and prevents diabetes. Conversely, according to Bosy-Westphal: “The more often you skip breakfast, the higher the risk of developing diabetes”. This is because eating early in the day helps the body to adjust the metabolism correctly and reduces the risk of obesity and metabolic diseases.
Increased risk of cardiovascular disease
Another negative effect associated with skipping breakfast is an increased risk of cardiovascular disease. A study from 2023 shows: A late first meal of the day (for example, by skipping breakfast) is associated with an increased risk of cardiovascular disease. Every hour later (9 a.m. instead of 8 a.m.) increased the risk by 6 percent.
Skipping breakfast to lose weight: A good idea?
Whether skipping breakfast really helps you lose weight is controversial – some experts even suspect the opposite. At the same time, the scientists point out that breakfast is not the only thing that matters. This is because the participants who ate late drank more alcohol, went to bed later and ate more irregularly compared to those who ate early.
Skip breakfast: This is the recommendation of the DGE
The overall study situation is not clear. The results are partly limited by methodological weaknesses such as small study sizes and the fact that physical activity was not recorded. The German Nutrition Society (DGE) therefore does not currently give a clear recommendation as to whether skipping breakfast helps with weight loss or not:
At present, no scientifically validated statement can be made regarding the relationship between meal frequency and body weight regulation in healthy adults, so the German Nutrition Society (DGE) makes no recommendation in this regard. The energy balance is decisive for the development of body weight.

How often you should cycle per week to get fit
Cycling is an excellent way to get or stay fit. But how often, how long and how intensively should you cycle to achieve this?
What does it actually mean to be fit? The word “fit” means nothing more than “suitable”. However, we generally understand “fit” as a certain level of training that is not only healthy, but also makes many everyday things easier for us – for example, just catching a streetcar or playing tag with the children. Last but not least, basic fitness can be a basis for more ambitious training or sporting goals (a long bike ride, a 10-kilometer run or similar).
Cycling is basically a very good way to get or stay fit, as it trains our endurance and most major muscle groups, is easy on the joints and, in terms of intensity, is easy to control. Numerous studies also show that cycling is healthy and a good option for building up fitness. But who should cycle how often and for how long is very individual and depends above all on the current state of training and health. So you will be calm after and can focus completely on National Casino.
This is how often and how fast beginners should (be able to) cycle
Let’s assume that you want to do something for your fitness again after a long break from sport. The best way to start is to take stock: grab your bike and go for a ride to see how long you can keep going and at what pace. If you haven’t exercised for a very long time or have never done so regularly and/or suffer from pre-existing conditions, you should check with your doctor beforehand whether and how much strain you can put on your cardiovascular system.
After taking stock, you should start training slowly. In the beginning, it is enough for beginners to cycle on flat terrain for 20 to 30 minutes about three times a week.
Now for the right intensity and the right pace: For (re)beginners, the following applies: If you still have just enough air to keep yourself entertained while riding, then you’re on the right track. If you want, you can of course also train with a heart rate monitor, where the target heart rate for most people is around 120 to 130 beats per minute. However, as the exercise heart rate is very individual and depends on many factors such as age, training condition, etc., intensity control via the “conversation test” works at least as well.
If you are riding on flat terrain, you will probably reach a speed of around 18 to 20 kilometers per hour in calm conditions.
Building fitness means building new habits
This training area is called the foundation area, by the way, and this is precisely your most important goal: laying a solid foundation for your fitness. Continuity is crucial, especially at the beginning – so really try to cycle three times a week – even if it’s only 15 minutes, that’s still better than not cycling at all. This will help you get into a steady rhythm and each time you cycle it will be easier for you to get going.
According to studies, it can take up to three months for new habits to become so integrated into your life that you find them as easy as brushing your teeth – so keep at it!
If you then have no problem sticking to the basics for around 30 to 40 minutes three to four times a week, you will have built up a solid base level of fitness. This will also help you achieve the WHO’s recommended exercise target of at least 150 minutes of exercise per week. Once you have reached this basic level of fitness, you can of course always increase your training, depending on your goals.
Combining cycling with strength training
Cycling is very good endurance training. However, it is also important for our health and fitness to train our strength. Otherwise, as we get older, we lose muscle mass, which can lead to back pain and the like, but also promotes weight gain – because muscles use energy and therefore calories even at rest. Strength training also improves your performance on the bike.
All it takes is 10 to 15 minutes two to three times a week. And you don’t have to go to the gym or buy any equipment. Classic exercises such as push-ups or squats are very effective and anyone can easily do them at home.
Tip: There are many practical apps with short workouts that strengthen the entire body, for example the free app Seven – 7 Minute Workout (for Apple or Android devices). It gives you suggestions for exercises and – especially important for beginners – shows you the correct exercises to do.

Sleepmaxxing: Sleep better with these tips
Sleepmaxxing is trending on social media: targeted tricks and habits are designed to make your sleep as restful as possible. We explain what the hype is really about.
If you’re active on social media, you’ve probably heard the term “sleepmaxxing”. At the end of 2024, this tag already had 98.6 million posts on TikTok. This term, which literally means “maximizing sleep”, i.e. “getting the most out of your sleep”, is all about getting the perfect night’s sleep. From an optimized sleeping environment to the ideal evening routine, nothing is left to chance with Sleepmaxxing – all for the purpose of perfect nightly rest for your next round of TonyBet Canada.
Sleepmaxxing – what really works?
As is so often the case with health tips on social media, the Sleepmaxxing methods should also be taken with a grain of salt. Most of the popular tips for better sleep are not scientifically proven and will definitely not be the panacea they are promoted as on TikTok and the like.
However, some behaviors can actually help you improve your sleep quality or fall asleep faster. Here are some tips that can help you sleep better.
1. evening routine for better sleep
Fixed bedtimes and other rituals can benefit the quality of your sleep. Regular rituals help your body to adjust better to sleep. You can try out these methods, for example:
- Fixed bedtimes: If possible, go to bed at the same time every day and get up at the same time – even at the weekend. This stabilizes your sleep rhythm and the hormone balance that controls your tiredness.
- Avoid screens in the evening: The blue light from cell phones, laptops and televisions inhibits the production of the sleep hormone melatonin. Put your cell phone away at least an hour before going to bed and try using blue light filters if you like.
- Relaxation rituals: Reading, meditation or a warm shower can help you to calm down more quickly.
- Sleeping tea instead of caffeine: Avoid coffee or energy drinks in the evening. Instead, opt for herbal teas with valerian or lavender.
2. create the ideal sleeping environment
Your sleeping environment can have a major impact on the quality of your sleep. Your environment has a big impact on the quality of your sleep. With a few adjustments, you can significantly improve the conditions for restful sleep:
- Darkness: Sources of light at night disturb your internal clock. Darken your bedroom as much as possible or use a sleep mask.
- Quiet: Noise can interrupt your sleep. Earplugs or a white noise app can help combat noise.
- Cool temperature: The optimum sleeping temperature is between 16 and 19 degrees Celsius. You should briefly air your bedroom twice before going to bed.
- Comfortable mattress and pillow: A sagging mattress or the wrong pillow can massively affect your quality of sleep. Make sure your back and neck are well supported and find the right type of mattress for you.
3. diet and exercise for better sleep
Those who live healthily also sleep better: diet and exercise can influence your sleep. Diet and exercise also have a major influence on your sleep. The following tips can contribute to a healthier sleep:
- No heavy food before sleep: fatty or highly seasoned foods can put a strain on your digestion and disrupt your sleep.
- No alcohol to help you sleep: Although alcohol makes you tired, it worsens the quality of your sleep and makes for restless nights.
- Regular exercise: Exercising helps you to sleep better – but intensive training directly before bedtime can keep you awake. It’s therefore better to schedule your workout for the morning or afternoon.
